Problems solved by technology

For the current rural grain harvest, the main treatment of a large amount of straw and straw is nothing more than incineration, which not only wastes a lot of natural fertilizer resources, but also causes secondary air pollution to the ecological environment

Embodiment Construction

[0011] 1. Weighing

[0012] Weigh 70-80kg of livestock and poultry manure with a water content of 40-60% and 20-30kg of straw with a particle size not greater than 10mm.

[0013] 2. Stirring

[0014] Firstly, the animal manure and the crushed straw are stirred and mixed.

[0015] 3. Stacking anaerobic fermentation

[0016] Mix livestock and poultry manure and straw for 3-5 minutes, then stack, and cover the stack with plastic film, anaerobically ferment for 15-20 days under the condition that the internal temperature of the stack is 90-95°C, and then turn the stack Stack again, cover the stack with plastic film, anaerobically ferment for 15-20 days under the condition that the internal temperature of the stack is 70-80°C, then turn the stack and stack again, cover the stack with plastic film, Ferment for 40-50 days under the condition that the internal temperature of the stack is 70-80°C.

[0017] The material to be mixed is corroded or carbonized until there is no abnorma...

Abstract

The invention provides a method for producing an organic fertilizer by using rice straws and livestock and poultry manures, and relates to the technical field of an organic fertilizer production process. According to the method, livestock and poultry manures and crushed straws are stirred, and subjected to stacking anaerobic fermentation, crushing, and packaging to prepare the organic fertilizer. According to the present invention, characteristics of water absorption, deterioration, and the like of the waste rice straws are mainly adopted; during the organic fertilizer production process, a large amount of the waste rice straws can be added before the livestock and poultry manures are subjected to dewatering and fermentation so as to increase dewatering efficiency, accelerate deterioration process, and further increase organic matter content after humic improving; and the method of the present invention has characteristics of relatively available raw material, low energy consumption, and low investment, and provides an important means for sustainable agriculture development.

Description

technical field [0001] The invention relates to the technical field of production technology of organic fertilizers. Background technique [0002] In recent years, the input of agricultural inorganic fertilizers has become less and less with the long-term and large-scale polluting application of chemical fertilizers, which has inevitably aggravated soil compaction, salinization and environmental pollution. For the current rural grain harvest, the main treatment of a large amount of straw and straw is nothing more than burning, which not only wastes a lot of natural fertilizer resources, but also causes secondary air pollution to the ecological environment. Contents of the invention [0003] The invention is dedicated to the research, development, production and popularization of a new type of environmentally friendly pure natural organic agricultural fertilizer, a method for producing organic fertilizer with stalks, straw and livestock and poultry manure, which can turn wa...
