Nyob rau hauv thaum ntxov qib ntawm poov tshuaj tsis txaus,LAUG COGs qhia qeeb kev loj hlob thiab cov nplooj ntsuab tsaus. Cov yam ntxwv tseem ceeb ntawm cov poov tshuaj tsis txaus: feem ntau cov qub nplooj thiab liab thiab xim av, thiab thaj av thiab thaj chaw ze cov leeg nyob twj ywm ntsuab. Raws li cov degree ntawm poov tshuaj yuav nce, tag nrho cov nplooj ntoos hloov xim av lossis qhuav, necrotizes thiab poob tawm; Qee cov nplooj ntoo cog yog tooj, curling downward, nrog bulging mesophyll cov ntaub so ntswg ntawm nplooj nplaim thiab sunken leeg. Thaum cov nroj tsuag muaj txiaj ntsig nyob rau hauv poov tshuaj, lub hauv paus ntsiab lus kuj tau puas ntau, muaj cov cag, tig thaum muaj mob loj, thiab chaw pw ntawm thaj chaw hauv paus. Thaum cov nroj tsuag nyom tsis txaus nyob rau hauv poov tshuaj, xim av me tshwm rau ntawm nplooj qis, thiab muaj cov tsos mob loj, tib tus tsos mob tshwm sim ntawm nplooj tshiab. Cov nplooj yog mos thiab drooping, cov qia yog nyias thiab tsis muaj zog, thiab cov internodes luv; Thaum cov nroj tsuag leguminous yog qhov tsis txaus nyob rau hauv poov tshuaj, ntsuab ntsuab yuav tshwm sim thawj zaug, thiab tom qab ntawd tig daj, tsim cov nplooj. Thaum muaj mob hnyav, cov nplooj ntoo yuav scrch thiab caws qis qis, thiab cov xim av me me yuav txhim kho sab hauv raws qhov chaw nruab nrab. Cov nplooj epidermis poob dej thiab shrinks, cov nplooj ntoo saum npoo av lossis me me scorches thiab ntog tawm, thiab cov nroj tsuag hnub nyoog thaum ntxov.
Kuv yuav ua li cas yog tias cov nyom tsis muaj cov poov tshuaj? Cov poov tshuaj tsis yog tsuas yog ib qho tseem ceeb uas noj zaub mov rau cog lub neej, tab sis kuj yog ib ntawm peb yam ntawm cov chiv. Cov ntsiab lus ntawm cov poov tshuaj hauv cov nroj tsuag yog ob tsuas yog rau nitrogen. Tsim Nyog Siv Potassium Furtilizer tuaj yeem txhim kho cov photosynthesis ntawm cov nyom nroj tsuag thiab lawv cov kev tawm tsam rau cov kab mob thiab kab tsuag. Yog tias cov tsos mob ntawm poov tshuaj tsis txaus yog pom hauv cov tshuaj tswj poov tshuaj (xws li potassium sulfate (poov tshuaj ntsev, thiab lwm yam) thiab tswj tau. Poov tshuaj chloride thiab poov tshuaj sulfate yog ob qho tib neeg ceev-ua chiv uas tuaj yeem siv los ua paus chiv thiabSaumddressingCov. Nws yog qhov zoo tshaj plaws kom siv cov poov tshuaj sulfate rau acidic av thiab potassium nitrate rau cov av alkaline.
Yog tias cov nyom tau muaj cov tsos mob saum toj no, cov kev hauv qab no tuaj yeem siv los daws nws:
1. Thov tsawg nitrogen chiv thiab dej tam sim ntawd tom qab thov nitrogen chiv.
2. Siv cov khoom lag luam uas muaj cov amino acids thiab kab kawm kom rov qab thiab cov kab cim ntxiv.
3. Thov Potassium Sulfate 2kg / Sijhawm.
