Microbial soil conditioner capable of controlling successive cropping obstacles of sorghum, and purpose and application method thereof

Abstract

The invention relates to a microbial soil conditioner capable of controlling successive cropping obstacles of sorghum, and a purpose and an application method thereof. The microbial soil conditioner can effectively overcome the problem of successive cropping obstacles of sorghum, is Bacillus amyloliquefaciens sp. Pb-4 fermentation broth and can be used for controlling and regulation of soil with successive cropping obstacles of sorghum. The application method is to apply a weak solution of the microbial soil conditioner to soil of sowing lines of sorghum or soil in root zone of sorghum. The method is simple, easily practicable, low in cost and saving in labor, can effectively overcome successive cropping obstacles of sorghum, exerts yield-increasing effect on sorghum, is of great significance to sorghum producing districts where crop rotation of sorghum is hard to carry out, and accords with demands of development of ecological agriculture and sustainable agriculture.

Description

technical field [0001] The invention belongs to the application technology of microorganisms in agriculture, and mainly relates to a soil conditioner containing fermentation liquid of bacillus amyloliquefaciens, its use and its application method. Background technique [0002] Sorghum is one of the five most important cereal crops in the world. It is not only edible, but also used as a raw material for industry, brewing, and feed. The use of sweet sorghum to produce biomass energy is also one of the important measures to deal with global climate change. At present, the sowing area of ​​sorghum in my country is 670,000 hectares, and the output is 2.7 million tons. It is mainly planted in Inner Mongolia, Jilin, Liaoning, Sichuan, Guizhou, and Shanxi. Most of them are in areas where the brewing industry is developed or the soil is relatively barren; Sorghum is grown organically, and sorghum continuous cropping obstacles have greatly affected the output of Moutai; in Shanxi, Guiz...

Problems solved by technology

[0003] Although there are some anti-cropping agents that control crop continuous cropping obstacles in China at present, as the Chinese patent authorization announcement number is: CN101735818.B "microbial soil conditioner prepared by edible mushroom chaff and preparation method thereof", which is to utilize Bacillus megaterium, colloid A conditioner prepared by mixing the Bacillus and Streptomyces hygroscopicus bacteria liquid with the conditioner carrier made from the fungus chaff; another example is the Chinese patent a
