Ehlotyeni, izifo zengca zixhaphakile, kwaye ukugcinwa kwengca kubaluleke kakhulu. Imiba eqhelekileyo yokugcinwa kwengca kunye nolawulo ishwankathelwe ngolu hlobo lulandelayo:
Ukucheba ingca: Ubungakanani bokucheba: Umgaqo othi “1/3 yenani eliza kunqunyulwa” kufuneka ulandelwe, kwaye ukucheba kakhulu kufuneka kuthintelwe. Ubungakanani bokucheba ngalo lonke ixesha akufuneki kudlule i-1/3 yobude obupheleleyo beziqu namagqabi, kwaye iirhizomes akufuneki zonakaliswe. Ngaphandle koko, ukukhula okuqhelekileyo kwengca yotshani kuya kuchaphazeleka ngenxa yokungalingani phakathi kokukhula kweziqu namagqabi angaphezulu komhlaba kunye nokukhula kweengcambu ezingaphantsi komhlaba. Ke ngoko, ubungakanani bokucheba ingca kufuneka bulungiswe. Yiba ngqongqo ngayo. Ukuphakama kokucheba (ukuphakama kweengceba): Bubude obuthe nkqo bamasebe angaphezulu komhlaba emva kokucheba. Uhlobo ngalunye lwengca yotshani lunoluhlu lwalo oluthile lokuphakama kokucheba apho iziphumo zokucheba ingca ziya kufezekiswa khona. Xa ingaphantsi kobubanzi bokuphakama kokucheba, iingcambu ezininzi eziluhlaza kunye namagqabi ziya kususwa, okubangela ukuba iingcambu namagqabi ziqhekezwe, iingcambu ezindala zivele, kwaye nomhlaba uvele; xa iphezulu kunobubanzi bokuphakama kokucheba, ingca iya kuba mbalwa ngexesha loxinzelelo, kwaye ingca iya kuba mbalwa. Ityiwa lula lukhula, nto leyo ebangela ukuba ingca yengca ibe thambile, ithambe okanye ihlale, nto leyo eyenza kube nzima ukwenza indawo entle yotyani. Iingca zengca ezahlukeneyo zinyamezela ubude obahlukeneyo bokusika utyani ngenxa yeempawu zazo ezahlukeneyo zebhayoloji. Iingca zengca ezikhula zime nkqo, ezifana ne-bluegrass, i-tall fescue, njl.njl., azixhathisi kakhulu ekuchebeni utyani oluphantsi; iingca zengca ezine-stolons, ezifana ne-creeping bentgrass kunye ne-bermudagrass, ziyaxhathisa ekuchebeni utyani oluphantsi. Ingca yengca yesizini epholileyo ingena kwixesha lokuphumla elishushu kwaye ukumelana kwayo kuyancitshiswa, ngoko ke ukuphakama kweengca kufuneka konyuswe ngokufanelekileyo. Ubuninzi bokusika utyani kufuneka buchetywe kube kanye kwiiveki ezi-2-3. Xa ucheba utyani, qwalasela indlela yokucheba ukuthintela ukubonakala kwemicu enemibala eyahlukileyo yokukhanya nemnyama. Xa kuvela isifo, iiblade zomatshini wokusika utyani kufuneka zibulawe iintsholongwane xa ucheba utyani ukuthintela ukusasazeka kwesifo.
