Imichiza yezoLimo iAuxin Hormones Sodium Naphthoacetate Acid Naa-Na 98%Tc
Iimpawu zomzimba kunye neekhemikhali
Le mveliso i-granule emhlophe, ipowder okanye i-crystalline powder;Ayinavumba okanye inevumba elincinane, imnandi kancinci kwaye inetyuwa.Le mveliso inyibilika ngokulula emanzini kwaye inyibilika kancinane kwi-ethanol.
Izinzile emoyeni.Isisombululo sizinzile kwi-pH ye-7-10.Inyibilika kakhulu emanzini (53.0g/100ml, 25℃).Inyibilika kwi-ethanol (1.4g/100ml).Ixabiso le-pH yesisombululo samanzi ngu-8. Ikhono lokuthintela ukuvutshelwa kunye namandla e-bactericidal buthathaka kune-benzoic acid.Kwi-pH 3.5, isisombululo se-0.05% sithintela ngokupheleleyo ukukhula kwemvubelo, kwaye kwi-pH 6.5, i-concentration ye-2.5% isisombululo iyadingeka.
Izinto eziluncedo nezingeloncedo
(1) Ukunyibilika okugqwesileyo: ukucoceka okuphezulu kwe-alpha-naphthalene acetate sodium inamanzi kunye neoyile ukunyibilika kabini, ngoko inokuzimela ngokuzimeleyo ibe ngamanzi, umgubo, ukhilimu, igranule kunye nezinye iifom zedosi, ekulula kakhulu ukuyisebenzisa kwaye inomthamo omkhulu. isiphumo esihle.Ngenxa yokuba i-molecule enye kwisisombululo, ihlakazekile ngokulinganayo, kulula ukuxutywa zizityalo, kunye nomxholo oqhelekileyo we-80% we-α-naphthalene acetate sodium kufuneka ichithwe kunye ne-ethanol, ukusetyenziswa kuphazamiseka kakhulu.Ikhona kwimeko yamaqela eemolekyuli kwi-powder cream, ukusasazeka kubi, kwaye umphumo awukho ngokwemvelo.
(2) Ukucoceka okuphezulu, akukho kungcola, iziphumo ezinobungozi obungenabuthi: ukucoceka okuphezulu kwe-α-naphthalene i-acetate ye-sodium ecocekileyo ngaphezu kwe-98%, iqulethe inani elincinci lamanzi, ayinayo enye into engcolileyo, ngoko ekusebenziseni kwayo ngokufanelekileyo i-concentration. uluhlu ngokubanzi aluyi kubangela umonakalo weziyobisi kwizityalo, kunye ne-α-naphthalene acetate yesodium eqhelekileyo ngenxa yokuqulatha i-20% yokungcola kwezinto eziphilayo, Kuluhlu lokugxininiswa kokusetyenziswa okusebenzayo, kuya kubangela ingozi yeziyobisi kumagqabi amancinci, amaqabunga kunye nezithole zezityalo.Ukukhanya kubangela amabala amnyama, ubunzima bubangela ukufa, kwaye kukho ukungcola okuphilayo okudala ingozi kumzimba womntu kunye nokusingqongileyo.Naluphi na uhlobo lokulawula ukukhula kwezityalo kunye ne-pesticide, ukucoceka kwayo kuhambelana nomphumo wayo, njenge-sodium ephezulu ecocekileyo i-α-naphthalene acetate 5ppm (5μg / g) enefuthe elihle, ngelixa i-sodium α-naphthalene acetate idinga ukufikelela kwi-20ppm. (20μg/g) ukuba nefuthe.
(3) Ukungahambi kakuhle: ukucoceka okuphezulu kwe-α-naphthalene acetate sodium ingasetyenziselwa ukudibanisa kunye nabalawuli abaninzi bokukhula kwezityalo, ezifana ne-auxin, i-nitrophenolate ye-sodium, i-rooting substances, i-fungicides, izichumisi, njl.;I-sodium ye-alpha-naphthalene acetate eqhelekileyo ayisetyenziswanga ngokubanzi.
