Description

Cut gerbera flower is located liquid and using method thereof in advance
Technical field
The present invention relates to the cutflower preservation field, relate in particular to cut gerbera flower post-harvest fresh-keeping field.
Background technology
Flower industry is one of industry most active in world today's agricultural.At present, global fresh flower is consumed 50,000,000,000 dollars, and wherein cut-flower is 40,000,000,000 dollars.China has become the country of flower planting area maximum in the world, and flower planting area reached 430,000 hm in 2003 2, wherein, the cut-flower cultivated area reaches 2.4 ten thousand hm 2, produce 6700000000 of cut-flowers per year.
China's cut-flower is produced area and is accounted for 30% of world's gross area, but the volume of trade only accounts for 1.3% of world's total trade, this is except the reason of production aspect, the another one main cause is to adopt post-processing technology to fall behind, limit Chinese cut-flower outlet to a great extent, brought enormous economic loss for the cut-flower operator.
Flameray gerbera (Gerberajamesonii) claim African daisy again, Gerbera perennial evergreen herbaceous plant.Its flower is very large, and pattern enriches gorgeous, has developed in recent years and " four big cut-flowers " the fifth-largest cut-flower equally celebrated for their achievements.
The flameray gerbera scape is a herbaceous stem, and degree of lignification is low, adopts (" curved the neck ") phenomenon that is prone in back storing and the slotting process of bottle that fresh idea is sagging, scape is crooked and the ornamental value that reduces.The easy dewfall of container contents in adopting back storing and cause infection process; Container contents is easily generated heat, and makes commodity impaired.The situation that flameray gerbera loses ornamental value has following several:
1. insert the scape base portion that inserts in the process in the water at bottle and rot, be accompanied by rottenly, wilting appears in petal, and the flower neck occurs softening.
2. the scape base portion does not have putrefactive phenomenon, but bacterial reproduction in the conduit causes the conduit obstruction, and scape suction difficulty causes that petal wilting, flower neck soften etc.
3. tubular flower flower pesticide goes mouldy, spot appears in ligulate flower, further be expanded into whole flower rots.
At present, more about the research of cutflower preservation, but mainly concentrate on Chinese rose, carnation, sword lily etc., fewer to the fresh-keeping report of flameray gerbera.And mainly concentrate on fresh-keeping effect and the physiological effect of different chemical reagent in cut gerbera flower, being intended to provides theoretical foundation for the application of flameray gerbera preservation technique.As Ca 2+And K +(Zhang Yuping, 2004, different antistaling agents are to the fresh-keeping effect of cut gerbera flower.The subtropical plant science, 33 (1): 26-28), the antistaling agent that sucrose, oxine, citric acid and dipotassium hydrogen phosphate are formed (Li Fengying, 2002, antistaling agent is to the fresh-keeping effect and the physiological effect of cut gerbera flower.Guangxi Normal University's journal, 20 (3): 79-82), paclobutrazol (MET) (Luo Hongyi, 2003, contain the fresh-keeping effect of paclobutrazol antistaling agent to cut gerbera flower.Hubei agricultural science, (5): 80-81) all make the slotting life-span of bottle of flameray gerbera that certain increase is arranged.But comprehensive inadequately, and mostly be liquid for immersing in bottle, thereby effect is limited.This research be more than ten years cut gerbera flower is bloomed and the basis of old and feeble mechanism research on, after having grasped cut gerbera flower opening and senescence characteristics, determined the main component of antistaling agent, the concentration screening of the various compositions of antistaling agent is the optimum organization that obtains by orthogonal experiment.
Summary of the invention
At the problems referred to above that exist in the flameray gerbera post-harvest fresh-keeping, cause on the former gene basis of cut gerbera flower circulation loss in abundant research, the invention provides and a kind ofly can promote that flower is fully open, the pre-place liquid of kind of blooming period prolonging.
The invention provides a kind of cut gerbera flower and locate liquid in advance, it is characterized in that, locate liquid in advance and make by thiabendazole, citric acid, 6-benzyl purine, sodium thiosulfate, silver nitrate and TritonX are water-soluble in proportion.
