I-Glyphosate ne-Glufosinate, Ama-Herbicides Amabili Aqhathaniswa.

1. Izindlela ezahlukene zokwenza

I-Glyphosateiyi-herbicide ye-biocidal ebanzi ehlelekile, edluliselwa ngaphansi komhlaba ngeziqu namaqabunga.

I-Glufosinate-ammoniumiyi-herbicide yohlobo lwe-conduction engakhethi ye-phosphonic acid. Ngokuvimbela isenzo se-glutamate synthase, i-enzyme ebalulekile yokususa ubuthi ezitshalweni, kuholela ekuphazamisekeni kwe-metabolism ye-nitrogen ezitshalweni, ukuqongelela ngokweqile kwe-ammonium, kanye nokuqhekeka kwama-chloroplast, ngaleyo ndlela kubangele i-photosynthesis yezitshalo. Iyavinjelwa, ekugcineni iholele ekufeni kokhula.

2. Izindlela ezahlukene zokuqhuba

I-Glyphosate iyi-sterilizer yesistimu,

I-Glufosinate iyisibulali sokuxhumana esingahambisani nohlelo noma esibuthakathaka.

3. Umphumela wokukhipha ukhula uhlukile

I-Glyphosate ngokuvamile ithatha izinsuku eziyi-7 kuya kweziyi-10 ukuze isebenze;

I-Glufosinate ngokuvamile ihlala izinsuku ezi-3 (izinga lokushisa elijwayelekile)

Ngokuphathelene nesivinini sokukhipha ukhula, umphumela wokukhipha ukhula, kanye nesikhathi sokuvuselelwa kokhula, ukusebenza kwensimu ye-glufosinate-ammonium kuhle kakhulu. Njengoba ukhula olumelana ne-glyphosate ne-paraquat luba nzima kakhulu, abalimi bazokwazi ukwamukela kalula ngenxa yomphumela walo omuhle wokulawula kanye nokusebenza kahle kwemvelo. Izingadi zetiye, amapulazi, izisekelo zokudla okuluhlaza, njll., ezidinga ukuphepha okwengeziwe kwemvelo, zinesidingo esikhulayo se-glufosinate-ammonium.

4. Uhla lwezinhlobo zokhula luhlukile

I-Glyphosate inomphumela wokulawula ukhula olungaphezu kuka-160, okuhlanganisa nokhula oluyi-monocotyledonous noluyi-dicotyledonous, olukhula minyaka yonke noluhlala isikhathi eside, amakhambi nezihlahla, kodwa ayilungele ukhula oluhlala isikhathi eside oluyingozi.

I-Glufosinate-ammonium iyi-herbicide ebanzi, ebulala ukuthintana, uhlobo lokubulala, engeyona insalela enezinhlobo eziningi zokusetshenziswa. I-Glufosinate ingasetshenziswa kuzo zonke izitshalo (uma nje ingafuthwanga ezitshalweni, kufanele kufakwe isembozo sokufutha phakathi kwemigqa). noma i-hood). Kusetshenziswa ukwelashwa kwe-spray yesiqu sokhula kanye neqabunga, ingasetshenziswa cishe ukulawula ukhula lwezihlahla zezithelo ezitshalwe kabanzi, izitshalo zemigqa, imifino kanye nomhlaba ongalinywa; ingabulala ngokushesha izinhlobo ezingaphezu kwe-100 zotshani kanye nokhula olunamaqabunga abanzi, ikakhulukazi Inomthelela omuhle kakhulu kokhula oluthile oluyingozi olumelana ne-glyphosate, njengotshani lwe-beef tendon, i-purslane, kanye ne-small fly, futhi isibe yisitha sotshani kanye nokhula olunamaqabunga abanzi.

5. Ukusebenza okuhlukile kokuphepha

I-Glyphosate ngokuvamile ihlwanyelwa futhi itshalwe kabusha ezinsukwini eziyi-15-25 ngemuva kokusebenza kahle komuthi, ngaphandle kwalokho ithambekele ekubeni nobuthi be-phytotoxicity; i-glyphosate iyi-herbicide ebulala amagciwane. Ukusetshenziswa okungalungile kuzoletha izingozi zokuphepha ezitshalweni, ikakhulukazi ukuyisebenzisa ukulawula ukhula eziqongweni noma ezivandeni zezithelo. Uma kwenzeka ukulimala kokukhukhuleka, kungenzeka kakhulu. Kufanele kugcizelelwe ukuthi i-glyphosate ingaholela kalula ekushodeni kwezinto ezilandelwayo enhlabathini, yakhe ukuntuleka kwezakhamzimba, futhi yonakalise uhlelo lwezimpande. Ukusetshenziswa kwesikhathi eside kuzoholela ekuphuzeni kwezihlahla zezithelo.

I-Glufosinate ingahlwanyelwa futhi itshalwe kabusha ezinsukwini ezi-2 kuya kwezi-4. I-Glufosinate-ammonium ayinabo ubuthi obuphansi, iphephile, iyashesha, inobungani nemvelo, i-top dressing yandisa umkhiqizo, ayinawo umthelela enhlabathini, ezimpandeni zezitshalo nasezitshalweni ezilandelayo, futhi inomphumela ohlala isikhathi eside. Ukukhukhuleka kufaneleke kakhulu ekukhuculeni ukhula kummbila, ilayisi, ubhontshisi, izingadi zetiye, izivande zezithelo, njll., okungenakugwenywa ngokuphelele ngezikhathi ezibucayi noma ukukhukhuleka kwamaconsi.

6. Ikusasa

Inkinga eyinhloko ebhekene ne-glyphosate ukumelana nemithi. Ngenxa yezinzuzo zokusebenza kahle kwe-glyphosate, ama-yuan angu-5-10/mu (izindleko eziphansi), kanye nokusetshenziswa kwe-metabolism okusheshayo komuntu, i-glyphosate isenendlela ende okufanele iyihambe ngaphambi kokuba iqedwe ngokukhululekile yimakethe. Ngenxa yenkinga yokumelana ne-glyphosate, ukusetshenziswa okuxubile kwamanje kuyindlela enhle yokulwa nayo.

Ithuba lemakethe le-glufosinate-ammonium lihle futhi ukukhula kuyashesha, kodwa ubunzima bobuchwepheshe bokukhiqizwa komkhiqizo buphezulu, futhi indlela yenqubo nayo iyinkimbinkimbi. Zimbalwa kakhulu izinkampani zasekhaya ezingakhiqiza ngezinga elikhulu. Isazi sokhula uLiu Changling sikholelwa ukuthi i-glufosinate ayikwazi ukunqoba i-glyphosate. Uma sibheka izindleko, i-10~15 yuan/mu (izindleko eziphakeme), intengo yethani le-glyphosate icishe ibe ngu-20,000, kanti intengo yethani le-glufosinate icishe ibe ngu-20,000 yuan. 150,000 - ukukhuthazwa kwe-glufosinate-ammonium, igebe lentengo liyigebe elingenakuvalwa.
