无土栽培之不同基质的比较研究

Soilless culture comparative analysis of different base substances

通过对无土栽培不同基质的性质、经济成本和对植物生长的影响等3个方面进行比较分析,结果表明:沙、锯末、炉渣等是用途最广且经济的无土基质;岩棉、陶粒、蛭石、珍珠岩、浮石等是成本高、质量也好的高档次基质,是目前最好的无土基质;既经济又对植物生长有利的无土基质则是将上述两类基质合理混合使用。

The soilless culture comparative analysis was based on the characters, economical cost and effect on the plant?s growth.The results showed the economical and widespread soilless culture were sand, sawdust and slag;the high-cost high-quality and best soilless culture were cottonrock,ceramsite,vermiculte,pearlite,pumice stone. So the economical and good for plant?s growth were equitable mixed the two kinds of soilless cultures.
