中文摘要:永福唇柱苣苔(ChiritayungfuensisW.T.Wang)是苦苣苔科唇柱苣苔属下的一个种,产于广西的永福县,常生长在石灰岩的山阴处。苦苣苔科植物大多拥有较高的观赏价值,它们以矮小紧凑的结构、奇特有趣的叶片、硕大美丽的花朵以及良好的耐阴性而深受人们的喜爱。前期引种表明,这类植物观赏价值高、易获种源,又大多为多年生肉质草本植物,适应性观赏性强,易栽培,扦插繁殖较快,有较大的开发前景。本实验分析永福唇柱苣苔的生物学特性、园艺特性,根据永福唇柱苣苔的观赏性,比较试验盆栽基质,分析不同基质(椰糠、珍珠岩、蛭石、草炭及其不同混合比例)、植株的生长量、矿质养分含量,基质的理化性质。62078 毕业论文关键词:永福唇柱苣苔;盆栽基质;生长量;养分含量 Ornamental evaluation and screening of potting mix for Chiritayungfuensis Abstract: Chiritayungfuensisis One kind Gesneriaceae Branch under the Chirita, Produced in Guangxi Yongfu, born in limestone at Sanin. Gesneriaceae most of which have high ornamental value. They dwarf compact structure, singular interesting leaves, huge and beautiful flowers and unique shade tolerance and loved by the people. Pre-show introduction and cultivation, Such plants high ornamental value, easy to get provenance, and there is a perennial succulent herb, adaptability, easy cultivation, ornamental strong, growth is relatively goodadaptability, cutting propagation is relatively fast, with great market development prospect. The experimental analysis of the biological characteristics of Chiritayungfuensis, gardening characteristic analysis Chiritayungfuensis ornamental, potted matrix comparison test, analysis of different substrates(Coco peat, perlite, vermiculite, peat and different mixing ratio), Physical and chemical properties of the plant growth, mineral nutrient content and physical and chemical properties of the matrix.
