不同基质配比对香石竹采穗母本生长的影响

摘要

为了研究不同基质配比对香石竹采穗母本采穗量和生长的影响，筛选出理想的基质配方，选取香石竹奥林匹克品种扦插苗为试验用苗，将椰糠、陶粒、草炭3种基质中的每两种按体积比1∶1、1∶1．5和1∶2分别进行配比，进行无土栽培基质试验研究。试验结果表明：香石竹奥林匹克采穗母本无土栽培基质配比以陶粒∶草炭＝1∶1．5为最佳。%In order to study the effects of different substrate ratios on the adopted seedling quantity and growth of carnation maternal plants, and to screen out the optimum substrate formula , we used the cutting seedlings of carnation variety “Olympic” as the tested materials, and mixed any two of three different substrates ( coconut bran, ceramsite and turf) at the volume ratios of 1∶1, 1∶1.5, and 1∶2) to conduct soilless cultivation experiment.The result showed that the best substrate ratio was ceramsite∶turf=1∶1.5 for the soilless cultivation of seedling-adopted carnation maternal plants .
