用稀土提高马尾松产脂量研究初报

本文采用低浓度稀土溶液处理割面,正交试验表明,经较优组合A_1B_2C_2(0.5%稀土溶液;施药时间8月;施药间隔期3天)处理的割面平均单刀产脂量比对照提高31.6%。

Preliminary Report of the Research on Increasing Resin-Producing Yield of Pinus massniana Using Rare Earth

In this article, the rare earth solution with low concentration isadopted to treat the tapping face and the orthogonal experiment reveals that theaverage resin-producing yield of the tapping face treated by the optimizing com-bination A_1B_2C_2 increases by 31.6 percent than that of the check tapping faceeach tapping time. The optimizing combination A_1B_2C_2 is that the rare earth so-lution is 0.5 percent, the drug is applied in August and the interval time of drugapplication is 3 days.
