摘要
Abstract
Objective] The aim was to investigate the tree-crown structure characteristic of Shixia longan airtight orchard.[Method] The in-vestigation of the tree-crown structure of Shixia longan airtight orchard was done, and the basic characteristics of canopy structure and related parameters was obtaind.[Result] The study showed that the plant and row space was 4.36 m ×5.62 m, tree height was 3.50-5.40 m and average was 4.76 m, tree-crown height was 3.14 m, vertical crown breadth was 6.82 m, lateral crown breadth was 6.03 m, the average of vertical cross length was 2.46 m, the average of lateral cross length was 0.41 m.The tree-crown of one single plant was round and the plants in the same line connecting into an integrative body which make the “hedgerow” structure.There was one main trunk and the average perime-ter of it above 10cm to the ground was 72.4 cm, it also had 2 to 4 main branch and its perimeter was 65.4 cm.The average of branching de-gree was 13.2, the volume of leaf layer was 15.77 m3 and the bare chamber was 7.84 m3 , the relative intensity in chamber was 12.7% and the relative intensity between plants was 18.6%.The canopy coverage rate was 73.96%, leaf horizontal density in the garden was 13.31, leaf area index was 11.60, the rate of tree-crown was 48.87% and the production volume coefficient was 66.79%.[ Conclusion] The research provide the reference for crown shaping and enclosed modification of of Shixia longan airtight orchard.关键词
