Mawu Oyamba

Kachitidwe

Pendimethalin ndi dinitrotoluidine herbicide.Zimalepheretsa kugawanika kwa maselo a meristem ndipo sizikhudza kumera kwa mbewu za udzu.M'malo mwake, imatengeka ndi masamba, zimayambira ndi mizu panthawi ya kumera kwa njere za udzu.Zikugwira.Mayamwidwe a zomera za dicotyledonous ndi hypocotyl, ndipo gawo la mayamwidwe a zomera za monocotyledonous ndi masamba aang'ono.Chizindikiro chowonongeka ndi chakuti masamba ang'onoang'ono ndi mizu yachiwiri amaletsedwa kuti akwaniritse cholinga chopalira.

Udzu wachangu:

Thirani udzu wapachaka ndi udzu wamasamba otakata monga nkhanu, udzu wa foxtail, bluegrass, wheatgrass, goosegrass, gray thorn, snakehead, nightshade, pigweed, amaranth ndi udzu wina wapachaka ndi namsongole.Imakhalanso ndi mphamvu yolepheretsa kukula kwa mbande za dodder.Pendimethalin imatha kuletsa bwino kukula kwa masamba a axillary mufodya, kuonjezera zokolola ndikuwongolera masamba a fodya.

Mbewu zoyenera:

Chimanga, soya, thonje, masamba ndi minda ya zipatso.

