摘要
[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。
[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.
