摘　　要：以紫胶蚧优良寄主植物久树为研究对象,采用比较研究法研究了其种子育苗技术、造林技术、枝条利用及紫胶蚧在寄主植物上生物学特性。研究结果:破壳处理可极大提高种子发芽率,一般在开春(3月)采用容器育苗,雨季初期(6—7月上旬)造林;造林地应选择土层深厚、土壤通透性好的山坡中、下部,阳坡效果更好;雨季前松土除草和追施氮肥相结合,可明显促进幼树生长;久树是紫胶蚧最优良寄主植物,冬、夏代放养结果稳定,既适于保种又适宜产胶,寄主植物每年可利用1次。Comparison research trial was conducted on Schleichera oleosa as lac host, including technology of seeding,afforestation, branch utilization and biological characteristics of Kerria lacca. The results showed that seed germination rate could be increased with the way getting rid of the capsule. Seedlings were raised in March and plant at the beginning of monsoon( It is about June and the first ten days of July in Yunnan province). The land suitable for the tree should be deep and loose soil and right drainage condition such as mid and low area of hillside. Afforestation effect could be better if the tree was planted at the south side of the hill. Young sapling could grow better with scarification and weeding and fertilizer superaddition. Schleichera oleosa was the best host tree for Kerria lacca and the output of lac was stable at winter and summer generations. It was also a favorable tree species for both keeping brood lac and for producing lac and it could be utilized by Kerria lacca once a year.
