1. Intshayelelo yeDiquat

IDiquat yeyona nto yesithathu idumileyo emhlabeni emva kweglyphosate kunye neparaquat.IDiquat sisichiza sokutshabalalisa ukhula kwibipyridyl.Ngenxa yokuba iqulethe i-athomu ye-bromine kwinkqubo ye-bipyridine, ineempawu ezithile zenkqubo, kodwa ayiyi kulimaza iingcambu zezityalo.Inokuqhutyelwa phezulu nge-phloem yesityalo, ngoko ke ingcono kune-glyphosate.kwaye iglufosinate ibulala ukhula ngokukhawuleza nangempumelelo.Xa lusetyenziswa emasimini, ukhula oluvunjululweyo ludla ngokubulawa phambi nasemva kokuhlwayelwa kwesityalo naphambi kokuntshula, okanye ukutshiza okuphakathi kwemiqolo kusetyenziswa emva kwexesha lokuhluma kwezityalo.Ngexesha elifanayo, i-diquat nayo i-desiccant yoqhagamshelwano kwaye ingasetyenziselwa njenge-ejenti yokubuna / yokuvuthwa ngaphambi nangemva kokuvuna kunye ne-desiccant yezityalo zembewu.

2. Uluhlu lwezityalo olusebenzayo lwe-diquat

IDiquat isebenza ngakumbi kuneparaquat kwaye inefuthe elingcono kukhula olunamagqabi abanzi.Ilungele ukususwa kokhula phambi kokuhlwayelwa kumasimi angalinywanga nangalinywanga, imiyezo, kunye nokuhlakula phakathi kwemiqolo yezityalo.Isenokusetyenziswa nasekuvuneni izityalo ezifana neembotyi zesoya, iitapile kunye nomqhaphu.Eyangaphambili ibangela ukubuna kunye nokuchithwa kwamagqabi.

3. Ziziphi iingenelo ze-diquat?

①. Iipropati ezisebenza ngokukhawuleza: I-Diquat kunye ne-paraquat zombini zi-bipyridyl herbicides kwaye zineempawu ezifanayo ngokweempawu zokutshabalalisa ukhula.Ibulala ukhula ngokukhawuleza kuneparaquat.Isebenza kwangolo suku, kwaye ingca iqala ukufa kwiiyure ezingama-24.Imvula ine iyure enye emva kokutshiza, enempembelelo encinci ekusebenzeni.

②.Ukhuseleko olulungileyo, amanzi kunye nolondolozo lomhlaba: Nangona i-diquat ineempawu ezithile zenkqubo, ayisayi konakalisa inkqubo yeengcambu zezityalo, kwaye ikakhulu ibulala ukudibana emva kwayo yonke into.Ke ngoko, i-diquat ikwaqhuba neempawu zokhuseleko zeparaquat ngaphandle kwentsalela kwaye akukho bungozi bokuqhuba.Ekubeni ingca yotshaba ingazibulali iingcambu, inceda ukulondoloza amanzi nokulondoloza umhlaba, yaye iinduli zamasimi akulula ukudilika.

③.Ifuthe elikhethekileyo kukhula lwamagqabi abanzi: IDiquat inempembelelo yokulawula engcono kuneglufosinate kukhula oluthile oluxhathisayo, ngakumbi ukhula lwamagqabi abanzi.

④.Ukumelana nobushushu obuphantsi: Xa iqondo lobushushu lingaphantsi kwe-15℃, umphumo wokukhula uluncedo ngakumbi kune-glufosinate-ammonium.

4. Uyisebenzisa njani iDiquat ngokufanelekileyo?

①.Ukukhula kwinkunkuma: Enye i-glyphosate inokongezwa ngokufanelekileyo, kwaye ukuphindaphinda kokhula kwinqanaba elilandelayo kuya kuncitshiswa kakhulu.Ngokumalunga nedosi ethile, ungaqala ulinge kwindawo encinci ngokweemeko zokhula zalapha.

②. Kolunye ukhula olulawulwa yiGramineae, unokongeza i-quizalofop, i-clethodim, i-flufenofop, njl.

③.Ekubeni i-diquat ikakhulu yeyokubulala ukudibana, xa utshiza i-diquat, kufuneka itshizwe ngokucokisekileyo nangokulinganayo.I-Penents efana ne-silicon ye-organic nayo inokongezwa ukuze umphezulu wokhula ushiye unxibelelwano olupheleleyo kwaye ufunxe i-diquat ukuphumeza iziphumo ezingcono.Isiphumo esihle sokubulala ukhula.

④.Xa udiluting i-diquat, musa ukusebenzisa amanzi omlambo amdaka ukunqanda ukusebenza kwechiza ekuncipheni.

⑤.Zama ukusebenzisa isibulali-zinambuzane emva kokuba umbethe uphuphuma ekuseni.Xa ubonakaliswe ekukhanyeni kwelanga emini, umphumo wokudibanisa uya kubonakala kwaye umphumo uya kukhawuleza.(Faka iyeza ebusuku phambi kokuba kubekho umbethe, ngoko ke iyeza liya kusebenza kakhulu)
