Phambi kokugalela ukhula, injongo yokuhlakula kukuthintela ukhula ukuba lungaphumi emhlabeni kwangethuba.Inokuthintela imbewu yokhula engafunekiyo ukuba intshule phambi kokuntshula, ngoko iluncedo ekulweni ukhula kwingca, iibhedi zeentyatyambo kunye nakwizitiya zemifuno.
Eyona mveliso ilungileyo yokutshabalalisa ukhula iya kwahluka, kuxhomekeke kubungakanani bendawo efuna ukunyangwa kunye nohlobo lokhula umlimi afuna ukulubulala.Kwangaphambili, funda into omawuyijonge xa ​​uthenga imichiza yokutshabalalisa ukhula ngaphambi kokuntshula, kwaye ufumanise ukuba kutheni ezi mveliso zilandelayo zinokunceda ukukhusela ukhula oluyingozi kulo nyaka.
Imichiza yokutshabalalisa ukhula yangaphambi kokuhluma ifaneleke kakhulu kwingca kunye nezitiya apho kuye kwasekwa ingca nezityalo ezifanelekileyo.Noko ke, abalimi abafanele basebenzise ezi mveliso xa beceba ukutyala imbewu eluncedo, njengokutyatyamba kwembewu okanye ukutyala imifuno okanye ukutyala engceni.Ezi mveliso ziyahluka kwifom, amandla kunye nodidi lwezithako.Uninzi lwazo lubizwa ngokuba “zii-herbicides.”Funda ukuze ufumanise ngakumbi malunga nezi kunye neminye imiba ebalulekileyo ekufuneka uyiqwalasele xa ukhetha owona mchiza ubalaseleyo waphambi kokuhluma.
Zimbini iindlela eziphambili zokutshabalalisa ukhula kwangaphambi kokuvela: ulwelo kunye negranular.Nangona zonke zisebenza ngendlela efanayo (ngokuthintela ukhula ukuba lungantshuli emhlabeni), abanini-mhlaba kunye nabasebenzi bezitiya banokukhetha ukusebenzisa enye indlela ngaphezulu kwenye.Zombini ezi ntlobo ziya kunceda ekunciphiseni imfuno yokususa ukhula ngesandla.
Ngokungafaniyo nemichiza yokutshabalalisa ukhula emva kokuhluma, imichiza yokutshabalalisa ukhula ngaphambi kokuhluma ayijoliswanga kwiintlobo ezahlukeneyo zezityalo, kodwa kumanqanaba ahlukeneyo okukhula.Iya kuthintela imbewu ekuphuhliseni iingcambu okanye amahlumela ngaphambi kokuvela, kodwa ayiyi kuphazamisa iingcambu zezityalo ezinkulu.Ngokufanayo, imichiza yokutshabalalisa ukhula yangaphambi kokuhluma ayisayi kubulala iingcambu zokhula olungapheliyo olunokuba phantsi komhlaba, njengokhula olujikelezayo okanye ukhula lomlingo.Oku kunokubangela ukubhideka kubalimi, ababona ukhula luvela emva kokufaka imichiza yokutshabalalisa ukhula phambi kokuhluma.Ukuze kupheliswe ukhula olungapheliyo, kungcono ukubalinda ukuba luphume emhlabeni ngaphambi kokuba luphathwe ngokuthe ngqo ngemichiza yokutshabalalisa ukhula emva kokuvela.
Nangona imichiza yokutshabalalisa ukhula yaphambi kokuhluma ithintela uninzi lwembewu ukuba ingantshuli, enye imbewu yokhula (efana ne-verbena) inokusinda kwiintlobo ezithile ezibuthathaka zokutshabalalisa ukhula phambi kokuhluma.Ke ngoko, abavelisi bahlala bedibanisa ezimbini okanye ngaphezulu kwezi ntlobo zilandelayo zemichiza yokutshabalalisa ukhula kwimveliso enye.
