Method for regulating flowering of bougainvillea speetabilis

Abstract

The invention relates to the technical field of flower cultivation, in particular to a method for regulating flowering of bougainvillea speetabilis. According to the technical scheme, the method for regulating flowering of bougainvillea speetabilis comprises the steps of pruning, soil loosening and fertilization, girdling, spraying of a flower-promoting nutrient solution and flowering stage treatment, and the nutrient solution used in the step of spraying of the flower-promoting nutrient solution is an aqueous solution containing 1-1.5 mg / L of triacontanol, 1-1.5 mg / L of monopotassium phosphate, 1-2 g / L of diaminoferric xanthohumate, and 1-2 g / L of saccharose. When the technology is used for regulating flowering of bougainvillea speetabilis, the flowering time can be accurately controlled,and the effects of a consistent flowering stage, seasonal flowering and required flowering are achieved. The flowering number can be increased, the time from a squaring stage to a full-blossom stageis shortened, and the flowering stage is prolonged; and the whole process is regulated and controlled, so that the bougainvillea speetabilis can be kept robust and attractive, the phenomenon of excessive senility caused by massive flowering is avoided, and long-term maintenance of bougainvillea speetabilis landscape is facilitated.

Description

technical field [0001] The invention relates to the technical field of flower cultivation, in particular to a method for regulating and controlling the blooming of bougainvillea. Background technique [0002] Bougainvillea is a vine-like shrub of the family Mirabilis Bougainvillea, widely distributed in tropical and subtropical regions of the world. In my country, bougainvilleas are mostly distributed in southern regions such as Hainan, Guangxi, Guangdong, Fujian, Yunnan, and Sichuan. Bougainvillea has bright colors, long-lasting flowering period, and can bloom all year round, so it is very popular among people. At present, bougainvillea is widely used, and its beautiful figure can be seen everywhere in park green spaces, road greening, overpass greening, etc. It plays an important role in beautifying cities, improving the environment, and garden city construction.

AI Technical Summary

Problems solved by technology

[0003] In the cultivated species of Bougainvillea, there are often phenomena such as only growing leaves but not blooming, scattered plant types, and inconsistent flowering periods, which greatly affect the appearance and ornamental effect. With the gradual promotion of the application of Bougainvillea, it is very important to control the flowering of Bougainvillea

In the prior art, the common technical means for flower regulation of bougainvillea include shading to induce flowers, frequent pruning to promote flowers, water control to promote flowers and hormones to induce flowers, etc., but these methods have certain limitations, for example: shading to induce flowers requires shading Equipment, which limits large-scale application; frequent pruning to promote flowering requires a lot of work, and the effect of promoting flowering is not good, generally not used alone; water control to promote flowering combined with pruning and fertilization has a significant effect, but the application field is limited to potted bougainvillea The application of hormones to attract flowers is convenient, the action time is long, and the effect is remarkable, but the application amount of bougainvillea is different for different varieties and regions, and it needs to be studied separately for each variety. Some hormones are also harmful to the environment. Currently, they are used in urban public green spaces. This method is generally not used in bridge greening

[0004] According to the control method of Bougainvillea in the prior art, there are disadvantages such as high technical difficulty, unsuitable for large-scale operation, complicated operation, high cost, and narrow application range.
