1. Njira zosiyanasiyana
Glyphosate ndi systemic wide-spectrum biocidal herbicide, yomwe imafalikira kunsi kwa nthaka kudzera mumitengo ndi masamba.
Glufosinate-ammonium ndi mankhwala osasankha amtundu wa phosphonic acid. Mwa kuletsa zochita za glutamate synthase, yofunika detoxification enzyme ya zomera, kumabweretsa chisokonezo cha nayitrogeni kagayidwe mu zomera, kwambiri kudzikundikira ammonium, ndi azingokhala chloroplasts, potero kuchititsa zomera photosynthesis. Zoletsedwa, pamapeto pake zimatsogolera ku imfa ya namsongole.
2. Njira zosiyanasiyana zoyendetsera
Glyphosate ndi systemic sterilizer,
Glufosinate ndi wakupha wa semi-systemic kapena wofooka wopanda conductive.
3. Kupalira zotsatira ndizosiyana
Glyphosate nthawi zambiri imatenga masiku 7 mpaka 10 kuti igwire ntchito;
Glufosinate nthawi zambiri imakhala masiku atatu (kutentha kwabwinobwino)
Pankhani ya liwiro la Kupalira, Kupalira, ndi nthawi yokonzanso udzu, ntchito yamunda ya glufosinate-ammonium ndiyabwino kwambiri. Pamene udzu wosamva wa glyphosate ndi paraquat ukuchulukirachulukira, alimi amatero N'zosavuta kuvomereza chifukwa cha mphamvu zake zowongolera bwino komanso magwiridwe antchito abwino a chilengedwe. Minda ya tiyi, minda, malo obiriwira obiriwira, ndi zina zambiri, zomwe zimafunikira chitetezo chachilengedwe, zimafunikira glufosinate-ammonium.
4. Kupalira kosiyanasiyana ndi kosiyana
Glyphosate imakhudzanso udzu wopitilira 160, kuphatikiza monocotyledonous ndi dicotyledonous, pachaka komanso osatha, zitsamba ndi zitsamba, koma sizoyenera kwa namsongole woyipa osatha.
Glufosinate-ammonium ndi mankhwala ophatikizika, opha anthu, opha, osatsalira omwe amagwiritsidwa ntchito mosiyanasiyana. Glufosinate itha kugwiritsidwa ntchito pa mbewu zonse (malinga ngati isanaponderezedwe pa mbewu, chivundikirocho chiyenera kuwonjezeredwa popopera mbewu mankhwalawa pakati pa mizere). kapena pansi). Pogwiritsa ntchito tsinde la udzu ndi njira yopopera masamba, imatha kugwiritsidwa ntchito pothana ndi udzu wa mitengo yazipatso yobzalidwa mochuluka, mbewu za mizere, masamba ndi malo osalimidwa; imatha kupha mwachangu mitundu yopitilira 100 ya udzu ndi udzu wotakata, makamaka Imakhala ndi zotsatira zabwino kwambiri pa udzu woyipa womwe umalimbana ndi glyphosate, monga udzu wa ng'ombe, purslane, ntchentche zazing'ono, ndipo wakhala adani. wa udzu ndi udzu wotakata.
5. Ntchito zosiyana zachitetezo
Glyphosate nthawi zambiri imafesedwa ndikuyikidwa patatha masiku 15-25 pambuyo pa mphamvu ya mankhwalawa, mwinamwake imakhala ndi phytotoxicity; glyphosate ndi biocidal herbicide. Kugwiritsa ntchito molakwika kudzabweretsa zoopsa zachitetezo ku mbewu, makamaka kugwiritsa ntchito kuwongolera udzu m'mitunda kapena m'minda ya zipatso Pamene , kuvulala kwamadzi kumatha kuchitika. Tiyenera kutsindika kuti glyphosate ingayambitse kusowa kwa kufufuza zinthu m'nthaka, kupanga kusowa kwa michere, ndikuwononga mizu. Kugwiritsa ntchito nthawi yayitali kumapangitsa kuti mitengo yazipatso ikhale yachikasu.
Glufosinate imatha kufesedwa ndikuziika m'masiku awiri mpaka 4. Glufosinate-ammonium ndi poizoni wochepa, wotetezeka, wachangu, wokonda zachilengedwe, kuvala pamwamba kumawonjezera kupanga, sikukhudza nthaka, mizu ya mbewu ndi mbewu zotsatila, ndipo kumakhala ndi zotsatira zokhalitsa. Drift ndiyoyenera kupalira mu chimanga, mpunga, soya, minda ya tiyi, minda ya zipatso, ndi zina zotero, zomwe sizingapewedwe panthawi yovuta kapena kudontha kwa madontho.
6. Tsogolo
Vuto lalikulu lomwe glyphosate likukumana nalo ndikukana mankhwala. Chifukwa cha ubwino wa glyphosate wapamwamba kwambiri, 5-10 yuan / mu (zotsika mtengo), komanso kagayidwe ka anthu mofulumira, glyphosate ili ndi njira yayitali kuti iwonongeke momasuka ndi msika. Poganizira vuto la kukana kwa glyphosate, kugwiritsidwa ntchito kosakanikirana komwe kulipo ndi njira yabwino yothanirana.
Chiyembekezo cha msika wa glufosinate-ammonium ndi wabwino ndipo kukula kwake ndikwachangu, koma zovuta zaukadaulo zakupanga kwazinthu ndizokwera, komanso njira yoyendetsera ndi yovuta. Pali makampani ochepa chabe apakhomo omwe angathe kupanga pamlingo waukulu. Katswiri wa udzu Liu Changling amakhulupirira kuti glufosinate singagonjetse glyphosate. Poganizira mtengo wake, 10 ~ 15 yuan / mu (mtengo wokwera), mtengo wa tani ya glyphosate ndi pafupifupi 20,000, ndipo mtengo wa tani ya glufosinate ndi pafupifupi 20,000 yuan. 150,000 - kukwezedwa kwa glufosinate-ammonium, kusiyana kwa mtengo ndi kusiyana kosawerengeka.
