Ukuhlolwa rhoqo “koxinzelelo lwamanzi” kwezityalo kubaluleke kakhulu kwiindawo ezomileyo kwaye ngokwesithethe bekuphunyezwa ngokulinganisa ukufuma komhlaba okanye ukuphuhlisa imifuziselo ye-evapotranspiration ukubala isimbuku sokuphuphuma komphezulu womhlaba kunye nokuphuma kwezityalo.Kodwa kukho amandla okuphucula ukusebenza kakuhle kwamanzi ngokusebenzisa itekhnoloji entsha eziva ngokuchanekileyo xa izityalo zifuna ukunkcenkceshelwa.
Abaphandi bakhetha ngokungaqhelekanga amaqabunga amathandathu abonakaliswe ngokuthe ngqo kumthombo wokukhanya kwaye afake izinzwa zeqabunga kubo, ukuphepha imithambo ephambili kunye nemiphetho.Babhala imilinganiselo rhoqo ngemizuzu emihlanu.
Olu phando lunokukhokelela kuphuhliso lwenkqubo apho izivamvo zokuncitshiswa kwegqabi zithumela ulwazi oluchanekileyo lokunyakama kwezityalo kwiyunithi esembindini yentsimi, ethi ke inxibelelane ngexesha lokwenyani kunye nenkqubo yokunkcenkceshela kwizityalo zamanzi.
Utshintsho lwemihla ngemihla kubukhulu bamagqabi beluncinci kwaye akukho tshintsho lubalulekileyo lwemihla ngemihla oluphawulweyo njengoko amaqondo okufuma komhlaba ebesuka phezulu ukuya kwindawo yokubuna.Nangona kunjalo, xa ukufuma komhlaba kungaphantsi kwendawo yokubuna, ukuguquka kobungqingqwa bamagqabi kwabonakala ngakumbi de ubungqimba bamagqabi buzinzile ngeentsuku ezimbini zokugqibela zovavanyo xa ukufuma kufikelele kwi-5%. Ubukhulu, obulinganisa ukukwazi kwegqabi ukugcina intlawulo, buhlala bufana nobuncinci ngexesha lobumnyama kwaye bunyuka ngokukhawuleza ngexesha lokukhanya.Oku kuthetha ukuba umthamo yimbonakaliso yemisebenzi yephotosynthetic.Xa ukufuma komhlaba kungaphantsi kwendawo yokubuna, utshintsho lwe-diurnal kumthamo luyancipha kwaye luyeke ngokupheleleyo xa ukufuma komhlaba we-volumetric kuwela ngaphantsi kwe-11%, ebonisa ukuba umphumo woxinzelelo lwamanzi kumthamo ubonwa ngempembelelo yayo kwi-photosynthesis.
“Ubukhulu bephepha bufana nebhaluni-iyanda ngenxa ye-hydration kunye nezivumelwano ngenxa yoxinzelelo lwamanzi okanye ukuphelelwa ngamanzi emzimbeni,”Ngamafutshane, umthamo wegqabi uyatshintsha ngotshintsho kwisimo samanzi sesityalo kunye nokukhanya okungqongileyo.Ngaloo ndlela, ukuhlalutya kobunzima bamagqabi kunye nokutshintsha kwamandla kunokubonisa imeko yamanzi kwisityalo - ingcinezelo yoxinzelelo.»
