Cov ntsiab lus ntawm zinc hauv cov qoob loo feem ntau yog ob peb ntu ntawm ib puas txhiab rau ob peb feem ib lab ntawm cov teeb meem tsis muaj teeb meem. Txawm hais tias cov ntsiab lus tseem ceeb heev, cov nyhuv yog qhov zoo. Piv txwv li, "shrunk seedlings", "txhav txhav", thiab "kab mob uas" hauv pob kws, "kabxeeb dawb" hauv cov kab tsuag txiv ntoo, thiab "kab mob bronze" hauv cov ntoo brunch yog txhua yam cuam tshuam rau qhov tsis muaj zinc. Cov. Yog li dab tsi yog lub luag haujlwm ntawm zinc hauv cov nroj tsuag? Peb yuav piav nws los ntawm cov hauv qab no.
(1) lub luag haujlwm ntawm zinc
1) raws li kev tivthaiv lossis activator ntawm qee yam enzymes:
Kev tshawb fawb tam sim no pom tias zinc yog ib feem ntawm ntau cov enzymes. Ntau cov enzymes tseem ceeb hauv cov nroj tsuag (xws li dej cawv qhuav, tooj-zinc Superoxide dismutase, thiab lwm yam) yuav tsum muaj kev cuam tshuam lawv lub cev muaj zog. Tsis tas li ntawd, Zinc yog ib tug activator ntawm ntau cov enzymes. Yog zinc tsis muaj kev tawm tsam, cov haujlwm ntawm proteion thiab nitrate reductase hauv cov nroj tsuag yuav tau txo ntau heev. Ua ke, lawv muaj kev cuam tshuam ntau dua rau cov nroj tsuag kev loj hlob thiab cov metabolism.
2) cuam tshuam rau carbohydrates:
Cov nyhuv ntawm zinc rau cov carbohydrates yog tsuas yog ua tiav los ntawm kev lag luam photosynthesis, thiab qee cov enzymes uas xav tau zinc kuj tseem muaj kev koom tes hauv cov metabolism tseem ceeb. Thaum Zinc tsis muaj qhov tsis txaus, cog cov ntsiab lus photosynthes yuav tau txo qis heev. Vim tias zinc tsis txaus yuav cuam tshuam enzyme kev ua si, nws yuav ua rau txo qis hauv chlorophyl cov ntsiab lus, thiab kev txawv txav ntawm cov mesophyllasts.
3) Txhawb cov protein metabolism protein:
Txij li zinc yog ib feem ntawm ntau cov enzymes hauv cov txheej txheem protein hauv zinc, tus nqi thiab cov ntsiab lus ntawm cov khoom siv protein yuav raug cuam tshuam. Cov nyhuv ntawm zinc ntawm cov nroj tsuag protein metabolism tseem cuam tshuam los ntawm lub teeb siv.
(2) Siv zinc
1. Zinc Chiv yog qhov zoo tshaj plaws ntawm cov qoob loo uas rhiab rau cov pob kws, taum pauv, taum nqaij, txiv hmab txiv ntoo, txiv lws suav, thiab lwm yam.
2. Siv los ua paus chiv txhua lwm xyoo: Siv 20-25 kilograms ntawm zinc sulfate ib hectare raws li puag thaum pib chiv. Nws yuav tsum tau thov komyees thiab txhua lwm xyoo. Vim tias zinc Fertilizer muaj cov nyhuv ntev hauv av, nws tsis tas yuav siv txhua txhua xyoo.
3 Kho nrog tshuaj tua kab, tsis li ntawd cov nyhuv yuav cuam tshuam.
4. Tsis txhob sib tov nws nrog phosphote chiv: Vim tias zinc-phosphorus muaj kev sib xyaw nrog cov av noo noo, thiab khawb rau hauv av nrog rau cov av cog qoob loo, txwv tsis pub cov Cov nyhuv ntawm zinc chiv yuav muaj kev cuam tshuam.
5. Tsis txhob thov cov ntaub ntawv dete tab sis faus nws hauv av: thaum ua ntawv thov zinc sulfate, thov txog 15 kilograms ntawm zinc sulfate ib hectare. Tom qab trenching thiab npog nrog av, muaj txiaj ntsig ntawm daim ntawv teev nto yog neeg pluag.
6. Tsis txhob tsau lub keeb kwm ntawm cov keeb kwm rau ntev ntev, thiab kev xav tau yuav tsum tsis txhob siab dhau. Ib qho kev xav ntawm 1% yog qhov tsim nyog thiab lub sijhawm soaking yog txaus rau ib nrab ib feeb. Yog tias lub sijhawm ntev dhau, phytotoxicity yuav tshwm sim.
7. Kev siv txau muaj cov txiaj ntsig zoo: Siv zinc sulfate daws nrog lub tswv yim ntawm 0.1 ~ 3 zaug, tab sis ceev faj kom tsis txhob nchuav rau hauv lub plawv nplooj kom tsis txhob hlawv cov nroj tsuag.
(3) kev phom sij ntawm cov zinc ntau dhau:
Dab tsi yog qhov kev phom sij ntawm zincy zinc? Piv txwv li, cov hauv paus hniav thiab nplooj yuav loj hlob qeeb, cov tub ntxhais hluas cov ntu yuav tig ntsuab lossis liab-xim av me me yuav tshwm sim ntawm cov chaw qis ntawm cov kav, petioles, thiab nplooj. Lub hauv paus elongation yog tabkaum.
