女贞树(Ligustrum lucidum Ait)是白蜡虫的优良寄主之一。近年来,白蜡生产迅速发展,寄主资源远远不能满足生产的需要,但在白蜡生产中,往往由于养树用树不合理,造成了大量寄主树老化,严重影响了白蜡的生产。为解决以上问题,我们采用切干更新措施,使女贞树一年更新复壮,第二年即可投放白蜡虫。现将试验情况介绍于下。一、试验地概况试验地设在云南省墨江县回冲、车路和大冲队,海拔1,289米左右。此地属南亚热带气候,年平均气温17.8℃,≥10℃年积温6,263.6℃,年降水量1,361.0毫米,年蒸发量1,682.5毫米,年日照2,132.5小时,年平均相
Ligustrum lucidum Ait is one of the fine hosts of waxworms. In recent years, the rapid development of white wax production, the host resources are far from meeting the needs of production, but in the production of white wax, often due to unreasonable tree-raising, resulting in a large number of host aging, seriously affected the production of white wax. In order to solve the above problems, we adopted cutting-off renewal measures so that the Ligustrum tree can be renewed and rejuvenated year by year and the white wax insect can be put into use the following year. The test situation is introduced below. First, the experimental site The experimental site is located in Mojiang County, Yunnan Province, back flushing, road and large red team, 1,289 meters above sea level. Here is a subtropical climate, the annual average temperature of 17.8 ℃, ≥ 10 ℃ accumulated temperature 6,263.6 ℃, the annual rainfall of 1,361.0 mm, the annual evaporation of 1,682.5 mm, 2,132.5 hours of annual sunshine, the average annual phase
