摘要
以高光效大豆品种黑农40为材料、设覆膜、未覆膜(CK)两个处理,在岗地和平地上研究了行间覆膜栽培技术增产效果及群体生理。结果表明:大豆行间覆膜栽培技术在适应推广区域内是一项具有显著增产效果和推广价值的栽培技术,展览田试验(平地)增产21%,东岗试验(岗地)增产25.4%;黑农40群体叶面积指数、光合势、净光合生产率、群体中单叶光合速率、根瘤数及根瘤鲜重、地上部生物产量和经济产量积累及分配,在黑农40不同生长发育时期东岗试验(岗地)和展览田试验(平地)均是行间覆膜栽培高于未覆膜栽培(对照)。这些结果揭示了大豆行间覆膜栽培技术增产的群体生理基础。
Effect of covering plastic film technique in furrow on yield and population soybean was studi ed,with high photosynthetic efficiency soybean cuhivar Heilong physiology in 40 as material. The results indicated this cultivation technique could increase soybean seed yield great the range of yield increment was 21%-25.4% The targets of photosynthetic physiolog more improved than that of CK, also including biological and economic yield. These showed the population physiology basis of covering plastic film in soybean furrow.
