In March and April, many crops can be planted in Shannan Province, and the spring ploughing in the north of the land has also begun to be busy, and when they will be assigned to the past seeds have been planted, whether it is good or bad, just wait to see the results, as long as these plantings are not adapted to the soil and water, can be normal seedlings, with the level of agricultural children or agricultural students, they can basically ensure their survival, and achieve a certain harvest.

Sun Xiangfu's work is the busiest of the three planting areas, and he doesn't have to worry about the few field crops with strong adaptability, but many special crops need to be selected according to local conditions and planted in the wasteland.

"The ghost weather here is too hot, teacher, you can rest for a while and drink some mung bean soup!" Li Tai, who was sweating all over, handed a bowl of chilled mung bean soup to Sun Xiangfudao, who had recently followed Sun Xiangfu to participate in the farming, but he had lost some weight.

Opening up plantations in the mountains and forests of Lingnan is much more difficult than Sun Xiangfu imagined, not to mention the hot climate, inexhaustible mosquitoes, insects, rats and ants, just those beasts that will emerge from time to time to attack people, you need to often organize people to hunt, the key is that these things are endless, after killing a batch, there will be another one, forcing Sun Xiangfu to enlarge the move, after delineating the range, set fire to the ground.

However, setting fire in the primeval deep forest, must be very careful, for all the subordinates to clean out the location of the fire belt, he needs to personally check, eliminate the danger, some places are not at ease, when checking, he will also do it himself, strengthen the repair.

"Doing things will not be simple, especially agricultural work, like our current alley, to open up all the plantations, I am afraid that it will take several years, we have to find a way, find another way."

Sun Xiangfu dropped the shovel for digging the soil, took the mung bean soup handed over by Li Tai and poured it down, in the hot weather environment of Lingnan, if you don't replenish the heatstroke drink in time, it is easy to fall into a heat stroke coma.

"The main reason is that we don't have enough manpower, if we mobilize one or two million people to work together like we did when we were building a field in Shannan Road, it will be quick." Li Tai used a spoon to fill Sun Xiangfu's bowl with mung bean soup from the large bucket of mung bean soup again.

"There are more industries in Lingnan, and the people have their own things to do, so if they have to let them put down everything and help us work, the price will be too great, and I have been thinking about it for the past few days, perhaps, I should go to Yunnan." When it came to the second bowl, Sun Xiangfu no longer drank so violently, and said while taking a small sip.

Li Tai asked a little puzzled, "What are you doing in Yunnan?" ”

Sun Xiangfu replied, "The weather over there is like spring all year round, and the crops that can be planted here can also be planted over there, and this year, a large number of terraces have begun to be opened over there, in fact, there are a lot of crops, we can put the plantation on their side, if you count it, the manpower over there is much more abundant than that here in Lingnan." ”

Now in Yunnan, the road is not easy to walk, and there is a shortage of food, it is necessary to introduce high-yield crops there as soon as possible and teach the local people to plant, after all, the Yunnan tribes plus some newly surrendered tribes in the southern forest area of the south, but there are more than 2 million people.

"Didn't you already send a lot of agricultural students over there before, send someone to send some seeds, and then tell them about the growth habits of these crops, so that they can seed their own seeds?" In Li Tai's words, some did not want Sun Xiangfu to leave Lingnan.

"These new crops, that is, the children of the farmer's family, have never seen it, let alone those agricultural students, so, I still have to go to see, here, after the sisal and rubber trees are planted, I put the second small here to take care of it, although he usually talks little, but the planting level and comprehension are still very high, as for other crops, they are not urgently needed, we can take our time, anyway, I will go to Yunnan over there, that is, make overall arrangements, and return in a few days." After Sun Xiangfu finished drinking the mung bean soup, he put the bowl down.

The weather in Yunnan, especially in the south area, is very suitable for planting a lot of crops, basically do not need to catch up with the season, like rubber trees, planted in the hotter weather along the coast, it may be better, anyway, there are many seeds, and the effect may be better if you try to plant in several places.

"Then, I'll inform the people to prepare the fast boat, you have to come back quickly, here, after the land to be developed is burned and the surrounding beasts are driven away, we will start to build a house, the 'fortress-style diversified farming and living in one' farm you said, the design is very complicated, it is better for you to come and watch it yourself."

The so-called fortress-type diversified farming and living integrated farm is a large-scale civil engineering building designed by Sun Xiangfu according to the special environment of Lingnan now, drawing on the surrounding houses and watchtowers of Lingnan in later generations, which is convenient for everyone to plant and breed, and can ensure the safety and comfort of everyone's living quarters.

After it is completed, it can be used as a unit in the village, concentrated living in dozens to hundreds of households, and the design of the surrounding house and watchtowers makes it difficult to break through once it closes the gate, even if the bandits and bandits want to enter, not to mention those poisonous snakes and beasts.

In fact, similar buildings began in the Sui and Tang dynasties of the two Jin Dynasty, but Sun Xiangfu added a lot of modern concepts to it, so that it can exist more safely in the deep mountains and old forests, and at the same time, it is also more convenient for production.

First of all, he had to choose a good site, not only in the middle of the farmland, with easy access to water and a wide view, but also to rule out the possibility of being hit by flash floods or mudslides.

