Yuav ua li cas tiv thaiv tsis muaj zaub mov noj nyob rau hauv zaub greenhouses

Qhov "malnutrition" ntawm zaub zus nyob rau hauv zaub greenhouses tsis zoo li qub. Qhov no yog tshwm sim los ntawm qhov tsis muaj cov khoom noj sib txawv. Tus editor hauv qab no yuav muab cov ncauj lus qhia ntxaws rau koj txog qhov teeb meem no.

1) Phosphorus deficiency.

Cov tsos mob yog hais tias cov nroj tsuag loj hlob qeeb, nplooj yuav me me tab sis tsis poob ntsuab, los yog txawm tias nplooj yuav tsaus, stems ua thinner, thiab lwm yam. Yuav kom ua tau, {{0}} kg/mu ntawm superphosphate tuaj yeem siv los ua cov chiv chiv, lossis thaum lub sijhawm kev loj hlob, nplooj yog Txau 0.3 feem pua ​​-05 feem pua ​​​​phosphoric acid.

2) Nitrogen deficiency.

Cov tsos mob yog cov nroj tsuag dwarf, nplooj daj lossis liab, thiab qee cov nplooj tig daj; Yan feem ntau hloov, thiab hloov sai, xim av tom qab ziab, thiab luv luv thiab nyias stems. Cov tshuaj nitrogen ua kom nrawm, xws li urea, tuaj yeem siv rau lub sijhawm. Nyob rau hauv lub tsev xog paj zoo li

3) Potassium deficiency.

Cov tsos mob yog tias cov nplooj zaub yog lub teeb grey-ntsuab, nplooj nplooj tig daj thiab qhuav, thiab cov stems nyias thiab tawv. Cov chiv ua kom nrawm xws li potassium sulfate tuaj yeem siv tam sim ntawd, lossis 0.3 feem pua ​​-0.5 feem pua ​​​​poov tshuaj dihydrogen phosphate tuaj yeem txau rau ntawm nplooj. daws.

4) Manganese deficiency.

Cov tsos mob yog necrosis ntawm mesophyll ntawm cov nplooj me, tab sis cov leeg tseem ntsuab, thiab nplooj yog defoliated tom qab. Txoj kev zoo tshaj plaws yog ua kom cov av nruab nrab, siv 1.4 kg ntawm manganese sulfate ib mu ua chiv, thiab topdress nrog 0.2 feem pua ​​manganese sulfate.

5) Copper deficiency.

Cov nplooj me me qhia tias shrinkage, cog kev loj hlob tsis muaj zog, nplooj hloov xim, thiab nplooj nplooj tig dawb. Txau 0.05 feem pua ​​tooj liab sulfate tov rau ntawm nplooj nplooj, thiab siv ntau cov organic chiv los tiv thaiv qhov pib ntawm tooj liab deficiency.

6) Hlau deficiency.

Cov nplooj hluas qhia chlorosis nruab nrab ntawm cov leeg, yellowish dawb, thiab tag nrho cov nplooj tig daj daj thiab qhuav nyob rau hauv mob hnyav. {{0}}.1 feem pua ​​~ 0.2 feem pua ​​​​ferrous sulfate tov tuaj yeem txau rau ntawm nplooj nplooj.

7) Boron deficiency.

Cov ntsiab lus loj hlob yog shriveled, xim av thiab qhuav, hom nroj tsuag yog clump-zoo li, nplooj yog tortuous, thiab cov tsos mob ntawm nplooj hlawv.

8) Magnesium deficiency.

Cov nplooj qub poob ntsuab thiab tig daj, tab sis cov hlab ntsha tseem ntsuab, cov nplooj ua nkig, cov nplooj nplooj tau dov, thiab qee zaum cov nplooj yog ntshav-liab. Txau 0.5 feem pua ​​magnesium sulfate tov rau ntawm nplooj nyob rau hauv lub sij hawm.
