Compound microbial agent for promoting root growth, increasing yield and improving quality, and preparation method

Abstract

The invention discloses a compound microbial agent for promoting root growth, increasing yield and improving quality, and a preparation method. Bacillus subtilis, Trichoderma harzianum, Bacillus amyloliquefaciens, Bacillus laterosporus, Bacillus jelliformis, Bacillus licheniformis, Paecilomyces lilacinus, Paecilomyces lilacinus, auxiliary beauty powder and sugar carrier are mixed together to forma compound microbial agent for promoting root growth, increasing yield and improving quality, and its preparation method is scientific and reasonable. The production process is simple and the production cost is low, which improves the market competitiveness of the products. The invention has the advantages of nitrogen fixation, phosphorus dissolution and potassium decomposition, and can decomposefarmyard manure, and can improve the utilization rate of fertilizer; At the same time, it can effectively inhibit and kill pathogen, prevent insect pests and disease, enhance crop disease resistance and immunity, and overcome the obstacle of continuous cropping. It has the functions of loosening and improving soil, degrading pesticide residues, increasing agricultural planting benefit and improving ecological environment. Moreover, it is suitable for soil and agricultural development status quo with diversified application methods.

Description

technical field [0001] The invention relates to the field of microorganisms, in particular to a compound microbial bacterial agent for promoting roots and raising roots, increasing production and improving quality, and a preparation method thereof. Background technique [0002] At present, the biological fungus products that are promoted and sold in the market include biological fertilizers and biological agents. Biological fertilizers are basically made of soybean meal, manure, straw and fermented materials with a small amount of bacteria (effective active bacteria ≤ 0.5 billion / g). At present, the main disadvantages of bacterial fertilizer are: the source of raw materials is not strictly controlled, the fermentation is not thorough, the production process is unstable, the product quality is uneven, various pathogenic bacteria are carried, heavy metal residues exceed the standard, and the product effect is not ideal. [0003] Biological agents are divided into two forms: wa...

Problems solved by technology

[0002] At present, the biological fungus products that are promoted and sold in the market include biological fertilizers and biological agents. Biological fertilizers are basically made of soybean meal, manure, straw and fermented materials with a small amount of bacteria (effective active bacteria ≤ 0.5 billion / g). At present, the main disadvantages of bacterial fertilizer are: the source of raw materials is not strictly controlled, the fermentation is not thorough, the production process is unstable, the product quality is uneven, various pathogenic bacteria are carried, heavy metal residues exceed the standard, and the product effect is not ideal

[0003] Biological agents are divided into two forms: water and powder. According to long-term market research and market feedback, water-based biological agents are basically based on a single Bacillus subtilis or EM bacterial liquid in the market. At present, water-based biological agents are mainly The disadvantages are: the production process is too simple, the purity and activity of the bacteria are unstable, and in the process of production, transportation and storage, due to the drastic changes in the suitable conditions such as air, culture medium, PH value, temperature, etc., the effective and active bacteria in the liquid are geometrically multiplied. Attenuation and disappearance, the effect is quite different; under normal conditions, it only has a survival period of about 8 months, and it needs to be saccharified and rejuvenated before application. The operation process is cumbersome, increasing labor, time-consuming and labor-intensive, and the effective active bacteria and purity are not guaranteed. can not achieve the desired effect

[0004] Most of the powder biological agents are based on a single Bacillus subtilis (Bacillus subtilis ≥ 200 million / g) or a small amount of other strains are added, and some even replace Bacillus subtilis with amyloliquefaciens. The disadvantages are: the simple mixing of purchased solid commercial bacterial materials, the instability of the purity and activity of the strains, the wanton expansion of the content and application range of the strains, and even the auxiliary addition of regulator components or agricultural antibiotics, which makes some active bacteria antagonistic and spore inactivation , the purity, activity and water solubility of the bacteria cannot be guaranteed, and suspension or sedimentation often occurs, which is easy to block nozzles and drip irrigation equipment, and the effect is quite different. Bacteria, decompose soil organic matter, fix nitrogen, phosphorus and potassium, release medium and trace elements and beneficial elements, improve fertilizer utilization rate, increase production and improve quality. Those skilled in the art provide a compound microbial bacterial agent that promotes root growth, increases production and improves quality and preparation method thereof, to solve the problems raised in the above-mentioned background technology
