I-chlorosis yamacembe: inkcazo, ifoto, iindlela zokulwa

Naluphi na umyezo wegadi ujongana nale ngcamango njengechlorosis yamagqabi. Isifo sesityalo sibonakaliswe ngokungavumelekanga (ngaphandle kwexesha) ukutshatyalaliswa kwamagqabi kunye nokuwa. Isizathu sesi sifo sisekuphula umthetho we-chlorophyll, kwaye ngenxa yoko-ukwehla komsebenzi we-photosynthesis. Amagqabha angakwazi ukulahlekelwa ngumbala wabo kuphela, kodwa nakwincinane, kwaye amatsha (amancinci) atshabalale kunye namacembe amancinci. Amaphethelo amaqabunga amaqabunga ahlala ephihliwe, amaqabunga aphethwe (kwiintyatyambo) aphelile. Iingcebiso zamahlumela zibuthakathaka okanye zidibene.

I-chlorosis yamagqabi anokusasazeka (mhlawumbi ukuchaphazela ezinye izityalo) kunye nokungenasifo (okwenzekayo xa izenzo zokulima ziphulwa). Cinga i-chlorosis ngokubanzi.

Ukuqala kwe-chlorosis yamagqabi (iifoto zezityalo ezithelelekileyo), apho, umzekelo, iidiya zamagilebhisi:

I-chlorosis echaphazelekayo yomdiliya ishiya

Abagadi beligadi bawubiza ngokuthi "amaqabunga athatywayo" kunye "nombala ophuzi". Ukubhekisele kwizifo zentsholongwane zentsholongwane ezithintekayo. Ngenxa yomdiliya, isifo sibonisa ingozi enkulu (i-leaf twisting, virus-short-stemming, ukufa kwesityalo). Iibhasi ezityhila kwi-chlorosis yintsholongwane ziba li-yellow lemon. Amaqabunga amaqabunga, ngokungafani ne-chlorosis eqhelekileyo, i-discolor. Ngefostile elifutshane, ubukhulu be-internodes buyancipha ngokukhawuleza, ukushiya ukuncipha, ukusekwa kwamanyathelo okunyuka kakhulu. Xa ama-mosaic ashiya amagilebhisi, adibanisa kunye nemithanjeni, ebomvu kwaye ehlanganiswe (ephihliweyo).

Amanyathelo okulawula, ukukhusela

Isityalo esithelelekileyo sisuswa ngokukhawuleza, umhlaba utyunjwe ne-dichloroethane (iisubhu zerube). Ukuthintela ukuvela nokusabalala kwe-chlorosis, ukukhetha ngokucophelela kokutyala impahla (umdiliya, ocetywayo ukutyalwa kwixesha elizayo, uvunwa kwiindawo ezinomsoco kwaye unamandla). Ukubhenkca izidiliya, khetha iindawo ezingenakho kwi-neatodes, ezona ziyi-vectors eziphambili zegciwane. Amasayithi awayebhaliweyo amaxesha okugqabhuka kwezifo ezinjengegciwane-ntsholongwane kucetyiswa ukuba ihlwayelwe ngqolowa (ukufikelela kwiminyaka emithandathu elandelelanayo) apho i-neematodes engayondli.

I-chlorosis evamile (engeyiyo isifo)

Ngokungafani nentsholongwane. Kukho ukwenziwa koqheliso lwamagqabi, kodwa iiswini zihlala ziluhlaza. Ngexesha elifanayo, ukukhula ngokubanzi kwesityalo kuphawulwe ngokukhawuleza, ngexesha elifanayo kukho ukukhula okuninzi (ikakhulukazi - iindawo eziphantsi kwehlathi). Isizathu sokubonakala kwe-chlorosis engasetshenziswanga sisetyenziselwa ukutshatyalaliswa kwesityalo, esinoxinzelelo obuninzi, ubuninzi belime, ukuphendula kwehlabathi, kodwa ngokuphindaphindiweyo ngokungabikho kwesinyithi.

Amanyathelo okulawula, ukukhusela

Ngobuninzi belime, i- ammonium sulphate (3 kg phantsi kwesihlwele seidiliya) iyaziswa. Izitofu zinconywa kwiingcambu ezingagxininisi kumhlaba wokubala (ininzi ephakanyisiwe ngokwayo i-41-B Chasla eBerlandandi). Ngomngcipheko ongaphezulu, unokulwa ngokugqithisa okunzulu (amanzi angaphezu kwamanzi aphuthuma ngokukhawuleza). Ukuba endaweni yakho inani lemvula liphezulu, qaleni ubeke ingqalelo kwiintlobo ezinokungena kwi-chlorosis.

Ukongezwa kunyanzeliswa:

Isicelo sekwindla ye vitriol emhlabathini (ngqo phantsi kwehlathi, ama-gram 500);

- ukufafaza nge-vitriol (0.5%) entwasahlobo, ngexesha lexesha lokukhula (esikhundleni se vitriol, i- chelate yensimbi ingasetyenziselwa , yinto engcono kakhulu);

- ukusungulwa kokutya okunzima (micro-, macro-) kunye nomxholo we-manganese, isinyithi, i-zinc.
