樟子松耐寒、抗旱、抗虫力强、根系发达、叶枝繁茂、防风作用强,在其他树种不能正常生长的干旱贫瘠的沙地上能茁壮生长,是陇东地区大力推广的良种。陇东北部沙区地处毛乌素沙漠南缘,属半干旱气候,多风干燥,年均降水量400毫米以下。樟子松容器育苗在甘肃省环县北部沙区特殊的条件下育苗,成活率低、难度大。一般采用容器育苗,这样可大大缩短育苗时间,延长造林季节,苗木质量好,产苗量高,保存率明显高于裸根苗,也是加快壮苗培育、提高荒山造林质量的有效途径。
Pinus sylvestris cold-resistant, drought-resistant, strong insect resistance, developed roots, lush foliage, strong windbreak, in other species can not grow in arid barren sandy land can thrive, is vigorously promote Longdong good seed. The sand area in the north of Gansu Province is located in the southern margin of the Mu Us Desert, belonging to a semi-arid climate with windy and dry conditions and annual precipitation below 400 mm. Pinus sylvestris container nursery seedlings in the sand area of northern Huanxian County, Gansu Province under special conditions, low survival rate, difficult. The general use of container nursery, which can greatly reduce the nursery time, extend the reforestation season, good seedling quality, high seedling production, the preservation rate was significantly higher than bare root seedlings, but also to speed up strong seedling cultivation, improve the quality of afforestation an effective way.
