| 摘 要： | 大豆连作减产早已为生产实践所证实。本文在对连作大豆减产规律调查研究的基础上,从大豆—土壤两个生态系统出发,对减产原因进行了分析,提出导致大豆连作障碍产生的原因是由土壤营养元素亏缺,物理、化学及生物活性改变,病虫害加剧等原因综合作用于大豆,使大豆生育受阻,产量下降。

| Abstract: | The yield reduction of continuous soybean cropping was been proved by the farmers,activity. In this study we analyzed the yield reduced reson froom soybean and soil two ecological systems. We concluded that the barrier caused by continuous soybean cropping was the comprehensive result of soil element deficiency, poor soil physical conditions and changed chemical and biological activities and occurred diseases. Such comprehensive factors hinder soybean growth,and results in yield reduction. |
