Gusaba
Paclobutrazol ni iy'ubuyobozi bugenzura imikurire ya azole, kuba ibinyabuzima byangiza biosintetike ya endogenous gibberellin. Ifite ingaruka zo kubuza imikurire no kugabanya ikibuga. Kurugero, gukoreshwa mumuceri birashobora guteza imbere ibikorwa bya okiside ya acide acide indole, kugabanya urwego rwa IAA endogenous mu ngemwe z'umuceri, kugenzura cyane umuvuduko wo gukura hejuru y ingemwe z'umuceri, kuzamura amababi, gutuma amababi yijimye icyatsi, sisitemu yumuzi yateye imbere, kugabanya icumbi no kongera umusaruro. Igipimo rusange cyo kugenzura kigera kuri 30%; igipimo cyo kuzamura amababi ni 50% kugeza 100%, naho kongera umusaruro ni 35%. Gukoreshwa mumashaza, amapera, citrusi, pome nibindi biti byimbuto birashobora gukoreshwa mugabanya igiti. Geranium, poinsettia hamwe nibihuru bimwe na bimwe by'imitako, iyo bivuwe na paclobutrazol, bigira ubwoko bwibimera byahinduwe, bitanga agaciro keza cyane. Guhinga imboga rwatsi nka tomato no gufata kungufu bitanga ingaruka zikomeye zatewe.
Guhinga umuceri watinze birashobora gushimangira ingemwe, mugihe cyibabi rimwe / icyiciro cyumutima umwe, kuma amazi yingemwe mumurima hanyuma ugashyiraho 100 ~ 300mg / L yumuti wa PPA kugirango utere kimwe muri 15kg / 100m2. Kugenzura imikurire ikabije yimashini itera ingemwe z'umuceri. Koresha kg 150 ya 100 mg / L umuti wa paclobutrazol kugirango ushire 100 kg imbuto yumuceri kuri 36h. Koresha kumera no kubiba ufite imyaka 35d yo gutera no kugenzura uburebure bwingemwe butarenze 25cm. Iyo ikoreshejwe mugucunga amashami no kurinda imbuto igiti cyimbuto, igomba gukorwa mugihe cyizuba cyimpeshyi cyangwa mugihe cyizuba hamwe na buri giti cyimbuto zatewe inshinge 500 mL ya 300mg / L imiti ya paclobutrazol, cyangwa ikavomerwa hamwe kuri 5 ~ 10cm yubutaka bwubutaka buzengurutse ikamba rya 1/2. Koresha ifu ya wettability 15% 98g / 100m2cyangwa. Koresha metero 1002paclobutrazol hamwe nibikoresho bikora bya 1.2 ~ 1.8 g / 100m2, gushobora kugabanya ihuriro ryibanze ryingano yimbeho no gushimangira uruti.
Paclobutrazol kandi igira ingaruka mukurwanya umuceri, kubora ipamba itukura, ibinyampeke, ingano hamwe n'ingese y'ibindi bihingwa kimwe na powdery mildew, nibindi birashobora kandi gukoreshwa mukurinda imbuto. Mubyongeyeho, mubunini runaka, igira n'ingaruka zo kubuza kurwanya nyakatsi imwe, dicotyledonous.
Paclobutrazol ni igenzura rishya ryikura ryikimera, rishobora kubuza ishyirwaho ryibikomoka kuri gibberellin, kugabanya igabanywa ryimiterere yibimera no kuramba. Irashobora kwinjizwa byoroshye n'imizi, ibiti n'amababi kandi bigakorwa binyuze muri xylem y'igihingwa bifite ingaruka za bagiteri. Ifite ibikorwa byinshi ku bimera bya Gramineae, ibasha gutuma ibiti by ibihingwa bihinduka ibiti bigufi, kugabanya icumbi no kongera umusaruro.
Nibintu bishya, bikora neza, bigabanya ubumara buke bwibimera bikura hamwe na bagiteri yica bagiteri.
