| 摘 要： | 对以３年生南岭黄檀为寄主的紫胶虫的幼虫期和成虫期进行喷施肥药试验。结果表明：适时合理的喷施、管理能提高紫胶的一、二级比例和放收比；幼虫期管理的最佳组合为紫胶虫固定后１０ｄ对寄主树根部每株施尿素２００ｇ、过磷酸钙５００ｇ，对固虫过多的细枝进行抹虫，并对树冠喷２．５％的稀土液；成虫期管理的最佳组合是紫胶虫涌散前６０ｄ施尿素２００ｇ／株，在树冠上喷１％Ｋ２ＰＯ４和４０×１０－６赤霉酸。

| Abstract: | The experimental results showed that the timely and rational spray management could raise the proportion of Grade One and Grade Two and the ratio of release to harvest of lac;in the larva stage,the optimal management combination was that ten days after the lac insect fixation,200g of urea and 500g of calcium superphosphate were applied to the root of each host tree,some lac insects were erased on the group branches with excessive fixed lac insects and meanwhile 25% of rare earth liquid was sprayed to the crown;and in the adult stage,the optimal management combination was that sixty days before the lac insect swarming,200g of urea were applied to each tree and 1% of K2Po4 & 40×10-6of gibberellic acid were applied to the crown. |
