Problems solved by technology

[0006] The purpose of the present invention is to provide a flame orchid florescence regulation method for the defects of the vegetative growth time of the flame orchid that is too long, the plant height is too high, and the production cycle is long. By adjusting the childhood stage of the flame orchid, it can enter the reproductive growth period as soon as possible. , so as to shorten its cultivation cycle, and at the same time regulate the flowering period of the flame orchid according to the target flowering period, and promote the development of potted flower sales

Embodiment 1

[0023] The selected target flowering period is the National Day, that is, October 1st is the target flowering period. In May 2017, a total of 90 flame orchid tissue culture seedlings with 2-year-old seedlings, good growth, robustness, and aged stems with a height of more than 5 cm at the plant base were selected (the variety is "Renanthera Kalsom'Red Dragon'", and the plant height is at 25cm), set 3 treatment areas (three repetitions), each 30 plants in each area.

[0024] 1. Nutrient and water management

[0025] Fertilization adopts high phosphorus fertilizer, and the ratio of nitrogen, phosphorus and potassium is N:P 2 o 5 :K 2 O=9:45:15, applied 3 times per month, the concentration was 0.02%, and the application amount was 110mL / plant. Moisture management is sprayed once a day in the morning and evening, and the light is controlled at 70,000 to 90,000 lux.

[0031] The selected target flowering period is the National Day, that is, October 1st is the target flowering period. In June 2017, a total of 90 flame orchid tissue culture seedlings with 2-year seedling age, good growth, robustness, and aged stems with a height of more than 5 cm were selected (the variety was "Renanthera Kalsom'Red Dragon'", and the plant height was between 25cm), set 3 treatment areas (three repetitions), each 30 plants in each area.

[0032] 1. Nutrient and water management

[0033] Fertilization adopts high phosphorus fertilizer, and the ratio of nitrogen, phosphorus and potassium is N:P 2 o 5 :K 2 O=9:45:15, apply twice a month, the concentration is 0.03%, and the application amount is 110mL / plant. Moisture management is sprayed once a day in the morning and evening, and the light is controlled at 70,000 to 90,000 lux.

Abstract

The invention belongs to the field of plant cultivation, and relates to a method for regulating and controlling flowering stage of renanthera. The method comprises the following steps: selecting a plant at the age longer than 2 years and applying a high phosphorus fertilizer, spraying once in the morning and evening, and controlling illumibation at 70,000-90,000 lux; spraying uniconazole before regulation and control of the flowering stage; and carrying out foliage spray and root-irrigation treatment on the renanthera by using a growth regulator thidiazuron 60 days before the target floweringstage of the renanthera. The flowering stage of the renanthera is regulated and controlled by spraying the uniconazole and using a growth regulator TDZ, the problems that the juvenile phase of the renanthera is over long, individuals do not bloom consistently, commercialized consistent harvesting cannot be achieved, and the renanthera cannot be supplied for markets on a large scale are solved, large-scale production of the renanthera in tropical orchids is promoted favorably, improvement of the quality of the flowers is promoted, and the method has the characteristics of simplicity and convenience, low cost, easiness in operation, high flower forcing consistency and the like, and has a sustainable development significance on development of the tropical orchid industry and scientific research.

Description

technical field [0001] The invention belongs to the field of plant cultivation, and relates to a method for regulating the florescence of plants, in particular to a method for regulating the florescence of flame orchids. Background technique [0002] Flame Orchid (Renanthera coccinea Lour.) is a perennial, epiphytic or semi-epiphytic rare tropical orchid of the genus Flame Orchid of the Orchidaceae Vanda family. It is a uniaxial stem, which grows vigorously. The flower stem grows laterally and is in the shape of a large panicle. There can be hundreds of flowers, mostly red or orange yellow, and the flowers are gorgeous. [0003] There are about 21 native species and 2 varieties of Flame Orchid, which are naturally distributed in tropical Asia, and Hainan Island is its natural distribution area. There are three native species of Flame Orchid in my country, namely Yunnan Flame Orchid, Flame Orchid and Chinese Flame Orchid, which are naturally distributed in Hainan, Yunnan and...
