The prince transferred Peach's son Tang Jun and Zhu Yuan, the eldest son of Zhu Medical Officer, to the greenhouse as the person in charge. Both of them grew up fiddling with traditional Chinese medicine, Tang Jun's family once had a medicine garden, and Zhu Yuan was also in charge of the medicine garden in the house, and the medicinal materials in this medicine garden were prepared for the pharmacy in the house. And they also know very well about serving vegetables, and the tempers of the two are also compatible. Tang Jun's personality is very similar to Tian Liang, and he doesn't like to talk. After he entered the house, he has been working as an errand in the medicine garden, vegetable garden, and flower garden, and he is very diligent in his work, and the prince saved him, and his gratitude is unforgettable. Wang Ye and Fu Jin have already made the decision to marry Liu Er, the maid who served Mr. Chen and Mrs. Chen, and the two have met and are very satisfied with each other, and the previous fiancée withdrew from the marriage because of his lawsuit. Zhu Yuan has always been an errand boy in the house, he is the head of the medicine garden, the eldest son of Doctor Zhu, and naturally the son of Mama Zheng.

The prince has always been steady and steady. The four King Kong guards took turns to follow the prince to guard, among which Tian Liang stayed by the prince's side all day long, and Ma Ping never left an inch. In less than half a month, a glass house that the Qing Dynasty had never seen before stood in Nanwaifu. The next is to take the soil and raise seedlings, the prince not only brought back all kinds of grain, fruit trees, flowers, herbs and other seeds, but also brought back a large number of seedling trays, the seedling trays are rectangular or square sixty or seventy centimeters long thick plastic with round, square pits of plastic seedling trays, is a combination of plastic parts that can be disassembled. It's very convenient to use. When raising seedlings, the seedling trays are combined, and each pit is filled with soil mixed with fertilizer, and then the seeds that are cultivated and germinated in the nutrient solution are planted into the pit of the seedling tray, and then watered according to the water required by vegetables or flowers. There are water seepage holes under the seedling tray, which will not let the water blister and rot the seeds. When the seedlings are long enough to be transplanted, the tray is dismantled, and the seedlings in each pit are transplanted with enough soil. Basically, there is no need to slow down the seedlings, and they will survive directly. Although the price of this set of equipment is expensive, the good thing is that the seedling raising effect is quite good. This is an advanced equipment that people in the Qing Dynasty could not even imagine, and it is much more advanced than the exotic paper tube seedling raising. The prince selected all the seeds that needed to be raised when he brought back, and began to raise seedlings when the greenhouse was completed. There are also a lot of books on greenhouse cultivation techniques brought back by the prince, and if you don't understand, you can also ask the books for advice.

Ma Ping saw the greenhouse drawings designed by Mr. Zhong, and was very embarrassed, that is accurate, that is called strict, is it as rough as the drawings he drew in the past? In particular, those technical terms in the description of the drawings gave Ma Ping a feeling of seeing a giant spirit.

I thought that the tire car was already very sophisticated and out of line, but I didn't expect that the greenhouse for seedlings would be even more shocking. Tian Liang commanded the soldiers to install the small aluminum alloy frames inlaid with glass one by one on top of the large frame, which were tightly and neatly organized! It's just as bright inside and outside, but it's much hotter inside, as if there's no cover.

Where is this where the seedlings are raised? It's a place to enjoy Cheongboup! How much silver does this cost? Ma Ping is convinced by the prince! I thought that the prince was going to grow some vegetables on his Zhuangzi, but who would have thought that he would invest so much and build such a sophisticated vegetable greenhouse. The emperor said that the prince wanted to add silver to the treasury, and he didn't want the emperor to give the capital, but when he saw this greenhouse, he was very shocked, why was he so stupid? If nothing is done, is it worth investing so much? In the future, if the emperor's relatives and ministers all see the prince's political achievements, won't they be jealous? Isn't that evidence of a high level of merit? Han Xin and Yue Fei all ended up well because of too much credit, what is this picture? Ma Ping couldn't persuade or dare to persuade, so he could only worry about him silently.

The prince handed over the aftermath to Tang Jun and Zhu Yuan, the kang in the greenhouse, the ventilation flue for burning the kang, the soil for seedlings, the quilt for keeping the greenhouse warm in winter, and so on. He wants to experience Tang Jun and Zhu Yuan's ability to stand alone.

According to the book "Greenhouse Seedlings" that he brought back from a foreign land, Wang Ye told Tang Jun and Zhu Yuan the detailed process of how to raise seedlings in the greenhouse, although it was not particularly profound, nor was it any knowledge of the Qing Dynasty.

