摘要
浙北涂区杨树林分的调查结果表明:除土壤盐分外,土壤容重、非毛管孔隙等土壤物理性质也明显地影响着杨树的生长;用土壤全盐量来表示杨树的耐盐力.常具有较大偏差。而用土壤水的盐分浓度示,更符合客观性和更具有实用性,经实地测得该值为0.45%时,杨树的生长就受到明显的抑制。同时,对地下水与杨树生长的关系作了初步探讨。
Investigation on poplar stand in tideland region of Northern zhejiang showed that soil physical properties like soil apparent density,no-capillary pore,etc.had influence on poplar growth besides soil salt status.It had deviation to express salt-endurance of poplar with soil total salt,but with,soil water salt concentration,it showed more practicable.when this value was 0.45%,poplar growth was evidently checked.Meanwhile,Preliminary discussions were made on relationship between subsurface water and poplar growth.
