以新麦26为试材，采用3年定点大田试验研究玉米秸秆还田与氮肥、秸秆腐蚀剂及精制鸡粪配施对冬小麦群体、产量结构及产量的影响。结果表明：在玉米秸秆全部还田情况下，冬小麦群体有随着施氮量的增加而增多的趋势；千粒重变化不明显；穗粒数和产量的变化相一致，随着施氮量的增加而提高，但在666．7m2施纯N 13 kg＋精制鸡粪100 kg和施纯N 13 kg＋腐蚀剂150 g处理情况下，其产量和千粒重与分别单施纯N 16、19 kg的处理相近。综合考虑生产成本，试验地区666．7m2宜施纯N 13 kg＋腐蚀剂150 g。

Three-year field experiments in fixed location were conducted to study the effects of corn straw returning combined with nitrogen fertilizer , straw corrosive or refined chicken manure on population , yield and its components of wheat with Xinmai 26 as material.The results showed that in the condition of re-turning all corn straw , the wheat population showed a increasing trend with the increase of nitrogen application amount , while 1 000-grain weight had no obvious change .The change of grain number per spike was consist-ent with that of yield ,which increased with the increase of nitrogen application amount .Under the treatments of 13 kg nitrogen+100 kg refined chicken manure per 666.7m2 or 13 kg nitrogen+150 g corrosive, the wheat yield and 1 000-grain weight were similar to those of single application of 16 or 19 kg nitrogen .Considering the production cost , the combined application of 13 kg nitrogen and 150 g corrosive per 666 .7 m2 was suitable for the tested region .
