Cov ntaub ntawv yooj yim
Lwm lub npe: 3-indolebutyric acid, indolylbutyric acid, IBA
Cov ntaub ntawv tseem ceeb: 1.05% aqueous tov, 2%, 50% soluble hmoov, 0.075% dej dispersible granules, 1%, 10% wettable hmoov.
Cov yam ntxwv ua
Indolebutyric acid yog cov nroj tsuag endogenous auxin regulator uas muaj peev xwm txhawb kev faib cell, elongation thiab nthuav, induce adventitious paus tsim, nce txiv hmab txiv ntoo nqi, tiv thaiv cov txiv hmab txiv ntoo poob, hloov tus piv ntawm txiv neej thiab poj niam paj, thiab lwm yam .;
Tom qab siv, nws tuaj yeem nqus tau los ntawm ntau cov ntaub so ntswg thiab cov kabmob ntawm cov nroj tsuag, tab sis nws tsis yooj yim rau kev coj noj coj ua hauv cov nroj tsuag lub cev. Nyob rau hauv ntau lawm, nws yog tsuas yog siv nyob rau hauv daim ntawv ntawm immersion los txhawb rooting ntawm cuttings los yog tswj kev noj haus kev loj hlob ntawm cov nroj tsuag;
Tsawg concentrations ntawm indolebutyric acid tuaj yeem ua ke nrog gibberellins thiab kinetin los txhawb kev loj hlob thiab kev loj hlob ntawm cov nroj tsuag, thaum cov concentrations siab induces zus tau tej cov ethylene endogenous thiab txhawb cov maturation thiab aging ntawm cov nroj tsuag cov ntaub so ntswg los yog kab mob.
Lub hom phiaj ntawm kev tswj
Rau cov txiv hmab txiv ntoo los yog parthenocarpy ntawm txiv lws suav, kua txob, eggplant, strawberry thiab lwm yam solanaceous qoob loo thiab txiv apples, citrus, pear, txiv duaj thiab lwm yam ntoo txiv hmab txiv ntoo.
Yuav siv li cas
(1) Rau cov txiv lws suav, kua txob, dib, eggplant, strawberry thiab lwm cov qoob loo solanaceous, siv 250mg / L tov los yog tshuaj tsuag cov paj thiab txiv hmab txiv ntoo los txhawb parthenocarpy thiab nce cov txiv hmab txiv ntoo qhov chaw.
(2) Thaum txiav tshuaj yej, mulberry, ntoo thuv, juniper thiab lwm yam nroj tsuag, siv 50 ~ 200mg / L tov los kho qia cuttings los txhawb rooting.
(3) Rau txiv apples, txiv duaj, kiwi thiab lwm yam txiv hmab txiv ntoo ntoo, siv 200 ~ 1000mg / L tov los kho, uas yuav txhawb rooting ntawm cuttings thiab txhim kho cov ciaj sia taus.
(4) Rau cov nplej, ginseng thiab qis qis, siv 10 ~ 80mg / L tov rau cov av, uas tuaj yeem txhawb nqa cov cag thaum ntxov thiab cov hauv paus hniav zoo tom qab hloov.
(5) Soaking grape ceg nyob rau hauv 5 ~ 20mg / L tov rau 24h yuav txhawb rooting thiab txhim kho cov ciaj sia taus ntawm cuttings.
Cov kev ceev faj
(1) Indolebutyric acid yog yooj yim decomposed los ntawm lub teeb thiab yuav tsum tau muab cia rau hauv ib tug txias thiab qhuav qhov chaw deb ntawm lub teeb. Nws yog qhov zoo tshaj plaws los npaj nws rau kev siv hauv kev tsim khoom thiab tsis txhob khaws cia rau lub sijhawm ntev.
(2) Yog hais tias indolebutyric acid yog tov nrog lwm cov nroj tsuag kev loj hlob regulators nrog rooting nyhuv, nws muaj peev xwm txhim khu lub rooting nyhuv, tab sis nws yog txwv tsis pub muab nws nrog muaj zog oxidants thiab alkaline tshuaj.
(3) Thaum kho cov nroj tsuag cuttings nyob rau hauv ntau lawm, yuav tsum tau saib xyuas kom tsis txhob muaj kev sib cuag ntawm nplooj ntawm cov tub ntxhais hluas nplooj thiab lub plawv nplooj ntawm cuttings nrog cov tshuaj, txwv tsis pub nws yog ib qho yooj yim ua rau cov tshuaj puas.
(4) Thaum siv indolebutyric acid, nruj me ntsis tswj cov concentration ntawm kev siv. Figs yog rhiab heev rau indolebutyric acid. 0.6mg/L indolebutyric acid kua tuaj yeem ua rau muaj kev puas tsuaj rau cov figs. Npaj thaum siv nws.
(5) Nyob rau tib lub sijhawm, txoj kev kho mob ntawm kev siv high-concentration indolebutyric acid rau ceev dipping yog qhov zoo tshaj li lub sij hawm ntev soaking nyob rau hauv tsawg-concentration tov.
