Naphthalene acetic acid yog abbreviated li NNA. Nws yog ib tug cog kev loj hlob regulator. Nws tau siv dav hauv kev tsim cov ntoo txiv ntoo hauv xyoo tas los no. Txawm li cas los xij, vim kev nkag siab tsis txaus ntawm cov tswj kev loj hlob, nws feem ntau ua rau muaj kev cuam tshuam tsis zoo rau cov txiv hmab txiv ntoo. Ob peb yam uas yuav tsum nco ntsoov:
1. Ua tib zoo mloog cov ntsiab lus sau npe, siv txoj hauv kev thiab lub sijhawm.
Tam sim no muaj cov npe ntawm naphthalene acetic acid: {{{0}}}.1 feem pua, 2.5 feem pua, 5 feem pua, 95 feem pua, 40 feem pua, 1 feem pua, 20 feem pua, 0.03 feem pua, thiab lwm yam., tsuas yog 20 feem pua. ntawm cov ntsiab lus tau sau npe rau ntawm cov txiv apples. Lub sij hawm ntawm kev siv, qhov ntau npaum li cas, thiab cov txheej txheem ntawm kev siv yuav tsum tau ua raws li nruj raws li cov lus qhia ntawm daim ntawv lo, thiab yuav tsum tsis txhob siv arbitrarily.
2. Thib ob, txoj kev siv cov ntoo txiv ntoo: (rau kev siv nkaus xwb)
(1) Txiv hmab txiv ntoo thinning:Jinguan thiab Marshal txiv apples thiab pears tau txau nrog 20 mg / L naphthalene acetic acid ob lub lis piam tom qab tawg tag, thiab Guoguang kua tau txau nrog 20 mg / L naphthalene acetic acid ntxiv rau 300 mg / L ethephon 10 hnub tom qab tawg tag, thiab cov txiv hmab txiv ntoo tseem ceeb. thinning teebmeem tau. .
(2) Tiv thaiv cov txiv hmab txiv ntoo ua ntej sau qoob loo:Tsugaru, Marshal thiab nws cov ceg luv luv, Hongyu thiab lwm cov txiv apples muaj cov txiv hmab txiv ntoo loj ua ntej sau qoob, 5-10 hnub ua ntej pib sau cov txiv hmab txiv ntoo ua ntej, tshuaj tsuag 30-40mg / L ntawm naphthalene acetic acid, Txau dua txhua 10 mus rau 15 hnub tuaj yeem tiv thaiv cov txiv hmab txiv ntoo poob ua ntej sau thiab txhawb cov txiv hmab txiv ntoo xim. Txau nrog 70 mg / L naphthalene acetic acid nyob ib ncig ntawm Lub Xya Hli 20 tuaj yeem txo cov txiv hmab txiv ntoo poob los ntawm 26 feem pua rau 46 feem pua, thiab nce tus nqi ntawm cov txiv hmab txiv ntoo xim los ntawm 49 feem pua.
(3)Txhawb nqa rooting ntawm cuttings:Kev kho cov txiv hmab txiv ntoo nrog {{0}} mg / L naphthalene acetic acid tov rau hauv paus dipping (ceev dipping) tuaj yeem txhim kho cov ciaj sia taus ntawm cuttings thiab nce tus nqi ntawm rooting. Noj 1000g ntawm talcum hmoov thiab ntxiv 0. Txoj kev no yog siv rau cuttings ntawm pomegranate thiab lwm yam seedlings. Nws tuaj yeem siv hauv paus ob peb, thiab cov ciaj sia taus yog ntau dua 90 feem pua.
(4)Inhibiting lub sprouting thiab tillering ntawm txiab:Ntau ntau yam ntawm Marshal thiab Fuji txiv apples yog nquag sprouting thiab sprouting ntawm cov txiab loj thiab saws, uas tsis tsuas yog noj ntau cov as-ham, tab sis kuj cuam tshuam rau lub qhov cua thiab lub teeb kis tau tus mob ntawm lub puab chamber. Yog tias 1 feem pua lossis 1.5 feem pua naphthalene acetic acid tov yog siv los npog cov txiav thiab pom kev txiav hauv lub caij ntuj no shearing, nws tuaj yeem tiv thaiv qhov tshwm sim ntawm sprouting.
