摘要:

以硝酸稀土为主要成分并添加微量元素的化学增脂剂与生物增脂剂乙烯利、α-萘乙酸复合施用于思茅松,并进行增脂研究,结果表明,复合施加化学增脂剂和生物增脂剂乙烯利的思茅松年均增脂率可达29.7%。通过对施用增脂剂的思茅松进行生理指标测试表明:施用增脂剂后,促进松树的光合作用,松针干质量和叶绿素质量分数分别提高了11.2%和5.6%,促进可溶性糖转化为松脂。思茅松的三大保护酶超氧化物歧化酶(SOD)、过氧化物酶(POD)、过氧化氢酶(CAT)活性可分别提高108.6%、87.3%和104.8%,增加了思茅松环境适应能力和抗逆性,从而提高松树产脂能力。

Abstract:

Chemical tapping irritant agent which consisted of rare earth nitrate containing trace elements and biological tapping irritant agents(ethephon and α-naphthylacetic acid) were used in the tapping of P. kesiya, and the mean annual rate of increasing resin after tapping chemical tapping irritant and ethephon could reach 29.7%. The physiological indexes of P. kesiya treated with tapping irritant agent were tested. The results showed that after application of tapping irritant agent, the photosynthesis of pine was promoted, the dry weight of pine needles and the content of chlorophyll were increased by 11.2% and 5.6% respectively, and the transformation of soluble sugar into resin was promoted. The contents of superoxide dismutase(SOD), peroxidase(POD) and catalaes(CAT) in leaves of P. kesiya increased by 108.6%, 87.3% and 104.8%, respectively. Thus, the adaptability and resistance of P. kesiya to environment were improved, and the ability of resin production was improved.

Key words: Pinus kesiya Royle ex Gordon, tapping irritant agent, peroxidase, superoxide dismutase, increasing resin effect
