Pobzala tomato, zowongolera zinayi za kukula kwa mbewuzi zimatha kulimbikitsa kukhazikika kwa zipatso za phwetekere ndikuletsa kusabala zipatso

Pobzala tomato, nthawi zambiri timakumana ndi vuto la kuchepa kwa zipatso komanso kusabala zipatso, pakadali pano, sitiyenera kudandaula nazo, ndipo titha kugwiritsa ntchito kuchuluka kwa owongolera kukula kwa mbewu kuti tithane ndi zovuta izi. .

1. Ethephon

Chimodzi ndicho kuletsa zopanda pake.Chifukwa cha kutentha kwambiri, chinyezi chambiri komanso kuchedwa kubzala kapena kutsatiridwa pakukula kwa mbande, kukula kwa mbande kumatha kuwongoleredwa ndi 300mg/kg ya masamba opopera a ethethylene pamene masamba 3, 1 pakati ndi masamba 5 enieni, kuti mbande zikhale zolimba, masamba. ndi zokhuthala, zimayambira zimakhala zolimba, mizu imakula, kukana kupsinjika kumakulitsidwa, ndipo zokolola zoyambirira zimawonjezeka.Kuyika kwake sikuyenera kukhala kwakukulu kapena kutsika kwambiri.

Yachiwiri ndi yakucha, pali njira zitatu:
(1) Kupaka kwa Peduncle: Pamene chipatsocho chiri choyera komanso chakucha, 300mg/kg ya ethephon imagwiritsidwa ntchito pa inflorescence ya gawo lachiwiri la peduncle, ndipo imatha kukhala yofiira komanso yakucha 3 ~ 5d.
(2) Kuphimba kwa zipatso: 400mg / kg ya ethephon imagwiritsidwa ntchito pa sepals ndi pafupi ndi zipatso zamaluwa a maluwa oyera oyera, ndipo zofiira zofiira ndi 6-8d kale.
(3) Zipatso zotulutsa: Zipatso za nthawi yakusintha kwamtundu zimasonkhanitsidwa ndikunyowetsedwa mu 2000-3000mg / kg yankho la ethethylene kwa 10 mpaka 30s, kenako ndikuchotsedwa ndikuyikidwa pa 25 ° C ndi chinyezi chachibale ndi 80% mpaka 85. % mpaka kucha, ndipo imatha kukhala yofiira pambuyo pa 4 mpaka 6d, ndipo iyenera kulembedwa m'nthawi yake, koma zipatso zomwe zimapsa siziwala kwambiri ngati zomwe zamera.

2.Gibberellik asidi

Ikhoza kulimbikitsa kukhazikitsidwa kwa zipatso.Nthawi yamaluwa, 10 ~ 50mg/kg kutsitsi maluwa kapena kuviika maluwa 1 nthawi, angateteze maluwa ndi zipatso, kulimbikitsa kukula kwa zipatso, bomba pogona zipatso.

3. Polybulobuzole

Angalepheretse pachabe.Kupopera 150mg/kg polybulobulozole pa mbande za phwetekere zomwe zimakhala ndi nthawi yayitali yosabereka kumatha kuletsa kukula kosabereka, kulimbikitsa kukula kwa uchembere, kumathandizira maluwa ndi kukhazikika kwa zipatso, kupititsa patsogolo tsiku lokolola, kukulitsa zokolola zoyamba ndi kutulutsa kwathunthu, ndikuchepetsa kwambiri kuchuluka kwa matenda ndi matenda. miliri koyambirira ndi matenda a virus.Tomato wa kukula kosalekeza anathiridwa ndi polybulobulozole kwa kanthaŵi kochepa ndipo amatha kuyambiranso kukula atangobzala, zomwe zinkathandiza kulimbikitsa tsinde ndi kukana matenda.

Ngati ndi kotheka, kuwongolera mwadzidzidzi kutha kuchitika m'chaka mbande ya phwetekere, mbande zikangowoneka ndipo mbande ziyenera kuyendetsedwa, 40mg/kg ndiyoyenera, ndipo ndendeyo imatha kuonjezeredwa moyenera, ndipo 75mg/kg ndiyoyenera.Nthawi yabwino yoletsa polybulobuzole pa ndende inayake ndi pafupifupi milungu itatu.Ngati mbande zisayang'anire kwambiri, 100mg/kg gibberellic acid imatha kupopera pamwamba pamasamba ndipo feteleza wa nayitrogeni atha kuwonjezeredwa kuti achepetse.

4.Chlormequat kloride

Angalepheretse pachabe.M'kati mwa kulima mbande ya phwetekere, nthawi zina chifukwa cha kutentha kwakunja kumakhala kokwera kwambiri, feteleza wambiri, kachulukidwe, kukula mwachangu komanso zifukwa zina zomwe zimayambitsidwa ndi mbande, kuwonjezera pa kubzala mbande, kuwongolera kuthirira, kulimbitsa mpweya wabwino, kukhala 3 ~ 4 masamba kwa masiku 7 asanabzale, ndi 250 ~ 500mg/kg yochepa kuthirira nthaka zamasamba, kuteteza kukula kwa.
Small mmera, pang'ono digiri wosabala, akhoza sprayed, kwa mmera tsamba ndi phesi pamwamba kwathunthu yunifolomu yokutidwa ndi zabwino m'malovu popanda ukuyenda digiri;Ngati mbande ndi zazikulu ndipo kuchuluka kwa wosabala ndi kolemetsa, kumatha kuwaza kapena kuthiridwa.

Nthawi zambiri 18 ~ 25 ℃, sankhani masiku oyambirira, mochedwa kapena mitambo kuti mugwiritse ntchito.Pambuyo pa ntchito, mpweya wabwino uyenera kuletsedwa, bedi lozizira liyenera kuphimbidwa ndi zenera, wowonjezera kutentha ayenera kutsekedwa pa shedi kapena kutseka zitseko ndi Windows, kusintha kutentha kwa mpweya ndikulimbikitsa kuyamwa kwa mankhwala amadzimadzi.Osamwetsa mkati mwa tsiku limodzi mutatha kugwiritsa ntchito kuti musachepetse mphamvu.
Sizingagwiritsidwe ntchito masana, ndipo zotsatira zimayamba 10d pambuyo kupopera mbewu mankhwalawa, ndipo zotsatira zake zikhoza kusungidwa kwa 20-30D.Ngati mbande sizikuoneka wosabala chodabwitsa, ndi bwino kuchitira yochepa mpunga, ngakhale mbande phwetekere yaitali, chiwerengero cha nthawi ntchito yochepa mpunga sayenera kukhala kwambiri, kuti zosaposa 2 nthawi ndi koyenera. .
