What should we pay attention to when applying organic fertilizer (farm manure)? Please give guidance to the farming network to sort out the matters needing attention in the process of using organic fertilizer (farm manure), which are listed below for netizens' reference. First, organic fertilizer (farm manure) should be applied proportionally: scientific and technological knowledge that organic fertilizer is beneficial to the growth of crops, reasonably combine biological bacterial fertilizer with farm organic fertilizer, mineral fertilizer and chemical fertilizer, and adhere to the balanced fertilization skills according to the "four-in-one" formula, and guide fertilization according to the nutritional requirements of crops during the growing period. Practice has proved that the proportion of biological bacterial fertilizer 1%, organic fertilizer 50%, medium and trace element fertilizer 10%, nitrogen, phosphorus and potassium element fertilizer 30% is the best, and the effect of increasing yield can obviously be increased by 2030%. Note that organic fertilizer (farm manure) can only be used after decay and fermentation: organic biological fertilizer can activate soil, improve soil, strengthen the disease resistance, insect resistance and disaster resistance of crops, and improve crop character and yield. However, in the natural world, organic fertilizers such as livestock pen, human and animal manure and cake must be fully ripened and fermented before application. After fermentation, one is to balance the acidity of organic fertilizer, reduce the content of nitrate and make up for water, which is beneficial to the combined use of microorganisms in natural soil; second, after fermentation, it can kill parasitic eggs and harmful bacteria in the original manure, which can directly bring bacteria and damage to crops and soil. Third, organic fertilizer (farm manure) should be applied as base fertilizer as far as possible after deep ploughing: to improve the fertilization method, one is to apply organic fertilizer deeply or cover the soil as far as possible to avoid fertilizer application on the surface and reduce fertilizer loss and waste and environmental pollution; second, the base fertilizer should be applied deeply or early at the seedling stage, especially the amount of nitrogen fertilizer used in the seedling stage. Third, it is necessary to apply fertilizer according to the law of crop growth and nutrition demand. usually, crops with short growth period can be applied as base fertilizer at one time, such as cotton cultivation with long growth period, which should be applied in the first and later stages, that is, "light in front and heavy after". The ability to achieve the expected target yield effect. Attention 4, with the application of bio-organic fertilizer: in the actual production, the lack of organic matter in the soil is easy to cause bacterial damage to crops and low yield. More application of organic matter fertilizer can not only improve crop yield and character, but also make crops have the ability of drought resistance, premature senility resistance and pest resistance. In particular, the combined application of organic fertilizer and biological bacterial fertilizer can make the soil have better functions of fixing nitrogen, dissolving phosphorus and potassium, improving soil, improving fertilizer use efficiency and saving cost, increasing production and increasing income.
