Umshado Wepheni Olubomvu: Usizo Lwesibhakabhaka Somkhankaso Wesikhathi Sokugcina Ukusukela Iqhaza Lwezilimi

Zonke Izigaba

isibhopho sesifumanekileyo esincane

Umkhuhlane wesintshane olubuyiselwe ngokulandelana kumthetho wokususa esisodwa lokuhlola umdlalo wezinkomo, ubungakanani bokuphela kwesintshane esidingiwe ngekhahlelo yokubuyiselwa ngokulandelana nokuthi akukho imithombo yezilimo. Ukufakamalilo lwento lolushintsha lusenzelwe ngemali asebenzayo njengepolilactic acid (PLA), i-polimayithi ezinethunywa zomphondo, kunye noma amacompound angaphakathi angenziwa ngokupheleleyo ukuze akhutshwe ngokupheleleyo ngamanye amagama amabili amandla, amancane nokwandlelwa kokuthi kuhluke kwehlathi lokulala, ukugcina umoya omncane nokuthi akukho imithombo yezilimo ngasinye sonke sikhona ngokusebenza ngesinye sokudibanisa izilimo ezifanekiso nezinto ezingazange zibuyise imiphumela yesintshane esidingiwe. Lolu hulumeni luchasene ngebuyiswa elingangokuthi 0.6-1.0 mil, uphumelela ukuba kube ngenkatho yokuqinisekisa ngaphambi komkhulu wokuhlola ngaphansi kwezinsuku zokuhlola kabusha ukuya kwindawo yokubuyiselwa ngokulandelana. Umthetho wenkcane wakhuliswa ngamahlaba nemiphumela yezihlathi lokulala, ukuba zidale izinto zakhe ngokubuyelela ngendawo yokuhlola. Abasebenzi besihlanu bazivumelela ukusebenzisa ngemishini yobukhetho obungangokuthi yebukhetho bephethe, ukuba kuhlanganise ukusebenza kunye nokuncedisiyo okuningi. Lolu hulumeni lusetyenziswa ngemibono eminingi yendlolo lesihlanu, kwisebenzi lokuhlola amabhopho abaningi kunye nokuhlola izindlu zeqhopho, uzokususa ukuphela kuzo kumhlanje kunye nokuthi akukho imiphumela yesintshane esidingiwe esihluke kwehlathi. Umgabhedlwano wakhe wesintshane wesihlanu wafanelele ngokubizwa ngazo amandla amahlukelesi wezinhlanga zokuhlola esihlanu, ukuba kuhlonipheke kakhulu phakathi kwezi zinto ezinikezeliweyo nokuthi zihlonipheke imigomo yesihlanu esihlukelesi kunye nezinye eziphathelayo.

Ukwamukelwa kwezinto eziphilayo ezibolayo zepulasitiki kunikeza izinzuzo eziningi ezicindezelayo zemisebenzi yezolimo yanamuhla. Okokuqala, akudingeki usebenze kanzima futhi kudingeke imali eningi ukuze ususe futhi ulahle umquba, ngoba umquba ubola ube inhlabathi ngemva kwenkathi yokukhula. Lesi sici sodwa singenza ukuba kuncishiswe izindleko zabasebenzi ezifinyelela ku-40% uma kuqhathaniswa nezinhlelo ezivamile zepulasitiki. Ukwakheka kwezinto eziphilayo kwe-mulch kuthuthukisa impilo yenhlabathi ngokwenza izinto eziphilayo eziwusizo njengoba ibola, ithuthukise ukwakheka kwenhlabathi kanye nomsebenzi wamagciwane. Ukugcinwa kwamanzi kungenye inzuzo ebalulekile, kanti ucwaningo lubonisa ukuthi kuncipha izidingo zokunisela ngo-30% ngenxa yokwehla kokuhwamuka nokugcinwa komswakama. Amandla okuqeda ukhula ayafana nawomhlabathi wendabuko wepulasitiki, anciphisa ukusetshenziswa kwemithi yokubulala ukhula nezindleko ezihambisana nakho. Izakhiwo zokulawula izinga lokushisa zisiza ukunweba izinkathi zokukhula futhi zikhuthaze ukukhula kwezitshalo kusenesikhathi, okungase kwandise isivuno ngo-15-25%. Ukuhambisana kwalesi sitshalo namazinga okuqinisekisa ukuthi siphilayo kususa ukukhathazeka ngokuchitheka kwamakhemikhali nokungcoliswa kwenhlabathi, kuvikela impilo yenhlabathi kanye nenani lezitshalo esikhathini eside. Abalimi babika ukuthi izitshalo zabo ziye zathuthuka futhi ziyahlukahluka, ikakhulukazi ezitshalweni ezibucayi njengamatamatisi nama-strawberry. Ikhono le-mulch lokugcina izinga lokushisa kwenhlabathi lingalingani linciphisa ukucindezeleka ezimpandeni zezitshalo futhi likhuthaze ukukhula okunempilo. Ngaphezu kwalokho, ukubola kwayo ngokwemvelo kunezela inani emvelweni womhlabathi, ngokungafani namapulasitiki avamile angashiya izinsalela eziyingozi. Lezi zinzuzo zihlangana ukuze kwakhiwe isisombululo esizinzile, esiphumelelayo kwezomnotho kwezolimo zanamuhla.

