通过研究提出了夏大豆诱处４号公顷产４５５４．２３ｋｇ的各项生理指标：总干物质积累１５５７９．４４ｋｇ，经济系数２９．２％；叶面积系数在分枝、开花、结荚、鼓粒期分别为０．３３、１．６２、６．１５、５．１９；总光合势２７５７１７４．２ｍ２·ｄ，其中结荚期至成熟期占总光合势的６５．１％；平均净光合生产率为５．６５ｇ·ｍ－２·ｄ－１，结荚至鼓粒期为最高，达９．５３ｇ·ｍ－２·ｄ－１；氮、磷的总积累量分别为４２２．６５８ｋｇ和５３．７５１ｋｇ，平均每生产１００ｋｇ籽粒和相应秸秆需吸收氮９．２８１ｋｇ、磷１．１８０ｋｇ
Through the research, we put forward the physiological index of 4554.23kg for No. 4 hectare induced by summer soybean: the total dry matter accumulates 15579.44kg, the economic coefficient is 29.2%; the leaf area coefficient is in the branch, flowering, pod, The total photosynthetic potential was 2757174.2m2 · d, in which pod stage to maturity accounted for 65.1% of the total photosynthetic potential; the average net photosynthetic productivity was 5.65g · m-2 · d-1, and the maximum podding to druming period was 9.53g · m-2 · d-1. The total nitrogen and phosphorus accumulation were 422.658kg and 53.751kg , The average production of 100kg grain and the corresponding straw need to absorb nitrogen 9.281kg, phosphorus 1.180kg
