| 摘 要： | 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N13 kg+精制鸡粪100 kg和施纯N13 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。

| Abstract: | 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 returning 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 consistent 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 666.7m2 was suitable for the tested region. |
