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。
An orthopnal experiment of three levels with five factors-dealing roots with chenicals,root extent,planting hole,depth of soil covering trunk,fertilizer,on Populus tomentosa nursery stock was carried out.The result showed that the optimum combination in all dimensional factors was:root extent 25~30cm;planting nitrogenous fertilizer.
