Common makhalidwe anayi
Paclobutrazol, uniconazole, Mepiquat chloride, ndi Chlormequat onse ali m'gulu la olamulira kukula kwa zomera.Akagwiritsidwa ntchito, amatha kulamulira kukula kwa zomera, kulepheretsa kukula kwa zomera (kukula kwa pamwamba pa nthaka monga tsinde, masamba, nthambi, ndi zina zotero), komanso kulimbikitsa kukula kwa uchembere (zipatso, zimayambira, etc. Kukula kwa gawo la pansi) , kulepheretsa mbewu kukula mwamphamvu ndi miyendo, ndikuchita mbali yochepetsera mbewuyo, kufupikitsa ma internodes, ndikuwongolera kukana kupsinjika.
Zitha kupangitsa mbewu kukhala ndi maluwa ambiri, zipatso zambiri, zolima zambiri, nyemba zambiri, ndi nthambi zambiri, kuwonjezera kuchuluka kwa chlorophyll, kupititsa patsogolo luso la photosynthesis, komanso kukhala ndi zotsatira zabwino kwambiri zowongolera kukula ndi kuchulukitsa zokolola.Panthawi imodzimodziyo, zonse zinayi zimatha kutengeka ndi mizu ya zomera, zimayambira ndi masamba, koma kugwiritsa ntchito kwambiri kapena kuwonjezereka kwambiri kudzakhala ndi zotsatirapo zoipa pa kukula kwa zomera, choncho chisamaliro chapadera chiyenera kulipidwa.
Kusiyana kwa zinayi

1.Paclobutrazol
Paclobutrazol mosakayikira ndiyomwe imagwiritsidwa ntchito kwambiri, yogwiritsidwa ntchito kwambiri, komanso yogulitsa kukula kwa mbewu za triazole pamsika.Ndi inhibitor yopangidwa kuchokera ku endogenous gibberellins.Ikhoza kuchepetsa kukula kwa zomera, kulamulira ubwino wapamwamba wa tsinde, kulimbikitsa kusiyana kwa tillers ndi maluwa, kusunga maluwa ndi zipatso, kulimbikitsa kukula kwa mizu, kupititsa patsogolo mphamvu ya photosynthetic, ndi kuchepetsa kupsinjika maganizo.Zili ndi zotsatira zabwino kwambiri pa kugonana, ndi zina zotero.

Nthawi yomweyo, chifukwa idapangidwa koyamba ngati fungicide ya mbewu, imakhalanso ndi bactericidal ndi kupalira, ndipo imakhala ndi zotsatira zabwino kwambiri pa powdery mildew, fusarium wilt, anthracnose, rapeseed sclerotinia, etc.

Paclobutrazol angagwiritsidwe ntchito kwambiri m'munda mbewu, mbewu ndalama ndi zipatso mtengo mbewu, monga mpunga, tirigu, chimanga, kugwiririra, soya, thonje, chiponde, mbatata, apulo, citrus, chitumbuwa, mango, lychee, pichesi, peyala, fodya. , ndi zina.Zina mwa izo, mbewu za m'munda ndi zamalonda zimagwiritsidwa ntchito kwambiri kupopera mbewu mankhwalawa mu siteji ya mbande komanso nthawi yophukira komanso itatha.Mitengo yazipatso imagwiritsidwa ntchito kwambiri kuwongolera mawonekedwe a korona ndikuletsa kukula kwatsopano.Ikhoza kupopera, kupukuta kapena kuthiriridwa.Zimakhudza kwambiri mbande za rapeseed ndi mpunga.
Mawonekedwe: kusiyanasiyana kwa ntchito, kuwongolera bwino kwa kukula, kuchita bwino kwanthawi yayitali, zochitika zabwino zachilengedwe, zosavuta kuyambitsa zotsalira zadothi, zomwe zingakhudze kukula kwa mbewu yotsatira, ndipo sizoyenera kugwiritsidwa ntchito mosalekeza.Pamalo omwe Paclobutrazol amagwiritsidwa ntchito, ndi bwino kulima nthaka musanabzale mbewu ina.

