Muab cov av thiab cov qoob loo nrog cov as-ham zoo tsis yog ib qho yooj yim. Hauv txoj kev npaj fertilization, cov ntsiab lus tseem ceeb tshaj plaws nitrogen (N), phosphate (P) thiab poov tshuaj (K) feem ntau saib hauv thawj qhov piv txwv. Tsis tas li ntawd, lwm cov ntsiab lus tseem ceeb calcium, sulfur thiab manganese yuav tsum tsis txhob hnov qab.
Av pH thiab cov ntsiab lus organic yog qhov tseem ceeb rau cov av thiab cov nroj tsuag noj qab haus huv; uas muaj hmoo tau txais kev saib xyuas ntau dua. Tom qab tag nrho, pH thiab cov ntsiab lus organic muaj qhov cuam tshuam loj rau kev muaj; Hauv lwm lo lus, qhov absorbability ntawm cov as-ham rau cov nroj tsuag. Ntxiv nrog rau cov ntsiab lus tseem ceeb, kab kawm manganese, zinc, tooj liab, hlau, boron thiab molybdenum kuj tseem ceeb heev rau kev loj hlob ntawm cov nroj tsuag.
Ban on mancozeb
Hauv ntau cov qoob loo xws li qos yaj ywm, dos, thiab paj qhov muag teev, cov kab mob fungicide mancozeb tau siv los tawm tsam ntau yam kab mob fungal. Vim hais tias mancozeb kuj muaj manganese thiab zinc raws li tus nqi ntxiv rau saum cov nyhuv fungicidal, cov qoob loo kuj tseem muab manganese thiab zinc tam sim ntawd thaum siv mancozeb. Raws li nws sawv, txawm li cas los xij, 2021 yog xyoo kawg uas mancozeb tau thov. Qhov kev txwv ntawm mancozeb yog li ntawd kuj muaj qhov tshwm sim rau txoj kev npaj fertilization.
Qhov tseem ceeb ntawm manganese thiab zinc rau cov nroj tsuag
Manganese thiab zinc yog qhov tseem ceeb rau ntau yam txheej txheem tseem ceeb hauv cov nroj tsuag, suav nrog photosynthesis. Lawv ua lub luag haujlwm ua kom cov qoob loo ntsuab. Yog li ntawd, ib tug deficiency yog thawj zaug pom nyob rau hauv ib tug daj ntseg ntsuab los yog daj discoloration ntawm nplooj. Tsis muaj manganese loj heev txawm ua rau tuag ntawm nplooj. Tsis tas li ntawd, cov nroj tsuag uas tsis muaj manganese muaj kev cuam tshuam ntau rau cov kab mob hauv av xws li hauv paus rot.
Hauv tshwj xeeb hauv cov av uas muaj pH> 6 thiab / lossis cov ntsiab lus organic siab tshaj 2.5 feem pua thiab ntev lub sij hawm qhuav, manganese deficiency yog qhov tseem ceeb. Calcareous loamy thiab lub teeb av nplaum av feem ntau cuam tshuam rau qhov tsis muaj manganese. Ntawm cov xuab zeb sib zog thiab cov av hauv hav, pH ntawm cov av tshwj xeeb yog qhov txiav txim siab heev rau seb puas muaj manganese deficiency tshwm sim.
Foliar fertilization
Siv cov chiv raws li kev thov av yog qhov zoo raws li qhov yooj yim fertilization; tab sis tsis yog ceev heev thiab siv tau zoo vim hais tias cov tshuaj siv tshuaj tiv thaiv nrog cov av nws tus kheej. Yog li ntawd, cov khoom noj khoom haus muaj tsawg thiab qee zaum tsis muaj nyob rau hauv tag nrho. Ib txoj hauv kev ncaj qha thiab ntau lub hom phiaj ntawm fertilization yog daim ntawv thov ntawm foliar fertilization. Kev tiv thaiv tsis txaus yuav tsum tau tiv thaiv ua ntej, tab sis thaum nws tshwm sim nws tus kheej thaum cog, qhov no tuaj yeem daws tau sai tshaj plaws nrog foliar chiv. Foliar fertilization feem ntau ua haujlwm tam sim ntawd: cov nroj tsuag absorbs cov as-ham tam sim ntawd thiab lawv yuav luag tam sim ntawd hauv cov metabolism ntawm nplooj, qhov twg cov nroj tsuag xav tau cov as-ham tshaj plaws. Kev tsis txaus feem ntau daws tau hauv ib lub lis piam.
Tshwj xeeb tshaj yog cov kab mob xws li manganese, boron, zinc thiab sulfur feem ntau nyuaj rau nqus, tshwj xeeb tshaj yog rau cov av uas muaj pH siab dua (pH> 6). Foliar fertilization tuaj yeem ua tau raws li qee zaum mob hnyav rau cov kab mob. Tsis tas li ntawd, koj tuaj yeem pub cov qoob loo zoo thiab ua tib zoo saib xyuas nrog foliar chiv, nyob rau hauv cov qauv kev cai lij choj. Nrog rau qhov siab tshaj plaws ntawm nitrogen, phosphate thiab tsiaj quav quav, nws tsis yog ib txwm ua tau kom tau raws li cov kev xav tau ntawm cov qoob loo. Ntxiv rau qhov yooj yim fertilization nrog cov foliar chiv zoo ua rau muaj txiaj ntsig zoo. Foliar chiv tuaj yeem siv ua ke nrog, piv txwv li, fungicides.
Cim foliar chiv muab sulfur, manganese thiab zinc
HU-MAN 15 yog ib qho tshwj xeeb foliar chiv uas tuaj yeem siv rau kev noj zaub mov zoo manganese hauv ntau cov qoob loo xws li qos yaj ywm, dos, beets, nplej, paj noob thiab legumes. HU-MAN 15 muaj manganese thiab sulfur, tov nrog ib tug tshwj xeeb humic acid complex. Zinc kuj tau ntxiv rau HU-MAN 15 kom muab cov nroj tsuag hluas pib qhov zoo. 150 g manganese, 218 g sulfur, 10 g zinc thiab 2 g magnesium yog muab rau ib liter. Humic acid ua kom muaj kev nqus tau zoo dua thiab kev ua haujlwm ntawm cov nroj tsuag thiab txhawb nqa kev thauj mus los ntawm cov zaub mov los ntawm cov nroj tsuag kom ua tiav cov txiaj ntsig siab tshaj plaws. HU-MAN 15 yog me ntsis acidic (pH 4.5) thiab yog li ntawd pab txhawb kom lub tank zoo sib xyaw thiab txhim kho qhov nqus ntawm cov tshuaj tiv thaiv qoob loo.
Qhov ntau npaum ntawm HU-MAN 15 yog 1-2 l / ha, yuav tsum tau siv rau hauv 200 litres ntawm cov kua tshuaj tsuag ib hectare. Daim ntawv thov no tuaj yeem rov ua dua raws li xav tau. Pib nrog foliar chiv ua ntej qhov teeb meem pom.
