How to apply organic fertilizer?

How to apply organic fertilizer? Please introduce the method of bio-organic compound fertilizer, which uses organic fertilizer combined with inorganic fertilizer and accompanied by a variety of microorganisms or high-energy compounds, which is very popular among farmers and has obvious effects: first, it can improve the physical and chemical properties of soil, enhance the performance of water and fertilizer conservation, and improve the ability of sustainable fertilizer supply; second, it can significantly inhibit cotton, melon Fusarium wilt, rice sheath blight and other diseases, and enhance stress resistance. Third, it can improve the quality of crops, especially to improve the sweetness of fruits such as watermelons, sugar cane and strawberries; fourth, it can promote the increase of crop production, and the general application of bio-organic compound fertilizer can increase the yield by about 10% compared with that of chemical fertilizer alone; fifth, it can reduce the pollution of the agricultural environment and produce a large number of pollution-free food. Although bio-organic compound fertilizer has many significant advantages, its market share is still limited, and the application of bio-organic compound fertilizer varies greatly from place to place. The main reasons are that some places reflect that the sales price is too high for farmers to bear; some reflect that the fertilizer effect starts slowly and the dominant effect of crops is weak; and some farmers who grow vegetables in plastic greenhouses report the phenomenon of burning seedlings. Why do these problems arise? First, the price of raw materials for the production of fertilizer is too high, there are too many intermediate links in sales, and the price is increased layer by layer; second, the single application of bio-organic compound fertilizer ignores the role of other fertilizers, or the application amount is too low; third, the soil moisture is insufficient when fertilizing, or the temperature is too low at that time; fourth, the application amount is too large at one time. In this regard, in order to give full play to the fertilizer effect of bio-organic compound fertilizer, the methods of increasing production and saving expenditure, correct guidance and scientific use should be adopted to accelerate the popularization and application. First of all, it is necessary to reduce production costs. First, the local use of organic raw materials, not long-distance transportation, increase costs; second, reduce sales intermediate links, production and sales close docking; third, do a good job in after-sales service, organize science and technology to the countryside, so that fertilizer efficiency can be brought into play quickly. Secondly, it should be applied with adequate moisture and suitable temperature. No matter what kind of soil is applied, there should be sufficient moisture to promote its rapid decomposition and transformation. The fertilizer effect is better when the temperature is in the range of 10 ℃-30 ℃. When the temperature is lower than 10 ℃ or higher than 35 ℃, fertilizer conversion and absorption will be hindered. Third, it should be used correctly. First, in order to make the fertilizer reflect the sustained effect of long-term and quick effect, in all fields where bio-organic compound fertilizer is applied, about 30 kg of ammonium bicarbonate per mu should be applied, and then other nutrient elements should be applied according to the needs of different crops. bio-organic compound fertilizer should not be used instead of other fertilizers. Second, as a base fertilizer, the amount of fertilizer per mu is not more than 50 kg. In particular, vegetables grown in plastic greenhouses should not be overused. Third, when soil moisture is insufficient, it is necessary to resist drought and adjust soil moisture in time after application.
