KukangaphiingcaUkulungiswa kwe-topdressing kuxhomekeke kumgangatho womhlaba osele ukho phantsi kwengca. Amanye amaqela egalufa anokutshintshwa kwe-top eluhlaza rhoqo emva kweeveki ezimbini, kodwa ungakhathazeki: emakhaya, nakubantu abanomhlaba owonakeleyo, kanye ngonyaka kwanele.
Izichumisi ezixutyiweyo zenitrogen, phosphorus, kunye nepotassium granular kufuneka zisetyenziswe ngexesha lokukhula. Ngokuqhelekileyo zisetyenziswa emva kokuthena nangaphambi kokunkcenkceshela ngokufafaza. Isichumisi esisisiseko ikakhulu sisichumisi sendalo, ekufuneka siboliswe ngokupheleleyo. Ubungakanani besichumisi esisetyenziswayo kwihektare nganye kufuneka bube ziitoni ezingama-75-110, kwaye i-superphosphate kufuneka ibe yi-300-750kg, enokuhlanganiswa nokulima umhlaba ukuze kusetyenziswe isichumisi.
Umlinganiselo we-nitrogen:phosphorus:potassium kufuneka ulawulwe kwi-5:4:3. Izinga lokusetyenziswa lilula kwaye lincinci kwixesha lempumelelo, kwaye ixesha elicothayo linamandla kunexesha lempumelelo, nto leyo enokunyusa ukuchumisa okungaphezulu kweengcambu. Ukuchumisa kunye nokunkcenkceshela kufuneka kuhambelane ngokusondeleyo ukuthintela umonakalo kwingca ebangelwa kukusetyenziswa okungafanelekanga. Ukusetyenziswa kwesichumiso sendalo akunakuphucula kuphela ukondleka komhlaba, kodwa kukwaphucula ukuvuleka komhlaba kunye nokuvuleka kwawo, kwaye kuncede neengca ukuba zisinde ebusika ngokukhuselekileyo.
Ingca yeTurf emantla ifanelekile ukuba ichumiswe kabini ngonyaka, ekuqaleni kwentwasahlobo nasekuqaleni kokwindla. Ukuchumisa kokuqala ekuqaleni kuka-Epreli (ukuchumisa okufanelekileyo) akunakwenza nje kuphela ingca jika ube luhlaza kwangaphambili, kodwa ukwanceda ngexesha lokupholisaingca yotshaniukuze kubuyiselwe umonakalo kwaye kutyebe utyani ngaphambi kokuba ukhula lonyaka luhlume; yenza isichumiso sesibini ngoSeptemba. Ukongeza ekwandiseni ixesha eliluhlaza ukuya ekupheleni kwekwindla nasebusika, inokukhuthaza ukukhula kwamasebe amatsha kunye neerhizomes kunyaka wesibini.
Ukuze kugcinwe imeko entle yomhlaba, kuhlale ixesha elide kuluhlaza, kwaye kuxhathiswe izifo nezinambuzane, kufuneka kubekho isondlo esithile. Ngoko ke, kuyimfuneko ukuqinisa i-extra-root topdressing kunye nokongeza ezinye izinto ezincinci ngaphandle kwe-N, i-P, kunye ne-K ukuze kuhlangatyezwane neemfuno zokukhula kwayo.
Kulawulo lolondolozo, kugxininiswa ekulawuleni amanzi kunye nesichumisi, ukunamathela entwasahlobo ukuthintela amabala, ukunamathela kwi-sunscreen yasehlotyeni, ukunamathela ekwindla nasebusika engceni ukuthintela umoya nokufuma. Ngokubanzi, fafaza amanzi kanye kusasa nangokuhlwa kwiveki e-1 emva kokuncamathisela ingca, kwaye ujonge ukuba utshani buxinene na, kwaye iingcambu zengca kufuneka zibe kufutshane nomhlaba wendwendwe. Fafaza amanzi kube kanye ngemini ngokuhlwa kwiveki ezi-2 emva kokuyifaka. Emva kweeveki ezi-2, kuxhomekeke kwixesha lonyaka kunye neemeko zemozulu, kudla ngokuthatha iintsuku ezi-2 ukuya kwezi-3 ukutshiza amanzi, ikakhulu ukufumisa.
Faka isichumiso kwiveki e-1 emva kokutyala ukuya kwiinyanga ezi-3, faka isichumiso kube kanye emva kwesiqingatha senyanga, fafaza ngesisombululo se-urea esingu-0.1% ~ 0.3% kunye nokunkcenkceshela, nciphisa ngaphambi kwaye ube mkhulu; kanye ngenyanga, i-urea engama-667m 2 ~ 3kg, emini yemvula Sebenzisa umatshini wokusika ingca ukusika ingca xa yonke ingca iphakame nge-8 ~ 10cm xa usasaza okanye usetyenziswa ngolwelo kwimozulu ecacileyo.
Ukhula luyasuswa kwangethuba emva kwesiqingatha senyanga emva kokutyala, kwaye ekupheleni kukaJanuwari, ukhula luqala ukukhula. Ukhula kufuneka lugrunjwe luze luqale iingcambu ngexesha, kwaye luxinaniswe emva kokugrunjwa ukuze kuthintelwe ukuchaphazela ukukhula kwengca ephambili. Ingca esandula ukutyalwa ngokubanzi ayinazo izinambuzane nezifo, kwaye akufuneki itshizwe. Ukuze kukhawuleziswe ukukhula, i-0.1% ukuya kwi-0.5% ye-potassium dihydrogen phosphate inokutshizwa kunye nokunkcenkceshela kwinqanaba lokugqibela.
