Oyang'anira kukula kwa zomera amatha kusintha ndikuwongolera kukula kwa zomera, kusokoneza mwadala kuwonongeka komwe kumachitika chifukwa cha zinthu zoyipa ku zomera, kulimbikitsa kukula kwamphamvu ndikuwonjezera zokolola.
1. Sodium Nitrophenolate
Choyambitsa maselo a zomera, chimatha kulimbikitsa kumera, kuzika mizu, komanso kuchepetsa kufooka kwa zomera. Chimakhudza kwambiri kulima mbande zolimba komanso kupititsa patsogolo kupulumuka pambuyo pobzala. Ndipo chimatha kulimbikitsa zomera kuti zifulumizitse kagayidwe kachakudya, kuwonjezera zokolola, kupewa maluwa ndi zipatso kugwa, komanso kukonza ubwino wa zipatso. Ndi chinthu chogwirizana ndi feteleza, chomwe chingathandize kwambiri kugwiritsa ntchito feteleza.
* Masamba obiriwira: nyowetsani mbewu ndi madzi okwana 1.8% nthawi 6000 musanabzale, kapena thirani madzi okwana 0.7% nthawi 2000-3000 panthawi yophukira kuti zipatso zisamere bwino komanso kuti maluwa ndi zipatso zisagwe.
*Mpunga, tirigu ndi chimanga: Zilowetseni mbewu ndi madzi okwanira 1.8% nthawi 6000, kapena thirani madzi okwanira 1.8% nthawi 3000 kuyambira nthawi yophukira mpaka nthawi yophukira.
2. Kusagwira ntchito bwino kwa thupiasidi
Auxin yachilengedwe yomwe imapezeka paliponse m'zomera. Imathandizira kukulitsa nthambi za zomera, mphukira ndi mbande. Indoleacetic acid imatha kukulitsa kukula pang'onopang'ono, ndikuletsa kukula kapena kufa pang'onopang'ono. Komabe, imatha kugwira ntchito kuyambira mbande mpaka kukhwima. Ikagwiritsidwa ntchito pa siteji ya mbande, imatha kupanga mphamvu ya apical, ndipo ikagwiritsidwa ntchito pamasamba, imatha kuchedwetsa kukalamba kwa masamba ndikuletsa kutayika kwa masamba. Kugwiritsa ntchito nthawi ya maluwa kungathandize kukulitsa maluwa, kuyambitsa kukula kwa zipatso za parthenogenetic, ndikuchedwetsa kukhwima kwa zipatso.
*Phokoso ndi nkhaka: thirani ndi madzi ochulukirapo ka 7500-10000 a 0.11% pa nthawi yobzala mbande ndi nthawi yophukira.
*Mpunga, chimanga ndi soya zimathiridwa ndi madzi okwana 7500-10000 kuposa 0.11% nthawi ya mbande ndi maluwa.
3. Hydroxyne adenine
Ndi cytokinin yomwe ingathandize kugawa maselo a zomera, kulimbikitsa kupangika kwa chlorophyll, kufulumizitsa kagayidwe ka zomera ndi kupanga mapuloteni, kupangitsa zomera kukula mofulumira, kulimbikitsa kusiyana kwa maluwa ndi kupangika kwawo, komanso kulimbikitsa kukula msanga kwa mbewu. Imakhalanso ndi mphamvu yowonjezera kukana kwa zomera.
*Tirigu ndi mpunga: Zilowerereni mbewu ndi yankho la 0.0001% WP nthawi 1000 kwa maola 24 kenako zifesedwe. Itha kupopedwanso ndi madzi ochulukirapo ka 500-600 a ufa wonyowa wa 0.0001% panthawi yothira.
*Chimanga: Masamba 6 mpaka 8 akatsegulidwa ndi masamba 9 mpaka 10, gwiritsani ntchito 50 ml ya 0.01% water agent pa mu, ndikupopera 50 kg ya madzi kamodzi kuti muwongolere mphamvu ya photosynthesis.
