Ogorodniki, kukula nkhaka mu greenhouses, nthawi zambiri amakumana kuti masamba a zomera kutembenukira chikasu. Zifukwa za zochitika izi ndi zosiyana: kuchokera ku kuphwanya kukula kwa zikhalidwe mpaka matenda a nkhaka. Tiyeni tiganizire za zomwe tingachite ngati masamba a nkhaka mu wowonjezera kutentha amatembenukira chikasu.
Chiwawa cha kulima nkhaka
Aliyense amadziwa kuti nkhaka zimakonda kwambiri chinyezi ndi kutentha. Komabe, m'nyengo yachisanu, chimfine chimayamba, pamene kutentha kumalowa kumakhala pansi pamalo ovomerezeka + 14 ° C. Pankhaniyi, nkhaka mbande zimatha kutembenukira chikasu ndipo kukula kumasiya, ndipo pamatentha pansi pa 0 ° C - ndikumwalira kwathunthu.
Pofuna kuthandiza nkhaka kupulumuka chimfine chotenthachi, m'pofunika kupanga zowonjezerapo zokhala m'mindayo mothandizidwa ndi zipangizo zapadera zojambula.
Chifukwa china chimene masamba a nkhaka mu wowonjezera kutentha amatembenukira chikasu, pangakhale kusowa kwa nthaka m'nthaka ya mchere, makamaka nitrogen. Pankhaniyi, masamba amayamba kutembenukira chikasu, kenako ntchentche, ndipo zipatso zokha zimakhala zofanana. Pofuna kupewa izi, zimatsatira mbande, musanazilemo mu wowonjezera kutentha, manyowa feteleza ndi zofunikira zowonongeka.
Kuda chikasu cha nkhaka kumachitika chifukwa chosakwanira madzi okwanira. Ngati madzi ozizira amagwiritsiridwa ntchito kuti awononge nthaka pansi pa nkhaka, ndiye kuti zomera sizizikonda, ndipo zimakhala zachikasu. Choncho, m'pofunika nthawi zonse kuthirira nkhaka mu wowonjezera kutentha ndi madzi ofunda ndipo makamaka ndi kuyima madzi.
Nkhaka matenda, imene masamba kutembenukira chikasu
Kawirikawiri, nkhaka imakhudzidwa ndi matenda a fungalosis, monga fusariosis. Pankhaniyi, panthawi yomwe mazira amaonekera, masamba amayamba kutembenukira chikasu, ndipo kenako zomera zimatha. Powdery mildew ndi matenda a fungal, omwe masamba a nkhaka amatembenukira ma chikasu. Pofuna kuti matendawa asakhudze kutentha kwa mitengo ya nkhaka, m'pofunika kuchitira nthaka musanadzale potaziyamu permanganate, kapena kugwiritsanso ntchito mankhwala osokoneza bongo, komanso kuwonjezera mitundu yosiyanasiyana ya nkhaka zomwe zimagonjetsedwa ndi matendawa.
Nkhaka zingakhudzidwe nthawi yonse ndi nsabwe za m'masamba ndi kangaude mite. Ndibwino kuti mumenyane nawo ndi mankhwala monga Akarin, Tsymbush, Fitoverm ndi ena.
