Ucwaningo ngemiphumela yeizakhi zomhlaba ezingavamile on Ukwakheka kwezitshalo kubonise ukuthi izakhi zomhlaba ezingavamile zingakhuphula okuqukethwe kwe-chlorophyll kanye nesilinganiso se-photosynthetic ezitshalweni;Khuthaza ngokuphawulekayo ukuhluma kwezitshalo futhi usheshise ukukhula kwezimpande;Qinisa umsebenzi wokumuncwa kwe-ion kanye nokusebenza komzimba kwezimpande, futhi kuthinte umsebenzi wokulungiswa kwe-nitrogen yezitshalo nama-enzyme athile;Kwatholakala ngokulandela umkhondo we-athomu ukuthi izakhi zomhlaba ezingavamile zingakhuthaza ukumuncwa nokuthuthwa kwe-nitrogen, i-phosphorus, ne-potassium ngezitshalo.Izakhi zomhlaba ezingavamile zingakhuthaza ukukhula nokukhula kwezitshalo, futhi zibe nomthelela omuhle ekuvunweni kwezitshalo.
Izakhi zomhlaba ezingavamilezibe nomthelela omkhulu ekukhuleni kwembewu yezitshalo.Ukugxila okufanele kwesisombululo somhlaba esingavamile ukukhuthaza ukuhluma kwembewu ngu-0.02-0.2 amagremu ngekhilogremu (amakhilogremu angu-2).Izakhi zomhlaba ezingavamile zingaphinde zikhuthaze ukukhula kwezitshalo, zikhuthaze ukwanda kwesisindo esisha sezitshalo kanye nezimpande zesisindo esisha, futhi zibe nomthelela omkhulu oshukumisayo ekukhuleni kukakolweni, irayisi, ummbila, kanye nemifino ekugxilweni okusuka ku-5 kuya ku-100 ppm.Ezimweni ezifanele, ziba nomthelela ekukhuleni kwezimpande zezitshalo, iziqu, namaqabunga, okusobala kakhulu ukwanda kwendawo yamaqabunga.Izakhi zomhlaba ezingavamile zinomthelela okhethekile ekuhlumeni kwezitshalo nasekukhuleni kwezimpande, futhi ukugxila okuphelele kokuphromotha ku-0.1-1ppm.Ngaphezu kwalokhu kugxilwa, ukuvinjelwa kwenzeka.Umhlaba ongavamile ukhuthaza ukukhula kwezimpande ngokuyinhloko ngokukhuthaza ukuvela kwezimpande ezizayo, okuthinta ukuhlukaniswa kwamaseli kanye nezimpande ze-morphogenesis.Ukwengeza izakhi zomhlaba ezingavamile endaweni yokukhula kwezimpande kungakhuthaza ukumuncwa kwe-phosphorus ngohlelo lwezimpande.Ukugxila okuphelele kokumuncwa kwezimpande kwe-phosphorus kungu-0.1~1.Oppm;Kungaphinde kukhuthaze ukumuncwa kwe-nitrogen ne-potassium.Izakhi zomhlaba ezingavamile zingathuthukisa umsebenzi we-physiological wezimpande, obonakaliswa ngokuvuselela ukuthungwa kwe-root sap kanye nokuthuthukisa umsebenzi we-enzyme ezimpandeni.Izakhi zomhlaba ezingavamile zihlobene eduze ne-photosynthesis yezitshalo futhi zingakhuthaza ukulungiswa kwezitshalo kwe-carbon dioxide photosynthesis, ngaleyo ndlela kuthuthukiswe ukusebenza kahle kwe-photosynthesis.Ukuhlola kwabonisa ukuthi inani eliphelele le-chlorophyll emaqabunga ezitshalo eziphathwe umhlaba ongavamile liyenyuka, ikakhulukazi inani le-chlorophyll A, okubangele ukwanda kwesilinganiso se-chlorophyll A/B.
Ngaphezu kwalokho, ukufafaza kwe-foliar kwezakhi zomhlaba ezingavamile kungase futhi kwandise umsebenzi we-nitrate reductase ezitshalweni, kunciphisa kakhulu okuqukethwe kwe-nitrate nitrogen emzimbeni.Umthelela wezakhi zomhlaba ezingavamile ekulungisweni kwe-nitrogen okunikezwa amaqhuqhuva kabhontshisi wesoya ubonakaliswa ekwandiseni inani lamaqhuqhuva kanye nomsebenzi wokulungisa i-nitrogen.Izakhi zomhlaba ezingavamile zingase futhi zithuthukise ikhono lokulawula le-cytoplasmic nuclei ekuvuzeni kwe-electrolyte, ngaleyo ndlela kuthuthukiswe ukumelana kwesitshalo esomiso, usawoti, kanye ne-alkali.
