Cwaninga ngemiphumela yeizinto zomhlaba ezingavamile oI-N Plant Physiology ikhombisa ukuthi izinto zomhlaba ezingavamile zingakhulisa okuqukethwe kwe-chlorophyll kanye nezinga le-photosynththetic ezitshalweni; Ukukhuthaza kakhulu izimbangela zezitshalo nokusheshisa ukukhula kwezimpande; Qinisa umsebenzi wokutholwa kwe-Ion kanye nomsebenzi wokusebenza kwezimpande, futhi uthinte umsebenzi wokulungiswa kwezitshalo ze-nitrogen nama-enzyme athile; Kwatholakala ngokulandela ama-athomu alandelwa ukuthi izinto zomhlaba ezingavamile zingakhuthaza ukumuncwa nokuhamba kwe-nitrogen, phosphorus kanye ne-potassium ngezitshalo. Izinto zomhlaba ezingavamile zingakhuthaza ukukhula kwezitshalo nentuthuko, futhi zibe nomphumela omuhle ngesivuno sezilimo.
Izinto zomhlaba ezingavamileIba nomphumela obalulekile wokukhuthaza kwisitshalo imbewu yokuhluma. Isixazululo esifanelekile sekhambi lomhlaba elingavamile ukukhuthaza ukuhluma kwembewu kungu-0,02-0.2 amagremu ngekhilogremu (amakhilogremu ama-2). Izinto zomhlaba ezingavamile futhi zingakhuthaza ukukhula kwezitshalo, zigqugquzele ukwanda kwesisindo esisha nesisindo esisha, futhi kube nomthelela omkhulu ekukhuleni kukakolweni, ilayisi, ummbila kanye nezingubo zokugxila kusuka ku-5 kuye ku-100 ppm. Ekugxileni okufanele, banomthelela ekukhuleni kwezimpande zezitshalo, iziqu, namaqabunga, ngokusobala okusobala kakhulu ukwanda endaweni yamaqabunga. Izinto zomhlaba ezingavamile zinomthelela okhethekile ekukhuleni kwezimpande nokukhula kwezimpande, kanye nokuhlushwa okulungile ekuthuthukiseni izimpande kungu-0,1-1ppm. Ngaphezulu kwalokhu okuhlushwa, kwenzeka invibition. Umhlaba ongavamile ukhuthaza ukukhula kwezimpande ikakhulukazi ngokuqhakambisa ukwenzeka kwempande evelayo, okuthinta umehluko weseli kanye nezimpande morphogenesis. Ukungeza izinto zomhlaba ezingandile ezindabeni zokukhula kwezimpande kungakhuthaza ukumuncwa kwe-phosphorus ngohlelo lwezimpande. Ukuhlushwa okuhle kokutholwa kwezimpande kwe-phosphorus yi-0,1 ~ 1. Oppm; Kungagqugquzela futhi ukumuncwa kwe-nitrogen ne-potassium. Izinto zomhlaba ezingandile zingathuthukisa umsebenzi womzimba wezimpande, eziboniswe ngokuvuselela ukukhishwa kwezimpande zempande nokuthuthukisa umsebenzi we-enzyme ezimpandeni. Izinto zomhlaba ezingandile zihlobene kakhulu nesitshalo sezithombe ze-Photoynthesis futhi zingathuthukisa ukulungiswa kwezitshalo ze-carbon dioxide photosynthesis, ngaleyo ndlela kuthuthukise ukusebenza kahle kwe-photosynthesis. Isivivinyo sikhombise ukuthi inani eliphelele le-chlorophyll emaqabungeni ezitshalo aphathwa ngomhlaba elingavamile lenyuke, ikakhulukazi inani le-chlorophyll a, eliphumela ekukhuphukeni kwe-chlorophyll a / b ratio.
Ngaphezu kwalokho, ukufafaza kwe-foliar kwezinto zomhlaba ezingavamile nakho kungakhulisa umsebenzi we-nitrate red izitshalo ezitshalweni, kunciphisa kakhulu okuqukethwe kweNitrate Nitrogen emzimbeni. Umphumela wezinto zomhlaba ezingandile ohlelweni lwe-nitrogen olunikezwe amaqhubu e-soya abonakaliswa ekwandiseni inani lama-nodule kanye nomsebenzi wokulungiswa kwe-nitrogen. Izinto zomhlaba ezingavamile nazo zingathuthukisa amandla okulawula we-cytoplasmic nuclei ukuze aclectorlyte ukuvuza, ngaleyo ndlela athuthukise ukumelana kwesitshalo kwisomiso, usawoti, kanye ne-alkali.