Imichiza yokutshabalalisa ukhula phambi kokuhluma yenza umqobo emhlabeni ukuthintela ukuba imbewu yokhula ingantshuli ngempumelelo.Iimveliso eziqhelekileyo zinokukhusela indawo kwi-1 ukuya kwiinyanga ezi-3, kodwa ezinye iimveliso zinokubonelela ngamaxesha amade olawulo.Abavelisi abaninzi bacebisa ukuba basebenzise iimveliso zokutshabalalisa ukhula entlakohlaza xa iintyatyambo zeforsythia ziqala ukunyamalala entlakohlaza, kwaye ziphinde zisetyenziswe ekwindla ukunqanda imbewu yokhula evuthelweyo ukuba ingantshuli.Nangona ukusetyenziswa kwezityalo zangaphambi kokuntshula akunakuthintela lonke ukhula ukuba lungantshuli, nokuba lusetyenziswa kube kanye ngonyaka, uninzi lwazo lunokupheliswa.
Xa isetyenziswa njengoko kuyalelwe, uninzi lweemveliso zokutshabalalisa ukhula zikhuselekile.Isitshixo sokwandisa ukhuseleko kukucwangcisa kwangaphambili kwaye ufake isicelo xa abantwana kunye nezilwanyana zasekhaya bengekho.
Ukuze ibe lukhetho lokuqala, imichiza yokutshabalalisa ukhula phambi kokuhluma kufuneka ithintele ukhula olwahlukeneyo ukuba lungantshuli kwaye lunike imiyalelo ekulula ukuyilandela.Nangona i-preemergence herbicide ingcono kakhulu iya kwahluka ngokuxhomekeke kwindawo yonyango (efana nengca okanye igadi yemifuno), kufuneka inqande iindidi zokhula ezinokuthi zifumaneke kule ndawo.Zonke ezi mveliso zilandelayo ziya kunciphisa ukhula lwezandla kwaye luncede ukuphepha unyango lokhula emva kokuvela.
Abo bafuna umchiza wokutshabalalisa ukhula osebenzayo wangaphambi kokuhluma ukuthintela i-verbena kwingca, iibhedi zeentyatyambo, kunye nezinye iibhedi zokutyala kunye nemida, konke abakufunayo yi-Quali-Pro Prodiamine 65 WDG yokutshabalalisa ukhula kwangaphambili.Le mveliso yomgangatho wobuchwephesha ine-5-pound yegranular concentrate.Yenzelwe ukuyihlambulula kwaye iyitshize kwingca, phantsi kwemithi, namatyholo namatyholo kusetyenziswa isitshizi sempompo.
Ukongeza ekulawuleni i-horsegrass, oku kuhluma kwangaphambili kunokulawula nolunye ukhula oluyinkathazo, kuquka isiqhumiso, i-duckweed, kunye ne-euphorbia.Ipropylenediamine sisithako esisebenzayo;ngeziphumo ezilungileyo, sebenzisa le mveliso entwasahlobo nasekwindla.
Ukusebenzisa imichiza yokutshabalalisa ukhula kwigadi ye-Miracle-Gro kunokunciphisa imisebenzi yokulukhula ngaphandle kokuchitha imali eninzi.Le bud ye-granular pre-emergence bud ivela kumenzi owaziwayo, kwaye okona kubaluleke kakhulu, ixabiso layo lifanelekile.Umphezulu we-shaker efanelekileyo ufakwe kwi-tank yamanzi ye-5-pounds, enokuthi isasaze ngokulula iinqununu ezijikeleze izityalo ezikhoyo.
Isithinteli sokhula se-Miracle-Gro sisebenza kakuhle xa sisetyenziswe kwangoko ngexesha lokukhula kwaye sinokuthintela imbewu yokhula ukuba ingantshuli ukuya kutsho kwiinyanga ezintathu.Ingasetyenziselwa kwiibhedi zeentyatyambo, amatyholo kunye nemifuno yemifuno, kodwa ayikhuthazwa ukulawula ukhula kwi-lawn.