(5)Txhawb kev rooting thiab ciaj sia ntawm cog seedlings:Thaum cog saplings, cov hauv paus hniav tuaj yeem muab tso rau hauv 50-100 mg / L naphthalene acetic acid tov rau 20 feeb los yog txau rau hauv cov hauv paus hniav txhawm rau txhim kho cov ciaj sia ntawm cov nroj tsuag. Ua ntej cog, soaking cov hauv paus hniav nrog tsawg concentration naphthalene acetic acid rau lub sij hawm ntev kuj tau txais txiaj ntsig zoo. Piv txwv li, 10 mg / L naphthalene acetic acid tov yog siv los ntub cov hauv paus hniav ntawm hawthorn rau 12 teev ua ntej cog. Piv nrog rau kev tswj hwm, qhov hnyav ntawm cov hauv paus hniav tshiab tau nce los ntawm 59.5 feem pua, cov hauv paus hniav tau nce los ntawm 63.6 feem pua, cov ciaj sia taus nce los ntawm 10-15 feem pua, thiab cov nplooj photosynthetic siv tau nce 29 feem pua. ~ 83 feem pua , thiab kev loj hlob ntawm cov tua tshiab tau nce los ntawm 20cm ~ 34cm.
(6)Tiv thaiv grapes shattering:Thaum Jufeng txiv hmab txiv ntoo yog qhov loj ntawm cov txiv laum huab xeeb, dipping pob ntseg nrog 300mg / L naphthalene acetic acid tuaj yeem tiv thaiv cov nplej tawg.
(7)Txhawb cov noob germination:Hawthorn noob shells yog tuab thiab tawv, thiab germination yog nyuaj. Nrog rau txoj kev stratification, nws yuav siv sij hawm ob lub caij ntuj no kom germinate. Noob soaking nrog 50-100 mg/L naphthalene acetic acid tov tuaj yeem txhawb cov germination ntawm hawthorn noob.
(8)Txhawb nqa parthenocarpy:Kev kho strawberry nrog 0.25mg/L naphthalene acetate lanolin ointment thaum lub sij hawm flowering lub sij hawm ntawm strawberry yuav induce parthenocarpy ntawm strawberry.
(9)Txhawb kev kho ntawm qhov txhab:Ntxiv 50 mg / L naphthalene acetic acid nyob rau hauv 40 feem pua fumei arsenic 50 lub sij hawm cov tshuaj tuaj yeem txhim kho qhov kev kho ceev ntawm rot scars, txo qhov rov tshwm sim ntawm cov kab mob rot, thiab ntxiv dag zog rau kev tswj cov nyhuv.
(10)Txhawm rau txhim kho qhov kho ntawm qhov sib koom ua ke:ua ib qho kev daws nrog 1g ntawm naphthalene acetic acid thiab 10g dej, ces txiav mus rau hauv ib daim hlab nrog cov ntawv pov tseg thiab raus rau hauv cov tshuaj, tshem tawm thiab qhuav nyob rau hauv ntxoov ntxoo los tsim cov tshuaj hormones. Wrapping lub grafted qhov chaw ntawm txiv hmab txiv ntoo ntoo nrog cov tshuaj hormones yog conducive rau tsim ntawm callus. Piv nrog rau qhov tsis muaj kev sib tw, nws tuaj yeem muaj sia nyob 3 mus rau 5 hnub ua ntej, thiab qhov ciaj sia taus yog 99 feem pua.
Lus Ceeb Toom: Ua ntej siv, thov nco ntsoov sim ntawm thaj chaw me me. Vim muaj ntau yam xws li ib puag ncig, nws yuav ua rau cov qoob loo puas tsuaj. Thov ua raws li cov lus qhia tshaj lij thiab siv nws nruj me ntsis.
