Iikhemikhali zezolimo iiHormones ze-Auxin iSodium Naphthoacetate Acid iNaa-Na 98% Tc
Iimpawu zomzimba nezekhemikhali
Le mveliso yi-granule emhlophe, umgubo okanye i-crystalline powder; Ayinavumba okanye inevumba elincinci, imnandi kwaye inetyuwa. Le mveliso inyibilika lula emanzini kwaye inyibilika kancinci 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 yi-8. Amandla okuthintela ukubila kunye namandla okubulala iintsholongwane abuthathaka kune-benzoic acid. Kwi-pH ye-3.5, isisombululo se-0.05% sithintela ngokupheleleyo ukukhula kwemvubelo, kwaye kwi-pH ye-6.5, kufuneka uxinzelelo lwesisombululo esingaphezulu kwe-2.5%.
Iingenelo kunye nokungalungi
(1) Ukunyibilika okugqwesileyo: ubunyulu obuphezulu α-naphthalene acetate sodium ine-sodium yamanzi kunye neoyile enokunyibilika kabini, ngoko ke ingenziwa ngokuzimeleyo ibe ngamanzi, umgubo, ukhilimu, igranule kunye nezinye iindlela zomthamo, okulula kakhulu ukuyisebenzisa kwaye inesiphumo esihle kakhulu. Ngenxa yokuba yimolekyuli enye kwisisombululo, isasazwa ngokulinganayo, kulula ukuyifunxa zizityalo, kwaye umxholo oqhelekileyo we-80% α-naphthalene acetate sodium kufuneka ichithwe nge-ethanol, ukusetyenziswa kwayo akunangxaki. Ikhona kwimeko yamaqela eemolekyuli kwi-cream powder, ukusasazeka kwayo kuncinci, kwaye isiphumo asilungile ngokwendalo.
(2) Ubunyulu obuphezulu, akukho kungcola, iziphumo ebezingalindelekanga ezingenabungozi: ubunyulu obuphezulu be-α-naphthalene acetate sodium ubunyulu obungaphezulu kwe-98%, buqulathe amanzi amancinci, abunazo ezinye izinto ezingcolileyo eziphilayo, ngoko ke ekusebenziseni kwayo kakuhle uluhlu loxinzelelo ngokubanzi akuyi kubangela umonakalo kwizityalo ngamayeza, kwaye i-α-naphthalene acetate sodium eqhelekileyo ngenxa yokuba iqulethe i-20% yokungcola kwendalo, Kuluhlu loxinzelelo olusebenzayo lokusetyenziswa, luya kubangela umonakalo kwiziyobisi kumagqabi amatsha, amahlumela kunye nezithole zezityalo. Ukukhanya kubangela amabala amnyama, ubunzima bubangela ukufa, kwaye kukho ezinye izinto ezingcolileyo eziphilayo ezibangela umonakalo emzimbeni womntu nakwindalo esingqongileyo. Naluphi na uhlobo lolawulo lokukhula kwezityalo kunye ne-pesticide, ubunyulu bayo bunxulumene nesiphumo sayo, njenge-high-purity sodium α-naphthalene acetate 5ppm(5μg/g) enesiphumo esihle, ngelixa i-sodium α-naphthalene acetate eqhelekileyo kufuneka ifikelele kwi-20ppm(20μg/g) ukuze ibe nesiphumo.
(3) Ukuxubana okulungileyo: ubunyulu obuphezulu be-α-naphthalene acetate sodium bungasetyenziswa kunye nabalawuli abaninzi bokukhula kwezityalo, njenge: auxin, sodium nitrophenolate, izinto ezisusa iingcambu, iifungicides, izichumisi, njl.njl.; I-acetate eqhelekileyo ye-sodium alpha-naphthalene ayisetyenziswa ngokudibeneyo.
