Ndezvipi zvinogadzirisa kukura kwezvirimwa zvinoita kuti miti ikure nekukurumidza?

Iwo anonyanya kushanda ekukura mirau yekukurumidza kukura kwemuti anosanganisira GA3, cytokinins, uye sodium nitrophenolates.

Kukura kwemiti kunopesvedzerwa nemajini ayo, mamiriro ezvakatipoteredza, uye vanodzora kukura. Pasi pemamiriro ekugadzirisa uye chiedza chinodzorwa, kushandiswa kwesayenzi kwezvinomera zvinokura zvinogadzirisa zvinogona kukurumidza kukurumidza kukura kwemiti, asi rudzi rwakakodzera runofanira kusarudzwa zvichienderana nemhando chaiyo yemiti yemiti.

1. Gibberellic Acid (GA3)

Gibberellic Acid ndeimwe yeanonyanya kushandiswa kukura regulators. Iyo inowedzera zvakananga kuwedzera kwekuwedzera kwehunde nematavi nekukurudzira sero elongation. Kupfapfaidza mashizha ane 50-100 ppm gibberellic acid solution pamiti yemichero yakaita secitrus nemazambiringa kunogona kuwedzera kukura kwepfuti ne20% -35% (2023 data yekuedza).

2. Cytokinins (se6-BA)
Aya maregulator anowedzera kupatsanurwa kwesero, uye anonyanya kukodzera kune lateral bud kumera uye kuwedzera bazi uye mashizha density. Kupfapfaidza madzinde emupoplar ne 0.1% concentration ye6-BA kunogona kuwedzera huwandu hwemapazi eparutivi nekanopfuura katatu mushure memazuva gumi nemashanu. Nekudaro, kushandisa zvakanyanya kunogona kutungamirira kumashizha akawandisa, zvichikanganisa kupinda kwechiedza.

3. Sodium Nitrophenolates: Sodium nitrophenolates ine zvose zvinokurudzira kukura uye kusagadzikana-kusagadzikana kwemabasa, kukurumidza kuunganidzwa kwezvokudya kuburikidza nekusimudzira photosynthetic kunyatsoshanda. Kupfapfaidza madzinde epapine ne 1.8% aqueous solution yakadirwa ka6000, yakasanganiswa nenitrogen fertilizer, inogona kuwedzera kukura kwegore negore ne40%.

Mushure mekunzwisisa misimboti, pfungwa mbiri dzinofanira kucherechedzwa: Kutanga, mutongi anofanira kushandiswa panguva imwe chete nehwaro fetiraiza. Semuenzaniso, kushandisa phosphorus uye potassium fetiraiza usati uye mushure mekushandisa gibberellin kunogona kudzivirira zvakanyanya kukura kwezvinomera. Chechipiri, iyo yakakwana nguva yekushandisa ndeyekubva pabud break kusvika pakukura nekukurumidza; kumwaya panguva yedormancy kunogona kutadzisa kukura.

Munharaunda dzekuchamhembe, kana uchidyara miti inodonha, zvinokurudzirwa kupfapfaidza katatu panguva kubva pakupera kwaApril kusvika pakati paJune, nepo kune miti yakasvibira kumaodzanyemba, inogona kuwedzerwa kusvika munaGunyana.

A practical reference reshiyo ndeiyi: 10 magiramu egibberellin + 30 magiramu e potassium dihydrogen phosphate yakadirwa mu 15 kg yemvura, ichitarisa pakupfapfaidza nhungirwa nyoro uye pasi pemashizha. Kana zvisizvo zvakaita sekupeta kwemashizha zvikaonekwa, sukurudza nekukurumidza nemvura yakachena woisa fetireza yecalcium nemagnesium kuti dambudziko ripere.

Ongororo dzinoratidza kuti kushandiswa kwakasanganiswa kwevatongi uye microbial agents kunoshanda zvakanyanya. Semuyenzaniso, kushandisa Bacillus subtilis semvura inonyorovesa midzi mazuva matatu mushure mekupfapfaidza Sodium Nitrophenolates kunogona kuvandudza mwero wekutorwa kwechikafu chemidzi, zvichikonzera kukora gore negore kwemiti yemhashu iri kukura zvinopeta ka1,5 pane yenguva dzose.
