Yimiphi imisebenzi yezemvelo yomhlaba ongavamile ezitshalweni?

 

umhlaba ongavamile

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.
