采用作物生长模拟方法，从光合有效辐射吸收、辐射利用效率和收获指数等方面比较了冬油菜和冬小麦的产量形成。冬油菜从4月15日至成熟期的累积入射PAR、累积吸收PAR、辐射利用效率和收获指数均低于冬小麦。为了提高冬油菜的潜在产量，应选择光合有效辐射累积吸收量、光能利用率和收获指数较高的作物类型。(C)1997年Elsevier Science B.V.
Yield formation of winter oilseed rape was compared with that of winter wheat in terms of absorption of PAR, radiation use efficiency and harvest index by means of crop growth simulation. Cumulative incoming PAR from April 15 until maturity, cumulative absorption of PAR, radiation use efficiency and harvest index were lower for winter oilseed rape compared with winter wheat. To improve potential seed yield of winter oilseed rape, a crop type with increased cumulative absorption of PAR, radiation use efficiency and harvest index is desirable. (C) 1997 Elsevier Science B.V.
