松树增脂剂应用效果分析

松树增脂剂在福建省马尾松主产区推广应用结果表明:施用增脂剂具有明显的增产效果,增产幅度达13 3%～36 1%,增脂剂对于低产马尾松树脂增产效果更为明显。增脂剂增产后效作用明显,施用增脂剂后,全年可增加30d采脂时间,并可延长采割年限2～3a,节约和保护采脂资源,提高采脂效率。

Application Effect on Reagent for More Resin of Pine

Reagents for more resin of pine were popularized and applied in main production region of Pinus massoniana in Fujian province.The results showed that reagents for more resin had a significant effect and back one on increasing resin yield for Pinus massoniana,reaching the rate of growth of 13.3%～36.1%,especially for the Pinus massoniana trees with original low yield.Pinus massoniana trees can be prolonged 30 days for collecting resin in the whole year and be prolonged 2～3 collecting years when applied reagents for more resin of pine,which saves and protects resource for collecting resin while raising efficiency in collecting resin.
