Description

Technical Field

[0001] The invention relates to the technical field of flowering period regulation, and in particular to a method for regulating the flowering period of azalea. Background Art

[0002] The tree of azalea is tall, with luxuriant branches and leaves, elegant posture, strong germination ability, and tolerance to pruning; the flowers are large and bright, the color is eye-catching bright red, and the flowering period is long; the leaves are small and dense, oval, and show different shades of leaf color at different growth stages, such as light green, emerald green, dark green, and even green gradually turning red; the root stump is winding and ornamental. In addition to the basic aesthetic value of appearance, azalea also has intrinsic spiritual value. People use the scene of azaleas all over the mountains to metaphor the spirit of perseverance, which has given birth to many literary and audio-visual works.

[0003] The natural flowering period of azalea is from March to June every year. Specifically, the flowering time of azalea in the southern region is generally in spring, approximately between March and May, and the flowering time of azalea in the northern region may be delayed, generally between April and June. The overall flowering period lasts about 1 to 2 months, and the flowering period is short and relatively concentrated. Therefore, in order to extend the viewing period, it is necessary to regulate the flowering period of azalea. For example, a Chinese patent (CN101243747A) discloses a method for regulating the flowering period of alpine azalea in winter. First, select plants of appropriate age from alpine azalea varieties that are easy to force to bloom, put them in an environment below 10°C, store them for 2-3 months, and force them to dormant; then gradually increase the ambient temperature of the alpine azalea from 10°C to about 20°C, and supplement the light for the alpine azalea during the same period, with daily light exposure greater than or equal to 12 hours, and light intensity greater than or equal to 2000lux, and force the alpine azalea to bloom for 4-6 weeks. Although the patent can regulate the flowering period of alpine azalea, the operation is relatively complicated and difficult to accurately control the flowering period by regulating the ambient temperature and light. Therefore, how to reasonably and conveniently regulate the flowering period of azalea is currently a key research issue. Summary of the invention

[0004] The main purpose of the invention is to propose a method for regulating the flowering period of azalea, aiming to provide a method that is simple and convenient to operate and can accurately regulate the flowering period of azalea.

[0005] To achieve the above purpose, the present invention proposes a method for regulating the flowering period of azalea, when the azalea enters the color exposure period, the azalea color exposure period regulator is sprayed on the plants on the leaves, and a small sprayer is used to evenly spray the liquid until it drops from the leaves by a spray method, and an organic-inorganic compound fertilizer is applied to the soil around the root system; when the azalea enters the initial flowering period, the azalea initial flowering period regulator is sprayed on the plants on the leaves, and a small sprayer is used to evenly spray the liquid until it drops from the leaves by a spray method; when the azalea enters the late flowering period, the azalea late flowering period regulator is sprayed on the plants on the leaves, and a small sprayer is used to evenly spray the liquid until it drops from the leaves by a spray method; when the azalea enters the decay period, the azalea decay period regulator is sprayed on the plants on the leaves, and a small sprayer is used to evenly spray the liquid until it drops from the leaves by a spray method.

[0006] Since the number of days in the last flowering period is relatively short, for the convenience of comparison, the following text will describe the peak flowering period and the last flowering period as one stage, collectively referred to as the "peak and last flowering period". Among the various stages of the flowering period, the best viewing effect is the peak flowering period and the last flowering period, followed by the initial flowering period and the declining period. Therefore, extending the duration of the peak flowering period and the last flowering period is more practical than extending the initial flowering period or the declining period.

[0009] Preferably, the preparation method of the azalea initial flowering period regulator comprises the following steps: dissolving 2000 mg of gibberellin in 80-100 mL of ethanol to obtain solution A, dissolving 20-40 mg of 2,4-D (2,4-dichlorophenoxyacetic acid) in 20-40 mL of ethanol to obtain solution B, mixing solution A and solution B, adding 800-1200 mg of potassium dihydrogen phosphate, and then adding distilled water to make the volume to 1 L and stirring to mix evenly to obtain the azalea initial flowering period regulator.

[0010] Preferably, the azalea late flowering period regulator includes indoleacetic acid, gibberellin, naphthylacetic acid, diaminohydrazide and superphosphate, the concentration of the indoleacetic acid is 1000 mg / kg, the concentration of the gibberellin is 2000 mg / kg, the concentration of the naphthylacetic acid is 1500 mg / kg, the concentration of diaminohydrazide is 400-600 mg / kg, the concentration of the superphosphate is 20-40 mg / kg, and the azalea early flowering period regulator is sprayed once every 7-10 days during the late flowering period.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] (1) The method for regulating the flowering period of azalea provided by the present invention sprays a flowering period regulator at different flowering periods of azalea, thereby advancing the color exposure period and the initial flowering period of azalea, extending the peak flowering period with ornamental value, and improving the ornamental value of azalea.

[0015] (2) In the technical solution provided by the present invention, spraying a certain concentration of indoleacetic acid and gibberellin during the color release period can break the dormancy of azalea and promote early flowering, while maintaining the growth and development status of the azalea plants. In addition, organic and inorganic compound fertilizers are applied to the soil around the root system to prepare nutrients for the plant during the entire flowering period and ensure a good flowering state.

[0016] (3) In the technical solution provided by the present invention, a certain concentration of indoleacetic acid, gibberellin and naphthylacetic acid are sprayed at the end of the flowering period. Through the interaction of the three growth regulators, the end of the flowering period of azalea is significantly extended, bringing a better ornamental effect. DETAILED DESCRIPTION
