Intengo Yefekthri Amakhemikhali Ezolimo Izibulala-zinambuzane Zokubulala Ukhula Pendimethalin 33% EC;330 G/L EC

Isingeniso

Imodi Yesenzo

I-Pendimethalin iyi-dinitrotoluidine herbicide.Ngokuyinhloko ivimbela ukuhlukana kwamaseli e-meristem futhi ayithinti ukuhluma kwembewu yokhula.Esikhundleni salokho, imuncwa imiqumbe, iziqu kanye nezimpande ngesikhathi sokuhluma kwembewu yokhula.Kuyasebenza.Ingxenye yokumuncwa kwezitshalo ze-dicotyledonous yi-hypocotyl, futhi ingxenye yokumuncwa kwezitshalo ezi-monocotyledonous ama-buds amancane.Uphawu lomonakalo ukuthi amahlumela amancane kanye nezimpande zesibili zivinjelwe ukufeza inhloso yokukhipha ukhula.

Ukhula olusebenzayo:

Lawula utshani bonyaka kanye nokhula olunamaqabunga abanzi njenge-crabgrass, i-foxtail grass, i-bluegrass, i-wheatgrass, i-goosegrass, i-gray thorn, i-snakehead, i-nightshade, i-pigweed, i-amaranth nobunye utshani baminyaka yonke kanye nokhula lwe-broadleaf.Iphinde ibe nomthelela oqinile wokuvimbela ukukhula kwezithombo ze-dodder.I-Pendimethalin ingavimbela ngokuphumelelayo ukuvela kwama-axillary buds kugwayi, ikhulise isivuno futhi ithuthukise ikhwalithi yamaqabunga kagwayi.

Izitshalo ezifanele:

Ummbila, ubhontshisi wesoya, ukotini, imifino namasimu ezithelo.

