Grafting method for purple-red lagerstroemia indica

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. Likes light, slightly shade-tolerant; likes warm climate, not strong cold resistance; likes fertile, moist and well-drained calcareous soil, drought-tolerant, afraid of waterlogging. The trunk of the crape myrtle tree is smooth and clean, and the flowers are gorgeous; when it blooms, it is the season of few flowers in summer and autumn, and the flowering period is extremely long, from June to September, so it is called "hundred-day red" and "midsummer green cover eyes". , This bounty is full of praise" is a good bonsai material for viewing flowers, v...

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 to become new The cultivar 'Jinwei' is used as a scion to cultivate the high-stalk seedlings of 'Jinwei'. On the basis of retaining the excellent ornamental characteristics of the new variety 'Jinwei', the high-stalk finished seedlings of 'Jinwei' can be quickly cultivated, shortening the Seedling raising cycle; steps such as cutting the anvil, cutting the scion and splicing are quick and easy to operate, and the survival rate can reach 84-90%. It is obvious that this technical solution has the problem of grafting wound contamination

However, chemical treatment will cause certain pollution to the grafted
