摘要
[目的]研究玉米秸秆还田和施氮方式对小麦产量及其构成的影响.[方法]在玉米秸秆还田的情况下,采用随机区组设计,连续4a定点试验,研究在豫北潮褐土类小麦田,施氮方式及添加秸秆腐熟剂对小麦产量、群体、穗粒数、千粒重的影响,寻求最佳施氮方式.[结果]豫北潮褐土类小麦田,在施氮225 kg/hm2水平下,以氮肥基追比5∶5 +2 250 g/hm2秸秆腐熟剂的施肥方式小麦产量和千粒重最高.[结论]氮肥基追比5∶5+2 250 g/hm2秸秆腐熟剂为最佳小麦施肥方式.
Abstract
[Objective] The aim was to study effects of corn straw returning to field and N application way on wheat yield and components.[Method] Under the situation of corn straw returning to field,using random block design,fixed site experiment was conducted for 4 consecutive years,effects of N application way and adding straw decomposition agent on yield,group,grain number per spike,1 000-grain weight were studied to obtain the optimal N application method.[Result] In wheat field with moisture and brown soil in northern Henan Province,wheat yield and 1 000-grain weight was highest under the condition of applying N 225 kg/hm2 and adding 5 ∶ 5 + 2 250 g/hm2 straw decomposition agent.[Conclusion] With N as base fertilizer topdressing 5∶5 +2 250 g/hm2 straw decomposition agent is the optimum fertilizer application way.