Secondly, all the entrances and exits, even when they are open during the day, also use a maze-like whirlwind entrance and exit, even if there are beasts who want to come in when the gate is not closed during the day, it is easy to put in this unique design of the doorway, which is some of the architectural art of watchtowers.

It also has a lot of watchtower features, such as the height of the first floor will be very high, and, do not live in people, can be used to raise chickens and ducks, cattle and sheep and other poultry and livestock, only need to lead a water into the sand filter pool in the corner of the wall, clean water filtered from the sand into the yard, not only can be used for chickens, ducks, cattle and sheep livestock to drink, but also can be used to clean the residence of these poultry and livestock, according to the frequency of comparison of cleaning, there is a ceiling height space of up to five meters, and to the interior is basically open to ventilation, generally will not have much smell, after all, The scale of farming here is not very large, it is just for the people living in the fenced houses to eat themselves, or to use when farming.

Clean up the sewage of a livestock shed, as well as the manure of cattle, sheep, chickens and ducks, will flow directly into the large septic tank dug before along a drainage channel with a high and low design for drainage, and the sewage system upstairs is also connected to the septic tank.

Moreover, people do not live on the second floor, but on the third floor, because the second floor is a warehouse for agricultural tools or grain.

From the first floor to the second floor, it is not a staircase, it is a large slope for board trucks to pass around, the weather in Lingnan is humid, especially when the south wind is blowing, you can not put the grain crops on the first floor, or store them close to the ground, which will quickly become moldy.

Even on the second floor, it is placed on a wooden shelf, under which are placed moisture-proof lime bags, and then two or three layers of moisture-proof are enclosed with hay mats.

The third floor is the place where people live, with a thick tile roof, and large windows on both sides of the interior and outside, which is not only ventilated and cool, but will not be affected by the smell of the poultry and livestock room on the first floor, and is also drier, and people will be healthier if they live in such a place for a long time. Moreover, after the place is higher, there will be fewer mosquitoes, and it will be easier to kill mosquitoes and eliminate mosquitoes.

At that time, everyone only needs to sit at home, you can condescendingly, looking down on the fields distributed around the house, there are people, or there are wild beasts want to get close, you can see from a distance, and you can also see the crop growth through the contrast of color, height and other aspects, it can be described as an excellent field view house.

In the middle of the enclosure is a large circular drying field, as well as a leisure sports area, usually put some solar pots, boil drinking water, dry firewood or something, when the farm is busy, it will be used to dry crops, such a building is built, basically can provide most of the living needs of all the residents living here, and then equipped with a certain weapon to hunt beasts, it is proper.

This kind of centralized living can also allow them to concentrate together for hunting and farming, and the degree of danger is much lower, and it is much safer than many of the original households who live outside the city and live in scattered timber frame houses, and the degree of comfort and cleanliness is not at the same level at all, almost reaching the best degree of this era, in the environment of Lingnan, except for living in the big city.

After all, those who live in the city are all engaged in business and work for a living, and in this society, it is impossible for all people to go to business and industry, and agricultural production is the basic guarantee for everyone's survival.

After the prototype of the first plantation basically came out, Sun Xiangfu took some seeds and boarded the ship to Jiaozhi, these buildings can maintain the long-term peace and stability of the people in the Lingnan area, Feng Ang knows its significance, and also explained the truth to Li Tai.

In the future, it will bloom all over Yeongnam Province like the fields of Shannan Province, and gradually develop this land into a good place where human beings can live, produce stable output, and make people safe and comfortable.

Now the Lingnan shipyard here to make boats, in the case of good sea conditions, can not travel more than 500 miles a day, that is not called a fast boat, because this side to Jiaozhi County, Ninan County, under their frequent exchanges, has become more and more scientific, so, less than 2,000 miles of voyage, day and night sailing, three days to arrive, with the map of later generations, the fleet, just from Guangzhou Bay, from the coast of Guangxi, to Vietnam Ha Long Bay landing.

Sun Xiangfu did not take the elephant directly to Yunnan, because the area where he landed is almost the most suitable area for planting trees in the whole of Asia, and the rubber trees, snake mulberry trees, cocoa trees, and the tree species that were later named Brazil nut trees can be planted here, but because of the limited manpower, Sun Xiangfu just surveyed some good sites by the way, and had to put it down, and when he returned, he could let Shelong send some people to come here to do development.

It was not until mid-April that Li Chengqian took a delegation of the Western Regions countries that owed a debt to the Tang Dynasty to board a ship from Weinan and set off for the south, and Sun Xiangfu arrived at Dali City, the seat of governance in Yunnan County.

In fact, it is much worse than Lingnan, which has been rapidly developed in recent years, because, although the people here are not inferior to Lingnan in terms of sinicization, they do not have as many industries as Lingnan, and they do not have as frequent communication with the outside world as Lingnan in recent years, and the economic strength does not allow them to be like Feng An, throwing money to invite people to teach Chinese, teaching production knowledge, and engaging in universal medical security, etc., that is, even Dali City and Shelong have been tossed for two or three years, and they have only built a rough idea. It's still far from being repaired!
