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 spindle-shaped lysinibacillus LW-3

[0027] Naturally air-dry the soil collected from the ancient well in Jiangmen, Guangdong, and grind it into powder to obtain a soil sample; weigh 5g of the sample, dissolve it in a triangular flask filled with 45ml of sterile water and glass beads, and vibrate with a 150rp oscillator; after shaking, it becomes 10-1 times Place the Erlenmeyer flask in a water bath at 80°C for 30 minutes, then use a pipette to pipette 1ml into a test tube filled with 9ml of sterile water, oscillate fully to obtain a 10-2-fold dilution, and then dilute to 10-5 times dilution;

[0028] Prepare a phosphorus-dissolving and potassium-dissolving medium, sterilize at 121°C for 30 minutes, take 0.1ml of the diluted solution, spread it on the medium, and then place it in an incubator for cultivation, observe the strains that produce phosphorus-dissolving circles and potassium-dissolving circles, and pick Get and streak on the nutrient agar (NA)...

Abstract

The invention provides a spindle-shaped lysine bacillus and an application thereof, which belong to the technical field of agricultural microorganisms. , and the deposit number is CGMCC No.16228. The spindle-shaped lysine bacillus LW-3 with the preservation number of CGMCC No. 16228 has the functions of dissolving phosphorus and potassium, can regulate soil, can effectively improve soil fertility, reduce the use of chemical fertilizers, improve the soil environment, and promote good plants. grow.

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 element in the process of plant growth. Phosphorus is a component of nucleic acid and nucleotides, and is an important element that forms the nucleus and various organelles. Phosphorus deficiency will affect the division and formation of plant cells, resulting in poor root development and slow or even stagnant plant growth. In addition, phosphorus is a component of phospholipids, adenophosphorus and many enzymes, and is an important participatory substance in various processes of plant photosynthesis. When phosphorus is deficient, the leaves are dark green and dull, the plants are short, and the resistance is weakened, which directly affects the yield and quality of crops. quality. [0003] Potassium also pla...
