Indlela yokwenza

I-Ametryn iwuhlobo lwe-mestriazobenzene olukhethayo lwe-endothermic conducting herbicide olutholwe ngokuguqulwa kwamakhemikhali e-Ametryn.Kuyi-inhibitor evamile ye-photosynthesis enesenzo esisheshayo se-hericidal.Ngokuvimbela ukudluliswa kwe-electron ku-photosynthesis yezitshalo ezibucayi, ukunqwabelana kwe-nitrite emaqabunga kuholela ekulimaleni nasekufeni kwezitshalo, futhi ukukhetha kwayo kuhlobene nomehluko ekuphenduleni kwezitshalo kwemvelo kanye ne-biochemical.

Izici zomsebenzi

Ingakhangiswa ngenhlabathi engu-0-5 cm ukwenza ungqimba lomuthi, ukuze ukhula luthinte umuthi lapho luhluma emhlabathini.Inomphumela omuhle kakhulu wokulawula ukhula olusanda kumila.Ekugxilweni okuphansi, i-Ametryn ingakhuthaza ukukhula kwezitshalo, okungukuthi, ikhuthaze ukukhula kwamahlumela amancane nezimpande, ikhuthaze ukwanda kwendawo yamaqabunga, ukuqina kwesiqu, njll;Ekugxilweni okuphezulu, kunomphumela oqinile wokuvimbela izitshalo.I-Ametryn isetshenziswa kakhulu kumoba, i-citrus, ummbila, ubhontshisi wesoya, amazambane, uphizi kanye nezaqathi emasimini ukulawula ukhula lwaminyaka yonke.Ngemithamo ephezulu, ingalawula ukhula olungapheli kanye nokhula lwasemanzini, olusetshenziswa kakhulu.

Ukubhalisa

Ngokombuzo we-China Pesticide Information Network, kusukela ngoJanuwari 14, 2022, bekunezitifiketi ezivumelekile eziyi-129 ezibhaliselwe i-Ametryn e-China, okuhlanganisa nezidakamizwa eziyi-9 zoqobo, ama-ejenti angama-34 angawodwa kanye nama-ejenti ahlanganisiwe angama-86.Njengamanje, imakethe ye-Ametryn ngokuyinhloko isekelwe ku-powder emanzi, ene-powder ehlakazekayo engu-23 ngethamo elilodwa, ibalwa ku-67.6%.Amanye amafomu omthamo ama-granules ahlakazeka amanzi kanye nokulengiswa, kanye nezitifiketi zokubhalisa ezisebenzayo ezi-5 nezisi-6 ngokulandelana;Kunezimpushana ezimanzi ezingama-82 enkomponi, ezibalelwa ku-95%.

Izithako ezisebenzayo ezixutshwayo

Njengamanje, imithi yokubulala ukhula ngemva kokuhluma emasimini omoba ngokuyinhloko i-sodium dichloromethane (amine) usawoti, i-Ametryn, i-Ametryn, i-diazuron, i-glyphosate nezingxube zayo.Nokho, le michiza yokubulala ukhula isineminyaka engaphezu kuka-20 isetshenziswa endaweni yomoba.Ngenxa yokumelana okusobala kokhula kule mithi yokubulala ukhula, ukuvela kokhula kuya ngokuya kuba kubi kakhulu, kubangele nezinhlekelele.Ukuxuba ama-herbicides kungabambezela ukumelana.Fingqa ucwaningo lwamanje lwasekhaya ngengxube ye-Ametryn, bese ubhala imininingwane ngale ndlela elandelayo:

I-Ametryn · acetochlor: 40% i-acetochlor ametryn isetshenziselwa ukuhlakula ngaphambi kwezithombo emasimini ommbila ehlobo ngemva kokuhlwanyela, okunomphumela omuhle wokulawula.Umphumela wokulawula ungcono kakhulu kunowe-ejenti eyodwa.I-ejenti ingathandwa ekukhiqizeni.Kunconywa ukuthi inani elingu-667 m2 libe ngu-250-300 ml kanye no-50 kg wamanzi.Ngemuva kokuhlwanyela, inhlabathi ngaphambi kokutshala kufanele ifafazwe.Lapho ufutha, umhlabathi kufanele ulinganiswe, umhlabathi ube manzi, futhi ukufafaza kufanele kube okulinganayo.

I-Ametryn ne-chlorpyrisulfuron: inhlanganisela ye-Ametryn ne-chlorpyrisulfuron ebangeni le-(16-25): i-1 ibonise umphumela ocacile we-synergistic.Ngemva kokunquma ukuthi okuqukethwe okuphelele kokulungiswa kungu-30%, okuqukethwe kwe-chlorpyrisulfuron+Ametryn=1.5%+28.5% kufanelekile kakhulu.

2 Methyl · I-Ametryn: 48% sodium dichloromethane · I-Ametryn WP inomphumela omuhle wokulawula ukhula ensimini kamoba.Uma kuqhathaniswa no-56% we-sodium dichloromethane WP kanye no-80% we-Ametryn WP, u-48% we-sodium dichloromethane kanye ne-Ametryn WP yandise i-spectrum yokubulala ukhula futhi yathuthukisa umphumela wokulawula.Umphumela wokulawula uwonke muhle futhi uphephile kumoba.

I-Nitrosachlor · I-Ametryn: Isilinganiso esifanele sokukhushulwa sika-75% Nitrosachlor · I-Ametryn wettable powder ingu-562.50-675.00 g ai/hm2, engalawula ngempumelelo ukhula oluyi-monocotyledonous, dicotyledonous kanye namahlamvu abanzi ezimobeni futhi iphephile ekukhuleni kwezitshalo zikamoba.

I-Ethoxy · I-Ametryn: I-Ethoxyflufen iwumuthi wokubulala ukhula i-diphenyl ether, osetshenziswa kakhulu ukwelapha inhlabathi ngaphambi kokutshala.Inomthelela omkhulu otshanini obunamaqabunga abanzi, inhlaka kanye notshani, phakathi kwawo umthelela wokulawula etshanini obuneqabunga elibanzi uphakeme kunotshani.Kuphephile ezihlahleni zama-apula ukulawula ukhula lwaminyaka yonke ensimini yama-apula nge-acetochlor · I-Ametryn (i-agent engu-38% yokumiswa), futhi umthamo ongcono kakhulu ngu-1140~1425 g/hm2.

Isifinyezo

I-Atrazine izinzile emvelweni, inesikhathi eside esisebenzayo futhi kulula ukuyigcina emhlabathini.Ingavimbela i-photosynthesis yezitshalo futhi iwumuthi okhethayo.Ingabulala ukhula ngokushesha, futhi ingakhanyiswa ngenhlabathi engu-0-5cm ukuze yakhe ungqimba lomuthi, ukuze ukhula luthinte umuthi lapho luhluma.Inomphumela omuhle kakhulu wokulawula ukhula olusanda kumila.Ngemva kokuhlanganiswa, ingxube yawo ibambezele ukwenzeka kokumelana nokuncipha kwezinsalela zenhlabathi, futhi iphila isikhathi eside ekulawuleni ukhula emasimini omoba.
