Ukutshala inhlanganisela yesoya kanye nebhande lommbila kuwukuthuthuka okusha kobuchwepheshe bendabuko bokuhlanganisa izitshalo, okubeka phambili izidingo eziphakemei-herbicideukukhetha okuhlukahlukene, isikhathi sokufaka isicelo, kanye nendlela yokufaka isicelo.Ukuze kumiswe ngokwesayensi ukusetshenziswa kobuchwepheshe bokubulala ukhula ekutshaleni okuhlanganisiwe kukabhontshisi wesoya kanye nebhande lommbila futhi kuthuthukiswe umphumela wokulawula, lolu hlelo lwakhiwe ngokukhethekile ukuze lusetshenziswe yizifunda ezihlukahlukene.

1. Isu lokuvikela nokulawula

Umgomo wokulawula okuphelele uyalandelwa ekutshaleni ubhontshisi wesoya kanye nebhande lommbila, futhi indima yezinyathelo zezolimo ezifana nokulima, i-rotary tillage, nokumboza ngefilimu yepulasitiki isetshenziswa ngokugcwele ukuze kuncishiswe ukuvela kokhula endaweni. insimu futhi unciphise ukucindezela kokukhula kwamakhemikhali.Ukusetshenziswa kwemithi yokubulala ukhula kufanele kuhambisane neqhinga lokusebenzisa “ukwelashwa kokuvala inhlabathi ngaphambi kokuhlwanyela ngemva kokuhlwanyela, kwengezwe ngokuma kwesiqu namaqabunga noma isifutho esikhethekile ngemva kokuhlwanyela”.Ngokwezici zezifunda ezihlukene nezindlela ezahlukene zokutshala, akudingekile ukuthi kubhekwe nje kuphela ukuphepha kokukhula kukabhontshisi nommbila esitshalweni samanje, kodwa futhi nokuphepha kwesitshalo esilandelayo kanye nokushintshashintsha kokutshala kwe-soya kanye nebhande lommbila ngonyaka olandelayo, futhi ngokwesayensi nangokunengqondokhetha i-herbicideizinhlobo nezindlela zokusebenzisa.

zivumelane nezinyathelo zomuntu ezimweni zendawo.Zonke izindawo kufanele zenze izinhlelo zobuchwepheshe zokulawula ukhula ngokusekelwe esikhathini sokutshala, indlela yokutshala, kanye nezinhlobo zokhula, zikhethe ngokwesayensi ezifanele.i-herbicide izinhlobo kanye nomthamo ngokusekelwe ezimweni zendawo, futhi wenze ukuhlukanisa kanye neziqondiso ezinembile.

Yelapha kusenesikhathi futhi welaphe abasebasha.Kufanele kuqalwe ukusetshenziswa kokwelashwa kwenhlabathi evaliwe ukuze kukhishwe ukhula ngemva kokuhlwanyela nangaphambi kokuhlwanyela ukuze kuncishiswe ingcindezi yokukhipha ukhula ngemva kokutshala.Ukukhipha izithombo ngemuva kokutshala kugxile ezigabeni zezithombo kanye nezithombo, okuyizigaba ezibalulekile zokulawula ukhula futhi zibe nemiphumela emihle yokukhula.

Iphephile futhi isebenza kahle.Izinhlobonhlobo zemithi yokubulala ukhula esetshenziselwa ukulawula ukhula kufanele iqinisekise ukusebenza kahle okuphezulu kanye nengozi ephansi, futhi iphephe ekukhuleni kwesitshalo samanje sikabhontshisi wesoya, ummbila, kanye nezitshalo ezizungezile, kuyilapho ingaphazamisi isitshalo esilandelayo.
