Ciderates amatchedwa zomera zoumba, zomwe zimapindulitsa ndi nthaka ya nayitrogeni, zimapangidwanso bwino ndipo zimawongolera kukula kwa udzu. Izi zimapangitsa kuti feteleza zamagetsi zisagwiritsidwe ntchito kuti zithetse nthaka yosauka. Mitengo yamakono , makamaka kumayambiriro kwa masika, musanadzalemo mbewu zazikulu, kapena kugwa. Pachifukwachi, amaluwa ambiri amakayikira ngati kuli koyenera kukumba pambali pa nyengo yozizira. Tiyeni tiwone izo.
Kodi ndikofunikira kukumba kumbali yachisanu?
Monga mukudziwira, nayitrogeni imakwera pamwamba ndi rootlets ya zomera - imayang'ana. Izi zikuphatikizapo mpiru, oats, nandolo, rapesed, clover, alfalfa ndi ena ambiri. Zinthu zowonongeka pamwamba pa nsongazo zimalowetsa nthaka yomwe yatha, ndipo mzukulu wapadera umapangitsa dothi kutsegulidwa. Kawirikawiri alimi amasankha "kudyetsa" nthaka mutatha kukolola, kumapeto kwa chilimwe kapena m'mawa. Koma nthawi imadutsa, ndipo pamene chimfine chimayandikira, eni eni akewo amakhala ndi funso loti asasokoneze. Ndipotu, pali malingaliro ambiri:
- Ambiri amakhulupirira kuti kukumba n'kofunika kuti chomera chifike pamtunda. Pambuyo pa kuwonongeka kwa zomera, zinthu zothandiza zimatha kugwera m'nthaka, zikukhuta. Ndipo izi ndi zolondola, ngati tikulankhula za ngati mukufuna kukumba mpiru kapena chikhalidwe china chilichonse chokhalira pansi.
- Koma, panthawi imodzimodziyo, pamene akumba, pali kusintha kwa dziko lapansi, chifukwa chomwe umphumphu wa mizu ya m'mbuyo umasokonezeka. Chifukwa chake, nayitrogeni ndi zinthu zamtengo wapatali zomwe zimapezeka mumzuwo sizikhala mu nthaka, koma zimakhala zowonongeka.
Ndiye chochita chiyani ngati pali kutsutsana kotero ngati mukufunika kukumba nthaka mutatha kudutsa?
Kugwiritsira ntchito flatbed kukumba
Alimi ogwira ntchito alangizi amalimbikitsa kugwiritsa ntchito zosangalatsa horticultural chida - planar . Ndi nsalu yamatabwa, pamapeto pake, pogwiritsa ntchito ziboliboli, chitsulo chosungunula chokhala ndi zitsulo ndi chokhazikika. Komanso, malo atatuwa akuwongolera kwambiri. Mbalameyo imakulolani kuti muzitha kuchitira nthaka mosamala, osati fosholo kapena khasu. Pa nthawi yomweyo kumasula ndi kukumba dothi ndi chodula chapamwamba chimapezeka popanda kusintha nthaka mozama masentimita 5-7. Pa nthawi yomweyi, masamba a zidutswa zimagwa pansi. Chinthu chachikulu ndicho kuchita izi musanafike pamene nsonga zikukula pamwamba pa 10-15 masentimita mu msinkhu. Ndiyetu yankho loyenera kuganiza ngati mukufuna kukumba, kunena, oats kapena rye ngati mchenga kugwa.
