研究了商豆6号3 784.5kg·hm-2产量的群体生育动态及生理指标。结果表明,在密度181 350～191 850株.hm-2、单株成荚65.4～72.3个、单株粒数137.3～145.2个、百粒重16.6～17.2 g条件下,均能实现3 800kg.hm-2的产量;开花至结荚期是植株生长最快的时期,株高日增长2.12 cm;结荚期叶面积指数达最大值(5.72),叶面积变化动态属稳升稳降型;全生育期总光合势2 636 831.83 m2.d,平均净光合生产率4.70 g.m-2.d-1,干物质积累12 393.56kg·hm-2,粒茎比0.52,经济系数0.31。
The population dynamics and physiological indices of 3 784.5kg · hm-2 production in Shangdan 6 were studied. The results showed that under the condition of density of 181 350-1 191 850 hm-2, 65.4-72.3 pods per plant, 137.3-145.2 pcs per plant, and 16.6-17.2 g per hundred weight, 3 800 kg could be achieved. hm-2. The flowering stage to the podding stage was the fastest growing stage with the plant height increasing by 2.12 cm. The leaf area index reached the maximum during the podding stage (5.72) The total photosynthetic potential during the whole growth period was 2 636 831.83 m2.d, the average net photosynthetic production rate was 4.70 gm-2.d-1, dry matter accumulation was 12 393.56 kg · hm-2, grain-stem ratio was 0.52, and economic coefficient was 0.31.
