Yiziphi izilawuli zokukhula kwezitshalo ezisetshenziselwa ubhontshisi oluhlaza?

Lapho utshala ubhontshisi obuluhlaza, izinkinga ezihlukahlukene zokutshala zivame ukuhlangana nazo, njengokuthi indawo yokubeka ubhontshisi oluhlaza iphezulu kakhulu, noma izitshalo zikabhontshisi zikhula ngamandla, noma izitshalo zikhula kancane, noma ubhontshisi obuluhlaza buba nezimbali kanye nezidumba eziwayo, njll. Ngalesi sikhathi, ukusetshenziswa kwesayensi kwezilawuli zokukhula kungathuthukisa kakhulu isimo, ukuze ubhontshisi uqhakaze kakhulu futhi usethe ama-pods amaningi, ngaleyo ndlela andise isivuno sikabhontshisi oluhlaza.

(1) Khuthaza ukukhula kukabhontshisi oluhlaza
I-Triacontanol:
Ukufafaza i-Triacontanol kungakhuphula izinga lokumisa i-pod likabhontshisi oluhlaza. Ngemva kokufafaza i-Triacontanol kubhontshisi, izinga lokumisa i-pod lingakhuphuka. Ikakhulukazi entwasahlobo lapho izinga lokushisa eliphansi lithinta ukumiswa kwe-pod, ngemva kokusebenzisa ukwelashwa kotshwala kwe-Triacontanol, izinga lokusetha i-pod lingakhuphuka, elihambisana nokuvuna okuphezulu kwasekuqaleni kanye nezinzuzo zezomnotho ezikhulayo.

Ukusetshenziswa kanye nomthamo:Ekuqaleni kwesikhathi sokuqhakaza kanye nesigaba sokuqala sokumiswa kwe-pod kabhontshisi oluhlaza, fafaza sonke isitshalo nge-Triacontanol 0.5 mg/L isisombululo sokugxilisa ingqondo, bese ufafaza amalitha angama-50 mumu ngayinye. Naka ukufutha i-Triacontanol kubhontshisi oluhlaza, futhi ulawule ukugxila ukuze uvimbele ukugxilisa ingqondo ekubeni phezulu kakhulu. Ingaxutshwa nezibulala-zinambuzane kanye nezakhi zokulandelela lapho ufafaza, kodwa ayikwazi ukuhlanganiswa nezibulala-zinambuzane ezine-alkaline.

(2) Lawula ubude bezitshalo futhi ulawule ukukhula okunamandla
I-Gibberellic Acid GA3:
Ngemva kokuvela kukabhontshisi oluhlaza, fafaza ngesixazululo se-Gibberellic Acid GA3 esingu-10 ~ 20 mg/kg, kanye njalo ezinsukwini ezi-5, izikhathi ezi-3, okungenza amaqhuqhuva abe made, andise amagatsha, aqhakaze futhi asheshe, futhi thuthukisa isikhathi sokuvuna ngezinsuku ezi-3-5.

I-Chlormequat Chloride (CCC), i-Paclobutrazol (Paclo)
Ukufafaza i-chlormequat ne-paclobutrazol phakathi nesikhathi sokukhula kukabhontshisi oluhlaza onwabuzelayo kungalawula ukuphakama kwesitshalo, kunciphise ukuvala futhi kunciphise ukuvela kwezifo nezinambuzane.
Sebenzisa ukugxila: I-Chlormequat Chloride (CCC) ingu-20 mg/ igremu elomile, i-Paclobutrazol (Paclo) ingu-150 mg//kg.

(3) Khuthaza ukuzalwa kabusha
I-Gibberellic Acid GA3:
Ukuze kuthuthukiswe ukuhluma kwemiqumbe emisha ekupheleni kwesikhathi sokukhula kukabhontshisi oluhlaza, isixazululo se-Gibberellic Acid GA3 esingama-20 mg/kg singafafazwa ezitshalweni, ngokuvamile kanye ezinsukwini ezi-5, futhi izifutho ezi-2 zanele.

(4) Nciphisa ukuchitheka
I-1-Naphthyl Acetic Acid (NAA):
Uma ubhontshisi uqhakaza futhi wenza ama-pods, amazinga okushisa aphezulu noma aphansi azokwandisa ukuchitheka kwezimbali kanye nama-pods kabhontshisi oluhlaza. Ngesikhathi sokuqhakaza kukabhontshisi oluhlaza, ukufafaza 5~15 mg/kg 1-Naphthyl Acetic Acid (NAA) isisombululo kunganciphisa ukuchitheka kwezimbali nama-pods futhi kungabasiza ukuthi bavuthwe ngaphambi kwesikhathi. Njengoba inani lama-pods likhula, umanyolo kufanele wengezwe ukuze uthole isivuno esiphezulu.