2. uniconazole

Uniconazole tinganene kuti ndi njira yowonjezereka ya Paclobutrazol, ndipo ntchito yake ndi ntchito zake zimakhala zofanana ndi Paclobutrazol.
Komabe, chifukwa uniconazole ndi carbon iwiri chomangira, kwachilengedwenso ntchito ndi zotsatira za mankhwala ndi 6-10 nthawi ndi 4-10 kuposa Paclobutrazol motero.Zotsalira zake za nthaka ndi 1 / 5-1 / 3 yokha ya Paclobutrazol, ndipo mphamvu yake yamankhwala ndi Mlingo wowola mofulumira (Paclobutrazol imakhalabe m'nthaka kwa nthawi yoposa theka la chaka), ndipo zotsatira zake pa mbewu zotsatila ndi 1/5 yokha. Paclobutrazol.
Chifukwa chake, poyerekeza ndi Paclobutrazol, uniconazole imakhala ndi mphamvu yowongolera komanso yowononga mbewu ndipo ndiyotetezeka kugwiritsa ntchito.
Mawonekedwe: Kuchita bwino kwambiri, zotsalira zochepa, komanso chitetezo chachikulu.Pa nthawi yomweyi, chifukwa uniconazole ndi yamphamvu kwambiri, siyenera kugwiritsidwa ntchito pa mbande zamasamba ambiri (Mepiquat chloride ingagwiritsidwe ntchito), ndipo imatha kukhudza kukula kwa mbande.

3.Mepiquat kloride

Mepiquat chloride ndi mtundu watsopano wowongolera kukula kwa mbewu.Poyerekeza ndi Paclobutrazol ndi uniconazole, ndizochepa, zosakwiyitsa komanso zimakhala ndi chitetezo chokwanira.
Mepiquat chloride ingagwiritsidwe ntchito pazigawo zonse za mbewu, ngakhale m'magawo a mbande ndi maluwa pamene mbewu zimakhudzidwa kwambiri ndi mankhwala.Mepiquat chloride kwenikweni alibe zotsatira zoyipa ndipo samakonda phytotoxicity.Zinganenedwe kuti ndizotetezeka kwambiri pamsika.Wowongolera Kukula kwa Zomera.
Mawonekedwe: Mepiquat chloride ali ndi chitetezo chokwanira komanso nthawi yayitali ya alumali.Komabe, ngakhale ili ndi mphamvu yoletsa kukula, mphamvu yake ndi yochepa komanso yofooka, ndipo zotsatira zake zowongolera kukula ndizochepa.Makamaka kwa mbewu zomwe zimakula mwamphamvu, zimafunikira nthawi zambiri.Gwiritsani ntchito kangapo kuti mukwaniritse zomwe mukufuna.
4.Chlormequat

Chlormequat ndiwowongoleranso kukula kwa mbewu zomwe zimagwiritsidwa ntchito ndi alimi.Mulinso Paclobutrazol.Itha kugwiritsidwa ntchito kupopera mbewu mankhwalawa, kuthira ndi kuthira njere.Zili ndi zotsatira zabwino pakukula kwa kukula, kupititsa patsogolo maluwa, kulimbikitsa zipatso, kupewa malo ogona, kukana kuzizira, Zimakhala ndi zotsatira za kukana chilala, kukana mchere wa alkali ndi kulimbikitsa zokolola zamakutu.
Zomwe Zilipo: Mosiyana ndi Paclobutrazol, yomwe nthawi zambiri imagwiritsidwa ntchito pa mbande ndi kukula kwatsopano, Chlormequat imagwiritsidwa ntchito kwambiri pa nthawi ya maluwa ndi siteji ya zipatso, ndipo imagwiritsidwa ntchito pa mbewu zomwe zimakhala ndi nthawi yochepa.Komabe, kugwiritsa ntchito molakwika nthawi zambiri kumayambitsa kuchepa kwa mbewu.Kuphatikiza apo, Chlormequat itha kugwiritsidwa ntchito ndi feteleza wa urea ndi acidic, koma sangasakanizidwe ndi feteleza wamchere.Ndizoyenera ziwembu zokhala ndi chonde chokwanira komanso kukula bwino.Siyenera kugwiritsidwa ntchito pazigawo zomwe zili ndi chonde chochepa komanso kukula kofooka.
