I-Glyphosate ne-Glufosinate, Ama-Herbicides amabili aqhathaniswa.

1. Izindlela ezehlukene zokwenza

I-Glyphosate iyi-systemic broad-spectrum biocidal herbicide, edluliselwa ngaphansi komhlaba ngeziqu namaqabunga.

I-Glufosinate-ammonium iyi-herbicide engakhethi yohlobo lwe-phosphonic acid. Ngokuvimbela isenzo se-glutamate synthase, i-enzyme ebalulekile yokukhipha ubuthi ezitshalweni, kuholela ekuphazamisekeni kwe-nitrogen metabolism ezitshalweni, ukunqwabelana ngokweqile kwe-ammonium, nokuhlakazeka kwama-chloroplast, ngaleyo ndlela kubangele i-photosynthesis yezitshalo. Ivinjiwe, ekugcineni iholele ekufeni kokhula.

2. Izindlela zokuqhuba ezihlukene

I-Glyphosate iyi-systemic sterilizer,

I-Glufosinate ingumbulali wokuxhumana we-semi-systemic noma obuthakathaka ongaqhubeki.

3. Umphumela we-weeding uhlukile

I-Glyphosate ngokuvamile ithatha izinsuku ezingu-7 kuya kweziyi-10 ukuze iqale ukusebenza;

I-Glufosinate ngokuvamile iyizinsuku ezi-3 (izinga lokushisa elivamile)

Mayelana nesivinini sokukhula, umphumela wokukhipha ukhula, nesikhathi sokuvuselela ukhula, ukusebenza kwensimu ye-glufosinate-ammonium kuhle kakhulu. Njengoba ukhula olungazweli lwe-glyphosate kanye ne-paraquat luba lubi nakakhulu, abalimi bayokwamukela Kulula ukwamukela ngenxa yomphumela walo omuhle kakhulu wokulawula nokusebenza kahle kwemvelo. Izingadi zetiye, amapulazi, izisekelo zokudla okuluhlaza, njll., ezidinga ukuphepha okwengeziwe kwemvelo, zinesidingo esikhulayo se-glufosinate-ammonium.

4. Uhla lokukhula luhlukile

I-Glyphosate inomphumela wokulawula ukhula olungaphezu kuka-160, okuhlanganisa i-monocotyledonous kanye ne-dicotyledonous, yonyaka kanye ne-perennial, amakhambi nezihlahla, kodwa ayilungele ukhula oluyingozi olungapheli.

I-Glufosinate-ammonium iyi-spectrum ebanzi, ebulala ukuthintana, uhlobo lokubulala, lokubulala ukhula olungasali nolubanzi olusetshenziswayo. IGlufosinate ingasetshenziswa kuzo zonke izitshalo (inqobo nje uma ingafuthwanga ezitshalweni, kufanele kufakwe isembozo sokufafaza phakathi kwemigqa). noma i-hood). Ngokusebenzisa isiqu sokhula kanye nokwelapha isifutho esiqondisa amaqabunga, singacishe sisetshenziselwe ukulawula ukhula lwezihlahla zezithelo ezitshalwe kabanzi, izitshalo ezilandelanayo, imifino kanye nomhlabathi ongalimeki; ingabulala ngokushesha izinhlobo ezingaphezu kweziyi-100 zotshani nokhula olunamaqabunga abanzi, ikakhulukazi Inomphumela omuhle kakhulu kolunye ukhula oluyingozi olumelana ne-glyphosate, njengotshani bethambo lenkomo, i-purslane, nempukane encane, futhi isiphenduke izitha. zotshani nokhula olunamaqabunga abanzi.

5. Ukusebenza okuhlukile kokuphepha

I-Glyphosate ivame ukuhlwanyelwa futhi itshalwe kabusha ezinsukwini ezingu-15-25 ngemva kokusebenza komuthi, ngaphandle kwalokho ithambekele ku-phytotoxicity; I-glyphosate iyi-biocidal herbicide. Ukusetshenziswa okungalungile kuzoletha izingozi zokuphepha ezitshalweni, ikakhulukazi ukuyisebenzisela ukulawula ukhula emagqumeni noma ezinsimini zezithelo Lapho , ukulimala kokukhukhuleka kungenzeka kakhulu. Kufanele kugcizelelwe ukuthi i-glyphosate ingaholela kalula ekuntulekeni kwezakhi zokulandelela emhlabathini, yakha ukuntuleka kwezakhi, futhi ilimaze uhlelo lwezimpande. Ukusetshenziswa isikhathi eside kuzoholela ekutheni izihlahla zezithelo zibe phuzi.

I-Glufosinate ingahlwanyelwa futhi itshalwe kabusha ezinsukwini ezi-2 kuye kwezi-4. I-Glufosinate-ammonium inobuthi obuphansi, iphephile, iyashesha, ayihambisani nemvelo, ukugqoka okuphezulu kwandisa ukukhiqizwa, akunawo umthelela emhlabathini, ezimpandeni zezitshalo nasezitshalweni ezilandelayo, futhi kunomphumela ohlala isikhathi eside. I-Drift ifaneleka kakhulu ukuhlakula emmbila, irayisi, ubhontshisi wesoya, izingadi zetiye, amasimu ezithelo, njll., okungenakugwenywa ngokuphelele ngezikhathi ezibucayi noma ukukhukhuleka kwamaconsi.

6. Ikusasa

Inkinga esemqoka ebhekene ne-glyphosate ukumelana nezidakamizwa. Ngenxa yezinzuzo zokusebenza kahle okuphezulu kwe-glyphosate, i-5-10 yuan/mu (izindleko eziphansi), kanye ne-metabolism yomuntu esheshayo, i-glyphosate inendlela ende okufanele ihambe ngaphambi kokuthi iqedwe ngokukhululeka yimakethe. Uma kubhekwa inkinga yokumelana ne-glyphosate, ukusetshenziswa kwamanje okuxubile kuyisinyathelo esihle sokuphikisana.

Ithemba lemakethe le-glufosinate-ammonium lihle futhi ukukhula kuyashesha, kodwa ubunzima bezobuchwepheshe bokukhiqiza umkhiqizo buphezulu, futhi umzila wenqubo nawo uyinkimbinkimbi. Zimbalwa kakhulu izinkampani zasekhaya ezingakhiqiza ngezinga elikhulu. Uchwepheshe wokhula uLiu Changling ukholelwa ukuthi i-glufosinate ayikwazi ukunqoba i-glyphosate. Uma kucatshangelwa izindleko, i-10 ~ 15 yuan/mu (izindleko eziphezulu), intengo yethani le-glyphosate cishe i-20,000, futhi intengo yethani le-glufosinate cishe i-20,000 yuan. 150,000 - ukukhuthazwa kwe-glufosinate-ammonium, igebe lentengo liyigebe elingenakuvinjwa.
