摘要
对黑龙江省主栽的龙桑1号、桲椤桑、铁耙桑3个桑树品种的桑树,分别进行三个密度组合的栽植,实行二因素随机区组试验设计,通过对测定总产叶量统计分析,确定三个品种与密度的最佳组合,建议东北寒地北部选用龙桑1号桑与栽植1200株/667m2的组合建园;南部选用桲椤桑与栽植密度1000株/667m2的组合建设园。
Planting three varieties of mulberry,namely,Longsang 1,Boluosang,and Tiepasang dominating Heilongjiang province,by three combinations with different densities,the experiment design of two-factor randomly grouping was conducted.Through the statistical analysis of total leave yield,three combinations of varieties and densities were determined as the best ones.It is suggested that Longsang 1 be planted in the cold area of Northeast Heilongjiang,with the density of 1200 mulberry/667m2;while Boluosang be planted in southern Heilongjiang,with a density of 1000 mulberry /667m2.
