摘要
对毛白杨苗木进行药物催根、不同根幅、植坑大小、栽植深度和不同肥料5个因子3位级正交试验,结果表明:最佳栽培方案是:根幅25～30cm,栽植穴直径60cm,根颈栽深60cm,追施氮肥。同时研究了苗木质量和修剪对其早期生长的影响,得出利于成活与生长一年生壮苗造林的结论。
An orthogonal experiment of three levels with five factors——deal-ing roots with chemicals,root extent,planting hole,depth of soil coveringtrunk,fertilizer,on Populus tomentosa nursery stock was carried out.Itshowed the optimum combination in all dimensional factors was:root extent25～30cm;planting hole 60×60×70cm;the depth of soil covering trunk 60cm(loam);topdressing nitrogenous fertilizer.Forestation with one-age nurserystock was favorable to surviving and growth.
