Problems solved by technology

[0005] The purpose of the present invention is to solve the shortcomings of current bio-organic-inorganic "all-in-one" compound fertilizer powder fertilizer which is easy to agglomerate, easily generates dust and causes losses and pollutes the environment, is not conducive to transportation and storage, and is inconvenient for mechanized application. The granulation process of inorganic compound fertilizer is complicated, the production cost is high, and the market promotion is difficult. A disc granulation process for producing bio-organic and inorganic "all-in-one" compound granulation fertilizer without binders has been developed.

Embodiment 1

[0036] 1. Production of bio-organic fertilizer

[0037] Inoculate Bacillus amyloliquefaciens SQR9 with the preservation number of CGMCC NO.5808 into the PDA culture medium for liquid fermentation production. The conditions for fermentation production are: the culture temperature range is 30-37 °C, and the stirring speed is 170-180 °C. revolutions per minute, spores are formed in the middle and late stages of fermentation, so that the amount of bacteria or spores in the fermentation broth is ≥ 1×10 9 pieces / ml.

[0038]Mix decomposed cow dung compost and rapeseed meal evenly according to the weight ratio of 6:4, inoculate SQR-9 fermentation broth into the mixture of rapeseed meal and decomposed cow dung compost for solid fermentation, add SQR9 fermentation broth 40~ 60L, turn the pile 1-2 times a day during the solid fermentation process, so that the solid fermentation temperature does not exceed 60°C, the fermentation ends after 6-7 days, and the SQR9 content reaches 1×10 8 ...

[0044] Example 2 Granulation test

[0045] 1 Effect of raw material powder fineness on granulation

[0046] Two " whole element " compound microbial fertilizer formulas (with formula 1 and formula 2 in embodiment 1) respectively set up four and handle a contrast, the bio-organic fertilizer after the air-drying is pulverized with hammer mill, respectively successively Use 80-mesh sieve, 60-mesh sieve, 40-mesh sieve, and 18-mesh sieve to sieve the raw materials with 80-mesh, 60-mesh, 40-mesh, and 18-mesh bio-organic fertilizer raw materials for four fineness treatments, and only use 18-mesh sieve The obtained mixed raw material was used as a control. Use formula 1 (total nutrient is 8% and only add ammonium sulfate) and formula 2 (total nutrient is 12% to add 3.82%N, 1%P respectively) 2 o 5 and 2%K 2 O) Granulation.

Abstract

Belonging to high and new agricultural technologies, the invention discloses a binder-free biological organic-inorganic ''complete element'' composite microbial fertilizer, a preparation method and application thereof. The employed fertilizer raw materials are crushed and sieved biological organic fertilizer and crushed inorganic fertilizer. The biological organic fertilizer adopts the strain Bacillus amyloliquefaciens SQR-9; and adopted the fertilizer can be ammonium sulfate, calcium superphosphate and potassium chloride. The technological process includes: mixing the raw materials evenly according to a nutrient demand proportion, adding the mixture into a disc granulator, carrying out intermittent spray granulation and screening, and finally performing drying at a temperature of less than or equal to 50DEG C to a moisture mass ratio of less than 20%, and conducting packaging, thus obtaining the commodity biological organic-inorganic ''complete element'' composite microbial fertilizer. The process greatly reduces the production cost of the biological organic-inorganic fertilizer, the operation is simple, the fertilizer granulation rate is good, and the granulation efficiency is high.

Description

technical field [0001] The invention relates to a bio-organic-inorganic "all-element" compound microbial fertilizer without binder, a preparation method and application thereof, belonging to the field of agricultural high-tech. Background technique [0002] Some developed countries entered the stage of agricultural modernization in the 1920s, and my country began to enter the stage of agricultural modernization in the 1960s—the conventional agricultural modernization development model of "high input, high output, and high pollution", which greatly improved the level of agricultural production, but At the same time, it has also led to extreme consumption of resources, serious damage and pollution of the ecological environment. In my country, due to the long-term and unreasonable application of large quantities of chemical fertilizers, the slow effect of organic fertilizers, the serious shortage of application area and dosage, the low efficiency of biological bacterial fertiliz...
