Compound organic fertilizer and preparation method thereof

Abstract

According to the compound organic fertilizer and the preparation method thereof, the livestock and poultry manure, the straw powder and the caragana microphylla powder are selected as raw materials, the raw materials are decomposed into the fertilizer rich in micromolecular organic matter through the steps of steam explosion, compost fermentation and the like, nutrients are balanced, fertility is lasting, and growth and development of plants can be effectively promoted after the compound organic fertilizer is applied. Meanwhile, bentonite, rectorite powder, coco coir, humic acid, a water-retaining agent, chitosan and other raw materials are further added into the fertilizer, the composite organic fertilizer with the particle size of 3-5 mm is prepared through mixing granulation, agricultural waste resources are utilized, the application amount of the chemical fertilizer is reduced, ecological damage and environmental pollution caused by excessive application of the chemical fertilizer are avoided, and a good ecological cycle is formed; meanwhile, agricultural travel income increase can be achieved, and agricultural sustainable development is promoted.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and particularly relates to a compound organic fertilizer and a preparation method thereof. Background technique [0002] Chemical fertilizer is an important agricultural production material and plays an irreplaceable role in the development of agricultural production. However, repeated continuous cropping and unreasonable use all year round can easily cause problems such as soil compaction, soil fertility decline, ecological damage, environmental pollution and the quality of agricultural and sideline products. . Organic fertilizers are mainly prepared from animal and plant residues such as livestock and poultry waste, crop straws and other animal and plant residues through harmless treatment and decomposing. After the soil, organic matter can effectively improve the physical and chemical conditions and biological characteristics of the soil, mature the soil, enhance the ability of soil to r...

AI Technical Summary

Problems solved by technology

[0003] However, in the production process of traditional organic fertilizers, there is no reasonable allocation of raw materials and processing and screening, which cannot guarantee the quality and reliability of raw materials; or the ratio is purely based on plant materials or animal manure materials, and the fertility is single; Or, the production process is complicated, and the types and methods of adding bacteria often lead to high production costs, which push up the burden of agricultural production too high, etc.
