Ukhula lonyaka zizityalo ezigqibezela umjikelo wobomi bazo—ukususela ekuntshuleni ukuya kwimveliso yembewu nokufa—kwisithuba sonyaka omnye. Ziyakwazi ukufakwa kwiinyanga zasehlotyeni kunye nobusika bonyaka ngokusekelwe kwixesha labo lokukhula. Nantsi imizekelo eqhelekileyo:
Ukhula loNyaka lwasehlotyeni
Ukhula lonyaka lwasehlotyeni luhluma entwasahlobo okanye ekuqaleni kwehlobo, lukhule ngexesha leenyanga ezifudumeleyo, kwaye luvelise imbewu ngaphambi kokuba lufe ekwindla.
IRagweed eqhelekileyo (Ambrosia artemisiifolia)
I-Ambrosia artemisiifolia, enamagama aqhelekileyo i-ragweed, i-ragweed yonyaka, kunye ne-ragweed ephantsi, luhlobo lwe-Ambrosia eyinzalelwane kwimimandla yaseMelika.
Ikwabizwa ngamagama aqhelekileyo: umhlonyane waseMelika, i-bitterweed, i-blackweed, i-carrot weed, i-hay fever weed, umhlonyane waseRoma, i-ragweed emfutshane, i-stammerwort, i-stickweed, i-tassel weed.
Inkcazo: Inamagqabi alobe ngokunzulu kwaye ivelisa iintyatyambo ezincinci eziluhlaza ezijika zibe yimbewu efana ne-burr.
Indawo yokuhlala: Ifumaneka kumhlaba ophazamisekileyo, emasimini, nasemacaleni eendlela.
Lambsquarters (Chenopodium album)
Icwecwe leChenopodium sisityalo sonyaka esikhula ngokukhawuleza kusapho lwesityalo seAmaranthaceae. Nangona isityalo sihlakulwa kweminye imimandla, kwezinye iindawo sigqalwa njengokhula. Amagama aqhelekileyo abandakanya iikota zegusha, i-melde, i-goosefoot, isipinatshi sasendle kunye ne-fat-hen, nangona ezi zimbini zokugqibela zikwasetyenziswa kwezinye iintlobo ze-Chenopodium ye-genus, ngenxa yeso sizathu isoloko ibonakaliswe njenge-goosefoot emhlophe. kuMntla weIndiya, kunye neNepal njengesityalo sokutya esibizwa ngokuba yibathua.
Inkcazo: Isityalo esithe tye esinamagqabi abunjiweyo, amaxesha amaninzi sineengubo ezimhlophe ngaphantsi.

Inkcazo: Ingca enentloko yembewu ene-bristly, cylindrical; ibandakanya iindidi ezifana nomsila wempungutye omkhulu kunye nomsila wempungutye oluhlaza.
Indawo yokuhlala: Ixhaphakile emasimini, kwiigadi, nakwindawo eziyinkunkuma.
Ukhula loNyaka lwasebusika
Ukhula lonyaka lwasebusika luntshula ekwindla, ubusika bukhula njengezithole, lukhula entwasahlobo, kwaye luvelise imbewu ngaphambi kokufa ekuqaleni kwehlobo.
Chickweed (Stellaria media)
Inkcazo: Isityalo esikhulayo esincinci esineentyantyambo ezimhlophe ezimile okwenkwenkwezi kunye namagqabi agudileyo, a-oval.

Yeyiphi imichiza yokutshabalalisa ukhula enokusetyenziswa ukubulala olu khula?
Uhlobo oluqhelekileyo lomchiza wokutshabalalisa ukhula olusetyenziswa ukususa ukhula loNyaka luQhagamshelana nemichiza yokutshabalalisa ukhula. (Yintoni umchiza wokutshabalalisa ukhula?)
Imichiza yokutshabalalisa ukhula luhlobo oluthile lwesitshabalalisi esibulala kuphela iindawo zesityalo ezidibana nazo ngqo. Azishukumi (zifudukele) phakathi kwesityalo ukuze zifikelele kwezinye iindawo ezinjengeengcambu okanye amahlumela. Ngenxa yoko, le michiza yokutshabalalisa ukhula isebenza kakhulu kukhula lonyaka kwaye ingasebenzi kakuhleezingapheliyoizityalo ezineengcambu ezibanzi.
