研究不同秸秆腐熟剂品种在玉米秸秆还田模式下的使用效果及对玉米生长性状、产量和土壤理化性状的影响,结果表明在重庆市江津区玉米生产中,在常规施肥基础上秸秆还田可改善土壤理化性状,增加土壤养分含量;同时秸秆还田加合适的腐熟剂还可增加玉米每穗籽粒数和千粒重,从而提高玉米产量;本次试验中腐熟剂效果最好的是品种2(扬州博轩),其次是品种3(成都华隆)。
The effects of different straw maturity varieties on the corn stalks return pattern and its effects on the growth traits, yield and soil physical and chemical properties of maize were studied. The results showed that in the production of corn in Jiangjin District of Chongqing, on the basis of conventional fertilization, Improve soil physical and chemical properties, increase soil nutrient content; while straw addition of appropriate maturity agent can also increase the number of grains per panicle and 1000-grain weight, thereby increasing the yield of corn; The best effect of this trial is the variety 2 (Yangzhou Bo Xuan), followed by Variety 3 (Chengdu Hualong).