Ukusebenzisa Indlela

1. Amasimu kabhontshisi wesoya: Ukwelashwa kwenhlabathi ngaphambi kokuhlwanyela.Njengoba isidakamizwa sine-adsorption eqinile, i-volatility ephansi futhi akulula ukwenza i-photodegrade, ukuxuba inhlabathi ngemuva kokufakwa kwesicelo ngeke kube nomphumela omncane kumphumela wokukhula.Kodwa-ke, uma kunesomiso sesikhathi eside futhi umswakama wenhlabathi uphansi, kufanelekile ukuhlanganisa amasentimitha amathathu kuya kwangu-5 ukuthuthukisa umphumela wokukhula.Sebenzisa u-200-300 ml ka-33% we-pendimethalin EC ngehektare futhi ufafaze umhlabathi ngo-25-40 kg wamanzi ngaphambi kokutshala ubhontshisi wesoya.Uma okuqukethwe kwe-organic matter yomhlabathi kuphezulu futhi i-viscosity yomhlabathi iphezulu, umthamo wezibulala-zinambuzane ungandiswa ngokufanelekile.Lo muthi ungasetshenziswa futhi ekwelashweni kwangaphambi kokuhluma ngemuva kokuhlwanyela kukabhontshisi wesoya, kodwa kufanele usetshenziswe zingakapheli izinsuku ezi-5 ngemuva kokuhlwanyela kukabhontshisi wesoya nangaphambi kokuvela.Emasimini anokhula oluxubile lwe-monocotyledonous kanye ne-dicotyledonous, ingasetshenziswa ngokuhambisana ne-Bentazone.
2. Insimu yommbila: Ingasetshenziswa ngaphambi nangemva kokuvela.Uma isetshenziswa ngaphambi kokumila, kufanele isetshenziswe ezinsukwini ezi-5 ngemuva kokuhlwanyelwa kommbila nangaphambi kokumila.Sebenzisa u-200 ml we-pendimethalin EC engu-33% ngehektare, futhi uyixube ngokulinganayo nama-25 kuya ku-50 kg wamanzi.fafaza.Uma umswakama womhlabathi uphansi ngesikhathi sokufakwa kwesibulala-zinambuzane, inhlabathi ingaxutshwa kancane, kodwa isibulala-zinambuzane akufanele sihlangane nembewu yommbila.Uma izibulala-zinambuzane zisetshenziswa ngemva kwezithombo zombila, kufanele zenziwe ngaphambi kokuba ukhula lwamaqabunga abanzi lukhule amaqabunga eqiniso ama-2 kanye nokhula oluyigramineous lufinyelele esigabeni samaqabunga angu-1.5.Umthamo kanye nendlela yokufaka isicelo iyafana nale engenhla.I-Pendimethalin ingaxutshwa ne-atrazine ukuze kuthuthukiswe umphumela wokulawula ukhula lwe-dicotyledonous.Umthamo oxubile ngu-200 ml we-33% pendimethalin EC kanye nama-83 ml angu-40% wokumiswa kwe-atrazine ngehektare ngayinye.
3. Insimu yamakinati: Angasetshenziselwa ukwelapha inhlabathi ngaphambi kokuhlwanyela noma ngemva kokuhlwanyela.Sebenzisa u-200-300 ml ka-33% we-pendimethalin EC ngehektare (66-99 amagremu wesithako esisebenzayo) bese ufafaza u-25-40 kg wamanzi.
4. Izinkambu zikakotini: Isikhathi sokufaka isibulala-zinambuzane, indlela kanye nomthamo kuyefana nalezo zamasimu amakinati.I-Pendimethalin ingaxutshwa noma isetshenziswe ngokuhambisana nefulon ukulawula ukhula okunzima ukululawula.I-Pendimethalin ingasetshenziswa ngaphambi kokuhlwanyela, futhi i-volturon ingasetshenziswa ekwelapheni esigabeni sezithombo, noma ingxube ye-pendimethalin ne-volturon ingasetshenziswa ngaphambi kokuvela, kanti umthamo wayo ngamunye uyingxenye yalowo wokusetshenziswa okukodwa (isithako esisebenzayo se-pendimethalin ne-volturon). I-volturon iyodwa ingu-66.7~ 133.3 g/mu), sebenzisa u-100-150 ml ngayinye ye-pendimethalin EC engu-33% kanye ne-fulfuron ngemu, bese ufafaza u-25-50 kg wamanzi ngokulinganayo.
5. Iziqephu zemifino: Ezindaweni zemifino ezinembewu eqondile njengamalikhi, ama-shallots, iklabishi, ukholifulawa, namahlumela kabhontshisi wesoya, zinganiselwa ngemva kokuhlwanyela nokugcotshwa kwezibulala-zinambuzane.Sebenzisa u-100 kuya ku-150 ml ka-33% we-pendimethalin EC ngehektare ngalinye kanye no-25 kuya ku-40 ml wamanzi.Ikhilogremu isifutho, umuthi uhlala cishe izinsuku ezingama-45.Ngemifino enembewu eqondile enesikhathi eside sokukhula, njengama-leeks ezithombo, isibulala-zinambuzane singaphinda sisetshenziswe ezinsukwini ezingu-40 kuya kwezingu-45 ngemva kokufakwa kokuqala, okungalawula ngokuyisisekelo ukulimala kokhula kwemifino phakathi nesikhathi sokukhula.Amasimu emifino atshalwe kabusha: Iklabishi, iklabishi, ulethisi, isitshalo seqanda, utamatisi, upelepele oluhlaza neminye imifino kungafuthwa ngaphambi kokutshala noma ngemva kokutshala ukuze kubambezeleke izithombo.Sebenzisa u-100~200 ml ka-33% we-pendimethalin EC ngehektare ngalinye.Fafaza u-30 ~ 50kg wamanzi.
6. Insimu kagwayi: Isibulala-zinambuzane singasetshenziswa ngemva kokutshalwa kabusha kukagwayi.Sebenzisa u-100~200 ml ka-33% we-pendimethalin EC ngehektare futhi ufafaze ngokulinganayo ku-30~50 kg wamanzi.Ngaphezu kwalokho, ingasetshenziswa njenge-inhibitor yehlumela likagwayi, enenzuzo ekuthuthukiseni isivuno kanye nekhwalithi kagwayi.
7. Insimu yomoba: Isibulala-zinambuzane singasetshenziswa ngemva kokutshala umoba.Sebenzisa u-200~300 ml ka-33% we-pendimethalin EC ngehektare futhi ufafaze ngokulinganayo ku-30~50 kg wamanzi.
8. Insimu yezithelo: Ngesikhathi sokukhula kwezihlahla zezithelo, ngaphambi kokuvela kokhula, sebenzisa u-200-300 ml we-pendimethalin EC engu-33% ngehektare ngalinye kanye no-50-75 kg wamanzi wokuhlanza inhlabathi.Ukwandisa i-spectrum ye-herbicidal, ingaxutshwa ne-atrazine.

Izinyathelo zokuzivikela

1. I-Pendimethalin inobuthi obukhulu ekudobeni, ngakho-ke yisebenzise ngokucophelela futhi ungangcolisi imithombo yamanzi namachibi ezinhlanzi.
2. Uma ugcoba izibulala-zinambuzane emasimini ommbila nawesoya, ukujula kokuhlwanyela kufanele kube ngamasentimitha amathathu kuya kwayisi-6 futhi kuvalwe ngenhlabathi ukuvimbela imbewu ukuthi ingathintani nezibulala-zinambuzane.
3. Lapho welapha inhlabathi, sebenzisa izibulala-zinambuzane kuqala bese unisela, okungase kwandise ukugcwala komhlabathi kwezibulala-zinambuzane futhi kunciphise ukulimala kwezibulala-zinambuzane.Emasimini anokhula oluningi lwe-dicotyledonous, ukuxuba neminye imithi yokubulala ukhula kufanele kubhekwe.
4. Emhlabathini oyisihlabathi onokuqukethwe okuphansi kwezinto eziphilayo, akufaneleki ukufaka isicelo ngaphambi kokumila.
