Composting method of agricultural waste such as rotten vegetable leaves and straw

Abstract

The invention discloses a composting method of agricultural waste such as rotten vegetable leaves and straw. By utilizing a powerful decompression and dehydration effect and a multifunctional composite membrane technology of modern machinery, high-water content vegetable waste and cellulose-enriched straw waste are fully mixed, and original organic matters can be converted into humus through fermentation by utilizing static composting; due to a microporous structure of a functional membrane, water desorption during a fermentation process is prevented, so that moisture during a fermentation process is relatively constant, meanwhile, ammonia is reserved to the maximum, and the content of nitrogen element in compost is increased; meanwhile, the environment cannot be influenced in relatively airtight sealing environment.

Description

technical field [0001] The invention relates to waste treatment after harvesting crops, in particular to a method for composting agricultural waste such as tail vegetables and straws. Background technique [0002] Every year, vegetable planting and grain planting in our country will produce a large amount of agricultural waste such as tail vegetables and straws in the harvesting process. If they are discarded at random, the fields will easily corrupt and cause soil and water pollution, and they will be piled up randomly to occupy a large amount of land; if these discarded If the waste is directly returned to the field by rotary tillage, because the organic matter, especially the straw, ferments slowly in the soil, a large number of spoilage bacteria will grow, which will affect the germination of seeds and the normal growth of plant roots. Moreover, a large amount of organic acids will be produced during the fermentation process of waste, which will change the pH environment ...

Moreover, a large amount of organic acids will be produced during the fermentation process of waste, which will change the pH environment of the soil. , with the increase of soil cellulose and sugar, the large number of diseases and insect pests will cause serious problems such as the threat of crop growth in the coming year
