吸水剂在退耕还林工程造林中的应用试验

Application Test on Water Retaining Agent in Conversion of Cropland to Forest

以中国沙棘为试验材料,研究了吸水剂在干旱地区退耕还林工程中应用的一些技术问题,结果表明:蘸根处理显著地提高中国沙棘造林的成活率与生长量,整地穴中预施吸水剂不如吸水剂泥浆蘸根效果好,因此,吸水剂蘸根造林是青海干旱地区退耕还林工程中值得推广的抗旱造林技术措施。

Some technology problem on water retaining agent in cropland to forest were studied with Chinese sea buckthorn,the results showed root-dipping could increase survival rate and growth significantly,the survival rate of pre-applied water retaining agent in planting cavity in preparation of land were inferior to that of root-dipping,so root-dipping by water retaining agent was worthy to popularize in drought-resistant afforestation in Qinghai.
