选用速生树种柠檬按造林替代紫茎泽兰试验以来,五年间共有三千多农户参加造林14636亩,控制害草面积达到8000多亩,经抽样调查造林成活保存率均达85％以上,紫茎泽兰生长密度降低了80％以上,其技术方法简单,而且经济省劳。新平县水塘、戛洒、腰街和漠沙等低热河谷地区,凡在宜林荒山或丢荒地,多被紫茎泽兰蔓延、侵占,严重地影响群众生产生活,长期困扰着人们的思想,成为农牧业十分突出的一个问题。根据省科委对开展紫茎泽兰防除途径课题的研究精神,我县自1984年开始,在热区选用柠檬桉造林替代紫茎泽兰试验以来,1984—1986年共有3062户(联户)造林14636亩,控制害草面积达8000多亩,经抽样调查造林成活保存率均达85％以上,紫茎泽兰的生长密度降低了80％以上,害草恶性蔓生的现象得到了明显的控制,现状大为改观。1987—1988年又完成柠檬桉造林面林9238亩,替代面积194亩,深受干部群众的欢迎。
Selection of quick-growing tree species Lemons replanting of A. adenophora test since the five years, a total of more than 3,000 farmers participating in afforestation 14,636 mu, control the grass area reached 8,000 mu, by sampling survey afforestation survival rate reached 85%, purple stem Zeeland growth density reduced by more than 80%, its technical method is simple, and economical and labor-saving. Xinping County, ponds, sprinkles, Yajie and desert areas such as low heat valley, where the barren hills or abandoned wasteland, mostly by Eupatorium spread, encroachment, seriously affecting people’s production and life, long plagued people’s thinking , Become a very prominent issue of agriculture and animal husbandry. According to the provincial Science and Technology Commission to carry out research on the path of E. adenophorum approach, since 1984, our county has selected 3052 households (joint-stock companies) from 1984 to 1986 to replace E. adenophorum in the hot zone, 14,636 mu of afforestation and 8,000 mu of grassland were controlled. Survival rates of afforestation and survival after sampling were all above 85%, and the growth density of Eupatorium adenophorum was reduced by more than 80%. Malignant sprawl of grasses was obviously controlled , The status quo greatly improved. From 1987 to 1988, 9238 mu of eucalyptus citri reforestation forest was completed, replacing an area of 194 mu, which was well received by the cadres and masses.
