Embodiment 1

[0024] A kind of cultivating method that makes Bougainvillea bougainvillea bloom twice after the flowering period, comprising the following steps:

[0025] (1) In the bougainvillea planting pot, after it reaches the flowering period in June, excavate the soil along the outside of the bougainvillea canopy drip line to remove the redundant old roots and broken roots, and cut the broken roots with scissors or blades to make the cross section smooth;

[0026] (2) Spraying concentration of 300ppm naphthalene acetic acid to the bougainvillea after root removal, to accelerate the withering of the blooming flowers, then pruning and topping its top, destroying its top advantage, and removing the flower buds that exist at the top, and promoting side growth. Differentiation of buds and buds to facilitate the subsequent secondary flowering;

[0027] (3) Control the water during the treatment in step (2), and the water control time is 2 to 3 weeks, and stop fertilizing when the roots are ...

Abstract

The invention discloses a cultivation method for secondary blooming of bougainvillea speetabilis after the blooming period. The cultivation method comprises the following steps: (1) after bougainvillea speetabilis blooms in June, digging soil and cutting roots along the outer side of a canopy water drip; (2) spraying a plant growth regulator to wither all bloomed flowers, pruning and pinching branches at the top ends of the flowers, and removing unbloomed flower buds at the top ends to promote flower bud differentiation; (3) controlling water for 2-3 weeks while pruning the top end, and stopping fertilizing, so that the epidermis of the current-year branches is wrinkled and the branches and leaves are withered due to water shortage; and (4) after 10-12 days of treatment in the step (3), spraying a concentration plant growth regulator to the bougainvillea speetabilis every 10-15 days, after new flower buds are preliminarily formed, starting to apply fertilizer and water, and applying an auxiliary regulator once every 3-5 days until the flower buds bloom. The bougainvillea speetabilis can bloom again after the blooming period, and the blooming period is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of gardens, in particular to a method for cultivating bougainvillea to bloom twice after flowering. Background technique [0002] Bougainvillea, also known as bougainvillea (scientific name: Bougainvillea spectabilis Willd.), belongs to the family Mirabilis, and bougainvillea is a woody vine-like shrub with curved thorns on the stem and dense hairs. Single leaves alternate, ovate entire, thickly tomentose, apex round and blunt. The flowers are very small, yellow-green, and three are gathered in three red bracts. The outer red bracts are large and beautiful, including bright red, orange yellow, purple red, milky white, etc. They are mistaken for petals because of their shape. leaves, so it is called bougainvillea. The flowering period can be from November to June of the following year. In winter and spring, the colorful bracts appear, giving people a bold and warm feeling, so it is also named He Chunhong. ...
