Embodiment 1
[0031] Embodiment 1: Take the alpine rhododendron variety 'Furnivall's Daughter' born in 6 years as an example, the present invention is further described:
[0032] (1) Cultivation substrate selection
[0033] The cultivation medium is mixed with humus, peat and red soil according to the volume ratio of humus: peat: red soil (that is, red soil) is 2:1:1, and the acidity of the substrate is adjusted to pH 5.5-6.5; The substrate drains well and at the same time has a certain water retention capacity.
[0034] (2) fertilization
[0035] 1. at the end of March, when Rhododendron alpine just began to germinate, the Aibeishi (APEX) controlled-release fertilizer produced by U.S. Simplot Company was applied once, and the consumption was 1.5g / kg of cultivation substrate. Total nitrogen 18.0%, water-soluble phosphoric anhydride 6.0%, water-soluble potassium 12.0%, water-soluble magnesium 1.7%, chelated sulfur 7.3%, chelated copper 0.05%, chelated iron 0.5%, chelated manganese 0.05 %,...
Embodiment 2
[0048] Embodiment 2 except that following measures are different, all the other measures are identical with embodiment 1.
[0049] (1) Cultivation substrate selection
[0050] The cultivation medium is mixed with humus, peat and red soil according to the volume ratio of humus: peat: red soil (that is, red soil) is 1:1:1, and the acidity of the substrate is adjusted to pH 5.5-6.5;
[0051] (2) fertilization
[0052] 1. The consumption of controlled-release fertilizer is 2.0g / every kilogram of cultivation medium, and described controlled-release fertilizer is identical with embodiment 1.
[0053] ②From March to early June, fertilize the roots with 0.15% ammonium sulfate solution every 10 days, and use 100ml of substrate per liter each time, and use 0.15% water-soluble fertilizer once every 15 days Foliar spraying, each plant consumption is 150ml, and the N content is 20% in the described full water-soluble fertilizer, and the P 2 o 5 Content is 10%, K 2 O content is 20%, a...

Abstract
The invention discloses a method for increasing the potted alpine rose number and improving the flower bud quality. The method comprises the culture medium matching, fertilizing, trimming, temperature control, drought stress treatment and illumination control. Controlled-release fertilizer can be fertilized once in the end of March; from March to the early June, ammonium sulfate can be fertilized to the root once every ten days, and full water soluble fertilizer can be fertilized to the leaf surfaces once every fifteen days; from the middle of June to the end of summer, mixed liquid fertilizer can be fertilized to the root and the leaf surfaces once every ten days; in autumn, monopotassium phosphate can be sprayed on the root and the leaf surfaces once every fifteen days; from the middle of June to the early August, the temperature is controlled within 23-28 DEG C; from the early July to the early August, the water can be controlled for 20-30 days; from the end of May to the end of August, the luminous intensity can be controlled within 33000-450001x. According to the method disclosed by the invention, the number of flower buds can be increased by 28-30% than that of conventional potted plants, the transverse diameter of the flower buds is increased by 13-18%, the problems of potted alpine rose that the flower bud forming rate is low and the flower bud quality is poor can be effectively solved, and the ornamental value of the potted alpine rose is obviously increased.
Description
technical field [0001] The invention belongs to the technical field of cultivation methods of woody ornamental plants, and in particular relates to a technical method for promoting flower bud formation of potted alpine rhododendron and improving flower bud quality. Background technique [0002] Rhododendron (Rhododendron) is a world-recognized rare and precious ornamental flower, and it is also one of the top ten famous flowers in my country. Alpine Rhododendron is a large category of abundant Rhododendron resources, generally referring to the evergreen Rhododendron in subgenus Subgenus Hymenanthes, Subgenus Rhododendron and Subgenus Azaleastrum , and their hybrids.
