| 摘 要： | 采用LI-6400便携式光合仪对室外3种不同密度的菠萝光合作用特性进行了研究。结果表明:3种不同密度菠萝的净CO2吸收速率日变化曲线基本一致,都呈现下行抛物线,早上与傍晚较高,下午15:30前后基本为0;其中密度4.6株/m2的净CO2吸收速率更显著(α=0.1)。此外,密度3的叶面有效光、温度、水分含量等生态因子也比另外两种密度(3.8株/m2、4.4株/m2)更有利于光合作用。

| Abstract: | The photosynthesis of the pineapple in different planting density was investigated with LI-6400 portable photosynthesis system.The daily patterns of net photosynthetic rate of different density pineapple appeared as down parabola,which was higher in morning and dusk,zero at about 15:30.The net photosynthetic rate of the third density,4.6 individual-plants per square meter,was more significant than the other two.And the efficiency light,temperature and the content of H2O in air of the leaves' surface in the third density were more favorable for the photosynthesis. |
