Alkyl Polyglycosides-Mayankho Atsopano a Ntchito Zaulimi

Alkyl polyglycosides akhala akudziwika ndi kupezeka kwa opanga ulimi kwa zaka zambiri. Pali makhalidwe osachepera anayi a alkyl glycosides omwe akulimbikitsidwa kugwiritsa ntchito ulimi.

Choyamba, pali zonyowetsa zabwino kwambiri komanso zolowera. Kunyowetsa ndikofunika kwambiri kwa wopanga ulimi wouma ndipo kufalikira pamalo omera ndikofunikira kuti mankhwala ambiri ophera tizilombo ndi othandizira paulimi agwire ntchito.

Chachiwiri, palibe nonionic kupatula alkyl polyglycoside yomwe imawonetsa kulolerana kofanana ndi kuchuluka kwa ma electrolyte. Katunduyu amatsegula chitseko cha ntchito zomwe m'mbuyomu zinali zosafikirika kwa ma nonionics wamba komanso momwe ma alkyl polyglycosides amapereka zomwe zimafunidwa ndi ma nonionic surfactants pamaso pa mankhwala ophera tizilombo a ionic kwambiri kapena kuchuluka kwa feteleza wa nayitrogeni.

Chachitatu, ma alkyl polyglycosides okhala ndi utali wosiyanasiyana wa unyolo wa alkyl samawonetsa kusungunuka kwapang'onopang'ono ndi kutentha kowonjezereka kapena "mtambo wamtambo" wodziwika bwino wa alkylene oxide based nonionic surfactants. Izi zimachotsa chopinga chachikulu chopanga.

Pomaliza, mbiri ya ecotoxicity ya alkyl polyglycosides ndi ena mwa omwe amadziwika bwino ndi chilengedwe. Kuopsa kwa kugwiritsidwa ntchito kwawo pafupi ndi malo ovuta, monga madzi apamtunda, kumachepetsedwa kwambiri poyerekeza ndi alkylene oxide based nonionic surfactants.

Chimodzi mwazinthu zofunika kwambiri m'mbiri yaposachedwa ya mankhwala ophera udzu ndi kukhazikitsidwa kwa magulu angapo atsopano azinthu zomwe zimayikidwa pambuyo pake. Kubzala kumapezeka mbewu yomwe mukufuna ikamera ndipo ikayamba kukula. Njira imeneyi imathandiza mlimi kuti adziŵe ndi kulunjika za udzu wolakwawo m’malo motsatira njira imene yatsala pang’ono kugwa yomwe imafuna kuyembekezera zimene zingachitike. Mankhwala ophera udzu atsopanowa amasangalala ndi mitengo yotsika kwambiri chifukwa cha zochita zake zambiri. Kugwiritsiridwa ntchito kumeneku n'kopanda ndalama zowononga udzu komanso kumathandizira chilengedwe.

Zapezeka kuti ntchito zazinthu zambiri zomwe zagwiritsidwa ntchito pambuyo pake zimatha chifukwa chophatikizidwa mu tanki yosakaniza ya nonionic surfactant. Ma polyalkylene ethers amagwira bwino ntchito imeneyi. Komabe, kuwonjezera kwa feteleza wokhala ndi nayitrogeni kumapindulitsanso ndipo nthawi zambiri zolemba za herbicide zimalimbikitsa, makamaka, kugwiritsira ntchito zida zonse ziwiri pamodzi. Mumchere woterewu, nonionic wamba saloledwa bwino ndipo imatha "kutuluka" mumchere. Ubwino wopindulitsa ukhoza kutengedwa pakulekerera kwapamwamba kwa mchere wa AgroPG surfactants series. Mapiritsi a 30% ammonium sulphate amatha kuwonjezeredwa ku 20 % yothetsera alkyl polyglycosides ndikukhalabe ofanana.Magawo awiri pa 100 aliwonse otha kuthana ndi ammonium sulfate mpaka 40%. .

Kuphatikizika kwa zinthu zomwe zangokambidwa (kunyowa, kulolerana kwa mchere, adjuvant ndi kuyanjana) kumapereka mpata woganizira zophatikizira zowonjezera zomwe zimatha kupanga zida zingapo zogwirira ntchito. Alimi ndi ogwiritsira ntchito mwambo amafunikira kwambiri zothandizira zoterezi chifukwa zimathetsa vuto la kuyeza ndi kusakaniza mankhwala angapo. Zachidziwikire, katunduyo akaikidwa mu kuchuluka komwe adakonzeratu malinga ndi zomwe wopanga mankhwala ophera tizilombo, izi zimachepetsanso kuthekera kosakaniza zolakwika. Chitsanzo cha mankhwala ophatikizika otere ndi mafuta opopera a petroleum kuphatikiza methyl ester kapena mafuta a masamba ndi adjuvant ya nitrogen feteleza yankho logwirizana ndi alkyl polyglycosides. Kukonzekera kophatikizana koteroko ndi kukhazikika kokwanira kosungirako ndizovuta kwambiri. Zogulitsa zoterezi tsopano zikuyambitsidwa pamsika.

Ma Alkyl glycoside surfactants ali ndi ecotoxicity yabwino. Ndizofatsa kwambiri kwa zamoyo zam'madzi ndipo zimatha kuwonongeka kwathunthu. Makhalidwewa ndiye maziko oti ma surfactants awa adziwike kwambiri pansi pa malamulo a US Environmental Protection Agency. Mosasamala kanthu kuti cholinga chake ndi kupanga mankhwala ophera tizilombo kapena othandizira, amadziwika kuti alkyl glycosides amapereka ntchito zochepetsera zachilengedwe komanso kuthana ndi zoopsa ndi zosankha zawo, zomwe zimapangitsa kusankha kukhala kosavuta komanso kosavuta.

AgroPG alkyl polyglycoside ndi chinthu chatsopano, chochokera mwachilengedwe, chosawonongeka, komanso chokonda zachilengedwe chokhala ndi machitidwe angapo, omwe ndi oyenera kuganiziridwa ndi kugwiritsidwa ntchito popanga mankhwala ophera tizilombo ndi zinthu zina zaulimi. Pamene dziko likufuna kupititsa patsogolo ulimi ndikuchepetsa kuwononga chilengedwe, AgroPG alkyl polyglycosides athandizira izi.
