Perkins has been favored by landscape designers because of its dense flowers, bright colors, long flowering period, and extensive management. The following three methods are commonly used for the propagation of Pergamon in perennial roots:
First, the ramets breeding: This method is simple, rapid survival, but not suitable for mass reproduction. Time: In early spring or autumn. The rooting ability of the roots of Pheromanthus perforatum is strong, and the characteristics of the roots and shoots are easily developed during the growth process. The sprouting plants around the mother plants are excavated and planted. Sprout strains should have complete root systems as far as possible in order to increase the survival rate.
Second, bead propagation: time: in the spring, summer and autumn.
1. Bound layer of soil: The foundation of the soil is made into a bread-like shape, so that it can be separated and planted after rooting.
2. Ordinary pressing: The first and second year branches close to the ground will be buried in the ground and the upper part of the branches will be exposed on the ground. When the layers are pressed, the bark of some of the branches embedded in the soil will be cut in advance (returning nourishment, which will facilitate rooting. After 30 days of rooting, it can be planted separately from the mother plant.
Third, the cutting propagation: Perennial root cuttings can be inserted, stem insertion and leaf insertion.
1. Root cutting: In spring and autumn, combined with ramets planting, some roots are cut into small sections about 30 centimeters long. They are buried in plain sand and keep the soil moist at 15 to 20 degrees for about 30 days. Can sprout new shoots. 2. Stalk insertion: In spring, summer and autumn, it usually takes place after flowering. Stem inserts are suitable for mass production, combined with pruning heads to take full-grown shoots, cut 3 to 5 cm long cuttings, insert in clean sterile sand, spacing of 2 to 3 cm, and keeping soil moisture, 30 days or so can take root. Pay attention to spraying 800 to 1000 times 50% carbendazim solution one to two times in summer to prevent the cuttings from rot.
3. Leaf plug: Take leaves with axillary buds in the summer (leaves left 1/2 or so), with 2 cm long stems, inserted in a clean sterile sand, pay attention to shade, and keep the soil moist, about 30 days root.