The glass greenhouse for seedling cultivation was propped up, and the prince took advantage of the victory to pursue, and then built a glass greenhouse of the same size for cultivating flowers. He was going to erect all the greenhouses he had brought back from the foreign land in the relatively wide field of Nanwaifu. But at the moment, only these two can be built, and he will also build a few semi-underground windproof and frost-resistant plastic film greenhouses for growing vegetables.

The temperature in the greenhouse is several degrees higher than that in the open air, and you can grow southern vegetables, which is the main purpose of the prince. The soil here is relatively fertile, the soil layer is deep, the irrigation is convenient, and the ventilation conditions are relatively good. The direction is also east-west, which ensures the full lighting and has a better heating and thermal insulation effect. Different from the alloy greenhouse, the plastic film greenhouse can reach a length of 150 meters, a width of 10 meters, and a depth of one and a half meters.

The construction of the wall is divided into two parts: the construction of the back wall and the construction of the side wall. The construction method of the back wall is basically the same as that of the glass greenhouse, that is, the frame is very different from the glass greenhouse. At either end of the side is a curved wall that is lower and lower to the south by the back wall. Then the loess is packed in woven bags and tamped and built from the bottom of the pit. The width of the masonry below the ground is two meters, the part above the ground is six meters, the top is two meters, and the height from the ground is two meters and seventy meters. In this way, the temperature in the shed can be guaranteed, and the soil slope can be formed on the north side of the shed to reduce the damage caused by strong winds to the greenhouse. The junction of the side and back walls is sealed with cement. After the wall reaches thickness, no matter how low the outside temperature is, it has no effect on the inside of the shed. Not only does it not dissipate heat, but it also absorbs heat. The temperature in the greenhouse can reach 28 to 30 degrees Celsius during the day, which is the most suitable temperature for growing vegetables.

The next is to build a column, beam and keel of the greenhouse skeleton structure, in which the keel structure is composed of steel keel and plastic pipes, play a supporting role in the shed film, to build an arch, the shed film plays the role of a fixed seat and a light vertical shot greenhouse. Then there is the mulching film......

Mr. Zhong gave a rough estimate that in such a large greenhouse, four crops of vegetables can be planted in a year, with a yield of 6,000 catties per mu, and an annual output of vegetables in a greenhouse can reach more than 30,000 catties. If you grow out-of-season vegetables, the economic benefits are even higher.

Don't look at Tang Jun and Zhu Yuan's different personalities, they have a common feature in doing things on errands, they are both neat and capable. There was no excuse for the sudden burden, and the new subordinates who led them took action. The first thing is, of course, to pull the soil, they borrowed a newly installed tire car from Tian Liang, and went to Xishan with their own soldiers to pull the soil. There were not many households in the western mountains of that meeting, and there were few crops, and there were many mountains with many trees and the dung of birds and beasts. The leaves fall and rot year after year, and the soil is quite fertile. The prince brought back the bundles of woven bags for them to use to hold the fertile soil of Xishan, a bag of soil more than 100 catties, but the humus on the surface was loaded back, and there was no need to dig up the soil layer, so it would not make the soil sandy. The soldiers pulled the soil back, mixed a certain proportion of the soil from Nanwaifu according to the prince's requirements, and poured it into the glass greenhouse and plastic film greenhouse, without fertilizing at all. Then he planted the tomatoes, strawberries, sand melons, purple cabbage, broccoli, oily lettuce and other fruits and vegetables that were not available in the Qing Dynasty taught to him by the prince according to the separate nursery ponds. In addition to fruits and vegetables, saplings, flower seedlings, spice seedlings, herb seedlings, etc., each species is cultivated in a seedling pond. The wooden sign of the variety is written on the nail, so you don't have to forget what kind of seedling it is.

The semi-underground windproof and frost-proof plastic film greenhouse is also planted with common vegetables such as eggplant, beans, celery, rape, cabbage and radish, as well as amaranth, Chinese cabbage, water spinach, lettuce, taro, mustard, sharp pepper, bell pepper and other vegetables that are not common in Beijing. It's doing experiments. If Tang Jun didn't understand, he asked the prince for advice, and the prince read books to understand when he was not in the house. Many people jokingly called Tang Jun and Zhu Yuan "Tang Pengchang" and "Zhu Pengchang". They are all the proud protégés of the prince, and they are the first recipients of the skills that the prince has learned from foreign lands.

