2. Izinyathelo zobuchwepheshe

(1) Ukutshala phakathi kwebhande likabhontshisi wesoya nommbila

Eningizimu-ntshonalanga yeChina, kunemvula eningi, izinhlobo eziningi zokhula, futhi kunzima ukuzilawula.Ummbila uhlwanyelwa ngaphambi kukabhontshisi wesoya, futhi ukusetshenziswa kwama-herbicides kufanele "kuvalwe futhi kuhlanganiswe".Ngemuva kokuhlwanyela nangaphambi kokutshala, inhlabathi kufanele ivalwe nge-metolachlor (noma i-acetochlor)+thiofensulfuron methyl namanye ama-agent.Uma kunokhula ensimini ngaphambi kokuhlwanyela, insimu ingafafazwa ngesifutho se-glyphosate;Uma umphumela wokuvala umhlabathi ungalungile futhi kudingeka ukwelashwa kwesifutho sesiqu neqabunga, i-nicosulfuron methyl+chlorofluoropyranoxyacetic acid (noma i-dichloropyridic acid, i-methimaxone) ingasetshenziswa ukuqondisa isiqu nesifutho samaqabunga (endaweni yokutshala ummbila) endaweni yesithathu. esigabeni sesihlanu seqabunga lezithombo zommbila.

Ezinsukwini ezintathu ngaphambi kokuhlwanyela kukabhontshisi wesoya, isifutho esiqondisayo se-glyphosate sasisenziwa ensimini.Ngemva kokuhlwanyela, ngaphambi kokuba kutshalwe izithombo, izibulala-zinambuzane ezifana ne-promethazine (noma i-acetochlor)+thiophensulfron zikhethwa ukuze zelashwe inhlabathi.Uma umphumela wokuvala umhlabathi ungalungile futhi udinga ukwelashwa ngesifutho sesiqu namaqabunga, i-quinclovir

(2) Ukutshala phakathi kwebhande likabhontshisi wesoya nommbila

Emfuleni ophuzi, emfuleni i-Huaihai, indawo emaphakathi nephansi yoMfula i-Yangtze, nasezifundeni ezisenyakatho-ntshonalanga, ubhontshisi wesoya nommbila kuhlwanyelwa kanyekanye.Ukusetshenziswa kweimithi yokubulala ukhula Ngokuyinhloko kusekelwe ekwelashweni kokuvalwa kwenhlabathi ngaphambi kwezithombo ngemva kokuhlwanyela, okudingeka ukuthi kuqedwe phakathi kwezinsuku ezi-2 ngemva kokuhlwanyela.Umhlabathi uvalwa ngama-ejenti afana ne-promethamide (noma i-metolachlor, i-acetochlor)+azosulfochlor (noma i-thiophenuron).Lapho inhlabathi yasensimini lapho isivuno sangaphambili singukolweni ivalwa ngomuthi wokubulala ukhula, kungcono kakhulu ukulima nge-rotary ukuze kuqedwe izinhlanga, kudale umswakama, bese uhlwanyela futhi ugcobe umuthi ngaphambi kokutshala;Emasimini okutshala okuqondile anezinhlanga zikakolweni, kuyadingeka ukwandisa ukusetshenziswa kwamanzi nge-mu ngayinye, futhi uma izimo zivuma, ukuchelela ngesikhathi kufanele kwenziwe ngemuva kokufakwaizibulala-zinambuzane;Ezindaweni ezomile nezinomoya njengasenyakatho-ntshonalanga, kungcono ukuhlanganisa umhlabathi emva kokufakaimithi yokubulala ukhula, nezindawo zamanzi ngesikhathi lapho izimo zivuma.

Uma umphumela wokuvala umhlabathi ungalungile futhi nokwelashwa kwesifutho seqabunga lesiqu kudingekile, kungasetshenziswa esigabeni samaqabunga ama-3 ~ 5 ngemva kwesithombo sombila, isigaba samaqabunga angu-2 ~ 3 kabhontshisi wesoya, isigaba samaqabunga angu-2 ~ 5 sokhula. .Ngokwezimo zotshani bendawo, i-nicosulfuron (noma i-oxazolone)+bentazone (noma i-cloflupyroxyacetic acid) Ensimini kabhontshisi wesoya, i-quinoxal (noma i-flumetafop-p-ethyl)+esebenza kahle kakhulu i-flumetafop-p-ethyl)+dimethasone (noma i-ethyl flumetafop-ethyl) isetshenziselwa isiqu neqabunga. i-directional spray weeding (amakhethini angokwenyama asetshenziselwa ukuhlukanisa ummbila nobhontshisi wesoya).Esigabeni sakamuva, ukhula okunzima ukululawula lungasuswa mathupha.
