Production method of organic farmyard manure

Abstract

The invention discloses a production method of organic farmyard manure and relates to the technical field of fertilizer. The production method includes: building a seepage-preventing storage tank, a stirring tank, a fermentation tank and a liquid excrement storage tank, and building rain-proof sheds over the tanks; mounting the matched crusher, hay cutter, stirring machine, turning conveyor and beating equipment; collecting daily kitchen waste and livestock and human excrement, sorting the kitchen waste and livestock and human excrement, crushing the sorted kitchen waste and livestock and human excrement in a unified manner, beating, and storing; recycling non-degradable waste such as plastic and glass, and arranging and packaging for centralized selling; mixing the crushed straw, kitchenwaste and livestock and human excrement with corrosives and nitrogen phosphorus and potassium compound fertilizer according to a certain weight proportion to produce the organic farmyard manure. The production method has the advantages that the straw, livestock and human excrement and household waste are used as the main production raw materials, the daily garbage and straw can be recycled, energyis saved, the blank of fertilizer for green industry development can be filled up, and the use amount of chemical fertilizer is reduced to the maximum extent.

Description

Technical field: [0001] The invention relates to a production method of organic farm fertilizer, which belongs to the technical field of fertilizers. Background technique: [0002] The survey found that more than 90% of the existing basic arable land has not been sown and applied with organic manure for nearly 40 years. As a result, the farmland soil is extremely poor, nutrients are exhausted, mineralization is serious, and the water retention performance of solid fertilizers is reduced. The reasons for problems such as weak resistance are: the transfer of young, strong, and labor forces in rural areas, and farming production is replaced by old, weak, and women. In order to reduce labor intensity, the traditional operation mode of collecting manure has been abandoned, and chemical fertilizers have been applied for a long time. Another important aspect caused by the incremental increase is that the price of organic fertilizers on the market is generally high, and the basic fa...

[0002] The survey found that more than 90% of the existing basic arable land has not been sown and applied with organic manure for nearly 40 years. As a result, the farmland soil is extremely poor, nutrients are exhausted, mineralization is serious, and the water retention performance of solid fertilizers is reduced. The reasons for problems such as weak resistance are: the transfer of young, strong, and labor forces in rural areas, and farming production is replaced by old, weak, and women. In order to reduce labor intensity, the traditional operation mode of collecting manure has been abandoned, and chemical fertilizers have been applied for a long time. Another important aspect caused by the increase is that the price of organic fertilizers on the market is generally high, and the basic farmland is simply unable to afford it. As a result, farmers have no choice but to use chemical fertilizers
