不同介质对桂竹香和香雪球种子发芽率及壮苗率的影响

Effect of the Different Mediums on Seed Germination Rate and Seedling Rate of Cheiranthus cheiri and Lobularia maritime

为了寻找合适的育苗介质,比较了加拿大Fafard系列纯泥炭和珍珠岩不同配比的3种介质理化特性的差异,分析了桂竹香和香雪球在3种介质上发芽率和壮苗率的差异。结果表明:泥炭与珍珠岩为2∶1的(B)介质播种时桂竹香和香雪球的发芽率和壮苗率最高,泥炭与珍珠岩为1∶1的(C)介质效果最差。

In order to find suitable medium of seedling, physicochemical characters of three kinds of substrates were studied,the differences in germination rate, seedling rate of the Cheiranthus cheiri and Lobularia mari- time in three kinds of mediums were analyzed. The results showed that germination rate and seedling rate of Cheiranthus cheiri and Lobularia maritime in the B（peats： perlite was 2 ： 1） medium were the highest, that in C（peats： perlite was 1 ： 1）medium was the worst.
