摘要: 以蛭石、炉渣、细沙、珍珠岩和草炭等为原料,按照不同组合与配比组成复合基质,筛选适用于番茄穴盘育苗的基质配方。结果表明,以草炭、炉渣、蛭石为原料,按1∶1∶1的体积比配成基质,其容重和总空隙度均处于适宜育苗的范围,保肥性能强;并且该基质处理的番茄幼苗根际微生物数量和酶活性水平显著高于对照(草炭与蛭石,体积比2∶1),促进了番茄幼苗的生长,培育的番茄幼苗素质最佳,表现为番茄幼苗生长迅速、干物质积累快、壮苗指数大。因此,建议以草炭、炉渣、蛭石按1∶1∶1的体积比配制成复合基质,适用于番茄工厂化穴盘育苗生产。

Abstract: In the present study, several compound nursery substrates composed of vermiculite, slag, fine sand, perlite and peat in different combinations and ratios were selected for raising tomato seedlings in 72hole seedpans. It was shown that the substrate composed of peat, slag and vermiculite at the volume ratio 1∶1∶1 was suitable for tomato seedling growth. The rhizospheric microbial biomass and enzyme activity in tomato seedlings cultured in this substrate was increased compared to those seedlings cultured in control substrate, which was composed of peat and vermiculite at the volume ratio 2∶1. The increase of rhizospheric microorganisms and enzyme activities could promote tomato seedling growth. Consequently, the stem diameter, plant height, dry matter accumulation of seedlings in the above substrate were the biggest among all the tested substrates. In conclusion, the substrate composed of peat, slag and vermiculite at the volume ratio of 1∶1∶1 was beneficial for industrial seedling of tomato.
