I-Glyphosate kunye neGlufosinate, ii-Herbicides ezimbini xa zithelekiswa.

1. Iindlela ezahlukeneyo zokwenza

I-Glyphosate sisichiza esisistim esibanzi se-biocidal, esigqithiselwa ngaphantsi komhlaba ngeziqu kunye namagqabi.

I-Glufosinate-ammonium i-non-selective conduction type herbicide ye-phosphonic acid. Ngokuthintela isenzo se-glutamate synthase, i-enzyme ebalulekileyo ye-detoxification yezityalo, ikhokelela ekuphazamisekeni kwe-nitrogen metabolism kwizityalo, ukuqokelela ngokugqithiseleyo kwe-ammonium, kunye nokuchithwa kwe-chloroplasts, ngaloo ndlela kubangele i-photosynthesis yezityalo. Ithintelwe, ekugqibeleni ikhokelela ekufeni kokhula.

2. Iindlela zokuqhuba ezahlukeneyo

I-Glyphosate sisicoci senkqubo ye-sterilizer,

I-Glufosinate ngumbulali we-semi-systemic okanye obuthathaka ongasebenziyo.

3. Isiphumo sokukhula sahlukile

I-Glyphosate ngokubanzi ithatha i-7 kwiintsuku ze-10 ukuba isebenze;

IGlufosinate iba ziintsuku ezi-3 (ubushushu obuqhelekileyo)

Ngokumalunga nesantya sokukhula, isiphumo sokukhula, kunye nexesha lokuvuselela ukhula, ukusebenza kwentsimi ye-glufosinate-ammonium kuhle kakhulu. Njengoko ukhula oluxhathisayo lweglyphosate kunye neparaquat lusiya lusiba nzima, abalimi baya kuyamkela lula ngenxa yempembelelo yayo ebalaseleyo yolawulo kunye nokusebenza kakuhle kokusingqongileyo. Izitiya zeti, iifama, iziseko zokutya okuluhlaza, njl., ezifuna ukhuseleko oluthe kratya lwendalo, zinemfuno eyandayo ye-glufosinate-ammonium.

4. Uluhlu lokukhula luhlukile

I-Glyphosate inempembelelo yokulawula ngaphezu kwe-160 yokhula, kubandakanywa i-monocotyledonous kunye ne-dicotyledonous, yonyaka kunye ne-perennial, imifuno kunye nezihlahla, kodwa ayifanelekanga ukhula olubi olungapheliyo.

I-Glufosinate-ammonium yi-spectrum ebanzi, i-contact-killing, ukubulala-uhlobo, i-herbicide engashiyekiyo kunye noluhlu olubanzi lwezicelo. IGlufosinate ingasetyenziswa kuzo zonke izityalo (ukuba nje ingatshizwanga kwizityalo, kufuneka kufakwe isigqubuthelo sokutshiza phakathi kwemiqolo). okanye ihood). Ngokusebenzisa isiqu sokhula kunye nonyango lokutshiza oluya kwicala legqabi, luphantse lusetyenziswe ekutshatyalalisweni kokhula lwemithi yeziqhamo etyalwe ngokubanzi, izityalo ezikroliweyo, imifuno kunye nomhlaba ongalinywayo; inokubulala ngokukhawuleza ngaphezu kweendidi ze-100 zengca kunye nokhula olunamaqabunga abanzi, ngakumbi Unefuthe elihle kakhulu kukhula olubi oluchasene ne-glyphosate, njengengca ye-tendon yenkomo, i-purslane, kunye nempukane encinci, kwaye iye yaba yintshaba. yengca kunye nokhula olunamagqabi abanzi.

5. Ukusebenza kokhuseleko okwahlukileyo

I-Glyphosate ngokuqhelekileyo ihlwayelwa kwaye ifakwe emva kweentsuku ze-15-25 emva kokusebenza kweyeza, ngaphandle koko ixhomekeke kwi-phytotoxicity; I-glyphosate sisichiza esibulala ukhula. Ukusetyenziswa okungafanelekanga kuya kuzisa iingozi zokhuseleko kwizityalo, ngakumbi ukuzisebenzisa ukulawula ukhula kwimiqolomba okanye kwintsimi yeziqhamo Xa , ukwenzakala kwe-drift kunokwenzeka ukuba kwenzeke. Kufuneka kugxininiswe ukuba i-glyphosate inokukhokelela ngokulula ekunqongopheni kwezinto zokulandelela emhlabeni, ukwenza ukusilela kwezondlo, kwaye konakalise inkqubo yeengcambu. Ukusetyenziswa kwexesha elide kuya kukhokelela ekubeni imithi yeziqhamo ibe tyheli.

I-Glufosinate inokuhlwayelwa kwaye ifakwe kwiintsuku ezi-2 ukuya kwezi-4. I-Glufosinate-ammonium inetyhefu ephantsi, ikhuselekile, iyakhawuleza, ihambelana nokusingqongileyo, ukunxitywa okuphezulu kwandisa imveliso, akukho mpembelelo kumhlaba, iingcambu zezityalo kunye nezityalo ezilandelayo, kwaye zinefuthe elide elide. I-Drift ifaneleke ngakumbi ukuhlakula kumbona, irayisi, iimbotyi zesoya, izitiya zeti, igadi yeziqhamo, njl.

6. Ikamva

Eyona ngxaki iphambili ejongene ne-glyphosate kukunganyangeki ngamachiza. Ngenxa yeenzuzo zokusebenza okuphezulu kwe-glyphosate, i-5-10 yuan / mu (ixabiso eliphantsi), kunye ne-metabolism yabantu ngokukhawuleza, i-glyphosate inendlela ende yokuhamba ngaphambi kokuba ikhutshwe ngokukhululekile yimarike. Ngenxa yengxaki yokumelana ne-glyphosate, ukusetyenziswa okuxutywayo kwangoku kukuchasana okulungileyo.

Ithemba lemarike ye-glufosinate-ammonium lilungile kwaye ukukhula ngokukhawuleza, kodwa ubunzima bobugcisa bokuvelisa imveliso buphezulu, kwaye indlela yenkqubo nayo inzima. Zimbalwa kakhulu iinkampani zasekhaya ezinokuvelisa ngomlinganiselo omkhulu. Ingcaphephe yokhula uLiu Changling ukholelwa ukuba iglufosinate ayinakoyisa iglyphosate. Ukuqwalasela iindleko, i-10 ~ 15 yuan / mu (iindleko eziphezulu), ixabiso letoni ye-glyphosate li malunga ne-20,000, kwaye ixabiso letoni ye-glufosinate malunga ne-20,000 yuan. I-150,000 - ukukhuthazwa kwe-glufosinate-ammonium, i-gap yexabiso yi-gap engenakunqandwa.
