Plant Growth Regulators Anoratidza Kushanda Kwakakosha muPamusoro Tembiricha Yezhizha Nzvimbo.
Mamiriro ezvinhu akashata anowanzoitika muzhizha-akadai sekupisa kwakanyanya, kupenya kwezuva, uye kusanaya kwemvura-kazhinji zvinotungamira mukukura kwakanyanya kwezvinomera (etiolation) uye kusashanda zvakanaka kwemuviri muzvirimwa. Plant growth regulators anogadzirisa nyaya idzi nekugadzirisa chiyero che endogenous mahormone; izvi zvinowedzera kushivirira kwekushushikana, zvinodzivirira kukura kwakapararira, uye zvinokurudzira kukura kwekubereka, nokudaro kudzikamisa zvose goho uye kunaka.
1. Kudzora Kukura Kwakanyanyisa uye Kudzivirira Etiolation
Mumamiriro ekunze ekupisa, kunyorova kwezhizha, zvirimwa (sechibage, donje, uye gorosi) zvinowanzoita stem elongation, internode stretching, uye kuwedzera kwengozi yekugara (kudonha). Kushandisa zvinoderedza kukura—zvakadai seMepiquat chloride, Paclobutrazol (Paclo), kana kuti Chlormequat chloride—padanho rino zvinobudirira inhibits gibberellin synthesis uye kunonotsa kureba kwesero. Izvi zvinopfupisa mainternodes, zvichikonzera kuti zvidyarwa zvakasimba, zvakati wandei zvine midzi yakanyatsogadzirwa, nekudaro zvichivandudza zvakanyanya kuramba kwavo pekugara.
Kudzidzira Kushandisa Kwakakosha: Kutora donje semuenzaniso, kutonga kwemakemikari kunofanirwa kutangwa kana kuwedzera kwezuva nezuva kwedzinde guru kunodarika 0.8 cm. Isa 0.5–2 magiramu e98% Mepiquat chloride pa *mu* (approx. 0.067 hectares) munguva dzemanheru kana kuti mumazuva ekunaya kwemvura, uchiona kuti nzvimbo dziri kukura dzakavharika uye mashizha ekumusoro manyoro.
2. Kuwedzera Kushivirira kune Kupisa Kwepamusoro uye Kusanaya kwemvura
Tembiricha yakakwira uye kusanaya kwemvura kunogona kuwedzera kukura kwechirimwa, kuderedza mashandiro ephotosynthetic, uye kukonzeresa kusimba kwekukasika uye kusvava. Kushandiswa kwemaregulator akadai seBrassinolide neGibberellin kunobatsira kudzikamisa maseru membranes, kukwidziridza kuita kweantioxidant enzymes, uye kunonoka kushatiswa kwema chloroplasts, nekudaro zvichiwedzera kushivirira kwezvirimwa kune zvese kupisa nekusanaya kwemvura.
Chinokurudzirwa Strategy:Kupfapfaidza 0.01–0.1 mg/L Brassinolide kusati kwatanga kupisa kunogona kuvandudza zvakanyanya kushivirira kwezvirimwa zvakaita semagaka. Kune zvirimwa zvakakanganisika nekusanaya kwemvura, musanganiswa wakaderera weGibberellin neBrassinolide unogona kuiswa kuburikidza nemadiridziro ekudonha kubatsira mukudzoreredza kwemabasa emuviri uye kudzivirira kufa kwezvirimwa kwakapararira.
3. Kukurudzira Kushandurwa Kwekudya uye Kukura Kwekubereka
Zhizha rinoratidza nguva yakakosha yekuzadza zviyo uye kugadzika kwemichero muzvirimwa zvakawanda. Nekushandisa nzira ye "Triple Protection Spray" - kushandiswa kwakasanganiswa kwemishonga yezvipembenene, fungicides, uye zvigadziriso zvekukura kwezvirimwa - varimi vanogona kusimudzira zvinobudirira kuzadza zviyo muzvirimwa zvakaita segorosi, nekudaro vachiwedzera kunaka kwezviyo. Common Combinations:
Brassinolide + Monopotassium Phosphate: Inowedzera photosynthetic kunyatsoshanda uye inosimudzira kuendeswa kwezvinovaka muchero.
Gibberellin + Foliar Fertilizer: Inosimudzira kuiswa kwemichero uye kuwedzera, uye inovandudza musika.