Imizekelo yeMichiza yokutshabalalisa ukhula
IParaquat:
Indlela yokuSebenza: inqanda iphotosynthesis ngokuvelisa iintlobo zeoksijini esebenzayo ebangela umonakalo wenwebu yeseli.
Usetyenziso: Isetyenziswa kakhulu kwezolimo ukutshatyalaliswa kokhula kwizityalo ezahlukeneyo kunye neendawo ezingavuniyo. Isebenza kakhulu kodwa inetyhefu kakhulu, ifuna ukuphathwa ngononophelo.
I-Diquat:
Indlela yokuSebenza: Ngokufana neparaquat, iphazamisa i-photosynthesis kwaye ibangele umonakalo okhawulezayo we-membrane yeseli.
Usetyenziso: Isetyenziselwa ukunqunyulwa kwezityalo phambi kokuvuna, ekutshatyalalisweni kokhula emanzini, nakulawulo lwezityalo kwimizi-mveliso.
I-Pelargonic acid:
Indlela yokuSebenza: Iphazamisa iimbumba zeeseli ezibangela ukuvuza kunye nokufa kweeseli ngokukhawuleza.
Usetyenziso: Ixhaphakile kulimo oluphilayo kunye nokulima egadini ukulawula amagqabi abanzi kunye nokhula olunengca. Ayinatyhefu encinci ebantwini nasezilwanyaneni xa ithelekiswa nemichiza yokudibanisa ukhula.
Ukusetyenziswa:
Imichiza yokutshabalalisa ukhula isetyenziselwa ukutshabalalisa ukhula olukhawulezayo, olusebenzayo lonyaka.
Zidla ngokusetyenziswa kwiimeko apho kufuneka ukutshatyalaliswa kokhula ngokukhawuleza, njengaxa kugalelwe phambi kokuvuna okanye ukususa amasimi phambi kokutyala.
Zikwasetyenziswa nakwiindawo ezingezizo izityalo ezifana neziza zemizi-mveliso, ecaleni kwendlela, nakwiindawo ezisezidolophini apho kufuneka kulawuleke ngokupheleleyo uhlaza.
Isantya sesenzo:
Le michiza yokutshabalalisa ukhula ikholisa ukusebenza ngokukhawuleza, kunye neempawu ezibonakalayo ezivela kwiiyure ezimbalwa ukuya kwiintsuku ezimbalwa emva kokufakwa.
Ukunqunyulwa okukhawulezileyo kunye nokufa kweendawo ezidityanisiweyo zesityalo zixhaphakile.
Indlela yokwenza:
Ukuqhagamshelana nemichiza yokutshabalalisa ukhula isebenza ngokonakalisa okanye ukutshabalalisa izicubu zezityalo ezizichukumisayo. Ukuphazamiseka kwenzeka ngokuqhelekileyo ngokuphazamiseka kwe-membrane, ukuvinjelwa kwe-photosynthesis, okanye ukuphazamiseka kwezinye iinkqubo zeselula.
Izinto eziluncedo:
Isenzo esiKhawulezayo: Luphelisa ngokukhawuleza ukhula olubonakalayo.
Iziphumo zangoku: Iluncedo kwiimeko ezifuna ukususwa kokhula ngoko nangoko.
Intsalela yoMhlaba encinci: Amaxesha amaninzi aziqhubeki kwindalo esingqongileyo, nto leyo eyenza ukuba zibe lukhetho olulungileyo lokutshabalalisa ukhula phambi kokutyala.
Siyi aumthengisi weedkiller osekwe eTshayina. Ukuba awuqinisekanga ngendlela yokujongana nokhula, singakucebisa ngemichiza yokutshabalalisa ukhula kwaye sikuthumelele iisampulu zasimahla ukuze uzame. Sijonge phambili ukuva kuwe!