Kugwiritsa Ntchito Njira

1. Minda ya soya: Kuthira nthaka musanafese.Popeza mankhwala ali adsorption amphamvu, otsika kusakhazikika ndipo si kophweka photodegrade, kusakaniza nthaka pambuyo ntchito adzakhala ndi zotsatira zochepa pa Kupalira kwenikweni.Komabe, ngati pali chilala chanthawi yayitali komanso chinyezi m'nthaka ndi chochepa, ndikofunikira kusakaniza 3 mpaka 5 centimita kuti muwongolere bwino.Gwiritsani ntchito 200-300 ml ya 33% pendimethalin EC pa ekala ndikupopera nthaka ndi 25-40 kg ya madzi musanabzale soya.Ngati dothi lili ndi zinthu zambiri komanso kukhuthala kwa nthaka kuli kwakukulu, mlingo wa mankhwala ophera tizilombo ukhoza kuonjezedwa moyenerera.Mankhwalawa angagwiritsidwenso ntchito pochiza chisanadze akayamba kubzala soya, koma ayenera kugwiritsidwa ntchito pasanathe masiku 5 pambuyo kufesa soya ndi pamaso zikamera.M'minda yokhala ndi namsongole wosakanikirana wa monocotyledonous ndi dicotyledonous, itha kugwiritsidwa ntchito molumikizana ndi Bentazone.
2. Munda wa chimanga: Itha kugwiritsidwa ntchito isanayambe komanso itatha.Ngati chitayikidwa chisanamere, chiyenera kupakidwa pasanathe masiku asanu chimanga chitafesedwa komanso chisanamere.Gwiritsani ntchito 200 ml ya 33% pendimethalin EC pa ekala, ndi kusakaniza mofanana ndi 25 mpaka 50 kg ya madzi.utsi.Ngati chinyontho cha nthaka chili chochepa pothira mankhwala ophera tizilombo, nthaka imatha kusakanizidwa pang'ono, koma mankhwala sayenera kukhudzana ndi njere za chimanga.Ngati mankhwala ophera tizilombo agwiritsidwa ntchito pambuyo pa mbande za chimanga, ziyenera kuchitidwa udzu usanayambe kukula 2 masamba enieni ndi namsongole wa gramineous kufika pa tsamba 1.5.Mlingo ndi njira yogwiritsira ntchito ndizofanana ndi zomwe tafotokozazi.Pendimethalin ikhoza kusakanikirana ndi atrazine kuti ipititse patsogolo zotsatira za kulamulira namsongole wa dicotyledonous.Mlingo wosakanikirana ndi 200 ml ya 33% pendimethalin EC ndi 83 ml ya 40% kuyimitsidwa kwa atrazine pa ekala.
3. Munda wa mtedza: Utha kugwiritsidwa ntchito pokonza nthaka musanafese kapena mukamaliza kufesa.Gwiritsani 200-300 ml ya 33% pendimethalin EC pa ekala (66-99 magalamu a yogwira pophika) ndi kupopera 25-40 makilogalamu madzi.
4. Minda ya thonje: Nthawi yothira mankhwala ophera tizilombo, njira yake ndi mlingo wake ndi wofanana ndi wa m’minda ya mtedza.Pendimethalin ikhoza kusakanikirana kapena kugwiritsidwa ntchito pamodzi ndi fulon kuti athetse udzu wovuta kulamulira.Pendimethalin angagwiritsidwe ntchito musanafesedwe, ndipo volturon angagwiritsidwe ntchito pochiza mbande siteji, kapena osakaniza pendimethalin ndi volturon angagwiritsidwe ntchito zisanatulukire, ndipo mlingo wa aliyense ndi theka la ntchito limodzi (chogwira pophika. volturon yokha ndi 66.7~ 133.3 g/mu), gwiritsani ntchito 100-150 ml iliyonse ya 33% pendimethalin EC ndi fulfuron pa mu, ndi kupopera 25-50 kg ya madzi mofanana.
5. Masamba amasamba: Paminda yamasamba yodzala mbewu mwachindunji monga leeks, shallots, kabichi, kolifulawa, ndi mphukira za soya, amatha kuthiriridwa akabzala ndikuthira mankhwala ophera tizilombo.Gwiritsani ntchito 100 mpaka 150 ml ya 33% pendimethalin EC pa ekala ndi 25 mpaka 40 ml ya madzi.Kupopera kwa kilogalamu, mankhwalawa amakhala pafupifupi masiku 45.Kwa ndiwo zamasamba zokhala ndi mbewu zachindunji zokhala ndi nthawi yayitali, monga ma leeks, mankhwala ophera tizilombo amatha kuyikidwanso patatha masiku 40 mpaka 45 mutatha kugwiritsa ntchito koyamba, zomwe zimatha kuwononga udzu wamasamba nthawi yonse yakukula.M'minda yamasamba: Kabichi, kabichi, letesi, biringanya, phwetekere, tsabola wobiriwira ndi masamba ena amatha kuwaza musanawoke kapena mutabzala kuti muchepetse mbande.Gwiritsani ntchito 100 ~ 200 ml ya 33% pendimethalin EC pa ekala.Utsi 30-50kg madzi.
6. Munda wa Fodya: Mankhwalawa atha kupakidwa fodya atawokedwa.Gwiritsani ntchito 100 ~ 200 ml ya 33% pendimethalin EC pa ekala ndikupopera mofanana pa 30 ~ 50 kg ya madzi.Kuphatikiza apo, itha kugwiritsidwa ntchito ngati choletsa kuphukira kwa fodya, chomwe chimapindulitsa pakuwongolera zokolola komanso mtundu wa fodya.
7. Munda wa nzimbe: Mankhwala atha kupakidwa nzimbe akabzalidwa.Gwiritsani ntchito 200 ~ 300 ml ya 33% pendimethalin EC pa ekala ndikupopera mofanana pa 30 ~ 50 kg ya madzi.
8. Munda wa Zipatso: Panyengo ya kukula kwa mitengo yazipatso, udzu usanatuluke, gwiritsani ntchito 200-300 ml ya 33% pendimethalin EC pa ekala ndi madzi okwana 50-75 kg pokonza nthaka.Kukulitsa sipekitiramu ya herbicidal, imatha kusakanikirana ndi atrazine.

Kusamalitsa

1. Pendimethalin ndi poizoni kwambiri kwa nsomba, choncho igwiritseni ntchito mosamala ndipo musawononge magwero a madzi ndi maiwe a nsomba.
2. Pothira mankhwala m’minda ya chimanga ndi soya, kufesa kukuyenera kukhala 3 mpaka 6 centimita ndi kukutidwa ndi dothi kuti mbeu zisakhudze mankhwala.
3. Pothirira dothi, thirirani mankhwala kaye kenako kuthirira, zomwe zingapangitse kuti dothi likhale lodzaza ndi mankhwala ophera tizilombo komanso kuchepetsa kuwonongeka kwa mankhwala.M'minda yomwe ili ndi namsongole wambiri wa dicotyledonous, kusakaniza ndi mankhwala ena a herbicides kuyenera kuganiziridwa.
4. Pa dothi lamchenga lomwe lili ndi zinthu zochepa za organic, sikoyenera kuyikapo musanamere.
