摘要
对江西1991年冬季经济林冻害情况进行了调查,比较了各树种、品种的抗冻能力,并分析了地形地势、经营管理水平等因素对冻害的影响,依此指出了防冻措施。
Investigations were carried out in 1991 relating to frost bite occurring in nontimber product forest crops. By a comparison of the frost resistance capabilities shown by different species and varieties, it is concluded that the land form, the terrain, and management were the main factors which held responsibility for the frost bite. Accordingly, the protective approaches are put forward.
