[propagation of crape myrtle] how to reproduce wisteria

Crape myrtle is a kind of tree species distributed in the Yangtze River Basin, which is also cultivated in South China, North China and Northwest China, and has strong adaptability. Crape myrtle is a strange species of trees. its body is so smooth that even monkeys can't climb it. When the tree grows up, the trunk bark falls, smooth and skinless. If people gently touch the tree, it will shake its branches and leaves and tremble all over. So people also call it "ticklish tree". Let's take a look at the breeding method of crape myrtle.

I. Propagation of crape myrtle

Introduction to the propagation methods of crape myrtle tree cuttings: hardwood cuttings and tender cuttings.

The hardwood cuttings are usually carried out before the branches germinate from mid-late March to early April. Select sturdy annual branches, cut them into 1-5cm-long cuttings, insert them into loose and well-drained sandy soil seedbeds, and cut deep enough to expose the uppermost bud of the cuttings. After insertion, pour through water and cover with plastic film to keep moisture and heat preservation. When the seedling grows to 15m ~ 20m, the film can be lifted, changed into a shade net, and watered at the right time, and the branches can grow to about 60m ~ 80m in the same year.

The shoot cuttings were carried out from July to August, when the new shoots grew vigorously and had the most vitality. Select semi-lignified branches and cut them into cuttings with 8~lOcm length, leaving 3 leaves at the top. The insertion depth is 3~4cm. After inserting, pour water through, and build a shade shed to shade, generally take root in about 20 days, remove the film, retain the shade net, and then timely watering, the branches can grow to about 60 million meters in that year, and the survival rate is very good.

Second, the culture method of crape myrtle:

Planting. Crape myrtle is a positive tree species, when planting to choose a sunny environment, the soil is required to be moist and fertile, and has good drainage. The transplanting time of crape myrtle is from March to early April, with Ching Ming Festival as the best, followed by autumn. When transplanting, the plant should take the soil, leave the trunk 100 to 120 square meters to cut off the upper part, and wait for the new shoots to grow, leaving 3 or 4 main branches with the most suitable angle to let it blossom.

Light watering: crape myrtle is a light-loving plant, so it must be placed in outdoor sunshine during the growing season. At the same time, crape myrtle requires a lot of water during the growing season, so it needs to keep the soil moist. Keep the basin soil moist in spring and east, and water each in the morning and evening in summer and autumn. In case of high temperature, you can increase the frequency of watering.

Regular fertilization: crape myrtle is a fertilizer-loving plant. Lack of fertilizer in potted crape myrtle will lead to weak branches and yellow color, resulting in weak plant growth, little or no flowering, but excessive fertilization will lead to excessive growth of branches and leaves. More fertilizer can be applied in the vigorous growth season in spring and summer, less fertilizer in autumn, no fertilization in dormancy in winter, and no fertilization in rainy season and hot noon in summer.

Third, the method of making crape myrtle bonsai

Crape myrtle can be propagated by sowing or by ramet and cuttings. Sowing and propagation are usually carried out in March of each year, when the seedlings can reach as high as 30ml / 40m. Cuttage propagation is a common method for making miniature or miniature crape myrtle bonsai. It usually blossoms for 2-3 years and forms quickly. The trunk of crape myrtle is straight and brittle, and the depth of the cuttings is generally 4 mi 5 cm, which is not as deep as that of other seedlings. After insertion, you should pay attention to watering and keep the matrix moist, but do not accumulate water. In the year when crape myrtle was planted, after falling leaves, the trunk was completely cut off from the surface of the soil layer. In the second year, pay attention to fertilizer and water management. After crape myrtle leaves fall in November, the trunk will be cut off from the ground at 2m / m. Through pruning, the disadvantage that crape myrtle is straight and not easy to shape can be overcome.

Crape myrtle enters the shade shed management after potting, and can be restored to life in 15 days. Crape myrtle stem is finer, so the bonsai made by small seedlings adopt more dry twisting method to thicken the trunk. That is, the use of crape myrtle rhizosphere sprouting branches, one by one along the trunk into a spiral winding, after 1 Murray 2 years, the branches and trunk can heal together, become a whole, and appear old and simple. If the seedlings of different colors are planted together in a hole, the base is tied together to make the trunk wind around each other, the same effect can be formed after 3 years. The branches of crape myrtle are long and slender, which are not suitable for excessive distortion. Generally, pruning and shaping can be used to make them more beautiful.

If it is used as a family interior decoration, then wisteria flowers are mostly potted and decorated. Placed in balconies, corridors and other places. For potted wisteria, its fertilizer and moisture can be uniformly controlled, so it can indirectly control the climbing or growth conditions. And can form the possibility of blooming in the four seasons, wisteria flowers can make specimens or plastic products of wisteria can decorate the walls, cabinets, doors and windows of home decoration, with a good effect.
