摘　　要：以茄子、节瓜、有棱丝瓜为材料,采用不同大小粒径的两种类型的保水剂育苗,研究保水剂对蔬菜幼苗质量以及保肥能力的影响。结果表明,育苗基质中保水剂浓度越高,育苗基质的保肥能力越强,但保水剂浓度过高时,会抑制蔬菜幼苗的生长,低浓度保水剂促进蔬菜幼苗生长效果明显,且小粒径保水剂壮苗效果优于大粒径保水剂,小粒径保水剂的浓度为1%时,育苗效果最佳,茄子、节瓜、有棱丝瓜幼苗的株高、茎粗、最大叶片面积均达到最大值,与对照相比差异达极显著水平。In order to investigate the stockosorb’s effect on quality of vegetable seedling and fertilizer-keeping capacity,different stockosorbs were adopted to seedings of eggplant（Solanum melongena L.var.serpentinum L.H.Bailey）,chieh qua（Benincasa hispida Cogn.var. chieh-qua How.）,towel gourd〔Luffa acutangula（L.） Roxb.〕.The result indicated that with the increase of stockosorb concentration in seedlings,the fertilizer-keeping capacity of seedling substrates increased.But too higher concentration might inhibit the growth of vegetable seedlings. The low concentration treatment could promote the growth of vegetable seedlings.Besides,the effect of small particles stockosorb was better than the big particles.When the concentration of small particles stockosorb was 1%,its effect on seedlings was the best.The plant height,stem diameter,leaf area of eggplant,chieh qua,towel gourd all reached the highest value.The differences reached the extreme significant level,as compared with the contrast.
