摘要
进行不同激素处理、留叶程度、扦插基质、扦插繁殖期、不同荫蔽度对金花茶生根成活率影响试验。结果表明:激素处理、留叶程度、扦插基质、扦插繁殖期、不同荫蔽度对金花茶生根成活率都有显著的影响。其中影响最大的是荫蔽度和插穗留叶程度。在桂北地区,金花茶最适宜的扦插时间是4月中旬;采用留2片叶的一年生枝插穗以100 mg.L-1NAA激素处理18 h后插于黄泥土基质的插床中,荫蔽度为90%,其成活率最高。
The effects of different hormone processing,remain leaves,substrate,cutting time and light intensities on survival rate of Camellia nitidissima were investigated. The results showed that there were remarkable effects on survival rate of C. nitidissima with different hormone processing,remain leaves, substrate,cutting time and light intensities,especially light intensities and remain leaves. The most suitable time for cutting C. nitidissima in northern Guangxi is in the middle of April. It can get higher rooting rate of cutting by using one year shoot with two leaves on the top ,dipping the cuttings in concentration of 100 mg·L^-1 NAA for 18 h,yellow soil as medium for cutting bed and 90% for light intensities.
