Cyperus rotundus amakonda kumera m'nthaka yotayirira, ndipo kupezeka kwa dothi lamchenga kumakhala kowopsa.Makamaka m’madera a chimanga ndi nzimbe, Cyperus rotundus ndi yovuta kwambiri kulamulira.

Nthawi zambiri zimakhala kagulu kakang'ono kapena kusakanikirana ndi zomera zina kuti zipikisane ndi ulemerero, madzi, ndi feteleza, zomwe zimapangitsa kuti zomera zina zisamakule bwino.Ndilonso gulu la zomera zoyera kumbuyo, nsikidzi zakuda zonunkha, chitsulo ndi tizilombo tina.Ndi udzu woopsa kwambiri padziko lonse lapansi.

Chifukwa cha mizu yapadera ya tuber ya Cyperus rotundus, chinsinsi cha kupalira ndikupha mizu.

Njira zowongolera mankhwala:

1. Chimanga

Benazone - Amagwiritsidwa ntchito pamene chimanga 4-6 chimasiya, mankhwalawa amagwira ntchito bwino pamene kutentha kuli kwakukulu, koma zotsatira zake zimakhala zoipa pamene kutentha kuli kochepa.Amagwiritsidwa ntchito mosamala mumvula yambiri kapena zaka zouma.Benzopine ndi yabwino kwa mbewu yotsatira.

Chlorpyrisulfuron - Mankhwalawa amagwiritsidwa ntchito pambuyo pa masamba 3-5 a chimanga.Zimakhudza kwambiri udzu ndi udzu, ndipo zimakhala zozama, koma liwiro la udzu umene ukumwalira limakhala lochedwa.Nthawi zambiri zimatenga theka la mwezi kuti afe ndi udzu.Ndizosavomerezeka komanso zothandiza Fast dimethyl tetrachloride ndi ntchito zina zosakanikirana, kuti zisapangitse kutsutsa.

Glyphosate - Pambuyo 10 masamba a chimanga, pamene oposa theka la mita, mungagwiritse ntchito glyphosate (glyphosate popanda zosakaniza zina) kupopera namsongole ndi madzi, tcherani khutu kutsitsi malangizo, musati kupopera pa chimanga, mfundo kupalira ndi gwiritsani ntchito udzu Ndi kusiyana kwa malo pakati pa mbewu.

2. Munda wa zipatso

Olima zipatso nthawi zambiri amalimbikitsa kugwiritsa ntchito dimethyl•metazone, glyphosate, ndi glufosinate popopera mankhwala molunjika, ndipo samalani kuti musapozere pamitengo yazipatso.

Ngati mukunena kuti gawo lanu limodzi mwa magawo atatu a ekala likhoza kukumbidwa pamanja, mutha kuchotsa kwathunthu Radix Aconiti mu 2 mpaka 3 zaka.

Lumikizanani nafe kudzera pa imelo ndi foni kuti mumve zambiri komanso mawu
