摘要
扦插繁殖是保持园林植物优良性状的重要繁殖方法之一,为研究浙江红山茶在黄山地区高效扦插繁殖的基质,采用随机区组设计的方法,选用黄心土、河沙、蛭石与珍珠岩混合物等为三种不同扦插基质,研究不同基质对浙江红山茶扦插成活率、生根性状和生物量组成的影响。结果表明:不同基质对扦插成活率有一定影响,但差异不显著,对根条数、根长及根重也有影响,以蛭石混合基质上根条数最多,而河沙上根的平均长度最大,黄心土上根重最大,因而不同基质对生根的影响各有不同,从生物量分配来看,以黄心土上的根茎比最大,综合来看,在黄山地区黄心土是较为合适的扦插基质。
Cutting propagation is an important way to remain fine characters of garden plants,in order to select efficient cutting media at Huangshan distract for Camellia chekiangoleosa Hu,the article employed randomized block to study the influence of cutting media（yellow soil,sand and mixed media by vermiculite and perlite） on survival rate character of root and biomass composition.The results showed： there were some way difference on survival rate at different cutting media,but the different was not remarkable,and there some way difference on number of root per plant and length of root and the composition of biomass.The maximum number of root was observed at mixed media by vermiculite and perlite,the maximum length of root was observed at sand,and the maximum weight of root was observed at mixed media by vermiculite and perlite,therefore the influence on character of root at different media was different.The ratio of root to stem was largest at yellow soil.Generally yellow soil is a suitable cutting media for Camellia chekiangoleosa Hu cutting propagation at Huangshan disract.
