Paclobutrazol inowanzova upfu, hunogona kunyudzwa mumuti kuburikidza nemidzi, madzinde nemashizha emiti yemichero pasi pemvura, uye hunofanira kushandiswa panguva yekukura. Kazhinji pane nzira mbiri: kuparadzira ivhu uye kupfapfaidza mashizha.
1. Paclobutrazol yakavigwa
Nguva yakanakisisa ndeye apo nhungirwa yechipiri inobuda inenge 3-5 cm (kana yero yashanduka kuita girini kana isati yasvibira). Zvichienderana nehukuru hwekorona, mhando dzakasiyana, uye ivhu rakasiyana, huwandu hwakasiyana hwepaclobutrazol hunoshandiswa.
Kazhinji, huwandu hwepaclobutrazol hunoiswa pa square meter imwe neimwe yekorona ye 6-9 g, goronga kana denderedzwa rinovhurwa 30-40 cm mukati memutsetse wekudonhedza kana 60-70 cm kubva pamusoro wemuti, uye rinofukidzwa nevhu mushure mekudiridza. Kana mamiriro ekunze akaoma, Vhara ivhu mushure mekudiridza zvakanaka.
Kushandiswa kwepaclobutrazol hakufanirwe kunge kuri nekukurumidza kana kunonoka. Nguva chaiyo inoenderana nemhando yacho. Kukurumidza kunotungamira nyore nyore kumapfundo mapfupi uye kuremara; kunonoka, mapfundo echipiri anotumirwa mapfundo echitatu asati anyatsova girini.
Ivhu rakasiyana rinozokanganisawo kushandiswa kwepaclobutrazol. Kazhinji, ivhu rejecha rine simba rekuviga kupfuura ivhu revhu. Zvinokurudzirwa kushandisa paclobutrazol mune mimwe minda yemichero ine ivhu rakakora.
2. Kupfapfaidza paclobutrazol nemashizha emiti kuti udzore nhungirwa
Mushonga wepaclobutrazol foliar une simba rakapfava kupfuura mimwe mishonga, uye unogona kuderedza kukuvara kwemuti panguva yekudzora nhungirwa. Kazhinji, kana mashizha ashanduka kuita girini uye asina kukura zvakakwana, shandisa paclobutrazol 15% wettable powder kekutanga kanenge ka600, uye wedzera zvishoma nezvishoma huwandu hwepaclobutrazol 15% wettable powder kechipiri. Dzora nhungirwa kamwe chete pamazuva gumi. Mushure mekudzora nhungirwa ka1-2, nhungirwa dzinotanga kukura. Cherechedza kuti nhungirwa hadzina kukura zvakakwana, kazhinji usawedzera ethephon, zvikasadaro zviri nyore kukonzera kudonha kwemashizha.
Kana mashizha ashanduka kuita magirini, vamwe varimi vemichero vanoshandisa paclobutrazol kuti vatange kudzora matavi. Chiyero chacho i1400 gramu ne450 kg yemvura. Chechipiri kudzora matavi kwakafanana nekwekutanga. Chiyero chacho chinoderedzwa mushure mezvo kusvika chasvika 400. Ne250 ml ye ethephon. Pakutanga kudzora matavi, mamiriro ezvinhu akajairika ndeekudzora kamwe chete mazuva manomwe ega ega, asi mazwi ezuva kana zvimwe zvinhu zvinofanirwa kufungwa nezvazvo. Mushure mekunge kugadzikana kwadzorwa, zvinogona kudzorwa kamwe chete mazuva gumi ega ega.
