摘　　要：在黄泛沙地上进行毛白杨不同整地规格造林试验.结果表明:带状、穴状2种整地方式,8种不同整地规格,毛白杨幼林的胸径、树高生长量无明显差异,大规格整地对土壤容重和土壤含水率也无明显影响.但大规格整地显著增加造林成本,以挖60～80 cm见方的植树穴为宜.Poplar afforestation test with various soil preparation specifications was carried out in the sandy area of the Yellow River. The results showed that 8 different specifications of two ways of soil preparation with strips or holes had no significant difference in the growth of DBH, tree height of poplar trees, soil volume weight and soil moisture content. However, big specifications of soil preparation is relatively costly. So planting holes of 60 - 80 cm are recommended.
