Description

A kind of regulation and control method at camellia florescence
Technical field
The invention belongs to field of plant growing technology, and in particular to a kind of regulation and control method at camellia florescence.
Background technology
Camellia (Camellia japonica) also known as camellia, it is Theaceae Camellia Plants, evergreen shrubs or little Qiao Wood is high up to 3~4m.Camellia flower appearance is plentiful, dignified graceful, is one of ten big famous flower of Chinese tradition.And world's famous flower it One, camellia is the evergreen shrubs of camellia section.Resistance to winter, graceful sieve etc..Trunk is smoothly hairless.Leaf elliptical or oval shape, edge have Serration, keratin, surface bright green.Hua Dan is generated to being born in axil or branch top, and petal is bordering on circle, and mutation polyphyll petal is reachable 50~60, colored color is red, white, yellow, purple to have, very bright-coloured.Florescence is different because kind is different, from October to next year There is the flowers are in blossom to put between April.Capsule is circular, and autumn Mo is ripe, but most of hose-in-hoses can not result.The bud differentiation of camellia is begun 6~July, the florescence, the florescence of wherein most kind was in or so March between April in December to next year.Camellia has The proud plum strength of character of " having that camellia is very durable only, solely can account for spring breeze by the deep moon ", have again " spending numerous bright red, take dawn rosy clouds by force deeply " icepro tree peony it is fresh It is gorgeous, therefore be exactly the Woody flower for being rich in great reputation since ancient times, in the Tang and Song Dynasty two towards the border reached the peak of perfection has been reached, until 17 generation To record after introducing Europe, cause to cause a sensation, also therefore obtain the good name of " world's famous flower ", leaf elliptical or oval shape, there is serration at edge, Keratin, surface bright green.
At present, in the purpose at China's control camellia florescence, mainly promote camellia open during National Day.It is existing In technology, by commonsense methods such as the single heating of routine plus light, winter florescence control is carried out to camellia, it is difficult to effectively Regulate and control the florescence of camellia, and plant florescence control has the selection in kind different, physical regulating and chemical regulation, regulates and controls method It is all relatively simple, but plant needs a variety of factors to influence in growth course.
The content of the invention
It is an object of the invention to:For above-mentioned deficiency, the invention provides a kind of regulation and control at camellia florescence Method.The present invention can break the natural law grown and bloomed of camellia, the florescence of effective regulation and control camellia, together When effectively rich water quality management and hormone regulating and controlling have been carried out to camellia so that the florescence of camellia ensure it is consistent on the basis of, Efficiently controlled, realize camellia off-season flowering so that the growing and cultivating of camellia complies with the market demand, significantly Improve the benefit of camellia grower.
In order to achieve the above object, present invention employs following technical scheme:
A kind of regulation and control method at camellia florescence, comprises the following steps:
(1)Hormone regulating and controlling:90d before expectation camellia is bloomed is proceeded by promotees flower for the first time, and rush florescence first time is limited to 2~3 hormone solution sprinklings are carried out in 30d, 30d, spraying time and second of spraying time are separated by 13~15d first, remaining Every 9~11d sprinklings once, second of rush flower 20~25d before florescence is expected is carried out, and every 7~9d carries out a hormone Spray solution, the hormone solution are heteroauxin solution, promote every time the heteroauxin solution concentration that uses of flower for 300~ 500mg/L indolebutyric acid leaching 3~5h of root, and spray 900~1000 times of ethephon (CEPHA),2-(chloroethyl) phosphonic acids 1 time;
(2)Temperature and humidity management:Nocturnal temperature, using air conditioner facility, is progressively reduced to by 55~60d before the flowers are in blossom in expectation camellia 12~13 DEG C, it is maintained at 19~21 DEG C daytime, and continues 35d, then gradually rise temperature, ensures that its nocturnal temperature rises to 16 ~20 DEG C, daytime, growth temperature was maintained between 22~25 DEG C, and humidity remains at 81~84%;
(3)Rich water quality management:Start in the 30d for promoting the florescence to before blooming, increase fertilizer application frequency for the weak plant of growth potential, often It is secondary to be well mixed and applied fertilizer using 30~40 parts of phosphate fertilizer, 10~15 parts of potash fertilizer, 25~35 parts of farm manure, every 7~10d fertilisings one It is secondary, until plant growing way is basically identical, for the strong control water of growing way, fertilizer, during the weak parent's fertilising of growing way, the strong parent of growing way Do not refertilize;
(4)Illumination management:Promote to carry out light filling to camellia since 35d in the florescence, before daily sunrise or post sunset light filling is big In equal to 3h light application times, intensity of illumination is kept in illumination period in 1500~1700Lux.
Further, in step(1), described second promote the florescence between nocturnal temperature be 16~18 DEG C, day temperature 21 ~23 DEG C, nocturnal temperature heats up 1~2 DEG C per 5d, and day temperature heats up 2~3 DEG C per 10d, and 11 the end of month were maintained at 25~27 DEG C, treated Camellia controls temperature when outputing bud be 16~18 DEG C.
Further, in step(2), in the temperature and humidity management camellia operating period temperature is adjusted to 16~18 DEG C.
Further, in step(3), camellia Post flowering strengthens Nutrition Management in the water and fertilizer management, increases N fertilizer and uses Amount, it is well mixed and is applied fertilizer using 65~85 parts of urea, 125~155 parts of phosphate fertilizer, 30~45 parts of farm manure, every mu is applied 50kg, Imposed in three times, every mu of initial bloom stage applies 20kg, and every mu of full-bloom stage applies 15kg, and every mu of Flowers ending applies 15kg.
Further, in step(4), promote for second in the illumination management to carry out while flower to increase illumination management 18~ 20d, increase by 4~5h light application times daily, intensity of illumination is 2200~2400Lux, is then managed according to circadian.
In summary, the present invention has the positive effect that as a result of such scheme:
(1)Flower forcing is carried out using temperature control method, breaks the rest period of camellia, rapidly promotes camellia flower growth, and can be effective Regulate and control the florescence of camellia;Second of rush flower increases intense light irradiation management daily while using hormone solution regulation florescence, makes mountain The flowering rate of camellia improves 12.7%;Temperature is adjusted to 16~18 DEG C by camellia duration of flowering, can extend what is opened The florescence of camellia, and can ensure the opening of other unopened camellias, and greatly improve camellia views and admires quality;The present invention From the growth rhythm of more comprehensive control camellia the florescence of camellia can be accurately controlled so as to more effective;Science The rational application of fertilizer, nutriment is more comprehensive, promotes the formation of soil granular structure, coordinates the ratio of soil air and water, Make loosing soil, increase water conservation, insulation, the ventilative, ability of fertilizer conservation, meet camellia various needed for fast growth process Nutritional ingredient, fertilizer efficiency is improved, adjust soil, ensure that camellia still can healthy, high quality life in change growth rhythm process It is long.
(2)The present invention can break the natural law grown and bloomed of camellia, effective regulation and control camellia Florescence, while effectively rich water quality management and hormone regulating and controlling have been carried out to camellia so that the florescence of camellia is ensureing unanimously On the basis of, efficiently controlled, realize camellia off-season flowering so that the growing and cultivating of camellia is complied with market and needed Ask, substantially increase the benefit of camellia grower.
