【摘要】 本研究以大田原土为基本材料,通过添加不同比例的河沙、草炭、珍珠岩、蛭石,配制出5种不同的育苗基质。将这些基质填充到导根筒(直径10cm、长1m的PVC管)中以培育白榆(Ulmus pumila L)长根苗。通过分析比较不同育苗基质条件下白榆的地上部、地下部、总生物量及地下和地上部生物量等生长指标,在遵循育苗基质的适用性和经济性的基础上,筛选出培育白榆长根苗的适宜基质。结果表明,基质S3(大田原土60%+河沙10%+草炭10%+珍珠岩10%+蛭石10%)为最佳育苗基质。更多还原

【Abstract】 In this study,five different kinds of nursery substrates were produced using field soil as basic material with different proportions of river sand,peat,perlite and vermiculite material added.These substrates were filled into root-guiding tube(PVC tube with the diameter of 10 mm and the length of 1 m) to breed long root-seedling of Ulmus pumila L.Following applicability and economy of the nursery substrates,to select the suitable substrates for breeding long root-seedling of Ulmus pumila L,the growth of above-ground and below-ground,the total biomass and above-ground biomass/below-ground biomass etc of Ulmus pumila L were analyzed and compared on different substrates.The results showed that: substrate S3(field soil 60%+river sand 10%+ peat 10%+perlite 10%+vermiculite 10%) was the best nursery substrates.更多还原
