Effect of Different Substrates on Seed Germination andSeedling Growth of Three Lauraceae Plants

摘要:

摘要：以河沙、草木灰、锯末配成的三种栽培基质为试验材料，以黑壳楠、楠木、闽楠为供试品种，采用露天播种育苗的方式，研究不同基质对三种樟科植物种子的萌发、幼苗生长情况的影响。结果表明：黑壳楠在河沙中的发芽率、发芽指数最高，幼苗生长情况最好；楠木和闽楠在河沙+草木灰的基质中萌发情况和幼苗生长情况最好。

Abstract:Using three growing media dubbed by sands, plant ash and sawdust as experimental materials, the paper made a study of the influences of different substrates on seed germination and seedling growth of Lindera megaphylla, Phoebe zhennan and Phoebe bournei in the open-air planting nursery. The results showed that the germination rate, germination index and seedling growth of Lindera megaphylla was best in the substrate of sand. The germination rates, germination indexes and seedling growths of Phoebe zhennan and Phoebe bournei were best in the substrate mixed by sand and plant ash.
