摘　　要：为提高桂花扦插效果,生产出数量大、质量优的桂花苗木,以银桂嫩枝为材料,设置普通苗床、立体苗床及架空苗床3种插床进行了扦插试验,比较了扦插苗生长情况。结果表明:扦插苗床对桂花扦插苗生根率和新梢长度有明显影响:立体繁育苗床插穗成活率最高、新梢长度最长,分别为95.35%、5.94 cm;扦插苗床对银桂插穗根条数、根长度影响不明显。采取立体繁育苗床进行桂花嫩枝扦插,其扦插效果最好。To improve the cutting effect of Osmanthus fragrans and produce large quantities of high-quality Osmanthus fragrans seedlings,three types of seedbeds,namely ordinary seedbeds,three-dimensional seedbeds,and elevated seedbeds were set up,and cutting experiments were conducted to compare the growth conditions of Osmanthus fragrans cuttings.The cutting seedbed had a significant effect on the rooting rate and shoot length of Osmanthus fragrans cuttings,with the three-dimensional breeding seedbed having the highest cutting survival rate and the longest shoot length,which were 95.35%and 5.94 cm,respectively;root length had no obvious effect.The three-dimensional breeding seedbed is used for the best cutting effect on Osmanthus fragrans tender branches.