*Soya: mu nthawi yolima, thirani ndi ufa wonyowa wa 0.0001% nthawi 500-600 wa madzi.
*Tomato, mbatata, kabichi waku China ndi chivwende zimathiridwa ndi madzi okwanira 0.0001% WP nthawi yomera.
4. Asidi wa Gibberellic
Mtundu wa gibberellin, womwe umalimbikitsa kutalika kwa tsinde, umayambitsa maluwa ndi zipatso, komanso umachedwetsa kukalamba kwa masamba. Kufunika kwa wowongolera sikovuta kwambiri, ndipo kumatha kuwonetsabe zotsatira za kukulitsa kupanga pamene kuchuluka kwake kuli kwakukulu.
*Nkhaka: Gwiritsani ntchito kupopera nthawi 300-600 za 3% EC nthawi ya maluwa kuti zipatso zimere bwino ndikuwonjezera kupanga, ndikupopera madzi nthawi 1000-3000 nthawi yokolola kuti masamba a vwende akhale atsopano.
*Selari ndi sipinachi: Thirani nthawi 1000-3000 za 3% EC masiku 20-25 musanayambe kukolola kuti mulimbikitse kukula kwa tsinde ndi masamba.
5. Naphthalene acetic acid
Ndi njira yowongolera kukula kwa mbewu. Imatha kukulitsa kugawikana kwa maselo ndi kukula, kuyambitsa mizu yozungulira, kuwonjezera zipatso, komanso kupewa kutayika kwa mbewu. Itha kugwiritsidwa ntchito mu tirigu ndi mpunga kuti iwonjezere kuphuka bwino, kuwonjezera kuchuluka kwa makutu, kulimbikitsa kudzaza kwa tirigu ndikuwonjezera zokolola.
*Tirigu: Zilowetseni mbewu ndi madzi okwana 2500 nthawi ya 5% kwa maola 10 mpaka 12, zichotseni, ndipo ziume bwino kuti zibzalidwe. Thirani madzi okwana 5% nthawi ya 2000 nthawi ya 5% musanalumikizane, ndipo thirani madzi okwana 1600 nthawi ya maluwa akamaphuka.
*Phokoso: Kupopera madzi nthawi 1500-2000 kungathandize kuti maluwa asagwe nthawi ya maluwa.
6. Indole butyric acid
Ndi mankhwala opangidwa ndi zomera omwe amalimbikitsa kugawikana kwa maselo ndi kukula, amalimbikitsa kupangika kwa mizu yozungulira, amawonjezera zipatso, komanso amasintha chiŵerengero cha maluwa achikazi ndi achimuna.
*Tomato, nkhaka, tsabola, biringanya, ndi zina zotero, thirani maluwa ndi zipatso ndi madzi okwana 1.2% kuwirikiza ka 50 kuti muwonjezere kumera kwa zipatso.
7. Triacontanol
Ndi njira yowongolera kukula kwa zomera mwachilengedwe yokhala ndi ntchito zosiyanasiyana. Imatha kuwonjezera kuchuluka kwa zinthu zouma, kuwonjezera kuchuluka kwa chlorophyll, kuwonjezera mphamvu ya photosynthesis, kuwonjezera mapangidwe a ma enzyme osiyanasiyana, kulimbikitsa kumera kwa zomera, mizu, kukula kwa tsinde ndi masamba ndi maluwa, komanso kupangitsa mbewu kukula msanga. Kupititsa patsogolo kuchuluka kwa mbewu, kuwonjezera kukana kupsinjika, ndikuwonjezera ubwino wa zinthu.
*Mpunga: Zilowetseni mbewu ndi 0.1% microemulsion nthawi 1000-2000 kwa masiku awiri kuti muwonjezere kumera ndi kukolola.
*Tirigu: Gwiritsani ntchito nthawi 2500~5000 za 0.1% microemulsion kupopera kawiri panthawi ya kukula kuti muwongolere kukula ndikuwonjezera zokolola.
