1. 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.
2. Ukulinywa kwerayisi esemva 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/100m2.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% ye-powder yokumanzisa i-98g / 100m2 okanye kunjalo.Faka isicelo se-paclobutrazol ye-100 m2 kunye nesithako esisebenzayo se-1.2 ~ 1.8 g / 100m2, ukwazi ukunciphisa isiseko se-intersection yengqolowa yasebusika kunye nokuqinisa isiqu.
3. 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.
4. I-Paclobutrazol iyinveli yokulawula ukukhula kwezityalo, ekwazi ukuvimbela ukubunjwa kwe-gibberellin derivatives, ukunciphisa ukuhlukana 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.
5. Yinoveli, ukusebenza kakuhle, ukulawulwa kokukhula kwesityalo esinetyhefu ephantsi enefuthe elibanzi le-bactericidal.
6. Ukusetyenziswa okuzinzileyo ubungakanani bezinto eziluhlaza: I-Pinacolone: 930kg / t, 1,2,4-triazole 540kg / t, i-chlorobenzyl chloride 960kg / t.
