A kind of bacillus xiamen and application thereof

Abstract

The present invention provides a potassium-solubilizing bacteria, which is Bacillus xiameni XJC-HK-7, and the deposit number is CCTCC NO: M 2017619. The present invention selects Bacillus xiameni XJC-HK-7 capable of degrading insoluble aluminosilicate inorganic minerals from soil, and the potassium solubilizing bacteria can effectively decompose insoluble aluminosilicate inorganic minerals such as potassium feldspar, and promotes Insoluble potassium, phosphorus, silicon, magnesium and other nutrients are converted into soluble nutrients, increasing the content of available nutrients in the soil, promoting crop growth and development, and increasing yield. It is of great significance and application value to give full play to soil ecological fertility and maintain the balance of agricultural ecological environment.

Description

technical field [0001] The invention belongs to the field of microorganisms, and in particular relates to a bacillus xiameni and an application thereof. Background technique [0002] Potassium is one of the three elements of crop nutrition. It is ubiquitous in crops. Its function is related to plant metabolism. It widely affects the growth and metabolism of crops in the form of an enzyme activator, which can activate enzymes. It has been found that about The activation of more than 60 enzymes is related to potassium, which plays a very important role in physiological processes such as light energy utilization, sugar metabolism, protein synthesis, cell osmotic regulation and enhancement of plant resistance. [0003] About 60% of the cultivated land in my country is deficient in potassium, and the content of available potassium in the cultivated land is increasing by (2-3)×10 per year. -6 The rate of decline caused the imbalance of nitrogen, phosphorus and potassium in the so...

AI Technical Summary

Problems solved by technology

[0003] About 60% of the cultivated land in my country is deficient in potassium, and the content of available potassium in the cultivated land is increasing by (2-3)×10 per year. -6 The rate of decline of the soil causes the imbalance of nitrogen, phosphorus and potassium in the soil, which affects the development of agriculture.

Supplementing potassium with chemical potassium fertilizer is a quick-acting potassium supplement method commonly used in my country's agriculture, but it causes soil structure damage, organic matter content decline, serious pollution, high cost, and short supply.
