I-Glyphosate kunye ne-Glufosinate, ii-Herbicides ezimbini ezithelekiswayo.

1. Iindlela ezahlukeneyo zokwenza izinto

I-Glyphosatesisibulali-zinambuzane esibizwa ngokuba yi-systemic broad-spectrum biocidal herbicide, esidluliselwa phantsi komhlaba ngeziqu namagqabi.

I-Glufosinate-ammoniumyi-herbicide yohlobo lwe-phosphonic acid engakhethiyo. Ngokuthintela ukusebenza kwe-glutamate synthase, i-enzyme ebalulekileyo yokukhupha ubuthi kwizityalo, ikhokelela ekuphazamisekeni kwe-nitrogen metabolism kwizityalo, ukuqokelelana kakhulu kwe-ammonium, kunye nokuqhekeka kwe-chloroplast, ngaloo ndlela kubangele i-photosynthesis yezityalo. Iyathintelwa, ekugqibeleni ikhokelela ekufeni kokhula.

2. Iindlela ezahlukeneyo zokuqhuba

IGlyphosate sisibulali-ntsholongwane esisebenza ngokwenkqubo,

I-Glufosinate yi-contact killer engasebenzi kakuhle okanye engakwaziyo ukukhupha umoya.

3. Isiphumo sokukhuhla ukhula sahlukile

IGlyphosate idla ngokuthatha iintsuku ezisi-7 ukuya kwezili-10 ukuze isebenze;

I-Glufosinate ihlala iintsuku ezi-3 (ubushushu obuqhelekileyo)

Ngokuphathelele isantya sokukhula, isiphumo sokukhula, kunye nexesha lokuvuselelwa kokhula, ukusebenza kwentsimi ye-glufosinate-ammonium kugqwesile. Njengoko ukhula oluxhathisayo lwe-glyphosate kunye ne-paraquat lusiba nzima ngakumbi, abalimi baya kwamkela ngokulula ngenxa yesiphumo salo sokulawula esibalaseleyo kunye nokusebenza kakuhle kokusingqongileyo. Iigadi zeti, iifama, iziseko zokutya eziluhlaza, njl.njl., ezifuna ukhuseleko olungakumbi kwindalo, zifuna i-glufosinate-ammonium ngakumbi.

4. Uluhlu lokukhuhla ukhula lwahlukile

I-Glyphosate inefuthe lokulawula ukhula olungaphezulu kwe-160, kuquka i-monocotyledonous kunye ne-dicotyledonous, i-annual kunye ne-perennial, imifuno kunye nezihlahla, kodwa ayilungele ezinye ukhula olunobungozi oluhlala luhleli.

I-Glufosinate-ammonium sisibulali-zinambuzane esibanzi, esibulala abantu, esibulala abantu, esingesiso intsalela esinokusetyenziswa ngeendlela ezahlukeneyo. I-Glufosinate ingasetyenziswa kuzo zonke izityalo (ukuba nje ayitshizwanga kwizityalo, kufuneka kongezwe isigqubuthelo sokutshiza phakathi kwemiqolo). okanye i-hood). Isebenzisa unyango lokutshiza oluvela kwisiqu sokhula kunye namagqabi, ingasetyenziselwa phantse ukulawula ukhula kwimithi yeziqhamo etyalwe ngokubanzi, izityalo ezityalwe emiqolo, imifuno kunye nomhlaba ongalinywayo; inokubulala ngokukhawuleza iintlobo ezingaphezu kwe-100 zengca kunye nokhula olunamagqabi abanzi, ngakumbi. Inefuthe elihle kakhulu kolunye ukhula olunobungozi olumelana ne-glyphosate, olufana ne-beef tendon grass, i-purslane, kunye ne-small fly, kwaye ibe yintshaba yengca kunye nokhula olunamagqabi abanzi.

5. Ukusebenza okwahlukileyo kokhuseleko

I-Glyphosate idla ngokuhlwayelwa ize ityalwe emva kweentsuku ezili-15-25 emva kokusebenza kakuhle kwesi sithako, kungenjalo inokuba yingozi kwizityalo; i-glyphosate sisibulali-zinambuzane esibangela iintsholongwane. Ukusetyenziswa ngendlela engafanelekanga kuya kuzisa iingozi zokhuseleko kwizityalo, ingakumbi ukuyisebenzisa ukulawula ukhula kwiinduli okanye kwiigadi zeziqhamo. Xa , ukulimala kokukhukuliseka kunokwenzeka kakhulu. Kufuneka kugxininiswe ukuba i-glyphosate inokukhokelela ngokulula ekuswelekeni kwezinto ezilandelelanayo emhlabeni, yenze ukungabikho kwezondlo, kwaye yonakalise inkqubo yeengcambu. Ukusetyenziswa ixesha elide kuya kukhokelela ekubeni imithi yeziqhamo ibe tyheli.

I-Glufosinate ingahlwayelwa ize ityalwe kwakhona kwiintsuku ezi-2 ukuya kwezi-4. I-Glufosinate-ammonium ayinabungozi kangako, ikhuselekile, iyakhawuleza, inobuhlobo nokusingqongileyo, i-top dressing inyusa imveliso, ayinampembelelo emhlabeni, kwiingcambu zezityalo nakwizityalo ezilandelayo, kwaye inempembelelo ehlala ixesha elide. I-Drift ifanelekile ngakumbi ekukhuliseni ukhula embona, erayisini, kwiimbotyi zesoya, kwiigadi zeti, kwiigadi zeziqhamo, njl.njl., ezingenakuthinjwa ngokupheleleyo ngexesha lobuthathaka okanye ukukhukhuleka kwamaconsi.

6. Ikamva

Ingxaki ephambili ejongene ne-glyphosate kukunganyamezelani namayeza. Ngenxa yeenzuzo zokusebenza kakuhle kwe-glyphosate, i-5-10 yuan/mu (ixabiso eliphantsi), kunye ne-metabolism ekhawulezayo yomntu, i-glyphosate inendlela ende ekufuneka ihambe ngaphambi kokuba isuswe ngokukhululekileyo yimarike. Ngenxa yengxaki yokunganyamezelani ne-glyphosate, ukusetyenziswa okuxutyiweyo kwangoku yindlela elungileyo yokulwa.

Ithemba lemarike le-glufosinate-ammonium lilungile kwaye ukukhula kuyakhawuleza, kodwa ubunzima bobuchwephesha bokuveliswa kwemveliso buphezulu, kwaye nendlela yenkqubo nayo iyinkimbinkimbi. Zimbalwa kakhulu iinkampani zasekhaya ezinokuvelisa ngomlinganiselo omkhulu. Ingcali yokhula uLiu Changling ikholelwa ukuba i-glufosinate ayinakoyisa i-glyphosate. Xa ucinga ngexabiso, i-10~15 yuan/mu (ixabiso eliphezulu), ixabiso letoni ye-glyphosate limalunga nama-20,000, kwaye ixabiso letoni ye-glufosinate limalunga nama-20,000 yuan. I-150,000 - ukukhuthazwa kwe-glufosinate-ammonium, umsantsa wamaxabiso ngumsantsa ongenakuvalwa.
