(New books for collections, recommended votes, please, please!) Your attention is the motivation for my writing, thank you! ）

As soon as Geng Jingzhong returned to the palace, he opened the book in the study. In his study, there are all books about ancient science and technology, all kinds of things, but there is not a single book about the books that must be read by readers in this era. After some searching, he really found two books about sugar making. The first book is Song Yingxing's "Heavenly Creations", which he is already familiar with, and the first few times he saw the content was not iron and steelmaking, or about salt making, but he also saw the part about sugar making, but he didn't care about it at that time.

The second book is "Frosting Spectrum" written by a man named Wang Zhuo during the Northern Song Dynasty, which can be called the first sugar-making monograph in Chinese history. This book is complete enough, and it's all about sugar. From the history of the development of sugar production in China, the cultivation method of sugarcane, the equipment for sugar production including pressing and boiling equipment, the technological process, the icing taste, the use and the economic development of the sugar industry, etc. However, the method of squeezing the juice from cow pull reels many times recorded in the book has not changed from now. In "Tiangong Kaiwu", although it is not as refined as "Frosting Spectrum", the content of the summary is more advanced, especially in the clarification of cane juice, the book summarizes a lime clarification process, which is still used in the modern sugar industry.

For a whole day, Geng Jingzhong stayed in the study and did not come out. These theoretical things are very easy to understand, and Geng Jingzhong will soon be able to draw inferences and come up with better ways to improve. If you want sugar to be white, there are two most convenient methods. One of them is the lime clarification process recorded in the "Tiangong Kaiwu". This is very good. According to the principle of reaction. In addition to using lime in addition to carbon dioxide. The combination of the two acts as a fining agent to obtain white granulated sugar. And it seems that this method is relatively easy to do now, so you don't have to worry about being limited by the technology that can't keep up.

In addition, Geng Jingzhong thought that sulfuric acid could also be used to achieve the purpose of clarification, but the specific needs to be verified by table salt. This matter can be left to those Westerners in the real yàn room to do their work, anyway, this is their work all day. Thinking of this, Geng Jingzhong couldn't help but sigh, when will his academy students grow up? For future generations of students. Even if he didn't major in chemistry, he knew that sulfide basically had adsorption ability, bleaching effect on many things, and was very versatile, so Geng Jingzhong quickly remembered it!

For the juice of sugarcane, Geng Jingzhong also has a good method. The source of this inspiration comes from my own personal experiences in my past life. In his previous life, when he was in elementary and middle school, his family processed sweet potato flour and processed sweet potato starch. It is necessary to put the washed sweet potatoes in the machine qì and stir and squeeze the juice, when the sweet potatoes are put into the machine qì. It is also accompanied by the filling of water, and then the mixed juice is precipitated to obtain starch, and according to Geng Jingzhong, the structure of the machine is very simple. If you really want to talk about it, it's similar to the rice hulling device that was just invented. This sweet potato crushing and juicing and sugarcane crushing and juicing are the same, a shaft is placed with several blades, all the sugarcane is crushed, and then entered between the two rollers to press, at the same time, accompanied by water, after the mixed juice comes out, filter out impurities through the filter screen, so that repeated once or twice, not only the efficiency will be greatly increased, and the content of impurities will be greatly reduced.

After writing down the detailed construction by himself, he sorted it out and then ordered someone to send it out. I just have to give orders, and I have the following people to arrange things, and I have already written the content in detail, if I can't do it, it means that the ability of my subordinates is too inferior! As soon as this matter was over, Geng Jingzhong stayed in the palace to accompany his family, and stayed for three days before leaving the palace and going to Mawei. The great development strategy of Mawei Group has been formulated, and the important matters in the near future are also being carried out in an orderly manner, and there are special people in charge. For example, Yao Qisheng and Miao Quanchen are in charge of the affairs of Qingzhang Tianmu and commercial tax plus banks, which is an internal affair. Lee Kwang-di, on the other hand, has been keeping an eye on the affairs of the army and the construction of Luzon, and he has been very busy all day. Geng Jingzhong didn't have much to do with himself, but he felt that it was not a matter to be so idle, so he came out again to inspect everywhere. One to check the progress of all aspects, and the other to dangle in front of his subordinates to increase the sense of saving!

This time Geng Jingzhong came to the Wangzhuang farm not far from Mawei, here he was still six years ago, so that the palace opened up a few farms here to supply the daily consumption of the army, a few years have passed, the supply of meat in the army is very sufficient, it is said that there can be a lot of meat sold to the market, I have not come to inspect it until now, a little irresponsible!

It is said that the people take food as the sky, and the soldiers of the army are even more so, the training of the army is already heavy, and the consumption in ordinary times is much more than that of ordinary people, especially the indispensable is meat, and there is no oil and water for meals, and the soldiers eat it, and they cannot provide enough body to participate in the training, therefore, these farms are very necessary. Geng Jingzhong now arrived at one of the largest farms, halfway between Mawei and Fuzhou but closer to the Mawei military camp. The village is called Longmen Village, and the farm is in the northernmost valley of Longmen Village, where a river leads to the Min River, and there is a small backwater area around several hills, forming a large shoal at the foot of the mountain, with a large number of reeds. The valley at the foot of the mountain is flat and easy to get water, making it a good place to farm a farm.

