摘 要:通过对通辽地区近5年内林木种苗基地数量、规模、造林面积、各树种苗木生产使用情况等进行调查的结果表明,通辽市国有苗圃规模最大,面积比较固定;个体苗圃规模最小,变化大;企业苗圃规模正逐步扩大。通辽市育苗生产总面积稳定,苗木质量和造林利用率均较高。主要造林树种杨树与锦鸡儿造林面积正逐渐减少,但同时较好的控制了杨树苗木生产量;针叶与经济林树种使用量正不断提高,致使经济林树种当地苗生产量已无法满足实际用量。The genetic by survey statistics of nearly five years seedling base number, afforestation area,scale,various species of seedling production such as the used in Tongliao,The state-owned nurseryhas the largest scale, the area is relatively fixed, the scale of individual nursery is the smallest and the change is great, and the scale of enterprise nursery is constantly expandingin our city. The city's total area of seedling production, stable quality and high utilization rate of seedling afforestation area; afforestation of Populus and Caragana sinica afforestation area is gradually reduced, but the reasonable control of production of Populus seedlings, expand the situation of forest tree species and coniferous species, economic forest seedling production cannot meet the actual amount of the phenomenon.
