本刊连环书介绍了高温速成堆肥的制造法,可以在短期间沤熟不易腐烂的秸秆。现在把这个方法的好处和道理说明如下:华北农业生产上一个很大的障碍是土壤中缺乏有机质——动植物腐烂后与土壤结合的粽黑色物质。因而土壤的结构破坏,板结变硬,保温保墒的能力很差。其中的微生物数量很少,农作物不能按照自己的需要吸收土壤中的养份。对于病虫自然灾害抵抗力很弱,严重的威胁若我们的农业生产。目前群众使用的粗肥如圈粪、秸秆粪等是有机质
Our series of books describes the manufacturing method of high-temperature rapid compost, can be cooked in a short period of non-perishable straw. The benefits and rationale of this method is now explained as follows: A major obstacle in agricultural production in North China is the lack of organic matter in the soil - black matter that binds to the soil after the decay of plants and animals. Thus the destruction of soil structure, harden plate, the ability to keep moisture is very poor. The number of microorganisms in them is very small and crops can not absorb the nutrients in the soil according to their needs. Resistance to pests and natural disasters is weak, a serious threat if our agricultural production. At present, the masses used crude fat such as stool, stool, etc. are organic matter
