红黄壤区“豌豆-稻-稻”高产高效种植制度研究

 通过在红黄壤区稻田5年的研究(1995~1999年)，从品种引进筛选、适播期、适播量3个方面研究了稻田冬种豌豆的高产高效栽培配套技术。由“豌豆 稻 稻”的豌豆、早稻、晚稻品种筛选得出豌豆、早稻、晚稻3季品种优化搭配方式。通过“豌豆-稻-稻”3年连作试验，得出豌豆因连作而病害日益严重，产量逐年下降的结论，并对其低产原因进行了初步讨论，提出了“豌豆-稻-稻”与“大麦-稻-稻”3年1轮作的持续高产增收实用技术。

High-Yielding and Efficiency Cropping System Pea-Rice-Rice in Red-Yellow Soil Area

For increasing the economic income in red yellow soil area, pea rice rice cropping system were studied in Yiwu city, Zhejiang Province in 1995-1999. Varieties collocation mode of pea, early rice, late rice was selected. After three years of pea rice rice continuous cropping, the yield of pea was descent, the demage of diseases and insect pests of pea became serious. One year pea rice rice and two year barley rice rice rotation pattern sequent in three years was the measure for high yielding and efficiency.
