Cultivation method of bending trunk type dwarf crape myrtle

Abstract

The invention provides a cultivation method of bending trunk type dwarf crape myrtle. The cultivation method of the bending trunk type dwarf crape myrtle includes: adopting a multiple trunk twisting method to thicken a main trunk in spring, selecting 2-3 varieties of crape myrtle lateral buds different in flower color and plump in middle, and cutting bark of rootstock into a T shape; inserting bud pieces, wrapping Wanan kaolin around the bud pieces and fastening the bud pieces with a plastic film belt for bud grafting, unbinding the plastic film belt after grafting buds survive, and cutting off portions of the grafting buds, above the rootstock; stretching scions on a portion one third the stem height of a tree trunk after the scions start to grow, and leaving a left outside skeleton branch on a corner; leaving a second skeleton branch on a portion two thirds the stem height of the main trunk, and enabling the second skeleton branch to grow towards the low right outside; performing pinching at the top of the main truck, and leaving two skeleton branches on the left side and the right side of the main truck; applying multiple effect filing once in a germination stage; duly applying phosphate fertilizer and potash fertilizer to the crape myrtle and slightly applying nitrogenous fertilizer in May and June; cutting tips two thirds or one half the length of a skeleton main branch in April, and cutting stubbed flowers and young fruits along with 3-4 leaf burls after flowers fall; performing trimming and curling, and manufacturing small or mini bending trunk type bonsai after 2-3 years of time.

Description

technical field [0001] The invention relates to a method for cultivating plants, in particular to a method for cultivating bent dry dwarf crape myrtle. Background technique [0002] The root system of dwarf crape myrtle is well developed, and its flower color is bright, and it can bloom in large quantities in hot summer. Moreover, the plant shape is short and compact, which can be planted in the ground or potted, and has a wide range of landscaping uses. It can be used as planting tree species for highways, railways, embankments, green belts on river slopes, isolation belts, slope protection, and sand-sealing vegetation. It can also be used for greening and beautifying hedges and color block planting tree species in mining areas, residential areas, and scenic spots. It is also the preferred flowering shrub tree species for greening in large and medium-sized cities and industrial and mining areas where harmful gases exceed the standard. Although it is widely used in garden...

AI Technical Summary

Problems solved by technology

[0003] The crape myrtle cultivated by the traditional method of dwarfing the crape myrtle has a single color, and the crape myrtle stem is straight and difficult to shape during the cultivation process. The branches of the crape myrtle are slender and numerous, which is not suitable for excessive distortion. In addition, the crape myrtle likes fat and consumes more nutrients for flowering If there is a lack of fertilizer, it will lead to thin and weak branches of Lagerstroemia indica, yellow leaves, weak growth of the whole plant, little or no flowering, but excessive fertilization of Lagerstroemia indica will easily cause excessive growth of branches and leaves, and affect the dwarfing effect

Therefore, the traditional cultivation method of dwarf crape myrtle is likely to cause disadvantages such as poor shape of crape myrtle or poor dwarfing effect, and the traditional grafting method of crape myrtle also has problems such as low survival rate and slow healing.
