Nzira dzekushandisa Ethephon pamiti yakasiyana-siyana yemichero

Ethephonine mhedzisiro yakawanda pahutano hwezvirimwa, zvakaita sekudzivisa kukura, kukurudzira kuumbwa kwemaruva nemaruva, kudzora bonde remaruva, kukonzera kusabereka kwenhengo, uye kukurudzira kuibva kwemichero. Panguva imwe chete, inokonzerawo maitiro akasiyana-siyana emakemikari mumuviri.

1. Kukurudzira Kutumbuka

Ethephoninogona kuwedzera basa re indole acetic acid oxidase mumiti, kunonotsa kugadzirwa kweIAA, kuderedza huwandu hweIAA mumiti, uye kumisa mabasa egibberellinsuye ma cytokinins. Izvi zvinobatsira kuzadzisa chinangwa chekudzivisa kukura kwemisoro yemapazi uye kukurudzira kusiyana kwemabukira emaruva. ​​Munguva yekusiyana kwemabukira emaruva, kana kukura kwezvirimwa kwakanyanya kana kusamira, zvinokanganisa zvakanyanya kusiyana kwemabukira emaruva. ​​Nekurapa neEthephon, zvinogona kudzivirira kukura kwemapazi matsva emiti yemichero kana kukonzera kuti matavi matsva aome uye afe, zvichiita kuti maitiro enguva dzose ekusiyana kwemabukira emaruva afambe.

Ethephon inoshandiswa pamiti yemichero yakaita se lychee, longan, apuro, mango, uye green plum, uye mhedzisiro yacho yakakosha zvikuru. Ethephon ine simba guru rekudzivirira kana kuuraya kukura kwemashizha e lychee ne longan munguva yechando. Kana ikashandiswa pamwe chete ne paclobutrazol nema amino acids, inogona kudzivirira kukura kwemashizha echando uye kukurudzira kuwedzera kwehukobvu hwemapazi. Kana ikasanganiswa nedzimwe nzira dzekutarisira zvirimwa kana nzira dzekurima, ethylenei ine simba rakanaka pakukurudzira kutumbuka kwemaapuro. Semuenzaniso, 40% Ethephon panguva yekuwanda kwe400 + 85% B9 panguva yekuwanda kwe400 + kurapwa kwe ring-barking pamaapuro eRed Fuji kunogona kudzivirira kukura kwemashizha matsva, kuvandudza kugona kwemuti kutumbuka, uye kuwedzera zvakanyanya huremu hwemuchero mumwe chete uye goho.

Kurapa ne ethephon pamiti yemichero yakaita semango, green plum, uye kiwi kunoderedza kukura kwemashizha matsva. Mushure mekurapwa kwemazuva manomwe kusvika gumi, maruva matsva e green plum ne kiwi anofa, zvichikurudzira kutumbuka kwemaruva, zvichiwedzera mwero wekubuda kwemichero, uye zvichiwedzera goho. Kurapa ne ethephon pa kiwi kunoita kuti michero ive yakatsetseka, kuderedzwa kukuru kwehuwandu hwemichero, uye ethylenei, ingave yakashandiswa yoga kana yakasanganiswa neB9 kana PP333, ine simba rekusimudzira kudonha kwemichero midiki, zvichideredza zvakanyanya kuomarara kwemichero uye kuva nemhedzisiro yekuibva. Mhedzisiro ye Ethephon pamabhanana yakasiyana neiri pamiti yemichero. Inogona kuwedzera huwandu hwema suckers anotorwa nemabhanana, kuderedza kuwanda kwemichero uye index yemichero, zvichikonzera kudzikira kwegoho.