Iimpawu zokusebenza
Ukucoceka okuphezulu kwe-α-naphthalene acetate sodium yi-hormone yokukhulaumlawuli wokukhula kwezityalongeziphumo ezintathu ezinkulu.Eyokuqala kukukhuthaza ukubunjwa kweengcambu ze-advental kunye nokubunjwa kweengcambu, ngoko ingasetyenziselwa ukukhuthaza iingcambu zembewu kunye ne-rooting, kodwa ukugxininiswa kakhulu kunokuthintela i-rooting.Okwesibini kukukhuthaza ukwanda kweziqhamo kunye neengcambu ze-tuber, ngoko inokusetyenziswa njengento yokwandisa, kwaye iimvavanyo zentsimi ziye zabonisa ukuba kunokunyusa kakhulu isivuno kunye nokuphucula umgangatho weepesika zenkawu, iidiliya, ivatala, iikomkomere, iitumata. , iipepile, isitshalo seqanda, amapere, iiapile.Ngelo xesha, ikhuthaza ukwanda ngokukhawuleza kweeseli, kwaye izinga lokukhula kwe-solanum ephathwayo livelisa utshintsho olumangalisayo.Impembelelo ye-mushroom ibaluleke kakhulu kwaye ayinciphisi umgangatho wesiqhamo.Okwesithathu kukuthintela ukuwa kweentyatyambo kunye neziqhamo, kunye nomsebenzi wokuchasana nokuwa.Ukongeza, ikwanayo nemisebenzi ye-auxin ngokubanzi, njengokukhuthaza ukukhula, ukukhuthaza ukuhlanganiswa kwe-chlorophyll, kunye nokukhuthaza ukuhlukana kweentyatyambo kunye neentyatyambo.Ngoko ke, inefuthe lokukhuthaza intyatyambo kunye neziqhamo, ukukhuthaza amasebe anqabileyo kunye namagqabi, ukwandisa isivuno kunye nokuphucula umgangatho, kunye nokuphucula ukuxhathisa kwezityalo kwimbalela, ukubanda kunye nokulala.
Indlela yokusetyenziswa
Indlela yokusetyenziswa kokucoceka okuphezulu kwe-α-naphthalene acetate sodium
(1) Sebenzisa yedwa
Ukucoceka okuphezulu kwe-sodium α-naphthalene acetate inokulungiswa ngokwahlukileyo emanzini, ukhilimu, umgubo kunye nezinye iifom zedosi yokukhuthaza ukukhula, ukuhluma, ukugcinwa kweentyatyambo, ukugcinwa kweziqhamo kunye nokunye.Umthamo wokusetyenziswa okukodwa: 2 grams ukuya kwi-30 kilograms zamanzi.Isikhumbuzo esikhethekileyo: ubuninzi buxhomekeke kumonakalo weziyobisi.
(2) Isetyenziswe ngokudibanisa ne-sodium nitrophenolate
Ukucoceka okuphezulu kwe-α-naphthalene acetate sodium inokudibaniswa ne-nitrophenolate ye-sodium, i-hormone yokukhula, i-fungicide, isichumisi, njl njl. I-sodium ecocekileyo ye-alpha-naphthalene acetate inokudibaniswa ne-sodium nitrophenolate eJapan, iTaiwan ineminyaka engaphezu kwe-20 yembali, ezi zimbini Amacandelo anokusebenzisana ngokubambisana, ukwandisa ukusebenza kwe-spectrum yeziyobisi, ukusetyenziswa kokunciphisa uxinzelelo, zombini zinefuthe le-sodium nitrophenolate, kodwa zinefuthe le-sodium α-naphthalene acetate, ukufezekisa umphumo ophindwe kabini ngesiqingatha somzamo.
Isicelo
Indlela yokusebenza
Ukucoceka okuphezulu kwe-sodium naphthalene acetate yi-auxin plant regulator, engena emzimbeni wesityalo ngamagqabi, isikhumba esithambileyo kunye nembewu yezityalo, kwaye ihanjiswe kwiindawo zokukhula okunamandla (amanqaku okukhula, amalungu amancinci, iintyatyambo okanye iziqhamo) kunye nesondlo. ukuhamba.I-sodium naphthalene acetate ngokucacileyo yakhuthaza ukuphuhliswa kweengcambu zengcambu (ingcambu ye-powder).Ingakhupha iintyatyambo, ithintele ukuwa kweziqhamo, yenze isiqhamo esingenambewu, ikhuthaze ukuvuthwa kwangethuba kwaye yandise isivuno.Ngeli xesha, i-sodium naphthalene acetate inokuphucula amandla okumelana nembalela, ukumelana nokubanda, ukumelana nezifo, ukuxhathisa kwe-saline-alkali kunye nokunganyangeki komoya oshushu kwezityalo.Ukucoceka okuphezulu kwe-sodium naphthalene acetate yavavanywa eJapan, eTaiwan nakwezinye iindawo, kwaye umphumo wokusetyenziswa kwayo wawungcono kakhulu kune-sodium naphthalene acetate eqhelekileyo.
Indlela yokuchonga
