红叶李是园林绿化中常见的彩叶植物,具有较强的观赏价值,一般用嫁接繁殖,压条繁殖和扦插繁殖次之。在近年的生产实践中发现,沙藏育苗也是红叶李比较好的繁殖方法。沙藏育苗由扦插育苗发展而来,具有较高的实用性和可行性,而且成本低、效益高,值得在生产中推广应用。一、沙藏育苗1.苗床建造。沙藏苗床应建在通风良好、地势较高、喷灌方便的地方,且需要一定的保温保湿措施。沙床大小以育苗的多少而定,一般苗床下层铺8～10厘米厚的小石
Hongye Li is a common plant in the landscape of colorful plants, has a strong ornamental value, the general use of grafting propagation, battens breeding and cutting propagation second. In recent years, it has been found in production practice that seedlings in sand storage are also good breeding methods for red leaf plum. Sand seedlings from the cutting seedlings developed, with high practicability and feasibility, and low cost, high efficiency, it is worth in the production of the promotion and application. First, seedlings of sand seedlings 1. Seedbed construction. Sand bed should be built in a well-ventilated, high-lying, convenient irrigation sprinkler, and the need for some thermal insulation moisture measures. The size of the sand bed depends on the number of nursery, the general shop under the bed 8 to 10 cm thick stone
