玉米秸秆是培肥土壤的主要材料。有人认为玉米秸秆直接还田不如堆沤后还田效果好.我们就这一问题,进行了玉米秸秆堆腐与直接还田的比较研究。我们利用田间微区和盆栽配合进行两年试验,以非腐解态(按亩施250公斤风干玉米秸秆)和腐解态(亩施250公斤风干玉米秸秆加水自然腐解)为处理,以不施玉米秸秆为对照,说明以下三点:
Corn stalks are the main material for fertilizing soil. Some people think that the direct return of corn stalks is better than the return of stubble after the effect is good.We have on this issue, corn stalks heap and direct comparison of the study. We use the field micro-area and potted plants for two years with non-decomposed state (mu kilograms of air-dried corn stalks) and decomposed state (mu of 250 kg of air-dried corn stalks and natural decomposition of water to deal with) Shi corn straw as a control, indicating the following three points:
