Kua ntoo yog, tej zaum, feem ntau cov tsoos thiab habitual neeg nyob ntawm peb lub vaj. Tag nrho peb ntawm txij thaum yau thiaj li hlub muaj kua txiv apples . Tiam sis tej lub sij hawm peb pom cov nplooj liab liab tshwm ntawm cov tsob ntoo kua. Qhov no nce tau ntau cov lus nug: puas yog qhov txaus ntshai? vim li cas ho muaj li no? yuav ua li cas nrog kev phem li no? Peb yuav sim nkag siab txog qhov teeb meem thiab nrhiav txoj hauv kev los daws qhov teeb meem.
Ua rau ntawm nplooj liab liab ntawm kua
Qhov laj thawj yog vim li cas muaj nplooj liab liab tshwm ntawm cov ntoo hauv qab, muaj ntau ntau. Cov tseem ceeb yog:
- Tsis muaj cov kev pab cuam. Thiab ib qho ntawm peb - magnesium, phosphorus los yog manganese - tuaj yeem ploj lawm. Nrog rau ib qho tsis muaj magnesium, cov nplooj qis pib pib plhws, thiab lawv caug, pib ntawm qhov nruab nrab. Maj mam, cov sawv ntawm nplooj kuj los ua purplish liab. Qhov txaus ntshai ntawm ib tug tsis muaj magnesium yog tias lub kua ntoo tolerates lub caij ntuj no zoo dua.
- Thaum muaj ib qho tsis muaj phosphorus, cov nplooj poob lawv cov xim ntsuab khaus ua ntej, lawv kis tau ib qho tooj liab, thiab tom qab ntawd ces cov petioles thiab cov leeg tsim liab ploj. Blossoming kua ntoo nrog phosphorus deficiency tom qab pw, thiab txiv hmab txiv ntoo paub tab ntev dua. Qhov txias tsis kam ntawm cov ntoo kuj ntog.
- Thaum qhaj ntawv ntawm manganese, sab saum toj nplooj ntawm Kua ntoo yog them nrog liab los yog dawb me ntsis. Nyob rau tib lub sij hawm tawm los txo, thiab saj ntawm apples yog poob, ua tshiab.
- Kab tsuag yog ob qhov laj thawj vim li cas cov kua ntoo muaj liab nplooj. Thiab thawj zaug ntawm daim ntawv yog lub kua aphid. Cov kab ua lays qe nyob rau hauv lub bark ntawm lub kua ntoo, thiab nyob rau hauv lub caij nplooj ntoos hlav lub larvae pub on nws juices, ua lub nplooj rau wither, ntswj, tig liab nrog ib tug Cherry los yog yellowish tinge.
- Mechanical kev puas tsuaj tuaj yeem ua rau liab liab ntawm nplooj ntawm lub tsob ntoo kua. Piv txwv, yog tias lub thoob ntim nrog lub xaim los yog ib txoj kab nuv ntses. Cov nplooj ntawm coj ib feem ntawm tsob ntoo tau ib tug crimson tsos nqaij daim tawv.
Txoj kev ntawm combating liab nplooj ntawm Kua
Nws yog ib qho tseem ceeb kom paub txiav txim yog vim li cas cov kua ntoo nplooj yog them nrog liab pob, ces tam sim ntawd pib mus rau kev kho mob.
Yog li, yog hais tias yog vim li cas rau qhov shortage ntawm cov as-ham:
- Magnesium deficiency yog kho los ntawm kev txau cov ntoo kua txhua txhua 10 hnub nrog tov tshuaj magnesium sulfate (20 g magnesium ib 10 liv dej), 4 sprayings raug tso cai;
- tsis muaj phosphorus tuaj yeem ua kom them taus los ntawm kev pub phosphorite lossis superphosphate;
- nrog ib shortage ntawm manganese txau nrog ib tug daws ntawm manganese sulphate ua ntej thiab tom qab Bud buds.
Nrog kab tsuag sib xyaw nrog cov tshuaj tua kab thiab cov khoom noj hauv tsev ua zoo li decoction ntawm haus luam yeeb, chamomile thiab citrus. Yog tias koj tsis to taub tias vim li cas liab qoob loo tshwm rau ntawm nplooj ntoo, kuaj xyuas tsob ntoo rau qhov kev puas tsuaj thiab, yog tias ua tau, tshem tawm cov teebmeem no.
