MY preparation bio-organic fertilizer and preparation method thereof

Abstract

The invention provides an MY preparation bio-organic fertilizer and a preparation method thereof, and relates to the technical field of organic fertilizers. The method comprises the following steps: providing raw materials including animal waste, weathered coal, plant branches and straws, and pretreating the raw materials to obtain pretreated raw materials including ammonia nitrogen lignin, activated humic acid and pretreated animal waste; preparing ammonia-nitrogen lignin, activated humic acid, vitamins, wood tar and pyroligneous liquor into an MY biological agent, mixing and stirring the MY biological agent and pretreated animal waste, and performing stack retting decomposition and drying granulation to obtain organic fertilizer, wherein the organic fertilizer is applied and sown under various soil conditions and is environmentally friendly and efficient; the prepared organic fertilizer can significantly improve soil, increase effective nutrients, improve the utilization rate of the fertilizer, improve the water and fertilizer absorption capacity of plant roots, stimulate crop growth, increase yield and improve quality, does not need to be added with microbial agents and straw, avoids conditions necessary for survival of microbial florae, reduces the production cost, is short in preparation period and small in occupied area, and facilitates the industrial production.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to a MY preparation bio-organic fertilizer and a preparation method thereof. Background technique [0002] With the rapid development of industrial and agricultural production, my country's intensive and large-scale breeding industry has developed rapidly, which has produced huge social and economic benefits, and also produced a large amount of livestock and poultry manure waste. If these wastes are not handled properly, it will destroy the ecological balance, affect the safe production of livestock and poultry and the food safety of people. According to statistics, the annual production of animal feces in my country has reached nearly 2 billion tons, but the utilization rate is only 1 / 5. Increase. Manure is indeed a good fertilizer, but if it is used without treatment, once it flows into the river, the nitrogen and phosphorus contained in the manure will pollute the ri...

AI Technical Summary

Problems solved by technology

Manure is indeed a good fertilizer, but if it is used without treatment, once it flows into the river, the nitrogen and phosphorus contained in the manure will pollute the river and groundwater, and the salt and antibiotics in the manure will also damage the soil. pollution, causing deterioration of the ecological environment

[0003] The existing farmyard manure made from animal manure generally adopts methods such as sun drying, fire roasting, composting, anaerobic fermentation, and adding microbial agents. Harmful gases such as methane damage the germination and rooting of crops, increase heavy metals and toxic elements, and cannot decompose harmful salt in animal manure, thereby greatly reducing the fertilizer efficiency of organic fertilizers, and will also produce serious odors and pollute the environment

The organic fertilizer manufactured by factory using feces as raw materials requires a large amount of straw, crushed plants and brown sugar water to multiply the microbial flora during the production process, and the fermentation time is long, and the growth and reproduction of the microbial flora is harmful to the outside world. Environmental conditions are relatively strict, making it difficult to control the survival and survival of microbial flora, which increases the production cost of organic fertilizers and is not conducive to industrial production
