利用面积为 1 4.33hm2 的固定试验区 ,定位研究不同采集作业方式对马尾松次生阔叶混交林天然更新效果的影响 .结果表明 :主伐强度不同 ,对马尾松次生林更新密度、更新频度和1年生幼苗各器官生长量都有显著影响 ;集材有利于种子的着床发芽 ,对更新密度有显著影响 ,但对更新频度和幼苗生长无明显影响
The effects of different harvesting practices on the natural regeneration of Pinus massoniana secondary broad-leaved mixed forest were studied by using a fixed experimental area of 1.43hm2 and the results showed that there was no significant difference in the regeneration density, renewal frequency, The growth of organs of 1-year-old seedlings all had significant effects on the growth of seedlings. Skidding was beneficial to the seed germination and seed germination, which had a significant effect on the regeneration density but had no significant effect on the frequency of renewal and seedling growth
