Chifukwa chikasu phwetekere mbande? Ichi ndi chizindikiro kuti chinachake akusowa

A chigawo kiyi wa mbewu iliyonse - chlorophyll. Chifukwa n'kofunika kugwirizana pakati pa dzuwa ndi biosphere: wotchedwa chlorophyll maselo chomera pansi zochita za dzuwa synthesizes kwa madzi ndi mpweya woipa pa nkhani organic. chikasu mbewu n'zomwe kuphwanya maphunziro awo ku wotchedwa chlorophyll - nthenda yotchedwa chlorosis. Choncho yankho la funso la chifukwa mbande chikasu phwetekere ndi wosavuta. Koma izi si zokwanira - tifunika muzu. Ndi ochuluka a iwo.

Ambiri a iwo - kuphwanya mphamvu ya dongosolo mizu. Izi zimachitika chifukwa kuwonongeka, thupi kapena kutentha kwake (subcooling). Koma ngati kusokonezedwa kutentha, chlorosis amakhudza zomera lonse. Ndipo ngati, nkuti, mawotchi kuwonongeka kwa dongosolo muzu kwachititsa ankafika mbande phwetekere mu munda, masamba okhaokha m'munsi kutembenukira wachikasu. Pankhaniyi, muyenera kudikira tichotseretu mbande ndi mizu latsopano adventitious - Tomato chlorosis kupirira paokha.

Kudziwa chifukwa cha chlorosis zokwanira kuyang'anitsitsa pa masamba achinyamata a mbewu. Ndipo ngati chikasu mbande phwetekere ali ndi achikulire (m'munsi) masamba ayenera amaganiziridwa monga kusowa imodzi yofunika kwambiri zinthu phwetekere mankhwala.
Nthawi zambiri chlorosis mbande phwetekere limasonyeza akusowa asafe. Iye analankhula ndi tsamba mitsempha bluish-wofiira mtundu, ndipo masamba ang'ono mu chomera lonse. M'munsi masamba kufa pambuyo chikasu. Ngati mbande mwakula zogulitsa, simungathe ngakhale muyesere kutenga kumsika: zizindikiro bwino chlorosis chiopsyezo makasitomala ake, ndi sitingazilongole chifukwa mbande chikasu tomato, sititenga.

Chikasu akhoza kuyambitsa akusowa potassium ndondomeko pano koma nthawi patali chifukwa kudzikundikira la ammonia ndi asafe pamodzi ndi madzi m'thupi masamba ndi kupotoza awo, kufikira maonekedwe a zizindikiro za minofu necrosis.
Chifukwa china chimene chikasu phwetekere mbande, ndi kuperewera kwa nthaka. Iye amadzionetsa ambiri ndi zazing'ono flecks a mtundu wachikasu masamba achinyamata. Nawonso, abnormally wamng'ono, akhoza kukhala wachikasu kwathunthu, nthawi zina anapotoza m'mwamba. Minofu necrosis, mosiyana akusowa potaziyamu kumaonekera pomwepo kudutsa pamwamba pepala, koma chimafikira ndithu mofulumira.

Ngati chlorosis masamba achinyamata mbande akuyamba ndi zapansi awo, ndi mtundu ranges kuchokera lachikasu wobiriwira mwa ndimu-chikasu kukhala chikasu woyera, mbewu kuyankha chitsulo akusowa. Iwo zimaonekera okha masamba achinyamata, osati kuti akamakula. Mtundu uwu wa akusowa angayambe magawo oyambirira mbande kukula, ngati masana ndi usiku kusonyeza siligwirizana Mavalidwe okhala chitsulo. Munthu akhoza kungowauzira kuyambiranso iwo, ngati chomera abwera zachilendo maola angapo.

Komabe, kuperewera micronutrient ndi zakudya ndi mosavuta kukonza. Ndi ndithu chinthu china pamene yankho ku funso la chifukwa mbande chikasu tomato, adzakhala motere: ndi Fusarium. Yoopsa mafangasi matenda kukantha pa tomato m'badwo uliwonse. Menyani kovuta chifukwa nthendayo wapezeka mochedwa kwambiri. Njira zothandiza kwambiri mufuna fusarium ndi kupewa. Koma ngati mbewu kale kukanthidwa, zomera wathanzi ayenera olekanitsidwa yomweyo kwa anthu odwala; koyamba kuchitira mankhwala, wachiwiri - yomweyo kuwononga (chipsyerere).
