Embodiment 1

[0034] The embodiment of the present invention provides a compound microbial fertilizer with drought resistance and pest resistance and its preparation method, including organic fertilizer, microbial strains and inorganic nutritional raw materials. The organic fertilizer is composed of a mixture of pig manure and crop straw, and the type of microbial strain is spores Bacillus, silicate bacteria and rhizobia, and the ratio is 1:0.5:1. Bacillus reproduces quickly, has the characteristics of inhibiting the growth and reproduction of harmful bacteria and has strong moisture retention. Silicate bacteria have strong adaptability to reproduction in soil , inhibit the growth of other pathogenic bacteria, and at the same time have a good effect on crop growth, yield increase and quality improvement. Rhizobium has a strong nitrogen fixation effect and can promote crop growth. The weight ratio of organic fertilizer and microbial strains is 70% 1 part of pig manure and crop stalk mixture, ...

Embodiment 2

[0036] The embodiment of the present invention provides a compound microbial fertilizer with drought resistance and pest resistance and its preparation method, including organic fertilizer, microbial strains and inorganic nutritional raw materials. The organic fertilizer is composed of a mixture of pig manure and crop straw, and the type of microbial strain is spores Bacillus, silicate bacteria and rhizobia, and the ratio is 1:0.5:1. The ratio is simple and reasonable, and rapid cultivation can be achieved. The joint action of Bacillus, silicate bacteria and rhizobia makes the compound microbial fertilizer have drought and The effect of insect pests, the organic fertilizer and the various components of the microbial strains are 90 parts of pig manure and crop straw mixture, 8 parts of the microbial strains, and the components of the inorganic nutritional raw materials are 0.5 parts of borax, 0.15 Part zinc sulfate, 0.3 part calcium carbonate, 0.4 part ammonium phosphate, 0.15 p...

Embodiment 3

[0038] A preparation method of a compound microbial fertilizer with drought resistance and pest resistance, comprising the following steps:

[0039] Sp1: Organic fertilizer decomposed and composted

[0040] The organic fertilizer is placed in a closed environment for decomposing, and the leachate is extracted at a temperature of 50-60°C for 6-10 days. The decomposed organic fertilizer is placed in a crushing device for preliminary crushing;

[0041] Sp2: Mixing treatment of inorganic nutritional raw materials

[0042] Add borax, zinc sulfate, calcium carbonate, ammonium phosphate, potassium chloride, manganese sulfate, potassium sulfate, copper sulfate, titanium dioxide and sodium molybdate into the mixing tank in sequence, then add the leachate produced by organic fertilizers to fully stir, and use High-temperature heating and ultraviolet irradiation are used to sterilize and inactivate. The method of high-temperature heating and ultraviolet irradiation can prevent other bac...

Abstract

The invention provides a composite microbial fertilizer with drought resistance and insect pest resistance and a preparation method thereof, and relates to the field of microbial fertilizers. The composite microbial fertilizer with drought resistance and insect pest resistance comprises an organic fertilizer, microbial strains and inorganic nutritional raw materials, the organic fertilizer is composed of a mixture of pig manure and crop straw, and the microbial strains are bacillus, silicate bacteria and rhizobium in a ratio of 1: 0.5: 1. The organic fertilizer comprises the following components in parts by weight: 70-90 parts of a mixture of pig manure and crop straw and 5-8 parts of microbial strains. The inorganic nutritional raw materials comprise the following components in parts by weight: 0.25-0.5 part of borax, 0.05-0.15 part of zinc sulfate, 0.15-0.3 part of calcium carbonate, 0.2-0.4 part of ammonium phosphate, 0.05-0.15 part of potassium chloride, 0.01-0.02 part of manganesesulfate, 0.1-0.3 part of potassium sulfate, 0.01-0.03 part of copper sulfate, 0.02-0.04 part of titanium dioxide and 0.2-0.35 part of sodium molybdate. Bacillus, silicate bacteria and rhizobium are adopted to obviously enhance the utilization ratio of the fertilizer, and the fertilizer has the effects of disease prevention, insect prevention and drought resistance.

Description

technical field [0001] The invention relates to the technical field of microbial fertilizers, in particular to a compound microbial fertilizer with drought resistance and pest resistance and a preparation method thereof. Background technique [0002] Microbial fertilizer is a biological fertilizer produced by one or several kinds of beneficial microorganisms through industrialized cultivation and fermentation, which can promote the absorption and utilization of nutrients by plants, or can resist the pathogenic effect of certain pathogenic microorganisms, reduce pests and diseases, thereby improving Crop yield and quality. [0003] In the existing microbial fertilizer, the organic fertilizer used by microorganisms has a low NPK content, and other strains may be mixed in the production and preparation process. At the same time, it has poor performance in terms of drought resistance and pest resistance. Therefore, a drought-resistant and pest-resistant fertilizer is proposed. ...
