摘　　要：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．The physiological indexes of summer soybean variety Youchu 4 for a yield of 4554.23kg/ha were studied. The variety had its total dry matter 15 579.44kg, economic coefficient 29.2%, leaf area coefficient 0.33 at branching, 1.62 at flowering, 6.15 at podding and 5.19 at seed filling, total photosynthetic potential 2 757 174.20m 2. d (the value from podding to maturing accounted for 65.1% of total), average net photosynthetic rate 5.65g·m -2 ·d -1 (The highest one was up to 9.53g·m -2 ·d -1 at podding and seed filling stage) , total N accumulation 422.658kg and total P accumulation 53.751kg ( 9.281kg of N and 1.180kg of P were absorbed for the production of 100kg seeds and related straws on average).
