Kodi muyenera kuwonjezera feteleza kangati pamunda wanu?

KangatiudzuKufunika kwa kuvala pamwamba kumadalira mtundu wa dothi lomwe lili kale pansi pa udzu. Makalabu ena a gofu amasinthidwa pamwamba kobiriwira milungu iwiri iliyonse, koma musadandaule: kunyumba, ngakhale kwa anthu omwe ali ndi dothi loipa kwambiri, kamodzi pachaka ndikokwanira.

Manyowa osakaniza a nayitrogeni, phosphorous, ndi potaziyamu ayenera kuyikidwa nthawi yolima. Nthawi zambiri amayikidwa mutadula mitengo komanso musanathirire madzi. Manyowa oyambira makamaka ndi feteleza wachilengedwe, womwe uyenera kusungunuka kwathunthu. Kuchuluka kwa feteleza woyambira womwe umagwiritsidwa ntchito pa hekitala kuyenera kukhala matani 75-110, ndipo superphosphate iyenera kukhala 300-750kg, yomwe ingaphatikizidwe ndi kulima nthaka kuti igwiritse ntchito feteleza.

Chiŵerengero cha nayitrogeni:phosphorous:potassium chiyenera kulamulidwa pa 5:4:3. Kuchuluka kwa feteleza kumakhala kopepuka komanso kocheperako mu nthawi yophukira, ndipo nthawi yophukira imakhala yolimba kuposa nthawi yophukira, zomwe zingawonjezere feteleza wowonjezera mizu. Feteleza ndi kuthirira ziyenera kugwirizanitsidwa bwino kuti zisawononge udzu chifukwa chogwiritsa ntchito molakwika. Kugwiritsa ntchito feteleza wachilengedwe sikungongowonjezera thanzi la nthaka, komanso kumawonjezera kutseguka kwa nthaka ndi kulowa kwa nthaka, komanso kumathandizanso udzu kuti upulumuke m'nyengo yozizira bwino.

Udzu wa turf kumpoto ndi woyenera kufesedwa kawiri pachaka, kumayambiriro kwa masika ndi kumayambiriro kwa nthawi yophukira. Udzu woyamba kufesedwa kumayambiriro kwa mwezi wa Epulo (udzu woyenera) sungopanga udzu wokha. sinthani kukhala wobiriwira pasadakhale, komanso thandizani nyengo yoziziraudzu wa turfgrasskuti mubwezeretse zowonongeka ndikulimbitsa udzu usanamere udzu wapachaka; chita feteleza wachiwiri mu Seputembala. Kuwonjezera pa kukulitsa nthawi yobiriwira mpaka kumapeto kwa nthawi yophukira ndi yozizira, ingathandizenso kukula kwa nthambi zatsopano ndi mizu chaka chachiwiri.

Kuti malo ake akhale abwino, obiriwira nthawi yayitali, komanso opirira matenda ndi tizilombo toononga, payenera kukhala zakudya zina. Chifukwa chake, ndikofunikira kulimbitsa mizu yowonjezera ndi kuwonjezera zinthu zina kupatula N, P, ndi K kuti ikwaniritse zosowa za kukula kwake.

Mu kasamalidwe ka zinthu zosamalira, cholinga chachikulu chimakhala pa kasamalidwe ka madzi ndi feteleza, kumamatira masika kuti asawononge madontho, kumamatira ku dzuwa nthawi yachilimwe, nthawi yophukira ndi yozizira kumamatira ku udzu kuti usawononge mphepo ndi chinyezi. Nthawi zambiri, thirani madzi kamodzi m'mawa ndi madzulo mkati mwa sabata imodzi mutathira udzu, ndipo yang'anani ngati udzu waphwanyika, ndipo mizu ya udzu imafunika kukhala pafupi ndi nthaka ya alendo. Thirani madzi kamodzi patsiku madzulo mkati mwa milungu iwiri mutathira. Pambuyo pa milungu iwiri, kutengera nyengo ndi nyengo, nthawi zambiri zimatenga masiku awiri kapena atatu kuti muthire madzi, makamaka kupatsa chinyezi.

Feteleza patatha sabata imodzi mutabzala mpaka miyezi itatu, perekani feteleza kamodzi pa theka lililonse la mwezi, thirani ndi yankho la urea la 0.1% ~ 0.3% pamodzi ndi kuthirira, chepetsani udzu musanabzale ndi wandiweyani; kamodzi pamwezi, 667m urea 2 ~ 3kg, tsiku lamvula Gwiritsani ntchito chochekera udzu kudula udzu pamene udzu wonse uli ndi kutalika kwa 8 ~ 10cm pofalitsa kapena kuthira madzi munyengo yoyera.

Udzu umachotsedwa patatha theka la mwezi mutabzala, ndipo kumapeto kwa Januwale, udzu umayamba kukula. Udzu uyenera kukumba ndi kuzika mizu nthawi yake, ndikuumanga pambuyo pokumba kuti usakhudze kukula kwa udzu waukulu. Udzu watsopano womwe wabzalidwa nthawi zambiri umakhala wopanda tizilombo ndi matenda, ndipo sufunika kupopera. Kuti ukule mwachangu, 0.1% mpaka 0.5% ya potassium dihydrogen phosphate ikhoza kupopera pamodzi ndi kuthirira pambuyo pake.
