Kuenderera mberi kwekutarisa kwechirimwa "kushushikana kwemvura" kunonyanya kukosha munzvimbo dzakaoma uye zvagara zvichiitwa nekuyera hunyoro hwevhu kana kugadzira evapotranspiration modhi kuti uverenge huwandu hwekunyungudika kwepasi uye kubuda kwechirimwa.Asi pane mukana wekuvandudza kushanda kwemvura kuburikidza nehunyanzvi hutsva hunonyatsonzwa kana zvirimwa zvinoda kudiridzwa.
Vatsvakurudzi vakasarudza mashizha matanhatu akaiswa zvakananga kune chiedza chechiedza uye akaisa ma sensors emashizha paari, kudzivisa tsinga huru nemicheto.Vainyora zviyero pamaminetsi mashanu oga oga.
Tsvagiridzo iyi inogona kutungamira mukugadzirwa kwehurongwa hwekuti mashizha pinch sensors anotumira ruzivo rwemwando rwechirimwa kune imwe nzvimbo yepakati mumunda, iyo inozotaurirana munguva chaiyo neyekudiridza kune zvirimwa zvemvura.
Shanduko dzezuva nezuva mukukora kweshizha dzaive diki uye hapana shanduko yakakosha yezuva nezuva yaionekwa sezvo hunyoro hwevhu hwaifamba kubva kumusoro kusvika pakusvava.Zvakadaro, kana hunyoro hwevhu hwaive pazasi pekusvava, kushanduka kwekukora kweshizha kwainyanya kuoneka kusvika ukobvu hwemashizha hwadzikama mukati memazuva maviri ekupedzisira ekuedza apo mwando wakasvika pa5%. Capacitance, iyo inoyera kukwanisa kweshizha kuchengeta chaji, inoramba yakangofanana panguva yerima uye inowedzera nekukurumidza munguva yechiedza.Izvi zvinoreva kuti simba chiratidzo chephotosynthetic chiitiko.Kana hunyoro hwevhu huri pazasi peiyo wilting point, iyo diurnal shanduko mukugona inoderera uye inomira zvachose kana volumetric ivhu hunyoro hunowira pasi pe11%, zvichiratidza kuti mhedzisiro yekushushikana kwemvura pane simba inocherechedzwa kuburikidza nemhedzisiro yayo paphotosynthesis.
“Ukobvu hwepepa hwakafanana nebharumu-inowedzera nekuda kwe hydration uye zvibvumirano nekuda kwekunetseka kwemvura kana kupera simba,”Zvichitaurwa zviri nyore, huwandu hwemashizha hunochinja nekuchinja kwemamiriro emvura yechirimwa uye nemwenje wepakati.Nokudaro, kuongororwa kwemashizha emashizha uye kuchinja kwehutano kunogona kuratidza mamiriro emvura mumiti - tsime rekumanikidza.»