II. Kudzivirira "Kukura Kwakakura"

Lychee neLongan zvese maruva akasanganiswa. Paanotanga kutumbuka muchirimo uye akasangana nekupisa kwakanyanya, chiitiko che "kukura zvakanyanya" chinowanzoitika. Kunyanya kuLongan, kana "kukura zvakanyanya" kukaitika, zvinokanganisa zvakanyanya kunaka kwemaruva uye goho. Nekurapa lychee neLongan neEthephon, kukura kwemashizha madiki pamitsipa yemaruva kunogona kudziviswa, uye maruva akachena anogona kugadzirwa. Kuburikidza nekutsvaga kwekutsvagisa paEthephon pa lychee yemashizha matema, zvakaonekwa kuti kuchena kwemashizha emaruva uye huwandu hwemichero pamitsipa imwe neimwe kwakawedzera. Kuwanda kwakakodzera kwe ethylene i200-250 mg/L. Pakupfapfaidza 250-300 mg/L Ethephon paLongan apo nhungirwa inokura 5-8 cm, zvinobatsira pakusiyanisa chimiro chemaruva uye zvinogona kudzivirira "kukura zvakanyanya", zvichikonzera maruva akajairwa.

Pakushandisa Ethephon kurapa mashizha madiki ari pamaruva, kana huwandu hwacho husina kukodzera, kazhinji hunokonzera kudonha kwemaruva. ​​Mukuyedza, zvakaonekwa kuti shanduko mukupisa nehunyoro panguva yekutumbuka kwe lychee ne longan dzaizokanganisa mashandiro eEthephon. Muchirimo chine tembiricha yakaderera nehunyoro hwakawanda, huwandu hweEthephon hwekudzivirira "kukura zvakanyanya" i250 mg/L; asi muchirimo chine tembiricha yakanyanya uye kusanaya kwemvura, huwandu hweEthephon hwekudzivirira "kukura zvakanyanya" i150 mg/L, izvo zvichiri kukonzera kudonha kwemaruva, uye mhedzisiro yacho yakafanana pa lychee ne longan.

III. Kukurudzira Kuibva

Hormone yeEthephon inogona kukurumidzisa kuora kwechlorophyll, kukurudzira kuumbwa kweanthocyanins, uye kukonzera ruvara rweganda remuchero, nokudaro ichikurumidzisa kuibva kwemuchero. Kupfapfaidza 200mg/L Ethephon hormone mazuva makumi mashanu mushure mekutumbuka kwemuchero we "Fisher's Smile" kunogona kuwedzera zvakanyanya kugona kwekugadzira anthocyanins, zvichiita kuti ruvara rwemuchero ruve nekukurumidza, nenzvimbo yekupenda ye61%. Hormone yeEthephon ine mhedzisiro yakati pakuvandudza ruvara nekuibva kwemacherry makuru, asi mhedzisiro yayo yakaderera zvishoma kana tichienzanisa nekurapa borax + gibberellin. Kurapa maEuropean sweet cherry ne30mg/L Ethephon hormone kunogona kuita kuti muchero ukure mazuva 1-2 apfuura. Kupfapfaidza 500-1000mg/L Ethephon hormone mavhiki maviri persimmons isati yaibva zvinogona kukurudzira kuibva kwemuchero, zvichiita kuti muchero ukure vhiki imwe yapfuura pasina kuderedza kunaka kwemuchero. Mushure mekurapwa ne ethylene hormone, hapana chakanyanya kuipa pa solid soluble, vitamin C, uye saizi yemichero, asi pane katsika kekuderedza titratable acid content.

IV. Kuchengeta nekuchengetedza

Pakutengeswa kwemichero mitsva, kuti iwedzere nguva yayo yekuichengeta, Ethephon inowanzo shandiswa kukurudzira kuibva kwemichero. Mushure mekunge michero yaiswa Ethephon, ruvara rwayo nekunaka kwayo zviri nani, asi huwandu hwekushandiswa kwayo hunofanira kucherechedzwa. Kana mango ikachengetwa muimba inotonhora pa25-28℃ mushure mekuiswa 200 kana 400mg/L Ethephon, hunhu hwemango hunokura zvakanaka. Zvisinei, kana ikaiswa 600mg/L Ethephon, chikamu chikuru chemuviri wemichero Ethephon chinobuda, zvichikonzera kuora kwenyama yemuchero.
