摘要
[目的]了解毛乌沙漠樟子松浇水覆膜造林技术的成效。[方法]对该区樟子松进行了浇水覆膜、浇水不覆膜、不浇水不覆膜三种技术的处理试验,对比分析三个处理的成活率及生长量,并对樟子松浇水覆膜技术对土壤含水量的影响做了分析。[结果]樟子松的存活率和生长量浇水覆膜时最大,浇水不覆膜次之,不浇水不覆膜时最差;通过浇水覆膜能提高土壤含水量,土壤含水量的明显增加,直接影响樟子松的存活与生长。[结论]浇水覆膜这一造林措施可以获得良好的效益,对该技术的推广应用具有极其重要的实践价值和理论意义。
[Objective] To understand the planting effect of watering and film mulching of Pinus sylvestris var.mongolica in Mu Su Desert.[Method] The Pinus sylvestris var.mongolica in this area was respectively treated by three technologies of watering and film mulching,watering and no film mulching,no watering and no film mulching,the survival rate and increment of Pinus sylvestris var.mongolica under the three treatments were compared,and the effect of watering and film mulching on the soil moisture content was analyzed.[Result] The survival rate and increment of Pinus sylvestris var.mongolica were the largest under the treatment of watering and film mulching,then followed by the watering and no film mulching,and the smallest no watering and no film mulching;the technology of watering and film mulching could obviously improve the soil moisture content,and directly affect the survival and growth of Pinus sylvestris var.mongolica.[Conclusion] Excellent planting effect could be gained by the technology of watering and film mulching,whose popularization and wide application had significant practical value and theoretical meaning.
