摘  要：
采用造林技术于冻结滞水理论技术相结合的方法,研究树木根系发育分布与冻结滞水的相关性,为防治荒漠,提高造林成活率提供理论技术依据,研究结果表明,苗木和高秆造林树木根系主要分布在地表以下20 cm~75 cm深度内,即冻结滞水富水带内,含水量达40%~50%,春季冻融水满足苗木生根成活的要求.80 cm~160 cm深度分贫水带,含水量〉5%,高杆造林树木根系极少.到160 cm~200 cm含水量增加,发育,第二层根系。冻结滞水资源是提高苗木成活率,生存繁的重要水资源。

摘  要：
Adopting the mehtod of the forestation technology combined with the freezing stagnant water technology theory,the relationship between root growth distribution and the freezing stagnant water was studied to provide the theory technology basis for preventiog and controlling wilderness and enhancing the survival rate of trees planted,The result indicated that nursery stock root and high stem forestation trees mainly distribute within 20cm~75cm in the below surface depths.Namely,in freeze stagnant rich water,The water content amount to 40%~50%,freezing melt water in spring can satisfied the request of nursery stock taking root and surviving.80cm~160cm depth is the poor water zone.The water content<15%,The water content of high stem forestation trees is extremely short.The water content increases in 160cm~200cm,the second layer root system was developed.Freezing stagnant water resource is important water resource to improve nursery stock survival percentage.
