Ngaphambi kokufaka ukhula, umgomo wokukhipha ukhula ukuvimbela ukhula ukuba luphume emhlabathini ngokushesha ngangokunokwenzeka.Ingavimbela imbewu yokhula engadingeki ukuba iqhume ngaphambi kokumila, ngakho-ke ingumlingani onenzuzo ngokumelene nokhula otshanini, imibhede yezimbali ngisho nezingadi zemifino.
Umkhiqizo ongcono kakhulu wokubulala ukhula ngaphambi kokuhluma uzohluka, kuye ngobukhulu bendawo edinga ukwelashwa kanye nohlobo lokhula umlimi afuna ukulubulala.Kusenesikhathi, funda ukuthi yini okufanele uyibheke lapho uthenga ama-herbicides angaphambi kokuhluma, futhi uthole ukuthi kungani le mikhiqizo elandelayo ingasiza ekuvimbeleni ukhula oluyingozi kulo nyaka.
Imithi yokubulala ukhula ngaphambi kokuhluma ifaneleka kakhulu etshanini nasezingadini lapho sekusungulwe khona utshani nezitshalo ezifanele.Nokho, abalimi akufanele basebenzise le mikhiqizo lapho behlela ukutshala imbewu ezuzisayo, njengokuqhakaza kwembewu noma ukutshala imifino noma ukuhlwanyela otshanini.Le mikhiqizo iyahlukahluka ngesimo, amandla kanye nohlobo lwezithako.Eziningi zibizwa ngokuthi “ama-herbicides.”Qhubeka ufunde ukuze uthole okwengeziwe ngalezi nezinye izici ezibalulekile okufanele uzicabangele lapho ukhetha umuthi ongcono kakhulu wokubulala ukhula ngaphambi kokuvela.
Kunezinhlobo ezimbili eziyinhloko zama-preemergence herbicides: uketshezi kanye ne-granular.Nakuba zonke zisebenza ngendlela efanayo (ngokuvimbela ukhula ukuthi lungaphumi emhlabathini), abanikazi bezindlu kanye nabalimi bangase bakhethe ukusebenzisa uhlobo olulodwa kunolunye.Zombili izinhlobo zizosiza ekunciphiseni isidingo sokususa ukhula ngesandla.
Ngokungafani nemithi eminingi yokubulala ukhula ngemva kokuvela, imithi yokubulala ukhula ngaphambi kokuhluma ayihloselwe izinhlobo ezahlukene zezitshalo, kodwa ezigabeni zokukhula ezihlukene.Kuzovimbela imbewu ukuthi ikhule ibe izimpande noma amahlumela ngaphambi kokumila, kodwa ngeke ilimaze izimpande zezitshalo ezinkulu.Ngokufanayo, imithi yokubulala ukhula ngaphambi kokuhluma ngeke ibulale izimpande zokhula olungapheli okungenzeka lube ngaphansi kwenhlabathi, njengokhula oluvunguzayo noma ukhula oluyimilingo.Lokhu kungabangela ukudideka kubalimi, ababona ukhula luvela ngemva kokufaka imithi yokubulala ukhula ngaphambi kokuhluma.Ukuze kuqedwe ukhula olungapheli, kungcono ukulinda ukuthi luphume emhlabathini ngaphambi kokuluphatha ngokuqondile ngama-herbicides ngemva kokuvela.
Nakuba ama-herbicides amaningi angaphambi kokuhluma avimbela iningi lembewu ekukhuleni, ezinye izimbewu zokhula (njenge-verbena) zingase ziphile ezinhlotsheni ezithile ezibuthakathaka zemithi yokubulala ukhula ngaphambi kokuhluma.Ngakho-ke, abakhiqizi bavame ukuhlanganisa ezimbili noma ngaphezulu izinhlobo ezilandelayo zemithi yokubulala ukhula ngaphambi kokuvela komkhiqizo owodwa.
