Why can farm manure not be used until it is ripe?

Why can farm manure not be used until it is ripe? Please give me an introduction and ripening methods. Many farmers have consulted why farm manure needs to be mature before it can be applied. Therefore, the farming network has sorted out the harm of non-rotten application of farm manure and the operation methods of ripening, which are listed in detail below for netizens' reference. Harm of immature application of farm manure: first, unripe farm manure often contains a large number of bacteria and insect eggs, which is easy to cause root diseases and insect pests of fruit trees, but also pollutes the environment; second, the nutrients of unripe farm manure are mostly organic, which is not easy to be absorbed by fruit trees, which will cause fertilizer loss. Third, because farm manure produces a lot of heat when it is decomposed and fermented by microorganisms in the soil, it is easy to burn the capillary roots of fruit trees. Fourth, because farm manure absorbs a large amount of nitrogen when it is decomposed and fermented by microorganisms in the soil, resulting in short-term nitrogen deficiency in fruit trees. Harm 5. Because farm manure needs a process after microbial decomposition and fermentation in the soil, the fertilizer efficiency lags behind, which is difficult to be consistent with the growth rhythm and fertilizer period of fruit trees, which can not achieve the purpose of fertilization, or even cause adverse effects. Therefore, farm manure must be ripened before it can be applied. There are four kinds of ripening operation methods of farm manure: first, the loose accumulation method is used to loosely accumulate the manure of fresh livestock in the compost site, and keep good ventilation in the process of accumulation. Under the condition of high temperature, livestock manure decomposes quickly, and mature organic fertilizer can be produced in a short period of time, but nitrogen and other nutrients are lost greatly. Method 2. The livestock manure and urine extracted from the circle by the method of close accumulation and maturity are piled up layer by layer in the compost site and pressed at the same time. If it is too dry, add an appropriate amount of water to keep it moist. The height of the fertilizer pile should be 1.5m to 2m. When the pile is finished, seal it with soil. The temperature is generally kept at 15 ℃ to 35 ℃. By using this method, the accumulation of humus is more and the loss of nitrogen is less. after about 3 to 4 months, the organic fertilizer can reach the state of semi-decay, and the organic fertilizer can be fully mature after more than 6 months. Method 3. The method of loose and close cross accumulation and alternating accumulation can not only shorten the ripening time of organic fertilizer, but also reduce the loss of nitrogen. The fresh organic fertilizer is loosely piled up outside the circle about one meter high and is not pressed to facilitate fermentation. Generally, the temperature in the compost pile can reach 60 ℃ to 70 ℃ after 2 to 3 days, and fresh organic manure can continue to be accumulated layer by layer until the height is 2 m to 2.5 m. Seal the fertilizer pile with soil, maintain the temperature, hinder the entry of air, and prevent the loss of fertilizer and evaporation of water. Generally 1 and a half months to 2 months can reach semi-rotten state, after 4 months can be completely mature. 4. The rapid ripening method of bacteria spreads out the prepared organic materials (mainly the mixture of animal excreta and plant straw and other wastes, with a moisture content of about 50% Murray and 60%), and then sprinkles with the ripening agent, according to the proportion of 10 kg ripening agent (or using a bag of compound microbial fertilizer in Mumei soil) corresponding to 4 square organic materials. Where there are conditions, it is best to simply turn over to ensure that the ripening agent can be evenly mixed with organic materials. After completing the above steps, the stacking height is about 0.5 Murray 1 meter, and after the stacking is completed, the thermometer is inserted at a slope of 45 degrees from the ground. Observe once every morning and evening, if the temperature exceeds 60 ℃ for 2 days, it needs to be overturned. When the organic material is odorless and the stacking temperature drops below 40 ℃, it can be stacked and set aside (usually about 30 days before and after). The principle of microflora decay: because the microflora can effectively decompose the harmful organic matter and various residues in the soil, eliminate the root metabolites and various residues that affect the growth of crops in the soil, thoroughly purify the soil, and eliminate the soil diseases and poisons that cause continuous cropping. Through high temperature fermentation, the bacteria kill most of the bacteria and eggs at high temperature, and the heat-resistant actinomycetes in the bacteria propagate rapidly, secrete a large amount of chitinase, and decompose the insects and egg shells composed of chitin to achieve the purpose of killing insects and eggs, including root-knot nematodes, and eradicate root-knot nematodes. Microflora can transform immature farm manure into highly humic organic matter, double soil fertility and form soil aggregate structure in a short time, so as to effectively improve soil water retention and fertilizer retention, and achieve the effect of fertilizer efficiency and obvious yield increase.
