Method for quickly shaping high-stem grafted bougainvillea glabra in lollipop shape

Abstract

The invention belongs to the technical field of plant shaping and discloses a method for quickly shaping high-stem grafted bougainvillea glabra in a lollipop shape. The method includes: subjecting small-leaf purple bougainvillea glabra to long-shoot cutting cultivation to obtain a high-stem bougainvillea glabra stock potted plant; when thickness of a top grafting reserved branch 30cm above reaches0.8-1.2cm, selecting a high-branch-erectness bougainvillea glabra variety in another color as a scion, grafting on the high-stem bougainvillea glabra potted plant stock by cleft grafting, topping once by keeping three leaves every time a sprout of the scion grows five leaves, and performing repeated topping on each lateral branch to obtain a basic frame by cultivation; by repeated directional topping, cultivating a crown in an externally-dense internally-hollow spherical or trapezoidal lollipop shape. The method for quick cultivation in a cultivation process of 180-210 days is simple and convenient to operate, short in production period and beneficial to large-scale popularization, industrial development of bougainvillea glabra can be effectively promoted, and market competitiveness can be improved.

Description

technical field [0001] The invention belongs to the technical field of combination of cuttings and grafting modeling of tropical flowers and plants, and in particular relates to a rapid prototyping method for bougainvillea lollipop modeling with tall stem grafting. Background technique [0002] Bougainvillea is a plant of the genus Bougainvillea in the family Mirabilis. It is native to Brazil and has been introduced to my country for more than 150 years. It is the main flower viewing plant in the south. It is currently the provincial flower of Hainan Province and the city flower of more than 20 cities. It is widely used, such as in roads, street gardens, three-dimensional greening of overpasses, courtyards, families, etc. At present, the common application methods of bougainvillea are mainly sheet plants and potted plants, but there are few varieties that can be used, and there is a shortage of shaped ones due to the long production cycle, so most of the products are simple...

AI Technical Summary

Problems solved by technology

Because bougainvillea is a climbing shrub with a large amount of side branch germination, its growth needs to be supported and only a single stalk is often pruned to form a tall stalk shape, such as lollipops and mushroom umbrellas. Bougainvillea potted plants require a long time for cultivation, and it takes 2 years to cultivate finished products after the cuttings survive potted plants, which rarely appear in the market, which also affects the wider application of bougainvillea.
