Abstract
A method for regulating the blossoming period of spring dendrobium nobile featues that after the blades of its pseudobulb are fully developed, the mixed solution containing paclobutrazol and abscisic acid is sprayed onto the surface of blades for promoting the pseudobulb to become rope, and after 10-15 days, the solution containing thidiazuron is sprayed on the surface of its leaf for inducing the generation of flower buds.
Description
Technical field
The present invention relates to a kind of regulate and control method of blooming period of spring dendrobium stem, specifically, be meant a kind of method of utilizing plant growth regulator control blooming period of spring dendrobium stem.
Background technology
Florescence control is meant the method with the flowering time of manual method control flowers.
The spring stem of noble dendrobium is one of orchid kind of the tool ornamental value in the world, generally receives an acclaim.Dendrobium originates in the torrid zone and subtropical zone, mainly is distributed in Asia and Oceania.The cultivation of the spring stem of noble dendrobium needs the warm and humid climate condition, relative temperature condition of its derived need of blooming, therefore the florescence if advance to the Spring Festival or National Day, May Day etc., then need give an artificial low temperature treatment in the 3-5 month, warm 15-20 ℃ of this day, at temperature 10-15 ℃ of night, the time is 30-40 days (Huang Dinghua, flowers florescence control new technologies, Chinese agriculture publishing house, 1999).The florescence control of the spring stem of noble dendrobium and Moth orchid, hybrid cymbidium are the same, and very ripe method is arranged, and promptly are by refrigeration or set up the high mountain base, and this method is widely used in the world.But the subject matter that this method exists at present has two aspects: the one, because the natural temperature condition control flower that places one's entire reliance upon, therefore because the destabilizing factor of weather often causes flower forcing effect instability, Huang Ye, fallen leaves generally take place; The 2nd, the high energy consumption, high investment and the high production cost that utilize the method for high mountain base and artificial cooling to bring.
According to the hormone regulating and controlling theory of flowering of plant, utilize the various plants growth regulator, adopt and mix the method for using and successively using, regulation florescence effectively, to avoid strengthening competition capability because the drawback that low temperature control flower is brought reduces production costs.
The florescence chemical regulation technique has obtained application on various plants, comprise tulip, hyacinth, ivyleaf cyclamen, Doritis pulcherrima etc.; Growth regulator commonly used has gibberellin, 6-benzyl purine, paclobutrazol, chlormequat etc.But most at present control flower technology all are to adopt single plant growth regulator, though obtained success on some plants, for most plants, single plant growth regulator is difficult to obtain satisfied effect.As utilize 100 mg/litre 6-benzyl purines to induce the stem of noble dendrobium to bloom, though can shift to an earlier date the florescence, can not thoroughly break away from low temperature, the adverse consequences (Shao Limei, Meng Xiaoxiong, the plant growth regulator application manual that have caused that also the florescence shortens etc., Golden Shield publishing house, 1999, p73).
Stem of noble dendrobium florescence control research at present mainly concentrates on test tube flowering (Wang Guangyuan, 2. Xu Zhihong, Cai Defa, Cai Nanhai .1997, the stripped of dendrobium candidum blooms, Chinese science (C collects), 27 (3): 229-234), discover pre-the cultivation 15-20 days on the medium that contains ABA (abscisic acid) 0.5-1.5, when on the MS medium of transferring to additional 2 mg/litre 6-benzyl purines, continuing to cultivate subsequently, then become the flower frequency the highest, reach 82.8%.
Summary of the invention
Use the various plants growth regulator to mix and use or successively use, not only obviously improved the result of use of growth regulator, can also avoid the negative effect of using single growth regulator to cause effectively, be a development trend in the present plant growth regulator operation technique.
The objective of the invention is to the deficiency at the existing florescence control method of the spring stem of noble dendrobium, a kind of regulating and controlling blooming period of spring dendrobium stem new method is provided, its outstanding feature is: the florescence that can effectively control the spring stem of noble dendrobium; Compare with existing method and can reduce the flower forcing cost significantly, mainly show to need not to set up the high mountain base or utilize the power cooling at high temperature season; The flower forcing rate can not cause the variation of flower form and color and luster simultaneously up to more than 95%; And it is easy and simple to handle.
The object of the present invention is achieved like this:
(1) after the spring, stem of noble dendrobium pseudobulb blade launched fully, utilizes paclobutrazol and abscisic acid to mix to carry out foliage-spray or filling is executed, to accelerate the maturation of pseudobulb.The concentration of paclobutrazol is the 2-5 mg/litre in the mixed solution, and the concentration of abscisic acid is the 5-10 mg/litre; Spraying has water droplet to drip with the blade face to be as the criterion, and irritates to impose to there are flowing out at the bottom of the basin to be as the criterion.
(2) after step (1) is finished 10-15 days, use Thidiazuron solution to carry out foliage-spray or filling is executed, to promote the flower bud differentiation of the spring stem of noble dendrobium.The concentration of Thidiazuron solution is the 15-25 mg/litre; Spraying has water droplet to drip with the blade face to be as the criterion, and irritates to impose to there are flowing out at the bottom of the basin to be as the criterion.
Because the method that the present invention has adopted 3 plant growth materials to handle has in two steps promoted the maturation and the flower bud differentiation of spring stem of noble dendrobium pseudobulb, has delayed the aging of blade simultaneously, makes the duration of flowering blade remain green, has also improved the quality of the spring stem of noble dendrobium.
The present invention has following advantage and effect:
1. the experiment proved that, compare with existing flower-forcing method that this method (1), (2) two steps can reach identical flower forcing effect, and not be subjected to the influence of physioclimate uncertainty after finishing, flowering rate is stable; Yellow leaf and fallen leaves problem that this method has avoided the flower forcing process to cause have simultaneously obviously improved the ornamental value of potted flower; After this method flower forcing, flower form color and luster no change.
2. this method and existing method have relatively reduced the equipment and the operating cost of high mountain construction of base expense or refrigeration cool-down, and the production cost of potted flower is obviously reduced, and easy and simple to handle.
