Problems solved by technology

In addition, the phosphorus fertilizers used in agricultural production for a long time are mainly chemical phosphorus fertilizers, and water-soluble phosphorus is prone to chemical fixation or adsorption fixation after entering the soil, resulting in a large amount of phosphorus accumulation in the soil that is difficult for plants to absorb and utilize, greatly reducing the utilization rate of phosphorus fertilizers. It also causes phosphorus pollution

Embodiment 1

[0026] 1. Isolation of Bacillus fusiformis LW-3

[0027] The soil collected from the ancient well in Jiangmen, Guangdong will be air-dried and ground into powder to obtain a soil sample; 5g of the sample will be weighed, dissolved in a triangular flask containing 45ml of sterile water and glass beads, and shaken by a 150rp oscillator; after shaking, it will be 10-1 times Place the conical flask in a water bath at 80°C for 30 minutes, then use a pipette to pipette 1ml into a 9ml sterile water test tube, fully shake it into a 10-2 times dilution, and dilute it into 10-5 times dilution;

[0028] Prepare a phosphorus-dissolving potassium-dissolving medium, sterilize at 121 °C for 30 minutes, take 0.1 ml of the dilution, spread it on the medium, and then place it in an incubator for cultivation. Take and streak on the nutrient agar (NA) medium, then pick a single colony, do a phosphorus-dissolving and potassium-dissolving effect test, and select the bacterial strain with the best ...

Abstract

The invention provides lysinibacillus fusiformis and application thereof, and belongs to the technical field of agricultural microorganisms. The classified name of the lysinibacillus fusiformis is lysinibacillus fusiformis LW-3, and the preservation number is CGMCC No.16228. The lysinibacillus fusiformis LW-3 with the preservation number being CGMCC No.16228 has the functions of phosphate solubilization and potassium dissolving, soil is regulated, soil fertility can be effectively improved, the usage amount of chemical fertilizer is decreased, the soil environment is improved, and good growthof plants is promoted.

Description

technical field [0001] The invention relates to a bacillus, in particular to a spindle-shaped lysine bacillus and an application thereof, belonging to the technical field of agricultural microorganisms. Background technique [0002] Phosphorus is an important nutrient in plant growth. Phosphorus is a component of nucleic acids and nucleotides, and is an important element that composes the nucleus and various organelles. Phosphorus deficiency will affect the division and formation of plant cells, resulting in poor root development, slow plant growth or even stagnation. In addition, phosphorus is a component of phospholipids, adenosine triphosphates and many enzymes, and is an important participating substance in various processes of plant photosynthesis. When phosphorus is deficient, leaves are dark green and dull, plants are dwarfed, and resistance is weakened, which directly affects crop yield and quality. [0003] Potassium also plays an important role in plant growth an...
