摘要
【目的】研究不同耕作方式对夏大豆生长发育、产量及土壤水分动态变化的影响,为当地夏大豆种植选择适宜的耕作方式提供一定的理论依据。【方法】2013年于伊宁县进行翻耕(T)、翻耕覆膜(TP)、免耕(NT)三种不同耕作方式的田间试验。【结果】与翻耕和免耕相比,翻耕覆膜能有效促进夏大豆的生长发育,形成良好的农艺性状和群体结构,产量分别比翻耕和免耕提高7.43%和16.05%;同时翻耕覆膜处理能够显著提高苗期和成熟期0-60 cm的土壤平均含水量,分别比翻耕提高了25%、16%,比免耕提高38%、16%;其水分利用效率也分别比翻耕和免耕提高16.03%和7.84%。【结论】在伊犁河谷夏大豆种植中,翻耕覆膜能够促进植株的生长发育,保持较高的土壤含水量从而提高夏大豆的产量。
[Objective ] To study the effects of different tillage methods on summer soybean growth, yield and soil moisture dynamics of growth, the appropriate choice for the local summer soybean farming methods provide a theoretical basis. [ Method] The field trail was conducted by 3 different tillage : setting tillage ( T), plowing film (TP), no-tillage(NT) in 2013 Yining County. [ Result] Compared with the conventional till- age and the no -tillage, tillage film could effectively promote the growth of summer soybean, form a good ag- ronomic traits and population structure. Yields were increased by 7.43% and 16.05% compared with tillage and no- till. Meanwhile, plowing coating process significantly improved the average soil moisture content at the depth of 0 -60cm during seedling and mature periods by 25% and 16%, and compared with no -tillage, the increased rate was 38% and 16% ; Their water use efficiency was also increased by 16.03% and 7.84% than T and NT. [ Conclusion ] In summer soybean planting in Yili River Valley, tilling film could promote the growth of plants and maintain high soil moisture, thus improving summer soybean yield.
