【摘要】 通过对青海省部分地区白云杉两年的引种试验研究,结果表明:白云杉在青海少数高山地区和繁殖圃生长表现良好,其它地区表现较差,主要为干梢严重、保存率下降等,适应种植范围小;相关性分析表明:当地环境因子对白云杉的高度、地径生长状况有很大影响,影响效果为:降雨量>坡向>土壤肥力>海拔。更多还原

【Abstract】 The introduction of Picea glauca for two years in parts area in Qinghai was studied.The result showed that the growth performance of Picea glauca is positive in minority alp and propagate garden in Qinghai,but negative in others area,the major problem are these: the tip seriously dried,the ratio of survive is low,the feasible plant area is small.The reletivity analysis showed that the height growth and the diameter growth are significantly effected by environment factors.The factors order is rainfall>slope direction>soil fertility>altitude.更多还原
