Plant Growth Regulator Gibberellin Ga3 90% Tc
Gibberellin (GA) inokoshachirimwa kukura regulatormunzanga yanhasi.Kune akawanda marudzi egibberellins, ayo anowanzo shandiswa mukugadzirwa kwekurima uye anoita basa mukumera kwembeu, kuwedzera mashizha, kudzinde uye midzi elongation, uye maruva nemichero kukura.Basa rakakosha rekutonga, rinoshandiswa zvakanyanya mukutonga kwezuva nezuva kwezvirimwa.
Basa regibberellin
Basa rakakurumbira regibberellin ndere kukurumidza kurebesa kwemasero (gibberellin inogona kuwedzera zviri mukati auxin muzvirimwa, uye auxin inogadzirisa zvakananga kureba kwemasero), uye zvakare inosimudzira kupatsanurwa kwesero, izvo zvinogona kukurudzira kuwedzera kwesero.(asi haikonzerese acidization yemadziro esero), mukuwedzera,gibberellinzvakare ine physiological mhedzisiro ye inhibiting maturation, lateral bud dormancy, senescence, uye tuber kugadzirwa.Kurudzira kushandurwa kwemaltose (ita kuti kuumbwa kwe α? amylase);kukurudzira kukura kwezvinomera (hapana mhedzisiro pakukura kwemidzi, asi zvakanyanya kukurudzira kukura kwemazita nemashizha), kudzivirira kudonha kwenhengo uye kutyora dormancy, nezvimwe.
Maitiro ekushandisa gibberellin
1. Ichi chigadzirwa chinogona kusanganiswa nemishonga yezvipembenene uye inogona kuwirirana.Kana gibberellin inoshandiswa zvakanyanya, migumisiro yechirwere inogona kukonzera pokugara, saka inowanzogadziriswa ne metrophin.Cherechedza: Haikwanise kusanganiswa nezvinhu zvealkaline, asi inogona kusanganiswa ne acidic, isina kwakare fetiraiza nemishonga yezvipembenene, uye yakasanganiswa neurea kuwedzera kugadzirwa.
2. Nguva yekupfapfaidza ndeye 10:00 mangwanani uye mushure me3:00 masikati, kana yakanaya mukati memaawa mana mushure mekupfapfaidza, inofanira kumwazve.
3. Kuiswa kwechigadzirwa ichi kwakakwirira, tapota gadzirira maererano nedosage.Kana iyo yekumisikidza yakanyanya kukwirira, gumbo, kuchena kunozoonekwa kusvika raremara kana kusvava, uye mhedzisiro yacho haisi pachena kana iyo yakadzikira.Huwandu hwemvura inoshandiswa pamuriwo wemashizha inosiyana nekukura uye kusimba kwezvirimwa.Kazhinji, huwandu hwemvura inoshandiswa pa mu hausi pasi pe50 kg.
4. Iyo aqueous solution yegibberellin iri nyore kuora uye haifaniri kuchengetwa kwenguva yakareba.
5. Kushandiswa kwegibberellininogona kungoita basa rakanaka pasi pemamiriro efotereza nemvura, uye haigoni kutsiva fetereza.
