| 摘 要： | 利用野外控制试验的方法,开展不同郁闭度天然锐齿栎林下苦荬菜密度梯度的种植试验.结果表明,在锐齿栎-苦荬菜的林菜复合经营体系中,锐齿栎林分郁闭度和苦荬菜种植密度对苦荬菜地径的影响不大;但显著影响苦荬菜的株高、地上部分生物量和产量;苦荬菜株高和单株生物量随着林分郁闭度和种植密度的增大均呈下降趋势,但苦荬菜产量随种植密度的增...

| Abstract: | Effects of planting density on base breast,height and biomass were investigated under Quercus forest of different canopy openness using control experiment method in this paper.The results indicated canopy openness and planting density had no significant effects on the base breast of Ixeris denticulata(Houtt.)Steb,but strongly affected the height,biomass and yield of Ixeris denticulata(Houtt.)Steb.The biomass and height of Ixeris denticulata(Houtt.)Steb decreased with planting density and canopy openness inc... |
