I. Mitundu ya mitete ya zinzi
Za feteleza ndi zida zomwe zimapereka zitsulo ngati michere yoyamba yazomera. Nthawi zambiri feteleza wa zinc pamsika amaphatikiza zinc sulfate, zinc chloride, zinc carbonate, ndi zinc chlade. Mwa izi, zinc sulfate Helphate Heppate Heptute (Znsoo4 · 7h, wokhala ndi ZAN KANO) ndi zinc chloride (Zncl2, omwe ali ndi ZN) amagwiritsidwa ntchito. Zonsezi ndi zinthu zoyera zosungunuka mosavuta m'madzi, ndipo chisamaliro chiyenera kumwedwa kuti chisateteze mchere wa zinc kuti usakhazikike ndi phosphorous panthawi yogwiritsira ntchito.
Ii. Mitundu ndi ntchito za feteleza wa zinc
Zinc ndi chimodzi mwazinthu zofunika kwambiri zazomera, zophatikizidwa ndi mawonekedwe a zn. + Kusunthika kwa zinc mkati mwa mbewu kumakhala koyenera. Zikinikiridwa mosapita m'mbali kapangidwe ka mabwalo mahomoni; Ngati zinc ndiosowa, zomwe zili momwe mahomoni zimayambira ndi masamba amachepetsa, ndikupangitsa kukula kuti asunthire ndikupangitsa mbewu zazifupi. Kuphatikiza apo, zinc amachita ngati gulu la ma enzymers ambiri, atakhudzidwa ndi kagayidwe ka katemera ndi nayitrogeni mu zomera, potero kuthandizira photosynthesis. Zinc imathandiziranso kuphwanya mbewu, zimawonjezera kulemera kwa njere, ndikusintha chiwerengero cha mbewu kuti zitheke.
Iii. Kugwiritsa ntchito feteleza wa zinc
Ngati zogwiritsira ntchito zachilengedwe mu dothi ili pakati pa 0,5 mg / kg ndi 1.0 mg / kg / kg ndi makilogalamu a zinc, kugwiritsa ntchito zitsamba zambiri kumatha kukulira zipatso. Njira zogwiritsira ntchito ma feteleza za zinc zimaphatikizapo kugwiritsa ntchito feteleza wa feteleza, wopaka kwambiri, ndi feteleza wa mbewu. Feteleza innible hutters nthawi zambiri imagwiritsidwa ntchito feteleza woyenda, pogwiritsa ntchito 1-2 makilogalamu a zinzi la zinzi pa acpete pa feteleza wa acnic. Kwa minda yokhala ndi kuchepa kwake pang'ono, zoyambiranso kuyenera kuchitika zaka 1-2; Kwa minda yocheperako, kugwiritsa ntchito kumatha kuchepetsedwa ndikuchitika chaka chilichonse kapena chaka chilichonse. Monga feteleza wokhazikika, zinc nthawi zambiri amagwiritsidwa ntchito ngati wopukutira wa FILY, ndi ndende ya 0.02% -0.1% -0.1% -0.1% -0.5% ya chimanga ndi mpunga. Mpunga ukhoza kuthiridwa ndi 0,2% solin sulfate solution pachimake, ndikuwombera, ndi masamba otuluka; Mitengo yazipatso imatha kuthiridwa ndi 5% solin sulfate pamwezi umodzi asanadutse bud, ndipo pambuyo pa kuthyola mphukira, 3% -4% imatha kuyikidwa. Nthambi za chaka chimodzi zitha kuthandizidwa katatu kapena kupopera mbewu mankhwala 0,2% solfate yankho la chilimwe.
Iv. Makhalidwe a Zilicani feteleza
1. Miteyo ya zincin ndi yothandiza kwambiri ikagwiritsidwa ntchito pazomera zam'mimba, monga chimanga, mafunde, ma soya, nyemba, mitengo yazipatso, ndi tomato. 2. Kugwiritsa ntchito tikulimbikitsidwa mu nthaka yopanda zinc - ndizothandiza kugwiritsa ntchito feteleza wa zinc panthaka ya zincin, pomwe sikofunikira mu dothi lomwe silikusowa zinc.
