Why does the endophytic flora of microorganisms increase in the later stage of plant growth?

1. Bacillus subtilis: increase crop stress resistance and nitrogen fixation.

Second, Bacillus megaterium: a phosphate-solubilizing bacterium, which can degrade organophosphorus in soil very well.

3. Bacillus mucilaginosus: Dissolve potassium and release soluble phosphorus, potassium and trace elements such as calcium, sulfur, magnesium, iron, zinc, molybdenum and manganese.

4. Bacillus licheniformis: resistant to diseases and killing harmful bacteria,

5. Bacillus thuringiensis: insecticidal (including root-knot nematodes), with specific toxic activity to arthropods such as Lepidoptera.

6. Bacillus laterosporus: promoting roots, sterilizing and degrading heavy metals,

7. Bacillus mucilaginosus: It has phosphorus, potassium and nitrogen fixation functions, secretes a variety of enzymes, and enhances the resistance of crops to certain diseases.

Streptomyces Jingyang: It has the ability to enhance soil fertility and stimulate crop growth.

Nine, mycorrhizal fungi: expand the absorption surface of the root system and increase the absorption capacity of elements (especially phosphorus) outside the absorption range of the original root hair.

X. brown nitrogen-fixing bacteria: fixing the free nitrogen in the air and increasing the yield.

1 1. Photosynthetic flora: it is the main force to enrich the soil and promote the growth of animals and plants.

12. Bacillus coagulans: It can reduce harmful gases such as ammonia and hydrogen sulfide in the environment. Improve the content of amino acids in fruits.

Thirteen, Aspergillus oryzae: make the organic matter in straw become the nutrition needed for plant growth, improve soil organic matter and improve soil structure.

Paecilomyces lilacinus: It can control many kinds of nematodes and is the most promising biological control agent for root-knot nematodes.

More than three kinds of compound bacteria promote each other and complement each other, and the effect of resisting soil-borne diseases is far greater than that of single bacteria. Beneficial bacteria cooperate with each other and work together to achieve high yield of crops.

1, promoting rapid growth: beneficial microorganisms such as Bacillus megaterium and Bacillus mucilaginosus in the flora produce a large number of plant endogenous enzymes during metabolism, which can obviously improve the absorption rate of nutrients such as nitrogen, phosphorus and potassium for crops.

2. Adjust life activities, increase production and income: beneficial bacteria such as Bacillus mucilaginosus, Bacillus laterosporus and Bacillus licheniformis in the flora can promote the growth of crop roots and increase fibrous roots. Endogenous enzymes and plant growth regulators produced by metabolism of beneficial microbial flora enter plants through roots, promote photosynthesis of leaves and regulate the flow of nutrients to fruits, which has obvious effects on expanding fruits and increasing production. Compared with the application of chemical fertilizer, the yield can be increased by 15%-30% with the same input.

3. The fruit quality is obviously improved: Bacillus laterosporus, Bacillus subtilis and Bacillus coagulans in the flora can reduce the nitrate content in plants by more than 20%, reduce the heavy metal content, increase the Vc content in fruits by more than 30% and increase the soluble sugar by 2-4 degrees. Lactic acid bacteria, Lactobacillus acidophilus, Bacillus coagulans and Bacillus subtilis can increase the contents of essential amino acids (lysine and methionine), vitamin B group and unsaturated acids in fruits. The fruit has good taste, storage resistance and high price.

4. Decomposition of organic matter and toxin to prevent continuous cropping: beneficial microorganisms such as Aspergillus oryzae, Bacillus licheniformis and Bacillus subtilis in the flora can accelerate the decomposition of organic matter, provide quick-acting nutrients and power for crops, decompose toxic and harmful substances in continuous cropping and prevent continuous cropping.

5. Protection barrier of rhizosphere environment: After beneficial microorganisms such as Bacillus licheniformis are applied to the soil, they quickly propagate into dominant flora, control rhizosphere nutrition and resources, and make pathogens such as continuous cropping, root rot, damping-off, gummosis and gray mold lose their living space and conditions. The cell wall of plant root cells is thickened, fiberized and lignified, forming a horny double silicon layer, forming a solid barrier to prevent the invasion of pathogenic bacteria.

6. Enhance stress resistance: beneficial microorganisms such as Bacillus licheniformis, Bacillus megaterium and Bacillus laterosporus in the flora can enhance soil buffering capacity, retain water and moisture, and enhance crop drought, cold and waterlogging resistance; At the same time, Bacillus laterosporus can strengthen the protective film of leaves, resist the infection of pathogenic bacteria and resist pests and diseases.
