Abstract

The invention relates to the technical field of biological agents, in particular to a biological agent for improving soil fertility and a preparation method thereof. The biological agent is prepared from the following components: a composite microbial agent, a mushroom dreg fermentation product, a fruit waste fermentation product, bone dregs and fulvic acid, wherein the complex microbial agent comprises complex microorganisms and auxiliary materials, and the complex microorganisms are composed of bacillus subtilis, bacillus mucilaginosus, bacillus natto, azotobacter chroococcum, clostridium thermocellum, saccharomyces cerevisiae and lactobacillus plantarum. The compound microorganisms in the biological agent are high in survivability in soil and can stably propagate so that the organic matter conversion capacity of the soil is improved, and the soil can keep good fertility for a long time. Meanwhile, the biological agent contains rich organic components, and can quickly supplement soilfertility. Moreover, the biological agent can improve the soil fertility, improve the soil hardening and hardening conditions and increase the air permeability and porosity of the soil at the same time.

Description

technical field [0001] The invention relates to the technical field of biological preparations, in particular to a biological preparation for improving soil fertility and a preparation method thereof. Background technique [0002] With the application of more and more inorganic fertilizers, the beneficial microorganisms in the soil are constantly being killed, and the activity of enzymes in the soil is inhibited, which affects the activities of soil microorganisms and the transformation of organic matter. On the one hand, excessive salt ions can inhibit the reproductive growth and vegetative growth of plants, and some ions can also directly poison plants, causing changes in the shape and structure of plants. On the other hand, the utilization rate of soil nutrients decreases, and organic matter content decreased, leading to a decrease in soil fertility. After excessive fertilization of the soil, the porosity and oxygen absorption capacity of the soil will become worse and w...
