摘要
针对榆林沙区盐渍化特点,在沙区采用不同植物种进行不同的整地方式、栽植技术以及生化制剂处理试验,并对这几种防治措施进行比较分析,认为沙棘、柽柳、河北杨和旱柳是盐渍化土地适宜树种;不同整地方式中沟垄低床效果较好,但费时费力;植物残体填充和深栽避盐造林成活率高、生长良好,操作简单,是盐渍化土地防治的有效措施。
According to the character of salinated land in desert area of Yulin,different soil preparation,planting techniques and chemical and biological treatments were applied for experimentation.Compared with these controls,Hippophae rhamnoides,Tamarix chinensis,Populus hopeiensis and Salix matsudana were proved to be the suitable tree species in salinated land.Among the different site preparation methods,low ridge bed groove performed better but took more time and labor.Pits filled with plant residuals together with deep planting to avoid salt contributed to higher survival rate,effective measure combination to prevent and control of salinization.