The method of raising seedlings is to soak the seeds in warm water for one hour, then remove the water, put them in a clean container, cover them with a wet towel, change the warm water twice a day to wash them, and when the seeds germinate, then plant them in the soil at a distance of 15 centimeters, and water them to grow into seedlings.

The seedling tray of the prince is divided into many types such as vegetable seedling raising and rice seedling raising. It is all plastic frames, and it is an assembly equipment that can be disassembled and combined. It's clean and easy to use. The technology was taught to the two shed chiefs, and the seedling tray was also handed over to the two greenhouse chiefs, who liked the two shed chiefs badly, for fear of knocking and touching the ground. It's too late for rice, it's already past the rice planting season, so we can only wait until next year.

Seeing the prince doing what he wanted to do so seriously, Ma Ping was very moved. In the case of an uncertain future, so much money has been invested to build such a sophisticated ice cellar and greenhouse, and so many new starting point equipment have been purchased, no one dares to think about it. Take your own money to make money for the emperor, what kind of open-minded person can do this?

Ma Ping felt that the prince came back as if he was a different person, not only cheerful and talkative, but also more approachable, and seemed to have mastered a lot of knowledge that the Qing people did not have.

The prince's affairs are approved by the emperor, and the emperor's trust in the prince is more intimate than which royal family relatives are closer, and more trusted than any minister in the court, and it is right to follow the prince.

After that, Ma Ping followed the prince and kept him alone.

Ice cellars and greenhouses have always been the facilities that have been close to the heart of the prince. It would have been as hard for him to move forward without these two facilities as it would have been without his legs, and now he had finally gotten his wish.

After the completion of two greenhouses, an ice cellar, and a plastic film greenhouse, the prince gave a certain reward to all those who participated in the construction of this infrastructure. Twenty taels of silver for each person, and three days off.

The next thing is the decoration of the three kitchenettes of Fujin, Yun'er, and Mrs. Chen. There is no word decoration in the Qing Dynasty, and Ma Ping is also a little confused about the decoration plan provided by Tian Liang, what is tile and mosaic? He didn't dare to stick out his head in this matter, and he didn't know what the prince meant. A well-used kitchen, clean and clean, why decorate? But he didn't want to and didn't dare to stop the prince, and he didn't know a lot about the prince, so he just learned.

Tian Liang was responsible for preparing the materials and successively sending the building materials needed for the small kitchen from the buildings, platforms, pavilions, and offices in the garden to the three construction sites. It wasn't until Tian Liang showed Ma Ping the decoration drawings he designed and the decoration renderings drawn by Yun'er that Ma Ping understood why the kitchen should be renovated. I also learned which is a tile and which is a mosaic among the building materials that the soldiers have brought one after another.

This prince is amazing, he bought so many new things to decorate the kitchen, and he spent a lot of money! Ma Ping admired it very much. The heart said, how much do these white tiles cost? It's not just three or five pieces. Shibei was impressed for three days. In the future, he must follow the prince, and if he doesn't want anything else, he will be able to eat for a lifetime with his knowledge. There is also that Tian Liang, I don't know how much that ability is, he has grown bean sprouts to a big day, and he is busy all day long, and he doesn't see a trace of panic. This person will definitely develop in the future! The prince has vision, so many guards just pick him out and cultivate, this is called discernment.

Ma Ping has been following the prince around the two construction sites, and designing the imperial tomb is already a big skill, but in these two facilities, he feels that he is as shallow as a child who has just opened his studies in front of Hanlin scholars. In fact, he was thinking a little too much. Ancient technology and the 21st century are completely different systems. For example, those glorious buildings in ancient times may not be able to be designed by modern architectural doctors and experts.

"I said, Master Chen, why does the disciple think that our knowledge is the same as that of the prince and Tian guards? It seems that other people's ones are more practical. ”

"The knowledge of the place where the prince went is very different from our Daqing Dynasty, even Yun'er doesn't seem to know about painting, what to raise children to feed scientifically, I used to boast of a little knowledge, but now I look at it, it's pitiful."

"Don't think like that, others don't know your knowledge, but the disciple understands how deeply."

"Don't defy me, it's better to learn a little more from the prince."

"The prince is really hidden, the disciple has always thought that the prince was born in the military, and he doesn't know these things about the people at all, not to mention that he is in a high position, the prince's age is enough to live, the child has so many military exploits, and there are two rescues, and he can still do this for the ...... of the country."

"Yes, the prince is open-minded."
