摘要
为了解决忍冬种苗快速繁殖的问题,以3个新优忍冬品种为试材,研究了河沙、花泥、草炭土3种基质及是否使用生根粉对其扦插成活的影响。研究结果表明,不同扦插条件对忍冬品种成活及根系生长的影响不一,具体表现为:(1)‘金火焰’与‘垂红’在河沙中的扦插成活率最高,分别为89.6%和81%,而‘格莱姆’在河沙中的扦插成活率最低,仅为14.4%,而在花泥中的成活率最高,达74%。(2)3个品种在河沙中的根系发育均明显好于草炭土。(3)3个品种的生根粉处理生根率明显高于对照组,成活率提高16.6%,根系数量提升25.4%。(4)在不同基质中,‘金火焰’的总体成活率最高,根系数量均多于另外2个品种,而‘格莱姆’的总体扦插成活率最低。因此,‘金火焰’是最易扦插成活的忍冬品种,在河沙基质中,生根粉处理的‘金火焰’生根率可达96.4%。
In order to analyze the effects of different substrates on cutting propagation of three Lonicera cultivars, river sand, floral foam, peat and treatment with or without rooting powder were applied for cutting contrast tests. The results showed that, different substrates and rooting powder treatments had different effects on the growth and root development. (1) 'Jinhuoyan' and 'Dropmore Scarlet' had high cutting survival rate in fiver sand (up to 89.6% and 81%), but for cultivar 'Geleimu', the cutting survival rate in river sand was as low as 14.4%, while it could reach 74% in floral foam. (2) Compared with peat, river sand was more suitable for the root development of the three Lonicera cultivars. (3) With the treatment of rooting powder, the cutting survival rate of the three Lonicera cultivars increased by 16.6%, significantly higher than those in control group and the root quantity increased by 25.4%. (4) 'Jinhuoyan' had higher cutting survival rate and higher root quantity than the other two cuhivars in different substrates, while 'Geleimu' had the lowest survival rate. Therefore, ‘Jinhuoyan’ was the most suitable cultivar for cutting growth, the cutting survival rate could reach 96.4% in river sand with the treatment of rooting powder.
