2. Izinyathelo zobuchwepheshe

(1) Ubhontshisi wesoya kanye neribhoni lommbila

Esifundeni esiseningizimu-ntshonalanga, imvula ina kakhulu, futhi kunezinhlobo eziningi zokhula, okunzima ukuzilawula.Ummbila utshalwa ngaphambi kukabhontshisi wesoya futhi ukusetshenziswa kwe-herbicide kufanele "kubulawe kuhlangene".Ngemva kokuhlwanyelwa kommbila, sebenzisa i-metolachlor (noma i-acetochlor) + i-thifensulfuron-methyl ukuze uvale inhlabathi.Uma kukhona ukhula ensimini ngaphambi kokuba ummbila uhlwanyelwe, ungasebenzisa i-glufosinate-ammonium spray;umphumela wokuvala umhlabathi awulungile Uma kudingeka ukwelashwa kwesifutho sesiqu nesamaqabunga, i-nicosulfuron + fluroxypyr (noma i-clopyralid, i-bentazone) ingasetshenziswa ukuze iqondise (indawo yokutshala ummbila) isiqu kanye nesifutho samaqabunga esigabeni sesi-3 ukuya kwesesihlanu ngemva kwezithombo zombila.

Ezinsukwini ezintathu ngaphambi kokuhlwanyela kukabhontshisi wesoya, iglufosinate yakhethwa ukuze kufafazwe ngendlela emigqeni engenalutho ensimini.Ngemuva kokuhlwanyela nangaphambi kwezithombo, inhlabathi ivalwa ngezibulala-zinambuzane ezifana ne-metolachlor (noma i-acetochlor) + thifensulfuron-methyl.Uma umphumela wokuvala umhlabathi ungalungile futhi kudingeka ukufafazwa kweziqu namaqabunga, i-quizalofop-pp (noma i-high-efficiency fluroxyfop-pp, fluazifop-pp, clethodim) + B Carboxyfluorfen (noma i-bentazone) eqondiswe (indawo yokutshala ubhontshisi wesoya) isiqu kanye isifutho seqabunga.

(2) Ubhontshisi wesoya kanye neribhoni lommbila

E-Huanghuaihai, indawo ephakathi nendawo ephansi yoMfula i-Yangtze, kanye neNyakatho-ntshonalanga yeChina, ubhontshisi wesoya nommbila kuhlwanyelwa ngasikhathi sinye, futhi ama-herbicides asetshenziswa ikakhulukazi ngemuva kokuhlwanyela kanye nokwelashwa kokuvala umhlabathi ngaphambi kokuvela, okudingeka ukuthi kuqedwe ngaphakathi kwe-2 izinsuku emva kokuhlwanyela.Ukuvalwa komhlabathi kwenziwa kusetshenziswa i-metolachlor ecwengiwe (noma i-metolachlor, i-acetochlor) + i-fensulfame (noma i-thifensulfuron-methyl) namanye ama-ejenti.Uma inhlabathi ivalwe ngama-herbicides ensimini lapho izinhlanga zangaphambili zingukolweni, kungcono ukulima ngokujikeleza ukuze kukhishwe izinhlanga, kudale umswakama, bese kuhlwanyela futhi kufakwe izibulala-zinambuzane ngaphambi kokutshala;emasimini lapho izinhlanga zikakolweni zisakazwa ngokuqondile, kuyadingeka ukwandisa ukusetshenziswa kwamanzi ngemu ngayinye, futhi kufakwe izibulala-zinambuzane uma kungenzeka.Ngemva kwalokho, amanzi ngesikhathi;ezindaweni ezinesomiso nezivunguvungu zesihlabathi njengaseNyakatho-ntshonalanga, kungcono ukuhlanganisa inhlabathi ngemva kokufakwa kwemithi yokubulala ukhula, namanzi ngesikhathi lapho izimo zivuma.

Lapho umphumela wokuvalwa kwenhlabathi ungalungile futhi kudingeka ukwelashwa kwesifutho sesiqu nesamaqabunga, kungasetshenziswa esigabeni samaqabunga ama-3-5 ngemuva kwezithombo zommbila, ubhontshisi wesoya ongu-2-3 esigabeni samaqabunga amathathu, kanye nokhula ku-2-5. isigaba seqabunga.Ngokwezimo zotshani zendawo, ummbila ungakhethwa.I-Nicosulfuron (noma i-oxaflumezone) + i-bentazone (noma i-fluroxypyr), namasimu kabhontshisi wesoya akhetha i-quizalofop-p-ethyl (noma i-fluroxyfop esebenza kahle kakhulu) + i-bentazone (noma i-fluroxyfen-ethanol) ) Ukufafaza okuqondisayo kwesiqu kweqabunga ukuze kukhishwe ukhula (sebenzisa amakhethini abonakalayo ukuze uhlukanise ummbila nobhontshisi wesoya wokufafaza).Esigabeni sakamuva, ukhula okunzima ukululawula lungasuswa mathupha.
