Cov Zaub Zaub Zaub Noj Zaub Mov Cov Khoom Noj Tsis Txaus thiab Lawv Cov Kev Kho
Rau cov phooj ywg uas cog zaub hauv tsev cog khoom, qee zaum cov zaub tsis txaus ntawm cov zaub yog noj maj mam. Ntawm no kuv xav ceeb toom rau txhua tus neeg tias vim yog kev cog qoob loo tsis tu ncua ntawm cov zaub hauv tsev cog khoom, cov khoom noj khoom haus hauv av yuav raug txo lossis txawm tias tsis tuaj yeem ua tau raws li cov kev xav tau ntawm cov zaub thiab kev loj hlob, cuam tshuam rau cov qoob loo thiab cov zaub zoo, ua rau cov zaub. nutrient deficiency, uas yuav cuam tshuam ncaj qha rau lub tsev xog paj. Tag nrho cov txiaj ntsig kev lag luam ntawm kev cog qoob loo. Cov tsos mob thiab kev kho mob ntawm cov zaub zaub tsis muaj zaub mov tsis txaus yog qhia raws li hauv qab no:
1. Nitrogen tsis txaus
Cov tsos mob yog cov nroj tsuag luv luv, daj ntseg lossis liab nplooj, thiab qee cov nplooj tig daj; Cov xim qia kuj feem ntau hloov, loj hlob sai, thiab tig xim av tom qab ziab, nrog luv luv thiab nyias stems. Kev ntsuas kev kho mob: Thaum pom tias tsis muaj nitrogen, cov chiv nitrogen sai xws li ammonium sulfate thiab urea yuav tsum tau siv rau lub sijhawm, tab sis ammonium bicarbonate feem ntau tsis siv hauv tsev cog khoom.
2. Phosphorus tsis txaus
Cov nroj tsuag loj hlob maj mam, cov nplooj ua me me tab sis nyob twj ywm ntsuab, thiab txawm tias nplooj yuav tsaus thiab stems ua thinner. Kev ntsuas kho: siv superphosphate {{0}} kg / mu ua chiv; los yog tshuaj tsuag 0.3-0.5 feem pua cov tshuaj potassium dihydrogen phosphate rau ntawm nplooj thaum loj hlob.
3. Potassium deficiency
Cov nplooj yog lub teeb grey-ntsuab, nplooj nplooj tig daj thiab qhuav, thiab cov stems nyias thiab tawv. Kev ntsuas kev kho mob: Tam sim ntawd topdress ceev-ua chiv, xws li poov tshuaj sulfate, thiab lwm yam., los yog tshuaj tsuag 0.3-0.5 feem pua poov tshuaj dihydrogen phosphate tov rau ntawm nplooj.
4. Magnesium deficiency
Cov nplooj qub poob chlorosis thiab tig daj, tab sis cov hlab ntsha tseem ntsuab, cov nplooj ua nkig, nplooj nplooj dov, thiab qee zaum cov nplooj tuaj ntshav. Kev ntsuas kho: Txau 0.5 feem pua ntawm magnesium sulfate tov rau nplooj hauv lub sijhawm tom qab tshawb pom.
5. Boron tsis muaj peev xwm
Cov ntsiab lus kev loj hlob shrinks, browns thiab dries li, hom nroj tsuag yog tufted, thiab nplooj yog khoov, ua rau cov nplooj hlawv cov tsos mob. Txoj kev tswj hwm: siv {{0}}.5 kg ntawm borax ib mu li hauv paus chiv, los yog tshuaj tsuag 0.1-0.2 feem pua boric acid rau ntawm nplooj.
6. tooj liab tsis muaj peev xwm
Cov nplooj me me yog shrunken, cov nroj tsuag loj hlob tsis muaj zog, nplooj xim hloov, thiab nplooj nplooj tig dawb. Kev ntsuas kev kho mob: Txau 0.05 feem pua cov tshuaj tooj liab sulfate rau ntawm nplooj. Tsis tas li ntawd, kev siv cov chiv ntau dua tuaj yeem tiv thaiv qhov tshwm sim ntawm tooj liab tsis txaus.
7. Manganese tsis txaus
Lub mesophyll ntawm cov nplooj hluas yog necrotic, cov leeg tseem ntsuab, thiab nplooj poob tom qab. Kev ntsuas ntsuas: sim ua kom cov av nruab nrab, siv {{0}}} kg ntawm manganese sulfate ib mu raws li chiv, thiab topdress 0.2 feem pua manganese sulfate sab nraum cov hauv paus hniav.
8. Hlau tsis txaus
Cov nplooj me me qhia chlorosis ntawm cov leeg thiab yog xim daj-dawb, thiab thaum hnyav, tag nrho cov nplooj tig daj-dawb thiab qhuav. Kev ntsuas kho: tshuaj tsuag 0.1-0.2 feem pua ferrous sulfate tov rau ntawm nplooj
