2009～2010年玉米秸秆还田与氮肥配合施用对小麦产量性状的影响

[目的]为了研究玉米秸秆还田和配施最适宜的氮肥量.[方法]研究了6种肥料供应模式对小麦产量及生育性状的影响.[结果]在以安阳市生态条件为代表的豫北地区,如果仅从高产的角度考虑,6种模式中处理④、处理⑤、处理⑥都是较好的模式.[结论]100％玉米秸秆粉碎还田＋氮肥195 kg/hm2＋秸秆腐熟剂15kg/hm2,是取得小麦高产、高效的最佳模式.

Effect of Matching Use of Maize Straw and Chemical Fertilizer on Wheat Yield and Agronomic Characters in 2009-2010

[Objective] The research aimed to study the optimum nitrogen amount combined with maize straw.[Method] The effects of 6 kinds of fertilizer-supplying mode on the output and growing characters of the wheat were studied.[Result] Under the ecological condition of Anyang City as the representative of the north area of Henan Province,treatment ④,treatment ⑤ and treatment ⑥ were better among the 6 modes,only considering the high-yield of the wheat.[Conclusion] 100％ crushed maize straw returning to the field ＋ nitrogen fertilizer 195 kg/hm2 ＋ strawdecomposing 15 kg/hrn2 was the best mode.
