摘要
通过对扁桃主干分层形、开心形和自然生长树形(对照)的光合特性(2006、2007年)、叶绿素含量(2006年)及产量(2007年)的比较研究,结果表明:扁桃修剪后明显增强了树体的光合作用,提高了叶片内叶绿素的含量,增加了产量。其中主干分层形的增幅最大,两年平均净光合速率、蒸腾速率和水分利用效率值分别增加了23.0%、56.0%和19.6%,平均株产和单产分别达到了4.1和136.3 kg/667 m2,增幅达57.7%和60.7%,是新疆扁桃丰产的理想树形。
The comparative research on photosynthetic characteristics （2006, 2007）, chlorophyll content, （2006）, and the amount of output of almond trunk delaminating figure, splay figure and natural figure （comparison） was carried out. The research results demonstrated that the tree figue photosynthesis was greatly improved. After pruming almond tree, chlorophyll content and its output were increased： Among all figures of almond trees, trunk delaminating figure has the best effect. During these two years, the average net photosynthetic rate of it has increased by 23.0%, the transpiration rate has increased by 56.0%, and WUE has increased by 19.6%. The swains yield reached 4.1 kg and the per - mu yield reached 136.3 kg. The increasing rates are 57.7% and 60.7 %. From these data, it can be proved that trunk delaminating figure is the ideal tree - figure for high yield of Xinjiang almond.
