摘要: 以湖北省钟祥市主栽小麦品种郑麦9023为供试材料,设置常规施肥(CK)、减施20%化肥+有机肥+增效剂(M1)、减施20%化肥(M2)3个处理,研究不同化肥减施模式对稻茬小麦抗倒性能与产量的影响。结果表明,与CK相比,M1、M2处理的小麦每穗粒数、理论产量、千粒重、基部第2、3节茎秆厚度均显著增加;M1、M2处理的小麦基部第2、3节机械强度随着茎秆厚度的增加而加强;M1、M2处理的实际产量增幅分别为51.24%、66.62%,理论产量增幅分别为42.70%、43.30%。结果表明,M1、M2处理均可作为湖北江汉平原小麦的抗倒、丰产与稳产的施肥模式。为江汉平原稻茬小麦化肥减施增效技术的应用推广提供理论依据。

Abstract: This paper used Zhengmai 9023, the main wheat variety planted in Zhongxiang city, Hubei Province,as the test material, three treatments were set up, which were conventional fertilization control(CK), 20% chemical fertilizer reduction + organic fertilizer + synergist (M1) and 20% chemical fertilizer reduction (M2). The effects of different chemical fertilizer reduction patterns on lodging resistance and yield of wheat after rice were studied. The results showed that compared with CK, the number of grains per panicle, theoretical yield, thousand-grain weight and basal node 2 and 3 stem thickness of wheat treated with M1 and M2 increased significantly.The mechanical strength of the second and third basal nodes treated with M1 and M2 enhanced with the increase of the stem thickness; the actual yield of M1 and M2 increased by 51.24% and 66.62% respectively, and the theoretical yield increased by 42.70% and 43.30%, respectively. The results showed that M1 and M2 treatments could be used as fertilization models for lodging resistance, high yield and stable yield of wheat in Jianghan Plain, Hubei Province. This paper provided a theoretical basis for the application and promotion of fertilizer reduction and efficiency enhancement techniques for wheat after rice in Jianghan Plain.

Key words: wheat, fertilizer reduction, lodging resistance, yield
