1. Add bagasse to the garden soil according to the ratio of 1: 1, then add about 5% soybean meal or broken soybean cake, mix well and spray water for wetting.
2. Then add water, and the amount of water should be tight with hands and the hands should not touch the soil to form balls. Bagasse and soybean meal will ferment when they turn gray-black.
Extended data:
1. Fertilizer refers to a kind of substance that provides one or more essential nutrients for plants, improves soil properties and improves soil fertility level, and is one of the material bases of agricultural production. It mainly includes ammonium phosphate fertilizer, macro-element water-soluble fertilizer, medium-element fertilizer, biological fertilizer, organic fertilizer, multi-dimensional field energy concentrated organic fertilizer and so on.
2. Because a fertilizer often has many properties, besides the above classification, there are other common classification methods: ① According to the physical state of fertilizer, it can be divided into solid fertilizer and liquid fertilizer. Solid fertilizers are divided into powder fertilizers and granular fertilizers. Liquid fertilizer is a liquid fertilizer at normal temperature and pressure. ② According to the chemical properties of fertilizers, they can be divided into chemically acidic, chemically alkaline and chemically neutral fertilizers. (3) Fertilizers can be divided into physiologically neutral, physiologically alkaline and physiologically acidic fertilizers according to their effects on soil response after being selectively absorbed by plants. ④ According to the availability of nutrients to plants, fertilizers can be divided into quick-acting, late-acting and long-acting fertilizers.
3. In order to meet the needs of agricultural modernization, fertilizer production is developing in the direction of high-efficiency compounding, mechanization of fertilization, pipeline transportation of fertilizer and instrumentation of water and fertilizer sprinkler irrigation. Liquid ammonia, ammonium polyphosphate, potassium polyphosphate and so on. Because of its high nutrient concentration or few side components, it has become a major chemical fertilizer variety with great development. Many fertilizers tend to be made into liquid fertilizers, and trace element fertilizers and pesticides are mixed into them to become multifunctional compound fertilizers, which is convenient for the combination of pipeline transportation and fertilization irrigation (sprinkler irrigation and drip irrigation) and has the advantages of saving labor, water and fertilizer. With the development of protected agriculture (such as plastic greenhouse), the demand for carbon dioxide fertilizer for vegetables and melons will gradually increase. However, long-term application of chemical fertilizers often causes environmental pollution. In order to maintain the agricultural ecological balance, we should advocate the combined use of organic fertilizer and chemical fertilizer to meet the demand of crops for nutrients and avoid the deterioration of soil properties and environmental pollution.
