Problems solved by technology

Although crape myrtle blooms prosperously and has a very high fruiting rate, when the capsules mature and crack, the winged seeds can fall all over the ground, but the naturally scattered seeds can hardly germinate into seedlings, and the germination rate of artificially planted seeds is also low, so crape myrtle is mostly The method of growing seedlings by cuttings
Although the current traditional method of cutting seedlings has simple processing steps, the rooting rate of the cuttings is low, only about 86%, and the rooting period is long. Generally, it takes about 20 days to take root in large quantities, and the growth rate of the seedlings is relatively slow. Finally, the branch length can reach about 70cm, and the cutting effect is not very ideal.

Abstract

The invention discloses a cutting breeding method for crape myrtle. The cutting breeding method for the crape myrtle comprises the following steps: (1) selecting half-lignified current-year branches, cutting to be cuttings of which the length is 7-9 cm, keeping 2-3 leaves at the upper part of each branch; (2) soaking the cuttings in soaking solution for 12-14 hours, and placing the cuttings in a sealed container in which the concentration of carbon dioxide is 800-820 ppm, and taking out after 20-25 min; and (3) taking out the cuttings in the container, and placing in 10-14 DEG C of the environment for 40-60 min, and inserting in a seeding matrix, wherein the inserting depth is 3-4 cm. The method is used so that the rooting percentage of the crape myrtle cuttings is higher and the growth rate of the cuttings is faster, the seedling period is shorten, the utilization ratio of the land is improved, the bred crape myrtle cuttings has good stress resistance and higher survival rate, and the method is suitable for large-scale promotion and planting.

Description

technical field [0001] The invention belongs to the field of flower planting, and in particular relates to a cutting propagation method of crape myrtle. Background technique [0002] Lagerstroemia genus is a deciduous tree belonging to the Lagerstroemiaceae family, native to my country, Asia and northern Australia. The flowers are white, pink, red, purple and other colors, the flower diameter is 3-6cm, the calyx has no edges, and there are many stamens, and the outer 6 are born on the calyx, which is stronger and longer than the rest. It is distributed in all provinces in the Yangtze River Basin of my country. Introduced to Hebei, Beijing, Xi'an, Dalian and other places for open field cultivation, there is basically no freezing damage. It is the most widely cultivated crape myrtle species in my country and the world, with more than 40 varieties. Lagerstroemia crape myrtle has a very long flowering period from June to September, and has a very high ornamental value. It blooms...
