Abstract

The invention relates to a composite microbiological bacteriocin saline-alkali soil improver, and a preparation method and applications thereof. The composite microbiological bacteriocin saline-alkali soil improver comprises a microbial agent, an organic liquid and a matrix. The microbial agent specifically comprises bacillus subtilis and bacillus megaterium, and nutrient substances of protease, lipase, alfa-amylase, amino acid and the like can be genereated by fermentation of the microbial bacteriocins; and the microbial agent can be used to adjust soil acidity-alkalinity, reduce saline-alkali toxicity, adjust rice root system microbial environment, accelerate transition of trace elements comprising nitrogen, phosphorus and potassium, and accelerate root growth, root increase, seedling development and seedling strengthening, and helps to lay a good foundation for increase of rice production.

Description

technical field

[0001] The invention relates to the field of biological bacterial fertilizer technology and saline-alkali land treatment, in particular to a compound microbial bacterial element saline-alkali land improver and its preparation method and application. Background technique

[0002] The ecological restoration and improvement of saline-alkali land is a project that benefits the country and the people. It can increase the area of ​​cultivated land, tap agricultural potential, ensure food production, and is more conducive to the development of the agricultural industry. It is conducive to expanding the grain planting area and ensuring the effective supply of grain. In Inner Mongolia, Jilin and other regions of China, good results have been achieved in saline-alkali land management. There are also many patents in saline-alkali land management. For example: Chinese patent CN101481281A (application date: 2009 February 3, application number: 200910066498.0, applicant: J...
