Gibberellic acid ndi wapamwamba kwambiriWowongolera Kukula kwa Zomera,ndiwoyera crystalline ufa.Imatha kusungunuka mu mowa, acetone, ethyl acetate, sodium bicarbonate solution ndi pH6.2 phosphate buffer, zovuta kusungunuka m'madzi ndi ether.Gibberellic acid angagwiritsidwe ntchito mosamala mu zodzoladzola.Itha kulimbikitsa kukula kwa mbewu, kukhwima msanga, kuwongolera bwino ndikuwonjezera zokolola.Kugwiritsa ntchito pakhungu kungalepheretse kupanga melanin, kotero kuti mawanga amtundu wa nevus amakhala ngati mawanga akuda ndi kuyera khungu.

Kugwiritsa ntchito

1. Limbikitsani mapangidwe a zipatso kapena zipatso zopanda mbewu.Pa nthawi ya maluwa a nkhaka, ikani mankhwala a 50-100mg/kg kamodzi kuti zipatso ziwonjezeke.Pambuyo pa masiku 7-10 a maluwa a mphesa, duwa la mphesa lonunkhira limapopera madzi a 200-500mg/kg kamodzi kulimbikitsa mapangidwe a zipatso zopanda mbewu.

2. Limbikitsani kukula kopatsa thanzi kwa udzu winawake.Uza masamba ndi 50-100mg/kg yankho kamodzi masabata awiri asanakolole;Kupopera mbewu mankhwalawa masamba a sipinachi ka 1-2 kutsala milungu itatu kukolola kungathe kuwonjezera tsinde ndi masamba.

3. Kuswa dormancy ndi kulimbikitsa kumera mbatata.Zilowerereni ma tubers mu njira ya 0.5-1mg/kg kwa mphindi 30 musanabzale;Kuviika njere za balere ndi 1mg/kg ya mankhwala musanabzale kungathandize kumera.

4. Kuletsa kukalamba ndi kuteteza: zilowerere m'munsi mwa adyo sprouts ndi 50mg/kg yankho kwa mphindi 10-30, uzani zipatso ndi 5-15mg/kg solution kamodzi pa gawo la zipatso zobiriwira za citrus, zilowerereni zipatso ndi 10mg/ kg yankho mukatha kukolola nthochi, ndi kupopera zipatso ndi madzi a 10-50mg/kg musanakolole nkhaka ndi mavwende, zonse zomwe zingathe kuteteza.

5. Pa vernalization siteji ya maluwa chrysanthemums, kupopera mbewu mankhwalawa ndi 1000mg/kg wa mankhwala njira, ndi pa Mphukira siteji ya Cyclamen persicum, kupopera mbewu mankhwalawa maluwa ndi 1-5mg/kg wa mankhwala akhoza kulimbikitsa maluwa.

6. Kupititsa patsogolo kachulukidwe ka mbeu pa ulimi wa mpunga wa Hybrid nthawi zambiri kumayamba pamene kholo lachikazi latsala pang'ono kufika 15%, ndipo amamwa mankhwala amadzimadzi a 25-55mg/kg ka 1-3 kumapeto kwa mutu wa 25%.Choyamba ntchito otsika ndende, ndiye ntchito mkulu ndende.

Kusamalitsa

1. Gibberellic acid imakhala ndi kusungunuka kwamadzi kochepa.Musanagwiritse ntchito, sungunulani ndi mowa pang'ono kapena Baijiu, kenaka yikani madzi kuti muchepetse ndende yofunikira.

2. Mbewu zothiridwa ndi gibberellic acid zimachulukitsa mbewu zosabereka, choncho sikoyenera kugwiritsa ntchito mankhwala ophera tizilombo m'munda.
