The thick leaf of alpine rose branch is big, and the branch amount is very little, and the breeding difficulty is big, cultivation management technology content height.The natural florescence of alpine rose will bloom in advance in 3～May, needed alpine rose is carried out florescence control.
In the prior art, heat, add commonsense methods such as light by routine single, alpine rose is carried out the florescence control in winter, be difficult to the effectively florescence of regulation and control alpine rose.
Summary of the invention
The method that the purpose of this invention is to provide a kind of regulating and controlling blooming period of rhododendron in winter, this method can effectively be regulated and control the florescence of alpine rose.
The objective of the invention is to be achieved through the following technical solutions:
The method of regulating and controlling blooming period of rhododendron in winter of the present invention comprises step:
A, forced dormancy period: selection need be carried out the alpine rose of florescence control, puts into the environment below 10 ℃, cultivation at low temperature 2-3 month;
B, flower forcing phase: the environmental temperature of described alpine rose is increased to about 20 ℃ gradually from 10 ℃.
As seen from the above technical solution provided by the invention, the method of regulating and controlling blooming period of rhododendron in winter of the present invention, because the alpine rose that at first needs is carried out florescence control is put into the environment below 10 ℃, carry out 2-3 month forced dormancy period, then the environmental temperature of alpine rose is increased to about 20 ℃ gradually from 10 ℃, carries out flower forcing.Can break the natural law of growing and blooming of azalea, effectively regulate and control the florescence of alpine rose.
Embodiment
Its preferable embodiment of the method for regulating and controlling blooming period of rhododendron in winter of the present invention is to comprise
Step 1, forced dormancy period: selection need be carried out the alpine rose of florescence control, puts into the environment below 10 ℃, cultivation at low temperature 2-3 month;
Step 2, flower forcing phase: the environmental temperature of described alpine rose is increased to about 20 ℃ gradually from 10 ℃.
Selected alpine rose is a nature florescence kind early in the described step 1.The natural florescence of alpine rose will bloom in advance in 3～May, at first will select some florescences kind early, and well-developed bud of sufficient amount and the good plant type of commodity property are arranged.Plant has 5～6 poppyhead buds that expand at least.
Selected alpine rose is preferably that chilling requirement is low, the kind of easy flower forcing, and the kind that the promptly needed athermobiosis phase is short can suitably shorten time of forced dormancy period like this.
In the described step 2, the intensification during the described flower forcing begins and will slowly heat up, first week, the environmental temperature with described alpine rose was increased to about 20 ℃ gradually from 10 ℃, since the 7th day, temperature just maintained a relatively stable state, and temperature keeps 20-22 ℃ of daytime, 18-20 ℃ of night.Described environmental temperature daytime is the highest to be no more than that 30 ℃, night are minimum to be not less than 15 ℃.If maximum temperature surpasses 22 ℃, the reverse of bud to leaf bud can appear, and reversion rate increases gradually with the increase of temperature.
Need during the described flower forcing alpine rose is carried out light filling, illumination every day was more than or equal to 12 hours, and illuminance is more than or equal to 2000lux.
Generally began alpine rose is carried out light filling from the 7th day described flower forcing phase, before sunrise every day or post sunset light filling about 3 hours.Be preferably in post sunset and carry out light filling.
Light filling uses and is specifically designed to the Philip sodium vapor lamp of strengthening photosynthesis of plant, or other lamp.But the light filling time is difficult for surpassing 16 hours, and the long blade that also can cause is taken out long, blade variable color.During whole flower forcing,, allow plant accept natural daylight regardless of weather condition more as far as possible.Check illumination parameter.Air humidity 60～90% can be 60,70,80,90% etc., keeps ventilating.
It should be noted that the good flower forcing time of GPRS especially.According to the asynchronism(-nization) of listing, the measure of taking is also different.This is because alpine rose self has dormancy period, if it was bloomed in the night time in year, will break its dormancy.Its free flowering time of the time interval of flower forcing is near more, and the flower forcing process that needs is short more, otherwise then long more.As begin flower forcing in December, the flower forcing phase needed about 6 weeks, if begin flower forcing by the end of January, the flower forcing phase needed about 4 weeks.When bud is slowly heaved, when showing look, can sell in bud.
Specifically should select the potted flower of reproductive stage unanimity, bud maturation in advance for use, put into freezer and carry out mandatory dormancy a period of time, can make potted flower bloom neatly this natural law after satisfying its athermobiosis according to the Date Required in client and market; Adopt the potted flower after mandatory dormancy then, place and impel it to bloom in the green house, will go on the market through the potted flower after the regulation and control at last on schedule.The present invention can make alpine rose irregularly bloom to reach by market demands and bloom, thereby break the natural law of growing and blooming of azalea by artificial adjustment, and having overcome does not have colored drawback dull season, can be by the demand supply of material.And potted flower leaf look dark green glossy, pattern is gorgeous, the flower type big, the florescence is long, quality good, value is high.
