基于改接皂荚的野皂荚林改造模式研究

摘要

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 .%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。
