Enkathini yezinhlelo zokunisela zobuchwepheshe obuphezulu kanye namadivayisi ahlakaniphile okulima, ithuluzi elilodwa lasendulo liyabuya buthule: imbiza yobumba i-olla. Isekelwe emasikweni okulima akudala amakhulu eminyaka, i-olla - imbiza yobumba elula, enezimbobo egqitshwe enhlabathini - inikeza ikhambi elihle nelonga amanzi kubalimi, abalimi bezitshalo, kanye nabathandi bezitshalo abaqaphela imvelo. Nakuba zingase zibonakale zingelutho ekuqaleni, izimbiza zobumba i-olla zinomlando othakazelisayo futhi zithola indawo evelele kakhulu ezingadini zanamuhla emhlabeni jikelele.
Ukubuka Umlando
Imvelaphi yembiza yobumba ibuyela emuva ezinkulungwaneni zeminyaka. Abalimi bathole ukuthi ukumboza ingxenye yesitsha sobumba esinezimbobo enhlabathini kungaletha amanzi ngqo ezimpandeni zezitshalo ngokwemvelo. Le ndlela yanciphisa kakhulu imfucuza yamanzi ebangelwa ukuhwamuka noma ukugeleza kwamanzi futhi yakhuthaza ukukhula kwezitshalo okunempilo. Ngokungafani nezindlela zokunisela ezivamile, ukukhishwa kancane kwe-olla kudala izinga lomswakama elihlala njalo izitshalo ezikhula kulo - okwenza kube ngcono kakhulu ezindaweni ezomile noma phakathi nezinyanga zasehlobo.
Namuhla, izimbiza zobumba aziwona nje amathuluzi awusizo — ziyizimpawu zokulima okusimeme kanye nokulima okucabangayo.
Indlela Izimbiza Zobumba Ezisebenza Ngayo
Umlingo webhodwe lobumba ulele ezintweni zalo. Lenziwe ngobumba olunezimbobo, ibhodwe livumela amanzi ukuthi angene kancane kancane ezindongeni zalo, angene ngqo enhlabathini ezungezile. Njengoba inhlabathi yoma, ngokwemvelo idonsa umswakama ebhodweni, idale uhlelo lokunisela oluzilawulayo. Lokhu kusho ukuthi izitshalo zithola amanzi kuphela uma ziwadinga, okunciphisa kokubili ukunisela ngokweqile kanye nokucwila ngaphansi kwamanzi.
Ziza ngobukhulu obuhlukahlukene, kusukela ezitsheni ezincane zezitshalo ngazinye kuya ezitsheni ezinkulu ezifanele imibhede yemifino noma izingadi zezimbali.
Kungani Abalimi Bemukela Izimbiza Zika-Olla Namuhla
Eminyakeni yamuva nje, izimbiza zobumba ze-olla ziphinde zathandwa, ngenxa yezindlela eziningana ezibalulekile:
1. Ukusimama: Njengoba ulwazi olukhulayo ngokulondolozwa kwamanzi lukhula, abalimi bafuna izindlela zokunciphisa imfucuza. Uhlelo lokunisela olukhipha kancane lwe-olla lungonga amanzi afinyelela ku-70% uma kuqhathaniswa nezindlela zokunisela zendabuko.
2. Ukunethezeka: Abalimi abamatasa bathanda indlela i-olla enganakekeli kahle ngayo. Uma isigcwele, inisela izitshalo ngokwayo izinsuku noma amasonto.
3. Impilo Yezitshalo: Ngenxa yokuthi amanzi alethwa ngqo ezimpandeni, izitshalo zakha izimpande eziqinile futhi azithinteki kakhulu ezifweni zesikhunta ezibangelwa amaqabunga anamanzi.
4. Ukutshala Ingadi Okungangcolisi Imvelo: Izimbiza ze-Olla zenziwe ngobumba bemvelo, ezingenazo ipulasitiki noma amakhemikhali ayingozi, ezihambisana nemikhuba yokutshala engangcolisi imvelo.
Okungaphezu Kwethuluzi Nje
Ngaphandle kwezinzuzo zazo ezingokoqobo, izimbiza ze-clay olla zinikeza ukukhanga kanye nobuhle basemaphandleni. Abalimi abaningi bazifaka ezindlini zokuhlobisa, behlanganisa umsebenzi nokukhanga kobuhle. Kusukela ezingadini zemifino kanye nemibhede yezimbali kuya ezitshalweni ze-patio kanye nezimbiza zangaphakathi, i-olla ihlangana kahle nezitayela ezahlukene zengadi, idala ubuhle kanye nokusetshenziswa.
Abanye abalimi abasha sebeqalile nokwenza ngokwezifiso izimbiza zabo ze-olla ukuze zinike izipho noma amaphrojekthi akhethekile - engeza imibala, imiklamo, noma ukuthinta okwenziwe ngokwezifiso ukuze kwenziwe imbiza ngayinye ibe ngeyahlukile. Lo mkhuba wokwenza ngokwezifiso ubonisa intshisekelo ekhulayo yezesekeli zengadi eziyingqayizivele, ezenziwe ngezandla, okuvumela abalimi ukuthi baveze ubuhlakani ngenkathi behlala besebenza.
Ukukhanga Okungapheli Kwengadi Yobumba
Izimbiza ze-olla ezilula kodwa ezisebenzayo, ezisixhumanisa nokuhlakanipha kwasendulo kokutshala ingadi, zisekela izitshalo ezinempilo, futhi zikhuthaza ukusimama. Kungakhathaliseki ukuthi ungumlimi osaqalayo noma onolwazi, ukusebenzisa imbiza ye-olla kuletha ukusebenza, ubuhle, kanye nokuphila kunoma iyiphi ingadi.
