作物秸秆作为能量和营养成分的载体,是一种宝贵的生物资源,除直接为人们利用,作为造纸工业及农村燃料外,大部分秸秆用来作为饲料养畜,“过腹还田”。但目前由于受畜牧业发展的限制,还不可能将剩余的秸秆全部“过腹还田”,大量的秸秆被浪费,既占压耕地,影响环境卫生,又是农村火灾的一大隐患。 按照推广秸秆还田,增加土壤有机质,改良土壤,解决环境污染的思路,为探索和寻求秸秆还田的新方法,1996年,省土肥站、民勤县农技中心和兰州大学有关专家共同协作研究,选育出了一种腐生性极强的高温
As a carrier of energy and nutrients, crop straw is a precious biological resource. Apart from being directly used by people and used as paper industry and rural fuel, most of the straw is used as feed for raising livestock and “returning belly to the field”. However, due to the restriction of the development of animal husbandry, it is impossible for the remaining straws to be “rehabilitated” and a large amount of straw is wasted. It not only occupies the cultivated land but also affects the environment and sanitation. It is also a major hazard for rural fires. In 1996, the provincial soil fertilizer station, Minqin County Agricultural Technology Center and Lanzhou University experts to work together to promote the return of straw to soil, increase soil, solve environmental pollution ideas, Research, breeding a highly satiated high temperature
