| 摘 要： | 主要研究了不同下垫面对侧柏经济价值的影响。试验表明,不同覆盖方式在不同土层深度条件下,土层温度随时间变化呈现出相同的"M"型趋势。在不同覆盖条件下,土壤总积温均随土层深度的加深而下降,不同覆盖条件土层总积温差异性显著,其中地膜和透水地膜的土层总积温值较高。

| Abstract: | This paper mainly studied different underlying surface influence on the economic value of Platycladus orientalis. The experiment showed that different covering methods, different depth of soil conditions, soil temperature change with time showed a tendency of ＂M＂. In different cover conditions, soil temperature decreased with the increase of soil depth, different mulching conditions, soil total accumulated temperature had significant difference film, and permeable plastic film of soil total accumulated temperature was higher. |
