Problems solved by technology

The grafting survival rate of safflower crape myrtle under the current technology is low, only about 15%, and the split grafting method is mainly used
At the same time, after grafting of safflower and crape myrtle, it takes 2-3 months to determine whether it survives, and the grafting period is longer
[0003] Chinese Patent Publication No. CN103704028B, published on September 09, 2015, this technical solution relates to a grafting method for cultivating tall stem seedlings by grafting short branches of Jin Wei, which is characterized in that: the buds of Lagerstroemia crape myrtle 'Powder Crystal' are used

Embodiment 1

[0016] Embodiment 1: a kind of grafting method of crape myrtle

[0017] 1. Collect a high-quality tender bud in the 2 to 4 bud points at the front end of the grafted variety ear branch as the scion. This tender shoot is an autumn bud, and the length of the scion is 3-5cm. The selected scion must be grafted with the rootstock within five days;

[0018] 2. Select the crape myrtle safflower that has grown for more than two years as the rootstock. The crape myrtle safflower is selected from the American red daughter crape myrtle tree variety, cut off at a height of 10-15cm from the rootstock, and each crape myrtle rootstock is grafted with a tender bud point Among them, the crape myrtle safflower as the rootstock is best grown for two years, and there is no requirement for the size of the rootstock;

[0019] 3. Use the docking method. From early March to mid-April in spring, when the temperature is 18-30°C and the humidity is 45-85%, the selected scion and the rootstock are closel...

Abstract

The invention discloses a grafting method for purple-red lagerstroemia indica. The grafting method comprises the following steps: 1) collecting tender shoot with 2-4 buds in front of ear shoot as scions, and cutting the scions to be 3-5cm; 2) selecting the purple-red lagerstroemia indica which grows for more than years as stock, and cutting off the stock at a position of 10-15cm from the ground; 3) inarching: under weather with a temperature of 18-30 DEG C and humidity of 45-85%, tightly fitting the scions with the stock skin to skin, binding and tightly holding the scions and the stock by use of an adhesive tape or a packaging rope, and then, sealing by use of a special plastic bag for grafting; and 4) observing whether the grafting is successful or not within 30-40 days, and dismounting the special plastic bag for grafting when cotyledons are grown out. The grafting method has the advantages that: the grafting method is adopted for grafting under proper temperature and humidity; the grafting survival rate of the purple-red lagerstroemia indica is increased to 80% from 15%; and people can know whether the grafting is successful or not about 35 days after the grafting, so that the grafting period is shortened. Meanwhile, the grafting method is simple to operate, and easy to popularize.

Description

technical field [0001] The invention relates to a plant grafting method, in particular to a crape myrtle grafting method. Background technique [0002] Lagerstroemia safflower, deciduous shrub or small tree, shrub-like, 3-7 meters high; bark is easy to fall off, trunk is smooth. The older the trunk, the more radiant it is, and the whole plant trembles slightly when you touch it with your hands, so it is also called itchy tree.
