Udzu ndi zotsalira za mbewu zomwe zimatsalira mbewu zikakololedwa, monga chimanga, nyemba, mbatata, mbewu zamafuta, hemp, ndi mapesi a mbewu zina monga thonje, nzimbe, ndi fodya.
dziko langa lili ndi udzu wambiri komanso kufalikira kwakukulu.Pa nthawiyi, kagwiridwe kake kamakhala kokhazikika m’mbali zinayi: chakudya cha ziweto;mafakitale zopangira;zipangizo zamagetsi;magwero a feteleza.Malinga ndi ziwerengero, pafupifupi 35% ya udzu wa mbewu m'dziko langa umagwiritsidwa ntchito ngati mphamvu zakumidzi, 25% imagwiritsidwa ntchito ngati chakudya cha ziweto, 9.81% yokha imabwerera m'minda ngati feteleza, 7% ndi mafakitale, ndipo 20.7% imatayidwa. ndi kutenthedwa.Kuchuluka kwa tirigu, chimanga ndi mapesi ena amawotchedwa m'minda, kutulutsa utsi wambiri wakuda, womwe sunangokhala vuto la botolo m'madera akumidzi kutetezedwa kwa chilengedwe, koma ngakhale chiwopsezo chachikulu m'madera akumidzi.Malinga ndi ziwerengero zoyenera, dziko langa, monga dziko lalikulu laulimi, likhoza kupanga matani oposa 700 miliyoni a udzu chaka chilichonse, zomwe zakhala "zinyalala" zomwe "zimagwiritsidwa ntchito pang'ono" koma ziyenera kutayidwa.Pankhaniyi, imayendetsedwa kwathunthu ndi alimi, ndipo kuchuluka kwa kutentha kwachitika.Zotani pa izi?M'malo mwake, chinsinsi cha vutoli ndikuwongolera kukula ndi kagwiritsidwe ntchito ka udzu wa mbewu ndi kuchuluka kwa kagwiritsidwe ntchito kake.Khoka la udzu lingathandize alimi kuthetsa vutoli.
Udzubale netamapangidwa makamaka ndi polyethylene yatsopano monga chopangira chachikulu, ndipo amapangidwa kudzera munjira zingapo monga kujambula, kuluka, ndi kugudubuza.Amagwiritsidwa ntchito makamaka m'minda, minda ya tirigu ndi malo ena.Kuthandiza kusonkhanitsa msipu, udzu, ndi zina zotero. Kugwiritsa ntchito khoka kumachepetsa kuipitsidwa ndi kutentha kwa udzu ndi udzu, kuteteza chilengedwe, kukhala ndi mpweya wochepa komanso kusamala zachilengedwe.Ukonde wa udzu, kuchuluka kwa singano ndi singano imodzi, nthawi zambiri yoyera kapena yowonekera, pali mizere yodziwika bwino, m'lifupi mwake ndi 1-1.7 metres, nthawi zambiri m'mipukutu, kutalika kwa mpukutu umodzi ndi 2000 mpaka 3600 metres, etc. akhoza kusinthidwa malinga ndi zofunikira.Zonyamula maukonde.Ukonde wowotchera udzu umagwiritsidwa ntchito makamaka pomanga udzu ndi msipu, ndipo kugwiritsa ntchito ukonde wowotchera udzu kumapangitsa kuti ntchitoyo ikhale yabwino kwambiri.
Munthawi yabwinobwino, balere ya udzu imangodzaza mabwalo 2-3, ndipo ekala imodzi ya nthaka imatha kudzaza ndi bale imodzi ya udzu.Ngati udzu umakonzedwa pamanja, zitenga nthawi yochulukirapo kuposa wowolera.M’kanthawi kochepa, minda ya tiriguyo inadzala ndi udzu, ndipo kenako inakhala yaudongo ndi yadongosolo.
