Special microbial agent for natural alpine grassland as well as preparation method and application of special microbial agent

Abstract

The invention provides a special microbial agent for natural alpine grassland as well as a preparation method and an application of the special microbial agent, and belongs to the field of agricultural microbial agents. The microbial agent is mainly prepared from the following raw material components: growth-promoting bacterium fermentation liquor, livestock manure decomposing bacterium fermentation liquor, pasture litter decomposing bacterium fermentation liquor, rhizobium fermentation liquor and auxiliaries. The microbial agent disclosed by the invention has the effects of increasing the content of nitrogen and available phosphorus in soil, resisting pathogenic fungi and reducing the incidence rate of diseases, so that the growth of pasture can be promoted, and the yield of the pasture can be increased; the effects of promoting decomposition of grassland litters and livestock manure, promoting nutrient circulation and improving grassland nutrients are achieved; the active strain is separated from the high-cold environment, and has good endurance capacity to the low-temperature and strong-ultraviolet environment of the high-cold grassland, so that the active strain is more easily colonized and survived at the rhizosphere of pasture in the high-cold grassland, and the effect is stable and reliable; the active strain is separated from intergrassroots of indigenous grasslands in alpine grasslands, so that the environmental biological safety risk is avoided.

Description

technical field [0001] The invention belongs to the field of agricultural microbial inoculum, in particular to a special microbial inoculum for natural alpine grassland and its preparation method and application. Background technique [0002] The alpine grassland is an important type of grassland, and it is also one of the most important types of grassland in the Qinghai-Tibet Plateau region. The alpine grassland region of the Qinghai-Tibet Plateau is the birthplace of many important rivers including the Yangtze River, the Yellow River, and the Lancang River. It is the source of my country's water resources. and key areas of ecological security. Extreme environmental conditions make the alpine grassland distribution area a vulnerable area of ​​my country's terrestrial ecosystem. In recent decades, under the double influence of climate change and human activities, the alpine grassland vegetation has undergone a series of obvious changes, the grassland productivity has serious...

AI Technical Summary

Problems solved by technology

[0007] To sum up, the special microbial agent for alpine grassland is a kind of new agricultural science and technology product of great value to the national economy, but there is still a lack of such products in our country, which is not conducive to grassland management and degraded grassland restoration
