1-MCP-the fresh flower (Agricultural product)transportation keep fresh significant breakthrough

　

      (In article the flowers and plants, fresh flower and agricultural product have same connotation, Forgives cannot write one by one, like speaks of  flower, also is suitable for agricultural product.)

     　December 1 in 2005，Mr. Lee goes to the B area No.65 of dounan(kunming china) to introduce circs of  use 1- MCP .This is also the feedback of the customer of Tounan that we hear for the first time. Mr. Lee said four  points:1.Before the customer often complained, after use 1- MCP,The customer complains with opinion to reduce obviously;2.Have once delay for two days on road ,According to the former circumstance,Receive scolding early with the blood pours the head,But the this time box used  1- MCP,The customer did not respond there;3.The time that goods were delay use 1- the MCP can avoid the fresh flowers drop petal,Very quick blet,wither,At the time of holidays and New Year,Many days that goods were delay can lower loss consumedly;4.The customer had no reflection to drop petal after receive the goods,Just spoke to flower head to drop.In a word,After using the 1-MCP,The customer seldom scolded,The opinion is little".Mr. Lee who is the customer speak very fascinating,The hearer change countenance and gape;A very small cloth put and can have the so big function incredibly in the fresh flowers box,Unimaginable!!

      Heihe - Russia's user of 1-MCP writes  like this:Quality of the fresh flower which Postpones arrival is better than this which arrival time is short.

The new Ethylene gas inhibitor 1-MCP(1-methylcyclopropene)，Now the moderate price cloth type is goes on the market,suits uses in the airtight fresh flower box,keep fresh result very obvious.At the same time,Uses in the cold storage and so on big space batch processing fresh flower's tablet A being possible also to sell.The report about 1- MCP on the Internet is quite a few.Did not discover the negative report still.A lot of agricultural product graduate schools all have the detailed report about 1-MCP of the usage and experiments.The website of our company:www.kmflower.com.cn,also also has many agricultural products (flowers, fruits and vegetables, fungus category) uses Ansip the contrast picture.The following elucidation and data about 1- MCP，all come from the Internet and related think factories,Not compile without basis,all has the basis to inquire.

The fresh flowers( agricultural product) usually have very big loss before arrives in the consumer hand ,The loss rate attains 10-30%.even higher.Estimate according to American Department of Agriculture,The flower farm crop lose to have 30% after adopt is the negative influence of the ethylene to result in . Most fresh cutflowers is  sensitive of ethylene.The disadvantageous influence of ethylene to flower is:leaf,bud,petal  shed off, the organ flection,Flower early decrepitude and leaf become yellow etc.To many flowers,Will produce the blossom speed to speed and blasted symptom if expose in the ethylene air.

The ethylene is a kind of gaseous hormone can promote the plant mature. At the plant organ decrepitude will release out from the inner part. Accelerate its decrepitude speed. This be inside source ethylene.In environment,Exist various ethylene source, Has the very tremendous influence to fresh flower's deterioration,This is the exogenous ethylene.The ethylene is main reason that causes fresh flowers faded quickly,Breathe to jump to become a fresh flowers especially(as corala rose)etc who is the impressionable species of ethylene.The fresh flowers produces a great deal of ethylene easily in concentrated store and carry,At the same time Discard-old newspaper,The flower twig squeezes and harm,Also has enlarged the ethylene production and accumulates in the airtight box,form the high density ethylene air,Thus affect to the life span of the plant very greatly,Reduces the market value.The rose flower petal easily Shed off from the pedicel and Drop the petal(The flower petal still is  fresh),Lead quickly fade mainly is also what ethylene cause.1-MCP is one kind of effect specially prominent ethylene inhibitor,The function mechanism is:The ethylene is one kind of plant hormone,When the plant organ enters the mature period,Ethylene will produce as the mature hormone,And unifies with the cell interior related ethylene acceptor,Activates a series of and the mature related physiological biochemistry response,Speeds up the organ to be senile and the death.With ethylene molecular structure similar l-MCP also may and these acceptor unions,But cannot cause the mature biochemistry reaction,Therefore,Employs 1-MCP before the plant endogenesis　ethylene release out,It can forestall with the related acceptor union,Blocked the ethylene and their union,To has avoided the negative influence which afterwards produces,Retarded the mature process,Achieved keep  fresh effect.

Why obvious Very fresh flower send to  the customer hand but the other side says not freshly，Falls the petal to be serious？An reality that have to admit and face：the fresh flower after Loads the box to transport on the way which quality drops seriously。Each flower shop because the quality loses on the way  every year usually is several thousand dollarses.The general flower shop cannot survive the main reason to belong to “ the fresh flower quality to drop, life is short,big loss",is not excessively.According to a our Hong Kong customer flower shop surveys,Before his shop each month fresh flower's loss in 7-8 thousand Yuan.Carries on maintains freshness processing(Including  huaxianzi antistaling agent use),We give his pledge are may reduce a half loss at least.

