I-Tripyrasulfone, ifomula yesakhiwo iboniswa kuMfanekiso 1, Isimemezelo Sokugunyazwa Kwelungelo Lobunikazi base-China emasimini ukulawula ukhula lwegramineous.
Indlela yokwenza:
I-Triazole sulfotrione iwuhlobo olusha lwesibulala-magciwane oluvimbela i-p-hydroxyphenylpyruvate dioxygenase (HPPD), eguqula i-p-hydroxyphenylpyruvate ibe umchamo ngokuvimbela umsebenzi we-HPPD ezitshalweni. Inqubo ye-asidi emnyama ivinjiwe, okuholela ekuhlanganiseni okungavamile kwe-plastoquinone, futhi i-plastoquinone iyi-cofactor eyinhloko ye-phytoene desaturase (PDS), futhi ukuncishiswa kwe-plastoquinone kuvimbela isenzo se-catalytic se-PDS, okubuye kuthinte i-biosynthesis ye-carotenoids. emzimbeni okuhlosiwe, okuholela ekubeni yi-albinism yamaqabunga nokufa.
Izici zomsebenzi:
1. I-Tripyrasulfone iyisivimbeli esisha se-HPPD, okungokokuqala ngqa ukuthi i-HPPD inhibitor isetshenziswe ngokuphepha ekwelashweni kwesiqu esingemuva kwesithombo kanye nesifutho seqabunga ensimini yerayisi.
2. I-Tripyrasulfone ingaxazulula ngempumelelo inkinga yembewu engazweli kanye ne-barnyardgrass engazweli kanye ne-barnyardgrass.
3. Akukho ukumelana nokusebenzelana phakathi kwe-Tripyrasulfone nomuthi ovamile wamanje, ongaxazulula ngempumelelo izinkinga zamanje nezesikhathi esizayo eziyinkimbinkimbi zokumelana ne-millet notshani be-barnyard.
4. I-Tripyrasulfone ingaxutshwa nenani elifanele le-2 methyl · methazopine ukuze kuthuthukiswe ukulawulwa kahle kotshani obunamaqabunga abanzi kanye nokhula lwenhlaka futhi kuthuthukiswe ukusebenza kahle kokukhula.
Izinto ezidinga ukunakwa:
1. Ngaphambi kokufaka isicelo, kuyadingeka ukwenza ukwelashwa okuvaliwe ukunciphisa isisekelo sokhula kanye neminyaka yamaqabunga.
2. I-Tripyrasulfone ayikwazi ukuxutshwa nanoma iyiphi i-organophosphorus, i-carbamate, i-paclobutrazol insecticide kanye nama-fungicides noma isetshenziswe phakathi kwezinsuku ezingu-7. Ingasetshenziswa ngesikhathi esisodwa phakathi nesikhathi sonke sokukhula kwerayisi.
3. Akuvunyelwe ukusabalalisa umanyolo izinsuku ezingu-7 ngaphambi nangemva kokufaka isicelo.
Akuvunyelwe ukuxuba ukusetshenziswa kwe-bensulfuron-methyl, i-pentaflusulfurochlor namanye ama-ALS inhibitors kanye ne-quinclorac.
4. Isimo sezulu libalele, futhi izinga lokushisa elingcono kakhulu lokufafaza ngu-25~35 ℃. Uma izinga lokushisa lingaphezu kuka-38 ℃, ukufafaza akunconywa. Uma kuba nemvula emahoreni angu-8 ngemva kokufafaza, isifutho esingeziwe siyadingeka.
5. Khipha amanzi ngaphambi kokufafaza ukuze uqinisekise ukuthi ngaphezu kwe-2/3 yamaqabunga okhula atholakala emanzini futhi uwugcobe ngokugcwele isibulala-zinambuzane; Ngemuva kokufakwa kwesibulala-zinambuzane, amanzi abuyiselwa ku-5 ~ 7 cm phakathi namahora angu-24-48 futhi agcinwe izinsuku ezingaphezu kwezingu-7. Uma isikhathi sokugcinwa kwamanzi siba side, umphumela wokulawula uzinzile.
6. Ezinye izinhlobo zerayisi ze-indica ziyazwela ku-Tripyrasulfone, okungase kuholele ekubeni yi-albinism yamaqabunga, kodwa ingatholakala, ngaphandle kokuphazamisa isivuno serayisi.
Isifinyezo:
I-Tripyrasulfone inoxhaxha olubanzi lwemithi yokubulala ukhula kanye nomsebenzi wokusika okuphezulu kwangemva kwezithombo, ikakhulukazi i-Echinochloa crus-galli, i-Leptochloa chinensis, i-Monochoria vaginalis ne-Eclipta prostrata, futhi ayimelani nemithi yokubulala ukhula evamile njengamanje emasimini elayisi, njenge-cyhalochlor, I-pentafluorosulphonachlor ne-dichloroquinoline acid. Ngasikhathi sinye, iphephile ezithonjeni zelayisi futhi ilungele ukutshalwa kabusha kwerayisi kanye nezinsimu zokutshala imbewu ngqo, Kuyi-ejenti esebenzayo yokuxazulula inkinga yokukhula kwamakhemikhali ensimini ye-paddy njengamanje - ukulawula utshani be-barnyard obungazweli kanye namabele, futhi amathemba esicelo abanzi. Ngokuhlolwa okuningi, kwatholakala ukuthi izinhlanganisela eziningi ezichazwe ku-Tripyrasulfone zinokukhetha okuhle kotshani botshani njenge-Zoysia japonica, i-bermudagrass, i-fescue ende, i-bluegrass, i-ryegrass, i-seashore paspalum, futhi ingalawula ukhula oluningi oluyisihluthulelo nokhula olunamaqabunga abanzi. . Ukuhlolwa kukabhontshisi wesoya, ukotini, ubhekilanga, amazambane, isihlahla sezithelo nemifino ngaphansi kwezindlela ezihlukene zokufaka isicelo nakho kubonise ukukhetha okuhle kakhulu kanye nenani lezentengiselwano.
Isikhathi sokuthumela: Feb-14-2023
