Ubhekilanga wuhlobo lukabhekilanga emndenini wakwa-Asteraceae, okuyigama elithi: imbali yokuphuma kwelanga, ubhekilanga, ubhekilanga, ubhekilanga, ubhekilanga.Abantu abaningi baye badla imbewu ye-sunflower , etshalwa yi-sunflower, kungakanani okwaziyo ngamaphuzu abalulekile okukhula kukabhekilanga?Okulandelayo umthengisi wembewu kabhekilanga uzokwethula amaphuzu abalulekile okukhulisa ubhekilanga.
Obhekilanga badabuka eNingizimu Melika, bafuywa amaSpanish ngo-1510 ukusuka eNyakatho Melika ukuya 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.
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 nosawoti.Nokho, amandla okwandisa isivuno makhulu uma kutshalwe emasimini anengqimba ejulile, okuqukethwe kwe-humus ephezulu, isakhiwo esihle 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 ivamise ukuba yizinsuku ezingama-20 kuya kwezingama-50 ngemuva kokuvuna.I-Dormancy ibalulekile ngokwezinto eziphilayo 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 icwiliswa kwisisombululo se-50 kuya ku-100 micrograms / ml ye-ethylene glycol amahora angu-2 kuya kwangu-4 bese ihluma ngaphansi kwezimo ezifanele.I-Gibberellin iyasiza futhi ekwephuleni i-dormancy kumbewu ye-sunflower enembewu yamafutha.
3. Yiziphi izimo zezulu ezifanele ukulinywa kukabhekilanga?
Ubhekilanga uyisitshalo esithanda izinga lokushisa futhi uyisitshalo esibekezelela amakhaza esikwazi ukuzivumelanisa nezimo zezulu.Uma izinga lokushisa lomhlabathi ongqimbeni lomhlabathi (0-20 cm) lifinyelela ku-2°C, imbewu iqala ukuhluma, i-4-6°C ingaqhuma futhi i-8-10°C ingasetshenziswa ekukhuleni kwezithombo.Ngaphezu kwalokho, ukuvela kwezithombo kuhlobene eduze nekhwalithi yembewu, umswakama, umoya-mpilo kanye nokwakheka kanye nesakhiwo senhlabathi.
Ubhekilanga uwoyela jikelele kusukela esithombweni kuya ekuvuthweni isidingo ≥ 5 ℃ ngempumelelo cumulative lokushisa mayelana 1700 ℃;Ubhekilanga odliwayo kusukela kusithombo kuye ekuvuthweni udinga ≥ 5 ℃ izinga lokushisa elisebenzayo elihlanganisayo elingaba ngu-1900 ℃.
