Abstract

The invention aims to solve the problems existing in an existing alkaline soil improvement technique, and provides a saline-alkali soil improvement agent containing composite microbial agents and a preparation method and application of the saline-alkali soil improvement agent containing composite microbial agents. The saline-alkali soil improvement agent disclosed by the invention consists of glomus mosseae, azospirllum brasilense and solid carriers, wherein the mass ratio of total number of effective viable bacteria of the glomus mosseae and the azospirllum brasilense to the solid carriers is1*10<5>-9*10<7> / gram, the ratio of the number of the glomus mosseae to the number of the azospirllum brasilense is 1 to (0.2-5). The saline-alkali soil improvement agent has good effects on plage saline-alkali soil improvement. The application of the saline-alkali soil improvement agent is a method for microorganism ecological improvement of saline-alkali soil, which is simple to operate, low incost and pollution-free.

Description

technical field [0001] The invention belongs to the technical field of saline-alkali land improvement, and in particular relates to a seaside saline-alkali land improvement agent containing a microbial compound bacterial agent, a preparation method and an application. Background technique [0002] Saline-alkali land is widely distributed in my country, with about 9.9×10 7 hm 2 , of which coastal saline-alkali land accounts for nearly 40%. Although these saline-alkali lands can grow crops, the survival rate is not high. According to the research, when the soil is in the medium level of saline soil (salt content between 0.3% and 1.0%), the crop yield will be reduced by about 95%, and the planting situation in severely saline-alkali land is even more severe. [0003] In the existing invention patent technology, the improvement of coastal saline-alkali land generally adopts physical improvement, application of organic fertilizers, addition of chemical amendments and other met...
