Cutting method of purple leaf plum:

Seedbed preparation:

the cutting time of purple leaf plum is from the time when the trees fall leaves in autumn to before the ground freezes. Before cutting, the seedbed needs to be prepared in advance. Fertile plots with sunny ventilation should be selected as seedbeds, the land should be turned over deeply, enough fertilizer should be applied, and then it should be sorted and leveled

Prepare cuttings:

the cuttings are made from the branches of Prunus pumila, which are strong and born in the same year, and cut into branches with a length of about 10 ~ 15 cm. The lower end of the cuttings needs to be cut into an oblique horseshoe shape, so that the rooting surface will be larger, which is conducive to rooting. The upper end is cut flat and the cutting section is reduced, which can reduce the water loss of cuttings. Bind the cuttings into a bundle of 100 ~ 150, then soak them in 50ppm indole butyric acid solution for 24 hours, and take them out for standby

Cutting of purple leaf plum:

first fill the whole seedbed with enough water, and then cut after the water completely seeps into the soil. The depth of cutting is two-thirds of that of cuttings and one-third of that of exposed cuttings. Generally, the plant spacing is about 3cm and the row spacing is about 5cm. After the whole bed is full, sprinkle a thin layer of fine soil on the bed surface to prevent the surface from drying and cracking and water evaporation

Frame covering:

use thin bamboo poles to cross each other, build a simple small arch shed on the cutted seedling bed, and bind the intersection of bamboo poles tightly with ropes to prevent them from shaking left and right. Once the arch is erected, it shall be immediately covered with plastic film for heat preservation and moisture retention

Seedling management of purple leaf plum:

1. Ventilation, watering and weeding: from cutting to warm spring next year, the cuttings have basically taken root, but the root system is still fragile and needs careful management and protection. By mid March, the climate is stable, so it is necessary to uncover the plastic film at both ends of the seedbed early and cover it late for ventilation and seedling refining. When the climate is stable and warm, remove the film completely, remove weeds in time and water regularly 2. In the middle of April, remove the greenhouse film, spray 0.5% urea solution on the leaf surface to enhance its growth, then apply nitrogen, phosphorus and potassium compound fertilizer every 45 days or so, water according to the soil, stop fertilization before the end of August, and transplant it into the nursery for cultivation in the next spring
