Ntau cov as-ham yog indispensable tshuaj nyob rau hauv kev loj hlob ntawm strawberries. Nyob rau hauv xyoo tas los no, nrog kev nce ntxiv ntawm kev cog qoob loo ntawm strawberry, vim muaj qee qhov xwm txheej, strawberry as-ham deficiency tau dhau los ua pom tseeb. Yog li, dab tsi yog cov tsos mob ntawm strawberry deficiency?
Cov tsos mob ntawm Strawberry Nutrient Deficiency
(1) Nitrogen deficiency
Thaum strawberries tsis muaj nitrogen, nplooj pib tig daj ntsuab, thiab tom qab ntawd cov npoo serrated tig liab, maj mam loj hlob los ntawm sab nraud, thiab txawm tias tag nrho cov nplooj tig txiv kab ntxwv liab.
Raws li qhov tsis txaus nitrogen txuas ntxiv mus, cov xim xim av ntawm cov nplooj ntoo uas paub tab tom ntej yuav ntxaum thiab cov nplooj nplooj tshwm xim av. Kev loj hlob hauv paus yog inhibited, qhov hnyav poob, thiab cov nroj tsuag tawm los tsawg.
(2) Phosphorus deficiency
Thaum cov txiv pos nphuab tsis muaj phosphorus, lawv thawj zaug tshwm ntshav ntawm cov leeg zoo ntawm cov nplooj qub, thiab tom qab ntawd cov hlab ntsha thicker tig xiav ntshav. Tag nrho cov nplooj tig xiav ntshav, thiab txoj kev loj hlob ntawm creeping qia tsis muaj zog.
(3) Potassium deficiency
Thaum strawberries tsis muaj poov tshuaj, thawj qhov yog tias cov lus qhia serrated ntawm nplooj nplooj tig liab thiab txhim kho sab hauv. Lub hauv paus ntawm midrib thiab nplooj tsis hloov xim, tab sis nyob twj ywm ntsuab. Lub creeping stems yog luv thiab nyias.
(4) Calcium deficiency
Thaum cov txiv pos nphuab tsis muaj calcium, thawj qhov yog tias cov nplooj ntawv tshiab tsim los ua scorched, nplooj curl, tab sis cov petioles yog qhov qub. Raws li cov tsos mob tshwm sim, cov nplooj tsim tshiab distortion maj mam ua hnyav.
Nyob rau hauv nruab nrab ntawm nplooj ntawm cov laus creeping qia seedlings, lub teeb liab doog xim av kab txaij yog tsim thiab poob ntsuab. Niam cog 1 feem ntau tsis pom cov tsos mob chlorosis, tab sis cov tsos mob no tuaj yeem tshwm sim thaum tsis muaj calcium ntau heev. Cov nroj tsuag tsis muaj calcium feem ntau muaj cov kab mob tsis zoo, cov txiv hmab txiv ntoo tsawg dua, thiab cov txiv hmab txiv ntoo deformed.
