Abstract

The invention discloses a softwood cutting propagation method for liquidambar styraciflua. The softwood cutting propagation method comprises the following steps of (1) cutting time; (2) preparing a rooting agent; (3) preparing a cutting medium; (4) implementing cutting shoot treatment and cutting; and (5) implementing after-cutting management and transplanting. The softwood cutting propagation method for the liquidambar styraciflua can achieve a cutting rooting rate greater than 83.5%. The method is simple and convenient to implement, and has the advantages that cost is low, operation is simple and easily implemented, popularization and application are easy, and the like; and the method has important application and popularization values on liquidambar styraciflua seedling production.

Description

technical field [0001] The invention relates to a method for asexual propagation of plants, in particular to a method for cutting and propagating softgrows of sweetgum sweetgum. Background technique [0002] Liquidambar sec tyraciflua is a deciduous tree of the genus Acer in the family Aceraceae, native to North America. This species is suitable for introduction to the south of the Yangtze River Basin in my country. Its leaves are dark green in spring and summer, and turn yellow, purple or red in autumn. The leaves fall late. In some areas, the leaves hang on the trees until February of the next year, which is very good. garden ornamental trees. [0003] At present, the North American sweetgum is mainly propagated by seeds, and the seeds need to be imported and purchased from North America, and the cost of raising seedlings is relatively high. The seedlings propagated by seeds are quite different and cannot maintain the excellent characteristics of the female parent. The e...
