丰脂灵化学采脂对马尾松木材构造及其松脂产量的影响

用丰脂灵化学采脂和常规采脂对广西派阳山林场的马尾松进行采脂试验，并取样测定木材树脂道的数量、大小与分布及木材明子化程度。结果表明，丰脂灵化学采脂更有利于马尾松木材树脂道的形成，其轴向树脂道数量比常规采脂的高３１．５％，比尚未采脂的高５７．２％。丰脂灵化学采脂对马尾松木材树脂道直径的影响作用不明显。丰脂灵化学采脂的木材明子化程度比常规采脂的低６１．６％。丰脂灵化学采脂的松脂产量比常规采脂的高３９．３４％，其产出与投入的比值为３．９３。表明丰脂灵是值得推广的一种营养型松脂增产促进剂。

Effect of Collecting Resin with Rich-resin Panacea on Wood Structure and Resin Output of Pinus massoniana

The methods of collecting resin with Rich-resin panacea(RRP) and without RRP(normal way) were used in the resin collecting experiment of Pinus massoniana Lamb,in Paiyangshan forest farm,Guangxi.The quantities, diameter and distribution of wood resin canal and the degree of resined wood were determined.RRP method was more beneficial to the formation of wood resin canal.The quantities of longitudinal resin canal was 31.5% higher compared with the normal way,and 57.2% higher compared with the un-collecting resin. The effect of RRP method upon diameter of wood resin canal was not obvious.Compared with the normal way,degree of resined wood by RRP method was 61.1% lower, and resin output from RRP method was 39.34% higher.The input-output rate was 3.93.It suggests that RRP is a stimulate agent of nutrition-type,and is worth popularing in pine tree resin collecing.
