Hauv kev tsim cov qos yaj ywm, qos yaj ywm seedlings feem ntau yog siv rau kev txiav, thiab kev kho mob nrog cov nroj tsuag kev loj hlob regulators ua ntej txiav yuav txhawb rooting, shortening lub sij hawm qeeb yub, thiab txhim kho cov ciaj sia taus ntawm qos yaj ywm seedlings. Lub ntsiab cog kev loj hlob regulators uas txhawb rooting yog triacontanol thiab naphthalene acetic acid.
Triacontanol:Ua ntej txiav qos yaj ywm seedlings, soak lub hauv paus ntawm qos yaj ywm seedlings nrog 0.5 mg / L triacontanol li ib nrab ib teev, uas yuav txhawb rooting ntawm cuttings, shorten lub sij hawm qeeb yub thiab txhim kho cov ciaj sia taus.
Cov concentration yuav tsum tau tswj nruj me ntsis thaum lub sij hawm thov, thiab cov khoom siv chiv xws li potassium dihydrogen phosphate tuaj yeem ntxiv. Hauv kev tsim khoom thiab daim ntawv thov, siv {{0}}}.1 feem pua triacontanol soluble mis hmoov thiab dilute nws 2000 zaug nrog dej kom tau 0.5 mg/L triacontanol tov, tsau lub hauv paus ntawm qos yaj ywm seedlings li ib nrab ib teev. , uas yuav txhawb kev txiav rooting.
Naphthalene acetic acid:Ua ntej cov qos yaj ywm qos yaj ywm txiav, tsau ib kawg ntawm cov qos yaj ywm nrog 10 mg / L naphthalene acetic acid tov, uas tuaj yeem txhawb cov cag ntawm cuttings, ua kom lub sij hawm qeeb qeeb, thiab txhim kho cov ciaj sia taus. Naphthalene acetic acid yog cov dej-soluble heev, thiab 98 feem pua naphthalene acetic acid thawj cov tshuaj tuaj yeem raug xaiv rau kev kho cov qos yaj ywm. Thaum siv, dilute naphthalene acetic acid kom tau 10 mg / L naphthalene acetic acid tov, tsau cov qos yaj ywm nrog cov npaj naphthalene acetic acid tov thiab txiav ib kawg.
Ob leeg triacontanol thiab naphthalene acetic acid tuaj yeem txhawb kev cog qoob loo ntawm cov qos yaj ywm, ua kom lub sij hawm qeeb qeeb, thiab txhim kho kev ciaj sia ntawm cov qos yaj ywm. Yog li cov neeg cog qoob loo uas cog qos yaj ywm qab zib tuaj yeem xav muab nws sim!
Lus Ceeb Toom: Ua ntej siv, thov nco ntsoov sim ntawm thaj chaw me me. Vim muaj qhov sib txawv ntawm ib puag ncig, cov qoob loo yuav raug puas tsuaj, thov ua raws li cov lus qhia ntawm peb cov kws tshaj lij thiab siv lawv nruj me ntsis.