The farm here, numbered 13, is the thirteenth farm established under the royal government, and is also divided into two areas: livestock and poultry. The thirteenth farm contains 1,500 acres of land per square kilometer, and eleven hills to the north. Eight of the eleven hills are poultry farms, and only three are free-range pigs, cattle and sheep.

At this time, Geng Jingzhong first visited the poultry area, and the first stop was the hatchery. The large incubator was built just three years ago and can hatch 20,000 chicks or other poultry chicks at a time. Artificial eggs have appeared in China for a long time, and they have been very popular since the early Ming Dynasty. It's not a brand new traversal technology. There are many artificial egg incubation methods of the soil method. The most common are the kang incubation method in the north and the vat incubation method in the east China. Geng Jingzhong is not from a breeding background. I haven't given anything good to build yì. But the people below have already recruited masters in this area with high salaries, and the kang incubation method is used here.

The kang incubation method in the north has simple equipment and large incubation capacity, which is very suitable for large-scale breeding needs. If the technology is skilled, the hatching rate is between 80% and 90%, which is comparable to modern electric incubation methods. An ordinary seven-fire cave kang incubation workshop can enter 2,600 eggs at a time, and as many as 15,000 eggs can be hatched every month. Even if it is to be expanded, it is fairly simple and requires almost no modern equipment and materials, which is more suitable for incubators than the thermal insulation of fired adobe bricks.

In the past, maybe the farm manager would have worried about where to find so many eggs, but now there is no such problem, and after several years of development, chickens and eggs have already formed a cycle, and there is an endless stream. More up here close to the Monkey Island Port, merchants coming and going, dock workers. Coupled with the tens of thousands of workers in the development zone, the demand for work is huge. In the past two years, the surrounding area has already formed a related industrial chain, farms, slaughterhouses one after another, even if this farm is short of chicken seedlings, in other places can also be easily purchased.

"Steward Zhu, what is the total number of poultry and livestock on this farm now?" Geng Jingzhong asked the farm steward who was carefully accompanying him.

Steward Zhu had been waiting for Geng Jingzhong to ask a question, this farm was the largest under the palace, and he would definitely be promoted if he did a good job, not to mention that of course he had to behave well in front of the prince now. "Back to the prince, our No. 13 farm now raises a total of three kinds of poultry: chickens, ducks and geese, about 60,000 chickens, 30,000 ducks, and 1,000 geese, as for domestic animals, the number is much less, only 3,000 pigs, 600 cattle, and 2,000 heads. Every month 25,000 poultry, 400 pigs, and 300 pigs were to be provided to the barracks. ”

Geng Jingzhong nodded after hearing this, and calculated silently in his heart, there are a total of fifteen farms, and the poultry and livestock provided here can meet the consumption of all soldiers for a week, and it seems that there is really no need to worry about this aspect. Geng Jingzhong also thought that the 4,000 soldiers scattered in various provinces in Fujian were all purchased locally, and the nearly 7,000 soldiers of the Jane Eyre Army in Luzon were also supplied locally, which reduced this part of the pressure, no wonder these farms still had the spare power to sell to the outside world! "Okay, you're doing well!"

After seeing the hatchery, then there is the chicken coop, the chicken coop here is also quite simple, that is, rows of low wooden small shacks, but at the moment there is not a single chicken in the chicken coop, they have been put on the hill to eat! These chickens are all free-range, and although there are not so many grass insects in the mountains for so many chickens to eat, these chickens are not easy to get sick when they are scattered. In addition, there is a special feeding trough for chickens on the hillside in the morning, and the chicken food will be poured into it regularly every day.

The coop still looks relatively clean, and you can see that the ground has just been sprinkled with water, and there is a smell of lime. "Prince, please see, the chicken manure will be cleaned regularly every day, and then sprinkled with lime water for disinfection, which is also what you said before, which can prevent chickens from getting sick. Sure enough, after this measure was taken by the farms, the poultry and livestock rarely got sick! ”

"Oh, well, it seems like I mentioned that a long time ago! However, is there any fish farming here? Geng Jingzhong asked again. Geng Jingzhong knows that chickens have a short digestive tract, and the feces they excrete also contain many nutrients. In later generations, there was a kind of circular agriculture that raised chickens next to the fish pond and fed the fish with chicken manure.

"Back to the prince, no!" Steward Zhu immediately replied, but he chuckled in his heart.

