IziLawuli eziCetyisiweyo zokuKhula kweZityalo zokuLinywa kwembewu yeRapeseed

Izilawuli zokukhula kwezityalo ezicetyiswayo zokusetyenziswa ngexesha lokukhula kwe-rapeseed (canola) ngokuyinhloko ziquka i-Paclobutrazol (i-Paclo), i-Uniconazole, i-Brassinolide, kunye ne-DCPTA. Imisebenzi yabo ephambili kukulawula ukukhula okugqithisileyo kwezityalo, ukuthintela indawo yokuhlala, ukukhuthaza i-branching, ukomeleza ukumelana noxinzelelo, kwaye ukonyusa kakhulu isivuno.

Ngokukhetha ngokwesayensi abalawuli ngokusekelwe kwiimfuno zomzimba we-rapeseed kwizigaba ezahlukeneyo zokukhula, abalimi banokufikelela kwiinjongo eziphezulu zokuvelisa "izithole ezomeleleyo, iziqu ezinamandla, iintyatyambo ezininzi kunye neepods ezipheleleyo." Oku kulandelayo kuchaza isicwangciso seengcebiso zenqanaba elithile:

I. Inqanaba lezithole (3–6 Inqanaba lamagqabi): Ukukhulisa izithole ezomeleleyo; Ukulawula Ukukhula Okugqithisileyo kunye nokukhuthaza uphuhliso lweengcambu

Olona gxininiso luphambili kweli nqanaba kukuthintela izithole "ezinemilenze" (ubude obugqithisileyo besikhondo) kunye nokomeleza ukuxhathisa ingqele nembalela, ngokwenza njalo kubekwe isiseko esiluqilima sokukhusela ubusika ngokukhuselekileyo.

Paclobutrazol (Paclo)
Ithintela ubude obugqithisileyo bezikhondo kunye namagqabi, ngelixa ikhuthaza ukujiya kwesiseko sesiqu kunye nophuhliso lwenkqubo yeengcambu eyomeleleyo.
**Ixesha lokufaka isicelo:** Ngexesha le-3-5 lenqanaba lamagqabi, okanye iintsuku ezisi-7 phambi kokutshintshwa.
**Umthamo oCetyisiweyo:** 40–60 grams *mu* nganye ye-15% yePaclobutrazol Wettable Powder, exutywe kwiikhilogram ezingama-30–40 zamanzi okutshiza ngamagqabi.
**Ukomelezwa kweSivuno:** Kunokunyusa isivuno nge-8% -12%, ngelixa kuqinisa ngokubonakalayo ukuxhathisa indawo yokuhlala.

Uniconazole
Unomsebenzi ophezulu webhayoloji kwaye ufuna amazinga asezantsi ezicelo; ilungele ukulima imbewu yedlwengulo okanye amasimi apho ukunciphisa iintsalela zemichiza kuyinto ephambili.
**Umthamo ocetyiswayo:** 30–45 grams *mu* ye-5% yokwenziwa kwe-Uniconazole, exutywe emanzini ukutshiza okufanayo kwamagqabi.

Brassinolide / Diethyl aminoethyl Hexanoate (DA-6)
Ilungele amasimi anezithole ezibuthathaka; ikhuthaza ukukhula kwaye ikhawulezise inguqu ukuya kwinqanaba eliqinileyo lezithole.
**Iingcebiso ezidityanisiweyo:** Xuba-tshiza ngeMonopotassium Phosphate ukomeleza ukuxhathisa koxinzelelo.


II. I-Budding kunye ne-Bolting Stage (Ubude be-Stem: 5-15 cm): Lawula ukuKhula okuBumandla kunye nokuthintela ukuHlaliswa; Khuthaza iSebe
Eli nqanaba liphawula inguqu ebalulekileyo ukusuka ekukhuleni kwezityalo ukuya ekukhuleni kwenzala. Ukulawula ukukhula okugqithisileyo kwezityalo kuthintela ukugquma kwangaphambi kwexesha kunye neentyatyambo, ngelixa kukhuthaza ukuhlukana kwesebe.

