摘要
对晚松进行营养袋育苗和带袋造林试验结果表明，采用营养袋育苗并带袋上山造林，初植成活率和年终保存率均在９０％以上，造林后第２年高生长量在２０ｃｍ以上，１～２次分枝数多，抗干旱能力强，其优点明显大于裸根苗造林，该育苗造林技术宜在雨量充沛、气候湿润的低山丘陵地区和农田防护林工程中推广应用，这将对加速荒山绿化后的补植及改善农田防护林树种结构有一定作用。
Experimeut on seedling cultivation by nutritional bag and forestation with bag of Pinus rigid indicated that it had over 90% survival rate after planlation and by the end of the year Height increment two years later was over 20 cm with many 1-2 time branches. and strong drought resistance. Forestation with bag had more advatages than forestation with here-root seedling.
