刺槐种子小蜂是危害刺槐种子的重要害虫之一。如眉县南寨刺槐林,种子被害率一般在20%左右,部分结实量大的疏林地和孤立木,受害率高达50%以上,直接影响到育苗造林所需的种子。为了落实毛主席关于“实行大地园林化”的指示,加速我省绿化步伐,一九七二年陕西省林木病虫害防治座谈会决定,将刺槐种子害虫防治试验列为我省科研项目之一,并责成柳林林场、槐平林场和省农林学校共同承担这项科研任务。一年
Robinia pseudoacacia seeds is one of the important pests that endanger Robinia pseudoacacia seeds. Rumao Nanzhai Robinia pseudoacacia forest, seed damage rate is generally about 20%, part of the strong sparse woodland and isolated wood, the victimization rate as high as 50%, a direct impact on the seedlings needed for seedling afforestation. In order to implement Chairman Mao’s instructions on “implementing the practice of earth gardens” and speeding up the pace of afforestation in our province, the forum on prevention and treatment of forest pests and diseases in Shaanxi Province was decided in 1972 to include the locust pest control test as one of the province’s scientific research projects Obligations Liulin Forest Farm, Huai Ping Forest Farm and the provincial agricultural and forestry schools share the task of scientific research.
