选择4个杞柳优良品种,采用完全随机区组和裂区试验设计,进行多点不同品种、不同密度的造林对比试验,对其密度和品种间产量差异进行对比分析.结果表明,密度与品种对单位面积产量有显著影响;同一品种在3种初植密度下以0.30 m×0.10 m为最优密度;同一密度不同品种间产量差异显著.%Choosing 4 excellent varieties of Salix integra, the afforestation comparison test of different varieties and different density was carried out by using complete randomized block and split plot design. Hie yield difference was compared among different varieties and different density. The results showed that the density and variety had significant effects on the yield per unit area. The optimum density for the same variety was 0.30 m×0.10 m among three initial planting density. The yield at the same density had significant difference among different varieties.
