基于改接皂荚的野皂荚林改造模式研究

Study on Gleditsia microphylla Forest Transformation Mode Based on Grafting Gleditsia sinensis

皂荚是一种典型的生态经济型树种,其经济价值显著高于野皂荚。笔者通过分析3种野皂荚灌木林割灌整地模式对皂荚嫁接苗的苗高、基部粗度的影响,计算3种模式的投入成本,确定最优割灌整地模式和最佳割灌时间。结果表明,带状割灌整地为野皂荚灌木林地改造最优模式,当年的11月份至次年清明前为最佳割灌时间。

Gleditsia sinensis was a typical economic and ecological tree, and its economic value was higher than that of Gleditsia microphylla. Though the analysis of influence of transformation mode on seedling height, basal width in three Gleditsia microphylla forest and invested cost of 3 transformation mode, the anthor would determine the best cutting shurb mode and time. The results showed that the zonal cutting shrub transformation was the optimal transformation mode, and the best time of cutting shrub was between December and Qingming in the next year.
