摘要
[目的]为菏泽地区冬小麦的合理施肥提供理论依据。[方法]在冬小麦-玉米连作中,以济麦21为试材,以不施肥为对照,设定了6个NPK化肥和有机肥料配施处理,有机肥料作为基肥在冬小麦播种前使用,化肥在夏玉米生长期间施用。收获时测定生育性状和各重复的实际产量。[结果]施肥处理可显著提高冬小麦株高、穗长和穗粒数,也提高了冬小麦千粒重。与对照相比,施肥处理显著提高冬小麦生物产量,依次为NPK+高量有机肥>NPK+常量有机肥>NPK+高量麦秸还田>NPK+玉米秸还田>NPK+常量麦秸还田>NPK>CK。施肥处理对冬小麦的产量提高也表现出同样的趋势。[结论]配施有机物料比单施NPK化肥效果好,配施高量有机肥比配施常量有机肥效果好。
[ Objective] The objective of the study was to provide the theoretical base for rational fertilization in winter wheat in Heze. [ Method] In winter wheat-malze continuous cropping, with Jimai21 as tested material and no fertilizer as CK, 6 treatments of NPK fertilizers mixed with organic fertilizers were set up, the organic fertilizer was used as base-fertilizers before winter wheat seeding and the chemical fertilizers was used during maize growth period. The growth characters and actual yield of winter wheat were measured in harvest. [Result] Treated with fertilizers, plant height, spike length and kernel per spike as weU as 1 000-kernel weights of winter wheat could be significantly improved. Comparing with CK, the biological yield of winter wheat treated with fertilizer could be significantly improved, and in decreasing order was NPK ＋ high rate of organic fertilizer 〉 NPK ＋ normal rate of organic fertilizer 〉 NPK ＋ high rate of returning wheat residues 〉 NPK ＋ returning maize residue 〉 NPK ＋ normal rate of wheat residue 〉 NPK 〉 CK. Fertilization treatment showed same trend on the yield of winter wheat. [ Conclusion ] The effect of mixed application of NPK-organic fertilizers was better than that of NPK fertilizer alone, while the effect of mixed application of high rate of organic fertilizers was better than that of normal rate of organic fertilizers.
