Problems solved by technology

Since the compound microbial fertilizer contains live bacteria, the drying during the granulation process has a great impact on the number of live bacteria, and because peat and humic acid are mineral organic raw materials, it is more difficult to dissolve after granulation, and the granulation affects the quality of the product. and effects
However, arable land in many places in the north belongs to machine sowing, and powder products cannot be used, so they are not granulated, which directly affects the mass use and promotion of products
[0006] 3. The granulation rate of disc and drum granulation is low, the particles are irregular, and the surface is not smooth, which affects the appearance quality of the product

Embodiment 1

[0044] The avermectin waste liquid was granulated with urea to form a granular organic fertilizer. The physical and chemical properties of the sample were determined as follows:

[0045] Table 3: Basic Properties of Granular Abamectin Organic Fertilizer

[0046]

[0047] 1. Preparation of liquid bacterial agent: Bacillus subtilis (Bacillus subtilis), Bacillus megaterium (Bacillus megaterium) and gelatinous bacillus (Bacillus mucilagimosus krassilm) are fermented and produced separately by fermentation equipment, and three kinds of single bacterial liquids are prepared according to 2: The ratio of 1:1 is mixed, so that the total number of effective viable bacteria in the liquid composite microbial agent mixed with the three bacteria liquids after mixing reaches 45.2×10 8 pcs / g.

[0048] 2. Turn on the mixer, slowly and evenly add abamectin granule organic fertilizer, so that the material flows forward continuously and evenly, and use a plunger pump to spray the bacterial li...

Embodiment 2

[0051] Abamectin waste liquid in the Abamectin production process is sprayed and granulated to make Abamectin granule organic fertilizer, adding monoammonium phosphate and a small amount of 10% of the mass ratio of the finished compound microbial fertilizer in the granulation process humic acid.

[0052] 1. Preparation of liquid bacterial agent: Bacillus subtilis (Bacillus subtilis) and Bacillus megaterium (Bacillus megaterium) are fermented and produced separately by fermentation equipment, and the two single bacterial liquids are mixed according to the ratio of 1:1, so that the two bacterial liquids after mixing The total number of effective viable bacteria in the mixed liquid compound microbial agent reached 47.6×10 8 pcs / g.

[0053] 2. Turn on the mixer, slowly and evenly add avermectin granule organic fertilizer, so that the material flows forward continuously and evenly, and use a plunger pump to evenly spray the bacterial liquid on the surface of the granule organic fe...

Embodiment 3

[0056] Abamectin waste liquid in the Abamectin production process is sprayed and granulated to make Abamectin granule organic fertilizer, and 8% urea and 8% urea are added to the mass ratio of the finished product compound microbial fertilizer in the granulation process. Fertilizer mass ratio of 10% potassium sulfate.

[0057] 1. Preparation of liquid bacterial agent: Bacillus subtilis and Bacillus mucilagimosus krassilm are fermented and produced separately by fermentation equipment, and the two single bacterial solutions are mixed according to the ratio of 2:1, so that after mixing The total number of effective viable bacteria in the liquid composite microbial agent mixed with the two bacteria liquids reached 41.6×10 8 pcs / g.

[0058] 2. Turn on the mixer, slowly and evenly add granular organic fertilizer, so that the material flows forward continuously and uniformly, and use a plunger pump in the rotating mixer to evenly spray the bacterial liquid on the surface of the gra...

Abstract

The invention provides a method for producing a compound microbial fertilizer with insecticidal effect, comprising the following steps: preparing liquid microbial agent; adding waste abamectin liquid to inorganic fertilizer, and granulating the inorganic fertilizer into granular organic fertilizer; compounding the granular organic fertilizer and the liquid microbial agent which is 0.5-1.5 percent of the weight of the finished product of the compound microbial fertilizer; and airing or drying. The invention breaks the normal method for producing the compound microbial fertilizer and provides a novel method for producing the granular compound microbial fertilizer by granulating the inorganic fertilizer into the organic fertilizer and coating the liquid microbial agent by the granular organic fertilizer. The powdery compound microbial fertilizer is replaced by the granular compound microbial fertilizer, and the granular compound microbial fertilizer has a certain activity, thus a good foundation is laid for popularizing the granular compound microbial fertilizer on a large scale. The invention also provides a method for recycling the waste abamectin liquid.

Description

technical field [0001] The invention relates to a production process for producing novel high-efficiency and environment-friendly fertilizers, in particular to a method for producing granule compound microbial fertilizers by spraying and granulating waste liquid from producing abamectin. Background technique [0002] The compound microbial fertilizer has comprehensive nutrients and can improve the soil and improve the soil compaction caused by the use of chemical fertilizers. Improve soil physical and chemical properties, enhance soil water retention, fertilizer retention, and fertilizer supply capabilities. The beneficial microorganisms in the compound microbial fertilizer enter the soil and form a mutual symbiotic multiplication relationship with the microorganisms in the soil, inhibit the growth of harmful bacteria and transform them into beneficial bacteria, interact and promote each other, and play a synergistic role in the group. The beneficial bacteria grow and reprod...
