Embodiment 1

[0022] Step 1. Start the first flower promotion 180 days before the expected flowering. The first flower promotion lasts for 30 days. Use the first hormone solution to evenly spray the leaves of Cymbidium and pseudophosphorus every 5 days. Stem, the dose of the first hormone solution used each time is 100ml, in the present embodiment, choose gibberellin GA respectively 3 solution and 15% paclobutrazol PP 333 The solution is used as the first hormone solution, wherein, from the first time, the concentration of the first hormone solution used each time increases linearly in the range of 5 mg / L, and the concentration of the first hormone solution used for the first time is C 0 Choose 10, 30, 50 mg / L respectively; at the same time, during the first flower promotion period, fertilize the Cymbidium every 9 days, N:P:K=10:30:20 in the fertilizer, fertilize 100ml.

Abstract

The invention discloses a florescence control method for cymbidium hybridum, which comprises the following steps: 1. carrying out first flower-formation promoting starting from 180 days before a desired-to-flower date, lasting for 30 days, and applying a first hormone solution every 5 days, wherein the first hormone solution refers to a gibberellin GA3 solution or a 15% paclobutrazol PP333 solution, from the first time, the concentration of the first hormone solution is linearly increased by a span of 5-15 mg/L each time, and the concentration of the first hormone solution used for the first time is 10-50 mg/L; and 2. carrying out second flower-formation promoting starting from 30 days before the desired-to-flower date, lasting for 15 days, and applying a second hormone solution every 2 days, wherein the hormone solutes of the first hormone solution and the second hormone solution are the same, the concentration of the second hormone solution used for each time is the same, and the concentration is 3-7 mg/L. By using the method disclosed by the invention, the cymbidium hybridum can be in its flowering season 5-25 days ahead of schedule, and the flowering season can be in the same period as the Spring Festival; the florescence control range is larger, the control on florescence is more accurate, and the florescence control error is reduced to a range of minus or plus 2 days.

Description

technical field [0001] The invention relates to the field of plant cultivation, in particular to a method for regulating the florescence of Cymbidium phalanx. Background technique [0002] Cymbidium, also known as tiger head orchid and Himbilan, is one of the five largest potted orchids in the world. It has large and numerous flowers, gorgeous colors, and a long flowering period. It has been very popular in the international flower market in recent years. By the majority of Chinese fans of all ages. The flowering period of Cymbidium is generally from February to April. If the flowering period of Cymbidium is not regulated, its natural flowering period will just miss the Spring Festival, which will affect its commercial value. [0003] In the prior art, regulation of plant flowering includes physical regulation and chemical regulation. The physical control method mainly realizes the control of the flowering period through the management of temperature, light, humidity and w...
