2. Miyezo yaukadaulo

(1) Kulima soya ndi chimanga mlimi

M’dera la kum’mwera chakumadzulo, mvula imakhala yochuluka, ndipo pali mitundu yambiri ya namsongole, yomwe ndi yovuta kuithetsa.Chimanga chimabzalidwa soya isanabzalidwe ndipo kugwiritsa ntchito mankhwala ophera udzu “kupha pamodzi”.Chimanga chikafesedwa, gwiritsani ntchito metolachlor (kapena acetochlor) + thifensulfuron-methyl kuti mutseke nthaka.Ngati pali udzu m'munda chimanga chisanafesedwe, mutha kugwiritsa ntchito kupopera kwa glufosinate-ammonium;Kutsekera kwa nthaka sikoyenera Ngati mankhwala a tsinde ndi masamba akufunika, nicosulfuron + fluroxypyr (kapena clopyralid, bentazone) angagwiritsidwe ntchito kulunjika (malo obzala chimanga) tsinde ndi utsi wa masamba pamasamba 3 mpaka 5 pambuyo pa mbande za chimanga.

Masiku atatu soya isanayambe kufesa, glufosinate idasankhidwa kuti ipopedwe molunjika m'mizere yopanda kanthu m'munda.Mukabzala komanso mbande zisanachitike, nthaka imatsekedwa ndi mankhwala ophera tizilombo monga metolachlor (kapena acetochlor) + thifensulfuron-methyl.Ngati kusindikiza kwa nthaka sikuli koyenera ndipo kupopera mbewu mankhwalawa kwa tsinde ndi masamba kumafunika, quizalofop-pp (kapena yogwira ntchito kwambiri fluroxyfop-pp, fluazifop-pp, clethodim) + B Carboxyfluorfen (kapena bentazone) yolunjika (malo obzala soya) tsinde ndi utsi wa masamba.

(2) Kulima soya ndi chimanga

Ku Huanghuaihai, m'katikati ndi m'munsi mwa Mtsinje wa Yangtze, ndi kumpoto chakumadzulo kwa China, soya ndi chimanga zimafesedwa nthawi yomweyo, ndipo mankhwala ophera udzu amagwiritsidwa ntchito makamaka pambuyo pa kufesa ndi mankhwala osindikizira a nthaka, omwe amafunika kumalizidwa mkati mwa 2. masiku atabzala.Kusindikiza kwa dothi kumachitika pogwiritsa ntchito metolachlor yoyengedwa (kapena metolachlor, acetochlor) + fensulfame (kapena thifensulfuron-methyl) ndi othandizira ena.Dothi likamatidwa ndi mankhwala ophera udzu m'munda momwe chiputu chapitacho ndi tirigu, ndi bwino kubzala mozungulira kuchotsa ziputu, kupanga chinyezi, kenako kubzala ndikuthira mankhwala musanabzale;m'minda yomwe mapesi a tirigu amafalitsidwa mwachindunji, m'pofunika kuonjezera kumwa kwa madzi pa mu, ndikuyika mankhwala ophera tizilombo ngati n'kotheka.Pambuyo pake, madzi mu nthawi;m'madera ndi chilala ndi mvula yamkuntho monga Kumpoto chakumadzulo, ndi bwino kusakaniza nthaka pambuyo ntchito herbicides, ndi madzi mu nthawi imene zinthu kulola.

Ngati kusindikiza kwa dothi sikuli koyenera ndipo chithandizo cha tsinde ndi masamba chikufunika, chingagwiritsidwe ntchito pamasamba 3-5 pambuyo pa mbande za chimanga, 2-3 soya pamasamba atatu, ndi namsongole pa 2-5 tsamba lamasamba.Malinga ndi momwe udzu ulili, chimanga chimatha kusankhidwa.Nicosulfuron (kapena oxaflumezone) + bentazone (kapena fluroxypyr), ndi minda ya soya amasankha quizalofop-p-ethyl (kapena fluroxyfop yogwira ntchito kwambiri) + bentazone (kapena fluroxyfen-ethanol) ) Kupopera mbewu molunjika kwa tsinde pakupalira (gwiritsani ntchito makatani akuthupi kuti mulekanitse chimanga ndi soya popopera mankhwala).Pambuyo pake, udzu wovuta kuumitsa ukhoza kuchotsedwa pamanja.
