    Li Zhe was very satisfied after hurriedly handling some things in modern times and gained a lot.

    In fact, in Li Zhe's current position, there is no need to be so anxious about many things. Silence and slow penetration are the best. The initial financial constraints were originally a big problem, but Li Zhe issued this order with a belt.  The incredible trick was solved, and after that, the development of the power entered a broad road.

    In this modern, rudimentary information society, the most troublesome thing is not the difficulty of running a business, but the various overt and covert attacks and spying.  For example, the issue of the Clothes and Belts Order has attracted the secret attention of many people. I don¡¯t know how many people are secretly looking for the powerful tomb-robbing organization behind him. Even if Li Dong is a partner on the surface, why don¡¯t they want to abandon it?  Are Li Zhe going to cooperate with this group of people?  No one has too much money, and this kind of thing is always hard to guard against.

    But fortunately, this organization actually does not exist at all!  No one can find any information about them, so this makes many people worried.

    Nowadays, most people are still in awe of rules. They are always somewhat restrained and will not easily choose to make things worse. And those who want to make things worse do not have to go directly until they see enough benefits.  But the people at the top, who are powerful enough to violate the rules, are not interested in getting involved with a nobody like Li Zhe. This is why Li Zhe is still safe and sound until now.  In fact, whether it was reselling antiques or setting up shop in Hong Kong, Li Zhe didn't make a huge upfront effort. It's just that this kind of thing is normal for business people and is really not worth mentioning.

    Therefore, Li Zhe can be leisurely and comfortable in modern time and space.  This is completely different from the existence of a truly naked powerful society in ancient times.

    Now in the time and space of the Three Kingdoms, the issue that Li Zhe needs to pay attention to - the domestication of poultry and livestock needs to be officially put on the agenda.

    In this time and space of the Three Kingdoms, the vegetation is so lush, which actually has an innate advantage in the breeding industry.  It¡¯s just that in this era, due to the small-scale peasant economy and society, the people lacked living resources, had a closed mind, lacked manpower and material resources, and had no experience in large-scale breeding. They generally only used family-style free-range breeding. In times of disaster,  It¡¯s difficult. The refugees themselves can¡¯t feed themselves, so naturally they can¡¯t support these things.

    Compared with the ancient breeding industry, modern intensive breeding has absolute advantages in many aspects, but it will cause too much pollution and damage to the environment, and even with the conditions under Li Zhe, it is impossible  Reach a high degree of concentration.  Everything must be based on current conditions.

    In short, under the current social conditions of the Three Kingdoms, a certain degree of intensification can be carried out, but in terms of specific breeding methods, it is better to use the traditional free-range breeding method and pay attention to the circular economy model.

    To intensively breed, there must be a large amount of grain surplus. Otherwise, it will be difficult to raise high-quality livestock and poultry just by driving cattle and sheep to graze.

    This is linked to the development of agriculture.

    In fact, the cultivation of many grains can be recycled together with the breeding industry. For example, sweet potato vines are an excellent breeding feed. They are nutritious and delicious food for all kinds of large livestock.  The manure produced by large livestock and poultry every day is also a good fertilizer, which is of great help in increasing grain production.

    Agriculture in this era has not yet formed a tradition of fertilization, and there is little understanding of the role of biofertilizers. The ability to plow the ground deeply is already the most advanced technology.

    So there is still a lot to be done in this regard.

    "The high yields of these high-yield crops that Li Zhe is currently promoting in the Three Kingdoms time and space do not fall from the sky. To maintain such high yields, they consume unprecedented amounts of land fertility.  Although the land in the Three Kingdoms time and space is much more fertile than in modern time and space, the nutrients in the land will be exhausted after several consecutive generations of planting. In ancient times, the land was usually left fallow.

    We need to take a long-term view and solve this problem in advance. The way is to use chemical fertilizers like modern times and use chemical fertilizers to replenish land fertility.  Otherwise, if the land is used in this way, the high yield of food will inevitably decline in a few years. Although the yield is still much higher than that of ordinary crops, it will not be as grand as it used to be.

