Description

Technical Field

[0001] The invention belongs to the technical field of biofertilizers, and in particular relates to a method for preparing biofertilizers. Background Art

[0002] Fertilizer refers to a substance used to supply the nutrients needed by plants. It can promote plant growth and increase crop yields. It includes major elements such as nitrogen, phosphorus, and potassium, as well as trace elements such as iron and zinc. These nutrients play an important role in plant growth, such as promoting leaf growth, promoting flower and fruit development, and increasing plant disease resistance. Fertilizer can quickly replenish the nutrients needed by plants, increase the growth rate and yield of crops, and enable plants to obtain sufficient nutrients during the growing season, so as to better resist the effects of pests and diseases and adverse environments. In addition, fertilizer can also adjust the soil pH, improve soil structure, and increase soil fertility.

[0003] However, fertilizers also have some problems. First, excessive fertilization may cause the accumulation of nutrients, leading to soil and water pollution; second, excessive use of fertilizers can easily lead to soil nutrient imbalance and affect the health of the soil ecosystem; in addition, the traditional chemical fertilizer manufacturing and use process will have a negative impact on the environment.

[0004] In contrast, biofertilizer refers to fertilizer made from organic matter. It is made from natural organic matter, such as animal manure, plant residues, seaweed, etc., and is highly environmentally friendly. Secondly, biofertilizer contains rich organic matter and microbial communities, which can improve soil structure, increase soil water retention and aeration. In addition, the microorganisms in biofertilizer can also decompose organic matter, release organic nitrogen, phosphorus, potassium and other nutrients, and provide comprehensive nutritional support for plants. In contrast, biofertilizer is more environmentally friendly and sustainable, and has a more significant effect on improving soil quality. Since biofertilizer contains rich organic matter and microorganisms, it can improve soil fertility in the long term and reduce dependence on chemical fertilizers.

[0005] However, the nutrient content of biofertilizer is relatively low, the action speed is slow, and it takes a long time to release nutrients. Therefore, providing a method for preparing biofertilizer with high nutrient content is of great significance to agricultural development. Summary of the invention

[0006] The purpose of the embodiments of the present invention is to provide a method for preparing a biological fertilizer, aiming to solve the problems raised in the above background technology.
