Micronutrient fettilizer - zinc fettilizers

I. Mhando dzeZinc fettilizers

Zinc fettilizer ndeyezvishandiso zvinopa zinc seyekutanga hutano kune zvidyarwa. Kazhinji inoshandiswa zinc fettiera mumusika unosanganisira zinc sulfate, zinc chloride, zinc kabhoni, chekare zinc, uye zinc oxide. Pakati peizvi, zinc sulfate heptahydrate (znso4 · 7h2o, ine angangoita 23% zn) uye znc2, ine anenge 47.5% zn) inowanzoshandiswa. Zvese zviri zviviri zvevachena chena crystalline zvinhu zvine mwero mumvura, uye chengetedzo chinofanira kuendeswa kudzivirira zinc salts kubva pakugadziriswa ne phosphorus panguva yekunyorera panguva yekushandisa.

Ii. Mafomu uye mabasa e zinc fettilizers
Zinc ndeimwe yezvakakosha micronutraments kune zvidyarwa, zvakanyudzwa muchimiro checation zn2 +. Kufamba kweZinc mukati mezvirimwa zviri pakati nepakati. Zinc zvisina kunangana zvisina kunanga zvinopesvedzera synthesis yekukura mahormone muzvirimwa; Zinc painenge isina kukwana, zvirimo zvekukura mahormone mune stems uye mabhudhi anoderera, zvichikonzera kukura kuti udzikise uye zvichikonzera zvidyarwa zvipfupi. Pamusoro pezvo, zinc zviito semutambi wemazhinji enzymes, aine maitiro akawandisa paCarbon uye nitrogen metabolism mune zvinomera, nekudaro photosynthesis. Zinc zvakare anowedzera kuramba 'kupokana nekumanikidza, anowedzera kurema kwezviyo, uye anoshandura huwandu hwembeu dzakateyiwa.

III. Kushandiswa kweZinc fettilizers
Kana iyo inoshanda zinc zvirimo muvhu iri pakati pe 0.5 mg / kg, kg, yekunyorera ma zinc fettierazers mune ivhu remahara uye minda yakakwirira-inobereka inogona kuramba ichingorera uye ichivandudza gopi mhando. Maitiro ekushandisa eZinc fettilizers anosanganisira kuvashandisa sevasina mafetera, topdressing, uye mhodzi fetizaders. Insoluble Zinc fettilizers inowanzo shandiswa seBasal Fettiera, neyakagadziriswa yeZinc Sulfate paCheki, iyo inogona kusanganiswa neyepicial acidizers. Kuminda nekushomeka kwezvinhu zvinyoro-nyoro, kuongorora kunofanira kuitika makore ese 1-2; Zvezvemari zvine mwero mwero, application inogona kuderedzwa uye kuitiswa gore rega rega kana rimwe nerimwe rimwe gore. Sezvo to topdressing Mupunga unogona kupfirwa ne 0,2% zinc sulfate mhinduro pamupombi, kubhodhara, uye matanho ekuyerera; Miti yemichero inogona kupfirwa ne5% zinc sulfate solution mumwe chete usati watererwa, uye mushure meBud zororo, 3% -4% yekusangana inogona kuiswa. Matavi ane makore okukura anogona kurapwa katatu kana akapfirwa ne1,2% zinc sulfate mhinduro muzhizha kutanga.