Why Kunming international auction market rose Is not easy to fall the petal, look like freshly.Sells the price is free transaction market two times?Because has used the STS silver thiosulfate.Why 550 Yuan/each litre/The bottle Antistaling agent (Namely silver thiosulfate STS processing fluid) so is expensive but very many companies send export the fresh flower not to dare not to use?Nothing but wants”bate ethylene,plays to prevents senile role".The fresh flower uses the silver thiosulfate in front of delivering goods (STS) to process can for lengthen life greatly(The general request is not lower than 4 hours time soaking),This already was not the secret. Used silver thiosulfate STS to overcome the ethylene influence already to become one kind of mutual recognition.

Since 1970,The resistance ethylene best weapon always is the silver thiosulfate(STS),To lengthens the fresh flower and potted flower's life the effect is remarkable,May solve the flowers and plants in the storage and transportation process,Because oneself poorly changes or the ethylene function which produces other fruits and vegetables and the germ but falls quality deterioration phenomenon and so on flower bud, fallen leaf, flowers accelerated aging and leaf blade become yellow .But along with time development,Includes the heavy metal silver ion have big  toxicity to mammal.Creates the environmental pollution question also changes day by day,Moreover the fresh flower soaks first in the STS liquor period of time after recovery.This process processing quite time-consuming and takes the trouble,At the same time also must prevent the plant which because the silver ion absorbs excessively causes to poison(Therefore the fresh flower cannot the long time soak in the STS processing liquor).But newest ethylene inhibitor 1-MCP Has effective solved these problems,This product non-toxic,Continues the response time to be short,Is one kind of ideal plant growth regulator.Australian scientist use 1-MCP in 20°C to processes 7-8 kind of homeland originally  produce cutflower,Then puts in the ethylene gas environment. With antitheses group compares，1-MCP obviously reduced flowers' falling off, Lengthened  the life after picked.They thought,1-MCP is the best substitute to STS that has the pollution to the environment.

The 1-MCP action mechanism and STS are same,All Is through forestalls with the plant ethylene acceptor to unify,Reduced ethylene acceptor  to prevents the function which the plant gets older.1-MCP was the recent years people studies discovery one kind of function effect most prominent new antistaling agent,Started to apply generally in developed country agricultural product production.

Because the fresh flower loses nutrient supply in box, environment bad, is easy  to produce the highly concentrated ethylene gas in airtight box, can cause fresh flower's flower petal to in curl, fade, fading and falls off, also creates etiolution, wilting, gets moldy and spoil with rotten situation. When flower,  vegetables, fruit was stewed is easy to change yellow, also is because the flowers , vegetables, fruit have reason of ethylene, therefore in the box the agricultural product quality drops seriously, once on the road occurs delays, the agricultural product thoroughly were finished. Therefore flower, fruit and vegetables in time packing and storage and transport must join the ethylene inhibitor.

The process of stores transportation to prevent the ethylene to produce is key of lengthens agricultural product  pick after life  (the note: This conclusion stems from many research institutes, Can check to manies on the Internet, after like China agricultural college facility agricultural engineering engineering research center ZhouQing "Flower pick keep fersh, Packing And Storage and transportation Technology"). New ethylene inhibitor 1 - MCP, has used in the fresh flower keep fresh and display the ethylene inhibitor the huge commercial potential. The test result showed, If in flower' in storing time greenhouse, the cold storage and the box uses 1-MCP,May cause the flower after the long time transportation,still maintained the good quality.

Majority fresh cutflower to be sensitive to the ethylene, when exposes the ethylene gas, may retard the calyx to open or  cause it not to be able to blossom. The overseas massive research indicated that, regarding the ethylene sensitive plant, before the ethylene release, 1--MCP application may lengthen the flower life and appreciate period greatly. Because 1-MCP can prevent the flowers and plant  the endogene and the extraneous source ethylene's function，Reduced flower brown and leaf blade etiolution，The suppression falls flower, fallen leaf，May affect on cutflower, potted flower, nursery stock,  cover plant and  view leaf plant,Causes it after the long-distance transport,Still could maintain a long goods time in various flower market and the retail shop,The 1-MCP application also has the tangible effect on the lily potted flower.

　1-MCP to the fresh flower,pot flower and grass flower keep fresh effect to obtain the full affirmation,Total to say,1-MCP may lengthen the fresh flower to pick after life to reach about equally 40%,High reaches above 300%,As one kind of new ethylene inhibitor,Is effective in the room temperature and the refrigeration condition,causes the fresh flower in vivo secretion to be stable, suppression endogene, extraneous source ethylene gas production,Kills extinguishes and suppresses the bacterium to multiply,effectively prevented the flower petal and the leaf blade withers, falls off,delays the calyx opening speed and can effectively repair the mechanical damage,which because transports on the way piles up one on top of another, the friction, the extrusion and so on causes.Dredges the drive pipe to promote plant absorbing water,Causes fresh cut flower to pass through long process and so on time refrigeration and long-distance transport,After arrives the destination still to maintain the leaf surface fresh green, the flower bud is erect.1-MCP may enhance fresh cut flower quality, lengthens fresh cut flower storage and the transportation time,The long-term use is advantageous in sets up the enterprise image,Stable customer relations,Increases fresh cut flower to make a profit with the market competitive power.

