Grafting method of bauhinia blakeana

Abstract

The invention relates to the technical field of landscape plant grafting, and discloses a grafting method of bauhinia blakeana. The grafting method of the bauhinia blakeana comprises the following steps that cercis gigantea with the diameter of 6 cm or above is selected to be subjected truncating, and a truncating point is taken as a grafting point; an old cercis chinensis branch is selected as agrafting branch to be subjected to grafting at the grafting point of the cercis gigantea; the grafting point and the grafting branch are sleeved with a sealed bag; after the grafted branch sprouts, the bag is cut open for ventilation; and after the plastic bag is unfastened, pesticide is sprayed in 10-20 days to prevent aphids. According to the method, after grafting is completed, the bauhinia blakeana has the characteristics of red flower color, dense petals and long flowering phase, is more beautiful than cercis gigantea in tree shape and long in growth period, can be more applied to streettrees, parks, communities, villas and the like, and is wide in application range.

Description

technical field [0001] The invention relates to the technical field of landscape plant grafting, in particular to a method for grafting safflower bauhinia. Background technique [0002] Bauhinia Bauhinia, also known as Bauhinia safflower, is a deciduous tree; the bark is dark brown, almost smooth; the young parts are often covered with gray pubescent hairs; the branches are broad, hard and slightly zigzag, glabrous. Leaves are nearly leathery, broadly ovate to nearly round, often wider than long, apex 2-lobed up to 1 / 3 of leaf length, lobes broad, blunt or round, glabrous on both sides or slightly gray pubescent below. Raceme lateral or terminal, extremely shortened, more or less corymbose, few flowers, covered with gray pubescence; flowers large, nearly sessile; buds spindle-shaped; calyx spathe-shaped, pubescent ; Petals obovate or oblanceolate, 4-5 cm long, petal-stalked, purple or light red, mixed with yellow-green and dark purple markings. Pods ribbon-shaped, flat; se...

Problems solved by technology

[0004] But no matter whether it is Bauhinia safflower or Bauhinia safflower, there are shortcomings such as not bright enough flower color, not red enough, dense petals, and not beautiful tree shape. Therefore, there is an urgent need for a grafting method of Bauhinia safflower to improve the above problems.
