preparation example Construction

[0030] In the present invention, the B9 solution is preferably sprayed on hydrangea thinning branches in the process of continuing cultivation, preferably once every 4 to 6 days, more preferably once every 5 days; the total number of times of spraying is preferably 3 to 5 times, more preferably 4 times; the preparation method of the B9 solution preferably includes: mixing according to the mass of B9 and the volume ratio of water is preferably 1g:400~1000mL, more preferably 1g:800mL, to obtain the B9 solution ; The spray dose of the B9 solution is preferably 25mL / m 2 . The invention sprays the B9 solution on the thinning hydrangea, not only can effectively inhibit the vegetative growth of the hydrangea plant, increase the stem diameter, and make the plant more compact, but also can advance the flowering period of the hydrangea without causing deformity of branches and buds.

[0031] The present invention has no special limitation on the source of B9, and conventional commercia...

Abstract

The invention provides a cultivation method for regulating and controlling the hydrangea flowering period, and belongs to the technical field of plant cultivation, and the cultivation method comprisesthe step of placing hydrangea plants at the temperature of-8 DEG C to 8 DEG C for 30-45 days. Experimental results show that by adopting the cultivation method for regulating and controlling the hydrangea flowering period, the blooming rate of the hydrangea reaches up to 100%, vegetative growth of the hydrangea can be effectively inhibited, the blooming period is advanced by 2-3 days, the blooming branch internode spacing is reduced by 20.5%, stem diameter is increased, and plant type is more compact without causing branch bud deformity.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a cultivation method for regulating and controlling the flowering period of hydrangeas. Background technique [0002] Hydrangea is a plant of the saxifrage family Hydrangea, also known as Hydrangea, Fentuanhua, Hydrangea, Seven Variations, and Western Hydrangea. It is native to the south of the middle and lower reaches of the Yangtze River in mainland China and Honshu, Japan. Hydrangea has plump, large and beautiful flowers. Its color can be red or blue, which is pleasing to the eye and refreshes the mind. It is a common potted ornamental flower and tree, and it is another mainstream flower variety after roses, carnations, and lilies. Hydrangea likes a warm, humid and semi-shady environment. The suitable temperature for growth of hydrangea is 18-28°C. The natural flowering period of hydrangea is generally from June to October. With the continuous improvemen...
