Isigaba Izakhiwo

Namuhla, cishe zonke izakhiwo zomhlaba wangasese, ungabona idivayisi ejwayelekile futhi ejwayelekile, njenge-greenhouse, ehloselwe ukutshala izitshalo ezihlukahlukene zezitshalo. Zijwayele ukusetshenziselwa ukutshala imifino, kodwa zivame ukutshala amajikijolo nezimbali kuzo.

Wonke umuntu othanda ukulima epulazini ufuna ukukhulisa inani eligcwele lemifino yezitshalo kulesi sakhiwo. Kodwa akulona njalo ubukhulu bendawo yomhlaba okukuvumela ukuba ufeze umphumela oyifunayo. Ezimweni ezinjalo, ukushisa okwakhiwa phezu kwendlu yangasese noma ngisho nokushisa okuphezu kwendlu yegalaji kungaba yisixazululo esibalulekile.

Ihousehouse yokushisa ingenye yezakhi zenani elikhulu leziqephu zomuntu siqu. Izakhiwo ezinjalo zingase zihluke komunye nomunye ngemigomo, isimo, izinto ezisetshenziselwa ukugqoka. Enye yezinhlobonhlobo zezakhiwo zokushisa okushisa yi-greenhouse emhubheni. Inenzuzo eningana futhi ingasetshenziswa kokubili efudumele nangenkathi ebandayo.

Uhlaka lwama-polycarbonate lokushisa lokushisa luhlale lubhekene nokucindezeleka okukhulu kwezemvelo. Umoya neqhwa uma kwenzeka ukuthi isakhiwo singagcizelelwanga yizintambo ezengeziwe, kungaholela emiphumeleni engafanele, okungukuthi: ukubhubhisa noma ukubhubhisa ngokuphelele isakhiwo. Isikhathi sasebusika sibucayi ikakhulukazi, lapho inani elikhulu leqhwa liqoqa phezulu.

Isidingo sokwakha ukushisa okubamba ukushisa kwakudingeka sibhekane cishe naso sonke isivini. Indima ebalulekile idlalwe ngokukhetha izinto zokuhlala; namuhla, ifilimu yeplastiki ye-greenhouse, ingilazi, i-polycarbonate yamaselula, nama-agrofiber asetshenziselwa kakhulu lokhu, zonke lezi zindlela zinezinzuzo nezinzuzo zazo.

Sonke siyazi ukuthi ukushisa okushisa emkhakheni wensimu kuyadingeka ekukhuleni izitshalo ezihlukahlukene zokushisa. Ngakho-ke, ukunakekelwa kahle kuye, hhayi nje entwasahlobo, lapho silungiselela ukutshala ngenkathi entsha, kodwa ebusika, futhi ngokujwayelekile unyaka wonke, umzuzu obaluleke kakhulu. Kulesi sihloko sizokhuluma ngokuningiliziwe mayelana nendlela yokunakekela i-greenhouse ebusika, ukuthi ungayilungisa kanjani entwasahlobo isikhathi esizayo nokuthi yini okudingeka yenziwe ngenhlabathi ngaphakathi kwayo.

Ukwakhiwa kanye nendawo yendawo yokushisa ebusweni akuyona umsebenzi wokugcina wokulungiselela imifino kuwo. Ukuze usebenze kalula nendawo efanele ngaphakathi kwesakhiwo sesitshalo, udinga ukuyilungisa kahle futhi uyihlomise kahle. Izinhlobo zokugcina izithombo ngokohlobo lwangaphakathi lwamalungiselelo okugcina izithombo ngendlela yokutshala imifino kuzo zihlukaniswe ngamaqembu athile: Ground.

Ubusika buya ekupheleni, uMashi usondela - isikhathi sokuqala izindaba zegadi nezingadi. Ngalesi sikhathi, wabeka isisekelo sokuvuna esikhathini esizayo, futhi kanye nayo ingcebo etafuleni lakho lonke unyaka ozayo. Abalimi abaningi babheke phambili ngalesi sikhathi, bakhathazekile emibhede nasemhlabathini. NgoFebhuwari - Mashi - lokhu kungukuqala kokuhlwanyela izithombo, ngakho-ke kunakekela ukukhula okuqinile okunempilo.

