Cutting propagation method for koelreuteria paniculata

Abstract

The invention discloses a cutting propagation method for koelreuteria paniculata. The cutting propagation method comprises the following steps of collecting cutting wood; shearing cutting slips; wintering the cutting slips; cutting in soil. According to the method provided by the invention, a rooting rate of the cutting slips of the koelreuteria paniculata is enabled to reach 95 percent or above; compared with the prior art, the cutting propagation method disclosed by the invention has the advantage that the breeding efficiency is greatly improved.

Description

technical field [0001] The invention relates to a cutting propagation method of eucalyptus. Background technique [0002] Luan tree (Koelreuteria paniculata), alias: Mu Luan, Luan Hua, etc., is a plant of Sapindaceae and the genus Luan. It is a deciduous tree or shrub; the bark is thick, gray-brown to gray-black, longitudinally cracked when old; the lenticels are small, gray to dark in color; the branchlets have warts, and the leaf shafts and petioles are covered with wrinkled pubescence or hairless. In the prior art, the seedlings of eucalyptus all adopt seeds to sow and raise seedlings. Because the seed coats of eucalyptus seeds are hard and difficult to permeate, if they are not managed by accelerating germination, they often do not germinate or the germination rate is very low in the second year of spring sowing. The germination rate is low, and the amount of seeds should be large, generally 50-100g per square meter. The sowing land requires loose and air-permeable so...
