M'moyo watsiku ndi tsiku, ethephon nthawi zambiri imagwiritsidwa ntchito kupsa nthochi, tomato, persimmons ndi zipatso zina, koma ndi ntchito ziti za ethephon?Momwe mungagwiritsire ntchito bwino?
Ethephon, mofanana ethylene, makamaka timapitiriza luso ribonucleic asidi kaphatikizidwe mu maselo ndi kulimbikitsa kaphatikizidwe mapuloteni.M'dera la abscission la zomera, monga ma petioles, mapesi a zipatso, ndi maziko a petals, chifukwa cha kuwonjezeka kwa mapuloteni, kukonzanso kwa cellulase mu abscission wosanjikiza kumalimbikitsidwa, ndipo mapangidwe a abscission layer akulimbikitsidwa. , zomwe zimapangitsa kuti chiwalo chiwonongeke.
Ethephon ikhoza kupititsa patsogolo ntchito ya michere, komanso imatha kuyambitsa phosphatase ndi michere ina yokhudzana ndi kucha kwa zipatso pamene chipatso chacha kulimbikitsa kukhwima kwa zipatso.Ethephon ndi njira yabwino kwambiri yoyendetsera kukula kwa zomera.Molekyu ya ethephon imatha kutulutsa molekyulu ya ethylene, yomwe imakhala ndi zotsatira zolimbikitsa kukhwima kwa zipatso, kulimbikitsa kutuluka kwa bala, ndikuwongolera kusintha kwa jenda.
Zomwe zimagwiritsidwa ntchito kwambiri ndi ethephon ndi monga: kulimbikitsa kusiyana kwa maluwa achikazi, kulimbikitsa kukhwima kwa zipatso, kulimbikitsa kukula kwa mbewu, komanso kuswa mbewu.
Momwe mungagwiritsire ntchito ethephon ndi zotsatira zabwino?
1. Amagwiritsidwa ntchito kukhwimitsa thonje:
Ngati thonje ili ndi mphamvu zokwanira, pichesi ya autumn nthawi zambiri imacha ndi ethephon.Kugwiritsa ntchito ethephon ku thonje kumafuna kuti mabotolo ambiri a thonje m'munda wa thonje akhale ndi zaka zopitirira masiku 45, ndipo kutentha kwa tsiku ndi tsiku kuyenera kukhala pamwamba pa madigiri a 20 pogwiritsira ntchito ethephon.
Pakucha kwa thonje, 40% ethephon imagwiritsidwa ntchito makamaka kusungunula nthawi 300 ~ 500 zamadzimadzi, ndikupopera m'mawa kapena kutentha kwakukulu.Nthawi zambiri, ethephon ikagwiritsidwa ntchito ku thonje, imatha kufulumizitsa kuphulika kwa thonje, kuchepetsa kuphulika pambuyo pa chisanu, kumapangitsa kuti thonje likhale labwino, motero kuonjezera zokolola za thonje.
2. Amagwiritsidwa ntchito kugwa kwa jujube, hawthorn, azitona, ginkgo ndi zipatso zina:
Jujube: Kuyambira nthawi yakucha yoyera mpaka kupsa bwino kwa jujube, kapena masiku 7 mpaka 8 musanakolole, ndi mwambo kupopera ethephon.Ngati ntchito pokonza masiku candied, nthawi kupopera mbewu mankhwalawa akhoza moyenera patsogolo, ndi sprayed ethephon ndende ndi 0.0002%.~ 0.0003% ndi zabwino.Chifukwa peel ya jujube ndi yopyapyala kwambiri, ngati ndi zakudya zamitundumitundu, sizoyenera kugwiritsa ntchito ethephon kuti mugwetse.
Hawthorn: Nthawi zambiri, 0.0005% ~ 0.0008% yothetsera ethephon imapopera masiku 7 ~ 10 isanafike nthawi yokolola ya hawthorn.
Azitona: Nthawi zambiri, 0.0003% yankho la ethephon limapopera maolivi akatsala pang'ono kukhwima.
Zipatso zomwe zili pamwambazi zimatha kugwa pakatha masiku atatu kapena anayi mutapopera mbewu mankhwalawa, gwedezani nthambi zazikulu.
3. Za kucha phwetekere:
Nthawi zambiri, pali njira ziwiri zopsereza tomato ndi ethephon.Chimodzi ndi kuviika zipatso pambuyo pokolola.Kwa tomato omwe wakula koma osakhwima mu "nthawi yosintha mitundu", ikani mu njira ya ethephon yokhala ndi 0.001% ~ 0.002%., ndipo patatha masiku angapo ataunjika, tomato amasanduka wofiira ndi kukhwima.
Chachiwiri ndikujambula chipatso pamtengo wa phwetekere.Ikani 0.002% ~ 0.004% yankho la ethephon pa chipatso cha phwetekere mu "nthawi yosintha mitundu".Tomato wocha mwa njirayi amafanana ndi chipatso chokhwima mwachilengedwe.
4. Kuti nkhaka zikope maluwa:
Nthawi zambiri, pamene mbande za nkhaka zili ndi masamba enieni a 1 mpaka 3, njira ya ethephon yokhala ndi 0.0001% mpaka 0.0002% imapopera.Nthawi zambiri, imagwiritsidwa ntchito kamodzi kokha.
Kugwiritsiridwa ntchito kwa ethephon kumayambiriro kwa kusiyanitsa kwa maluwa a nkhaka kungasinthe chizolowezi cha maluwa, kuchititsa kuti pakhale maluwa aakazi ndi maluwa ochepa achimuna, potero kuwonjezera chiwerengero cha mavwende ndi mavwende.
5. Pakucha nthochi:
Kuti nthochi zipse ndi ethephon, 0.0005% ~ 0.001% ndende ya ethephon yankho nthawi zambiri imagwiritsidwa ntchito popangira kapena kupopera nthochi zisanu ndi ziwiri kapena zisanu ndi zitatu zakupsa.Kutentha kumafunika madigiri 20.Nthochi zomwe zimathandizidwa ndi ethephon zimatha kufewetsa mwachangu ndikusintha kukhala chikasu, astringency amatha, wowuma amachepa, ndipo kuchuluka kwa shuga kumawonjezeka.
