| 摘 要： | 研究结果表明，姜群体光合速率与群体姜产量密切相关，群体光合速率决定于群体的构成。高产群体姜的单位面积分枝数应超过１５０／ｍ２，叶面积指数不得低于６ｍ２／ｍ２。本试验中种植密度超过７０００株／６６６．６７ｍ２的３个群体均达到了这一要求，这３个群体间的株高、分枝数、叶面积指数、群体光合速率和产量均无显著差异且都获得高产。姜群体光合速率的日变化呈典型的单峰曲线而异于单叶光合的双峰曲线。

| Abstract: | Canopy photosynthesis was closely related to yield in ginger (Zingiber officinale Roscoe). Furthermore, it depended on the canopy constitute. The unit area branches and LAI were over 150/m2 and 6m2/m2 respectively in the higher yield canopy of the crop. The three canopies over 7000 plants/666. 67m2 satisfied the two demands.Height, branches, LAI, canopy photosynthesis and yield had no remarked differnce among the three canopies and all the three canopies obtained higher yield. Diurnal change of the canopy photosynthetic rate showed a typical single peak curve which was different from the double-peak curve from that of single leaf photosynthetic rate. |
