摘要
为了保护和利用祁连山湿地野生水柏枝属植物资源,实现人工繁殖和栽培,调查了其种类、形态和分布,开展了播种、扦插和分株繁殖试验.结果表明:祁连山湿地共有水柏枝属植物3种,分别为匍匐水柏枝、河柏、具鳞水柏枝.其中具鳞水柏枝自然繁殖特性、种子沙藏播种、吲哚乙酸处理扦插试验中均表现最好,建议优先繁殖具鳞水柏枝来满足生产需求.不同繁殖方法中IAA处理插条后生根率可达75.33％～86.00％,可优先用于苗木繁殖;根蘖苗截干后移栽成活率可达42.67％～52.00％,可用作繁殖候选方法;种子沙藏后发芽率仅为21.00％～30.67％,发芽率有待提高,建议暂不用于苗木繁殖.
Abstract
To protect and utilize plant resources of Myricaria Desv.in Qilian Mountain wetland,realize ar-tificial propagation and cultivation,species,morphology,and distribution were investigated,and the sowing,cuttings and division propagation experiments were performed.The results showed there were 3 species of M.Desv.in Qilian Mountain wetland,namely M.prostrate Hook.f.et Thoms.,M.bracteata Royle,and M.squamo-sa Desv..Among them,the natural reproduction characteristics of M.squamosa Desv.,whose stored with sands and cutting treated with indoleacetic acid were the best in different species,which should be recommended to prioritize the reproduction of M.squamosa Desv.to meet production needs.The rooting rate of IAA-treated cuttings were 75.33％～86.00％,which can be prioritized for seedling propagation.The survival rate of root tiller seedlings transplanted after pruning can reach 42.67％to 52.00％,which can be used as a candidate method for reproduction.The germination rate of seeds stored in sand was only 21.00％to 30.67％,and the germination rate needs to be improved.It is recommended not to use it for seedling reproduction temporarily.
