A kind of control method of rhododendron rhododendron in winter

Abstract

The invention discloses a method for regulating the flowering period of Rhododendron rhododendron in winter. is 12 hours, the period is about 15-20 days, and GA is applied every 10 days during this period 3 Solution and KH 2 PO 4 The solution is once each; control the temperature of the Rhododendron in the greenhouse at 20-22°C, after 12 hours of natural light every day, continue to irradiate the Rhododendron with red and blue light for 3-4 hours, the period is about 15-20 days, and the period is every 10 days. Shi GA 3 Solution and KH 2 PO 4 The solution was applied once each; when the flower buds were elongated to 0.5cm, the temperature was 24-25°C to induce flowers, and after 12 hours of natural light exposure every day, the Rhododendron rhododendron was subjected to blue light irradiation treatment for 3-4 hours, and the period was about 15-20 days. By adjusting factors such as temperature, illumination time, light quality, plant growth regulator and the like, the present invention obtains rhododendron rhododendron with controllable flowering time, shorter flower-promoting time, and more tidy and beautiful flowering.

Description

technical field

[0001] The invention relates to the technical field of florescence regulation, in particular to a method for regulating the flowering stage of Rhododendron azalea in winter.

[0002] technical background

[0003] Western Rhododendron, belonging to Rhododendronaceae, is an evergreen shrub of Rhododendronaceae, which is bred by repeated hybridization between Chinese Rhododendron and European Rhododendron. Rhododendron azaleas are short and strong in plant shape, with large changes in flower shape and color, and rich colors. They are the most beautiful type of azaleas.

[0004] The western rhododendron requires loose, air-permeable, acidic soil rich in humus, that is, the soil pH value is 5.5-6.5. The suitable temperature for the growth of Rhododendron is between 18-22°C, and when the temperature is too low or too high, the life activities of Rhododendron will gradually weaken, and the growth and development speed will be slow. In addition, the suitable light i...

Embodiment 1

[0025] Embodiment 1: Carried out in a flower greenhouse in Liuzhou, Guangxi in 2015. Specific steps are as follows:

[0026] (1) Upper potting: Put the cutting seedlings of Rhododendron japonica into pots, and apply 0.3% compound fertilizer once a month after 1 month of upper potting, until the ground diameter of Rhododendron japonica reaches 1.0 cm, the height of seedlings is 25 cm, and the crown width reaches 25 cm, stop applying compound fertilizer Fertilizer; The substrate of upper pot is the discarded substrate that produces in eucalyptus or Chinese fir light substrate seedling raising process, and main component is by weight percentage, the chaff of 30 parts, the coir peat of 30 parts, the peat soil of 40 parts; Effectiveness of compound fertilizer N:P:K=20:12:20;

[0027] (2) Flower bud formation period:

[0028] ①On November 1, 2016, put 200 pots of Rhododendron "Guanzhongwang" in the greenhouse, control the temperature in the greenhouse at 15-17°C, the humidity at 7...
