Zowongolera kukula kwa mbewu zimagwiritsidwa ntchito pa letesi

1. Kuthyola kugona kwa mbeu
Kutentha koyenera kuti mbeu za letesi zimere ndi 15-29 ℃. Pamwamba pa 25 ℃, kuthekera kwa kumera kumachepetsedwa kwambiri pansi pamikhalidwe yopanda kuwala. Mbewu zomwe zimaswa dormancy zimatha kupititsa patsogolo kumera kwawo kutentha kwambiri. Kutentha kwa nthaka kukafika pa 27 ℃, nthangala za letesi zimatha kukopeka kuti zigone.

Thiourea
Kuchiza ndi 0.2% Thiourea kunapangitsa kumera kwa 75%, pomwe kuwongolera kunali 7% yokha.

Gibberellic Acid GA3
Chithandizo cha Gibberellic Acid GA3 100mg/L chinapangitsa kuti 80% imere.

Kinetin
Kuviika njere ndi 100mg/L kinetin solution kwa mphindi zitatu kungathe kuthana ndi kugona pansi pa kutentha kwambiri. Kutentha kukafika 35 ℃, mphamvu ya kinetin imakhala yofunika kwambiri.

2: Letsani mabawuti
Daminozide
Letesi ikayamba kukula, tsitsani mbewuzo ndi 4000-8000mg/L Daminozide 2-3, kamodzi pa masiku 3-5, zomwe zimatha kuletsa kwambiri bolting, kukulitsa makulidwe a zimayambira, ndikuwongolera mtengo wamalonda.

Maleic hydrazide
Pakukula kwa mbande za letesi, mankhwala a Maleic hydrazide 100mg/L amathanso kulepheretsa kuphulika ndi maluwa.

3: Limbikitsani mabawuti
Gibberellic Acid GA3
Letesi ndiye tsamba lokhalo ndi masamba omwe amatha kulimbikitsa kulimba pansi pa nyengo yofunda komanso yamasiku ambiri chifukwa cha kutentha kwakukulu kwa kusiyanasiyana kwa maluwa. Kuchiza mbewu ndi usana wautali komanso kutentha kochepa kumathandizira kupanga maluwa, koma kusunga mbeu kumafuna nyengo yozizira. Mwachitsanzo, pakuyesa kwa chipinda chopangira nyengo, mkati mwa 10-25 ℃, zonse zamasiku ochepa komanso zazitali zimatha kuphulika ndi kuphuka; pansi pa 10-15 ℃ kapena pamwamba pa 25 ℃, zipatso sizikhala bwino ndipo nkhokwe yosungiramo mbeu imachepetsedwa; m'malo mwake, nkhokwe yosungiramo mbewu ndiyo yayikulu kwambiri pa 10-15 ℃. Nkovuta kusunga njere za letesi, ndipo kupopera mbewu mankhwalawa Gibberellic Acid GA3 kungathandize kuti letesiwo atsekedwe ndi kuchepetsa kuvunda.

Gibberellic Acid GA3
Pamene kabichi letesi ali 4-10 masamba, kupopera mbewu mankhwalawa 5-10mg/L Gibberellic Acid GA3 njira akhoza kulimbikitsa bolting ndi maluwa a kabichi letesi pamaso kabichi, ndi mbewu kukhwima masiku 15 m'mbuyomo, kuonjezera zokolola za mbewu.

4 Limbikitsani kukula
Gibberellic Acid GA3
Kutentha kwabwino kwa mbande za letesi ndi 16-20 ℃, ndipo kutentha kwabwino kwa mbande ndi 18-22 ℃. Ngati kutentha kupitirira 25 ℃, letesi amakula kwambiri. Kuwala mu greenhouses ndi amakhetsa m'nyengo yozizira ndi masika angakumane yachibadwa kukula kwa letesi. Madzi ayenera kuyendetsedwa nthawi zonse, ndipo madzi okwanira ayenera kuperekedwa panthawi yamutu. Kwa letesi wokhala ndi tsinde zodyedwa, pamene mbewuyo ili ndi masamba 10-15, ikani 10-40mg/L ya gibberellin.

Pambuyo pa chithandizo, kusiyanitsa kwa masamba a mtima kumafulumizitsa, kuchuluka kwa masamba kumawonjezeka, ndipo tsinde lanthete limafulumizitsa kuti litalike. Itha kukolola masiku 10 m'mbuyomu, ndikuwonjezera zokolola ndi 12% -44.8%. Letesi wamasamba amathandizidwa ndi 10mg/L wa gibberellin masiku 10-15 asanakolole, ndipo chomeracho chimakula mofulumira, chomwe chingawonjezere zokolola ndi 10% -15%. Mukathira ma gibberellins pa letesi, samalani ndi zomwe zimagwiritsidwa ntchito popewa kupopera mbewu mankhwalawa mopitilira muyeso, zomwe zimapangitsa kuti pakhale tsinde zowonda, kuchepetsa kulemera kwatsopano, kupangika pambuyo pake, komanso kutsika kwabwino.

M'pofunikanso kupewa kupopera mbewu mankhwalawa pamene mbande zing'onozing'ono kwambiri, mwinamwake zimayambira zidzakhala zowonda, bolting zidzachitika mofulumira, ndipo phindu lachuma lidzatayika.

DA-6 (Diethyl aminoethyl hexanoate)
Kupopera mbewu mankhwalawa letesi ndi 10mg/L DA-6 (Diethyl aminoethyl hexanoate) kungathenso kupangitsa mbande kukhala ndi mizu yotukuka ndi tsinde zokhuthala, nthawi zambiri kuchulukitsa zokolola ndi 25% -30%.

5. Kusunga mankhwala
6-Benzylaminopurine (6-BA)
Monga ndiwo zamasamba zambiri, letesi senescence ndi kusanduka chikasu kwa masamba pang'onopang'ono kukolola, kutsatiridwa ndi kupasuka kwapang'onopang'ono kwa minofu, kukhala yomamatira ndi kuvunda. Kupopera mbewu m'munda ndi 5-10mg/L 6-Benzylaminopurine (6-BA) musanakolole kungatalikitse nthawi yoti letesi akhale wobiriwira atapakidwa kwa masiku 3-5. Chithandizo cha 6-BA pambuyo pokolola chimachedwetsanso kuchira. Kupopera mbewu mankhwalawa ndi 2.5-10 mg/L 6-BA tsiku limodzi mutatha kukolola kumakhala ndi zotsatira zabwino. Ngati letesi poyamba kusungidwa pa 4 ° C kwa masiku 2-8, ndiye sprayed ndi 5 mg/L 6-BA pa masamba ndi kusungidwa pa 21 ° C, pambuyo 5 masiku mankhwala, 12.1% okha ulamuliro. akhoza kugulitsidwa, pamene 70% ya mankhwala akhoza kugulitsidwa.

Daminozide
Kumiza masamba ndi letesi zimayambira ndi 120 mg/L yankho la Daminozide kuli ndi chitetezo chabwino komanso kumatalikitsa nthawi yosungira.

Chlormequat Chloride (CCC)
Kumiza masamba ndi letesi zimayambira ndi 60 mg/L mankhwala a Chlormequat Chloride (CCC) amakhala ndi mphamvu yoteteza komanso amatalikitsa nthawi yosungira.
