Obhekilanga badabuka eNingizimu Melika, bafuywa amaSpanish ngo-1510 ukusuka eNyakatho Melika kuya eYurophu, ekuqaleni ukuze basetshenziswe ukuhlobisa.Ikhulu le-19, futhi yethulwa emuva eNyakatho Melika isuka eRussia.Zilinywa eChina.Imbewu kabhekilanga ibizwa ngokuthi imbewu kabhekilanga futhi ivame ukuthoswa futhi idliwe njengokudla okulula, okumnandi.

What Do You Know about the Key Points of Growing Sunflowers?

1. Hlobo luni lwenhlabathi ubhekilanga abathanda ukukhula kulo?

Ezindaweni eziningi ubhekilanga utshalwa endaweni enosawoti, enesihlabathi kanye nomhlabathi owomile, ikakhulukazi ngenxa yokuthi awuzweli futhi ubiza kakhulu kunezinye izitshalo.Nakuba ubhekilanga ungenazo izidingo zomhlabathi eziqinile, ungakhula kuzo zonke izinhlobo zenhlabathi, kusukela emhlabathini ovundile kuya emhlabathini owomile, ongavundile kanye nosawoti.Kodwa-ke, amandla okwandisa isivuno makhulu uma kutshalwe emasimini anengqimba ejulile, okuqukethwe kwe-humus ephezulu, ukwakheka okuhle kanye nokugcinwa kwamanzi okuhle nomanyolo.Isivuno esingcono kanye nezinzuzo eziphezulu zezomnotho zingatholakala.

2. Iyini i-dormancy yembewu ye-sunflower?

Endabeni yembewu kabhekilanga kawoyela, i-dormancy ngokuvamile iba yizinsuku ezingama-20 kuya kwezingama-50 ngemuva kokuvuna.I-Dormancy ibalulekile ngokwebhayoloji njengoba ivumela imbewu ukuthi ihlale 'ilele' kuze kufike isikhathi sokuhlwanyela esivamile.Ukuhluma kungagwenywa kudiski ngesikhathi sokuvuna ukuvuthwa kwembewu, noma kwenzeka kuba nezimvula eziqhubekayo.Le dormancy izodlula ngokwemvelo ngemva kwesivuno salo nyaka kanye nenkathi yokuhlwanyela elandelayo.Ezimweni ezingavamile lapho imbewu esanda kuvunwa isetshenziselwa ukuhlwanyela noma umsebenzi wokucwaninga, ukulala kungaphulwa ngesandla.Ngokuvamile, imbewu icwiliswe kwisisombululo se-50 kuya ku-100 micrograms / ml ye-ethylene glycol amahora angu-2 kuya kwangu-4 bese imila ngaphansi kwezimo ezifanele.I-Gibberellin iyasiza futhi ekwephuleni i-dormancy kumbewu ye-sunflower enembewu yamafutha.

3. Yiziphi izimo zezulu ezifanele ukulinywa kukabhekilanga?
