| 摘 要： | 目的]为了研究草炭复配基质盐分含量对黄瓜育苗的影响.方法]采用草炭、蛭石、珍珠岩体积比3∶1∶1配制育苗基质,研究草炭复配基质盐分含量对黄瓜育苗的影响.结果]当基质盐分含量在1.5 ～3.0 g/kg（EC 1.2 ～2.9 mS/cm）时,黄瓜种子发芽和生长较好,叶面积、全株干重、壮苗指数、活力指数均达到较高值,且当盐分含量为3.0 g/kg（EC 2.9 mS/cm）时,活力指数、壮苗指数均最高;当盐分含量小于1.5 g/kg（EC 1.2 mS/crm）时,子叶较小,叶色浅,幼苗生长发育缓慢甚至停滞;当盐分含量大于4.5 g/kg（EC 4.0 mS/cm）时,叶色深绿、皱缩、边缘干枯,幼苗生长受到抑制;当盐分含量大于11.5 g/kg（EC 9.1 mS/cm）时,黄瓜种子不能出苗.结论]该研究可以为黄瓜育苗基质的盐分控制标准提供理论依据.

| Abstract: | Objective ] The aim was to discuss the effects of salt content of complex substrate on cucumber seedling. Method ] Peat, vermic-ulite and perlite （ volume ratio was 31 ： 1 ） which was added different content of salt were used as cucumber substrate. And the germination andthe amount of growth were studied. Result ] The cucumber seeds germinate and plant growth were better when the salt content was 1.5 - 3. ：5g/kg （ EC 1.2 - 3.5 mS/cm）, including the leaf area, total dry weight, seedling index and vigor index. When the salt content was 3.0 g/kg（EC 2.9 mS/cm）, the vigor index, and seedling index reached the peak. When the salt content was less than 1.5 g/kg （EC 1.2 mS/cm） ,the cotyledons were smaller, the leaf color was shallow, and the seedling growth was slow. When the salt content was greater than 4.5 g/kg（EC 4.0 mS/cm）, the leaf color was dark green and wrinkled, and leaf blades ran dry, then seedling growth was inhibited. When the saltcontent was greater than 11.5 g/kg （ EC 9.1 mS/cm）, the cucumber seeds couldn＇ t germinate. Conclusion ] The research could provide thetheoretical basis for the salinity control standard of the substrate of cucumber seedling. |
