Zinc Fertilizer Raw Khoom

Hom zinc fertilizer cov khoom nyoos feem ntau muaj: heptahydrate zinc sulfate, hexahydrate zinc sulfate, zinc citrate zinc, zinc citrate zinc, zinc citrate, thiab nano zinc oxide.

1. Zinc Fertilizer Raw Khoom

- Zinc Sulfate: tsis muaj xim lossis dawb muaju, granules, thiab hmoov uas tsis muaj ntxhiab tsw. Melting point: 100 ° C, nrog astringent saj. Ntom ntom: 1.957 g / cmà (25 ° C). Yooj yim soluble hauv dej, cov kua aque yog acidic, thiab me ntsis soluble hauv ethanol thiab glycerol.

- Zinc Nitrate: tsis muaj xim crystal hauv tetragonal system, hygroscopic, yuav tsum muab cia rau hauv qhov tsaus ntuj. Melting taw tes: 36 ° C, npau tes boiling: 105 ° C, ntom ntom: 2.065 g / cm³.

- Zinc chloride: Melting taw tes: 283 ° C, npau tes boiling: 732 ° C, ntom: 2.91 g / cm³. Zoo nkaus li hmoov dawb crystalline, yooj yim soluble hauv dej, etholule hauv kua ammonia, thiab solubility ntawm 2095 grams ntawm 20 ° C.

- Zinc Oxide: Kuj tau hu ua zinc oxide hmoov, zinc dawb, lossis zinc dawb compound nrog cov tshuaj lom neeg zno thiab txoj haujlwm molecular ntawm 81.39 g / mol. Nws yog cov tawv dawb thiab ib daim ntawv ntawm zinc oxide. Zinc Oxide yog insoluble hauv dej thiab ethanol, tab sis soluble hauv cov kua qaub, sodium hydroxide tov, thiab ammonium chloride. Nws yog amphoheric oxide thiab tuaj yeem hnov ​​mob nrog cov kua qaub lossis hauv paus los ua cov ntsev thiab dej.

- Edta Zinc: sodium ethylenediamette zinc, tseem hu ua Eddium disodium zinc, edta-zn 14%, nrog rau cov dej ph (1% dej soluble) ntawm 6.0-7.0. Zog: hmoov dawb.

- ZINC CITSTrate: Kuj tseem hu ua citric acid zinc, zinc daj, lossis tri-zinc citrate, yog soluble me ntsis hauv dej; Soluble hauv dilute acolutions thiab alkaline daws, tshwm sim li cov hmoov tsis muaj kob, thiab me ntsis solubility hauv dej 2.6 g / l.

2. Kev ua haujlwm ntawm zinc hauv cov qoob loo ntawm cov qoob loo

Zinc feem ntau ua haujlwm ua cov khoom sib xyaw ua ke thiab cov ua haujlwm ntawm cov txheej txheem hydrolysis, cov txheej txheem redein, thiab protein synthesis ntawm cov tshuaj nyob rau hauv cov qoob loo. Nws tuaj yeem txhawb txoj kev loj hlob ntawm kev ua me nyuam nruab nrog hauv cov qoob loo thiab txhim kho lawv txoj kev tiv thaiv kom ntxhov siab. Zinc yog qhov tseem ceeb pib rau cov nroj tsuag, nrog zinc cov ntsiab lus tseem ceeb xws li 20-100 mg / kg. Thaum lub Dinc cov ntsiab lus qis dua 20 mg / kg, cov tsos mob ntawm zinc tsis muaj peev xwm tshwm sim.

Zinc yog ib feem ntawm ntau cov enzymes, suav nrog superoxide dismutase, thiab lwm yam tshuaj, thiab lwm yam tshuaj, ua lub luag haujlwm tseem ceeb hauv kev tswj hwm cov nroj tsuag ib txwm muaj. Nyob rau hauv aulexin metabolism, cov synthesis ntawm IAA tus ua ntej, yuav tsum tau zinc, thiab zinc tsis muaj cov ntsiab lus hauv pobkws los ntawm 30%, cuam tshuam rau cov hauv paus kev loj hlob. Hauv cov metabolism, zinc tsis txaus ua rau txo kom txo qis RNA muaj peev xwm, cuam tshuam cov protein synthesis. Kev tshawb fawb qhia tau hais tias tso cai zinc fertilizer tuaj yeem nce cov protein ntau hauv milled mov los ntawm 6.9%.

Hauv cov metabolism carbohydrate, zinc txhawb nqa chlorophyllase thiab txhim kho lub carbonic anhydresis, pab txhawb cov carbonylase, pab txhawb cov carbon pab txheej txheem. Zinc kuj tseem yog lub luag haujlwm tseem ceeb hauv kev ua kom cov pa roj oxygen ua rau cov nroj tsuag thiab txhim kho lawv cov kev ntxhov siab. Nyob rau hauv thaum ntxov kev kawm noj mov thaum ntxov, thov zinc tau txo qis kev puas tsuaj los ntawm tsawg kub rau cov yub. Zinc def tsis txaus hauv cov mov tsuas yog tshwm sim thaum lub caij cog qoob loo thiab kev loj hlob ntawm cov nplooj zeeg dawb, nrog lub hauv paus loj, thiab muaj mob hnyav, xim av me me tshwm rau ntawm nplooj.
