【摘要】 采用L9(34)正交设计,选取栽植密度、施肥、覆膜作为试验因素,对造林第2年保存率、树高和地径生长量调查和统计分析的结果表明:采用每平方米栽培4株、覆大膜、不施肥组合方式进行栽培,蒙古栎生长性状最佳。栽植密度对地径生长影响显著,覆膜和施肥对地径生长影响不显著;覆膜对树高生长影响极显著,栽植密度和施肥对树高生长影响显著。更多还原

【Abstract】 Using L9( 34) orthogonal design,planting density,fertilization and film mulching were selected as test factors. We investigated survival rate,tree height and ground diameter increment and did some statistical analysis in the second year of the afforestation. The results showed that Quercus monglica grow well when planting four trees in every square meter,big film mulching and no fertilizer.Planting density had significant effects on ground diameter growth,but fertilization and film mulching were not significant effect on ground diameter growth. Film mulching had very significant effects on tree height growth,and planting density and fertilization were significant effects on tree height growth.更多还原
