Paclobutrazol nigenzura ryimikurire yikimera hamwe na fungiside, igabanya imikurire yikimera, nanone bita inhibitor. Irashobora kongera ibirungo bya chlorophyll, proteyine na aside nucleic mu gihingwa, kugabanya ibirimo erythroxine na acide acetike ya indole, kongera irekurwa rya Ethylene, kongera ubukana bw’amacumbi, amapfa, ubukonje n’indwara, kongera umusaruro, kuzamura ireme no Kunoza imikorere myiza mu bukungu. Nuburozi buke kubantu, amatungo, inkoko n’amafi, kandi ikoreshwa ryabyo mu musaruro w’imboga bigira uruhare runini mu kongera umusaruro no kuzamura ireme.
Gukoresha paclobutrazol mubuhinzi
1. Guhinga ingemwe zikomeye
Iyo ingemwe z'ibijumba, melon n'izindi mboga zikura zifite amaguru, urashobora gutera kg 50-60 kg ya 200-400ppm y'amazi kuri hegitari kuri hegitari 2-4 kugirango wirinde ko habaho "ingemwe ndende" kandi ugatera ingemwe ngufi kandi zikomeye. . Kurugero, mugihe uhinga ingemwe zimbuto, gutera cyangwa kuvomera hamwe na 20 mg / L paclobutrazol yumuti kumababi 1 hamwe nicyiciro cyumutima 1 cyingemwe mumashanyarazi irashobora kuzamura ubwiza bwingemwe kandi bikabyara ingemwe ngufi kandi zikomeye.
Mugihe uzamura ingemwe za pepper, shyira amazi ya mg / L ya paclobutrazol 5 kugeza kuri 25 kuri stade yamababi ya 3 kugeza kuri 4 kugirango uhinge ingemwe zikomeye. Mugihe uzamura ingemwe zinyanya, shyiramo 10-50 mg / L ya paclobutrazol mugihe ingemwe ziri mukibabi cya 2-3 kugirango ziveho ibihingwa kandi wirinde gukura cyane.
Ku cyiciro cyibabi 3 cyinyanya zimpeshyi, shyiramo 50-100 mg / L paclobutrazol kugirango uhinge ingemwe zikomeye.
Mu guhinga ingemwe z'inyanya, amababi 3 n'umutima 1 batewe umuti wa mg / L 10 paclobutrazol.
Mugihe uzamura ingemwe z'ibiti, shyira 10-20 mg / L umuti wa paclobutrazol kumababi 5-6 kugirango ugabanye ingemwe kandi wirinde gukura cyane.
Mugihe uzamura ingemwe za keleti, shyira paclobutrazol 50 kugeza kuri 75 mg / L kumababi 2 numutima 1, bishobora gutuma ingemwe zikura kandi zigakura zikaba ingemwe ngufi kandi zikomeye.
2. Kugenzura imikurire ikabije
Mbere yo gutera, shira imizi ya pepeporo hamwe na 100 mg / L umuti wa paclobutrazol muminota 15 mbere yo gutera. Shira hamwe na 25 mg / L cyangwa 50 mg / L umuti wa paclobutrazol nyuma yiminsi 7 nyuma yo gutera; mugihe cyo gukura gukomeye cyane, koresha 100 ~ Gutera 200 mg / L amazi ya paclobutrazol birashobora kugera ku ngaruka ziterwa n’ibiti byangiza no gukumira imikurire y’amaguru.
Mugihe cyambere cyo gukura kwibishyimbo kibisi, gutera hamwe na mg / L ya paclobutrazol ya mg / L kugeza kuri 75 kugeza kuri 75 bishobora guteza imbere imiterere yabaturage, kuzamura fotosintezeza, no gukumira imikurire y’amaguru, bityo bigatuma umubare wa inflorescences ku giti nyamukuru wiyongeraho 5% kugeza 10% kandi igipimo cyo gushiraho pod hafi 20%.
Iyo edamame ifite amababi 5 kugeza kuri 6, uyiteho 50/75 mg / L ya paclobutrazol yamazi kugirango ibiti bikomere, bigabanye interode, biteze amashami, kandi bikure neza bitabaye legigi.
Iyo uburebure bwibihingwa bufite cm 40 kugeza kuri 50, shyira 300 mg / L amazi ya paclobutrazol kuva mu ntangiriro za Kanama kugeza mu ntangiriro za Nzeri, rimwe mu minsi 10, hanyuma utere inshuro 2 kugeza kuri 3 ubudasiba kugira ngo ukure imikurire.
Ingemwe z'inyanya zigomba guterwa umuti wa mg / L 25 paclobutrazol nyuma yiminsi 7 nyuma yo guterwa; gutera umuti wa 75 mg / L paclobutrazol nyuma yo gutinda ingemwe zirashobora gukumira imikurire yamaguru kandi bigatera ibimera.
