摘要
通过对黄波椤播种育苗留苗密度与苗木质量关系的研究,结果表明:黄波椤播种育苗留苗密度对苗高生长量影响较小,对地径生长量和总生物量影响较大;在垄作和床作播种育苗中以70~90株m^(-2)为适宜;床作育苗较之垄作育苗生长量大。
The relationship between seedling density seedling quality of Phellodendron amurense was studied. Result shows that 70 - 90 plants m-2 is suitable for ridge planting ＆ bed planting. The density has little effect on height growth） but have great influences on growth of ground diameter total biomass. The growth of bed nursery is higher than that of ridge nursery.
