Nri micronutrint - nri fatịlaịza

I. ụdị fatịlaịza Zinc

Fatịlaịza Zince bụ ihe na-enye zinc dị ka ihe na-edozi osisi. A na-ejikarị Zinc fatịlaịza na ahịa gụnyere zinc sulfate, zinc chloride, zingụ carbonate, zincomate mara mma, na zinc oxide. N'ime ndị a, Zinc sulfate Hanthahydrate (ZNDO4O, nwere ihe dị ka 23% zn) na zinc chloride (znc2, nwere ihe dị ka 47.5% z7) na-ejikarị. Ihe ndị a bụ ihe ndị dị ọcha na-acha ọcha na mmiri, ma na-elekọta ga-egbochi nnu nnu site na iji ya na-edobe ya n'oge ngwa.

II. Usoro na ọrụ nke fatịlaịza Zinc
Zinc bụ otu n'ime ihe dị mkpa micronutrients maka osisi, na-edekọ n'ụdị nke ihe ọ cation Zn2 ​​+. Ihe mmeghari nke zinc n'ime osisi bu uzo adighi agbanwe. Zinc na-emetụta njikọ nke homonụ na ihe ọkụkụ; Mgbe Zinc dị ụkọ, ọdịnaya nke homonụ na-eto na buds na-ebelata, na-ebute uto iji na-eleda anya na osisi dị mkpụmkpụ. Ọzọkwa, ziinc na-arụ ọrụ dị ka onye na-eme ihe maka ọtụtụ enzymes, na-enwe mmetụta buru ibu na carbon na nitrogen metabolism na osisi, wee si otú ahụ na-eme nhọrọ photosy. Zinc na-eme ka osisi 'guzogide nrụgide, na-abawanye ọka ọka, ma na-agbanwe oke mkpụrụ ka ị ga.

III. Ngwa nke fatịlaịza fatịlaịza
Mgbe ọdịnaya zinc dị irè n'ala dị n'etiti 0,5 mg / n'arọ na 1.0 mg / kg, ị na-etinye fatịlaịza Zinc nwere ike ịbawanye mkpụrụ ma melite ogo mkpụrụ osisi. Usoro ntinye akwụkwọ maka fatịlaịza fatịlaịza gụnyere iji ha dị ka nri fatịlaịza, topsdresssing, na mkpụrụ nri mkpụrụ. A na-ejikarị fatịlaịza na-egbu egbu dị ka fatịlaịza basal, yana ntinye akwụkwọ nke 1-2 n'arọ nke zinc sulre, nke nwere ike ịgwakọta ya na physiligicallyrs fatịlaịza. Maka ubi nwere mkpụmkpụ fọnc dị nro, nwetaghachi akwụkwọ ga-eme ga-eme n'afọ 1-2 kwa; Maka mpaghara ezughi oke, enwere ike belata ngwa ma duzie kwa afọ ma ọ bụ n'afọ ọzọ. Dịka precdresssing, a na-ejikarị fatịlaịza Zinc dị ka ọkọlọtọ nke 0.02% nke mkpụrụ osisi 0.1% -0.5% maka ọka na osikapa. A ga-efesa osikapa 0.2% zinc sulfate na tillering, booting, na okooko osisi; Enwere ike fesaa ya na 5% zin silfate otu ọnwa tupu ezumike nwa osisi, ma mgbe nwa osisi ga-etinye ya, enwere ike itinye ya. Enwere ike ịgwọ alaka dị afọ otu ugboro 2-3 ma ọ bụ fesa ya na a 0.2% zincte sulfate n'oge ọkọchị.
