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。
The results showed that the photosynthetic rate of ginger was closely related to the yield of ginger, and the population photosynthesis rate was determined by the composition of the population. High-yielding population ginger branch number per unit area should be more than 150 / m2, leaf area index of not less than 6m2 / m2. In this study, three populations with density over 7000 plants / 666.67m2 met this requirement. There was no significant difference in plant height, branch number, leaf area index, photosynthetic rate and yield between the three populations Have access to high yield. The diurnal variation of photosynthetic rate of ginger population showed a typical unimodal curve but a bimodal curve different from that of single leaf photosynthesis.
