Paclobutrazol inowanzova poda, iyo inogona kuiswa mumuti kuburikidza nemidzi, mashizha uye mashizha emiti yemichero pasi pekuita kwemvura, uye inofanira kushandiswa panguva yekukura. Kazhinji pane nzira mbiri: kuparadzira ivhu uye kumwaya mashizha.
1. Akavigwa paclobutrazol
Nguva yakanaka ndeye apo nhungirwa yechipiri inotungira inenge 3-5 cm (apo yero ikaita girinhi kana kusati kwasvibira). Maererano nehukuru hwekorona, marudzi akasiyana-siyana, uye ivhu rakasiyana, zviyero zvakasiyana zvepaclobutrazol zvinoshandiswa.
Kazhinji, huwandu hwezvinhu zvepaclobutrazol hunoshandiswa pa square mita yekorona ye6-9 g, gomba kana mhete yemhete inovhurwa 30-40 cm mukati meiyo drip line kana 60-70 cm kubva pamusoro wemuti, uye yakafukidzwa nevhu. mushure mekudiridza. Kana mamiriro ekunze akaoma, Vhara ivhu mushure mekudiridza kwakakodzera.
Kushandiswa kwepaclobutrazol hakufaniri kunge kwakakurumidza kana kunonoka. Nguva yakatarwa inoenderana nekusiyana. Kunyanya kukurumidza kunotungamira nyore kupfuti pfupi uye kuremara; kunonoka, nhungirwa yechipiri inozotumirwa kunze kwechitatu nhungirwa isati yave yakasvibira zvachose. .
Ivhu rakasiyana richakanganisawo kushandiswa kwepaclobutrazol. Kazhinji, ivhu rejecha rine simba rekuvigwa riri nani pane ivhu revhu. Inokurudzirwa kushandisa paclobutrazol mune mamwe minda yemichero ine yakakwirira ivhu viscosity.
2. Foliar spraying paclobutrazol kudzora nhungirwa
Iyo paclobutrazol foliar spray ine mhedzisiro yakapfava kupfuura mimwe mishonga, uye inogona kunyatso kudzikisa kukuvadzwa kwemuti panguva yekudzora kupfura. Kazhinji, kana mashizha akashanduka akasvibira uye asina kukura zvakakwana, shandisa paclobutrazol 15% poda yakanyorova kwekutanga kwekutanga kwe600 nguva, uye zvishoma nezvishoma kuwedzera huwandu hwepaclobutrazol 15% yakanyorova poda kechipiri. Kudzora kupfura kamwe chete -10 mazuva. Mushure mekudzora nhungirwa 1-2 nguva, nhungirwa dzinotanga kukura. Ziva kuti nhungirwa hadzina kukura zvakakwana, kazhinji hadziwedzere ethephon, zvikasadaro zviri nyore kukonzera kudonha kwemashizha.
Apo mashizha anoshanduka akasvibirira, vamwe varimi vemichero vanoshandisa paclobutrazol kwekutanga kutonga kwepfuti. Chiyero chacho 1400 gramu ne 450 kg yemvura. Kudzora kwechipiri kwenhungirwa kwakangofanana nekutanga. Muyero wacho uchaderedzwa pashure kusvikira wasvika 400. Ne 250 ml ye ethephon. Paunotanga kudzora nhungirwa, zvakajairika mamiriro ekutonga kamwe chete mazuva manomwe ega ega, asi mazwi ezuva kana zvimwe zvinhu zvinofanirwa kutariswa. Mushure mekunge kugadzikana kwadzorwa, kunogona kudzorwa kamwe chete mazuva gumi.
