摘要
为探索适合辽西半干旱区油松的最佳造林方式,对容器苗造林、塑料袋保苗造林、裸根造林3种方式进行比较试验。结果表明:容器苗造林方式下苗木保水性好,造林的成活率及保存率最高,造林的成本显著低于裸根造林;塑料袋保苗造林方式下苗木的保水性、成活率等均好于裸根造林方式,其造林成本最低。
In order to explore the effect of container seedling afforestation in semi-arid areas of western Liaoning Province, container seedling afforestation, plastic bag seedling afforestation and bare root afforestation were compared. Result shows that in the mode of container seedling afforestation seedlings have optimal water retention. The survival rate & preservation rate of afforestation are the highest, the cost of afforestation is significantly lower than that of bare root afforestation;the water retention and survival rate of seedlings in the afforestation mode of keeping seeds by plastic bags are optimal than those of bare root afforestation;the afforestation cost is the lowest.
