Problems solved by technology

However, the current aerobic fermentation treatment method alone cannot degrade the residues in the abamectin fermentation waste residue. Therefore, using the existing technology, it is impossible to use the abamectin fermentation waste residue to produce bio-organic fertilizers that meet the requirements of environmental safety standards.

Embodiment 1

[0019] Embodiment 1. preparation of Abamectin degrading bacterial agent

[0020] 1) The abamectin-degrading bacteria AZ11 slant-preserved test tube seeds were inoculated into LB liquid medium, and shaken at 40-45°C until the logarithmic growth phase;

[0021] 2) Inoculate the cultured bacterial solution into a 10L seed fermenter with 10% inoculation amount, and cultivate it at 40-45°C until the logarithmic growth phase. The cultivation and formula of the seed fermenter are: corn flour 2%; bean cake powder 1 %; Glucose 0.5%; K 2 HPO 4 0.4%; MgSO 4 ·7H 2 O 0.02%; CaCO 3 0.2%; pH 7.2-7.5;

[0022] 3) Inoculate the fermented liquid of the seed fermenter with 10% inoculum into the production fermenter for fermentation production. The medium formula used in the fermentation production is: corn flour 3%; bean cake flour 2%; CaCO 3 0.5%;K 2 HPO 4 0.2%; ZnSO 4 ·5H 2 O 0.05%; MgSO 4 ·7H 2 O 0.05%; pH 7.2;

[0023] The fermentation production process conditions...

Embodiment 2

[0025] Embodiment 2. Abamectin fermentation waste residue bio-organic fertilizer preparation

[0026] According to the weight ratio of 50% of abamectin waste residue, 40% of straw, and 10% of chicken manure, the composition of the pile is prepared, and water is added until the water content is 60%, and stirred evenly; refer to the size of the fermentation site, and the length of the pile is 10.0 meters, and the width is 8.0 meters. , with a pile height of 1.5 meters; after the pile temperature rises to 40°C, inoculate the degrading bacteria agent weighing 1% of the total weight of the raw materials (dry weight) on average twice, with an interval of 4 days; use fully automatic fermentation every 3 days Turn the pile once with the mixer, ventilate for 1.5 hours every 12 hours, and ferment for 24 days. When the pile temperature drops below 40°C, the high-temperature fermentation process is over, and the residue of abamectin in the pile is detected; at this time, the fermentation m...

Embodiment 3

[0027] Embodiment 3 The screening of the preparation process condition of bio-organic fertilizer of the present invention, preferred test

[0028] The test method is to change one process condition, fix the other conditions (not necessarily the optimal point), conduct a fermentation test, and evaluate the optimal process parameters by measuring the degradation rate of abamectin waste residue.

[0029] 1) Determination of the inoculum amount of degrading bacteria

[0030]After the stacking temperature naturally rises to 40°C, inoculate the degrading bacteria agent at 0.1%, 0.5%, and 1% inoculum respectively, and set a control without inoculation, turn the stack once every 3 days with a fully automatic fermentation mixer, and detect Avi The remaining amount of mycocin is fermented until the pile temperature is below 40°C.

[0031] The results showed that adding the degrading bacteria agent could significantly improve the degradation of abamectin in the pile. At the end ...

Abstract

The present invention provides a method for producing a biological organic fertilizer from abamectin fermentation waste residue. A main raw material of abamectin fermentation waste residue and auxiliary blending materials of straw and chicken manure are treated with aerobic fermentation; an abamectin residue degradation microbial inoculum is added during the aerobic fermentation process to help accelerating degradation of the abamectin residue, under high temperature, ventilating and aerobic conditions. Field tests show that the biological organic fertilizer prepared by the method provided by the invention can not only substitute a conventional biological organic fertilizer to be used in agricultural production, but also has obvious yield increasing effect, so as to realize harmlessness and resource utilization of the avermectin waste residue compost.

Description

technical field [0001] The invention belongs to the technical field of agricultural biology, and relates to a bio-organic fertilizer produced by using abamectin fermentation waste residue and a preparation method thereof. Background technique [0002] According to statistics, my country produces billions of tons of industrial and agricultural solid waste every year, and more than 10 million tons of hazardous waste, posing a threat to ecological and environmental security and becoming an important source of pollution. Antibiotic fermentation waste pollution has become a top priority. Residual antibiotics can cause drug residues in products or drug resistance of environmental microorganisms, causing potential harm to human health. In addition, antibiotics ingested by animals are discharged into soil or water through feces and urine, which destroys the micro-ecological balance of the environment. If the untreated antibiotic dregs are fertilized in the form of fertilizer, it wi...
