Leaf chlorosis: description, photos, kula da hanyoyin

Duk wani lambu fuskantar wani lokaci kamar ganye chlorosis. Shuka cutar bayyana kanta a wani m (-season) yellowing da ganye fall. Hanyar cutar ta'allaka da take hakkin chlorophyll samuwar, don haka - rage aiki na photosynthesis. Bar haka na iya rasa launi, ba kawai gaba daya amma kuma partially da sabon (matasa) harbe da kuma ganye suna ƙunci kula. A gefuna da ganye ruwa ne sau da yawa juya, kafa buds (a launuka) ne maras kyau. harba tukwici suke ko dai sosai rauni ko shrunken.

Leaf chlorosis iya zama dauke da kwayar cutar (yiwu samu daga sauran shuke-shuke) da kuma maras dauke da kwayar cutar (daga keta noma ayyuka). La'akari da chlorosis daki-daki.

Don fara da - leaf chlorosis (Photo kamu da shuke-shuke), inda, a matsayin misali - inabõbi:

Kamuwa chlorosis na innabi ganye

Lambu kira shi "leaf blotch" da "yellow mosaic". Yana nufin wani dauke da kwayar cutar kwayar cuta daga degeneration. Domin inabi cuta ne mai matukar tsanani hadari (leaf mirgina, kwayar korotkouzlie, da mutuwa da shuka). Bushes fallasa chlorosis cutar, zama rawaya lemun tsami. A jijiyoyinmu daga ganye, kamar yadda tsayayya ga saba chlorosis, discolored. Lokacin da korotkouzliya interstices size aka rage muhimmanci, ganye ƙunci, muhimmanci ƙara samuwar laterals. Lokacin da mosaic inabi ganye, discolored tare da veins, da kuma ji ƙyama kunsa (Twisted).

Kamuwa shuka nan da nan tumɓukakku ne, kasar gona ne etched dichloroethane (sharan). Hana fitowan kuma yaduwan chlorosis ne a mai da hankali selection na dasa kayan (inabõbi, wanda aka shirya za a shuka a nan gaba, an girbe daga bushes gaba daya lafiya kuma karfi). Don zaɓi alamar shafi na gonakin inabi yankunan free of nematodes, wanda su ne babban dako da cutar.

Chlorosis al'ada (maras dauke da kwayar cutar)

Ya bambanta da ɗan daga kamuwa da cuta. A nan ma akwai yellowing da ganye, amma jijiyoyinmu zama kore.

Lokacin da wani wuce haddi na lemun tsami yin ammonium sulfate (3 kg karkashin daji inabi). Nagari grafting rootstocks resistant zuwa lemun tsami ƙasa (mafi tabbatar 41-B Chasselas a kan Berlandieri). Tare da wuce haddi danshi za a iya sarrafawa da zurfin digging (sauri evaporating wuce haddi ruwa). Idan ka yanki na ƙara ruwan sama, asalin nemi iri da suke resistant zuwa chlorosis.

Bugu da shawarar:

- gabatarwar kaka sulfate a cikin ƙasa (dama karkashin daji, 500 grams).

- spraying sulphate (0.5%) a cikin spring, a cikin girma kakar (maimakon sulfate za a iya amfani da baƙin ƙarfe chelator, wanda shi ne ma mafi alhẽri).
