Problems solved by technology

However, after the fertilizer is applied, the active ingredients are released quickly, resulting in the volatilization of nutrients or unbalanced supply of nutrients, which do not meet the needs of crop growth, and the utilization rate of fertilizers is low, which eventually causes problems such as waste of resources or soil

Abstract

The invention discloses a method for preparing a slow-release biological fertilizer and relates to the technical field of preparation of biological fertilizers with special functions. The method comprises the following steps: mixing dead animal bodies, soybean cakes and animal excrement, and composting so as to obtain a mixture A; crushing oil-tea camellia bran, pine needles, persimmon tree leaves, clove tree leaves, orange peel and tobacco leaves, and composting so as to obtain a mixture B; uniformly mixing the mixture A with the mixture B, and pelletizing. According to the slow-release biological fertilizer prepared by using the method disclosed by the invention, organic matters are not completely decomposed after incomplete composting and fermentation, a fermentation process can be slowly started after the fertilizer is applied into soil, and no chemical substance which cannot be recycled or degraded is used in the fertilizer, so that soil pollution can be avoided, the process is simple, and the cost is low; meanwhile, the fertilizer contains multiple trace gentle biological sterilization substances and insect killing and expelling substances, so that both the requirements of crop growth on nutrition are met and a part of harmful bacteria in the organic matter decomposition process can be killed, and insect eggs or harmful insects can be killed and expelled.

Description

technical field [0001] The invention relates to the technical field of preparation of biological fertilizers with special effects, in particular to a preparation method of slow-release biological fertilizers. Background technique [0002] Fertilizer occupies a very important position in agricultural production, and it is a material with a large investment in agricultural production. However, after the application of fertilizers, the active ingredients are released quickly, resulting in the volatilization of nutrients or unbalanced supply of nutrients, which do not meet the needs of crop growth, and the utilization rate of fertilizers is low, which eventually leads to problems such as waste of resources or soil compaction. In response to the above problems, some researchers have disclosed some methods for preparing fertilizers with slow-release / controlled-release functions. However, these methods generally have problems such as complex processes, high costs, and the need to u...
