1. Paclobutrazol belongs rau azole cog kev loj hlob regulators, ua biosynthetic inhibitors ntawm endogenous gibberellin.Nws muaj qhov cuam tshuam ntawm kev cuam tshuam cov nroj tsuag kev loj hlob thiab shortening lub suab.Piv txwv li, siv cov nplej tuaj yeem txhim kho cov haujlwm ntawm indole acetic acid oxidase, txo cov theem ntawm endogenous IAA hauv cov noob nplej, tswj kev loj hlob ntawm cov qoob loo sab saum toj, txhawb cov nplooj, ua rau nplooj ntsuab tsaus, hauv paus system tsim, txo qhov chaw nyob thiab nce tus nqi ntau lawm.Tus nqi tswj dav dav txog li 30%;nplooj nce qib tus nqi yog 50% mus rau 100%, thiab tus nqi ntau lawm yog 35%.Kev siv txiv duaj, txiv duaj, citrus, txiv apples thiab lwm yam txiv hmab txiv ntoo tuaj yeem siv los ua kom luv ntoo.Geranium, poinsettia thiab qee cov nroj tsuag ornamental, thaum kho nrog paclobutrazol, muaj lawv cov nroj tsuag hloov kho, muab cov txiaj ntsig zoo dua.Kev cog qoob loo ntawm tsev cog khoom zaub xws li txiv lws suav thiab rape ua rau cov nroj tsuag muaj zog.
2. Kev cog qoob loo lig tuaj yeem ntxiv dag zog rau cov yub, thaum lub sij hawm ib-nplooj / ib-lub siab theem, qhuav tawm cov yub cov dej hauv thaj teb thiab siv 100 ~ 300mg / L ntawm PPA tov rau cov tshuaj txau hauv 15kg / 100m2.Tswj qhov kev loj hlob ntau dhau ntawm lub tshuab hloov cov nplej nplej.Siv 150 kg ntawm 100 mg / L paclobutrazol tov rau soaking 100kg ntawm cov noob nplej rau 36h.Siv germination thiab sowing nrog lub hnub nyoog 35d yub thiab tswj cov yub qhov siab tsis siab tshaj 25cm.Thaum siv los tswj cov ceg ntoo thiab tiv thaiv cov txiv hmab txiv ntoo ntawm tsob ntoo txiv ntoo, feem ntau nws yuav tsum tau ua thaum lub caij nplooj zeeg lig lossis caij nplooj ntoos hlav nrog rau txhua tsob ntoo txiv ntoo uas raug txhaj tshuaj ntawm 500 mL ntawm 300mg / L paclobutrazol tshuaj tov, los yog raug rau cov dej sib xws raws li 5. ~ 10cm qhov chaw ntawm cov av nyob ib ncig ntawm 1/2 crown vojvoog.Siv 15% wettability hmoov 98g / 100m2 los yog li ntawd.Siv 100 m2 paclobutrazol nrog cov khoom xyaw nquag ntawm 1.2 ~ 1.8 g / 100m2, ua kom luv luv ntawm lub hauv paus kev sib tshuam ntawm lub caij ntuj no nplej thiab ntxiv dag zog rau qia.
3. Paclobutrazol kuj muaj txiaj ntsig tiv thaiv cov nplej blast, paj rwb liab rot, cereal smut, nplej thiab xeb ntawm lwm cov qoob loo nrog rau hmoov mildew, thiab lwm yam. Nws kuj siv tau rau cov txiv hmab txiv ntoo preservatives.Tsis tas li ntawd, nyob rau hauv ib qho nyiaj, nws kuj muaj cov nyhuv inhibitory tiv thaiv qee cov nroj tsuag dicotyledonous.
4. Paclobutrazol yog ib qho tshiab cog kev loj hlob regulator, muaj peev xwm inhibit qhov tsim ntawm gibberellin derivatives, txo cov cog cell faib thiab elongation.Nws tuaj yeem nqus tau yooj yim los ntawm cov hauv paus hniav, stems thiab nplooj thiab ua los ntawm xylem ntawm cov nroj tsuag nrog cov kab mob bactericidal.Nws muaj kev ua haujlwm ntau ntawm cov nroj tsuag Gramineae, muaj peev xwm ua kom cov nroj tsuag stems ua luv luv stalks, txo qhov chaw nyob thiab nce cov qoob loo.
5. Nws yog ib qho tshiab, kev ua haujlwm siab, tsis tshua muaj toxicity cog kev loj hlob regulator nrog broad-spectrum bactericidal nyhuv.
6. Tsau noj cov khoom siv raw: Pinacolone: 930kg/t, 1,2,4-triazole 540kg/t, chlorobenzyl chloride 960kg/t.
