| 摘 要： | 通过对不同下垫面（自然裸露、尼龙薄膜覆盖、稻草覆盖）竹林地土壤温度的连续观测，分析了冬季土壤热状况的时空变化规律，比较了不同下垫面对土壤热状况的影响，建立了自然裸露和覆盖处理之间土壤温度变化的数学关系式，认为稻草覆盖的保温效果最佳，并在低温条件下更加明显．同时，观测了不同下垫面对出笋期的影响

| Abstract: | Through continuous soil temperature observation of different underlying covers(nutural,nyion film and rice straw cover )in the bamboo garden,time and space change regular of soil thermal condition in winter were analyseed.Effects of different covers on soil thermal condition were compared,mathematical models of soil temperature change between nutural and the other two covers were set up.It indicated that the measure of thermal insulation is rice straw cover and higher winter temperature is useful to advance date of bamboo shoot emergence. |
