堆肥的酦酵腐熟,是微生物活动的结果。微生物在分解有机质的过程中,需要吸取一定量的氮素作为养料;因此使堆肥保持适当的碳氮此例,是保证酦酵过程顺利进行的重要条件。一般植物性的堆肥材料(豆科植物除外),氮素含量较低,需要加进一些含氮量高的物质来调节碳氮此例。粪尿是通常用来调节碳氮此例的物质,但粪尿是农村中一项重要的肥源,农民对粪尿的使用很珍惜,而大豆是各地广泛栽培的作物,大豆收获以后遗留下的豆壳不少,豆壳里含有多量的氮素,为探求将豆壳加入堆肥,是否可以代替 Fermented compost composting, is the result of microbial activity. Microorganisms in the process of decomposition of organic matter, need to draw a certain amount of nitrogen as a nutrient; Therefore, the compost to maintain proper carbon and nitrogen in this case, is to ensure the fermentation process is an important condition for the smooth. The general plant compost material (except legumes), nitrogen content is low, you need to add some high nitrogen content of substances to regulate carbon and nitrogen in this case. Excreta is a substance commonly used to regulate carbon and nitrogen in this case, but excreta is an important source of fertility in rural areas. Farmers value the use of excreta, and soybeans are widely cultivated throughout the country. A lot of beans shell, beans contain a lot of nitrogen in the shell, in order to explore the addition of soybean shell compost, whether it can replace
