Dothi losakanikira lingafunike ntchito zambiri za mandimu
Monga zinthu zambiri m'chilengedwe, dothi lothandizira udzu (wotchedwa turfgrass ) ayenera kukhala woyenera. Pankhaniyi, muyeso ndi mlingo wa pH kapena acidity. Ngati dothi lanu liri lochepa kwambiri pa pH, kuonjezera laimu kungathandize kubwezeretsa bwino ndi kulimbikitsa udzu wathanzi. Kuzindikira mwamsanga zazing'ono za pH, momwe mungayesetse nthaka yanu ndi nthawi komanso momwe mungagwiritsire ntchito laimu ndi zonse zomwe mukufuna kuti muyambe.
N'chifukwa Chiyani Mukugwiritsa Ntchito Limu?
Kuwonjezera laimu ndi njira yowonjezera yosinthira pH ya nthaka. Nthaka ya pH ndiyeso ya nthaka yokhala ndi dothi kapena acidity. PH ya 7.0 salowerera ndale. Chilichonse pansi pa 7.0 ndi chosavuta, ndipo chirichonse pamwambapa ndi zamchere. Mitengo yambiri imakula bwino ndi pH ya 5.5 mpaka 6.5. Ngati kuyesa kwa nthaka kuchepa kusiyana ndi 5.5, zikhoza kupindula ndi zina zowonjezera.
Dothi lingakhale lachilengedwe lokhazikika koma limatha kuwonjezereka panthawi yake ndi leaching yachilengedwe, kugwiritsa ntchito feteleza wina wa nayitrogeni , mvula yambiri kapena ulimi wothirira madzi, ndi madzi amchere. Low pH imakhudza ntchito ya tizilombo toyambitsa matenda m'nthaka, zomwe zimachititsa kuti udzu ndi zomera zina zisachepera. Chotsatira chake, kuyambira kumachepetsa. Zizindikiro zochepa za pH zochepa zimaphatikizapo kutayika kwa mtundu, kuchepa mphamvu ndi kuchepa mphamvu zowonjezera kutentha ndi kutentha kwa chilala .
Mitundu ya laimu
Limu limene mumagwiritsa ntchito ku udzu ndi chimwala kapena choko. Chigawo chachikulu ndi calcium carbonate. Pali mitundu yambiri ya laimu , ndipo mayeso abwino a nthaka ayenera kukuuzani mtundu wa laimu womwe mukufunikira.
Mtedza wokhala ndi calcium wambiri umatchedwa calcitic laimu ndipo uli ndi phindu lowonjezera calcium kunthaka. Mwala wamakina uli ndi magnesium wambiri ndipo umatchedwa laodomitic laimu. Lamulo la Dolomitic limapanga magnesium ku nthaka ndipo lingagwiritsidwe ntchito ngati mayesero a nthaka amasonyeza kusowa kwa magnesiamu.
Mitundu yambiri ya laimu ingagwiritsidwe ntchito ndi kufalikira kwa udzu wamba.
Mmene Mungayesetse Udothi Wanu
Mukhoza kugula kitsulo ka nthaka pa malo osungirako zamasamba ndi masitolo. Chida chabwino chimawononga madola 15 mpaka $ 20 ndikuyesera pH komanso zakudya monga nitrogen ndi phosphorous. Kulondola kwa zotsatira ndi kovuta kufotokozera, ndipo chidziwitso sichingakuuzeni kuchuluka kwa udzu wanu womwe ukusowa. Kwa ndalama zofanana (ndi nthawi yochulukirapo, mwinamwake masabata awiri kapena atatu), mutha kuyesa nthaka yanu ku utumiki wowonjezerako. Yambiri yunivesite ikuwonjezera nthaka yoyesera pafupifupi $ 10 mpaka $ 20 ndipo kawirikawiri imapereka tsatanetsatane wowonjezera za momwe nthaka yanu ikuyendera ndi pH mlingo.
Tsatirani malangizo othandizira kuti mutenge nyemba. Kawirikawiri ndi bwino kusonkhanitsa zitsulo kuchokera ku dothi lalikulu lalikulu ndikusakaniza zitsanzo pa dera lililonse musanayambe kuziyika. Onetsetsani kuti woyesayo azindikire kuti mukufuna kuphunzira za kuchepetsa udzu wanu. Adzachita yesampula ya SMP pazitsanzo zanu kuti asonyeze kuchuluka kwa laimu.
Nthawi yolemba Lime
Limu lingagwiritsidwe ntchito pa udzu nthawi iliyonse ya chaka kuti dothi silinatenthe, koma limakhala likuchitika nthawi ya masika kapena kugwa. Ndibwino kugwiritsa ntchito laimu pambuyo pochepetsera udzu.
Izi zimathandiza kupatsa komanso zimalola kuti laimu lifike mozama mu nthaka.
