1. Paclobutrazol ndeye azole plant growth regulators, kuva biosynthetic inhibitors ye endogenous gibberellin.Iine mhedzisiro yekukanganisa kukura kwechirimwa uye kupfupisa kukwirira.Semuenzaniso, kushandiswa mupunga kunogona kuvandudza mashandiro eindole acetic acid oxidase, kuderedza chiyero cheiyo endogenous IAA mumhodzi yemupunga, kudzora zvakanyanya kukura kwepamusoro pembesa yemupunga, kukurudzira mashizha, kuita kuti mashizha asvibe, midzi system yakagadziridzwa, kuderedza pekugara uye kuwedzera huwandu hwekugadzira.The general control rate inosvika 30%;shizha rekusimudzira mwero i50% kusvika 100%, uye kuwedzera kugadzirwa kuri 35%.Kushandiswa mupeach, pear, citrus, maapuro nemimwe miti yemichero inogona kushandiswa kupfupisa muti.Geranium, poinsettia uye mamwe makwenzi ekushongedza, kana akabatwa ne paclobutrazol, vane chirimwa chemhando yavo chigadziriswe, ichipa yakakwirira yekushongedza kukosha.Kurimwa kwemuriwo wegreenhouse sematomatisi nekubatwa chibharo kunopa simba rembeu.
2. Kurimwa kwemupunga wanonoka kusimbaradza mbeu, panguva yeshizha/moyo mumwe, woomesa mvura yembesa mumunda woisa 100~300mg/L yePPA solution yekupfapfaidza uniform mu15kg/100m2.Dzora kukura kwakanyanya kwemuchina wekudyara madzinde emupunga.Isa 150 kg ye100 mg/L paclobutrazol mushonga wekunyisa 100kg yemhodzi yemupunga kwe36h.Isa kumera nekudyara uine makore 35d embeu uye uchidzora kureba kwembesa kusadarika 25cm.Kana ichishandiswa pakutonga kwebazi uye kudzivirira michero yemuti wemichero, inofanira kuitwa kazhinji mukupera kwematsutso kana muchirimo nemuti wega wega wemichero uchiiswa jekiseni ye500 mL ye300mg/L paclobutrazol mushonga mushonga, kana kuzviisa pasi pekudiridza yunifomu pamwe ne5. ~10cm nzvimbo yepasi pevhu yakatenderedza 1/2 korona radius.Isa 15% wettability poda 98g/100m2 kana zvakadaro.Isa iyo 100 m2 paclobutrazol nechinhu chinoshandiswa che 1.2 ~ 1.8 g / 100m2, uchikwanisa kupfupisa mharadzano yepasi yegorosi yechando uye kusimbisa tsinde.
3. Paclobutrazol inewo simba pakurwisa rice blast, cotton red rot, cereal smut, gorosi uye ngura yezvimwe zvirimwa pamwe chete ne powdery mildew, nezvimwewo. Inogonawo kushandiswa pakuchengetedza michero.Mukuwedzera, mukati meimwe chiyero, ine zvakare inhibitory mhedzisiro kune imwe chete, dicotyledonous sora.
4. Paclobutrazol inyanzvi yekukura kwemiti, inokwanisa kudzivisa kuumbwa kwegibberellin derivatives, kuderedza kupatsanurwa kwemiti yemiti uye kureba.Inogona kutorwa nyore nyore nemidzi, madzinde uye mashizha uye inoitiswa kuburikidza nexylem yechirimwa ine bactericidal effect.Iine basa rakakura pamiti yeGramineae, inokwanisa kuita kuti madzinde echirimwa ave mashanga mapfupi, kuderedza pekugara uye kuwedzera goho.
5. Iri ingano, kushanda kwakanyanya, yakaderera chepfu chirimwa kukura regulator ine wide-spectrum bactericidal effect.
6. Yakagadziriswa kushandiswa kwehuwandu hwezvinhu zvakasvibiswa: Pinacolone: 930kg / t, 1,2,4-triazole 540kg / t, chlorobenzyl chloride 960kg / t.
