Abstract
The invention discloses a kind of methods at regulation cold orchid florescence.The present invention passes through light temperature, water and fertilizer management before flower forcing, and Discrete control transplants temperature, application special fertilizer promotes bud differentiation and development.Using method provided by the invention, the cold orchid florescence can be shifted to an earlier date, cold orchid is solved and bloom irregular, florescence skimble-scamble problem；Operation of the present invention is easy, and cost is relatively low；Solve the problems, such as cold orchid florescence control, the florescence before making cold orchid be scattered in mid-autumn to the Spring Festival stablized on National Day to mid-autumn festival celebration, and then realized application of the cold orchid as festival celebration flowers, to meet the needs of market, economic benefit is prominent.
Description
Technical field
The present invention relates to field of plant cultivation, in particular to a kind of method at regulation cold orchid florescence.
Background technique
Cold orchid (Cymbidium kanran), be orchid family (Orchidaceae) Cymbidium (Cymbidium) perennial herb plant
Object, the slender bodybuilding of plant type, it is leaf it is compact tower, flower appearance is gentle and graceful elegant, and thin narrow valve type, the fragrance of a flower is pure elegant, fragrant and original,
Pot flowers are widely used as, there are biggish ornamental values and the economic values.However, cold orchid is often when the cold season in a year in midwinter,
Offer it is gorgeous spit virtue, the florescence is asynchronous, and the florescence is sorry with festival celebration sequence, and so that it is difficult to festival celebration flowers market at home competition
Power.The florescence physiological responses research of different disposal is established for development cold orchid florescence control technology formulation by cold orchid solid
Basis, cold orchid florescence control technology have the promotion of the formulation and cold orchid market value that promote cold orchid cultivation technique specification great
Meaning.
At present in florescence control research, by control temperature, nutrition-allocated proportion and plant growth regulator, it can be achieved that more
The regulation of blooming of kind ornamental plant.However it is still not comprehensive to the research of cold orchid florescence control technical aspect.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of methods at regulation cold orchid florescence.
The purpose of the invention is achieved by the following technical solution: including the following steps:
(1) light temperature, water and fertilizer management before flower forcing: 30 ~ 60 d before florescence control, i.e. early Febuary, manual adjustment temperature are not less than daytime
20 DEG C, when night is not less than 10 DEG C, using spraying or watering mode, it is ensured that humidity is 65 ~ 85% in canopy, when noon illumination is strong
Shaded using shading net；Change the water and fertilizer condition in cultivation, the first two months application of phosphoric acid potassium dihydrogen promotes plant by nutrition
Growing into the conversion of reproductive growth, concentration of fertilizer are as follows: potassium dihydrogen phosphate extension rate is 500 times, and Effects of Fertilization Frequency is that 10 d are primary,
Fertilising sprays every time for blade back, co-administers 6 times；Moisture control is that 10 d watering is primary, after entering April current year, when watering
Between be changed to that 3 d are primary, and watering time does a little adjustment according to weather condition and matrix dry and wet degree；
(2) promote bud differentiation and development: early April started to late June, cold orchid potting was placed in 28 DEG C of daytime temperature, night temperature
In 18 DEG C of temperature-controlling green house, every 7 d sprays a 5g/L flower the more No. 3, and flower the more No. 3 are flower forcing budding fertilizer, composition ratio
Example: nitrogen, phosphorus, potassium three elements mass ratio are 9:45:15.It is required that cold orchid blade back is all sprayed to.Spray the processing of flower the more No. 3
It is carried out in fine day, sprays 3 d of front and back and drought stress is carried out to cold orchid plant.
During processing, when illumination is stronger, 60 ~ 80% shading treatment is carried out using shading net, makes light control 2500
Lx or less.
Water in step (1) and step (2) for diluting fertilizer is sterile distilled water.
The present invention has the following advantages and effects with respect to the prior art:
1. this method is using segmentation liquid manure, temperature integrated regulation measure, so that cold orchid flowering rate is more than 80%, consistency of blooming is high,
Solve the problems, such as that cold orchid flowering rate is low, it is irregular to bloom, single scape quantity of blossoming obviously increases.
2. this method is easy to operation, cost is relatively low, convenient to carry out, is especially suitable for having certain environment control facility
The large-scale production of flower field and nursery.
3. economic benefit is prominent, the present invention solves the problems, such as cold orchid florescence control, the cold orchid florescence is made to be stable at mid-autumn to National Day
Period is open, has both been able to satisfy festival celebration flowers market great demand amount, while can also obtain higher selling price, and then realizes cold
Blue standardized planting, the target for promoting occupation rate of market.
Specific embodiment
Further detailed description is done to the present invention below with reference to example, embodiments of the present invention are not limited thereto.
1 cold orchid of embodiment (Cymbidium kanran), the flower forcing processing time is on April 1st, 2018, early flowering season 2018
On September 10,.
Invention group
Step 1: with cold orchid (Cymbidium kanran) it is material, it chooses 3 years 300 basins of raw healthy seedling and (selects and connect in Fujian
City orchid limited liability company), since 2 the first tenday period of a month in month in 2018, changes the light and temperature condition in cultivation, be not less than daytime
20 DEG C, night is not less than 10 DEG C, using spraying or watering mode, it is ensured that humidity 65 ~ 85%, adopt when strong by noon illumination in canopy
Shaded with shading net；Change the liquid manure nutritional condition in cultivation, 500 times of potassium dihydrogen phosphates is applied, to spray cold orchid blade back
It is advisable, Effects of Fertilization Frequency is that 10 d are primary, is co-administered 6 times；Moisture control is that 10 d are used once；
After entering April current year, two are entered step
Step 2: temperature, water management, the more No. 3 promotion bud differentiation of flower and growth.
1, after step 1 handles 60 d, cold orchid potting is placed in 28 DEG C of daytime temperature, in the temperature-controlling green house that 18 DEG C of night temperature.
2, it is primary to be changed to 3 d for watering time.
3, with flower the more No. 3 for flower forcing budding fertilizer, component ratio: nitrogen, phosphorus, potassium three elements mass ratio are 9:45:15, according to
Weather condition is carried out in fine day, and every 7 d sprays a 5g/L, and continuous processing 6 times, it is desirable that cold orchid blade back is all sprayed to.Place
The front and back of reason pays attention to cold orchid control water for three days.
4, during step 3 processing, when illumination is stronger, 60 ~ 80% shading treatment is carried out using shading net, makes light control
In 2500 lx or less.
Control group: since 2 the first tenday period of a month in month in 2018, in a natural environment, temperature did not did manual control, and lighting process is same
Invention group applies slow-release fertilizer according to conventional cultivation mode, and 3 ~ 5d watering is primary.
Table 1 lists cold orchid early flowering season and flower number after processing.Early flowering season, which refers to, uses up entirely after flower forcing processing to first
The open time.
Table 1
The above embodiment is a preferred embodiment of the present invention, but embodiments of the present invention are not by the limit of above-described embodiment
System, other any changes, modifications, substitutions, combinations, simplifications made without departing from the spirit and principles of the present invention,
It should be equivalent substitute mode, be included within the scope of the present invention.
