(1) Kulimidwa kwa lamba wa soya ndi chimanga

Kum’mwera chakumadzulo kwa China, kuli mvula yambiri, mitundu yambiri ya namsongole, ndipo n’kovuta kuwaletsa.Chimanga chimafesedwa pamaso pa soya, ndipo kugwiritsa ntchito mankhwala ophera udzu kuyenera "kusindikizidwa ndi kuphatikiza".Mukabzala komanso musanamete, nthaka iyenera kusindikizidwa ndi metolachlor (kapena acetochlor)+thiofensulfuron methyl ndi mankhwala ena.Ngati pali udzu m'munda musanafese, m'munda ukhoza kupopera ndi kupopera kwa glyphosate;Ngati kusindikiza kwa nthaka sikuli koyenera ndipo chithandizo cha tsinde ndi masamba chikufunika, nicosulfuron methyl+chlorofluoropyranoxyacetic acid (kapena dichloropyridic acid, methimaxone) angagwiritsidwe ntchito kuwongolera tsinde ndi masamba opopera (m'malo obzala chimanga) chachitatu. mpaka wachisanu tsamba la mbande za chimanga.

Kutatsala masiku atatu kuti soya abzalidwe, kupopera kwa glyphosate kunkachitika m'munda.Mukabzala, mbande zisanabzalidwe, mankhwala ophera tizilombo monga promethazine (kapena acetochlor)+thiophensulfron amasankhidwa kuti atseke nthaka.Ngati nthaka kusindikiza zotsatira si abwino ndipo ayenera kuchitiridwa ndi tsinde ndi tsamba kutsitsi, quinclovir

(2) Kulimidwa kwa lamba wa soya ndi chimanga

Mtsinje wa Yellow River, Huaihai Mtsinje, pakati ndi kumunsi kwa Mtsinje wa Yangtze, ndi kumpoto chakumadzulo, soya ndi chimanga zimafesedwa nthawi imodzi.Kugwiritsa ntchitomankhwala ophera udzu makamaka zochokera nthaka kusindikiza mankhwala pamaso mbande pambuyo kufesa, chimene chiyenera kumalizidwa mkati 2 masiku kufesa.Nthaka imatsekedwa ndi mankhwala monga promethamide (kapena metolachlor, acetochlor)+azosulfochlor (kapena thiophenuron).Pamene dothi la m'munda momwe tirigu wakale watsekedwa ndi mankhwala ophera udzu, ndi bwino kulima mozungulira kuchotsa ziputu, kupanga chinyezi, kenako kubzala ndikuthira mankhwalawo musanabzale;M'minda yachindunji yodzala ndi chiputu cha tirigu, m'pofunika kuonjezera kumwa kwa madzi pa muyeso umodzi, ndipo ngati ziloleza, kuthirira kwanthawi yake kuyenera kuchitika mukatha kugwiritsa ntchito.mankhwala ophera tizilombo;M'madera owuma komanso mphepo yamkuntho monga kumpoto chakumadzulo, ndi bwino kusakaniza dothi mutatha kugwiritsa ntchitomankhwala ophera udzu, ndi madera am'madzi anthawi yake pomwe mikhalidwe imalola.

Ngati kusindikiza kwa dothi sikuli koyenera ndipo kupopera kwa tsinde kukufunika, kutha kugwiritsidwa ntchito pakatha mbande 3-5 pambuyo pa mbande ya chimanga, 2 ~ 3 tsamba la soya, 2 ~ 5 tsamba la udzu. .Malinga ndi udzu wa komweko, nicosulfuron (kapena oxazolone)+bentazone (kapena cloflupyroxyacetic acid) M'munda wa soya, quinoxal (kapena flumetafop-p-ethyl) + dimethasone (kapena ethyl flumetafop-ethyl) amagwiritsidwa ntchito popanga tsinde ndi masamba. Kupalira kotsogola (makatani akuthupi amagwiritsidwa ntchito kulekanitsa chimanga ndi soya).M'kupita kwanthawi, namsongole omwe ndi ovuta kuwongolera amatha kuchotsedwa pamanja.
