Isilawuli Sokukhula Kwe-Defoliant
I. Uhlolojikelele
I-Defoliant iyisilawuli sokukhula esingakhuthaza izitshalo ukuthi zichithe amaqabunga ekwindla, zifinyeze isikhathi sokukhula kwezitshalo, zithuthukise ukusebenza kahle kwe-photosynthesis yezitshalo, futhi zithuthukise ukumelana kwesitshalo ekucindezelekeni nokubanda. Indlela yokusebenza yama-defoliants ukulawula izinga lamahomoni angapheli, ukuguga amaqabunga, nokukhuthaza ukuchithwa. Ezitshalweni ezihlala endaweni yokushisa ephansi isikhathi eside, ukusetshenziswa okufanele kwama-defoliants nakho kungakhuthaza ngokuphumelelayo ukukhula nokuthuthukiswa kwazo.
II. Indlela efanele yokusebenzisa ama-defoliants
1. Umthamo
Umthamo wama-defoliants kufanele ulungiswe ngokuya ngezinhlobo zezitshalo ezahlukahlukene kanye nezimo zokukhula. Ngokuvamile, umthamo omkhulu we-defoliant odingwa isitshalo, ukhula uphakame uqonde, futhi umbala wamaqabunga ulula, umthamo we-defoliant osetshenziswayo uba mkhulu. Ngesikhathi esifanayo, lapho izinga lokushisa liphezulu, umthamo ovumelaniswe nezinga lokushisa ungenza i-defoliant iphumelele kakhulu.
2. Isikhathi sokusebenzisa
Ngaphambi kokusetshenziswa okusemthethweni kwama-defoliants, izinqolobane ezidingekayo noma umsebenzi wokulima kufanele wenziwe kuqala. Lokhu kuzokwenza izitshalo zifinyelele esimweni esihle kakhulu ngesikhathi sokukhula okunamandla, futhi ngemva kokusetshenziswa kwe-defoliant, izitshalo zingakwazi ukuzivumelanisa kangcono nezinguquko zemvelo, okuzuzisa ukukhula nempilo yezitshalo. Ama-Defoliants ngokuvamile asetshenziswa ekwindla, futhi isikhathi sokufaka kanye nesikhawu sohlobo ngalunye lwesitshalo kufanele kwehluke. Ngokuvamile, isikhathi sokufakwa kwama-defoliants kufanele sibe lapho izitshalo zenza imiqumbe futhi ziqala ukungena esiqongweni sokukhula. Ngaphambi kokusebenzisa ama-defoliants, kufanele kwenziwe uphenyo oludingekayo kanye nokugcinwa kwezinto, futhi izindlela zokusebenzisa ezifanele kufanele zenziwe kahle ukuze kugwenywe imiphumela emibi ezitshalweni.
3. Izinyathelo zokuphepha
Ngaphambi kokusebenzisa ama-defoliants, izinqolobane ezidingekayo noma umsebenzi wokwelapha kufanele wenziwe kuqala. Ngokuvamile, lo msebenzi wokwelapha uhlanganisa ukususwa kukadoti, ukubuna kanye nokwelashwa kwesakhiwo sezimpande. Ngaphezu kwalokho, imithetho yokukhula kwezitshalo kanye nezinguquko zonyaka kufanele ilandelwe, futhi izilawuli ezihlukene, imithamo nezindlela zokusetshenziswa kufanele zikhethwe ngokuvumelana nezimo zezulu ezihlukene, indawo nezinhlobo zezitshalo ukuze kuzuzwe umphumela omuhle kakhulu. Ngaphezu kwalokho, ngaphambi kokusebenzisa ama-defoliants, kufanele kuqinisekiswe ukuthi isimo sezitshalo sifanelekile futhi sisesimweni esihle kakhulu sokukhula. Uma kukhona ukungaphatheki kahle, yeka ukuyisebenzisa kusenesikhathi.

Ama-Defoliants ayisilawuli sokukhula esingakhuthaza izitshalo ukuthi zichithe amaqabunga ekwindla, zithuthukise ukusebenza kahle kwezitshalo ze-photosynthesis, futhi zithuthukise ukumelana nezitshalo ebunzimeni nasemakhazeni. Kodwa-ke, ukusebenzisa ama-defoliants ukulawula ukukhula kwezitshalo, kuyadingeka ukwazi umthamo ofanele, isikhathi sokusebenzisa kanye nezinyathelo zokuphepha ukuze uthole umphumela omuhle kakhulu.
