本文研究了翻耕、免耕不同条件下夏大豆的生育进程及对产量的影响。结果表明:在同期播种条件下,翻耕不仅能提高单株有效荚数和百粒重,比免耕平均增产5.55%,而且能缩短夏大豆的生育期。
The paper studied the growth and yield of summer soybean under different tillage and no tillage conditions. The results showed that tillage not only increased the effective pods and hundred kernel weight per plant, but also increased the yield by 5.55% compared with no-tillage, and shortened the growth period of summer soybean.
