Njengamanje, abalimi abaningi bemifino basebenzisa amanetha anezikhala angu-30 okuvikela izinambuzane, kuyilapho abanye abalimi bemifino basebenzisa amanetha anezikhala angu-60 avikela izinambuzane.Ngesikhathi esifanayo, imibala yamanetha ezinambuzane asetshenziswa abalimi bemifino iphinde ibe mnyama, ansundu, amhlophe, ayisiliva, noluhlaza okwesibhakabhaka.Ngakho hlobo luni lwenethi lezinambuzane olufanele?

Okokuqala, khethaamanetha ezinambuzanengokufanelekile 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.

Khetha amanetha ezinambuzane anemibala ehlukene 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.Ingakhethwa ngokuya ngezidingo zangempela zokusetshenziswa.

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-proof kufanele asetshenziswe ukuze kucatshangelwe ukuthungatha nokupholisa;ezindaweni ezinezintwala eziyingozi kanye nezifo ezibangelwa amagciwane, ukuze ushayele Ukuze ugweme izintwala 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 bavule 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.

3. Lezi zici ezilandelayo kufanele futhi zinakwe lapho ufaka futhi usebenzisa amanetha avikela izinambuzane ezindaweni zokugcina izithombo:
1. Imbewu, inhlabathi, ishede lepulasitiki noma ifreyimu ye-greenhouse, izinto zohlaka, njll. zingaqukatha izinambuzane namaqanda.Emva kokuba inetha elivikela izinambuzane selimboziwe nangaphambi kokutshala izitshalo, imbewu, inhlabathi, uhlaka lwamathambo abamba ukushisa, izinto zohlaka, njll. kumele zilashwe ngesibulali zinambuzane.Lesi isixhumanisi esiyinhloko sokuqinisekisa umphumela wokutshalwa kwenetha lokuvikela izinambuzane nokuvimbela inani elikhulu lezifo nezinambuzane ezinambuzane ekamelweni lenetha.umonakalo omkhulu.

Ukusebenzisa i-thiamethoxam (Acta) + chlorantraniliprole + izikhathi ezingu-1000 zesisombululo se-Jiamei Boni ukuze unisele izimpande kunomphumela omuhle ekuvimbeleni ukuqubuka kwezinambuzane ezihlabayo ezihlabayo kanye nezinambuzane ezingaphansi komhlaba.

2. Lapho utshala, izithombo kufanele zilethwe eshedini nemithi, futhi izitshalo eziqinile ezingenalo izinambuzane nezifo kufanele zikhethwe.

3. Qinisa ukuphathwa kwansuku zonke.Lapho kungena futhi kuphuma ku-greenhouse, umnyango weshede kufanele uvalwe ngokuqinile, futhi izitsha ezifanele kufanele zibulawe amagciwane ngaphambi kokusebenza kwezolimo ukuvimbela ukwethulwa kwamagciwane, ukuze kuqinisekiswe ukusebenza kahle kwenetha lokuvikela izinambuzane.

4. Kubalulekile ukuhlola inetha elivikela izinambuzane njalo ukuze ubone izinyembezi.Uma isitholakele, kufanele ilungiswe kusenesikhathi ukuze kuqinisekiswe ukuthi azikho izinambuzane ezihlasela ku-greenhouse.

5. Qinisekisa ikhwalithi yokufakwa.Inetha elivikela izinambuzane kufanele livalwe ngokugcwele futhi limbozwe, futhi indawo ezungezile kufanele ihlanganiswe nenhlabathi futhi iqiniswe ngokuqinile ngentambo yokubeka;iminyango yokungena nokuphuma eshedeni elikhulu, eliphakathi nendawo kanye ne-greenhouse kufanele ifakwe inethi elivikela izinambuzane, futhi unake ukulivala ngokushesha lapho ungena futhi uphuma.Amanetha angavikeleki ezinambuzaneni amboza ukutshalwa kwamashedi amancane, futhi ukuphakama kwe-trellis kufanele kube kuphakeme kakhulu kunokwezitshalo, ukuze kuvinjwe amaqabunga emifino ukuthi anganamatheli emanethini avikela izinambuzane, ukuze kuvinjwe izinambuzane ukuba zidle ngaphandle. amanetha noma ukubeka amaqanda emaqabunga emifino.Akufanele kube nezikhala phakathi kwenethi elivikela izinambuzane elisetshenziselwe ukuvala indawo yokungenisa umoya kanye nesembozo esibonisa ngale, ukuze kungashiyi umzila lapho izinambuzane zingena futhi ziphuma khona.

6. Izinyathelo eziphelele zokusekela.Ngaphezu kwesembozo esivikela izinambuzane, umhlabathi kufanele ulinywe ngokujulile, futhi kufakwe umanyolo owanele oyisisekelo ofana nomquba wasepulazini obole kahle kanye nenani elincane likamanyolo ohlanganisiwe kufanele kufakwe.Izitshalo kufanele zivundiswe ngesikhathi ngesikhathi sokukhula kanye nesikhathi sokukhula ukuze kuthuthukiswe ukumelana kwesitshalo nengcindezi kanye nezifo.Izinyathelo eziphelele ezisekelayo ezifana nembewu ethuthukisiwe, izibulala-zinambuzane eziphilayo, kanye ne-micro-spraying kanye ne-micro-irrigation ingazuza imiphumela engcono.

7. Inetha elivikela izinambuzane lingahlala lifudumele futhi limanzisa.Ngakho-ke, lapho uqhuba ukuphathwa kwensimu, naka izinga lokushisa kanye nomswakama ekamelweni lenetha, futhi ukhiphe umoya futhi ukhiphe umswakama ngesikhathi ngemva kokuchelela ukuze ugweme izifo ezibangelwa ukushisa nomswakama ngokweqile.

8. Ukusebenzisa nokugcina ngendlela efanele.Ngemva kokuba inetha elivikela izinambuzane selisetshenziswe ensimini, kufanele liqoqwe ngesikhathi, ligezwe, lomiswe, futhi ligingqelwe ukuze lelule isikhathi salo sokusebenza nokwandisa izinzuzo zezomnotho.
