Izici kanye nomgomo we-granution wekwakhiwa kwe-DF

一, izici zokumiswa okwomile

I-ejenti esomile eyomile uhlobo lomkhiqizo wokubulala izinambuzane. Kungumkhiqizo wesizukulwane omusha ongcono kakhulu kunezinye izindlela ngokuya ngokuqukethwe, ukupakisha, ubuchwepheshe, izindleko, ukuqina kwekhwalithi, ubuchwepheshe bohlelo lokusebenza ngemuva kokumiswa kwe-ejenti. Ukusebenza kwayo kwenza kube ngumkhiqizo ophezulu kuma-granule ahluke amanzi. Ngoba i-ejenti esomile esomile isesimweni sokumiswa ngaphambi kokomiswa nokugaya, iba yisimo sezinhlayiya eziqinile ngemuva kokomiswa kokufafaza nokuthambekela; Uma isetshenziswa, ihlanganiswe namanzi bese ibuyela esimweni sokumiswa, kanye nezinhlayiya eziqinile zokubulala izinambuzane ngosayizi wezinhlayiyana ze-1-10 μm zisetshenziswa njengesigaba sokusakazeka, uhlelo lokuhlakazeka olunamanzi njengesigaba esiqhubekayo. Ngemuva kokumiswa, kuba yisimo esiqinile sezinhlayiyana, futhi lapho isetshenziswa ngamanzi, ibuyela esimweni sokumiswa. Ikhwalithi yayo yangaphakathi inazo zonke izinzuzo ze-ejenti yokumiswa, futhi izakhiwo zalo ezibonakalayo zihle kakhulu. Ukusebenza okuthize kungokulandelayo:

1. Ihlukanisa ngokushesha emanzini, inokusiza okuhle nokumiswa. Ihlukanisa ngokushesha emanzini, isaphuphuthekile ku-6 s kuya ku-10 s, futhi ngokushesha yakha ukumiswa okuzinzile, ngaphandle kwemvula, akukho okunamandla, futhi asikho isidingo sokuvimba ama-nozzle.

2. Faka inani elincane lamanzi ukuze unciphise ukumiswa komkhiqizo, okungasetshenziswa ngqo ngendiza noma emhlabathini i-micro-fafaza. Inani elincane lesifutho lingakhulisa ukusebenza kahle komsebenzi amahlandla ayi-10, futhi ukusebenza kahle komsebenzi kucishe kuphakame kakhulu kunokubalwa.

I-3. Izinhlayiya zomuthi owuketshezi zilungile ngokwanele ukuba zilandele ngokulinganayo ebusweni besitshalo ngemuva kokufafaza, bakha ifilimu ebumnene; Ingezelelwa nge-ejenti yokusakazeka okuhle, ingathuthukisa ukusebenza kokunamathela futhi imelane nokuguguleka kwemvula. Ngokuvamile, isikhathi esigcina se-fungicides izinsuku ezingama-5-7, kodwa ngemuva kokuthola ifomu lokumiswa eyomile, isikhathi esigcina seludluliselwe ezinsukwini eziyi-10-16.

I-4. Ukusatshalaliswa kosayizi wezinhlayiyana komuthi we-proodwork kunengqondo, okungakwazi ukuqinisekisa kuphela umphumela osebenza ngokusheshe nomuthi, kepha futhi uqinisekise ukuthi umuthi ungaxhumana ngokuphelele futhi uxhumana ngokuphelele nomuthi wesilimo ukuze uthuthukise umuthi umphumela.

I-5. Ukuphepha okuhle, ngokungafani namapopi athile angenakuphikwa, izinhlayiya ezinkulu zizokwakha ukugxila okuphezulu kwendawo ebusweni besitshalo futhi kubangele i-phytotoxity. Ingasetshenziswa ngisho nangesikhathi sezimbali, njenge-80% sulfur df. Ngenxa yokusetshenziswa kwalokhu kusungulwa okuthuthukile, kunganikeza ukudlala okugcwele ezinhlelweni zomkhiqizo ngokuphepha kanye nokusebenza kahle ngesikhathi sokusetshenziswa. Ingasetshenziswa ngaphezu kokumiswa kwesibabule kanye ne-sulfur powder. Ekuvinjweni kanye nokwelashwa kwe-powdery isikhutha kanye nezibungu ezahlukahlukene ezilimazayo, inani lesilimo lincane kepha umphumela muhle kakhulu.

I-6 Ukwakheka okuphephile nangokwemvelo, ungasebenzisi noma yiziphi izixazululo ze-organic, ngeke kubangele izinkinga zokungcola kwe-solvent, alukho uthuli, oluphephile lwabasebenzisi, futhi lungagwema nezinkinga ze-phytotoxity ezibangelwa yi-ejenti Drift.

7. Alukho uthuli, akukho okunamathelayo esikhwameni sokupakisha, kusetshenziswe ngokuphelele, futhi kuphephe kakhulu opharetha kanye nendawo ezungezile.

9. Kunezindlela ezimbili zokusebenzisa imikhiqizo yokumiswa eyomile: eyodwa isetshenziswa kakhulu, umkhiqizo uvinjelwe ngamanzi (ekumisweni) bese ufafazwa ezihlahleni nasemaqabungeni; Okunye ukuxuba umkhiqizo wokumiswa owomile ngenhlabathi nokusakazeka (njenge-paddy field herbicides).

二. Umgomo we-granution we-ejenti yokumiswa okomile

Kunezimo ezimbili ezidingekayo zokucutshungulwa kokumiswa okusomile: Eyokuqala ukusebenzisa ubuchwepheshe besihlabathi esimanzi (ie sc) ubuchwepheshe ukulungiselela ukumiswa ngosayizi ophakathi kwezinhlayiyana we-1-10μm; Enye ukusebenzisa ubuchwepheshe be-Spray Corying Granution, umkhiqizo we-DF utholakale ngqo ngemuva kokususa amanzi nokuvinjwa; Ingaphakathi lomkhiqizo we-DF liyi-hollow, encane, eyunifomu yomkhiqizo we-pellet nge-pellet yobubanzi be-50-200 μm, elincane kunalokho okutholwe ezinye izindlela ze-granution. Umkhiqizo we-DF unesikhathi esifushane sokuqhekeka emanzini, futhi ngokuvamile uhlakazwa ngesimo samafu. Imvamisa ihlakazeke ngokuzenzakalela ngaphakathi kwama-10 s ukwakha ukumiswa kosayizi wokuqala wezinhlayiyana. Izinga lokumiswa liphezulu, futhi izinkomba zalo ezahlukahlukene zingcono kunezinye izindlela ezomile ze-granun. Imikhiqizo ye-WG.
