| 摘 要： | 为探索北疆麦茬夏大豆早熟稳产高效的复种方式,通过田间试验,研究了6月23日套种（B1）、6月27日套种（B2）、免耕7月2日播种（B3）、翻耕后7月6日播种（B4）4种复种方式对黑河45号干物质积累、产量及经济效益的影响。结果表明,与B4处理相比,B1、B2、B3生育进程提前,成熟期提前9~19d,生育期缩短2~4d。B1、B2、B3的叶面积指数增长和干物质积累提前,干物质积累量降低。B1增产显著,B2、B3产量差异不显著;B1需人工播种,生产上难于大面积应用。B3提前9d成熟,因节省了耕地费,增收440.72元/hm 2。在本试验条件下,抢收冬麦、免耕播种是伊犁河谷麦茬夏大豆的早熟稳产高效种植方式。

| Abstract: | In order to explore the ripening early, yield stable and economical efficient multiple cropping patterns for summer soybean, four kinds of multiple cropping methods that interplanting on June 23rd (B1), interplanting on June 27th (B2), no tillage on July 2nd (B3), and sowing on July 6th after plowing (B4) were used to study the dry matter accumulation, yield and economic benefit of Heihe 45. The results showed that compared with B4 treatment, the growth and development process of B1, B2 and B3 was advanced. The mature stage was advanced 9-19d, Growth period has been shorten 2-4d, Leaf area index increased and dry matter accumulation was ahead of time but dry matter accumulation amount decreased for B1, B2 and B3. B1 had a significant yield increase, however there was no significant difference in yield between B2 and B3. Since B1 needed artificial seeding, so it was difficult to apply in large area in production. B3 increased income 440.72 yuan/hm 2 because of saving the cost of cultivated land, and ripened earlier for 9d. Under the condition of this experiment, harvesting winter wheat quickly with no tillage to planting was the ripening early, yield stable and economical efficient multiple cropping patterns for summer soybean under wheat-stubble in Yili Valley. |
