不同育苗整地方式及密度与毛白杨扦插苗生长关系的研究结果表明：在试验地条件下和试验密度范围内，不同育苗整地方式（垄作、平作）苗高、地径间差异极显著。经统计分析比较，垄作优于平作。育苗密度以6．65万株／hm2最佳。
The results showed that there was a significant difference in seedling height and diameter between seedlings and soil preparation under different experimental conditions and experimental density. After statistical analysis, the ridge is better than the flat. Seedling density to 6.65 million / hm2 best.
