一, iimpawu zothintelo olomileyo
Iarhente yokumisa eyomileyo luhlobo lwemveliso yokuqulunqwa kwempahla yokubulala izitshabalalisi. Yimveliso entsha yemveliso engcono kunezinye iindlela ngokomxholo, ukupakisha, itekhnoloji, iindleko, uzinzo lomgangatho, kunye netekhnoloji yesicelo emva kwe-arhente yokumisa iarhente emva kwe-Arhente yokuHamba. Intsebenzo yayo iyenza ibe yimveliso ephezulu kwi-granules ezisasazeke zamanzi. Kuba iarhente yokumisa eyomileyo ikwimeko yokumiswa ngaphambi komomo kwaye i-granselting, iba yimeko yamasuntswana aqinileyo emva kokutshisa nokwahlula; Xa isetyenziswa, ichithwe ngamanzi kwaye ibuyiselwe kwimo yokunqunyanyiswa, kwaye amasuntswana aqingqiweyo anezitshabalalo ye-1-10 μm asetyenziswa njengesigaba sokusasazeka, inkqubo yokusasazeka ngamanzi njengenqanaba elisebenzayo. Emva komile, iba yindawo eqinileyo ye-paricle, kwaye xa isetyenziswa ngamanzi, ibuyela kwimeko yokumiswa. Umgangatho wayo wangaphakathi unazo zonke izibonelelo zearhente yokumiswa, kwaye iipropathi zayo ezisemzimbeni zilungile. Umsebenzi othile ngolu hlobo lulandelayo:
1. Iyahlulelana ngokukhawuleza emanzini, ineentsali ezifanelekileyo kunye nokumiswa. Iyahluma ngoko nangoko emanzini, isasazi kwi-6 s ukuya kwi-10 s, kwaye ikhawuleza inqunyanyisiwe, ngaphandle kokunyanzelwa, akukho sidingo, kwaye akukho sidingo sokuthintela i-nozzle.
2. Yongeza inani elincinci lamanzi ukuze usebenzise umnyhawulo mveliso, onokuthi asetyenziswe ngokuthe ngqo kwinqwelomoya okanye kumhlaba wesitshizi. Isixa esincinci sokutshiza sinokwandisa ukusebenza ngokutsha komsebenzi ngamaxesha ali-10, kwaye ukusebenza kakuhle komsebenzi kuphantse kuphantse kube likhulu kuneso sesona sitshizi siqhelekileyo.
3. Amasuntswana eendlela zonyango lwemveliso zilungile ngokwaneleyo ukuba zilandele ngqo kumphezulu wesityalo emva kokutshiza, ukwenza ifilimu ekhuselayo; Ixhaswe ngumlinganiso otyhafileyo otyhalela iarhente, inokuphucula ukusebenza komthendeleko kunye nokuxhathisa ukhukuliseko lwemvula. Ngokubanzi, ixesha elingapheliyo le-fungficides ziintsuku ezingama-5-7, kodwa emva kokwamkela ifom yokumiswa eyomileyo, ixesha elingapheliyo linokwandiswa kwiintsuku ezili-10 ukuya kwezi-4.
I-4. Ubungakanani be-suricle yokusasazwa kwamayeza olwelo lwemveliso bungangqinelani, nto leyo engenakuqiniseka ukuba nefuthe lokusebenza ngokukhawuleza kunye nendlela ehlala ihleli yeyeza, kodwa ikwanokuqinisekisa ukuba iyeza linokunxibelelana ngokupheleleyo kwaye liphumelele iyeza isiphumo.
5. Ukhuseleko oluhle, ngokungafaniyo nemigubo ehlekisayo, amasuntswana amakhulu aya kwenza ugxininiso oluphezulu lwengingqi kumphezulu wesityalo kwaye ubangele i-phytootocity. Ingasetyenziswa nakwixesha lentyatyambo, njenge-80% ye-fulfur DF. Ngenxa yokusetyenziswa kolu lwakhiwo luphezulu, kunokunika iMidlalo epheleleyo kwiingenelo zemveliso ekukhuseleni nasekusebenzeni ngokufanelekileyo ngexesha lokusetyenziswa. Ingasetyenziselwa ngaphezulu kokumiswa kwe-sulfur kunye ne-sulfur powder. Ngothintelo kunye nonyango lwe-powdery daildew kunye neemitha ezahlukeneyo eziyingozi, inani lesityalo lincinci kodwa isiphumo silungile kakhulu.
6. Ukhuseleko olukhuselekileyo neliyisigaba lokuziphatha, musa ukubangela izinyibilikisi eziphilayo, akuyi kubangela iingxaki zokungcoliseka zeSolvent, akukho tshintsho, lukhuselekile kubasebenzisi, kwaye unokuthintela iingxaki ze-phytotootocity ezibangelwa kukuhamba kwenkunkuma.
7. Akukho luthuli, akukho ndinamathela kwingxowa yokupakisha, isetyenziswe ngokupheleleyo, kwaye ikhuselekile kumqhubi kunye nendawo engqongileyo.
I-8. Emva kwemveliso eyomileyo yokuziqhelanisa igxilwe ngamanzi, ubungakanani be-suricle yesuntsu zeheketini kulungile, kulula ukudlala indima kwithagethi kwaye kunempumelelo ephezulu.
9. Zimbini iindlela zokusebenzisa iimveliso ezomileyo zokumiswa: Enye yeyona nto isetyenziswayo, imveliso ichithwe ngamanzi (ukunqunyanyiswa) kwaye emva koko ifakwe kwiziqu kunye namagqabi; Omnye kukudibanisa imveliso yokumiswa eyomileyo ngomhlaba kunye nokusasazeka (njenge-paddy prebicides).
二. Umgaqo we-granang rating yearhente yokumiselwa
Kukho iimeko ezimbini eziyimfuneko zokusebenza okwenzayo: enye kukusebenzisa i-gesing yesanti emanzi (okt ukulungisa itekhnoloji yokulungiselela ukumiswa komgangatho we-1-10μm; enye kukusebenzisa itekhnoloji yokutshiza, imveliso ye-DF ifunyanwa ngokuthe ngqo emva kokususa amanzi kunye nokuhlala; Ingaphakathi lemveliso ye-DF yindawo emngxunyeni, incinci, iyunifomu ye-Pellet ene-Pellet ibe yi-50-200 μm, encinci kuneyona ndlela ifunyenweyo. Imveliso ye-DF inexesha elifutshane lokungasebenziyo emanzini, kwaye ichithwa ngokubanzi kwilifu. Ingahlala isasazeka ngokuzenzekelayo ngaphakathi kwe-10 s ukwenza ukumiswa kobungakanani boqobo. Izinga lokumiswa liphezulu, kwaye izikhombisi zalo ezahlukeneyo zingcono kunezinye iindlela zoqhako. Iimveliso ze-WG.