    Therefore, during the Three Kingdoms period, playing with soil and chemical fertilizers, making homemade fertilizers, and strengthening land fertility were still very promising.

    50 kilograms of fresh cow dung, 50 grams of soybean flour, and 5 kilograms of plaster of paris powder are sealed and placed below 25 degrees for 3 days. When applied with 3 times of water, the fertilizer efficiency is even higher than that of ammonia water.  Mix 50 kilograms of ammonium sulfate human urine, 5 kilograms of plaster of paris, and 25 kilograms of water. Mix well and apply after 10 days of sealing. The fertilizer effect is equivalent to ammonium sulfate.

    Nitrogen, ammonium and phosphorus complexAnimal bones are processed into bone meal, which is an important slow-acting agricultural fertilizer. It is generally used as a base fertilizer and can be divided into raw bone meal and cooked bone meal.  Raw bone meal is a powder obtained by simply cooking bones, removing part of the fat and then crushing them.

    It contains 2.6% nitrogen and 15.28% phosphorus pentoxide.  It is a high-nitrogen-phosphorus compound fertilizer. Cooked bone meal (also known as defatted bone meal) is made from bones after fat is extracted with a solvent, then steamed at high temperature and then crushed. It contains 1.5% nitrogen and 16.25% phosphorus pentoxide.  Its fertilizer efficiency is also high.

    These are the original homemade fertilizers that were vigorously promoted in the rural areas of modern China in the 1950s and 1960s. At that time, the chemical industry was not as developed as it was later. Only these methods could be used to replace chemical fertilizers, and the results were good.  The grain output per mu can be 20 to 30% higher than in the 1940s. This is generally implemented in the context of agricultural communes.

    ??But Li Zhe currently governs a civil society organization with Tianshi Dao believers and militia as the backbone. The actual situation of his society is fundamentally not far from that of an agricultural commune.  Of course, its level of organization is still far behind.

    Of course, Li Zhe couldn't come up with such a complicated ratio, and it was actually impossible to hand over the details to the farmers one by one on how to do it. He could only use the simplest method - directly mix livestock manure, soybean meal and lime.  The powder is mixed together in proportion to act as ammonia; various animal and human urine and lime powder are mixed together and stirred together to act as ammonium sulfate; for other base fertilizers, animal bones are simply steamed and ground into powder, and then used  Mix it into the farmland during deep plowing.

    In this way, everything must be simplified to be implemented. As for the effect, it must be much better than nothing.

    In addition, there are native pesticides that were widely used in China in the 1950s and 1960s in modern time and space.  Li Zhe also selected some that were easy to implement and made some.

    Grind the dried castor leaves into fine powder, mix it with soil fertilizer in a certain proportion and spread it on the ground to prevent and control underground pests such as grubs, mole crickets and cutworms.

    After soaking the castor leaf powder in water in proportion and pouring it into the farmland, it can also prevent ground maggots, cabbage caterpillars, leaf-eating beetles, etc. in the vegetable fields.  Dried castor leaf powder can also be made into leach liquid and sprinkled into toilets, livestock pens, manure pits, etc. It has obvious effects on dead mosquito larvae and fly maggots.

    In addition, there are also peach leaf liquid, mulberry leaf mixture, masson pine liquid, ailanthus leaf, rattan liquid, verbena liquid, purslane mixture, mugwort fresh grass liquid, calamus liquid, cha Ku liquid, neem leaf mixture, vegetables  Liquid, Ersijing, Fengyang liquid, etc. are all well-known home-made pesticides, which can effectively reduce various agricultural pests and diseases and are of great help to agricultural production.

    Li Zhe produced such a large amount of agricultural planting materials, so he called Su San and others to explain these things one by one. Although based on the current level of organization, the efficiency of its promotion must be extremely slow.  However, once this ground-breaking technological reform in agricultural technology appears, its vitality will become stronger and stronger in the long-term social evolution, showing long-term and far-reaching effects.
