Seedlings Growth of Ilex fargesii on Different Nursery Container Media
Completely randomized block experiment design method was adopted to examined the effects of culture media on the growth of Ilex fargesii container seedlings that were planted in the media of humus, nursery soil and fine river sand.The results showed that the emergence rate, seedling height basal diameter, H/D, aboveground dry mass, under ground dry mass and root growth of container seedling presented significant differences among different media.The root vigor was also significantly different.The bulk density of the media and the content of soluble phosphorous were the major factors influencing the aboveground parts of the seedling growth;the bulk density and organic matter in the media were those influencing the underground parts of the seedling growth;the total porosity and pH had significant effects on the accumulation of the dry weight of seedling.According to the practical production, the recommended medium prescription was humus : nursery soil : fine river sand =50 : 25 : 25 for I.fargesii.
