用草木灰代替石灰制造高温酦酵堆肥今年8月下旬江苏涟水农场用玉米秆12,000斤制造堆肥,因鉴于往年用秸秆沤肥,腐熟程度不够,不但不能发挥应有的肥效,而且,由于酦酵温度不够(最高40℃),不能杀死秸秆中混杂的病菌、草籽。另外,老式堆肥也无法使玉米秆腐烂。因此,我们学习了农业科学通讯上所介绍的“牛坑式通风性高温酦 In late August of this year, Jiangsu Lianshui Farm made compost with 12,000 kg of corn stalks. In view of the inadequate maturity of straw with straw in previous years, it not only failed to exert its proper fertilizer efficiency, but also, due to the fermentation temperature Not enough (up to 40 ℃), can not kill the mixed bacteria in the straw, grass seeds. In addition, the old composting can not make corn stalks rot. Therefore, we have studied the agricultural science communication introduced ”beef pit ventilation high temperature 酦
