Embodiment 1
[0028] 1. Collection of cuttings: On March 16, a robust, pest-free, 30-year-old pomegranate tree was collected, and the 20-year-old branches on it were collected as cuttings, and 38 cuttings were collected, and the lower cut was cut into a horse ear shape , the cuttage branches with an average length of 30cm and an average diameter of 6.5cm.
[0029] 2. Seedbed establishment and substrate preparation: establish a seedbed 50 cm above the ground as a cutting propagation area, mix peat: sand in a ratio of 1:2 by volume to form a substrate, sprinkle it into the seedbed after stirring, and make the substrate The thickness is 45cm, and the substrate is sterilized with 800 times potassium permanganate solution 24 hours before cutting;
[0030] 3. Treatment of cuttings: Soak the cut cuttings in water for 36 hours, then use the special rooting powder solution with a concentration of 1500ppm produced by Shanghai Jiafeng Horticultural Supplies Co., Ltd., and soak for 1.5 minutes;

Abstract
The invention discloses a pomegranate old branch cuttage and rapid propagation method. According to the method, pomegranate tress of 25-35 years are selected, old branches,15-25 years old, on the pomegranate tress are collected to serve as cuttings, the cuttings are soaked with clean water and then soaked with a special-effect rooting powder solution, and the cuttings are placed into grass carbon in a cuttage mode in late March every year; sand is mixed into a medium according to the volume ratio of 1-1.5:2-3, a mulching film covers the surface of the mixture, cuts in the cuttings are exposed out of the mulching film and are wrapped for moisture retention, and a seedling management stage starts. The rooting rate of pomegranate old branch cuttings propagated in the method is as high as 95%, and the method is easy to operate, short in period, low in cost and quick in effect, solves the technical problems of pomegranate old branch cuttage and propagation and lays a foundation for manufacturing thick, strong and unadorned Taoist potted landscapes.
Description
technical field [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a method for rapid propagation of pomegranate old branch cuttings.
