When are Japanese cherry blossoms cut?

It can be carried out in April-July, and the experimental records are as follows: As can be seen from the above table, the survival rate of cherry cuttings is the highest in full bloom, so the cuttings are at the peak of physiological activities and are easy to take root. Cutting was cut on April 28th, and seedling emergence was not delayed after transplanting on June 28th. Five days later, a new bud of 0.5 cm grew. After four years of cultivation, the tree was full of flowers.

Selection of cuttings Cut branches with a length of 15 cm from the robust mother tree, with annual branches at the upper end and annual branches at the lower end. The leaves on the new shoots can make nutrition, the annual branches are lignified, and the cuttings are easy to survive. Experiments show that most cuttings of 3-6 years old rot and die. It can be seen that the survival rate of cuttings is related to age. The older the branches, the weaker their physiological functions, and the more difficult it is to survive.

Treatment of cutting before cutting, remove some leaves that have infiltrated vermiculite and keep the upper leaves. Quickly dip the cuttings with 1000ppm NAA. That is, insert 1000 ppm NAA solution 2-3 cm away from the base of the cuttings, then immediately take out the cuttings and dip them in.
