Uhla lwezinambuzane ezibulala izinambuzaneI-Dinotefuranibanzi kakhulu, futhi ayinawo ukumelana nezinto ezisetshenziswa kakhulu, futhi inomphumela omuhle wokumunca nokudlulisa ngaphakathi, futhi izingxenye ezisebenzayo zingathuthwa kahle kuzo zonke izingxenye zezicubu zezitshalo. Ikakhulukazi, ukulawulwa kwama-aphid, izimbungulu, izitshalo zelayisi, ama-thrip nezinye izinambuzane ezihlabayo bekuphumelele kakhulu. Ngaphezu kwalokho, kungaphinde kufinyelele umphumela onembile wokuvimbela ukumunca kwezinambuzane.
1. Izitshalo zemifino (kusetshenziswa ama-granule angu-l% kanye nama-granule angu-20% ancibilika emanzini): ama-granule angu-l% angaxutshwa nomhlabathi onemigodi yenhlabathi ngesikhathi sokufakelwa kwezithelo nemifino kanye nemifino enamaqabunga, noma axutshwe nomhlabathi osemathinini okutshala ngesandla ngesikhathi sokutshala. Lokhu kungalawula izinambuzane ezidla ezinye ngesikhathi sokufakelwa kanye nezinambuzane ezindizayo ngaphambi kokufakelwa. Ngaphezu kwalokho, ngoba umuthi unomthelela omuhle wokumunca nokudlulisa, ungamuncwa ngokushesha yizitshalo ngemva kokwelashwa, futhi ungagcina ukusebenza kahle amasonto angu-4 kuya kwangu-6.
Ama-granule ancibilika emanzini angu-20% angasetshenziswa njengezinto zokwelapha izimpande namaqabunga ukulawula izinambuzane. Izindlela ezimbili zokwelapha, “ukwelashwa kokufakelwa kwamanzi” kanye “nokwelashwa kokufakelwa komhlabathi ngesikhathi sokukhula”, ziyahlolwa. Ama-granule ashiwo ngenhla angahlanganiswa nama-granule ancibilika emanzini ukuze asetshenziswe kusukela ekuqaleni kokukhula kwesitshalo kuze kube sekuvunweni.
2. Izihlahla zezithelo (20% ama-granule ancibilika emanzini): Ama-granule ancibilika emanzini asetshenziswa njengezinto zokwelapha isiqu namaqabunga lapho kuvela izinambuzane, ezingalawula ngempumelelo ama-aphid, izinambuzane ezimunca izinambuzane ze-red scale, izinambuzane zokudla, kanye nezinambuzane ze-lepidoptera. Ngaphezu kwalokho, futhi inomphumela omuhle wokubulala izinambuzane ezizinambuzaneni, kanye nokuvimbela okuphezulu kokumunca. Akukho monakalo ezitshalweni lapho kusetshenziswa umthamo, futhi izitshalo nazo ziba ziningi lapho umthamo uphindwe kabili. Njengoba usetshenziswa ezitshalweni zemifino, unomphumela wokungena nokufuduka kusuka ebusweni beqabunga kuya eqabungeni ngaphakathi. Ngesikhathi esifanayo, kunezitha zemvelo ezibaluleke kakhulu ezihlahleni zezithelo.
3, Ilayisi (2% ama-granule ebhokisi lezithombo, ama-granule angu-l%, i-0.5% DL powder): Uma isetshenziswa elayisini, i-DL powder kanye nama-granule angasetshenziswa kumthamo ongu-30kg/hm2 (isithako esisebenzayo esingu-10 ~ 20g/hm2), esingalawula ngempumelelo izikelemu zezitshalo, i-black-tailed leafhopper, izinambuzane zodaka olune-rice negative kanye nezinye izinambuzane. Ikakhulukazi ezilokazane, umehluko wokusebenza kahle kwemithi phakathi kwezinhlobo zinhlobo mncane kakhulu. Ngemva kokusebenzisa ibhokisi lezithombo, lingalawula ngempumelelo i-planthopper, i-black-tailed leafhopper, i-rice bug kanye ne-rice tube water borer ngemva kokufakelwa. Umuthi unomthelela omude osele ezinambuzaneni ezihlosiwe, futhi usengalawula ngempumelelo ubuningi bezinambuzane ngemva kwezinsuku ezingu-45. Njengamanje, kwenziwa izivivinyo ezengeziwe ezinambuzaneni ezifana ne-Borer, i-rice borer kanye ne-rice black bug.
