The invention discloses a kind of method at regulation and control sword-leaved cymbidium florescence.The present invention promotes bud differentiation and growth by light temperature, water and fertilizer management before flower forcing, then using plant growth regulator mixed solution.After method provided by the invention one month, flowering rate more than 70%, solve sword-leaved cymbidium bloom it is irregular, the problem of florescence disunity and low flowering rate；Present invention operation is easy, and cost is relatively low, convenient to carry out, and the flower field for being especially suitable for various scales largely produces；The present invention solves the problems, such as sword-leaved cymbidium florescence control, make to expand to sword-leaved cymbidium florescence from annual 7 to December it is annual all can spend most increases into flower, realize sword-leaved cymbidium off-season flowering and bloom with that should save, so as to meet the needs of expansion market, economic benefit protrusion.
Description
Technical field
The present invention relates to field of plant cultivation, more particularly to a kind of method at regulation and control sword-leaved cymbidium florescence.
Background technology
Sword-leaved cymbidium (Cymbidium ensifolium), also known as autumn orchid, four seasons orchid, are extensively by joyous in Chinese Terrestrial orchid platymiscium
The cultivation fancy breed met.Different from other state's orchid species, the sword-leaved cymbidium florescence is longer repeatedly to bloom, but it is unmanageable it is consistent into
Take time, and flower can not be gone out on time in the important festivals busy season such as the Spring Festival, New Year's Day, thus how regulation florescence, grasp sword-leaved cymbidium it is accurate
Regulation measure of blooming by as improving the important channel of its commodity value and market demand.
, can be real by controlling illumination, temperature, nutrition-allocated proportion and plant growth regulator in the research of florescence control
The regulation and control of blooming of existing a variety of ornamental plants.But comprehensive not enough to the research in terms of sword-leaved cymbidium florescence control at present, the prior art
In there are no adjust sword-leaved cymbidium florescence method report.
The content of the invention
The shortcomings that it is an object of the invention to overcome the prior art and deficiency, there is provided a kind of method at regulation and control sword-leaved cymbidium florescence.
The purpose of the present invention is achieved through the following technical solutions：A kind of method at regulation and control sword-leaved cymbidium florescence, includes the following steps：
(1) light temperature, water and fertilizer management before flower forcing：Carry out before florescence control 30~60 days, greenhouse experiment control is in temperature 25 on daytime
~32 DEG C, night is not less than 10 DEG C, and humidity is 70~80%, and illumination is in below 60000LUX；Change the liquid manure bar of cultivation
Part, promotes plant to be converted by nutrient growth to reproductive growth, fertilizer ratio N using the high potassic fertilizer of high phosphorus:P:K=(8~12):
(25~35):(15~25), Effects of Fertilization Frequency are 7~14 days 1 time, and concentration of applying fertilizer every time is is diluted with water 2000~4000 times, water
Sub-control is made as applying once for every 5 days, is substantially carried out leaf；
(2) apply plant growth regulator mixed solution and promote bud differentiation and growth：
1. after step (1) is handled 30~60 days, using hormone solution, to promote growth of flower bud, with foliage-spray to leaching
Drench as appropriateness；Hormone solution contains gibberellin (GA3) 30-100mg/L and basic element of cell division 6-benzyl aminopurine (6-BA) 50-
200mg/L；
2. step according to weather condition, every 7~10 days sprays hormone solution once after 1. handling, it is desirable to which blade face all moistens
And there is drop to drip, continuous processing 3 times；
3. step 2. continuous processing three times after, continue to spray 0.5g/L N:P:K=(8~12):(25~35):(15
~25) the high potassic fertilizer of high phosphorus, until 2 months after the early flowering season, Effects of Fertilization Frequency is 7~14 days 1 time；Period is carried out using shading net
60~80% shading treatments, make illumination control in below 60000Lux.
Fertilizer ratio applied in the period of nutrient growth described in step (1) is usually N:P:K=30:10:10.
The fertilizer ratio in the high potassic fertilizer of high phosphorus described in step (1) is preferably N:P:K=10:30:20.
Nocturnal temperature described in step (1) is preferably 10~20 DEG C.
Hormone solution described in step (2) is also containing the fertilizer that concentration is 0.5g/L, the N in fertilizer:P:K=(15~
30)：(8~12)：The fertilizer of (15~25), to promote spray to extend.
Tween-20 of the hormone solution also containing concentration for percent by volume 0.05~0.5% described in step (2), with
Strengthen treatment effect.
The composition of hormone solution described in step (2) is preferably as follows：Gibberellin (GA3) 30~100mg/L, cell division
50~200mg/L of plain 6-benzyl aminopurine (6-BA), concentration are the fertilizer of 0.5g/L, percent by volume 0.05~0.5%
Tween-20, solvent are water；Wherein, the N in fertilizer:P:K=(15~30)：(8~12)：(15~25).
The composition of the hormone solution is more preferably as follows：Gibberellin (GA3) 50mg/L, basic element of cell division 6- benzyl amino is fast
Purine (6-BA) 100mg/L, fertilizer, the Tween-20 of percent by volume 0.5% that concentration is 0.5g/L, solvent is water；Wherein, it is fertile
N in material:P:K=20:10:20.
The processing time for promoting bud differentiation and growth using plant growth regulator mixed solution described in step (2)
It is annual all can, wherein optimal to treatment effect during November annual 4.
The present invention is had the following advantages relative to the prior art and effect：
1. this method applies the high potassic fertilizer of high phosphorus, promote plant, promote bud differentiation using plant growth regulator and stretch
It is long, after one month, flowering rate more than 70%, solve sword-leaved cymbidium bloom it is irregular, the problem of florescence disunity and low flowering rate.
2. this method operation is easy, cost is relatively low, convenient to carry out, and the flower field for being especially suitable for various scales largely produces.
3. economic benefit protrudes, the present invention solves the problems, such as sword-leaved cymbidium florescence control, expands sword-leaved cymbidium florescence from annual 7 to December
Open up whole year all can spend most increases into flower, realize sword-leaved cymbidium off-season flowering and bloom with that should save, so as to meet to expand market
Demand.
