Tekinoroji yekushandisa mango:Dzivisa kukura kwemashizha
Kuisa midzi yevhu: Kana mango yakura kusvika pakureba 2cm, isa 25%paclobutrazolUpfu hwakanyorova huri mugomba remusana wemudzi wemango wega wega wakakura hunogona kudzivirira kukura kwemashizha matsva emango, kuderedza kudya zvinovaka muviri, kuwedzera huwandu hwemaruva, kupfupisa kureba kwemafundo, ruvara rwemashizha egirini rakasviba, kuwedzera huwandu hwechlorophyll, kuwedzera mashizha akaoma, uye kuwedzera kutonhora kwemashizha emaruva. Wedzera mwero wekugadzira michero uye goho zvakanyanya. Kushandiswa kwevhu kune mhedzisiro inoramba ichidzivirira nekuda kwekunwa midzi nguva dzose, uye kuchinja-chinja kwekukura kwemashizha matsva kudiki. Ine mhedzisiro yakakura yekudzivirira kukura kwemashizha matsva emango mugore rekutanga, mhedzisiro yakakura yekudzivirira kukura mugore rechipiri, uye mhedzisiro iri pakati nepakati mugore rechitatu. Kurapa kwakanyanya kwakaramba kune mhedzisiro yakasimba pamashizha mugore rechitatu. Kushandiswa kwevhu kuri nyore kuburitsa chiitiko chekudzivirira kwakanyanya, mhedzisiro yakasara yekushandiswa yakareba, uye gore rechipiri rinofanira kumiswa.
Kupfapfaidza nemashizha:Matavi matsva paakakura kusvika pakureba kwe30cm, nguva yekudzivirira inoshanda yaive ingangoita mazuva makumi maviri ne1000-1500mg /L paclobutrazol, uye ipapo kudzivirira kwacho kwaive pakati nepakati, uye simba rekukura kwematavi matsva rakachinja-chinja zvakanyanya.
Nzira yekushandisa trunk:Munguva yekukura kana kuti nguva yekurara, upfu hwepaclobutrazol hunonyoroveswa hunosanganiswa nemvura mukapu diki, uye hunozoiswa pamatavi ari pasi pematavi makuru nebhurashi diki, huwandu hwacho hwakafanana nehwekuiswa kwevhu.
Cherechedza:Kushandiswa kwepaclobutrazol mumiti yemango kunofanirwa kudzorwa zvakanyanya zvichienderana nenzvimbo yemuno uye mhando dzemango, kuitira kudzivirira kudziviswa kwakanyanya kwekukura kwemiti yepichisi, paclobutrazol haigone kushandiswa gore negore.
Paclobutrazol ine simba rinooneka pamiti yemichero. Bvunzo huru yekugadzirwa kwakaitwa pamiti yemango ine makore 4-6 ekuberekwa. Zvakabuda zvakaratidza kuti kurapwa kwacho kwakabuda maruva maawa 12-75 pamberi penguva yekudzora, uye huwandu hwemaruva hwaive hwakawanda, maruva acho aibuda zvakarongeka, uye nguva yekukohwa yaivewo kare kare nemazuva 14-59, nekuwedzera kukuru kwegoho uye mabhenefiti akanaka ehupfumi.
Paclobutrazol mushonga unoderedza chepfu shoma uye unoshanda zvikuru unoshandiswa zvakanyanya pari zvino. Unogona kudzivirira kugadzirwa kwegibberellin mumiti, nokudaro uchidzivisa kukura kwemiti uye uchikurudzira kutumbuka kwemaruva nemichero.
Zvakaitika zvinoratidza kuti miti yemango ine makore matatu kusvika mana, ivhu rega rega rine magiramu matanhatu ehuwandu hwekutengesa (chinhu chinoshanda 25%) chePaclobutrazol, inogona kudzivirira kukura kwematavi emango uye kukurudzira kutumbuka kwemaruva. MunaGunyana 1999, Aiwenmao neZihuamang vane makore matatu ekuberekwa vakarapwa ne6 g yehuwandu hwekutengesa hwepaclobutrazol, izvo zvakawedzera mwero wekuchekwa kwemiti ne80.7% kusvika 100% zvichienzaniswa nemushonga wekudzivirira (pasina paclobutrazol). Nzira yekuisa paclobutrazol ndeyekuvhura mugero usina kudzika mumutsetse wekudonhedza wemusoro wemuti, kunyungudutsa paclobutrazol mumvura uye kuiisa zvakaenzana mugomba woifukidza nevhu. Kana mamiriro ekunze akaoma mukati memwedzi mumwe mushure mekuisirwa, mvura inofanira kunyoroveswa zvakanaka kuti ivhu rirambe rakanyorova.
