一、草灰垫栏圈,损钾又失氮草木灰是农家肥中最重要的钾肥资源;厩肥(各种牲畜栏肥)是农村普遍使用的有机肥。在农村,仍有不少农户习惯用草木灰作垫圈材料来积造厩肥,这是很不科学的。因为草木灰呈碱性,能加速牲畜粪尿中氮的挥发,造成氮素的损失;又因为草木 First, the grass ash pad column, loss of potassium and nitrogen loss of ash is the most important source of potash fertilizer; manure (a variety of livestock column barley) is a common organic fertilizer in rural areas. In rural areas, many farmers still use grass and ash as a gasket material to build manure, which is not scientific. Because ash is alkaline, can accelerate the volatilization of nitrogen in livestock excrement, resulting in the loss of nitrogen; and because vegetation
