轻度盐碱地杨树造林技术的研究

通过在通榆盐碱地区杨树 5种整地方式造林对比及杨树钻孔造林试验表明 :在轻度盐碱地上杨树造林成活率低 ,生长缓慢 ,主要原因是由于土壤含盐量高 ,pH值大 (pH >8) ,且土质粘重 ,透水透气性差 ,限制了根系对水分、养分的吸收。用机械深翻、深松 ,筑高台对土壤的理化性质影响不大 ,通过雨水淋溶对降低土壤含盐量效果不明显 ,试验结果显示 :轻度盐碱地造林应以传统造林为主

Planting techniques of poplar in slight alkaline soil

Comparison test of 5 land preparations and hole borng planting showed,that mechanical preparation,deep plonghing and bunding less effected on soil physical and chemical properties,and the effect of rain leaching also was not clear.Planting on alkaline land should put traditional ways first.
