松树增脂剂应用效果分析

Application Effect on Reagent for More Resin of Pine

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。

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.
