Double-layer microcapsule biological soil conditioner and preparation method thereof

Abstract

The invention relates to a biological soil conditioner double-layer microcapsule and a preparation method thereof, the main components of the biological soil conditioner double-layer microcapsule are compound bacteria, organophosphorus degrading enzyme and a plant extract microcapsule, the three effective components are included in a sustained-release membrane, the plant extract microcapsule is wrapped in an outer-layer sustained-release membrane to form a double-layer microcapsule structure, the conditioner can be released durably so that the action time of the biological soil conditioner is prolonged, besides, ingredients in the plant extract can promote the growth of bacteria and generate biological enzymes beneficial to soil conditioning, the conditioner can take effect quickly, the long-term effective conditioning effect is maintained, frequent and repeated application is avoided, and the cost and workload of soil conditioning are reduced. The preparation method of the biological soil conditioner double-layer microcapsule is simple and convenient, the prepared microcapsule is good in slow release performance, the effective components can be released durably and slowly, the service time of the soil conditioner is prolonged, the use frequency is reduced, and the soil conditioning cost is reduced.

Description

technical field [0001] The invention relates to the technical field of soil conditioners, in particular to a double-layer microcapsule biological enzyme conditioner and a preparation method thereof. Background technique [0002] In recent years, due to the improper application methods, habits and dosage of chemical fertilizers, the physical and chemical properties of the soil have deteriorated, the fertility of the soil has decreased year by year, soil compaction and acidification have become more serious problems. my country is now facing severe soil environmental pollution problems. The excess of nitrogen, phosphorus, potassium and polycyclic aromatic hydrocarbons is one of the serious problems facing the soil. Aiming at the problems of high pesticide residues in the soil, soil compaction, and the existence of many toxic and harmful organic substances, there are many technologies in the prior art that use microorganisms to repair the soil. For example, the Chinese patent...

Problems solved by technology

Aiming at the problems of high pesticide residues in the soil, soil compaction, and the existence of many toxic and harmful organic substances, there are also many technologies in the prior art that use microorganisms to repair the soil. For example, the Chinese patent document with the publication number CN103305497B discloses a method for Microcapsules for immobilized enzyme repairing organic polluted soil and its preparation method, the Chinese patent document with the publication number CN111607404A discloses a preparation method of a compound bacterial soil conditioner and its products, and the Chinese patent document with the publication number CN106190883A discloses a A soil-improving composite bacteria composition and a preparation method thereof, these prior art plays the role of repairing the soil to a certain extent, but the biological soil conditioner of the prior art generally has a short effective time, needs to be supplemented repeatedly, consumes a lot but Conditioning repair is slow
