| 摘 要： | 本实验对西瓜三个品种“新澄”、“郑杂五号”、“金花宝”等的光合强度和“新澄”不同密度的叶面积指数进行了测定,结果表明:“新澄”的光合强度最大,干物质为12.23mg/dm~2·h,“郑杂五号”和“金花宝”次之,分别为7.70mg/dm~2·h和7.48mg/dm~2·h。“新澄”的产量在叶面积指数1.01—1.41范围内,随着叶面积指数的增加而提高,当叶面积指数超过1.41以后,产量有下降的趋势。西瓜品种“新澄”合理的叶面积指数为1.4左右。

| Abstract: | The photosynthetic intensity of Citrllus vulgaris cvs. Xin CHeng, Zheng Za 5 and Jin Hua Bao and leaf area indices of cv. Xin Cheng in several planting densities were studied. The results showed that the photosynthetic intensity of cv. Xin Cheng was the highest and it was 12.23mg dry matter/dm ·h. The ones of cv. ZHeng Za 5 and Jin Hua Bao were less and they were 7.70and 7.48mg dry matter/dm·h. respectively. The yield of cv. Xin Cheng increased with an increase in leaf area indices from 1.01—1.41. However, when leaf area indices is higher than 1.41, and the yield showed a decreased trend. The proper leaf area indices of cv. Xin Cheng was about 1.4. |
