Abstract

The invention relates to a fast propagation method for dendrocnide meyeniana cuttage. The fast propagation method includes the steps that firstly, cutting selecting and disinfecting are conducted; secondly, branches of disinfected dendrocnide meyeniana are processed; thirdly, the processed branches are arranged in a matrix of a seedbed in a cuttage mode; fourthly, maintaining and managing are conducted after cuttage. The dendrocnide meyeniana grown in a cuttage mode through the fast propagation method roots rapidly, the cuttage seedling emergency rate is high, production cost is low, the technology is simple, and a research basis is provided for large-scale development and utilization of the dendrocnide meyeniana.

Description

technical field [0001] The invention relates to a rapid propagation method for biting dog cutting culture, and belongs to the technical field of plants. Background technique [0002] Biting dog, Urticaceae, Dendrocnide meyeniana , an evergreen tree, native to Taiwan, produced in low-altitude forests throughout the island. This area grows in the forest at the foot of the mountain, the number is large, and the distribution area is sporadic. Bark rough, with obvious lenticels. The long stalks of the leaves can reach 15 cm, and the branches are clustered. The leaf shape is oval or obovate, with entire or wavy edges, and the length can reach 40 cm. The flowers are dioecious, the inflorescence is a cyme, axillary, the inflorescence branch is light reddish green, and the female flower has a white, translucent receptacle. This species is a poisonous plant included in the Chinese Plant Atlas Database. The sting is unbearable. The current breeding method is mainly natural breedin...
