Umanyolo we-micronutrient - Umanyolo we-zinc

I. Izinhlobo zomanyolo we-zinc

Umanyolo we-zinc yizinto ezihlinzeka nge-zinc njengezakhi eziyinhloko zezitshalo. Umanyolo osetshenziswayo we-zinc emakethe uhlanganisa i-zinc sulfate, i-zinc chloride, i-zinc carbonate, i-zinc onide. Phakathi kwalokhu, i-zinc sulfate heptahydrate (znso4 · 7h2o, equkethe cishe ama-23% zn) kanye ne-zinc chloride (zncl2, equkethe cishe ama-47.5% zn) asetshenziswa kakhulu. Zombili lezi zinto ezimhlophe ze-crystalline ezincibilikayo kalula emanzini, futhi ukunakekelwa kufanele kuthathwe ukuvikela ama-zinc usawoti ukuthi alungiswe yi-phosphorus ngesikhathi sohlelo lokusebenza.

II. Amafomu nemisebenzi kamanyolo we-zinc
I-Zinc ingenye yeMicronutrients ebalulekile yezitshalo, egxile ngesimo se-zn2 ye-ZN2. +. Ukuhamba kwe-zinc ngaphakathi kwezitshalo kulinganiselwe. I-zinc ithonya ngokungaqondile kokuhlanganiswa kwama-hormone okukhula ezitshalweni; Lapho i-zinc isephutha, okuqukethwe ama-hormone okukhula eziqubeni nasezinhle kuncipha, okubangela ukukhula ku-stagnate futhi kuholele ezitshalweni ezimfushane. Ngokwengeziwe, i-zinc isebenza njengesishoshovu sama-enzyme amaningi, ukuba nomthelela obanzi ku-carbon ne-nitrogen metabolism ezitshalweni, ngaleyo ndlela kusiza izithombe ezinhle. I-zinc ibuye ithuthukise ukumelana nezitshalo 'ekucindezelweni, inyuse isisindo sokusanhlamvu, futhi iguqule isilinganiso sembewu iziqu.

III. Ukusetshenziswa komanyolo we-zinc
Lapho okuqukethwe okusebenzayo kwe-zinc emhlabathini kuphakathi kuka-0.5 mg / kg kanye ne-1.0 mg / kg, ukusebenzisa umquba we-zinc engcupheni yeze-carcareous kanye nezinkundla zokuthenga eziphezulu kusengakhulisa izivuno futhi kuthuthukise ikhwalithi yezitshalo. Amasu okusebenzisa amanyolo we-zinc afaka phakathi kumanyolo we-basal, ama-toplerring, kanye nomanyolo wembewu. Umanyolo we-incuble zinc ngokuvamile usetshenziswa njengomanyolo we-basal, ngesilinganiso sohlelo lokusebenza lwe-1-2 kg ye-zinc sulfate nge-acre ngayinye, engaxutshwa ngomanyolo we-acidic ngokomzimba. Ezinkani ezinokuntuleka kwe-zinc, ukuvela kufanele zenzeke njalo eminyakeni eyi-1-2; Ngezinkambu ezingajeziswe ngokulingana, uhlelo lokusebenza lungancishiswa futhi lwenziwe njalo ngonyaka noma njalo ngonyaka. Njengoba i-toplerressing, umanyolo we-zinc uvame ukusetshenziswa njengezithombo ze-foliar, ngokuhluzwa okujwayelekile kwe-0.02% -0.1% i-zinc sulfate solution yezilimo ezijwayelekile, kanye ne-0,1% -0.5% yezombila nelayisi. Ilayisi lingafafazwa ngesisombululo esingu-0.2% ze-zinc sulfate eTillering, ebhuthini, kanye nezigaba zezimbali; Izihlahla zezithelo zingafafazwa ngesisombululo esingu-5% ze-zinc sulfate inyanga eyodwa ngaphambi kokuphuka kwe-bud, nangemva kokuphumula kwe-bud, ukuhlanganiswa okungu-3% -4% kungasetshenziswa. Amagatsha aneminyaka eminye ubudala angalashwa izikhathi ezi-2-3 noma afafazwe nge-0.2% Zinc Sulfate Solution ekuqaleni kwehlobo.
