Njira yochitira

Ametryn ndi mtundu wa mestriazobenzene selective endothermic conducting herbicide wopezedwa ndi kusinthidwa kwa mankhwala a Ametryn.Ndilo choletsa chambiri cha photosynthesis chokhala ndi zochita za herricidal mwachangu.Poletsa kusamutsidwa kwa ma elekitironi mu photosynthesis ya zomera tcheru, nitrite kudzikundikira masamba kumabweretsa kuvulala kwa zomera ndi imfa, ndipo kusankha kwake kumagwirizana ndi kusiyana kwa zomera zachilengedwe ndi zachilengedwe.

Makhalidwe a ntchito

Itha kulowetsedwa ndi dothi la 0-5 cm kuti ipange mankhwala osanjikiza, kotero kuti namsongole amatha kukhudzana ndi mankhwalawa akamera m'nthaka.Imakhala ndi mphamvu yolamulira udzu womwe wangomera kumene.Pafupipafupi, Ametryn akhoza kulimbikitsa kukula kwa zomera, ndiko kuti, kulimbikitsa kukula kwa masamba aang'ono ndi mizu, kulimbikitsa kuwonjezeka kwa tsamba, tsinde thickening, etc;Pamwamba ndende, ali amphamvu chopinga zotsatira pa zomera.Ametryn amagwiritsidwa ntchito kwambiri m'minda ya nzimbe, citrus, chimanga, soya, mbatata, nandolo ndi karoti kuti athetse udzu wapachaka.Pa mlingo waukulu, imatha kuwononga udzu wosatha ndi udzu wam'madzi, womwe umagwiritsidwa ntchito kwambiri.

Kulembetsa

Malinga ndi funso la China Pesticide Information Network, kuyambira pa Januware 14, 2022, panali ziphaso zovomerezeka 129 zolembetsedwa ku Ametryn ku China, kuphatikiza mankhwala oyambira 9, othandizira 34 osakwatira ndi 86 othandizira.Pakalipano, msika wa Ametryn makamaka umachokera ku ufa wonyowa, ndi 23 dispersible ufa mu mlingo umodzi, wowerengera 67.6%.Mafomu ena a mlingo ndi ma granules otaya madzi ndi kuyimitsidwa, okhala ndi ziphaso zovomerezeka za 5 ndi 6 motsatana;Pali ufa wonyowa 82 pagulu, womwe umawerengera 95%.

Zosakaniza zosakanikirana

Pakali pano, mankhwala ophera udzu m'minda ya nzimbe makamaka ndi sodium dichloromethane (amine) mchere, Ametryn, Ametryn, diazuron, glyphosate ndi zosakaniza zake.Komabe, mankhwala ophera udzu amenewa akhala akugwiritsidwa ntchito m’madera a nzimbe kwa zaka zoposa 20.Chifukwa cha kukana kwa namsongole ku mankhwala ophera udzu amenewa, kufalikira kwa namsongole kukukulirakulira, mpaka kudzetsa masoka.Kusakaniza mankhwala a herbicides kungachedwetse kukana.Fotokozerani mwachidule kafukufuku wapakhomo waposachedwa pa kusakaniza kwa Ametryn, ndipo lembani tsatanetsatane motere:

Ametryn · acetochlor: 40% acetochlor ametryn amagwiritsidwa ntchito popalira mbeu isanakwane m’minda ya chimanga ya m’chilimwe mutabzala, zomwe zimatha kuwongolera.Mphamvu yowongolera ndi yabwino kwambiri kuposa ya wothandizira mmodzi.Wothandizira akhoza kutchuka pakupanga.Ndibwino kuti kuchuluka kwa 667 m2 kukhala 250-300 ml kuphatikiza 50 makilogalamu madzi.Pambuyo kufesa, nthaka pamaso mbande ayenera kupopera mbewu mankhwalawa.Popopera mbewu mankhwalawa, nthaka iyenera kusanjidwa, nthaka ikhale yonyowa, ndipo kupopera mbewu mankhwalawa kuyenera kukhala kofanana.

Ametryn ndi chlorpyrisulfuron: kuphatikiza kwa Ametryn ndi chlorpyrisulfuron mumitundu ya (16-25): 1 idawonetsa zowoneka bwino za synergistic.Pambuyo pozindikira kuti zonse zomwe zilipo pokonzekera ndi 30%, zomwe zili mu chlorpyrisulfuron +Ametryn = 1.5% + 28.5% ndizoyenera kwambiri.

2 Methyl · Ametryn: 48% sodium dichloromethane · Ametryn WP ili ndi mphamvu yowononga namsongole m’munda wa nzimbe.Poyerekeza ndi 56% sodium dichloromethane WP ndi 80% Ametryn WP, 48% sodium dichloromethane ndi Ametryn WP anakulitsa sipekitiramu herbicide ndikuwongolera mphamvu yowongolera.Mphamvu zonse zowongolera ndi zabwino komanso zotetezeka ku nzimbe.

Nitrosachlor · Ametryn: Mlingo woyenera wokwezera 75% Nitrosachlor · Ametryn wettable powder ndi 562.50-675.00 g ai/hm2, womwe ungathe kulamulira bwino udzu wa monocotyledonous, dicotyledonous ndi masamba otakata m’minda ya nzimbe ndipo ndiwotetezedwa ku zomera za nzimbe.

Ethoxy · Ametryn: Ethoxyflufen ndi diphenyl ether herbicide, yomwe imagwiritsidwa ntchito kwambiri pokonza nthaka musanabzale.Zimakhudza kwambiri udzu, udzu, ndi udzu, zomwe zimakhudza kwambiri udzu wamasamba kuposa udzu.Ndizotetezeka kuti mitengo ya apulo iwononge udzu wapachaka m'munda wa zipatso wa apulo ndi acetochlor · Ametryn (38% suspension agent), ndipo mlingo wabwino kwambiri ndi 1140 ~ 1425 g/hm2.

Chidule

Atrazine ndi yokhazikika mwachilengedwe, imakhala ndi nthawi yayitali yogwira ntchito ndipo ndiyosavuta kusunga m'nthaka.Ikhoza kulepheretsa photosynthesis ya zomera ndipo ndi mankhwala opha tizilombo.Itha kupha namsongole mwachangu, ndipo imatha kulowetsedwa ndi dothi la 0-5cm kuti apange wosanjikiza wamankhwala, kuti namsongole akhudze mankhwala akamera.Imakhala ndi mphamvu yolamulira udzu womwe wangomera kumene.Pambuyo pophatikizana, kusakaniza kwake kwachedwetsa kuchitika kwa kukana ndi kuchepetsa zotsalira za nthaka, ndipo kumakhala ndi moyo wautali mu ulamuliro wa udzu m'minda ya nzimbe.
