摘要
通过对不同修剪处理的沙田柚密闭树的株间、内膛共2个点的离地面0、50、100、150和200cm五个高度分别测定光照强度,分析光照强度差异、叶片的重量、厚度、养分和果实质量,初步认为A、B两种修剪方法可极大地改善沙田柚的光照条件进而促进内膛春梢的萌发,增加叶片重量和厚度并在一定程度上改善果实品质,其中处理A的内膛效果较好,而处理B的株间效果较好。
After pruning the thick trees of Shatian Pomelo in different methods, the intensity of illumination in internal space of plant and in space between plants have been surveyed. The survey height is 0,50,100,150 and 200cm from ground. Through analyzing the difference of illumination intensity, weight, thickness and nutrition of leaves and quality of fruit, it was showed that illumination condition and internal spring shoots sprout had been improved obviously. The weight and thickness of leaves were increased and the fruit quality could be improved in a certain degree with A and B pruning methods. Treatment A had a better effect on internal space of plant, while Treatment B on space between plants.
