漆树营养液对漆树生长与生漆产量的影响

Toxicodendron verniciflum(Stokes) F.A.Barkley Nutrient Solution Effects on its Growth and Lacquer Production

为寻求生漆增产措施,笔者用专门配制的含磷、钾、硼、铜、镁等矿质元素和生长调节物质的"漆树营养液"对毛坝漆树进行喷施处理,观察处理组与对照组漆树生长发育情况并测定其平均单株产漆量。试验结果表明:①处理组较对照组漆树生长茂盛,树皮增厚,漆树落叶时间延长半个月左右;②"漆树营养液"对漆树的生长发育无毒副作用;③"漆树营养液"处理后的漆树的生漆产量平均增产达21.2%。增产机理是:施用"漆树营养液"后的漆树的代谢合成能力增强了。

In order to increase the production of the raw lacquer,the authors prepared the Toxicodendron verniciflum（Stokes） F.A.Barkley nutrient solution with mineral elements（P,K,Cu,Mg,etc.） and plant growth regulators,sprayed it on the Maoba lacquer tree were used to study.The result showed that the its flourish,bark thickening,the time of leaf shed were postponed about half a month,no side effect in the treat group.The raw lacquer production was increased 21.2% in the treat group.Production mechanism is that the lacquer enhances the metabolic synthesis after using nutrient solution.
