The invention discloses an enzyme-bacterium duplex straw decomposing agent and its preparation and application methods. The decomposing agent is made by mixing a composite microbial agent and a composite enzyme agent in a weight ratio of 3-4:1. The composite microbial agent includes Trichoderma viride, Aspergillus niger, Aspergillus oryzae, Brevibacillus laterosporus and a fused Saccharomyces cerevisiae, having a weight ratio of (1-2):(1-2):(1-2):(2-3):(2-3). The composite enzyme agent includes cellulase produced by the fermentation of Trichoderma reesei, hemicellulase produced by the fermentation of Bacillus subtilis, and ligninase produced by the fermentation of Pleurotus ostreatus, having a weight ratio of (1-2):(1-2):(1-2). The decomposing agent has a double straw degrading function, allowing more efficient and more thorough biological degradation, increasing the straw degrading speed to a higher extent and shortening degrading time, and can fully decompose crop straw to fields within about a week, without affecting the planting and transplanting of next-stubble crops.

The invention belongs to the field of fertilizer, and particularly relates to a three-resistant compound microbial fertilizer and a preparation method thereof. The three-resistant compound microbial fertilizer is prepared from plenty, medium and trace elements nitrogen, phosphorus, potassium, compound fertilizer, paraffin, associated nitrogen fixing bacteria, phosphorus solubilizing bacteria, potassium solubilizing bacteria and bacillus such as brevibacillus laterosporus, bacillus cereus, bacillus subtilis and bacillus licheniformis by compounding. The molten liquid paraffin is used for enveloping, and the molten paraffin doped with complex microbial inoculants is used for secondary enveloping. In the invention, live microbial products are added into the conventional compound fertilizer and provide direct or indirect nutrient elements to the plants through the movement of the microbial inoculants, while improving the soil fertility, activating the soil, enhancing the stress resistance of the crops, and solving the problems of soil fertility reduction, soil hardening, nutrient unbalance and lack of stress resistance of the crops; moreover, the invention has long period of validity, resists high temperature, acid-base and dryness, is nontoxic and harmless to people and livestock, and can prevent and control pests, deal with the pieces of paddy field without lodging and obviously increase the yield.

The invention discloses a microbial agent, a preparation method thereof, and an application thereof, which relate to the technical field of microbial agent. The microbial agent includes Streptomyces albidofuscus CGMCC No.13717, Paecilomyces lilacinus CGMCC No. 13898, Streptomyces longus and mixed bacteria, wherein the mixed bacteria includes yeast, Bacillus subtilis, Bacillus licheniformis, Bacillus amyloliquefaciens, Brevibacillus laterosporus and Trichoderma harzianum. Through combination of bacteria-fungi and the synergistic effect of multi-strains, the microbial agent has the advantages ofhigh activity of strains, high efficiency and multi-functions in treating waste water, waste gas or waste. In addition, the invention also provides a preparation method of a microbial agent, which adopts a double-layer immobilization (preliminary immobilization and secondary immobilization combination) method of the microbial agent to improve the stability of the microbial agent. The preparationmethod is simple in operation and easy to be popularized and applied in industry.

The invention discloses a strain of brevibacillus laterosporus SNB10 for inhibiting riziocotinia solani. The brevibacillus laterosporus SNB10 was preserved in China General Microbiological Culture Collection Center on May 17, 2017, and the preservation number is 14171. The brevibacillus laterosporus SNB10 has the following characteristics of high inhibition effect on the riziocotinia solani and good prevention and treatment effect on rice sheath blight when being prepared into a biocontrol aqueous solution. The brevibacillus laterosporus SNB10 can produce chitinase, is wide in antibacterial spectrum, and has a certain inhibition effect on various plant pathogenic fungi and pathogenic bacteria. The brevibacillus laterosporus SNB10 does not have toxicity and pathogenicity, is safe for human and livestock, environmentally friendly, high in stress resistance and stable and durable in bacteriostatic activity, and has potential application prospect. The brevibacillus laterosporus SNB10 provides a microbial strain and a pesticide product thereof, wherein the microbial strain is non-toxic for human and livestock and friendly for the ecological environment, and has a good effect of preventing the rice sheath blight.

The invention provides a fertilizer for cultivation of tobacco. The fertilizer consists of the components by weight as follows: 0.5-1.5 parts of a composite microbial agent, 3-7 parts of an activating agent, 3-7 parts of binder, and 86-92 parts of nitrogen, phosphorus and potassium fertilizer. The effective components of the composite microbial agent are Bacillus licheniformis, Bacillus pumilus, Brevibacillus laterosporus, Bacillus megatherium and Silicate bacteria. The invention further provides a preparation method and an application of the fertilizer. The product provided by the invention can remarkably improve crumb-structure of soil for cultivation of tobacco, and microflora distribution and micro-environment of the soil. A plenty of derivatives are generated, thereby chelating or blocking damage of heavy metals, and absorption and assimilation of tobacco to nutrient elements are improved, the drought resisting and disease resisting abilities of tobacco are enhanced, damage of diseases and insects caused by continuous cropping of tobacco in successive years are effectively prevented, and in particular, tobacco mosaic virus and brown spot disease are specially prevented and treated. According to the invention, the raw materials are low in cost and easy to obtain and the preparation and using methods are simple and easy to operate.

The invention relates to a special-purpose fruit tree biological organic fertilizer and a preparation method thereof. The special-purpose fruit tree biological organic fertilizer is characterized by using 50%-65% (in percentage by weight) of fermented and cured organic matter as the material, wherein the organic matter is mixed with 10%-20% of powdered carbon, 5%-20% of shell powder, 1%-5% of seaweed meal, 1%-5% of chitin and 0.1%-0.2% of ocean brevibacillus laterosporus, bacillus subtilis and sphingomonas mixture powder (the weight ratio of the three bacteria being 1:1:1, and the number of effective microorganisms in each kilogram of the materials is 1012 or more). The special-purpose fruit tree biological organic fertilizer disclosed by the invention can be used for continuously supplying nutrients required by growth and development of the plant at each stage from the aspects including water retention, nutrition slow release and the like, can be used for improving the soil physical and chemical properties and promoting formation of soil aggregates. Most of materials used by the special-purpose fruit tree biological organic fertilizer are aquaculture by-products, so that the waste is changed into valuable, the environment-friendly effect is obvious and perpetual harms are not caused to the soil.
