包头西郊工业污染区盐渍土造林技术研究

以包头西郊防污林成活率、保存率、生长状况为依据，对工业污染区几种造林方法进行了比较研究。方差分析结果表明，植树坑中施绿肥造林、筑高台造林、水渠内造林是较好的造林方法，客土造林成活率高保存率低，常规造林成活率、保存率均低。因此，提出压绿肥造林，筑高台造林是工业污染区造林的主要方法。

STUDY ON AFFORESTATION TECHNIQUQ ON SALINIZED SOIL IN INDUSTRIAL POLLUTION REGION OF WESTERN SUBURB IN BAOTOU

Based on the survival rate,preserving rate and growth status of the forest for pollution control in western suburb of Baotou,seveval afforesting methods on the land of industrial pollution region were compared.The results showed that planting trees by using green manure in planting pits,making high platforms or planting trees in the ditches were the better methods.The suryival rate of planting trees in guest soil was high,preserving rate was lower,but the rates of survival and preserving in common soils were lower.Therefore,the afforestation of using green manure in the pits of making high platforms were the main methods in the industrial pollution region.