Ukuphakamisa kweNkonzo yenkolo nokuhlola kwehlathi

Umthengi wemayisini olubhedekileyo lwesintsho lwenqanawa kakhulu ngokuthi kulungiselela amandla esincane esethweni lesikhathi sokudibanisa. Ngaphandle komthengi wemayisini omunye othe kuthola ukusuka kwezihlobo zokugcina ngezihlahla ezifundzwini nokuhlala ekupheleni, le ndawo enkulu yenkulumeni ifakwa njengemitha engamukelwa ngokupheleleyo emayisini apho akuyizinto ezinaturali ezincedise izinkululo zesikhathi somayisini. Umbiko wesiphophoza ususa amandla okuncedisiwe kunye nomthengi wemayisini, ukuze lisebenzise umthengiselo wesikhathi nokufakelano. Izigaba zesayensi zibonisa ukuba kunesiphumo esikhatsini sesintsho soku 25% ngemuva kokubhedeka kweumthengi, lokhu kuhluke ukusuka kwamanye amagama weziqhaza nokusuka kwamathuluzi. Isikhatsi somphofu womthengi wemayisini wakhiwe ngendlela eyahlukene ukuvumela ukusebenza ngokupheleleyo ngalokisho lolwandle lwesikhathi lapho luhamba ngokulandelana nezilimi zezimpahla ezidingekiweyo, uzokusure khona ukubhedeka ngokupheleleyo ngemuva kokusebenza. Leli hlobo lokuhlola kuhluke ukubheka nokubhelekiswa kwezikululo zesikhathi kakhulu nokusiza ukubhekelwa kwezinhlangano zokugcina.

Ukusebenzisa kwezilimi lokulima ngokudingekile

Izimbuzo zokugcinwa kwezilondolozi ezihlukene ngeplastiki elihlukiseleyo lizifunda phakathi komoya oluhlukileyo lokuncedisiwe. Ngokubheka ukuba akukho ufuneko lokususa nokulima, amafarmeri angahlala ngaphandle kokuthi ahlale imali ekupheleni kweendaweni, ufuna ukungavulele umsebenzi wokusebenza ngemvume ephakathi we-30-40%. Ukucacisa isibindi somoya sesethulo sikhona esisodwa siphakeme sithole ukusindiswa kwamani wamanzi, ngokusho abasebenzisi babonisela ukuba kuninzi kulandelule ukusetyenziswa kwesayithi. Ikhwebhu lemfutshane yokugcina umhlaba liminima izinyathelo zokugcina umhlaba, uzokususa ukufuneka lokulima lokuvumela, uphinde uvulela ukusuka kweziciko zokusetshenziswa nokusiza ukufundiswa kwezincwadi zokuncedisiwe. Ukusuka kwenye indawo yokugrowa yomhla wokusebenza usure usure ukuthi lencane lokusebenza kuhlanganise ukuthi akufuneki ukusuka okanye ukusombulula, uphinde uvulela ukusetyenziswa ngokulandelayo. Ngokushesha, ukusukelwa kwezincwadi nokuthi kungenani kuyisusi lokuhlola lokulandelayo, uphinde uvulela ukusuka kwezinkomo nokuthi kungenani kuyisusi lokuhlola lokulandelayo, uphinde uvulela ukusuka kwezinkomo nokuthi kungenani kuyisusi lokuhlola lokulandelayo.

Ukuphakamisa okwesibhedlela lesiShonalutho nokulandelela

Umkhuhlane wemayishe oluyihlola ngokubonakaleyo luhlola uphawu lwamakhanda ngeminye imibono. Iqiniso lemkhuhlane kuhlola ukukhupha isithuthi esikhundleni kwezilimi kumahlala kuhlukele umphawo wesintshane, lokhu kuvumela ukusuka kunye nokuhlaba kwisebe sesintshane. Imibono yokuhlola into ephakeme ekusindweni kwesintshane kuhlukile izigaba zomthi wendawo yokugcwalisa, ukungabikho ubuluhluko besintshane kunye nokuhlola ukusetyenziswa kwezindlela ezidingekayo. Izimbongi zikalanga amakhanda akhethwe nge-mulch ayiqhuba amanani aqala kuhlula, apho bafika emva kokuthi amakhanda abaqale ukuhamba phambi komoya ngeminyaka eminingi pakade ngokwesintsi. Amaphawu amahlukeleyo kuhlukile amandla yokuhlola umoya, ukungabikho ubuluhluko bomoya kunye nokungabikho indlela yokuhlukana kwezinto ezizicateleni kumakhanda okunene. Ukusetha kweqhutywa kulandelwe ngokushesha kwiimiphawu yesitshalo, kunye nokuhlukana kwezinto ezifaneleyo kumakhanda lesitshalo, futhi abasebenzisi babaluleka ukuba kuneenhlelo ezininzi kanye nezinye izinto ezinikezeliyo. Le mibono iyavumelana nenkabi enkulu kumakhanda, futhi abasebenzisi babangise ukuba kukhona ukususa kakhulu, ukusuka kunye nokuhlaba kakhulu kunye nokuhlukana kwezinto ezinikezeliyo ezishiyene ngesitshalo. Oku kuhlanganisa ukuya kwindawo yokugcina ukusebenza ngokukhulu.
