红叶李通常用嫁接法繁殖,压条、扦插次之。但近两年在生产实践中发现,沙藏育苗是一种很好的繁殖方法。沙藏育苗由扦插育苗变化而来的,具有很高的实用性和可行性,且成本低、效益高,适宜在生产中推广应用。苗床建造沙藏床应建在地势较高、通风良好、喷灌方便的地方,且需要一定的保温措施,有温室者更佳。沙床大小以育苗多少而定。一般插床下层铺10厘米厚的小石子,中层铺10厘米厚的碳渣,上层铺30厘米厚的粗砂,沙层基质用0.3%高锰酸钾或0.5%多菌灵溶液消毒,用薄
Hongye Li usually reproduce by grafting method, pressing, cutting second. However, in the past two years, it has been found in production practice that seedling raising in sand is a good breeding method. Sand seedlings from the cutting seedling changes come from, with high practicability and feasibility, and low cost, high efficiency, suitable for application in the production. Sand beds should be built on the topography, good ventilation, convenient sprinkler irrigation, and need some insulation measures, with greenhouse better. The size of the sand bed depends on the number of seedlings. Generally slotting shop 10 cm thick pebbles under the shop, the middle shop 10 cm thick carbon residue, the upper shop 30 cm thick sand, sand matrix with 0.3% potassium permanganate or 0.5% carbendazim solution disinfection, with thin
