A kind of preparation method of solid bacterial agent for pine

Abstract

The invention relates to the field of biological bacterial fertilizers, in particular to a method for preparing solid bacterial agents for pine trees. It includes the following preparation steps: 1) melting and mixing polylactic acid and fine powder fertilizer to obtain a polylactic acid / fertilizer composite material, followed by foaming to obtain a polylactic acid / fertilizer open-cell composite foaming material; 2) adding sodium methacrylate and branches on the surface of the foaming material; 3) Mixing and culturing the liquid of the sclerotidia and the foaming material to obtain the solid bacterial preparation of the sclerotidia. The present invention uses the polylactic acid / fertilizer open-pore composite foaming material as the carrier, and the pore wall in the foaming material is covered with fertilizer fine powder, and a large amount of yellow sclerotia is adsorbed on the surface of the pore wall, and the pores are released first when used. The fungus on the surface of the wall is yellow, and then the fine powder of the fertilizer is released with the degradation of the polylactic acid / fertilizer open-pore composite foam material, and the materials used are all biodegradable materials, which will not remain in the soil and are green and environmentally friendly.

Description

technical field [0001] The invention relates to the field of biological bacterial fertilizers, in particular to a method for preparing solid bacterial agents for pine trees. Background technique [0002] Mycorrhizae are a combination of mycorrhizal fungal hyphae and higher plant vegetative roots in natural soil, and are the most common symbiotic phenomenon of soil microorganisms and plant compatibility. The symbiotic fungi obtain the necessary carbohydrates and other nutrients from the plants, and the plants also obtain the required nutrients, water, etc. from the fungi, so as to achieve a highly unified combination of mutual benefit and mutual exchange. It has both The characteristics of general plant roots also have the characteristics of obligate fungi. Rhizomes are divided into endomycorrhizae, ectomycorrhizae and ectomycorrhizae. Ectomycorrhizae can greatly promote the growth of forest trees. Most of the ectomycorrhizae pass through the network system of epitaxial myce...

Problems solved by technology

[0004] In order to solve the problem of high fertilizer usage, high frequency of fertilization, serious waste of manpower and material resources in the prior art in the agricultural production process, it is impossible to meet the needs of different fertilizers for crops in different growth periods, and it is impossible to simultaneously load biological fertilizers and chemical fertilizers. And without the problem of mutual influence, it provides a solid microbial agent whose inner layer is placed in the pores of degradable foam material and whose outer layer is adsorbed with biological bacterial fertilizer.
