摘　　要：以红色和黄色2个秋葵品种为试材,研究了不同配比的草炭、蛭石和珍珠岩育苗基质对秋葵生长发育及产量的影响。结果表明:在草炭+蛭石+珍珠岩(1∶1∶1)的基质处理下,黄秋葵和红秋葵的壮苗指数、果实产量、根干重和前期产量都显著高于草炭+蛭石(1∶1)和草炭+蛭石+珍珠岩(2∶1∶1)处理;黄秋葵、红秋葵的壮苗系数分别为0.267、0.205,果实总产量分别为1 854、952g,根干重分别高出其它2个处理210.53%、132.50%,前期产量分别高出51.85%、90.22%。Taking okra and red okra two varieties as materials, the different ratios of peat, vermiculite and perlite were used as substrate,the effect of different seedling substrates on growth and yield were studied. The results showed that the growing medium containing peat＋vermiculite＋perlite （1 ： 1： 1） was significantly higher than other treatments on the seedling index of plant, the yield of fruit, root dry weight and early yield; seedling index of okra and red okra were 0. 267 and 0. 205,the yield of fruit were 1 854 g and 952 g,the root dry weight were 210. 53% and 132. 50% higher than other treatments,the early yield were 51.85% and 90. 22 % higher than other treatment respectively.
