Osati nthawi zina, ndipo chaka ndi chaka kuti asonkhanitse mbewu yabwino ya plums, m'pofunika kusamalira mtengo uwu. Chimodzi mwa mfundo zofunika kwambiri ndi kuyambitsa feteleza. Kodi ndi motani momwe angadyetse maula, kuti apindule bwino, ndipo zipatso sizikugwa, tidzakambirana m'nkhaniyi.
Kodi feteleza amafunikira kusowa?
Sizingatheke kutchula feteleza yabwino kwa zipatso zamwala (apulo, maula, chitumbuwa), kuti abereke zipatso bwino. Ichi ndi chifukwa chakuti akufunikira zonse organic ndi mineral feteleza. Pulasitiki, kukonzekera ndi phosphorous, nayitrogeni ndi potaziyamu ndizofunikira kwambiri. Izi zikuphatikizapo: ammonium nitrate, urea, superphosphate , ammonium sulphate, potaziyamu mchere, komanso phulusa (mitengo ndi mbewu za tirigu). Chinthu chachikulu ndi kuwabweretsa nthawi yomwe mtengowo ukusowa.
Kodi ndi nthawi yanji yomwe mungagwiritsire ntchito fetereza pansi pa madzi?
Kumayambiriro kwa kasupe (makamaka mitengo yaying'ono) m'pofunika kufotokoza nitrogen-feteleza (nitrate kapena urea 20-25 g pa 1 m sup2, ndi ammonium sulphate 60 g pa 1 m sup2) ndi manyowa. Malingana ndi kukula kwa nthaka, feteleza wowonjezera angafunike. Mwachitsanzo: laimu, phulusa kapena laimu-ammonium nitrate ayenera kuwonjezeredwa ku dothi losavuta.
Komanso m'chaka, kuti muwonjezere zokolola, zimalimbikitsa kupopera korona wa mtengo ndi njira ya 0.5% ya urea. Kupaka pamwamba uku kumachitika kangapo ndi nthawi ya masiku 7-10.
Mitengo yowumba kale (zaka zoposa zitatu), m'dzinja, pakukumba nthaka, m'pofunika kupanga potaziyamu (30-45 g pa 1 m & sup2) ndi phosphorous (70 - 80 g pa 1 m & sup2) feteleza. Izi ndi chifukwa chakuti mcherewu ndi ovuta kuthetsa, choncho zimatenga nthawi yambiri kuti imwani zomera zawo.
Manyowa opangidwa ndi feteleza sayenera kulengezedwa chaka chilichonse, koma kamodzi pa zaka 2-3 pa mlingo wa matani 40 pa 1 ha.
