Method for locally producing in-situ organic fertilizer in crop straw field and application

Abstract

The invention provides a method for locally producing an in-situ organic fertilizer in a crop straw field and an application. The method is achieved by the following steps of: crushing crop straws when crops are harvested; adding suitable amount of livestock excrement, urea or ammonium sulfate; inoculating suitable amount of cellulose decomposing bacteria, lignin decomposing bacteria and the like; agitating uniformly and filling water; keeping a field wet state for about 14 days in summer and about 12 days in autumn; and rapidly changing the crop straws into a high-quality organic fertilizer in farmland soil by biological catalytic conversion. Then grains and vegetables can be planted and environmental pollution is avoided; air pollution caused by combusting the crop straws is solved, the problem that organic matters of the farmland soil are reduced is solved, and the soil fertility is improved, so that the development of ecological agriculture is promoted; and the method is simple and feasible, saves the one-time huge investment of commercial production, saves energy and reduces emission, greatly reduces the labor intensity and solves the problems of long-distance transportation, secondary pollution and the like.

Description

[0001] technical field [0002] The invention belongs to the fields of agricultural technology and environmental protection, and in particular relates to a method and application for producing in-situ organic fertilizer from crop stalks in the field. [0003] Background technique [0004] In 2009, the National Development and Reform Commission and the Ministry of Agriculture jointly issued a document requiring all localities to accelerate the comprehensive utilization of straw, gradually form a virtuous circle of straw resource development and utilization, realize the commercialization and recycling of straw, and promote the construction of a resource-saving and environment-friendly society. my country's crop stalks have a large quantity, variety and wide distribution. They are the main living fuel for rural residents, feed for large livestock and organic fertilizers. A small part of them are used as industrial raw materials and base materials for edible fungi. However, the...

Problems solved by technology

[0006]Technical problem to be solved: the present invention aims at the problems of air and water pollution and waste of resources caused by a large amount of crop stalks that cannot be processed correctly and in time, and develops a simple and easy method, Provided is a method and application of in-situ organic fertilizer production from crop stalks in the field. The method is that after the crops are harvested, the crop stalks are crushed into grass segments, and livestock and poultry manure, urea, ammonium sulfate, quicklime, and Trichoderma are added. , Penicillium, Aspergillus, Actinomycetes, Coriolus maugeria, Streptomyces, Arthrobacter, Pseudomonas, Xanthomonas, etc., the soil in-situ organic fertilizer made by mixed fermentation in the field is applied to the farmland as a base fertilizer , plant crops, develop organic agriculture and ecological agriculture, improve and increase soil productivity, promote crop growth, reduce environmental pollution, save energy and reduce emissions, improve crop quality, increase crop yield, and increase farmers' economic benefits
