摘　　要：探讨了充脂处理对马尾松胸径生长的影响.经分析表明,充脂处理对马尾松胸径增加值有显著影响,每株充脂树每年胸径、材积分别少增加0.19cm和4.15×10-3m3.在马尾松间伐材进行充脂处理,没有发现虫害的发生.试验中有少量处理树木死亡,建议进行伐前充脂处理为妥.This paper studied the effect of chemical treating on the growth of DBH.The results showed that chemical treatments affected the growth of DBH of Pinus massoniana lamb significantly.Every treated tree had reduced its growth of DBH and timber volume by 0 19cm and 4 15×10 -3 m 3 respectively.During chemical treatments of Pinus massoniana stumpage, no pest broken out and only a few treated trees died.It was a safe treated before cutting.