Ku cyiciro cyibabi 3, gutera moss yo mu nyanja hamwe na 200 mg / L ya paclobutrazol y'amazi birashobora kugenzura imikurire ikabije kandi byongera umusaruro hafi 26%.
3. Kongera umusaruro
Mu cyiciro cyo gutera cyangwa gutera imbere kwimizi, imboga n’ibabi, gutera ibiro 50 bya 200 ~ 300ppm umuti wa paclobutrazol kuri hegitari imwe bishobora gutera umubyimba wamababi yimboga, kugabanya interode, ibihingwa bikomeye, kuzamura ubwiza, no kongera umusaruro. Kurugero, mbere yo gutoragura imyumbati, batera umuti wa mg / L 400 paclobutrazol kugirango wongere umusaruro hafi 20% kugeza kuri 25%.
Mu cyiciro cyibabi 4 cyimyumbati yumuhindo muri pariki, shyiramo 100 mg / L amazi ya paclobutrazol kugirango ugabanye interode, uhuze imiterere yikimera, kandi wongere ibiti. Kurwanya ifu ya mildew na mildew yamanutse byiyongera, kurwanya ubukonje biratera imbere, kandi igipimo cyimbuto cyiyongera. , umuvuduko wo kongera umusaruro ugera kuri 20%.
Ku cyiciro cya 3-4 cyibabi byabashinwa, gutera ibihingwa hamwe na 50-100 mg / L paclobutrazol umuti urashobora kwangiza ibihingwa no kongera imbuto hafi 10% -20%.
Iyo radis ifite amababi yukuri 3 kugeza kuri 4, uyasige hamwe na 45 mg / L paclobutrazol yumuti kugirango wongere imbaraga kandi ugabanye indwara; mugihe cyo gushinga imizi yinyama, uyiteho 100 mg / L paclobutrazol kugirango ubuze imikurire. Irabuza guhindagurika, ituma amababi y’igihingwa aba icyatsi, bigatuma amababi aba mugufi kandi agororotse, akongerera fotosintezeza, kandi agateza imbere gutwara ibicuruzwa bya fotosintezitike ku mizi y’inyama, bishobora kongera umusaruro ku 10% kugeza kuri 20%, bikarinda ingirabuzimafatizo, kandi bikazamura isoko ku isoko. .
Gutera edamame hamwe na 100/200 mg / L amazi ya paclobutrazol mugihe cyambere cyambere cyuzuye cyindabyo zirashobora kongera amashami meza, numero ya pod nuburemere bwa pod, kandi byongera umusaruro hafi 20%. Iyo imizabibu izamutse hejuru yikigega, shyira yam yam 200 mg / L ya paclobutrazol. Niba imikurire ikomeye cyane, uyite inshuro imwe muminsi 5 kugeza 7, hanyuma utere inshuro 2 kugeza kuri 3 ubudahwema kugirango ubuze imikurire yamababi namababi kandi uteze kumera kumashami kuruhande. Amababi yindabyo aratera imbere, ibijumba byiyongera, kandi umusaruro wiyongera hafi 10%.
4. Teza imbere ibisubizo hakiri kare
Ifumbire ya azote cyane ikoreshwa mumurima wimboga, cyangwa imboga zigicucu kandi urumuri ntiruhagije, cyangwa ubuhehere bwimboga mukarere karinzwe ni mwinshi nijoro, nibindi, akenshi bigatuma ibiti byimboga nibibabi bihinduka ndende, bigira ingaruka kumikurire yimyororokere no gushiraho imbuto. Urashobora gutera kg 50 ya 200ppm y'amazi kuri hegitari kugirango wirinde ibiti n'amababi byemewe, biteza imbere imyororokere no kwera hakiri kare. Mugihe cyo gushinga imizi yinyama, gutera 100-150 mg / L umuti wa paclobutrazol kumababi, litiro 30-40 kuri hegitari, birashobora kugenzura imikurire yibice byo hejuru kandi bigatera hypertrophyme yumuzi winyama. Witondere neza neza ibiyobyabwenge hamwe no gutera imiti imwe. Duteze imbere kwera imbuto. Nyuma yo kwera, shyira hamwe na 500 mg / L umuti wa paclobutrazol kugirango ubuze imikurire y'ibimera no guteza imbere imbuto.
Kwirinda
Igenzura cyane ingano nigihe cyimiti. Niba igihingwa cyose cyatewe, kugirango wongere ifatira ryamazi, ongeramo urugero rukwiye rwifu yo gukaraba idafite aho ibogamiye. Niba ibipimo ari binini cyane kandi kwibanda cyane bikaba byinshi, bigatuma imikurire yibihingwa ihagarikwa, urashobora kongera ikoreshwa ryifumbire mvaruganda, cyangwa ugakoresha gibberelline (92O) kugirango ukemure ikibazo. Koresha garama 0,5 kugeza kuri 1 kuri hegitari hanyuma utere ibiro 30 kugeza kuri 40 by'amazi.