The 1-MCP use is simple,at the same time uses the ice bottle effect to be better. The 1-MCP may release the 1-MCP gas after absorbing water or in the moist space,

The fumigation fresh flower thus has the function,be applicable to most agricultural products,May use in any flowers and plants fruits and vegetables production and marketing profession,Including plants  peasant household, Transportation merchandising business, wholesale establishment, flower shop, mail order industry, supermarket industry and so on may use,Function peak for 4-6th hour,A processing is then effective,The use density is extremely low,The effective concentration only needs 0.2-1.0ppm（10^-9） in the airtight space.1-MCP extremely light thin, ice bottle to be very heavy not likely, ice bottle weight 1.4 kilograms, the transport expense bottle money is equal to 5 Yuan approximately.Goods only ice bottle transport expense take about 20 Yuan,But each goods( approximately heavy 60KG)put two piece of 1-MCP also on 3-4 Yuan,Not to an ice bottle money,Therefore the 1-MCP use cost is very low,As for the flower seller,Want to obtain the good market value,After must try to lengthen the fresh flower to pick the life.The 1-MCP processing is Taiwan and the Taiwan capital flower industry transportation and sale potted flower,fresh flower must keep fresh measure.Country's and so on Mexico, Costa Rica fresh cuts the flower, all started to use 1-MCP.

　　The 1-MCP application, can for reduce the fresh flower to lose and the excessively quickly quality drop on the way greatly, effectively reduces the transportation risk,Is the fresh flower the significant breakthrough which keep fresh in the way.

　　When ambient temperature > 13 ℃, the fumigation time is 4 - 6 hours, 1-MCP usually in 13 ℃ -24 ℃ between fumigation time must 4 hours at least then be effective. When ambient temperature < 13 ℃, should incremental dosage 1.5 times, or lengthens the fumigation time to 12 - 18 hours.The density is more big,temperature is more high, process time is more long,The effect is more obvious.When fresh flower transportation,Because lacks the direct-viewing mutual contrast,Used 1-MCP the fresh flower opposite party possibly have no what response after the customer hand in,The effect after customer  uses 1-MCP be possible to be difficult to make explicit description,This is not 1-MCP have no effect，After like Lily, Rose and so on use 1-MCP certain effects only can see when bottle put stage:The lilium, rose etc of use the 1- MCP conveyance . Flower life want to be long obviously.(In detail sees the web picture).The customer can obviously reduce complaint to fresh flower quality  affirmable.As for the fresh flower merchant，Every so often the customer had not reflected any possibly meant the customer is satisfied.

　Application method: fold of flower box,Breaks a seal takes out 1-MCP,The sack clamps with the clip,Put 1-MCP in the flower box two sides crevices place,a side  a piece(The suggestion takes out a piece first,Spurts wet with the spray can,Such 1-MCP release rate wants quick somewhat,Puts in one side the flower box,Seals one side the box lid first,The adhesive tape seals strictly,Rehandling in addition one side,1-MCP from takes out spurts wet to seals the box to complete generally in 1-4 minute,Is more quickly better,1-MCP spurts wet to the fresh flower effect which arrives regarding the same day to come well to be quicker.The attention seal good by causes the 1-MCP gas not to the revelation.At refrigerator to centralize processing use the A type 1- MCP

Centralize processing when the cold storage uses A 1-MCP,A piece uses in a cubic space.

　

attention:

1th.When the temperature excessively is low,Excessively is short on the road time,The 1-MC density excessively is low,The box seal is not good when has the effect speed to be able to reduce,The incremental dose and spurts wet 1-MCP to be able to obtain the improvement.Must maintain the certain process time,When the ambient temperature is low must lengthen the process time or enlarge the 1-MCP amount used.

2nd, like flower has beforehand processed by STS(silver thiosulfate), then the 1-MCP effect is not possibly obvious.

3rd,after the original package breaks a seal,Should use up as soon as possible in 1-3 day(B model).

4th,after uses 1-MCP certain effect like bottles put life to have to when put bottle can look comes out.

5th, 1-MCP product does not absorb water or puts in the completely dry air is cannot release the 1-MCP gas.

6th, is sick, rottenly, the mechanical damage fresh flower is easier to produce the ethylene, should promptly eliminate.

7th, the 1-MCP mechanism lies in reduced, the suppression ethylene acceptor aging responded that, does not have the invalid problem.
