摘　　要：通过小白菜穴盘育苗试验,研究以茶渣蚓粪为原料的育苗基质对小白菜幼苗生长的影响。结果表明:茶渣蚓粪复合基质中各处理的小白菜幼苗指标均优于对照处理(市场上常规育苗基质)。随茶渣蚓粪比例的增加,小白菜幼苗的株高、茎粗、SPAD值、根系各项形态指标呈先上升后下降的趋势。可见,利用适当配方茶渣蚓粪基质可明显提高小白菜幼苗的品质,处理配方可推荐用于小白菜工厂化育苗生产。Effects of tea-leaf wormcast as the raw material of seedling matrix on Chinese cabbage seedling growth were studied by using the hole tray seedling test. The results showed that Chinese cabbage seedling indices were higher in the treatments with tea-leaf wormcast complex substrate than those in the control （conventional seedling substrate in market）. With the increasing proportion of tea-leaf wormcast, the plant height, stem diameter, SPAD value and root morphology index of Chinese cabbage seedlings increased first, and then decreased significantly. This indicated that the substrate with the appropriate proportion of tea-leaf wormcast can obviously improve the quality of Chinese cabbage seedlings and can be as industrial production of Chinese cabbage seedling.
