Alkyl Polyglycosides-New Solutions for Agricultural Applications

Alkyl polyglycosides yave ichizivikanwa uye inowanikwa kune vanogadzira zvekurima kwemakore mazhinji. Kune anokwana mana maitiro ealkyl glycosides anokurudzirwa kushandiswa kwekurima.

Chekutanga, pane yakanakisa yekunyorova uye inopinda mukati. Kunyorova kuita kwakakosha kune mugadziri wezvakaoma zvekurima maumbirwo uye kupararira pamusoro pechirimwa kwakakosha pakuita kwemishonga yakawanda yezvipembenene uye zvekurima zvekurima.

Chechipiri, hapana nonionic kunze kwealkyl polyglycoside inoratidza kushivirira kwakafanana kune yakakwira kuwanda kwe electrolytes. Ichi chivakwa chinovhura musuwo wezvikumbiro izvo zvaimbove zvisingasvikike kune zvakajairwa nonionics uye umo alkyl polyglycosides inopa inodiwa zvivakwa zvenonionic surfactants pamberi peionic yakanyanya kukuuraya zvipembenene kana kuwanda kwenitrogen fetereza.

Chechitatu, alkyl polyglycosides ine humwe huwandu hwehurefu hwealkyl cheni hairatidzi kunyungudika kwemukati nekuwedzera tembiricha kana "cloud point" chiitiko che alkylene oxide based nonionic surfactants. Izvi zvinobvisa chirevo chakakosha chekugadzirisa.

Chekupedzisira, iwo ecotoxicity profiles ealkyl polyglycosides ari pakati peakanyanya hushamwari kwezvakatipoteredza anozivikanwa. Ngozi mukushandiswa kwavo pedyo nenzvimbo dzakaoma, dzakadai semvura yepamusoro, inoderedzwa zvakanyanya maererano nealkylene oxide based nonionic surfactants.

Chimwe chebudiriro chakanyanya kukosha munhoroondo ichangoburwa yemishonga yesora kwave kuri kuunzwa kwemakirasi matsva akati wandei ezvigadzirwa zvinoiswa mushure mekushandisa. Post application inoitika mushure mekunge chirimwa chaunoda chamera uye chave padanho rekutanga kukura. Iyi nzira inobvumira murimi kunyatsoona uye kunanga mhando yesora inogumbura pachinzvimbo chekutevera nzira yepamberi iyo inoda kufanoona zvingaitika. Mishonga yesora mitsva iyi inonakidzwa nemitengo yakaderera nekuda kwekuita kwayo kwakanyanya. Kushandiswa uku kune hupfumi hwekudzivirira sora uye kunobatsira kune zvakatipoteredza.

Izvo zvakaonekwa kuti basa rezvizhinji zveiyi mushure-yakaiswa zvigadzirwa zvinogoneka nekuiswa mutangi musanganiswa weanonionic surfactant. Polyalkylene ethers inoshanda chinangwa ichi chaizvo. Zvisinei, kuwedzerwa kwenitrogen-ine fetiraiza kunobatsirawo uye kazhinji mazita emishonga yesora anokurudzira, zvechokwadi tsanangura, kushandiswa kwezvose zviri zviviri adjuvants. Mumishonga yakadai yemunyu, muyero we nonionic hautenderwi zvakanaka uye unogona "kubuda munyu" munyu. Mukana unobatsira unogona kutorwa weiyo yepamusoro munyu kushivirira kweiyo AgroPG surfactants series. Maconcentrations e30% ammonium sulfate anogona kuwedzerwa ku20 % solutions yealkyl polyglycosides iyi uye inoramba iri homogeneous.Two percent solutions inopindirana kusvika ku40% ammonium sulfate.Miedzo yemumunda yakaratidza alkyl polyglycosides kuti ipe inodiwa adjuvant madhara .

Iko kusanganiswa kwezvivakwa zvichangokurukurwa (kunyorova, kushivirira kwemunyu, adjuvant uye kuenderana) kunopa mukana wekufunga musanganiswa wezvinowedzera zvinogona kugadzira akawanda anoshanda adjuvants. Varimi nevashandisi vetsika vari kuda zvikuru maadjuvants akadai nekuti anobvisa kusagadzikana kwekuyera nekusanganisa ma adjuvants akati wandei. Ehe, kana chigadzirwa chaiswa muhuwandu hwakafanotemerwa maererano nekurudziro yezvinyorwa zvemugadziri wemishonga yezvipembenene, izvi zvakare zvinoderedza mukana wekusanganisa kukanganisa. Muenzaniso weiyo musanganiswa weadjuvant chigadzirwa mafuta epetroleum spray anosanganisira methyl ester kana mafuta emiriwo uye adjuvant yeyakaomeswa nitrogen fetiraiza mhinduro inoenderana nealkyl polyglycosides. Kugadzirira kwekusanganiswa kwakadaro nekugadzikana kwakakwana kwekuchengetedza idambudziko rinotyisa. Zvigadzirwa zvakadaro zvino zvave kuunzwa kumusika.

Alkyl glycoside surfactants vane yakanaka ecotoxicity. Izvo zvakapfava zvakanyanya kune zvipenyu zvemumvura uye zvinoodza zvachose. Aya maitiro ndiwo hwaro hwekuti masurfactants aya azivikanwe zvakanyanya pasi pemitemo yeUS Environmental Protection Agency. Pasinei nekuti chinangwa ndechekugadzira mishonga yekuuraya zvipembenene kana adjuvants, zvinozivikanwa kuti alkyl glycosides inopa mabasa ane hushoma hwezvakatipoteredza uye kubata njodzi nesarudzo dzavo, zvichiita kuti sarudzo iwedzere uye yakasununguka magadzirirwo.

AgroPG alkyl polyglycoside inyowani, yakasikwa, inogona kuparara, uye ine hushamwari hwezvakatipoteredza ine nhevedzano yemaitiro ekuita, iyo yakakodzera kutariswa uye kushandiswa mukugadzirwa kwepamusoro kwemishonga yezvipembenene uye zvigadzirwa zvekubatsira zvekurima. Sezvo nyika ichitsvaga kuwedzera kurima kwekurima uku ichideredza mhedzisiro yezvakatipoteredza, AgroPG alkyl polyglycosides ichabatsira kuve nechokwadi ichi.
