摘　　要：通过连续8年在全省5个生态区9个9区固定轮作场圃综合试验,试验区专项研究,区、盆栽试验,实验室分析,以及大量的大面积生产调查,发现大豆重、迎茬种植,生育期延迟,植株变矮、细弱、结荚减少,生长发育进程前期减缓、后期加快,干物质积累减少。The experiments had been carried out by 8 years in 9 rotation nurses with 9 plots and series of field experiments in 5 ecological regions of Heilongjiang Province since 1993. In the same time, the investigation was made in soybean fields. The result showed that:when the soybean was cultured continuously and alternately, its plant was shorter than that in normal rotation. And its stem became some thinner, and producing pods decreased. Also, the progress of growing and developing was delayed in the prophase,quickened in the anaphase. Growing period became some longer, but the amount of dry matter accumulated was reduced.
