Isicelo
I-Paclobutrazol yeyokulawula ukukhula kwezityalo ze-azole, ibe yi-biosynthetic inhibitors ye-gibberellin engapheliyo. Ineziphumo zokuthintela ukukhula kwezityalo kunye nokunciphisa i-pitch. Umzekelo, ukusetyenziswa kwerayisi kunokuphucula umsebenzi we-indole acetic acid oxidase, ukunciphisa inqanaba le-IAA engapheliyo kwizithole zerayisi, ukulawula ngokubonakalayo izinga lokukhula komphezulu wezithole zerayisi, ukukhuthaza amagqabi, ukwenza amagqabi amnyama abe luhlaza, inkqubo yeengcambu iphuhlisiwe, inciphisa indawo yokulala kwaye yandise isixa semveliso. Izinga lolawulo jikelele lifikelela kwi-30%; izinga lokunyusa amagqabi yi-50% ukuya kwi-100%, kwaye izinga lokunyuka kwemveliso yi-35%. Ukusetyenziswa kwipesika, ipere, i-citrus, ama-apile kunye neminye imithi yeziqhamo ingasetyenziselwa ukwenza mfutshane umthi. I-Geranium, i-poinsettia kunye nezinye izihlahla zokuhlobisa, xa ziphathwa nge-paclobutrazol, uhlobo lwabo lwezityalo luhlengahlengiswe, lunike ixabiso eliphezulu lokuhlobisa. Ukulinywa kwemifuno ye-greenhouse efana neetumato kunye nodlwengulo kunika isiphumo esinamandla seedling.
Ukulinywa kwerayisi emva kwexesha kunokomeleza izithole, ngexesha legqabi elinye/inqanaba lentliziyo enye, yomise amanzi ezithole kwintsimi kwaye ufake i-100 ~ 300mg/L yesisombululo sePPA sokutshiza okufanayo kwi-15kg/100m.2. Lawula ukukhula okugqithisileyo komatshini wokutshintshwa kwezithole zerayisi. Faka i-150 kg ye-100 mg / L ye-paclobutrazol isisombululo sokucwina i-100kg yembewu yerayisi nge-36h. Gcoba ukuntshula nokuhlwayela nge-35d yobudala bezithole kwaye ulawule ubude bezithole bungabi ngaphezulu kwe-25cm. Xa isetyenziselwa ulawulo lwesebe kunye nokukhuselwa kweziqhamo zomthi weziqhamo, kufuneka ngokuqhelekileyo zenziwe ngasekupheleni kwekwindla okanye entwasahlobo kunye nomthi weziqhamo ngamnye ophantsi kwesitofu se-500 mL ye-300mg / L paclobutrazol isisombululo sechiza, okanye ukuthobela ukunkcenkceshela okufanayo kunye ne-5. ~10cm indawo yomphezulu womhlaba ojikeleze i-1/2 yeradiyasi yesithsaba. Faka i-15% yomgubo wokumanzisa 98g/100m2okanye njalo. Faka i-100 m2i-paclobutrazol enezithako ezisebenzayo ze-1.2 ~ 1.8 g / 100m2, ukukwazi ukunciphisa isiseko se-intersection yengqolowa yasebusika kunye nokuqinisa isiqu.
I-Paclobutrazol nayo inefuthe kwi-rice blast, i-cotton red rot, i-cereal smut, ingqolowa kunye nerusi yezinye izityalo kunye ne-powdery mildew, njl. Ukongeza, phakathi komyinge othile, ikwanefuthe elithintelayo ngokuchasene nokhula olunye, olune-dicotyledonous.
I-Paclobutrazol iyinveli yokulawula ukukhula kwezityalo, ekwazi ukuvimbela ukubunjwa kwe-gibberellin derivatives, ukunciphisa ukwahlukana kwesityalo kunye nokwandisa. Iyakwazi ukufunxwa lula ngeengcambu, iziqu kunye namagqabi kwaye iqhutywe nge-xylem yesityalo kunye nefuthe le-bactericidal. Inomsebenzi omninzi kwizityalo zeGramineae, ikwazi ukwenza izikhondo zesityalo zibe ziindiza ezimfutshane, ukunciphisa indawo yokulala kunye nokwandisa isivuno.
Yinoveli, ukusebenza kakuhle okuphezulu, ukulawulwa kokukhula kwezityalo okunetyhefu ephantsi enefuthe elibanzi le-bactericidal.
