漆树营养液对漆树生长及生漆质量的影响

以提高生漆的质量为目标,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,观察漆树的生长情况并检测生漆质量.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,且无毒副作用;②处理组较对照组漆树所产生漆的漆酚、漆酶、树胶质等主要化学成分的含量增加;③处理组较对照组漆树所产生漆的感官检验指标明显改善;④处理组较对照组漆树所产生漆的表干时间缩短.其机理是施用"漆树营养液"后漆树的营养条件改善了,生漆的代谢合成能力增强了.施用"漆树营养液"可促进漆树生长并提高生漆质量.

Effects of Lacquer-tree Nutrient Solution on Lacquer-tree Growth and Lacquer Quality

In order to improve the quality of the raw lacquer,we sprayed the lacquer tree nutrient solution with mineral elements(P,K,Cu,Mg,etc.) and plant growth regulators on the Maoba lacquer trees,then observed the growth of lacquer tree and tested the quality of raw lacquer.The results showed as follows:The lacquer trees in the treatment group flourish,barks are thicker,and the time of leaf shedding was postponed about half a month,with no side effect;the raw lacquer from the treated lacquer trees contained more urushiol,laccase and gum;the organoleptic index of the raw lacquer from the treated lacquer trees improved significantly;the surface drying time of raw lacquer from the treated lacquer trees was shortened.The main mechanism is that the lacquer tree nutrient solution changed the nutrient condition and improved metabolism.The nutrient solution can promote lacquer-tree and improve lacquer quatity.
