摘要
在太行山南部石灰岩中山区,以侧柏2年生幼树为研究对象,选择地膜、生态垫、秸秆、石块等材料进行覆盖保墒试验,用EM50自动测定土壤含水量,在生长期结束后对侧柏地径、苗高、生物量、成活率进行调查。试验结果表明:覆盖石块、渗水地膜能起到明显的保墒作用,茎、叶、总生物量、幼树高生长量明显高于其他处理,地径、主根、侧根的生长受影响不大。
Taking 2-years-old Platycladus orientalis saplings as the research object,plastic film,eco-mat,straw,stone,etc.were selected to be conducted mulching experiment to keep moisture in calcareous rock area in middle Taihang mountain.Soil water content was measured by using EM50;ground diameter,seedling height,biomass survival rate were investigated after the end of growing season.Result shows that mulching with stone water-permeability plastic film can play the role of moisture conservation obviously;stem biomass,leaf biomass,total biomass height volume growth of sapling which were mulched with stone water-permeability plastic film are significantly higher than that by other treatments,but the growth of ground diameter,main root and lateral root are not affected distinctly.
