Indlela yokusebenza

I-Ametryn luhlobo oluthile lwe-mestriazobenzene endothermic eqhuba i-herbicide efunyenwe ngokuguqulwa kwemichiza ye-Ametryn.Yinto eqhelekileyo inhibitor yephotosynthesis enentshukumo ekhawulezayo ye-herricidal.Ngokuthintela ukuhanjiswa kwe-electron kwi-photosynthesis yezityalo ezibuthathaka, ukuqokelelwa kwe-nitrite kumagqabi kukhokelela ekulimazeni kwezityalo kunye nokufa, kwaye ukukhethwa kwayo kuhambelana nokungafani kwezityalo eziphilayo kunye ne-biochemical reaction.

Iimpawu zomsebenzi

Iyakwazi ukubhengezwa ngomhlaba we-0-5 cm ukwenza umaleko weyeza, ukuze ukhula luqhagamshelane neyeza xa luhluma emhlabeni.Ineyona mpembelelo ilungileyo yokulawula ukhula olusandul’ ukuntshula.Kwinqanaba eliphantsi, i-Ametryn inokukhuthaza ukukhula kwezityalo, oko kukuthi, ukukhuthaza ukukhula kweengcambu ezincinci kunye neengcambu, ukukhuthaza ukwanda kwendawo yamagqabi, ukuqina kwesiqu, njl.Ekugxininiseni okuphezulu, kunempembelelo enamandla yokuthintela kwizityalo.IAmetryn isetyenziswa kakhulu kumasimi ommoba, isitrasi, umbona, iimbotyi zesoya, iitapile, iertyisi kunye namasimi eminqathe ukulawula ukhula lonyaka.Kwidosi ephezulu, inokulawula ukhula olungapheliyo kunye nokhula lwasemanzini, olusetyenziswa kakhulu.

Ubhaliso

Ngokombuzo we-China Pesticide Information Network, ukusukela nge-14 kaJanuwari 2022, bekukho izatifikethi ezisebenzayo eziyi-129 ezibhaliselwe i-Ametryn e-China, kubandakanywa neziyobisi eziyi-9 zoqobo, iiarhente ezingatshatanga ezingama-34 kunye ne-86 yeearhente ezihlanganisiweyo.Okwangoku, imarike ye-Ametryn isekelwe ikakhulu kwi-powder emanzi, kunye ne-23 ye-powder dispersible kwi-dose enye, ibalwa kwi-67.6%.Ezinye iifom zedosi ziigranuli ezihlakazekayo zamanzi kunye nokunqunyanyiswa, kunye nezatifikethi ezisebenzayo ezi-5 kunye nezi-6 ngokulandelelana kwazo;Kukho i-82 ye powders ezimanzi kwi-compound, ezibalelwa kwi-95%.

Izithako ezisebenzayo ezixutywayo

Okwangoku, imichiza yokutshabalalisa ukhula emva kokuhluma kumasimi ommoba ikakhulu yi-sodium dichloromethane (amine) ityuwa, i-Ametryn, i-Ametryn, i-diazuron, i-glyphosate kunye nemixube yazo.Noko ke, le michiza yokutshabalalisa ukhula ibisetyenziswa kwindawo yommoba ngaphezu kweminyaka engama-20.Ngenxa yokuxhathisa okucacileyo kokhula kula michiza yokutshabalalisa ukhula, ukuvela kokhula kuya kusiba nzima ngakumbi, kude kubangele neentlekele.Ukuxuba imichiza yokutshabalalisa ukhula kunokulibazisa ukuxhathisa.Shwankathela uphando lwasekhaya lwangoku kumxube we-Ametryn, kwaye udwelise ezinye iinkcukacha ngolu hlobo lulandelayo:

I-Ametryn · i-acetochlor: i-40% i-acetochlor ametryn isetyenziselwa ukuhlakula kwangaphambi kwezithole kumasimi ombona ehlotyeni emva kokuhlwayela, nto leyo inefuthe elifanelekileyo lokulawula.Impembelelo yokulawula ingcono kakhulu kune-arhente enye.I-ejenti inokuthandwa kwimveliso.Kucetyiswa ukuba inani le-667 m2 libe yi-250-300 ml kunye ne-50 kg yamanzi.Emva kokuhlwayela, umhlaba phambi kwezithole kufuneka utshizwe.Xa utshiza, umphezulu womhlaba kufuneka ulinganiswe, umhlaba ube manzi, kwaye ukutshiza kufuneka kulingane.

I-Ametryn kunye ne-chlorpyrisulfuron: ukudibanisa kwe-Ametryn kunye ne-chlorpyrisulfuron kuluhlu lwe-(16-25): i-1 ibonise umphumo ocacileyo we-synergistic.Emva kokugqiba ukuba umxholo opheleleyo wokulungiselela u-30%, umxholo we-chlorpyrisulfuron + Ametryn = 1.5% + 28.5% ufanelekile ngakumbi.

2 Methyl · Ametryn: 48% sodium dichloromethane · I-Ametryn WP inempembelelo entle yokulawula ukhula kwintsimi yommoba.Xa kuthelekiswa ne-56% ye-sodium dichloromethane WP kunye ne-80% ye-Ametryn WP, i-48% ye-sodium dichloromethane kunye ne-Ametryn WP yandise i-spectrum ye-herbicide kwaye yaphucula umphumo wokulawula.Isiphumo solawulo jikelele silungile kwaye sikhuselekile kummoba.

I-Nitrosachlor · Ametryn: Idosi efanelekileyo yokunyusa ye-75% ye-Nitrosachlor · I-Ametryn powder emanzi yi-562.50-675.00 g ai/hm2, enokulawula ngokufanelekileyo i-monocotyledonous, i-dicotyledonous kunye nokhula olunamagqabi abanzi kumasimi ommoba kwaye ikhuselekile ekukhuleni kwezityalo zommoba.

I-Ethoxy · Ametryn: I-Ethoxyflufen sisichiza se-diphenyl ether, esisetyenziswa kakhulu kunyango lomhlaba phambi kokuba izithole.Inefuthe lolawulo oluphezulu kwingca yamagqabi abanzi, ingca kunye nengca, apho ifuthe lolawulo kwingca yamagqabi abanzi liphezulu kunengca.Kukhuselekile kwimithi yama-apula ukulawula ukhula lonyaka kwi-apula ye-acetochlor · I-Ametryn (i-38% ye-suspension agent), kwaye i-dosage engcono kakhulu yi-1140 ~ 1425 g / hm2.

Isishwankathelo

I-Atrazine izinzile kwindalo, inexesha elide elisebenzayo kwaye kulula ukuyigcina emhlabeni.Inokuthintela iphotosynthesis yezityalo kwaye ngumchiza okhethiweyo.Ingabulala ukhula ngokukhawuleza, kwaye ingabhengezwa ngomhlaba oyi 0-5cm ukwenza umaleko weyeza, ukuze ukhula ludibane neyeza xa luhluma.Ineyona mpembelelo ilungileyo yokulawula ukhula olusandul’ ukuntshula.Emva kokudibanisa, umxube wawo ulibazise ukwenzeka kokuxhathisa kunye nokunciphisa intsalela yomhlaba, kwaye unobomi obude ekulawuleni ukhula kumasimi ommoba.
