摘  要：
研究了防热辐射和保湿技术对减轻沙地春季扦插枝条的热辐射温度伤害的机理,探讨了不同沙层温度的传导和变化规律及隔热材料和合适的水分对沙地不同沙层降低热辐射温度的影响。结果表明:"防热辐射技术"对降低表面沙层的高温胁迫有一定的作用,降低幅度为7.6%,"防热辐射和保湿技术"对降低表面沙层的高温胁迫有明显的作用,降低幅度为19%。应用该技术的旱柳扦插枝条的生长与对照相比,新生枝数提高2.5倍,平均新生枝长度提高6.8%,扦插成活枝条数提高2倍,成活率提高50%。

摘  要：
The mechanism of thermal radiation protection and moisturizing technology to reduce thermal radiation temperature injury on cutting branches in spring of sand soil were studied,the effect of variation,conductivity and insulation materials,suitable water on the different sand educe the radiation temperature were analyzed.The results showed that "thermal radiation protection technology" had some effect on reduction of high temperature stress of the surface sand layer,reduced 7.6%;"Defending heat radiation and moisturizing technology" had obvious effect on reduction of high temperature stress of the surface sand layer,reduced 19%.Growing of cuttaged dryland willow branch in "thermal radiation and moisturizing technology" compared with the contrast,the number of new branch raised 2.5 times,the average length of new branch raised 6.8%,the number of surviving cuttaged branch raised 2 times,survival rate raised 50%.
