木棉苗期生长基质筛选研究

Substrate Selection for Bombax ceiba Seedling Cultivation

选用9种不同类型基质盆栽木棉幼苗,比较不同基质对木棉苗期生长的影响,进而筛选出适合木棉苗期生长的营养基质。结果表明:不同类型基质对木棉幼苗成活率、苗高、地径及生物量等的影响存在显著差异,木棉适合在土壤容重大、含水量和总孔隙度较小、pH较大的土壤基质中生长,基质M7(50%黄心土+50%塘泥)和M3(50%泥炭土+50%塘泥)为木棉苗期培育较适宜的营养基质。

9 different types of substrates were tested for Bombax ceiba seedling pot culture to screen out the right one by comparing the effect of the varied substrates on the growth of B. ceiba seedlings. It was found that the substrates presented significant influences on the survival rate, height, basal diameter and biomass of the seedlings. The study showed that B. ceiba seedlings could grow better in the substrates with bigger bulk density, less moisture content, total porosity, and higher pH value. Further analyses revealed that the substrates No. 7 （50% yellow soil ＋ 50% waterlogged compost soil） and No. 3 （50% peat soil ＋ 50% waterlogged compost soil） were more suitable for the cultivation of B. ceiba seedlings
