Leaf chlorosis: kufotokoza, photos, kulamulira njira

nyakulima akupezeka ndi liwu monga tsamba chlorosis. matenda chomera kumaonekera mu zobwera (-season) chikasu ndi tsamba kugwa. Chifukwa cha matenda lagona kuphwanya wotchedwa chlorophyll mapangidwe, kotero - kuchepetsa ntchito ya photosynthesis. Masamba Choncho angasiye mtundu, osati kwathunthu komanso pang'ono ndi watsopano (achinyamata) mphukira ndi masamba m'mbuyo chimaonekadi. M'mbali mwa tsamba tsamba kawirikawiri zopotoka masamba anapanga (mu mitundu) ndi opunduka. kuwombera nsonga mwina ofooka kwambiri kapena shrunken.

Leaf chlorosis akhoza kukhala matenda (zotheka kuipitsidwa wa mbewu zina) ndipo si opatsirana (kuchokera kuyan'anila ulimi makhalidwe). Taganizirani chlorosis mwatsatanetsatane.

Kuyamba ndi kuyamba - tsamba chlorosis (Photo zomera matenda), kumene, monga chitsanzo - mipesa:

Matenda chlorosis masamba mphesa

Wamaluwa icho "tsamba chikanga" ndi "chikasu zithunzi". Zimatanthauza matenda opatsirana tizilombo wa alibe. Matenda mpesa ngozi yoopsa kwambiri (tsamba pakubwezeretsa, tizilombo korotkouzlie, imfa ya mbewu). Tchire poyera chlorosis HIV, kukhala chikasu mandimu. Mitsempha ya masamba, monga kuyenera kwa chlorosis mwachizolowezi, discolored. Pamene korotkouzliya interstices kukula kwambiri yafupika, masamba m'mbuyo, kwambiri kuchuluka mapangidwe laterals. Pamene zithunzi masamba mpesa, discolored ndi mitsempha, ndi kuotcha Manga (zopotoka).

Control miyeso, kupewa

Kachilombo zomera yomweyo achotsa, nthaka tikuona dichloroethane (zatsalira). Kuteteza zikamera ndi kufala kwa chlorosis ndi kusankha mosamala kubzala zakuthupi (ziyangoyango zomwe zakonzedwa kuti zibzalidwe m'tsogolo, akusonkhanitsidwa kuchokera tchire kwathunthu athanzi ndi amphamvu). Kuti musankhe Bookmark wa mpesa m'madera ufulu wa nematodes, amene onyamula yaikulu ya HIV. Zina zimene kale olembedwa milandu kubuka matenda HIV, izo tikulimbikitsidwa kufesa mbewu (kwa zaka zisanu ndi chimodzi mu mzere) kuti nematodes musadye.

Chlorosis yachibadwa (si opatsirana)

Kumasiyana penapake ku matenda. Apa kwambiri pali chikasu masamba, koma mitsempha kukhala obiriwira. The kukula kwake kwa zomera kwambiri imathetsa pa nthawi yomweyo, pali mbewu zambiri ndithu (makamaka - mmunsi mwa chitsamba). Chifukwa cha chlorosis si opatsirana ali kagayidwe zowonongeka chomera kugwirizana ndi chinyezi muyeso, zambiri laimu, zamchere zimene nthaka, koma nthawi zambiri - ndi kusowa kwa ayironi.

Control miyeso, kupewa

Pamene owonjezera laimu kupanga sulphate ammonium (3 kg pansi mphesa chitsamba). Analimbikitsa kumezetsanitsa rootstocks kugonjetsedwa ndi laimu dothi (ambiri anasonyeza 41-B Chasselas pa Berlandieri). Ndi chinyezi owonjezera akhoza lizilamuliridwa ndi kukumba kwambiri (mofulumira evaporating madzi owonjezera). Ngati m'dera lanu la mvula yochulukirapo, poyamba kuyang'ana mitundu amene kugonjetsedwa chlorosis.

Komanso tikulimbikitsidwa:

- kumayambiriro yophukira sulphate m'nthaka (ndipo pa chitsamba magalamu 500);

- kupopera sulphate (0.5%) mu kasupe, mu nyengo kukula (m'malo sulphate angagwiritsidwe ntchito chitsulo chelator, umene uli bwino);

- kulolerana zovuta feteleza (micro- ndi macro-) ndi manganese, chitsulo, nthaka.
