Kodi muyenera kuwonjezera feteleza kangati ku udzu wanu?

Nthawi zambirimalamuloImasowa pakulupa kwambiri zimatengera mtundu wa dothi lomwe lilipo kale pansi pa udzu. Ziphuphu zina za gofu zimasintha kwambiri masabata awiri aliwonse, koma osadandaula: kunyumba, ngakhale kwa anthu omwe ali ndi dothi loyipitsitsa lomwe tili nalo, kamodzi pachaka ndichokwanira.

Nitrogen, phosphorous, ndi potaziyamu glayiar yothina ma granalar ayenera kugwiritsidwa ntchito munthawi yakula. Nthawi zambiri zimagwiritsidwa ntchito mutadulira ndipo musanadyeze kuthirira. Feteleza wapansi amakhala makamaka feteleza wachilengedwe, womwe uyenera kuwongoleredwa kwathunthu. Kuchuluka kwa feteleza woyambira pa heckitare pa uyenera kukhala matani 75-110, ndipo superphosphate iyenera kukhala 300-750kg iyenera kukhala 300-750kg iyenera kukhala 300-750kg iyenera kukhala 300-750kg, yomwe imatha kuphatikizidwa ndi nthaka yolima kuti mugwiritse ntchito feteleza.

Chiwerengero cha nayitrogeni: phosphorous: Potaziyamu ayenera kuwongoleredwa pa 5: 4: 3. Mulingo wogwiritsa ntchito ndi wowonda komanso wowonda mu nthawi yotukuka, ndipo nthawi yocheperako imalimba kuposa nthawi yotukuka, yomwe imatha kuwonjezera umuna wowonjezerapo. Umuna ndi kuthirira ziyenera kuyang'aniridwa kwambiri kuti zisawonongeke ndi udzu woyambitsidwa ndi kugwiritsa ntchito molakwika. Kugwiritsa ntchito feteleza wachilengedwe sikungangokulitsa zakudya za dothi, komanso kukonzanso kuda nkhawa komanso kuperewera, komanso kumathandizanso malo kuti apulumuke nthawi yachisanu.

Kutumphuna kumpoto kuli koyenera kuphatikizidwa kawiri pachaka, koyambirira kwa kasupe ndi koyambirira kwa nyundo. Umuna woyamba kumayambiriro kwa Epulo (umuna woyenera) sangangopanga udzu Sinthani zobiriwira pasadakhale, komanso thandizani nyengo yabwinokachikaKubwezeretsa kuwonongeka ndikukulitsa turf chisanafike mphutsi za pamphuno; Chitani umuna wachiwiri mu Seputembala. Kuphatikiza pa kutha kwa nthawi yobiriwira mpaka nthawi yophukira komanso nthawi yozizira, imathanso kulimbikitsa kukula kwa nthambi za nthambi zatsopano ndi ma rhizomes mchaka chachiwiri.

Pofuna kukhalabe ndi malo abwino, zobiriwira zazitali, komanso kukana matenda amphamvu ndi tizirombo, tizilombo toudction, kuperewera kwa zakudya kumayenera kusungidwa. Chifukwa chake, ndikofunikira kulimbitsa zowonjezera muzu zowonjezera ndi zinthu zina kupatula n, p, ndi k, ndi k, ndi k, ndi k, ndi k, ndi k, ndi k, ndi K kuti mukwaniritse zosowa zake.

Mukuyang'anira, kutsindika kuli pamadzi ndi feteleza amayendetsa kuti ateteze madola, chilimwe komanso nthawi yozizira kumamatira ku udzu kuti chichepetse mphepo ndi kunyowa. Nthawi zambiri, utsi wa madzi m'mawa ndi madzulo mkati mwa sabata limodzi mutatha udzu, ndikuwona ngati Turf imaphatikizidwa, ndipo mizu ya udzu imayenera kukhala pafupi ndi alendo. Utsi madzi kamodzi patsiku madzulo mkati mwa masabata awiri mutatha kugwiritsa ntchito. Pambuyo pa masabata awiri, kutengera nyengo ndi nyengo, zimatenga masiku awiri mpaka atatu kuti utsi utsi, makamaka kunyowa.

Manyowa sabata 1 mutabzala mpaka miyezi itatu, manyowa kamodzi pa mwezi, utsi ndi 0,1% ~ 0.3% urea urea yankho lophatikizidwa ndi kuthirira; Kamodzi pamwezi, 667m urea 2 ~ 3kg, tsiku lamvula kugwiritsa ntchito udzu kuti udzure udzu pomwe udzu wonse ndi 8 ~ 10cm kukwera pomwe nyengo yofalitsidwa ndi madzi.

Namsongole amachotsedwa koyambirira kwa mwezi umodzi atabzala, ndipo mochedwa ngati Januware, namsongole amayamba kukula. Namsongole ayenera kukumbidwa ndipo atazika mizu, ophatikizidwa atakumba kuti asakhudze udzu waukulu. Dzala litabzala bwino nthawi zambiri limakhala lopanda tizirombo ndi matenda, ndipo sizifunikira kuthiridwa. Pofuna kuwonjezera kukula, 0.1% mpaka 0,5% potaziyamu diIhphaten phosphate amatha kuthiridwa ndi kuthirira pambuyo pake.
