摘要
为研究不同基质对罗汉果无糖组培苗的影响,试验以 6种不同基质对罗汉果无糖组培苗进行移栽炼苗试验,比较不同育苗基质对罗汉果无糖组培苗移栽炼苗的影响.结果表明,处理 3基质植株生长最快、叶片最大、根系发达,但部分品种出现不明原因失绿且补肥效果有限,不是罗汉果最适合基质.处理 6为全价育苗基质(纯草炭土型):珍珠岩:碳化稻壳=2:1:1,该基质种植的种苗生长速度仅次于处理 3,且整个育苗期罗汉果生长健壮,根系发达,是试验中最适合罗汉果无糖苗移栽炼苗的基质.此基质在不同季节均适用,在冬季使用效果更加明显,添加碳化稻壳使基质疏松、透气、颜色变深,多吸收太阳热能,提高土温,更有利于根系生长.
Abstract
In order to study the effects of different substrates on sugar-free tissue culture seedlings of Siraitia grosvenorii,six different substrates were used to transplant sugar-free tissue culture seedlings of Siraitia grosvenorii,and the effects of different substrates on sugar-free tissue culture seedlings of Siraitia grosvenorii were compared.The results showed that treatment 3 had the fastest plant growth,the largest leaves and developed roots,but some varieties lost green for unknown reasons and the effect of fertilization was limited.Siraitia grosvenorii is not the most suitable substrate.Treatment 6 is the full price seedling substrate:perlite:carbonized rice husk=2:1:1,the growth rate of seedlings planted in this substrate is only second to that of treatment 3,and Siraitia grosvenorii has strong growth and developed roots in the whole seedling period,which is the most suitable substrate for transplanting sugar-free seedlings of Siraitia grosvenorii in this experiment.This substrate is suitable in different seasons,and the effect is better in winter.The addition of carbonized rice husk makes the substrate loose,breathable,darker,absorb more solar heat,increase soil temperature,and is more conducive to root growth.
