Ukusetshenziswa kwezilawuli zokukhula kwezitshalo ku-Cosmos
I-Cosmos inemibala ecebile futhi enemibala, ehlanganisa emhlophe, epinki, ebomvana, ebomvu, ebomvu emnyama, ebomvu ebomvu, ebomvu ebomvu, eluhlaza okwesibhakabhaka nezinye izinhlobo. Ngaphezu kwalokho, inesikhathi eside sokuqhakaza futhi kulula ukuyitshala. Ivame ukusetshenziswa njengesizinda semibhede yezimbali, imingcele yezimbali, amaqembu ezimbali, noma itshalwe ngeziqephu emaphethelweni otshani, ezizungeze izihlahla kanye nasemgwaqweni. Ingasetshenziswa futhi njengembali enqunyiwe.
Ukusetshenziswa okuyinhloko kwezilawuli zokukhula kwezitshalo ku-cosmos:
1. Vimbela izithombo ukuthi zingakhuli zibe zinde futhi zihlale
I-Paclobutrazol:
Sebenzisa isixazululo esingu-667mg/LPaclobutrazol ukucwilisa imbewu ye-cosmos amahora ama-2 ngaphambi kokuhlwanyela. Ukufana kwezithombo kuphezulu futhi umphumela omncane uyabonakala.
I-Chlormequat Chloride, i-Daminozide:
Fafaza 400mg/L Chlormequat Chloride noma 3000mg/L isixazululo se-Daminozide izikhathi ezintathu esigabeni samaqabunga amabili, amaqabunga amane, kanye namaqabunga ayisithupha e-Cosmos, engalawula ngempumelelo ubude besitshalo, ukujiya kwesiqu, kanye nama-internode esitshalo. I-cosmos, ivimbela ukukhula ngokweqile kwezithombo kumathreyi amapulaki, yenza isitshalo sihlangane, futhi ibambe iqhaza elikhulu ekutshaleni izithombo eziqinile.
2. Lawula ukuphakama kwezitshalo zasebhodweni
I-Daminozide:
Ngemva kokumpintsha phezulu kwe-Cosmos ebhodweni, fafaza amaqabunga ngesixazululo se-5000mg/L se-Daminozide, kanye njalo ezinsukwini eziyi-10 kuya kweziyi-14, futhi uqhubeke ufutha kuze kuvele imiqumbe, okunganciphisa kakhulu ubude besitshalo futhi kuthuthukise ukubaluleka kokuhlobisa.
I-Paclobutrazol/Uniconazole:
Lapho ukuphakama kwesitshalo se-cosmos esisetshenziswa olwandle lwembali kungu-10 ~ 15cm, fafaza amaqabunga nge-125 ~ 150mg/LPaclobutrazol noma i-50mg/LUniconazole isixazululo izikhathi ezingu-1 ~ 2, okungenza isitshalo sibe mfushane futhi siqine, andise. ukujiya kwesiqu, kujulise umbala wamaqabunga, futhi kwandise ukumelana nendawo yokulala.
3. Thuthukisa ukuhluma kwama-lateral bud kanye nokuhlukaniswa kwezimbali
I-6-Benzylaminopurine (6-BA):
Uma ukuphakama kwesitshalo se-cosmos kungu-5~10cm, sifafaze ngesisombululo se-20~25mg/L 6-BA ukukhuthaza ukuhluma kwama-lateral buds. Sebenzisa isixazululo esingu-20~25mg/L 6-BA ufafaze izikhathi ezingu-1 ~ 2 esigabeni sokuqala sezimbali ze-cosmos, ezingandisa inani lezimbali futhi zikhulise izimbali zezimbali.
4. Thuthukisa ikhono lezitshalo ezisendaweni evulekile ukumelana nezinga lokushisa eliphezulu kanye nesomiso
I-S-abscisic Acid (S-ABA):
I-cosmos esetshenziswa ezitshalweni ezivulekile (okuhlanganisa izingadi zasemadolobheni, amasimu ezimbali, nezindawo ezibukeka kahle) ithola kalula ukushiswa yilanga okunamandla kanye nengcindezi yesomiso ngemva kokuhwamuka okukhulu esimweni sezulu esishisayo sasehlobo. Ukufafaza u-2-5mg/L wesisombululo se-S-abscisic Acid (S-ABA) emaqabunga kungakhuphula ikhono le-Cosmos lokumelana nezinga lokushisa eliphezulu kanye nesomiso.
