| 摘 要： | 研究了九种作物的表观光合作用日变化,发现小麦、香蕉、椰子有严重型午睡,其午睡的生物产量损失依次为73.3%、38.8%、36.5%.谷子、马铃薯、水稻、橡胶有双峰型午睡,其午睡的生物产量损失依次为29.5%、30.2%、29.6%和51.0%.甘蔗和竹不表现午睡现象.认为克服午睡将会大幅度提高作物的产量.

| Abstract: | In the study on the net photosynthetic change at whole day of nine kinds of crop. It was found that the netphotosynthetic change at whole day of some crops such as wheat, coconut and banana appear as severe types middaynap,and its decrease of yield of biotic potential was 73.3%, 38.8% and 36.5% respectively. At other crops such as Italian millet, potato, rice and rubber tree ( Hevea brasiliensis) appear as bimodal types middaynap, and its decrease of biotic potential was 29.5%, 30.2%, 29.6% and 51.0% respectively. But the middaynap at the sugarcane and bamboo was not found.It was suggested that if the net photosynthetic middaynap was subdued, the yeild would be increasing notably. |
