花卉无土栽培基质筛选试验 总被引:9,自引:0,他引:9
选用了蛭石、蛭石 泥炭(1:1)、炉渣3种基质栽培花卉,对其用于花卉栽培的效果进行了对比试验,结果表明:蛭石、蛭石 泥炭所培养花卉的株高、花蕾数、花朵数、花径、单株鲜质量方面无显著差异,供试花卉生长良好;炉渣因其碱性大(经大量自来水冲洗,pH值仍在8左右),保水、保肥性能差,所培花卉在生长中、后期效果差,故炉渣不能单独作为基质使用。 相似文献

The effects of culture media and light intensity on in vitro growth of Oncidium ‘Aloha Iwanga‘ were investigated under CO2 enrichment condition. Height, fresh and dry weight of the Oncidium seedlings were measured, and the leaf number per plant, shoot number per plant, leaf width and leaf chlorophyll content were also investigated. The results were as follows: 1) The seedling height, fresh and dry weight, leaf number per plant, leaf width and leaf chlorophyll content of the shoots growing on MS complete culture medium were higher than those on 1/2MS, VW and 1/2VW media. The root number per plant and ratio of dry matter of the seedlings cultured on 1/2MS and 1/2VW media were higher than those on MS and VW; 2) The seedling height, flesh weight, dry weight, dry matter ratio and leaf chlorophyll content, leaf length, leaf width, root length, leaf number per plant, root number per plant of seedlings of Oncidium growing under 4 500 lx and 1 700 lx were higher than those under 750 lx. However, there was no significant difference in those growth parameters mentioned above while dealing with 4 500 lx and 1 700 lx except for the seedling height. Nevertheless, the leaf color of plants under 4 500 lx was lighter and the leaves of the lower parts became yellowish in comparison with those growing under 1 700 lx. 相似文献