Ama-pre-emergency herbicides akha umgoqo emhlabathini ukuze imbewu yokhula ingaqhume ngempumelelo.Imikhiqizo evamile ingavikela indawo inyanga engu-1 ukuya kwezingu-3, ​​kodwa eminye imikhiqizo inganikeza nezikhathi zokulawula ezinde.Abakhiqizi abaningi batusa ukusebenzisa imikhiqizo yokubulala ukhula esanda kuvela entwasahlobo lapho ukuqhakaza kwe-forsythia kuqala ukufiphala entwasahlobo, bese kuphinda kusetshenziswe ekwindla ukuze kuvinjwe imbewu yokhula evuthelwe ukuthi ingaqhumi.Nakuba ukusetshenziswa kwezitshalo zangaphambi kokuhluma kungase kungavimbeli lonke ukhula ekuqhumeni, ngisho noma zisetshenziswa kanye kuphela ngonyaka, eziningi zazo zingaqedwa.
Uma isetshenziswa ngendlela eyalelwe ngayo, imikhiqizo eminingi yokubulala ukhula ngaphambi kokuvela kwayo iphephile.Ukhiye wokukhulisa ukuphepha ukuhlela kusenesikhathi futhi usebenzise lapho izingane nezilwane ezifuywayo zingekho.
Ukuze kube yisinqumo sokuqala, imithi yokubulala ukhula ngaphambi kokuhluma kufanele ivimbele ukhula oluhlukahlukene ukuthi lungamili futhi inikeze imiyalelo okulula ukuyilandela.Nakuba i-preemergence herbicide engcono kakhulu izohluka ngokuya ngendawo yokwelashwa (njengotshani noma ingadi yemifino), kufanele imise izinhlobo zokhula okungenzeka zitholakale kulezi zindawo ezithile.Yonke le mikhiqizo elandelayo izonciphisa ukususa ukhula ngesandla futhi isize ukugwema ukwelashwa kokhula ngemva kokuvela.
Labo abafuna umuthi osebenzayo wangaphambi kokuhluma wokuvimbela i-verbena otshanini, imibhede yezimbali, neminye imibhede yokutshala nemingcele, abakudingayo kuphela i-Quali-Pro Prodiamine 65 WDG yokubulala ukhula ngaphambilini.Lo mkhiqizo wekhwalithi yobuchwepheshe unokugxiliswa kwe-granular okungamaphawundi angu-5.Yakhelwe ukuhlanjululwa futhi ifuthwe otshanini, ngaphansi kwezihlahla, nasezihlahleni nasezihlahleni kusetshenziswa isifutho sepompo.
Ngaphezu kokulawula utshani behhashi, lokhu kuhluma kungaphinda futhi kulawule olunye ukhula olukhathazayo, okuhlanganisa impepho, i-duckweed, ne-euphorbia.I-Propylenediamine iyisithako esisebenzayo;ukuze uthole imiphumela engcono kakhulu, sebenzisa lo mkhiqizo entwasahlobo nasekwindla.
Ukusebenzisa i-miracle-Gro garden herbicide kunganciphisa imisebenzi yokukhipha ukhula ngaphandle kokuchitha imali eningi.Le bud yangaphambi kokuvela kwe-granular ivela kumkhiqizi owaziwayo, futhi okubaluleke kakhulu, intengo yayo inengqondo.Ingaphezulu le-shaker elilula lifakwa ethangini lamanzi elingamakhilogremu angu-5, elingasakaza kalula izinhlayiya ezizungeze izitshalo ezikhona.
Isivimbeli sokhula se-Miracle-Gro sisebenza kahle kakhulu uma sisetshenziswa ekuqaleni kwesikhathi sokukhula futhi singavimbela imbewu yokhula ukuthi ingamili kuze kube yizinyanga ezintathu.Ingasetshenziswa emibhedeni yezimbali, ezihlahleni nasezingadini zemifino, kodwa ayinconywa ukulawula ukhula otshanini.
