Kukura kwechirimwaretarder chinhu chinodiwa pakudyara mbesa.Nekugadzirisa kukura kwezvinomera uye kukura kwembeu yezvirimwa, kunaka kuri nani uye goho repamusoro rinogona kuwanikwa.Zvinokonzera kukura kwemiti zvinowanzobatanidza paclobutrazol, uniconazole, peptidomimetics, chlormethalin, etc. Sezvo rudzi rutsva rwekukura kwemiti, prohexadione calcium yakagamuchira kupararira mumusika mumakore achangopfuura, uye nhamba yekunyoresa yakawedzerawo nokukurumidza.Zvadaro,paclobutrazol, niconazole, paroxamine, chlorhexidine, uye prohexadione calcium, ndeupi musiyano mukushandiswa kwemusika wezvigadzirwa izvi?
(1) Prohexadione calcium: Iri rudzi rutsva rwekudzosa kukura kwechirimwa.
Basa racho nderekuti rinogona kuvharidzira GA1 mu gibberellin, kupfupisa tsinde kureba kwezvirimwa, uye nokudaro kudzora kukura kwemakumbo emiti.Panguva imwecheteyo, haina mhedzisiro paGA4 iyo inodzora chirimwa maruva kusiyanisa uye kukura kwezviyo.
Prohexadione calcium yakatangwa muJapan muna 1994 se acyl cyclohexanedione kukura retardant.Kuwanikwa kweprohexadione calcium kwakasiyana neiyo yequaternary ammonium munyu (chameleon, mepinium), triazoles (paclobutrazol, alkene) Kukura kwezvirimwa zvinorembera zvakaita seoxazole) kwakagadzira munda mutsva wekunonoka-nhanho inhibition yegibberellin biosynthesis, uye yakatengeswa. uye inoshandiswa zvakanyanya muEurope neUnited States.Parizvino, prohexadione-calcium inonyanya kunetseka nemabhizimisi epamba, chikonzero chikuru ndechokuti kana ichienzaniswa ne triazole retarders, prohexadione-calcium haina chepfu yakasara kune zvinotenderera zvinomera, hapana kusvibiswa kune zvakatipoteredza, uye ine simba rakasimba.Mune ramangwana, inogona kutsiva triazole kukura retardants, uye ine yakafara tarisiro yekushandisa muminda, miti yemichero, maruva, Chinese mishonga yemishonga uye zvirimwa zvehupfumi.
(2) Paclobutrazol: Iyo inhibitor yemiti endogenous gibberellic acid.Iine mhedzisiro yekunonotsa kukura kwechirimwa, inhibiting mbesa kureba kwedzinde, kupfupisa internodes, kusimudzira tillering, kuwedzera chirimwa kusagadzikana kusagadzikana, kukurudzira maruva kusiyanisa uye kuwedzera goho.Paclobutrazol inokodzera zvirimwa zvakaita semupunga, gorosi, nzungu, miti yemichero, soya bhinzi, lawn, nezvimwewo, uye ine simba rinoshamisa rekudzora kukura.
Mamiriro ezvinhu epaclobutrazol: Kushandisa zvakanyanya kunogona kukonzera zvirimwa zviduku, midzi yakasvibiswa uye machubhu, mashizha akakomberedzwa, maruva asingatauri, kupera nguva isati yasvika mashizha ekare pasi, uye akamonyoroka uye mashizha maduku.Nekuda kwenguva yakareba yekushanda kwepaclobutrazol, kushandiswa kwakanyanya kucharamba kuri muvhu, uye kunokonzerawo phytotoxicity kune chirimwa chinotevera, zvichiita kuti pasave nembeu, kunonoka kubuda, kuderera kwembeu kubuda, uye kuremara kwembesa nezvimwe zviratidzo zvephytotoxic.
(3) Uniconazole: Iyo zvakare inhibitor yegibberellin.Iine mabasa ekudzora kukura kwezvinomera, kupfupisa internodes, diki zvirimwa, kusimudzira lateral bud kukura uye maruva kusiyanisa, uye kuwedzera kusagadzikana kusagadzikana.Nekuda kwekabhoni kaviri bond ye paclobutrazol, iyo biological kuita uye mhedzisiro yekurapa ndeye 6 kusvika 10 nguva uye 4 kusvika 10 nguva yakakwirira kupfuura iyo paclobutrazol, zvichiteerana, uye yakasara yakawanda muvhu inongova chikamu chechina cheiyo paclobutrazol, uye kushanda kwayo Chiyero chekuora chinokurumidza, uye kukanganisa kwezvirimwa zvinotevera ndeye 1/5 chete yepaclobutrazol.
Migumisiro ye uniconazole: kana yakashandiswa zvakanyanya, inokonzera phytotoxicity, inokonzera kupisa kwemiti, kusvava, kusakura zvakanaka, kuparara kwemashizha, mashizha anodonha, maruva anodonha, michero inodonha, kunonoka kukura, nezvimwewo, uye kushandiswa muchikamu chembesa yemiriwo. zvichakanganisawo kukura kwembesa , Izvo zvine chepfu kune hove uye hazvina kukodzera kushandiswa mumadziva ehove uye mamwe mapurazi emhuka dzemvura.
(4) Peptidamine (Mepinium): Iyo inhibitor yegibberellin.Inogona kuwedzera kuumbwa kwechlorophyll, chirimwa chakasimba, chinogona kunyudzwa kuburikidza nemashizha nemidzi yechirimwa, uye kuendeswa kuchirimwa chose, nekudaro ichivharira kureba kwesero uye kutonga kweapical, uye inogona zvakare kupfupisa internodes uye kugadzira chirimwa. mhando compact.Inogona kunonoka kukura kwechirimwa, kudzivirira chirimwa kuti chirege kukura, uye kunonoka kuiswa chisimbiso.Peptamine inogona kuvandudza kugadzikana kwesero membranes uye kuwedzera chirimwa kusagadzikana kuramba.Kuenzaniswa ne paclobutrazol uye uniconazole, ine milder mishonga yemishonga, haina kutsamwa, uye kuchengetedzwa kwepamusoro.Inogona kunyanya kushandiswa munguva dzose dzezvirimwa, kunyange mukukura kwembesa uye maruva apo zvirimwa zvinonzwa zvakanyanya kumishonga., uye hapana mhedzisiro yakaipa.
(5) Chlormetrodin: Inowana mhedzisiro yekudzora hyperactivity nekudzivisa synthesis ye endogenous gibberellin.Chlormetrodin ine kudzora mhedzisiro pakukura kwechirimwa, inoenzanisa kukura kwezvinomera uye kukura kwekubereka, inovandudza mukume uye chiyero chekumisikidza michero, uye inowedzera kushanda kwekurima.Kunonoka kurebesa masero, zvirimwa zvidiki, madzinde akasimba, uye kupfupisa internodes.
Yakasiyana ne paclobutrazol uye mepiperonium, paclobutrazol inowanzoshandiswa padanho rekudyara uye nhanho itsva yepfuti, uye ine mhedzisiro yakanaka panzungu, asi mhedzisiro pazvirimwa zvematsutso nechando zvinowanzoitika;Pazvirimwa zvipfupi, kushandiswa zvisina kunaka kweklorimethalin kunowanzokonzera kuderera kwezvirimwa uye phytotoxicity yakaoma kusunungura;mepiperinium ine hunyoro, uye inogona kusunungurwa nekupfapfaidza gibberellin kana kudiridza kuti iwedzere kubereka mushure me phytotoxicity.
