izindaba

1. Ingakwazi ukuvimbela ngokuphumelelayo izinambuzane.Ngemva kokumboza i-inetha lezinambuzane, ngokuyisisekelo ingagwema izinhlobonhlobo zezinambuzane ezinjengezibungu zeklabishi, amabhu e-diamondback, nezintwala.Ngemva kokuba imikhiqizo yezolimo imbozwe amanetha angavikeleki ezinambuzaneni, ingagwema ngokuphumelelayo ukulimala kwezinambuzane ezihlukahlukene ezifana nezibungu zeklabishi, amabhu e-diamondback, ama-cabbage armyworms, i-Spodoptera litura, i-flea beetles, i-simian leaf beetles, ama-aphid nokunye.Ngokusho kokuhlolwa, inethi yokulawula izinambuzane isebenza ngama-94-97% ngokumelene nezibungu zeklabishi, inundu ye-diamondback, i-cowpea pod borer kanye ne-Liriomyza sativa, kanye nama-90% ngokumelene nezintwala.
2. Kungavimbela izifo.Ukudluliswa kwegciwane kungaba nemiphumela eyinhlekelele ekutshalweni kwe-greenhouse, ikakhulukazi ama-aphid.Kodwa-ke, ngemva kokufakwa kwenetha lokuvikela izinambuzane endaweni ebamba ukushisa, ukudluliswa kwezinambuzane kuyanqanyulwa, okunciphisa kakhulu izifo ezibangelwa amagciwane, futhi umphumela wokulawula ungaba ngu-80%.
3. Lungisa izinga lokushisa, izinga lokushisa lomhlabathi kanye nomswakama.Ngenkathi eshisayo, i-greenhouse imbozwa inetha elimhlophe elivikela izinambuzane.Ukuhlolwa kukhombisa ukuthi: ngo-July-August oshisayo, enetha elingu-25-mesh elimhlophe elivikela izinambuzane, izinga lokushisa ekuseni nakusihlwa liyafana nenkundla evulekile, futhi izinga lokushisa licishe libe ngu-1 ℃ kunenkundla evulekile. emini libalele.Kusukela ngoMashi kuya ku-April ekuqaleni kwentwasahlobo, izinga lokushisa eshedini elimbozwe inetha lokuvikela izinambuzane liphakeme ngo-1-2°C kunalelo elisendaweni evulekile, kanti izinga lokushisa endaweni engu-5 cm liphakeme ngo-0.5-1°C. ukuthi endaweni evulekile, engavimbela ngempumelelo isithwathwa.Ngaphezu kwalokho, inetha elivikela izinambuzane lingavimba ingxenye yamanzi emvula ukuba lingangeni eshede, linciphise umswakama ensimini, linciphise izinga lezifo, futhi linciphise ukuhwamuka kwamanzi endlini ebamba ukushisa ngezinsuku libalele.
4. Inomphumela wokufiphaza.Ehlobo, ukukhanya okukhanyayo kukhulu, futhi ukukhanya okunamandla kuzovimbela ukukhula kwemifino yemifino, ikakhulukazi imifino enamahlamvu, futhi inetha elivikela izinambuzane lingadlala indima ethile emthunzini.Inetha le-20-22 mesh silver-gray-proof-proof-proof-proof inetha ngokuvamile inezinga lomthunzi lika-20-25%.
Ukukhetha imodeli
Ekwindla, izinambuzane eziningi ziqala ukuthuthela eshede, ikakhulukazi izinambuzane zebhu kanye ne-butterfly.Ngenxa yobukhulu balezi zinambuzane, abalimi bemifino bangasebenzisa amanetha okulawula izinambuzane anezikhala ezimbalwa, ezifana namanetha angama-30-60 okulawula izinambuzane.Nokho, kulabo abanokhula nezimpukane eziningi ngaphandle kweshede, kubalulekile ukubavimbela ukuba bangangeni ngezimbobo zenetha elivikela izinambuzane ngokobukhulu obuncane bezimpukane.Kunconywa ukuthi abalimi bemifino basebenzise amanetha aqinile angangeni ezinambuzaneni, njenge-40-60 mesh.

Ukukhethwa kombala

Isibonelo, ama-thrips anomkhuba onamandla wokuba luhlaza okwesibhakabhaka.Ukusebenzisa amanetha aluhlaza okwesibhakabhaka okuvikela izinambuzane kungaheha kalula ama-thrip ngaphandle kweshede endaweni ezungezile.Uma inetha elivikela izinambuzane lingavalwanga ngokuqinile, inani elikhulu lama-thrips lizongena eshede futhi libangele ukulimala;Ngokusetshenziswa kwamanetha amhlophe avikela izinambuzane, lesi simo ngeke senzeke ku-greenhouse.Uma isetshenziswe ngokuhambisana namanetha e-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.

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.
Izinyathelo zokuzivikela
1. Ngaphambi kokuhlwanyela noma ukutshala, sebenzisa ishede eliqinile elinokushisa okuphezulu noma fafaza izibulala-zinambuzane ezinobuthi obuphansi ukuze ubulale ama-parasite pupae nezibungu emhlabathini.
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 ebonisa ngale, ukuze kungashiyi ishaneli yokungena nokuphuma ezinambuzaneni.
6. Izinyathelo eziphelele zokusekela.Ngaphezu kokufakwa kwenethi elivikela izinambuzane, kuhlanganiswe nezinyathelo eziphelele ezisekelayo ezifana nezinhlobonhlobo ezimelana nezinambuzane, izinhlobo ezimelana nokushisa, umanyolo wamaphakheji angangcolisi, izibulala-zinambuzane zemvelo, imithombo yamanzi engangcolisi, kanye nokuchela kanye nokuchelela okuncane, imiphumela engcono ingafinyelelwa.
7. 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.
Ukulawula ngokomzimba nokulawulwa kwebhayoloji kunezinzuzo zokungangcolisi indawo ezungezile, kuphephe ezitshalweni, kubantu nasezilwaneni, nasekudleni.Njengohlobo lokulawula ngokomzimba, amanetha okulawula izinambuzane ayizidingo zentuthuko yezolimo yesikhathi esizayo.Ngethemba ukuthi abalimi abaningi bangakwazi ukusebenzisa le ndlela., ukuze kuzuzwe izinzuzo ezingcono zezomnotho nezemvelo.
