| 摘 要： | 目的]探讨江淮地区在紫云英-早稻-晚稻轮作制条件下紫云英与无机肥料的合理配比及施肥效应。方法]以早稻品种早籼7038和晚稻品种武运粳7号为试材,研究了江淮地区肥-稻-稻轮作制下,化肥与紫云英配施对水稻产量及其构成因素的影响。结果]早稻试验中,化肥施用量减少30%时,早稻产量随紫云英配施量的提高而明显增加,配施22 500 kg/hm~2紫云英处理的早稻增产效果最佳,比用100%化学肥料处理的高8.2%;晚稻试验中,晚稻产量随着前茬紫云英施用量的增加而增加,以前茬配施30000 kg/hm~2紫云英处理的产量最高,且略高于完全化肥处理。结论]增施化肥或配施紫云英致使水稻产量构成参数均有相应提高;前茬配施高量的紫云英对促进晚稻产量的效果最佳。

| Abstract: | Objective]The study aimed to discuss the rational ratio of Chinese vetch and inorganic fertilizer and their application effect. Method]With the early rice variety Zaoian 7038 and late rice variety WUyunjing 7 as the test materials,the effects of mixed application of Chinese vetch and chemical fertilizer on the rice yield and its yield components were studied.Result]In the early rice test,when the application rate of chemical fertilizer was decreased by 30%,the yield of early rice was increased with the r... |
