example 1

[0037] Each ton of the compound microbial bacterial fertilizer of the present invention contains 125kg of monoammonium phosphate, 150kg of potassium chloride, 130kg of urea, 310kg of ammonium chloride, 180kg of organic matter, 70kg of microbial bacterial agent, 25kg of binder, 3.5kg of zinc sulfate, and Magnesium 3kg, ferrous sulfate 2.5kg, plant growth regulator 1kg.

[0038] The above-mentioned biological bacteria agent includes Bacillus subtilis, Paenibacillus jelly-like and Bacillus amyloi, and the ratio of parts by weight of Bacillus subtilis, Paenibacillus jelly-like and Bacillus amyloi is 8:1:1.

[0039] The process steps of the above-mentioned composite microbial bacterial fertilizer preparation process are as follows:

[0040](1) Sterilization of raw materials: Sterilize the above-mentioned components according to the ratio to obtain non-polluting raw materials; (2) Crushing: transport the non-polluting raw materials to the crusher for crushing; (3) Stirring: transpor...

example 2

[0042] The difference between Example 2 and Example 1 lies in the amount and selection of each component. The specific differences are as follows: every ton contains 135kg of monoammonium phosphate, 180kg of potassium sulfate, 150kg of urea, 320kg of ammonium sulfate, 90kg of organic matter, 115kg of microbial inoculum, and 3.5kg of zinc sulfate , magnesium sulfate 3kg, ferrous sulfate 2.5kg, plant growth regulator 1kg. Its preparation process is consistent with Example 1, so omitted.

example 3

[0044] The difference between Example 3 and Example 1 lies in the amount and selection of each component, and the specific differences are as follows: every ton contains 135kg of monoammonium phosphate, 80kg of potassium chloride, 80kg of potassium sulfate, 150kg of urea, 145kg of ammonium chloride, 145kg of ammonium sulfate, and 100kg of organic matter , 65kg of microbial agent, 3.5kg of zinc sulfate, 3kg of magnesium sulfate, 2.5kg of ferrous sulfate, and 1kg of plant growth regulator. Its preparation process is consistent with Example 1, so omitted.

[0045] The main technical indicators of the finished fertilizer of the present invention (subject to the general type) (1) Granularity, granular 2.0-4.0mm; (2) Appearance black or dark brown, with a slight smell; (3) The number of effective viable bacteria ≥ 2.0×10 7 cfu / g, the number of single effective viable bacteria ≥ 1.0×10 6 cfu / g; (4) pH value 6-8; (5) Moisture content 7-12%, mixed bacteria rate <20%; (6) Average parti...

Abstract

The invention discloses a compound biofertilizer. The compound biofertilizer is characterized by comprising the following components in percentage by weight: 9-18% of soil organic matter, 1-2% of a plant growth regulator, 6-12% of a microbial agent and the balance of chemical elements required for the plant growth. The preparation technology of the compound biofertilizer is characterized in that a twice sectional-type baking technology is adopted so as to guarantee that the condition the activity of the biofertilizer is lowered due to the high-temperature process is avoided. According to the invention, soil can be provided with beneficial microorganisms and the required nutritional elements by the compound biofertilizer, and the microorganism activity of soil can be enhanced, so that the fertility of soil can be improved; the pesticide residue can be degraded; the quality and stress resistance of crops can be improved; the physical character of soil can be improved.

Description

technical field [0001] The invention belongs to the technical field of microbial fertilizers, in particular to a compound microbial fertilizer. Background technique [0002] At present, our country is undergoing the sixth change of food culture, which is shifting from consuming caloric food to consuming safe and nutritious food, and paying more attention to food safety. In recent years, with the improvement of living standards, people's demand for pollution-free green food is also increasing. It is foreseeable that pollution-free microbial fertilizers will play an important role in future agricultural production. [0003] Microbial fertilizer, also known as bacterial fertilizer, biological fertilizer, inoculant, etc., is a kind of product that gives crops a specific fertilizer effect due to microbial life activities. It is a compound biological fertilizer made of effective fungi and adsorption materials. In agricultural production, crops can obtain specific fertilizer effe...
