1. Isingeniso se-Diquat

I-Diquat ingumuthi wesithathu wokubulala ukhula odume kakhulu emhlabeni ngemuva kwe-glyphosate ne-paraquat.I-Diquat iwumuthi wokubulala ukhula i-bipyridyl.Ngenxa yokuthi iqukethe i-athomu ye-bromine ohlelweni lwe-bipyridine, inezici ezithile zesistimu, kodwa ngeke ilimaze izimpande zezitshalo.Ingaqhutshelwa phezulu nge-phloem yesitshalo, ngakho-ke ingcono kune-glyphosate.futhi i-glufosinate ibulala ukhula ngokushesha nangempumelelo.Uma isetshenziswa emasimini, ukhula oluvubukuliwe luvame ukubulawa ngaphambi nangemuva kokuhlwanyela kwezitshalo nangaphambi kokuhluma, noma ukufuthwa kwemigqa phakathi kwemigqa kusetshenziswa ekupheleni kwesikhathi sokuhluma kwezitshalo.Ngesikhathi esifanayo, i-diquat iphinde ibe i-desiccant yokuxhumana futhi ingasetshenziswa njenge-ejenti yokubuna / yokuvuthwa ngaphambi nangemva kokuvuna futhi njenge-desiccant yezitshalo zembewu.

2. Uhla lwezitshalo olusebenzayo lwe-diquat

I-Diquat iphumelela kakhulu kune-paraquat futhi inomphumela ongcono okhulani olunamaqabunga abanzi.Ilungele ukuhluma ngaphambi kokuhlwanyela ezindaweni ezingalinyiwe nezingalimi, ezinsimini zezithelo, kanye nokuhlakula phakathi kwemigqa yezitshalo.Ingase futhi isetshenziselwe ukuvuna izitshalo ezifana nobhontshisi wesoya, amazambane, nokotini.Owokuqala kudala ukubuna kanye nokubola.

3. Yiziphi izinzuzo ze-diquat?

①. Izakhiwo ezisebenza ngokushesha: I-Diquat ne-paraquat womabili ama-bipyridyl herbicides futhi anezici ezifanayo ngokwezindawo zokubulala ukhula.Ibulala ukhula ngokushesha kakhulu kune-paraquat.Iqala ukusebenza ngosuku olufanayo, futhi utshani buqala ukufa phakathi namahora angu-24.Imvula ine ihora elilodwa ngemva kokufafaza, okunomthelela omncane ekusebenzeni kahle.

②.Ukuphepha okuhle, ukongiwa kwamanzi kanye nomhlabathi: Nakuba i-diquat inezakhiwo ezithile zesistimu, ngeke ilimaze izimpande zezitshalo, futhi ibulala ukuthintana phela.Ngakho-ke, i-diquat iphinde iqhubeke nezici zokuphepha ze-paraquat ngaphandle kwezinsalela futhi kungekho bungozi bokukhukhuleka.Njengoba utshani besitha bungazibulali izimpande, buyasiza ukongiwa kwamanzi nokongiwa kwenhlabathi, futhi amagquma ensimu akulula ukuwa.

③.Umthelela okhethekile okhulani lwamaqabunga abanzi: I-Diquat inomphumela ongcono wokulawula kune-glufosinate okhulani oluthile olumelana nokhula, ikakhulukazi ukhula lwamaqabunga abanzi.

④.Ukumelana nezinga lokushisa eliphansi: Uma izinga lokushisa lingaphansi kuka-15 ℃, umphumela wokukhipha ukhula uzuzisa kakhulu kune-glufosinate-ammonium.

4. Ungayisebenzisa kanjani i-Diquat ngokuphumelelayo?

①.Ukukhipha ukhula endaweni eyihlane: Enye i-glyphosate ingezwa ngendlela efanele, futhi ukuphindaphinda kokhula esikhathini esizayo kuzoncipha kakhulu.Ngokuqondene nomthamo othize, ungaqala ngokuhlola endaweni encane ngokwezimo zokhula zendawo.

②. Kolunye ukhula oluphethwe i-Gramineae, ungakwazi ukwengeza i-quizalofop, i-clethodim, i-flufenofop, njll.

③.Njengoba i-diquat iwukubulala ngokuyinhloko, lapho ufafaza i-diquat, kufanele ifuthwe kahle futhi ngokulinganayo.Amagciwane anjenge-silicon ephilayo nawo angangezwa ukuze ingaphezulu lokhula lishiye ukuxhumana ngokugcwele futhi limunce i-diquat ukuze kuzuzwe imiphumela engcono.Umphumela omuhle wokubulala ukhula.

④.Uma uhlanza i-diquat, ungasebenzisi amanzi omfula axubile ukuze uvimbele ukuncipha komphumela womuthi.

⑤.Zama ukufaka isibulala-zinambuzane ngemva kokuhwamuka kwamazolo ekuseni.Uma kuvezwa ukukhanya kwelanga emini, umphumela wokuxhumana uzoba sobala futhi umphumela uzoba ngokushesha.(Faka umuthi ebusuku ngaphambi kokuba kube namazolo, ukuze umuthi uzosebenza kahle kakhulu)
