Inetha elivikela izinambuzane lifana nesikrini sefasitela, elinamandla aqinile, ukumelana ne-UV, ukumelana nokushisa, ukumelana namanzi, ukumelana nokugqwala, ukumelana nokuguga nezinye izakhiwo, ezingenabuthi futhi ezingenakunambitheka, futhi impilo yayo yesevisi ngokuvamile iyiminyaka engu-4-6. , kuze kufike eminyakeni eyi-10.Akukona nje kuphela ukuthi kunezinzuzo ze-sunshade, kodwa futhi kunqoba ukungalungi kwe-sunshade, futhi kufanelekile ukukhuthazwa ngamandla.
Izinkinga eziningana ezidinga ukunakwa ekukhetheniinetha lezinambuzane
Njengamanje, abalimi abaningi bemifino basebenzisa i-30-meshamanetha ezinambuzane, kuyilapho abanye abalimi bemifino basebenzisa i-60-meshamanetha ezinambuzane.Ngesikhathi esifanayo, abalimi bemifino nabo basebenzisa umnyama, onsundu, omhlophe, osiliva noluhlaza okwesibhakabhakaamanetha ezinambuzane, ngakho hlobo luni lwenethi lezinambuzane olufanele?
Okokuqala nje, amanetha okuvikela izinambuzane kufanele akhethwe ngokunengqondo ngokwezilokazane okufanele zigwenywe.Ngokwesibonelo, izinambuzane eziningi zaqala ukuthuthela eshede ekwindla, ikakhulukazi ezinye izinambuzane inundu kanye butterfly.Ngenxa yobukhulu balezi zinambuzane, abalimi bemifino bangasebenzisa amanetha amancane okuvimbela izinambuzane, njengamanethi okuvimbela izinambuzane angama-30-60.Kodwa-ke, kulabo abanokhula olwengeziwe kanye ne-whitefly ngaphandle kweshede, kuyadingeka ukuvimbela i-whitefly ukuthi ingangeni ngembobo yenetha lokuvimbela izinambuzane ngokobukhulu bayo obuncane.Kunconywa ukuthi abalimi bemifino basebenzise inetha eliminyene lokuvimbela izinambuzane, njenge-40-60 mesh.
Okwesibili, khetha imibala ehlukene yamanethi ezinambuzane ngokwezidingo ezahlukene.Ngenxa yokuthi ama-thrips anomkhuba onamandla wokuba luhlaza okwesibhakabhaka, kulula ukukhanga ama-thrip ngaphandle kweshede endaweni ezungezile ye-greenhouse ngokusebenzisa okuluhlaza okwesibhakabhaka.inetha elilwa nezinambuzane.Uma inetha elilwa nezinambuzane lingamboziwe ngokuqinile, inani elikhulu lama-thrips lizongena eshede futhi libangele ukulimala;Uma usebenzisa inetha lezinambuzane ezimhlophe, lesi simo ngeke senzeke ku-greenhouse, futhi uma usebenzisa net sunshade, kungcono ukhethe okumhlophe.Olunye uhlobo lwenethi lokuvikela izinambuzane ezisiliva-grey lunomphumela omuhle wokuxosha kuma-aphid.Inetha elimnyama lokuvimbela izinambuzane linomphumela obalulekile we-shading, futhi alifanele ukusetshenziswa ebusika ngisho nezinsuku eziguqubele.Ungakhetha ngokuya ngezidingo zangempela zokusetshenziswa.
Ngokuvamile, entwasahlobo nasekwindla, uma kuqhathaniswa nehlobo, izinga lokushisa liphansi futhi ukukhanya kuba buthakathaka, kumhlophe kakhuluinetha lezinambuzanekufanele kukhethwe;Ehlobo, ukuze ucabangele ukuthungatha nokupholisa, amanetha okuvimbela izinambuzane amnyama noma isiliva-grey kufanele akhethwe;Ezindaweni lapho izifo ze-aphid ne-virus ziyingozi kakhulu, kufanele kukhethwe amanetha okuvimbela izinambuzane ukuze kuxoshwe ama-aphid futhi kuvimbele izifo zegciwane.
Okwesithathu, lapho ukhetha ifayelainethi elilwa nezinambuzane,qaphela ukuhlola ukuthi inetha lokulwa nezinambuzane liphelele yini.Abanye abalimi bemifino babike ukuthi amanetha amaningi okuvikela izinambuzane asanda kuthengwa anemigodi, ngakho bakhumbuza abalimi bemifino ukuba bandise amanetha okuvimbela izinambuzane futhi bahlole ukuthi ayikho yini imigodi emanethini okuvimbela izinambuzane lapho bethenga.
Kodwa-ke, siphakamisa ukuthi uma isetshenziswe yedwa, ikhofi nesiliva grey kufanele kukhethwe, kuyilapho uma isetshenziswa ngesikrini se-shading, isiliva grey nomhlophe kufanele kukhethwe.Ngokuvamile, i-40-60 mesh kufanele ikhethwe.
