Njengamanje, abalimi abaningi bemifino basebenzisa i-30-meshamanethi angangeni ezinambuzaneni,kuyilapho abanye abalimi bemifino besebenzisa amanetha angangeni ezinambuzaneni angama-60.Ngesikhathi esifanayo, imibala yamanetha ezinambuzane asetshenziswa abalimi bemifino iphinde ibe mnyama, ansundu, amhlophe, ayisiliva, noluhlaza okwesibhakabhaka.Ngakho hlobo luni lwenethi lezinambuzane olufanele?
Okokuqala, khetha amanetha ezinambuzane ngokunengqondo ngokwezilokazane okufanele zigwenywe.Ngokwesibonelo, kwezinye izinambuzane zebhu kanye novemvane, ngenxa yobukhulu balezi zinambuzane, abalimi bemifino bangasebenzisa amanetha okulawula izinambuzane anezikhala ezimbalwa, njengamanetha angu-30-60 okulawula izinambuzane.Kodwa-ke, uma kukhona ukhula nezimpukane eziningi ngaphandle kweshede, kuyadingeka ukuthi zingangeni ngezimbobo zenetha elivikela izinambuzane ngokobukhulu obuncane bezimpukane.Kunconywa ukuthi abalimi bemifino basebenzise amanetha aqinile angangeni ezinambuzaneni, njenge-50-60 mesh.
Okwesibili, khetha imibala ehlukene yamanethi ezinambuzane ngokwezidingo ezahlukene.Ngenxa yokuthi ama-thrips anomkhuba onamandla wokuba luhlaza okwesibhakabhaka, ukusetshenziswa kwamanethi aluhlaza okwesibhakabhaka avikela izinambuzane kulula ukuheha ama-thrip ngaphandle kweshede endaweni ezungezile ye-greenhouse.Uma inetha elivikela izinambuzane lingavalwanga ngokuqinile, inani elikhulu lama-thrips lizongena eshede futhi libangele ukulimala;Ukusebenzisa inetha elimhlophe lokufaka izinambuzane, lesi senzakalo ngeke senzeke ku-greenhouse, futhi uma sisetshenziswa ngokuhambisana nenetha le-shading, kufanelekile ukukhetha okumhlophe.Kukhona nenethi elivikela izinambuzane elisiliva elimpunga elinomphumela omuhle wokuxosha ama-aphid, futhi inetha elimnyama elivikela izinambuzane linomphumela obalulekile wokufiphaza, ongafanele ukusetshenziswa ebusika ngisho nezinsuku eziguqubele.Ungakhetha ngokuvumelana nezidingo zangempela.
Ngokuvamile uma kuqhathaniswa nehlobo entwasahlobo nasekwindla, lapho izinga lokushisa liphansi nokukhanya kubuthakathaka, kufanele kusetshenziswe amanetha avikela izinambuzane;ehlobo, amanetha amnyama noma isiliva-grey-proof-proof kufanele asetshenziswe ukuze kucatshangelwe ukuthungatha nokupholisa;ezindaweni ezinezintwala eziyingozi kanye nezifo zegciwane, ukuze ushayele Ukuze ugweme ama-aphid futhi uvimbele izifo ezibangelwa amagciwane, kufanele kusetshenziswe amanetha avikela izinambuzane.
Futhi, lapho ukhetha inetha elivikela izinambuzane, kufanele futhi unake ukuze uhlole ukuthi inethi yokuvikela izinambuzane iphelele yini.Abanye abalimi bemifino babike ukuthi amanetha amaningi avikela izinambuzane abasanda kuwathenga ayenezimbobo.Ngakho-ke, bakhumbuza abalimi bemifino ukuthi kufanele bembule amanetha angavimbeli izinambuzane lapho bethenga ukuze bahlole ukuthi amanetha avikela izinambuzane anazo yini izimbobo.
Kodwa-ke, siphakamisa ukuthi uma usetshenziswa wedwa, kufanele ukhethe okunsundu noma okwesiliva-grey, futhi uma kusetshenziswe ngokuhambisana namanetha omthunzi, khetha isiliva-grey noma emhlophe, futhi ngokuvamile ukhethe i-50-60 mesh.
