芳樟扦插育苗季节与基质的试验研究

芳樟是经良种选育的油用林优良品种,只有采取无性繁殖才能保持母本优良性状。在厦门开展不同扦插时间、基质的育苗试验,结果表明:8～10月是适宜扦插的时间,如任务繁重可延续到11月扦插;3～6月由于穗条木质化原因,扦插成活率低,不适合扦插育苗。4种基质的扦插成活率差异不显著,采用泥碳土20%:锯末20%:黄心土57%:过磷酸钙3%的配方处理扦插成活率最高,可达88.07%。

Study on Experiment of Cuttage Season and Matrix of Cinnamomum camphora

Cinnamomum camphora is a fine breeding variety of oil use forest, only asexual reproduction can maintain the fundamental character of female parent. In Xiamen, matrix cutting seedling test in dif- ferent season has been conducted, the results shows that： the suitable cutting time is from August to Oc- tober, if the task heavy, it can last to November; due to the strip lignifications from March to June, cut- ting survival rate is low, not suitable for cutting seedling. The differences of cuttage survival rate are not significant in four cottage matrix, the formula of soil carbon account for 20 % ： sawdust 20 % ： yellow soil 57 % ： calcium superphosphate 3% is the best which cutting survival rate can reach to 88.07%.