Iimpawu zokusebenza
I-α-naphthalene acetate sodium ecocekileyo kakhulu yi-hormone yokukhulaumlawuli wokukhula kwezityaloeneziphumo ezintathu eziphambili. Eyokuqala kukukhuthaza ukwakheka kweengcambu ezisandul’ ukuzalwa kunye nokwakheka kweengcambu, ukuze isetyenziselwe ukukhuthaza iingcambu zembewu kunye nokuhluma kweengcambu, kodwa ukugxila kakhulu kunokuthintela ukuhluma kweengcambu. Eyesibini kukukhuthaza ukwanda kweziqhamo kunye neengcambu zeengcambu, ukuze isetyenziswe njengento yokwandisa, kwaye uvavanyo lwasentsimini lubonakalise ukuba lunokunyusa kakhulu isivuno kwaye luphucule umgangatho weepesika zeenkawu, iidiliya, iwatermelon, iikomkomere, iitumato, iipepile, i-eggplant, iipere, ii-apile. Kwangaxeshanye, ikhuthaza ukwanda ngokukhawuleza kweeseli, kwaye izinga lokukhula kwe-solanum enyangiweyo livelisa utshintsho olumangalisayo. Isiphumo sekhowa sibaluleke kakhulu kwaye asinciphisi umgangatho wesiqhamo. Eyesithathu kukuthintela ukuwa kweentyatyambo kunye neziqhamo, ngomsebenzi wokulwa nokuwa. Ukongeza, ikwanemisebenzi ye-auxin ngokubanzi, njengokukhuthaza ukukhula, ukukhuthaza ukwenziwa kwe-chlorophyll, kunye nokukhuthaza ukwahluka kwamahlumela kunye neentyatyambo. Ke ngoko, inefuthe lokukhuthaza ukudubula kunye neziqhamo, ukukhuthaza amasebe namagqabi atyebileyo, ukwandisa isivuno kunye nokuphucula umgangatho, kunye nokuphucula ukumelana kwezityalo kwimbalela, kubanda kunye nokuhlaliswa.
Indlela yokusebenzisa
Indlela yokusebenzisa i-α-naphthalene acetate sodium ecocekileyo kakhulu
(1) Sebenzisa yodwa
I-sodium α-naphthalene acetate ecocekileyo kakhulu ingalungiswa ngokwahlukeneyo ibe ngamanzi, ukhilimu, umgubo kunye nezinye iindlela zokulinganisa ukukhuthaza ukukhula, ukuhluma iingcambu, ukugcinwa kweentyatyambo, ukugcinwa kweziqhamo njalo njalo. Umlinganiselo wokusetyenziswa kube kanye: iigram ezi-2 ukuya kwiikhilogram ezingama-30 zamanzi. Isikhumbuzo esikhethekileyo: ubungakanani obukhulu bunokonakala ngamayeza.
(2) Isetyenziswa kunye ne-sodium nitrophenolate
I-α-naphthalene acetate sodium ecocekileyo kakhulu inokudityaniswa ne-sodium nitrophenolate, i-growth hormone, i-fungicide, isichumisi, njl. I-α-naphthalene acetate ecocekileyo kakhulu inokudityaniswa ne-sodium nitrophenolate eJapan, iTaiwan ineminyaka engaphezu kwama-20 yembali, ezi zinto zimbini zinokusebenzisana ngaxeshanye, zandise ukusebenza kakuhle kwe-spectrum yamayeza, zisebenzise ukunciphisa uxinzelelo, zombini zinefuthe le-sodium nitrophenolate, kodwa zikwanalo nefuthe le-sodium α-naphthalene acetate, ukufezekisa iziphumo eziphindwe kabini ngesiqingatha somzamo.
Isicelo
Indlela yokusebenza
I-sodium naphthalene acetate ecocekileyo kakhulu yi-auxin plant regulator, engena emzimbeni wesityalo ngamagqabi, ulusu oluthambileyo kunye nembewu yezityalo, kwaye ithuthwa iye kwiindawo zokukhula okunamandla (amanqaku okukhula, amalungu amancinci, iintyatyambo okanye iziqhamo) ngokuhamba kwezondlo. I-sodium naphthalene acetate ngokucacileyo yakhuthaza uphuhliso lwencam yengcambu (umgubo weengcambu). Inokubangela ukudubula, ithintele ukuwa kweziqhamo, yenze iziqhamo ezingenambewu, ikhuthaze ukuvuthwa kwangethuba kwaye inyuse isivuno. Okwangoku, i-sodium naphthalene acetate inokuphucula amandla okumelana nembalela, ukumelana nokubanda, ukumelana nezifo, ukumelana ne-saline-alkali kunye nokumelana nomoya oshushu owomileyo wezityalo. I-sodium naphthalene acetate ecocekileyo kakhulu yavavanywa eJapan, eTaiwan nakwezinye iindawo, kwaye isiphumo sayo sokusebenzisa sasingcono kakhulu kuneso se-sodium naphthalene acetate eqhelekileyo.
