摘要
79645大豆是高度自我调节的群体。在西宁地区生态条件下,其适宜种植密度范围较大。不同种植密度差异为1.81～4.25万株/667m^2,但密度不同,大豆植株经济性状也不同。本试验结果表明:79645大豆每亩种植密度以1.81～2.88万株的群体结构较为适宜,平均产量达112.8kg/667m^2。
Soybean 79645 (Glycine max Merr) was a highly self- adjusting colony under the ecological conditions in Xining. This soybean had a good adaptability of sowing density, which varied from 18100 to 42500 plants/667m2, and its economic characters differed as well. The experimental results showed that soybean 79645 the densities from 18100 to 28800 plants/667m2 are suitable. Arerage yield reached 112.8kg/667m2
