【摘要】 用KLASMAN泥炭、熊猫牌泥炭、黄土、珍珠岩和蛭石等材料配制成不同基质,进行大花四照花容器育苗栽培试验。结果表明:各种配方基质的肥力等级均高;KLASMAN泥炭+熊猫牌泥炭+黄土(比例为2:1:1)配方的植株地径、苗高和叶片数最大,且叶片数与其它不同配方间的差异达极显著(P<0.01),最适宜容器苗生长;持水率高、镁元素含量高以及0.25~1.00 mm土壤颗粒含量高的基质不利于容器苗生长。更多还原

【Abstract】 In order to select the best substrate for the container seedling of Cornus florida,KLASMAN peat,panda peat,soil,perlite and vermiculite were mixed in different proportions to form 5 substrate formulations,which were used as growth media to study their effects on the C.florida.The results showed that the fertilizer degree of all formulations were high;the best formulation for C.florida was KLASMAN peat;panda peat:soil =2:1:1,which had the highest ground diameter,seedling height and leaf mumber,and leaf number showed high significant difference from other 4 substrates;the high water content,Mg content and 0.25 ~1.00 mm soil particle could effectively inhibit the growth of container seedling.更多还原
