Gibberellic Acid GA3: Kukula-Kukulitsa Zodabwitsa Zasayansi Regulation Kuwirikiza Zokolola

Gibberellic Acid si feteleza wamba kapena mahomoni; m'malo mwake, ndi molekyulu yodziwika bwino yomwe imapezeka mkati mwazomera. Imawongolera ndendende moyo wonse wa mmera, kuyambira kumera mpaka kubereka zipatso. Deta ya labotale ikuwonetsa kuti mapangidwe a ufa wa crystalline wapamwamba kwambiri-oposa 85% chiyero-amasonyeza kusungunuka ndi kusungidwa kwa ntchito kuposa kukonzekera; izi zikutanthauza kuti galamu iliyonse ya yogwira pophika amatha yambitsa chiwerengero chachikulu cha zomera zomera.


Kusintha kwaukadaulo mu Kupanda mbewu
Zipatso zopanda mbewu zimalipira msika mpaka 30%; Komabe, njira zachikale zochotsera mbewu pamanja zimawononga mitengo yazipatso komanso yovutitsa. Mapangidwe a maselo a Gibberellic Acid mwanzeru amasokoneza njira zopangira mbewu. M'dera la Navel lalanje la Ganzhou, m'chigawo cha Jiangxi - pambuyo pa kuyesa kwazaka zitatu - kuchuluka kwa kusowa kwa mbewu m'magulu othandizidwa kumapitilira 91%, pomwe makulidwe a zipatso adakwera ndi 15%.

chinthu chapadera cha mapangidwe a ufa wa crystalline ndi khalidwe lake lomasulidwa pang'onopang'ono. Monga ukadaulo wa microencapsulation womwe umagwiritsidwa ntchito popereka mankhwala molondola, umatulutsa zomwe zimagwira ntchito pang'onopang'ono mkati mwazomera. Njirayi sikuti imangochepetsa chiwopsezo cha phytotoxicity chifukwa chochulukirachulukira komanso imakulitsa nthawi yomwe mankhwalawa akugwira ntchito. Malipoti owunikira kuchokera ku malo amakono a zaulimi adawonetsa kuti, masiku a 20 pambuyo pa ntchito imodzi, kuchuluka kwa Gibberellic Acid pa pedicels ya mphesa kunatsalira pamwamba pa chigawo chofunikira kuti chilimbikitse kukula.

Makamaka pakakhala nyengo yovuta, chowongolera chomera ichi chikuwonetsa phindu lalikulu pakukulitsa kulekerera kupsinjika. Chaka chatha, m’nyengo yotalikirapo ya chimvula ndi mvula mumtsinje wa Yangtze River Basin, kuchuluka kwa zipatso za mipesa yothiridwa mankhwala kunali 42% kuposa mipesa yosadulidwa. Izi zidathandiza alimi a zipatso ku Wuhu, m'chigawo cha Anhui, kuti apeze ndalama zochulukirapo ngakhale m'chaka chomwe chikuwonetsa kuchepa kwa zokolola. Monga momwe akatswiri a sayansi ya zamoyo amafotokozera: "Imatsegula njira zosungira mphamvu za zomera-mofanana ndi kusintha foni yam'manja kukhala 'yopulumutsa mphamvu'."

Chifukwa cha njira zopangira zachilengedwe, kuchuluka kwa zotsalira zazitsulo zolemera muzinthuzi kumangokhala gawo limodzi mwa magawo khumi a malire a dziko. Poyang'ana mwachisawawa ndi Zhejiang Provincial Agricultural Product Quality Testing Center, zipatso zonse zomwe zidapangidwa ndi mankhwalawa zidapambana mayeso 292 otsalira mankhwala ophera tizilombo. Khodi ya QR yosindikizidwa pamapaketi imalola kuti pakhale kutsata kwanthawi zonse kwa gulu lililonse lazogulitsa-chinthu chomwe chinapatsa Bambo Wang, woyang'anira wogula m'masitolo akuluakulu, kukhala ndi chidaliro kuti alembe zipatsozi ngati chopereka chamtengo wapatali mkati mwa mzere wake wamalonda apamwamba. Mayankho Okulitsa Mphatso Mwachindunji—Mapologalamu Ogwirizana a Mbeu Zosiyanasiyana:

Mphesa:Thirani masango ndi 5 ppm yankho pa nthawi ya pachimake chathunthu; bwerezani kugwiritsa ntchito pakadutsa masiku 10 kuti mutalikitse masango a zipatso ndikulimbikitsa mitundu yofananira.

Citrus:Utsi ndi yankho la 15 ppm pa nthawi ya zipatso zazing'ono; Kuti mupeze zotsatira zabwino, phatikizani mankhwalawa ndi girdling

Masamba Amasamba:Utsi ndi njira 3 ppm masiku 7 kukolola kuonjezera alumali moyo ndi 2-3 masiku.
