| 摘 要： | 为探讨油松被松毛虫危害后的补偿机制，该文以与植物最基本生命活动密切相关的光合反应为研究对象，分析和比较了失叶对光合作用及部分光合条件的影响．结果表明：油松针叶适度受害后，在材积和营养物质储存方面所表现出的补偿和超补偿现象，最初是以光合产物总量增加为基础的，因此补偿具有广泛性；光合强度提高的客观条件是与光合作用直接相关的光、水向有利于提高光合强度的方向发生了转变，其中水分状况的改善有着重要意义

| Abstract: | Based on the field experiment and the analysis of the information,the effects of defoliation caused by artificial method or damaged by pine caterpillar on the photosynthesis and its conditions of Chinese pine have been studied.The results indicate that the compensation of Chinese pine with certain defoliation rate is widespread. Under certain defoliaton rate,light and water, which is directly related with photosynthesis,have favourably changed to improve photosynthesis.Water situation is a critical factor in photosynthesis improvement process. |
