Kwiintsuku zamva nje, imozulu yenkungu eqhubekayo ayizange ibangele ingozi kwimpilo kuphela, kodwa inefuthe elibi ekukhuleni nasekuphuhliseni imifuno kwi-greenhouse yefilimu ebusika.Ebusika, njengenqanaba eliphambili lokuvelisa imifuno kwii-greenhouses ezincinci zefilimu, kubaluleke kakhulu ukulawula imifuno kakuhle kwimozulu yenkungu.
Imozulu yenkungu ephindaphindiweyo ebusika iya kukhokelela ngokuthe ngqo ekunqongopheni kwelanga kunye nokufuma okuphezulu kwi-greenhouse, okuya kuchaphazela kakhulu ukugcinwa kobushushu kunye nokukwazi ukugcinwa kobushushu be-greenhouse yelanga.Ilishwa lokukhula kwemifuno.Okwesibini, ukufuma komoya ophezulu kuya kwandisa iziganeko zemifuno.Ndingenza ntoni?Yintoni ekufuneka uyinikele ingqalelo?
Imozulu yenkungu kufuneka ifakwe umoya kancinane kangangoko kwaye ikhulise ukukhanya: Kukho esinye isiphumo esingahoywayo sithi-kukho izinto ezingcolisa umoya ezingakumbi kwimozulu yenkungu.Nangona ezi zinto zingcolisayo zincinci kakhulu, ziyakuvimba i-stomata xa ziwela emagqabini.Ukuchaphazela ukuphefumla kwamagqabi emifuno, ukuvimba ukungena kwe-carbon dioxide, kwaye emva koko kuchaphazela ukukhula kwemifuno.Xa udibana nemozulu ye-haze, ixesha lokungena kwemifuno kwi-greenhouses kufuneka lifaneleke, kwaye uzame ukukhetha ukungafaki umoya ngosuku.
Ixesha lokungenisa umoya kwi-greenhouse kufuneka lihlengahlengiswe ukusuka kwintsimbi yesi-8 kusasa ukuya malunga nentsimbi yesi-2 emini kwangolo suku (eli xesha linempembelelo efihlakeleyo yenkungu).Ukongeza kwimbuyekezo efike ngexesha loxinzelelo lwekharbon diokside kwi-greenhouse, iphinda incede ukukhula kwezityalo kunye nokuthintela ukungcoliseka komoya.Izinto ezingcolileyo ziwela emagqabini.Ngethuba leentsuku zenkungu, ngokude nje kungekho khephu kwimozulu, i-greenhouse thermal insulation inokuvulwa kwangethuba kusasa.
Ukugquma emva kwemini ukwenza isityalo sifunxe ukukhanya okuthe saa.Akukhuthazwa ukuba ungavezi i-quilt ngaphezu kweentsuku ezi-3 ezilandelelanayo.Inokufaneleka ukuhlawulela ukukhanya kunye nokuthintela izifo kwimifuno ye-greenhouse kwinkungu kunye neentsuku ezinqabileyo.Abalimi banokukhetha ukucoca ifilimu kwindawo enelanga ukwandisa ukuhanjiswa kokukhanya kwefilimu.Ngexesha elifanayo, ukucoca ngexesha elifanelekileyo amaqabunga amadala kunye namaqabunga agulayo kwizityalo kwi-shed ukunyusa ukukhanya okuhlakazekileyo phakathi kwezityalo.
