摘要
为了提高红叶石楠快繁效率和种苗质量,降低生产成本,对红叶石楠穴盘嫩枝扦插自动弥雾育苗技术进行了研究.结果表明:扦插基质珍珠岩与蛭石的比例为3:1时,扦插苗根系最发达;400～600倍K2205生根粉浸泡处理插穗时,生根率最高;6月份,扦插生根率最高,可达96.5 %,生根时间最短,只有37.3 d;采用珍珠岩与蛭石(比例为3:1)作扦插基质,每日弥雾10次,繁苗效果最好.
To improve the efficiency and quality of the breeding of Photinia fraseri seedlings,lower the production cost,the rapid breeding technique of P.fraseri with auto-spraying system were investigated.The results showed that cutting medium supplemented with perlite and vermiculite(3∶1) could enhance the root system of the seedlings;Cuttings treated with K2205 rooting powder diluted by 400~600 times had highest rooting rate,this value was 96.5% in June and the shortest rooting time was only 37.3 d,auto-spraying 10 times a day in June was recommended.