Ukuchumisa ingca: Xa ufaka isichumiso kwiingca ehlotyeni, sebenzisa isichumiso se-nitrogen ngononophelo kwaye wongeze isichumiso se-potassium. Ukuba isichumiso se-nitrogen asifakwa ehlotyeni, amagqabi engca yexesha elipholileyo aya kuba tyheli kwaye abe nokumelana okukhulu nezifo. Ukuba kufakwa isichumiso se-nitrogen eninzi kakhulu, kuya kubakho izifo ezinzulu kwaye umgangatho wengca uya kwehla kakhulu. Xa usebenzisa izichumiso, ungakhetha izichumiso ezihambelana nengca. Isichumiso esifanelekileyo esihambelana nengca asinakulungisa kuphela umlinganiselo we-nitrogen, i-phosphorus, i-potassium kunye nezinye izichumiso, kodwa sikwanayo nesixa esifanelekileyo se-nitrogen enyibilikayo emanzini kunye ne-nitrogen enganyibilikiyo emanzini. Idibanisa isantya kunye nokucotha ukulawula i-nitrogen ngokufanelekileyo. yokukhululwa. Izinto ezilandelelanayo zihlala zongezwa ngohlobo lwe-sulfates, kwaye ezinye zongeza izibulali-zinambuzane, iifungicides, njl.njl., ukuze ukuchumisa, ukubulala iintsholongwane kunye nokususwa kwezinambuzane kugqitywe ngexesha elinye.
Ukunkcenkceshela ngexesha elifanelekileyo: Misela ngokuchanekileyo ixesha lokunkcenkceshela ingca. Xa umbala wamagqabi engca utshintsha ukusuka ekubeni mhlophe ukuya kumnyama okanye umhlaba ujika ube mhlophe kancinci, ingca idinga ukunkcenkceshela. Kwingca ezivuthiweyo, amanzi kufuneka "ankcenkceshelwe kwangoko xa yomile kwaye icocekile kanye", ngelixa kwingca ezingekavuthwa, "incinci kufuneka inkcenkceshelwe amaxesha amaninzi" ukuqinisekisa ukukhula okuqhelekileyo kwengca. Ukunkcenkceshela kufuneka kwenziwe kusasa okanye ngokuhlwa xa kungekho moya okanye umoya ovuthuzayo ukunciphisa ixesha lokumanzi komphezulu wamagqabi, ngaloo ndlela kunciphisa amathuba esifo. Ukunkcenkceshela kufuneka kuphetshwe emini nasebusuku ehlotyeni. Ukunkcenkceshela emini kunokubangela ukutsha kwengca ngokulula, kwaye ukufuma okukhulu kuya kunciphisa izinga lokusetyenziswa kwamanzi okunkcenkceshela, ngoko ke ukunkcenkceshela emini kufuneka kuphetshwe. Ukunkcenkceshela ebusuku kuya kugcina ingca imanzi ubusuku bonke, nto leyo enokubangela izifo ngokulula.
Ukhula nezifo Ehlotyeni, ezinye izityalo ezinengca ezifana ne-crabgrass, i-foxtail grass, kunye ne-barnyard grass engceni zindala kakhulu. Ngexesha lokulawula, kufuneka kwandiswe i-dilution factor ye-herbicide. Iingca zexesha elipholileyo zichaphazeleka zizifo ezifana ne-Pythium wilt, i-sickle wilt, kunye ne-summer spot ngeli xesha lonyaka. Ngexesha lolawulo nolondolozo, kufuneka kunikwe ingqalelo ekutshizeni i-fungicide ekhuselayo i-Luan. Nje ukuba ingca isuleleke, ii-fungicides zonyango ezifana ne-Lvkang, i-Sujuqing, kunye ne-Xiabanol kufuneka zikhethwe ukuze kuthintelwe kwaye kulawulwe.
Ulawulo lweZinambuzane uJulayi no-Agasti ngamaxesha apho izinambuzane ezitya amagqabi ezifana neempungutye ze-meadow borer kunye ne-armyworms zonakalisa ingca, ngoko ke kufuneka kwenziwe uhlolo. Khetha i-Moth Borer Cleaner amaxesha angama-800 ukulawula ukutshiza, okukhuselekileyo kwaye akungcolisi okusingqongileyo. Ingazitshabalalisa ngokukhawuleza izinambuzane kwaye ikhusele iintshaba zemvelo. I-Diflubenzuron ingasetyenziselwa nokulawula.
