| 摘 要： | 研究了大豆连作条件下植株体内营养水平和叶绿素含量、光合速率及其产物的差异。结果表明 ,由于连作造成根际土壤障碍和植株生长发育障碍 ,导致体内硝态N、速效P、速效K含量显著降低 ,使叶片叶绿素含量、光合速率、体内可溶性糖、氨基酸总量极显著下降 ,影响大豆叶片的光合性能和有机物的积累 ,从而导致减产。随着连作年代的延长呈现渐低趋势 ,表现为正茬 >迎茬 >重茬。

| Abstract: | Study on the effect of successive planting soybean to nutrient, Chlorophyll, Photosynthetic efficiency and photosynthetes was conducted. The result showed that continuous cropping soybean affected soil condition and soybean plant developing which resulted to the NO 3-N, avilable P, avilable K chlorophyll. Photosynthetic efficiency, soluble sugar and arnimo acids decreasing So that the photosynthetic effioiency and organic matter accumultaion were affected, which resulted to soybean grain yield decreasing, with the years of successive planting soybean in creasing, the tread of grain yield decreasing was more obvious. The result also showed that planting soybean every oter two years was better than that every other one year, however which was better than that successive planting soybean. |