Paclobutrazol (Paclo)
**Elona xesha lifanelekileyo:** Inqanaba lokuqala lebholithi (ubude besiqu: 5–10 cm).
**Umsebenzi:** Inqanda i-etiolation (ukukhula komlenze) kwesiqu esingundoqo, yonyusa inani lamasebe asebenzayo nge-2–3, kwaye yonyusa ukuxinana kwemidumba ngama-20%.
**Ifomula ecetyiswayo:** 50–60 g ye-15% yePaclobutrazol + 100 g ye-99% ye-Monopotassium Phosphate nge-15-20 catties (30-40 *jin*) yamanzi. Faka isicelo ngesitshizi samagqabi amaxesha ama-2-3, kunye nekhefu leentsuku eziyi-10-15 phakathi kokufakwa.

Brassinolide
Ingasetyenziselwa i-synergistically kunye ne-Paclobutrazol ukunciphisa inhibition yokukhula okubangelwa unyango lokulawula ukukhula kunye nokuphucula ukusebenza kakuhle kwe-photosynthetic.

III. Iintyatyambo ukuya kwi-Pod-Setting Stage (Iintyatyambo zaKwangoko-Iintyatyambo eziNcopho): Gcina iintyatyambo kunye neePods; Thintela Ukuvela Kwangaphambi kwexesha
Injongo ngeli nqanaba kukuphucula umgangatho womvumvuzelwano, ukuthintela "iintyatyambo ezingaboniyo" (iintyatyambo ezisilelayo ukubeka imidumba), kunye nokuthintela ukuvuthwa kwangaphambi kwexesha okubangelwa ngamaqondo obushushu aphezulu.

Brassinolide + Monopotassium Phosphate + Boron Fertilizer
Ukuphumeza isicwangciso-qhinga "soNkuthazo olunye, uThintelo olune": Ukukhuthaza ukukhula; ukukhusela izinambuzane kunye nezifo; ukunqanda ukuqaqanjelwa kwangaphambi kwexesha; thintela iintyatyambo eziyimfama; kunye nokuthintela ukuvuthwa kwangaphambi kwexesha okubangelwa ngamaqondo obushushu aphezulu.
**Ixesha eliCetyisiweyo:** Faka kube kanye ngexesha lokuntshula kweentyatyambo (xa i-20% yeentyatyambo sele ivulile) nakanye ngexesha lencopho yeentyatyambo (xa i-50% yeentyatyambo ivulile).
**Udibaniso lwemichiza yokungunda:** Ingaxutywa nemichiza yokungunda efana neProchloraz okanye iProcymidone ukuthintela ukubola kwesiqu seSclerotinia.

I-DCPTA
Isebenza ukusuka kwinqanaba lesikhondo ukuya kutsho kwinqanaba lokuntshula kweentyatyambo, isebenza ngokuthe ngqo kwinucleus yeseli ukuze iphucule ukusebenza kakuhle kwephotosynthetic, inika umlinganiselo wokunyuka kwemveliso yezityalo nge-15% ukuya kuma-25%.

IV. Ngaphambi kokuQala komonakalo weFrost okanye uxinzelelo lweNdawo: Ukuphucula ukuchasana noxinzelelo
Kwiintsuku eziyi-10-15 ngaphambi kokufika kwamaqondo obushushu aphantsi, faka isitshizi se-foliar se-Brassinolide, isichumiso se-amino acid esinyibilikayo emanzini ukuxhasa ukuxhathisa kweqabaka.
Kwimeko yokonakala kweFrost: Faka ngokukhawuleza isitshizi sokubulala umngundo ukuze uvale amanxeba, kwaye usebenzise ngokudibeneyo nokulawula ukukhula kwezityalo ukwenza lula ukuchacha.
