Leaf chlorosis: incazelo, izithombe, izindlela ukulawula

Noma yimuphi umuntu osebenza engadini ebhekene eside ezifana leaf chlorosis. isifo Plant kuzibonakalisa i ezingezona ezemvelo (-season) yellowing kanye leaf ukuwa. Imbangela lesi sifo itholakala ukwephulwa we-chlorophyll ekwakhekeni, ngakho - ukunciphisa umsebenzi ye-photosynthesis. Ihamba ngaleyo ndlela ungase ulahlekelwe umbala, hhayi ngokuphelele kuphela kodwa futhi kancane futhi entsha (abasha) amahlumela namaqabunga ancipha kubonakale. Emaphethelweni leaf blade ngokuvamile wasonta, efihlekile kwakhiwa (ngemibala) kukhona sikhubazekile. adubule amathiphu Kuphakathi enganamandla kakhulu noma Shrunken.

Leaf chlorosis kungaba ezithathelwanayo (ukungcoliswa kungenzeka ezinye izitshalo) kanye non-esithathelanayo (ukwephula imithetho nemikhuba kwezolimo). Cabanga chlorosis ngokuningiliziwe.

Okokuqala - leaf chlorosis (Photo izitshalo itheleleke), lapho, njengesibonelo - imivini:

chlorosis ezithathelwanayo amahlamvu yamagilebhisi

Abalimi bakubize ngokuthi "leaf ibala" futhi "KaMose yellow". Libhekisela ezithathelwanayo isifo yegciwane ukonakala. Ukuze lesi sifo umvini engozini enkulu kakhulu (leaf elendlalekile, korotkouzlie viral, ukufa simila). Ezihlabayo wadalula chlorosis igciwane, abe phuzi lemon. Ngemithambo amahlamvu, njengoba kuqhathaniswa chlorosis evamile, ezishintshe umbala. Lapho interstices korotkouzliya usayizi is kakhulu ziyancipha, kushiya zincipha, kakhulu ukwakheka anda laterals. Lapho KaMose amaqabunga mvini, ezishintshe umbala ne emithanjeni, futhi oluhlehlela ukugoqa (ezisontekile).

Izinyathelo zokulawula, zokuvimbela

Elinegciwane isitshalo ngokushesha lisishulwe, inhlabathi dichloroethane ezihlalayo (izinsalela). Ukuvimbela ukuvela nokwanda chlorosis kuyinto ezikhethwe ngokucophelela zokutshala impahla (imivini, okuyinto kuhlelwe ukuba itshalwe esikhathini esizayo, Bavunwa ezihlabayo enempilo ngokuphelele futhi eqinile). Ukukhetha ibhukhumaka ezivini izindawo khulula nematodes, okuyizinto abathwali eyinhloko igciwane. Izindawo lapho ngaphambilini amacala isibhadalala igciwane izifo, kutuswa ukuhlwanyela okusanhlamvu (kuze iminyaka eyisithupha ilandelana) ukuthi nematodes ungadli.

Chlorosis evamile (non-esithathelanayo)

It ahluke kancane ezifweni. Nalapha futhi kukhona yellowing amaqabunga, kodwa emithanjeni ahlale green. Ukwanda Imininingwane zalesi sihlahla kakhulu engasenamahloni ngesikhathi esifanayo, kukhona izithombo ngempela obuningi (ikakhulukazi - engxenyeni engezansi ehlathini). Imbangela chlorosis non-ezithathelwanayo ku obonakele isitshalo umzimba elihlobene ne umswakama okweqile, inala lime, ane-alikhali ukuphendula zenhlabathi, kodwa kaningi - ukuntuleka yensimbi.

Izinyathelo zokulawula, zokuvimbela

Lapho ngokweqile lime ekwenziweni ammonium sulfate (3 kg ngaphansi ehlathini amagilebhisi). Kunconywe ukuxhumelela rootstocks amelana lime inhlabathi (wazibonakalisa kakhulu 41-B Chasselas ku Berlandieri). Nge umswakama ngokweqile zingalawulwa ngu yokumba ejulile (ngokushesha ahwamukayo amanzi angadingeki). Uma endaweni yakini imvula yanda, ekuqaleni funa izinhlobo ukuthi amelana chlorosis.

Ngaphezu kwalokho Kunconywa:

- ukwethulwa ekwindla sulfate enhlabathini (kwesokudla ngaphansi kwesihlahla, 500 amagremu);

- sishaye sulphate (0.5%) entwasahlobo, e yokukhula (esikhundleni sulfate ingasetshenziswa yensimbi chelator, okuyinto ingcono nakakhulu);

- ukufakwa ukuvundiswa eziyinkimbinkimbi (micro- futhi macro-) ne-manganese, insimbi, zinc.
