Abstract

The invention discloses a method for promoting heliconia caribaea to bloom in advance, which comprises the following steps: in the last ten days of February, selecting healthily-growing stock plant clumps, segmenting small plant clumps from the stock plant clumps, and selecting 2-3 young plants with one leaf and one heart or just-epigeal small plant clumps of lateral buds (surculus suckers) with 3-4 effective leaves; planting the young plants or the just-epigeal small plant clumps into soil with good lighting condition, convenient irrigation and high content of organic matter; watering, fertilizing, and then cultivating and managing later until the heliconia caribaea blooms; and at the beginning of May, June and July, spraying 200-300ppm of naphthylacetic acid (NAA) at the front surfaces and the back surfaces of the leaves of the heliconia caribaea, wherein the spraying amount is preferable to be the droplet just dropped. The method can promote the heliconia caribaea to bloom 1-2 months earlier during the golden week of the National Day at the beginning of October, and the heliconia caribaea can continuously bloom at the New Year's Day and the Spring Festival, thereby not only prolonging the flowering phase, but also improving the blossom rate to be more than 30%.

Description

A kind of method that promotes heliconia caribaea to bloom in advance
Technical field:
The invention belongs to biological technical field, be specifically related to a kind of method that promotes heliconia caribaea to bloom in advance.
Background technology:
Venezuela heliconia (Heliconia) is heliconiaceae (Heliconiaceae) herbaceos perennial, its main original producton location be in, South America torrid areas and part island, the South Pacific Ocean, the whole world has 200-250 kind, mutation, cultivated species and crossbreed etc. approximately, does not have natural distribution in China.The bract of venezuela heliconia has multiple colors such as dark red, pink, pink, yellow, orange, green, white and purple, and spends greatly, and the flower type is peculiar and gorgeous colourful, florescence reaches the several months, both can do the garden landscape plant and arrange, can potted plantly view and admire again, make the superior material of cut-flower, flower arrangement and dried flower especially.
Rich red venezuela heliconia (Heliconia bourgaeana Petersen) is from being in late 1990s from the U.S. with a kind of flowers with very high ornamental value of introducing of Thailand by South China Botanical Garden Chinese Academy of Sciences, can be in the original producton location by seed propagation and division propagation, mainly adopt division propagation in the Guangzhou of introducing a fine variety ground, under the conventional cultivation management condition, rich red venezuela heliconia is inhaled bud and is begun to sprout to the required time of blooming long, generally need 13-15 month, and it is bloomed in December usually, and flowering rate is lower, only is about 15%.
Do not see that about the technology and the method for rich red venezuela heliconia florescence control and raising flowering rate document or patent report are arranged at present.
Summary of the invention:
The purpose of this invention is to provide a kind of method that promotes heliconia caribaea to bloom in advance, all right kind of blooming period prolonging of this method and raising flowering rate, long in order to the florescence that solves in the existing rich red venezuela heliconia cultivation method, slow and the low problem of flowering rate of florescence can improve its ornamental value and economic worth better.
The present invention carries out division propagation by the lateral bud that utilizes rich red venezuela heliconia, selects suitable planting environment, in the late Febuary field planting, carries out intensive cultivating, rationally uses measures such as plant growth regulator, has realized purpose of the present invention.
The method of promotion heliconia caribaea to bloom in advance of the present invention may further comprise the steps:
(a) in late Febuary, select the maternal plant clump of robust growth, the little strain clump of cutting therefrom, choosing effective leaf is 3 to 4, the little strain clump of side (suction) bud that has the shoot of 2-3 tool 1 leaf 1 heart or just be unearthed, field planting in the soil good at illumination condition, that irrigation is convenient, the content of organic matter is high, the fertilising of watering, cultivation management to rich red venezuela heliconia is bloomed routinely later on;
(b) at the beginning of 5 months, at the beginning of 6 months and at the beginning of 7 months, spray methyl (NAA) 200ppm~300ppm in the blade face and the blade back of the red venezuela heliconia of richness, the amount of spraying is dripped with the firm dropping liquid in blade face and is advisable.
It is 3%~5% sand loam that described soil of the present invention is preferably the content of organic matter.
In order to carry out intensive cultivating; realize the production of scale; when carrying out field planting; press earlier 75 centimetres of furrow face widths; 25 centimetres of furrow widths, dark 20 centimetres furrow, general every furrow kind 1 row, spacing in the rows is 75 centimetres~80 centimetres; line-spacing is 95 centimetres~100 centimetres, 800 clumps~900 clumps of every mu of about field planting of field planting.
When the little strain clump of cutting, preferably select the cloudy day or overcast and rainy, help improving the survival rate of little strain clump.
The described fertilising of watering will be satisfied rich red venezuela heliconia grow needed nutrient and moisture.
Described methyl (NAA) can buy from market.
By utilizing the method for promotion heliconia caribaea to bloom in advance of the present invention, select suitable strain clump to carry out division propagation and suitable planting environment, in the late Febuary field planting, carry out intensive cultivating, rationally use plant growth regulator, can make rich red venezuela heliconia shift to an earlier date 1-2 month blooms, can can also continue to bloom on the New Year's Day and the Spring Festival in blooming during golden week on National Day at the beginning of 10 months, this has not only prolonged the florescence, also improved flowering rate, its flowering rate can reach more than 30%.Therefore, on producing, use this method and plant rich red venezuela heliconia, can during National Day, New Year's Day and the Spring Festival, supply rich red venezuela heliconia potted flower or cut-flower, can improve its economic benefit widely, and have good ecological and social benefit.Characteristics such as that this invention has on producing is practical, operability good and benefit is superior.
Embodiment:
Further explain the present invention below in conjunction with concrete embodiment.Should be understood that these examples only are not used in to be used to the present invention is described limits the scope of the invention.
Embodiment 1:
