Abstract

A soil microbial regulator for enhancing plant stress resistance, which includes the following components in parts by weight: 30-50 parts of coconut coir, 30-50 parts of Eucheuma, 10-30 parts of mushroom residue, 20-30 parts of Guayule and 0.4-1.6 parts of a composite bacterial agent. The present invention uses discarded mushroom residue and coconut coir as raw materials, and Guayule and Eucheuma are added; under the action of a composite bacterial agent, the raw materials are fermented; the soil microbial regulator prepared by fermentation can adjust the soil structure, improve soil microbial structure, provide sustainable nutrition for crop growth, significantly promote crop growth, improve crop resistance to diseases and insect injury, effectively reduce crop incidence rate, enhance crop resistance, realize the purpose of increasing yield and income, and achieve high and stable crop yield.

First claim

The invention claimed is:

1. A method for preparing a soil microbial regulator for enhancing plant stress resistance,
wherein the soil microbial regulator for enhancing plant stress resistance comprises in parts by weight: 30-50 parts of coconut coir, 30-50 parts of Eucheuma, 10-30 parts of mushroom residue, 20-30 parts of Guayule and 0.4-1.6 parts of a composite bacterial agent;
wherein, the composite bacterial agent comprises in parts by weight: 0.1-0.5 parts of Bacillus amyloliquefaciens, 0.1-0.5 parts of Bacillus laterosporus, 0.1-0.3 parts of Trichoderma asperellum, 0.05-0.15 parts of Paenibacillus polymyxa and 0.05-0.15 parts of Paecilomyces lilacinus ; and
the method comprises steps of: (1) crushing the coconut coir, the Eucheuma, the mushroom residue and the Guayule, and stirring evenly to obtain fermenting materials: (2) fermenting the composite bacterial agent comprising the Bacillus amyloliquefaciens , the Bacillus laterosporus , the Trichoderma asperellum , the Paenibacillus polymyxa and the Paecilomyces lilacinus , after adding respectively water and stirring evenly, adding composite bacterial agent to the fermenting materials, adjusting the water content of the materials by 30-50%, and fermenting for 5-7 days to obtain the soil microbial regulator.

2. The method for preparing the soil microbial regulator for enhancing plant stress resistance according to claim 1 , wherein the soil microbial regulator for enhancing plant stress resistance comprises in parts by weight: 40 parts of coconut coir, 45 parts of Eucheuma, 20 parts of mushroom residue, 25 parts of Guayule and 1 part of composite bacterial agent.

3. The method for preparing the soil microbial regulator for enhancing plant stress resistance according to claim 1 , wherein the composite bacterial agent comprises in parts by weight: 0.3 parts of Bacillus amyloliquefaciens, 0.3 parts of Bacillus laterosporus, 0.2 parts of Trichoderma asperellum, 0.1 part of Paenibacillus polymyxa and 0.1 part of Paecilomyces lilacinus.

4. The method for preparing the soil microbial regulator for enhancing plant stress resistance according to claim 1 , wherein a number of effective viable bacteria in the soil microbial regulator obtained by fermentation is not less than 2.0×10.sup.8 CFU.

5. The method for preparing the soil microbial regulator for enhancing plant stress resistance according to claim 1 , wherein, when the soil microbial regulator is used to improve plant stress resistance, a dosage of the soil microbial regulator is 30-50 kg per mu of land.
