Da Qin: Comparing his sons, Ying Zheng was sour.

[After talking about the various comparative research teams under the Tianshi group, Prince Fusu continued: "The second group, the fertilizer group!"].

["The so-called fertilizer, the material of the acres of fertile land!"]

["Xu Zi is proficient in farming, so he naturally knows that there is a difference between fertile and barren acres of land. "】

["Among them, the grain yield per mu is higher in the acres of fertile land, and the grain yield per mu is lower in the acres of poor land. "】

["But if you use certain external aids, you can make the land change from barren to fertile. "】

[For example, Gu once saw in the book that if you use plant ash to assist farming, you can make the land more fertile and the yield of grain per mu can also increase. "】

["Similarly, weeds in the field also have the effect of promoting the growth of millet after decaying. "】

["And things like plant ash, decaying weeds, and other things that can make the land fertile, promote the growth of food, and increase yields, are collectively called fertilizers. "】

["So in addition to grass ash and decaying weeds, are there any other fertilizers that can make the land fertile, promote food growth, and increase yield?"]

["Lone thinks that there should be, but what specific things can be used as fertilizer to make the land fertile, promote food growth, and increase production, that is the problem that the children of farmers in the fertilizer group need to study. "】

["In the fertilizer group, a research team selects something that is likely to be used as fertilizer. "】

["The specific number of research teams under the fertilizer group is up to Xu Zi to decide. "】

["Lone's only requirement is that any research team must adopt a comparative research method of two by two, and the daily cultivation matters must also be recorded in detail. "】

["In this way, we can clearly see the difference between the acres of land that uses fertilizer and the acres of land that does not use fertilizer. "】

["Group 3: Farming Methods Group!"]

["Can the current cultivation method of acres of land in the world be improved?"]

["For example, if I use different farming tools to cultivate, will the cultivation efficiency be different?"]

["For example, the same four acres of land, two of which are planted with the same wheat and soybean every year. "】

["The wheat and soybean on the acres of the other two fields are planted in turn. "】

["So will the cultivation output of this fixed planting method and the alternating planting method be different?"]

["There are other farming methods imaginable, which are different from the current farming methods, you can give it a try."] "】

["I am not afraid of all trial and error, but as long as we experiment with a new farming method, we can bring higher farming efficiency and more farming output than the existing farming method. "】

["Then all the previous failed attempts will be worth it!"]

["It is also a research team that chooses a new farming method for research, and must also use a comparative research method of two by two, and at the same time record the daily cultivation matters in detail. "】

["And under the cultivation method group, how many research teams should be set up, this is also up to Xu Zi to decide. "】

["At present, under the Department of Agriculture, Lone only thinks of dividing these three groups for the time being. "】

["If Xu Zi finds that there should be another research team, then Xu Zi can also decide for himself, and there is no need to ask Yu Gu again. "】

["The Ministry of Agriculture has a second division, called the Forestry Division. "】

["The division is mainly responsible for researching and optimizing the specific planting methods of various fruit trees. "】

["How many research groups and research teams should be set up under the Division."] "】

["After this, it is up to Xu Zi to consult with other peasant children and decide for himself. "】

["Lone doesn't know much about fruit tree planting, so I won't say much. "】

["The requirement is still the same one, all research teams and research teams must adopt a comparative study method of two-by-two, and the daily cultivation matters must also be recorded in detail."] "】

["In this way, we can see the differences between different fruit trees and different planting methods, and we can continuously improve them on a better basis. "】

["The Ministry of Agriculture has a third department, called the Animal Husbandry Department. "】

["The division is mainly responsible for researching and optimizing the breeding methods of various poultry and livestock. "】

[For example, which of the current population of poultry and livestock are the easiest to raise, require the least amount of feed, or are the cheapest. "】

"For example, how can we make these poultry and livestock reproduce faster, grow more meat, and so on. "】

["These are the contents that the research team and the research team under the Animal Husbandry Department need to study. "】

["It is also specific how many research groups and research teams should be established under the Division."] "】

["After this, it is also up to Xu Zi to discuss with other peasant children, and then decide for himself. "】

["Gu doesn't know much about poultry and livestock, so I won't say more. "】

["In the same way, all research teams and research teams of the Animal Husbandry Division must adopt a comparative study method of two and two, and the daily cultivation matters must also be recorded in detail. "】

["The reason is also mentioned above, this comparative research method is helpful to observe the differences and summarize the improvements. "】

["The Ministry of Agriculture has a fourth division, called the Jianghe Division. "】

["The department is mainly responsible for researching and optimizing the specific breeding methods of various fish, shrimp, crabs and other aquatic products in rivers and lakes. "】

【" ̈~ For example, among the current fish, shrimp, crab and other aquatic river fresh, which fish, shrimp, crab are the easiest to farm, which requires the least amount of energy, or the easiest to catch. "】

["For example, what things can be fed to make these fish, shrimp, and crabs reproduce faster, and so on. "】

["These are the contents that the research team and research team under the Jianghe Division need to study. "】

["It is also specific how many research groups and research teams should be established under the Division."] "】

["After this, it is also up to Xu Zi to discuss with other peasant children, and then decide for himself. "】

["Lone doesn't know much about fish, shrimp, crabs and other aquatic river fresh, so I won't say more. "】

["The research requirements for each research group and research team under the River Division are also the same as those of the above divisions. "】

["The Ministry of Agriculture has set up the Fifth Division, known as the Textile Division. "】

["The division is mainly responsible for researching and optimizing the current weaving methods of silk and linen, improving the current textile efficiency of silk and linen, and looking for other clothing that can be like silk and linen. "】

["Under the division, how many research groups and research teams should be set up, and the same Xu Zi will decide on his own after that. "】

["The research requirements for the Division's research teams and research teams are the same as those for the Divisions mentioned above."] "Beggar]

["The Ministry of Agriculture has a sixth division, called the Hundred Herbs Division, which takes the meaning of Shennong to taste the herbs. "】

["The department is mainly responsible for researching what other things can be popularized, planted and eaten on a large scale in addition to the five staple foods of rice, millet, millet, wheat and soybean, as well as the five vegetables of sunflower, weed, shallot, onion and leek. "】

["In the future, the various crops brought back by the Foreign Merchants Division of the Ministry of Household Affairs from all over the Tiannan and Haibei regions, as well as their seeds, are one of the contents of the research of the Baicao Division. "】

["The number of research teams and research teams that the division should set up is also up to Xu Zi to decide. "】

["The research requirements for the Division's research teams and research teams are the same as those for the Divisions."] "】

["The above is the six divisions of the Ministry of Agriculture. "】

["Some are simple, and there may also be some omissions in thought, and I ask Xu Zi to check and fill in the gaps. "】.
