不同密度毛竹林对土壤质量的影响

Effects of Different Densities of PHyllostachys Pubescens Forest on Soil Quality

通过对不同密度的毛竹林林下土壤调查,测定不同密度毛竹林土壤含水率、容重、总孔隙度等物理性状和pH值、有机质、速效氮、速效钾、速效磷等化学性状,研究了不同密度毛竹林土壤质量。当林分密度在2400株·hm-2时,土壤可以为毛竹林保障水分、养分条件,促进稳产高产,有利于今后的可持续经营。

Through the understory soil investigation of different densities of PHyllostachys pubescens forest,the pHysical properties such as soil moisture content,bulk density,total porosity and chemical properties such as PH value,organic matter,available nitrogen,available potassium and available pHospHorus were determined,and the soil quality of different densities of PHyllostachys pubescens forest was studied.When the stand density is 2400 plants·hm−2,the soil can guarantee the water and nutrient conditions for the bamboo forest,promote stable and high yield,and is conducive to the sustainable management in the future.