"I see that there is a river here, and you can use a net to block the Minjiang estuary and raise fish in it, and these chicken manure can be used to raise fish. Also, although this thing is disgusting, it can also be used to feed pigs after fermentation, and pigs should still love to eat. Geng Jingzhong said with a smile. However, if there is enough feed now, it is okay not to use this thing, which is indeed a bit disgusting. ”

Steward Zhu hurriedly said yes, no matter what, he still has to try it when he goes back, if it is feasible, he will do what the prince said, and he may also get a promotion capital. The group continued to walk forward, and soon reached the duck shed again. Ducks are much more effective than chickens in poultry farming, which are omnivorous and self-foraging in grazing, tolerant of rough feeding, and have a high feed conversion rate. In his previous life, there were people in Geng Jingzhong's hometown who raised ducks in the rice fields and let the ducks forage in the rice fields. Not only can you use snails, small fish and shrimp in the rice fields. It also exterminates pests and weeds. If you wait for the rice in the paddy field to be harvested, then drive the ducks in to clear the field. Eating the grain and sporadic rice left in the field is much more convenient and thorough than manual cleaning. There is also a nice term called "duck rice farming" in the Wa country, which is a pure natural rice cultivation method of retro flow.

The duck shed is located next to the river bay, and a bamboo fence separates the water bay from the river, and there is a sluice gate that can be opened and closed, so that the ducks do not run away on their own. The reeds are thick, the river is rich in nutrients, and there are plenty of aquatic animals such as snails, which ducks love to eat, along the bay. Workers in charge of raising ducks. Every day, I go out to herd ducks, and by the way, I also catch snails and mussel shells, which are smashed and used as feed for ducks.

"Lord be careful!" Steward Zhu suddenly reminded him. It turned out that a duck egg appeared under Geng Jingzhong's feet, and it must have been a disobedient duck who laid the egg on this riverbank!

"Don't stomp on it!" After Geng Jingzhong reacted, he immediately said to the guards behind him.

"Everyone, be careful, especially don't step on the grass in this riverbank. The ducks probably lay their eggs in it, and it wasn't until late afternoon that the workers made their rounds to pick them up. Steward Zhu reminded loudly.

"Fortunately, there is this river here, and ducks and geese have to have a water surface, and the breeding conditions are restricted. This salted duck egg is also a favorite dish of this king, do you know how to pickle it here? ”

"Back to the prince. Yes, the farm now receives 5,000 duck eggs a day, and so many duck eggs are pickled into salted eggs and preserved eggs! After all, this fresh Yandan is not as delicious as eggs, but after being made into salted eggs and preserved eggs, there are many people who love to eat them, and the barracks have to pull them every half a month, and they take away seventy or eighty thousand each time. Steward Zhu said with a smile. Does the prince like to eat salted duck eggs? This is important news, you can pick some good salted duck eggs and send them to the palace, which is a great thing!

"Tsk, poultry is growing fast, and it would be nice if pigs could have such a high reproductive efficiency." Geng Jingzhong sighed.

"Pig breeding is also good, and now more and more piglets are being born. Sows can give birth to 20 piglets a year, and generally can stay 15 or 6, after three years of development, the sow alone now leaves 400, and every month there are piglets born, and the subordinates are also ready to expand the scale of the pig farm! Steward Zhu immediately responded.

"Hmm." Geng Jingzhong nodded again, but this time he didn't say much.

As he was talking, everyone had come to the place where the livestock were raised, and the most of them here were pigs. The thirteen farms are all filled with this kind of big black pig in front of them. As the saying goes, "every family has a black pig", this kind of black pig is a kind of Chenghua pig, with black hair all over the body, short limbs, and fat body. In the past, farmers did not have enough grain to raise pigs, only fed pigweed, the growth was too slow, fattening a pig of about 200 catties took 24 months to be slaughtered, compared with the later generations of pigs only six or seven months is really uneconomical. But now on the farm, in addition to pigweed, there are many other omnivorous, sweet potatoes and corn are fed, and the growth is much faster, basically it can grow to more than 200 catties a year, and it can be slaughtered!

"This pig's life is really free, and the surrounding environmental sanitation is also good." Geng Jingzhong didn't speak, but the Gu Ping guards behind him talked in a whisper.

"Of course!" Suddenly, Geng Jingzhong's voice sounded in their ears. "Animals also have psychological pressure, don't think pigs like dirty and smelly environments. They have a good life, so that they can get less sick, grow faster, and have good meat. This farm is doing the right thing! ”

"Thank you for your compliment!" Steward Zhu replied with a smile.

In front, it's the bullpen. In addition to pigs, cattle are also a large herd of livestock in the feedlot. Although the number is a little less, the size of the cattle is large, and there are many buffaloes and cattle here. The cattle in the cattle farm are mainly used as animal power, and at present they are mainly used for supply and use on the Luzon side, not for killing and eating. The cattle in the cattle farm are resting at this time, it is now afternoon, the weather is hot, and several agricultural workers are sprinkling water around the cattle shed to cool down. These cattle are very well cared for because they have to bear the heavy task of road transportation every day, not only adding concentrate every day, but also ensuring that they are given adequate rest.

"There are a lot of cattle," Mr. Geng said. (To be continued......)
