摘　　要：[目的]以无籽西瓜为试验材料,对6种不同类型的育苗基质进行了比较试验,以期进一步提高无籽西瓜育苗的成苗率。[方法]对各基质的理化指标和无籽西瓜苗期的生长指标进行检测。[结果]草炭∶蛭石∶珍珠岩3∶1∶1表现最好,无籽西瓜种子出苗势达85.6%,出苗指数为16.8,出苗率为86.7%,成苗率为80.6%,前期生长良好。[结论]以草炭和椰糠为主原料的具有低容重、高孔隙度、低EC值和养分水平的基质类型更有利于无籽西瓜出苗。[Objective]Seeds of seedless watermelon were planted in six kinds of substrates,which purposed to improve the seedling rate of seedless watermeton.[Method]The physical and chemical characteristics of substrates and the growth indexes of seedless watermelon seedlings were tested.[Result]The emergence rate of seedless watermelon was best in peat∶vermiculite∶perlite(3∶1∶1);The seedling emergence power of seedless watermelon seeds reached 85.6%;The emergence index was 16.8;The emergence rate was 86.7%;The seedling rate was 80.6%;The previous growth of seedless watermelon seedlings was well.[Conclusion] The matrix of peat and coir dust as main raw materials was more conducive to seedless watermelon emergence which have low density,high porosity,low EC and nutrient level.
