- 摘要:
- 在新疆阿克苏地区，以核桃树、枣树、苹果树、梨树为试验材料，利用HemiView数字植物冠层分析仪器，对新疆阿克苏温宿县试验基地内沟灌条件下的5年生果树进行冠层参数比较，分析计算不同种类果树的冠层参数，研究不同种类果树冠层参数之间的差异。结果表明：在沟灌条件下，不同种类果树叶面积指数的排列顺序为核桃树＞枣树＞苹果树＞梨树；透光率的排列顺序为梨树＞苹果树＞枣树＞核桃树；平均叶倾角的排列顺序为核桃树＞枣树＞苹果树＞梨树；截获辐射能的排列顺序为核桃树＞枣树＞苹果树＞梨树。在相同条件下，核桃树叶面积指数与透光率呈极显著负相关；枣树、苹果树、梨树的叶面积指数与透光率呈负相关关系、与截获辐射能呈正相关关系，而透光率与截获辐射能呈负相关关系。
- Abstract:
- In order to compare the canopy parameters on different kinds of fruit trees,the experiment which was taking walnut trees,jujube trees,apple trees and pear trees as experimental materials by using the HemiView canopy image analysis instrument was carried out at Aksu region in Xinjiang.The results showed that under the condition of furrow irrigation among these different friut trees,the order of leaf area index was walnut tree＞jujube tree>apple tree>pear tree;the order of light transmittance was pear tree>apple tree>jujube tree>walnut tree;the order of mean leaf inclination angle was walnut tree＞jujube tree>apple tree>pear tree;the order of radiant energy interception was walnut tree＞jujube tree>apple tree>pear tree.In the same situation,leaf area index of walunt trees was significantly negative correlation with light transmittance.For the rest of the three kinds of fruit trees,this conclusion applied to them,too.Besides,leaf area index had a positive correlation with radiant energy interception.Light transmittance showed a negative correlation with radiant energy interception.
