What are the precautions for the application of fermented organic fertilizer?
Organic fertilizer can significantly improve the soil, improve the quality of products, and reduce the advantages of crop diseases and insect pests. Unlike chemical fertilizers, it is not easy to kill dead plants. Studies have shown that the application of organic fertilizer has a significant increase in production and stable production. Without fertilization, all soil nutrients (C, N, P) were reduced except for total soil potassium; application of organic fertilizer significantly increased available P, K nutrient content, and organic carbon and total phosphorus. Organic fertilizer has the following advantages:
1. Improve soil and fertility. After the organic fertilizer is applied to the soil, the organic matter can effectively improve the soil physical and chemical status and biological characteristics, ripen the soil, and enhance the soil's ability to retain fertilizers, fertilizers, and buffers, and to create good soil conditions for the growth of the crop.
2. Increase production and improve quality. Organic fertilizers are rich in organic matter and various nutrients to provide nutrition for crops. After organic fertilizers are decomposed, they provide energy and nutrients for soil microbial fermentation activities, promote microbial activities, accelerate the decomposition of organic matter, and produce active substances that can promote the growth of crops and improve the quality of agricultural products.
3. Improve the utilization of fertilizers. Organic fertilizers contain many nutrients but relatively low levels and release slowly. Fertilizers, on the other hand, have high levels of nutrients, fewer ingredients, and faster release. The two are applied rationally and complement each other, and organic acids produced by the decomposition of organic matter can also promote the dissolution of mineral nutrients in soil and chemical fertilizers. Organic fertilizer and chemical fertilizer promote each other, which is conducive to crop absorption and increase fertilizer utilization.
However, excessive application of organic fertilizer will also have the same hazard as excessive application of chemical fertilizers. It is characterized by the difficulty of water absorption in the roots of crops, prone to yellowing of burned roots, lack of stiff seedlings, and deformed leaves. The serious consequence is that crops gradually shrink and die. Correct application of organic fertilizer Note the following:
First, fully cooked fermentation before use. In the natural world, organic fertilizers, such as poultry pens, human and animal manures, and cakes, must be fully decomposed and fermented before being applied. After fermentation, first, it balances the acidity of the organic fertilizer, reduces the nitrate content, supplements the moisture, and is beneficial to the combined application of the microbial bacteria in the natural soil; second, it can kill the parasite eggs in the original manure after fermentation, and is harmful. Biological bacteria and other pathogens and hazards directly to crops and soil. The use of a type of fertilizer Fermentation Fermenter decoction fermentation can be fully decomposed in a short time, decomposed organic fertilizer nutrient conversion rate is high, completely decomposed, will not cause secondary decomposing burning root burning seedlings. After diluting organic fertilizer starter, Jinbao directly ferments with organic materials. Generally, it completes basic decomposing after three times of falling in 7-10 days.
Second, according to the soil conditions, the appropriate amount of fertilizer and other fertilizers. Organic Fertilizer and Chemical Fertilizer Coupling Application Different crops vary to grasp the amount of fertilizer Fertilizer Organic fertilizer and chemical fertilizer have their own strengths and weaknesses. Taking into account the rationality and possibility, the amount of fertilizer to be used varies from crop to crop. Promote the application of organic fertilizer on field crops, generally 1,000 to 3,000 kilograms of organic fertilizer applied to the Mushi; organic fertilizers must be applied to fruit trees and vegetables, of which fruit trees and open-field vegetables are generally 3,000 to 4,000 kilograms, greenhouses and other protective vegetables are generally 4000 to 7,000. kg. In combination with mineral fertilizers and chemical fertilizers, the balanced fertilization technology guides fertilization according to the nutrient requirements during the growing season, generally 1-2% of biofertilizer, 50-60% of organic fertilizer, 10-20% of trace element fertilizer, and a large number of nitrogen, phosphorus and potassium elements. Fertilizers have the best mix of 30-40%.
Third, try to make the base fertilizer after deep plowing. One way to improve fertilization is to try to deepen or cover the organic fertilizer into the soil to avoid spreading fertilizer on the surface and reduce the loss of fertilizer and environmental pollution. Second, the basic fertilizer should be applied deep or early in the crop seedling period, especially strict Control the application of nitrogen fertilizer at seedling stage; the third is to apply fertilizer according to the law of nutrient demand for crop growth. Generally, short-term growth crops can be used as base fertilizer for one-time application. For example, long-term growth cotton cultivation and fertilization should be applied before and after application. , that is, "before the light, heavy" to be properly applied to achieve the desired target output effect.
Fourth, with the use of microbial microbial fertilizer fertilizer application. In real production, the lack of organic matter in the soil makes it easy for crops to produce diseases and produce low yields. Applying more organic fertilizer can not only increase the yield and quality of crops, but also make the crops drought-resistant, anti-premature and disease-resistant. The application of the fermented organic fertilizer together with the golden baby microbial fertilizer can enable the soil to have a better function of nitrogen fixation, phosphate release, and potassium release, thereby improving the soil, increasing the utilization rate of the fertilizer, saving the cost, increasing the production, and increasing the income.
