Abstract

The invention provides a forest drought-resistant growth-promoting colloidal matrix and application thereof. The matrix is formed by well mixing a solid bacterial agent, turf, perlite and vermiculite,the solid bacterial agent is formed by uniformly inoculating drought-resistant microbial combined bacteria liquid into a colloidal fermentation material, and the drought-resistant microbial combinedbacteria liquid is formed by compounding bacillus subtilis GE3, bacillus cereus Z77 and lactobacillus casei 1.0580. Drought-resistant growth-promoting activity of bacillus subtilis GE3 can be given into full play, and coordinated symbiosis effect of bacillus subtilis GE3 among strains can be brought into play; a water-washing cow dung and cow dung biogas residue mixed fermentation product is addedinto the matrix, so that microbial colonization survival performance is further improved, reutilization of waste resources like cow dung is realized, and the matrix has great value in actual application.

Description

technical field

[0001] The invention belongs to the technical field of seedling-raising substrates and forestry microorganisms, and in particular relates to a colloidal substrate for forest tree drought resistance and growth promotion and its application. Background technique

[0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0003] Substrate is an important part of seedling cultivation. It is an artificial soil prepared from organic and inorganic materials and microbial preparations according to the needs of seedling growth. Most of the foreign seedling substrates adopt the formulations of the 1960s and 1970s, such as the composite substrates A and B of Cornell University in the United States. At pre...
