Abstract
A new use of sodium hydrosulphide for keeping cut flowers and cuttings fresh is the application of sodium hydrosulphide as the preservative of cut flowers and cuttings. The water solution of sodium hydrosulphide has the function of keeping the cut flowers of China rose, lily, rose, carnation, annual fleabane herb, liriopespicata, megranate, grayish purple polyphyll hibiscus, China loropetal and the like, and the cuttings of plants such as euonymus buneanus maxim, contorted bankow willow, peach tree and the like, fresh. The water solution can obviously delay the cut flowers to become brown and the leaves and bud from falling and prolong the observation life of the cut flowers for 5 to 9 days; therefore, the quality of the cut flowers is ensured, the flower petals are full, the color is bright and the pedicel and leaves stand upright; the immature cuttings can be delayed from etiolating and withering due to water loss. The preservative can be used for keeping the cut flowers and the cuttings of various plants fresh.
Description
One, technical field
The present invention relates to a kind of new purposes of known compound, exactly is the new purposes of a kind of NaHS (NaHS).
Two, background technology
In ornamental flower, all flowers, leaf, branch, fruit are bright in luster, or have fragrance and bennet is straight, branches and leaves are strong, but the colored class that water is supported after cutting all can be used as cut-flower.Along with the fast development of global economy and the improvement of people life style, the production scale of cut-flower and promoted extension are in continuous expansion.Since the seventies in last century, the fresh cut-flowers consumption demand is rapid growth just, and at present, its volume of trade has accounted for the over half of global flowers total trade.Cut-flower is one and has broken away from the self-existent living individual of parent, but still carrying out various metabolic activities though lost the supply of the moisture, mineral element, the basic element of cell division etc. of parent root based on respiration consumption, a series of physiological change takes place simultaneously in vivo, life is still continuing, as deal with improperly, be easy to quicken to wilt, shorten the storage and the bottle of cut-flower and insert the life-span, cause cut-flower to lose ornamental value, therefore, the old and feeble physiology of further investigation fresh cut-flowers, it is very important to the development of fresh cut-flowers industry to develop practicable preservation technique.
The fresh cut-flowers preservation technique has physical fresh-keeping and fresh chemically technology usually.The physical fresh-keeping technology is commonly used refrigeration, low O
2High CO
2The controlled atmosphere method of environment, irradiation treatment method.This class methods energy consumption is big, complicated operation, investment is big, cost is high, is not easy to generally promote.Chemical fresh-keeping method is the main flow of at present domestic and international cutflower preservation, mainly be under the prerequisite that does not cause environmental pollution, regulate cut-flower physiological metabolism function in basal part of stem chemical preservative on probation, as suppress microorganism breeding, prevent that conduit generation physiology in the cane from stopping up unobstructed moisture transportation, suppressing the generation of ethene in the plant corpus etc., delay to cut flower withering, prolong the slotting life-span of storage and bottle.The common chemical antistaling agent has sucrose, bactericide (as oxine etc.), ethylene inhibitor and antagonist (as silver nitrate and silver thiosulfate etc.), plant growth regulator (as IBA, GA
3, BA, B
9, CCC, CTA, NAA etc.), mineral salt (as potassium, calcium, ammonium, aluminium, cobalt, zinc salt etc.), organic acid (as citric acid, benzoic acid, ascorbic acid etc.) and many natural extract products etc., normally several compounds are by specific mass volume ratio compounding application, and the prescription of these mixtures just has obvious effect at a kind of or a few flowers mostly, thereby has limited its extensive use.Salicylic acid (SA) and nitric oxide (NO) are the broad spectrum type cut-flower found the in succession in recent years fresh-keeping monomers of transplanting, and have been widely used in the fresh-keeping field of various fruits and vegetables flowers.
Three, summary of the invention
The present invention aims to provide a kind of cut-flower of wide spectrum, the antistaling agent of transplanting, and technical problem to be solved is to select antistaling agent in compound known.
The applicant is according to cut-flower or transplant (cuttage plants shoots) inserted under the concrete conditions in the establishment of a specific crime self-sow and physiological metabolism characteristics at bottle and found NaHS is mixed with that the certain density aqueous solution can be used as cut-flower, the antistaling agent of transplanting use through the condition test of screening and system widely.
The alleged NaHS of the present invention promotes that cut-flower, the fresh-keeping new purposes of transplanting are exactly NaHS as the application of antistaling agent for cut-flower or as the application of the antistaling agent of transplanting.
Using method is that the fresh tangent plane with the cut-flower or the lower end of transplanting submerges in the certain density NaHS aqueous solution.Described tangent plane is the inclined-plane preferably, and described finite concentration is 0.05～0.8mmol/L, and preferred concentration is 0.1～0.5mmol/L.
Studies show that this antistaling agent can strengthen the water absorbing capacity of spray, increase the fresh weight of spray, the water balance that keeps cut-flower or transplant; Reduce film fat peroxide injury, keep the relatively stable of membrane structure, delay the brown stain of chlorophyllous degradation speed and otch, delay coming off of blade and petal, the yellow and the wilting dehydration of prematurity blade delay to transplant, make bennet, blade is tall and straight, flower is healthy and strong, full, bright gorgeous, cut-flower or the bottle of transplanting are inserted life-span comparison according to prolonging 5～9 days.
Result of study shows that also this antistaling agent NaHS aqueous solution is by hydrogen sulphide (H
2S) donor sodium hydrosulfide (NaHS) monomer is water-soluble formulated, and NaHS passes through slowly to discharge H in the aqueous solution
2S/HS
-, exercise its fresh-keeping function, and Na
+Not contribution of fresh-keeping effect to this antistaling agent.
Four, embodiment
Below provide non-limiting examples of the present invention.
Take by weighing a water NaHS (NaHSH
2O) add water preparation 0.2mmol/L concentration of aqueous solution.
With Chinese rose (Rosa chinensis Jacq), lily (Lilium L), rose, carnation (Dianthus caryophyllus L), annual fleabane herb (Erigeron annuus L.Pers.), the native tuber of dwarf lilyturf (Liriope spicata Thump Lour), see pomegranate (Punicagranatum L), the purple polyphyll rose of Sharon (Hibiscus syriacus L.f.amplissimus Gagnep.f.) of powder, safflower continue wood cut-flower and Bai Duwei thatches (Euonymus maackiiRupr.) such as (Loropetalum chinense (R.Br.) Oliver rubrum Yieh), dragon's paw willow (Salix matsudana Koidz.var.tortuosa Vilm.), inclined-plane at 45 is cut in the transplant lower end of branch such as peach, insertion contains in the vase of NaHS antistaling agent of 0.2mmol/L, submergence otch 2cm gets final product, every 48h changes a fresh-keeping liquid, and this fresh-keeping liquid is a matching while using.
