Abstract

The invention provides bacillus mucilaginosus with the CGMCC No. 16005. The invention also provides a microbial fertilizer which contains the bacillus mucilaginosus mentioned in the technical scheme,a carrier and an organic fertilizer, wherein the bacillus mucilaginosus mentioned in the technical scheme is compounded on the carrier. The bacillus mucilaginosus provided by the invention has relatively strong decomposition capacity for potassium-containing silicate ore such as mica and feldspar in soil, can be used for dissolving potassium and solubilizing phosphorus in agricultural production,and is very easy to form a root system dominant species. The microbial fertilizer for planting fruits, vegetables and crops can enhance the cold resistance, drought resistance, disease resistance andstress resistance of crops and flowers, and significantly reduces the phenomena of leaflets, yellow leaves and early leaf fall.

Description

technical field [0001] The invention belongs to the technical field of microbial fertilizers, and in particular relates to jelly-like bacillus, microbial fertilizers, a preparation method and applications thereof. Background technique [0002] Due to the excessive use of inorganic fertilizers, the soil quality of flowers in my country is generally poor at present, especially in the low carbon-nitrogen ratio of the soil, which leads to the destruction of the soil microbial system and the continuous reduction of beneficial microorganisms, which seriously affects the growth and development of the root system. [0003] Over the years, the application of chemical fertilizers has played a key role in increasing agricultural production and income. According to data, China's potash fertilizer production accounts for only 0.3% of the world's total, while its consumption reaches 14.7%. Although it imports more than 2 million tons of potash fertilizer every year, it still cannot meet t...
