摘要
在冬小麦—夏玉米种植区,为避免小麦留茬免耕直播夏玉米出现肥害,设计试验了不同施肥方法。研究认为,夏玉米铁茬播种在播种施肥机械还做不到种、肥有效隔离的情况下,播种时不施底肥,只用种肥,配合早期追肥是安全有效的施肥方法。
In winter wheat-summer maize rotation system, different fertilization treatments were designed for studying the effect of wheat stubble on non-tillage seeding com. The results showed that it was effective fertilization way that no basal fertilizer, but seed manure and top-dressing in early stage was used, if seed and fertilizer could not be effectively separated by seeding and fer- tilization machine when summer maize was directly seeded.
