摘　　要：以茶渣蚓粪为原料,与泥炭、珍珠岩、蛭石按不同体积复配成育苗基质处理1(1∶5∶2∶2)、处理2(2∶4∶2∶2)、处理3(3∶3∶2∶2)、处理4(4∶2∶2∶2)、处理5(6∶0∶2∶2)进行番茄育苗试验,通过分析番茄穴盘育苗植物学性状指标,探讨茶渣蚓粪基质在番茄育苗上的应用效果。结果表明:除处理1外,其他茶渣蚓粪复合基质处理下的番茄幼苗生长指标均优于对照处理(市场上常规育苗基质),其中以处理4效果最好,处理5次之。随着茶渣蚓粪比例的提高,番茄幼苗的株高、茎粗、SPAD值、根系形态指标呈先上升后下降的趋势。在本实验中,采用适当配方的茶渣蚓粪基质可明显提高番茄幼苗的品质,以处理4的番茄幼苗各项指数均为最好,可推荐用于番茄的穴盘育苗生产。The tomato seedling experiment was conducted to investigate the effect of substrate on the tomato seedling growth from five propor-tions of tea-leaf wormcast to peat, perlite and vermiculite, namely treatment I（1∶5∶2∶2）, treatmentⅡ（2∶4∶2∶2）, treatmentⅢ（3∶3∶2∶2）, treatmentⅣ（4∶2∶2∶2）, treatmentⅤ（6∶0∶2∶2）, respectively. The botany properties and characters of tomato seedling were observed to dis-cuss the application effect of tea-leaf wormcast substrate. The results showed that in all treatments of the compound substrate of tea-leaf wormcast, except of treatment I, the tomato seedling indexes were superior to the control treatments（conventional seedling substrate in mar-ket）, and the treatments Ⅳ had the best effect, followed by treatment Ⅴ. With the increasing proportion of tea-leaf wormcast, the plant height, stem diameter, SPAD value, and root morphology index of tomato seedlings firstly increased, and then decreased obviously. The sub-strate with the appropriate proportion of tea-leaf wormcast could obviously improve the quality of tomato seedlings, and the treatmentⅣwas the best, which could be recommended for the actual production of tomato seedling.
