Ixesha elifanelekileyo lokugalela imichiza yokutshabalalisa ukhula kusemva kwentsimbi yesi-6 ngokuhlwa.Ngenxa yobushushu obuphantsi kunye nokufuma okuphezulu ngeli xesha, ulwelo luya kuhlala kumagqabi okhula ixesha elide, kwaye ukhula luyakwazi ukufunxa ngokupheleleyo izithako ze-herbicide.Kunenzuzo ekuphuculeni umphumo we-weeding, kwaye kwangaxeshanye, ukukhuselwa kwembewu yengqolowa kunokuphuculwa, kwaye i-phytotoxicity ayilula ukuba yenzeke.

Ugalela nini imichiza yokutshabalalisa ukhula emva kwezithole zombona?

1. Ngenxa yokuba i-post-emergence herbicide itshizwa, kuthatha iiyure ezi-2-6 ngenkqubo yokufunxa.Kwezi yure zi-2-6, ingaba isiphumo se-herbicide sifanelekile ngokuqhelekileyo sinxulumene ngokusondeleyo nobushushu kunye nokufuma komoya.Tshiza kusasa, okanye emini nasemva kwemini xa imozulu yomile.

2. Ngenxa yobushushu obuphezulu, ukukhanya okuqinileyo, kunye nokuguquguquka okukhawulezileyo kweyeza ezingamanzi, iyeza lolwelo liya kuba ngumphunga kungekudala emva kokutshiza, ukuze inani le-herbicide elingena ukhula lilinganiselwe, nto leyo eya kukhokelela ekufunxeni ngokwaneleyo, ngaloo ndlela kuchaphazela ukhula. isiphumo sokutshabalalisa ukhula.Xa utshiza ngexesha lobushushu obuphezulu kunye nesomiso, izithole zombona nazo zixhomekeke kwi-phytotoxicity.

3. Ixesha elifanelekileyo lokutshiza lisemva kwentsimbi yesi-6 ngokuhlwa, kuba ngeli xesha, ubushushu buphantsi, ukufuma kuphezulu, ulwelo luhlala kumagqabi okhula ixesha elide, kwaye ukhula lunokufunxa ngokupheleleyo. izithako zokutshabalalisa ukhula., inceda ekuqinisekiseni umphumo we-weeding, kwaye iyeza lokuhlwa lingaphinda liphucule ukhuseleko lwezityalo zombona, kwaye akulula ukwenza i-phytotoxicity.

4. Ekubeni uninzi lwe-post-emergence herbicides kwi-corn yi-nicosulfuron-methyl, ezinye iintlobo zombona zivakalelwa kule nxalenye kwaye zithandwa kwi-phytotoxicity, ngoko ke ayifanelekanga ukuba amasimi ombona atyale umbona omnandi, i-waxy corn, i-Denghai series kunye nezinye. iintlobo zokutshizwa , ukuphepha i-phytotoxicity, kwiintlobo ezintsha zombona, kuyimfuneko ukuvavanya kwaye emva koko ukhuthaze.

Indlela yokusebenzisa imichiza yokutshabalalisa ukhula emva kokuvela kumbona?

1. Jonga ubungakanani bengca

1

(2) Ngenxa yokuba ingca incinci kakhulu, akukho ndawo yamayeza, kwaye umphumo wokulukhula awufanelekanga.Ubudala bengca obungcono kakhulu ngamagqabi ama-2 kunye nentliziyo e-1 ukuya kumagqabi ama-4 kunye nentliziyo ye-1.Ngeli xesha, ukhula lunendawo ethile yokufaka isicelo.Ukuchasana nokhula akukhulu, ngoko umphumo wokukhula ungcono.

2. Iindidi zombona

Ngenxa yokuba uninzi lwemichiza yokutshabalalisa ukhula emva kokuhluma kombona yi-nicosulfuron-methyl, ezinye iintlobo zombona zinovelwano kweli candelo kwaye ziqhelekile kwi-phytotoxicity, ngoko ke akunakwenzeka ukutshiza amasimi ombona apho umbona oswiti, umbona onama-waxy, uthotho lweDenghai kunye nezinye iintlobo zikhuliswa.Ukuvelisa i-phytotoxicity, iintlobo ezintsha zombona kufuneka zivavanywe ngaphambi kokunyuswa.

3. Ingxaki yokuxuba amayeza okubulala izitshabalalisi

Amayeza e-Organophosphorus akufunekanga atshizwe iintsuku ezisi-7 phambi nasemva kokutshiza izithole, kungenjalo kulula ukwenza i-phytotoxicity, kodwa inokuxutywa ne-pyrethroid insecticide.Iyeza lizalise intliziyo.

4. Ukumelana nokhula ngokwalo

Kwiminyaka yakutshanje, amandla okhula okumelana noxinzelelo aphuculwe.Ukuze ugweme ukuvela kwamanzi amaninzi emzimbeni, ukhula alukhuli kangako kwaye lomelele, kodwa lukhula lube ngwevu kwaye lube lufutshane, kwaye iminyaka yengca yokwenyani ayincinci.Ukhula lugqunywe kakhulu ngefluff encinci emhlophe kuwo wonke umzimba ukunciphisa ukuphuma kwamanzi.
