Pofuna kulimbikitsa kukhwima kwa zipatso zoyamba ndi kuonjezera kuchuluka kwa zinthu zouma, magulu otsatirawa a zowongolera zakukula kwa zomera zitha kusankhidwa.

1. Ethephon

Ntchito: Imatulutsa ethylene, imalimbikitsa mwachindunji kucha kwa zipatso, kukula kwa mitundu, ndi kufewetsa, potero kufupikitsa nthawi yakukhwima. Panthawi imodzimodziyo, imathandizira kusuntha kwa zinthu za photosynthetic kupita ku chipatso, mosalunjika kumapangitsa kuti zinthu zowuma ziziwunjikana.

Mbewu Zogwiritsidwa Ntchito: Zipatso za Climacteric monga nthochi, tomato, citrus, mango, loquats, etc.
Kuyikira kwa Ntchito:** Amagwiritsidwa ntchito ngati yankho la 0.1% -0.3% popopera zipatso kapena kuviika; chisamaliro chiyenera kutengedwa kuti tipewe phytotoxicity (mwachitsanzo, kutsika kwa zipatso kapena browning chifukwa cha ndende yochuluka).


2. Triacontanol

Ntchito: Imawonjezera photosynthesis, imachulukitsa kuchuluka kwa chlorophyll, komanso imathandizira ntchito ya amylase, motero imalimbikitsa kuwunjika kwa zinthu zowuma ndikupangitsa kuti mbewu zikhwime msanga.
Ntchito Njira: Foliar utsi pa ndende ya 0,5 ppm (i.e., 0.5 mg/L). Kuti mupeze zotsatira zabwino, gwiritsani ntchito kamodzi pa nthawi yoyamba ya maluwa komanso kamodzi pa nthawi ya pachimake.

3. Diethyl aminoethyl hexanoate (DA-6)

Ntchito: Imachulukitsa mitengo ya photosynthetic, imathandizira kagayidwe ka carbon ndi nayitrogeni, ndikuchedwa kumera; zimalimbikitsa kukhwima koyambirira, kuwonjezereka kwa zokolola, ndi kusintha kwabwino. Ndi yoyenera kugwiritsidwa ntchito panthawi yonse ya kukula ndipo imakhalabe yogwira mtima pansi pa kutentha kochepa.
Kuyikirako Kovomerezeka: 10–20 mg/L; ntchito kudzera kupopera mbewu mankhwalawa 2-3 zina pa achinyamata zipatso siteji ndi zipatso kukula siteji.

4. Brassinolide

Ntchito: Kumakulitsa kukula kwa maselo ndi kugawanika, kumawonjezera chiwerengero cha zipatso ndi kulemera kwa zipatso zamtundu uliwonse, komanso kumapangitsa kuti zipatso zifanane ndi mitundu; imathandizira kukhwima ndi 25% -40%.
Nthawi yogwiritsira ntchito: Ikani popopera mbewu mankhwalawa pakangoyamba maluwa, pamene zipatso zazing'ono zimakula, ndiponso zikamakula.


5. Forchlorfenuron (KT-30, CPPU)

Ntchito: Ngakhale imadziwika kwambiri polimbikitsa kukula kwa zipatso ndi kusunga maluwa ndi zipatso, imathanso kuthandizira kukhwima koyambirira komanso kuwongolera bwino polimbikitsa kugawanika kwa ma cell ndikuwongolera kagawidwe kazinthu zowuma. (Zindikirani: Kugwiritsa ntchito kwambiri kumatha kuchedwetsa kukula kwa mitundu.)