I-Polycarbonate greenhouse isakhiwo esiqinile esingasetshenziswa ukuhlala izakhamuzi zasehlobo ukuze zikhule izitshalo ezithisa ukushisa isikhathi esingaphezu kwesisodwa. Kodwa, ukuze uyigcine esimweni sokusebenza futhi ukhule ngokuphumelelayo imifino kuwo, ukushisa okudingayo kudinga ukunakekelwa ngezikhathi ezahlukene zonyaka. Kulesi sihloko sizokutshela indlela yokulungisa i-greenhouse ekwindla ukuze kuphumelele ubusika, futhi ukhulume ngalokho okudingeka kwenziwe entwasahlobo, ngaphambi kokuqala kwenkathi.

Ukulima ukukhiqiza abamba ukushisa kuyithuba elihle lokuba namajikijolo nemifino etafuleni cishe pheze unyaka wonke. Futhi kuyisiqinisekiso sokudla imikhiqizo ehlanzekile engokwemvelo ngaphandle kwe-nitrate eyingozi, ukungcola okungaqondakali okuhlukahlukene kanye nama-hormone okukhula. Izinzuzo zokukhula ezindlini zokugcina izithombo zingabhalwa ngezikhathi zonke: ukuvuna kokuqala entwasahlobo, ikhono lokutshala izinhlobo ezingavamile zezitshalo nezimbali ezingahlali emhlabathini ovulekile ngenxa yezimo ezingavumelekile zezulu.

Ukuthenga noma ukungathengi i-greenhouse ngumbuzo wokuqala abanikazi abajabulayo bamahektare abalulekile abazibuza. Futhi iningi lazo liphendula kahle: akungabazeki ngesidingo salesi sakhiwo. Futhi lapha abalimi babhekene nenkinga entsha. Yeka kanjani ukuthi ungalahlekelwa ngobuningi bamamodeli, izakhiwo kanye nezinto ezakhiwa yizimboni zanamuhla?

Ukushisa kulesi sakhiwo kukhulisa kakhulu amathuba okulimaza. Kodwa akuhlali ngaso sonke isikhathi kukhishwa isikhala samahhala kuso. Ngakho-ke, ngokuvamile ukushisa okuluhlaza okwakudonga kutholakala ngqo odongeni lendlu. Ukwakhiwa okunjalo akulondolozi isikhala kuphela, kodwa futhi isikhathi, ngoba kudinga isikhathi esincane kakhulu sokudalwa nokugcinwa kwayo kunokuba kube khona ukushisa okwehlukile.

Inhlangano esakhiweni sombhede ofudumele ungenye yezindlela eziphumelelayo zokuqhathanisa isikhathi sokutshala kwezithombo zemifino ku-greenhouse. Ekuqaleni kwezinsuku zokushisa zokuqala, umoya uvuselela ngokushesha, kodwa imisebe yelanga elithakathaka elithakazelanga ilanga alanele ukufudumala inhlabathi. Ukuhlelwa kwemibhede efudumele ebamba lokushisa kuzosiza ukusheshisa inqubo.

Isidingo sokwakha ukushisa okubamba ukushisa kwakudingeka sibhekane cishe naso sonke isivini. Inendima ebalulekile idlalwe ngokukhetha izinto zokukhosela; namuhla, ifilimu ye-polyethylene, ingilazi, i-polycarbonate, i-agrofibre isetshenziselwa kakhulu lokhu, zonke lezi zindlela zinezinzuzo nezinzuzo zazo.

Ama-polymers yizinto ezisetshenziswa kabanzi ezimbonini eziningi. Zichitha izingxenye zokhuni, zensimbi nezingilazi. Namuhla, ama-polymers atholakale ezindaweni ezidakayo kanye namazwe omabhizinisi asezimboni. Amaplastiki alula, akhululekile ukusebenza nawo. Abesabi ukhunta nemifucumfucu, abonakaliswa yi-chemistry caustic.

Izithombo zokugcina izithombo zadalwa umuntu ukuze ukwazi ukuhlakulela izitshalo ezitshalwe, kungakhathaliseki ukuthi unyaka wingaphandle kwewindi. Enye yezindaba ezibaluleke kakhulu ezihlobene nokulima kwenhlabathi ngemuva kweglasi lokubamba ukushisa yi "Indlela yokuqinisekisa i-microclimate enhle ebamba lokushisa elingase lisekele ukukhula nenhlalakahle yezitshalo ngisho naseqhwa eliqine kakhulu?
