【摘要】 通过对红星苹果单叶的光-光合作用特征的测定和分析,了解了其光合量随光强变化的规律;在调查苹果树冠内辐照度分布规律的基础上,提出了采用银色地膜覆盖增加苹果树冠内辐照度,改善树冠的受光条件,从而增加树冠的光合量,提高苹果的单果重和总产量.此外,还观察到银膜覆盖使果实的品质有较大的改善.更多还原

【Abstract】 Through the determination and analysis of single leaf photosynthesis condition of Sparkling Apple, the regulation of photosynthesis varied with the luminous intensity was understood. We investigated the distribution of irradiation within the canopy of apple trees and suggested both single fruit weight and yield could increase through the increase of photosynthetic activity by the use of silver-film to cover the soil surface which largely increased irradiation within the canopy and improved the light receiption of the canopy. In addition, the fruit quality was also improved by the use of this kind of technique.更多还原
