Kev Siv Cov Kev Cai Loj Hlob Ntawm Cov Zaub: Legumes
1. Ntsuab taum (Snap Beans)
Germination Promotion
Txhawm rau kom ceev cov noob germination ceev thiab nce qhov germination tus nqi - yog li ua kom cov nroj tsuag zoo ib yam thiab ruaj khov - cov noob feem ntau tuaj yeem tsau rau 6 teev hauv ib qho kev daws teeb meem hauv qab no: Gibberellic Acid ntawm 200–300 mg / L, Sodium Nitrophenolates ntawm 6–8 mg/Leth-1-6-Diethyl 2 amino acids ntawm 6–8 mg/Leth-10–1DA amino acid. mg/L. Tag nrho peb txoj kev ua tau zoo ua tiav qhov txiaj ntsig no.
Kev Tswj Xyuas Thaum Ntxov thiab Kev Loj Hlob
Cov taum ntsuab feem ntau tsis tas yuav tsum tau cog qoob loo hauv tsev zov me nyuam; xwb, lawv feem ntau ncaj-sown nyob rau hauv qhib teb. Tsis tas li ntawd, cov txheej txheem rau kev siv cov kev tswj hwm kev loj hlob ntawm cov nroj tsuag-los ntawm lub sijhawm tshwm sim los ntawm kev loj hlob ntawm nruab nrab mus rau lig-yog qhov zoo sib xws, raws li tau teev tseg hauv qab no:
Sodium Nitrophenolates
Siv Sodium Nitrophenolates ntawm qhov concentration ntawm 6 mg/L, txau cov nroj tsuag kwv yees li 10 hnub, pib ntawm qhov tseeb-nplooj theem. Qhov kev kho no tuaj yeem ua ntej lub sijhawm taum ntsuab sau los ntawm 8-10 hnub thiab nce tawm los ntawm kwv yees li 30%.
Diethyl aminoethyl hexanoate (DA-6)
Siv DA-6 ntawm qhov concentration ntawm 5-15 mg/L, txau cov nroj tsuag kwv yees li 10 hnub, pib ntawm qhov tseeb-nplooj theem. Qhov kev kho no tuaj yeem ua rau lub sijhawm taum ntsuab sau los ntawm 3-5 hnub thaum ib txhij ncua kev loj hlob thiab ncua sij hawm tag nrho cov qoob loo, ua rau cov qoob loo nce ntawm 55% -60%.
Triacontanol
Siv Triacontanol ntawm qhov concentration ntawm 0.5 mg / / L los ntawm kev txau cov nroj tsuag thaum pib paj. Qhov no txhawb nqa pod qhov chaw. Ib daim ntawv thov thib ob yuav tsum tau ua 7-10 hnub tom qab; nyob rau hauv tag nrho, 2-3 daim ntawv thov raug pom zoo. Cov txheej txheem no tuaj yeem nce taum ntsuab tawm los ntawm kwv yees li 10%, nrog rau kev cuam tshuam tshwj xeeb rau kev tsim khoom thaum ntxov.
Cov Lus Qhia Siv Tseem Ceeb: Lub sijhawm zoo rau daim ntawv thov ntawm taum ntsuab yog thaum pib ntawm paj, vim qhov no yog qhov zoo tshaj plaws rau paj tuav thiab nce pod tsim. Yog tias siv los yog ntxov dhau los lossis lig dhau lawm, cov txiaj ntsig yuav tsis raug hais raws li cov uas tau ua tiav thaum lub sijhawm paj. Triacontanol yog sib xws nrog tshuaj tua kab thiab kab kawm; tshwj xeeb, nws cov kev ua tau zoo ntxiv ntxiv thaum sib xyaw thiab siv ua ke nrog Monopotassium Phosphate (KH₂PO₄).
2. Cowpea (Vigna unguiculata)
Txhawb nqa noob germination
Brassinolide (BR)
Soak cov noob hauv 0.01-0.05 mg/L Brassinolide tov rau 10 teev tuaj yeem ua kom cov pa oxygen hauv cov noob thiab txhawb kev loj hlob.
Humic Acid
Soak cov noob hauv 10-50 mg/L Humic Acid tov rau 12 teev tuaj yeem txhawb kev loj hlob.
Sodium Nitrophenolates
Soaking noob hauv 3-6 mg/L Sodium Nitrophenolates tov rau 12 teev tuaj yeem txhawb kev loj hlob.
DA-6
Soak cov noob hauv 10-15 mg/L DA-6 tov rau 12 teev tuaj yeem txhawb kev loj hlob.
Nce yields
Triacontanol
Kev kho cowpea cov nroj tsuag nrog Triacontanol tuaj yeem ua rau cov pod-teeb tus nqi. Qhov no yog qhov tshwj xeeb tshaj yog thaum lub caij nplooj ntoos hlav, thaum qhov kub qis feem ntau cuam tshuam kev tsim cov pods; Nyob rau hauv cov xwm txheej zoo li no, Triacontanol kev kho mob tuaj yeem ua rau muaj txiaj ntsig zoo rau lub pod-teeb tsa tus nqi, ua kom muaj txiaj ntsig zoo thaum ntxov thiab nce nyiaj txiag rov qab los. Los ntawm foliar txau ib 0.5 mg/L Triacontanol tov ib zaug nyob rau hauv thawj flowering theem thiab dua nyob rau hauv thaum ntxov pod-set theem, cowpea yields yuav nce 12%. Daim ntawv thov yuav tsum tau txau tag nrho cov nroj tsuag nrog 0.5 mg/L Triacontanol thaum lub sij hawm pib flowering thiab thaum ntxov pod-teeb theem.
DA-6
DA-6 txhim kho photosynthesis, nce chlorophyll cov ntsiab lus, boosts cov nroj tsuag uptake ntawm CO₂, tswj cov nroj tsuag cov pa roj carbon-to-nitrogen (C/N) piv, thiab txhim kho cov kab mob tsis kam ntawm ob nplooj thiab tag nrho cov nroj tsuag, ua rau muaj zog loj hlob. Thaum lub caij cog qoob loo, siv cov tshuaj tsuag foliar ntawm 10-12 mg/L DA-6 ntawm 15-hnub ib ntus-rau tag nrho ntawm 2 mus rau 3 daim ntawv thov- tuaj yeem nce yields ntau dua 20%.
Kev khaws cia tom qab sau qoob loo
2,4-D:Kev kho cov qoob loo cog qoob loo nrog 10-20 mg/L daws ntawm 2,4-D nce qib ntawm cov tshuaj endogenous IAA nyob rau hauv cov pods thaum tib lub sij hawm txo cov kev ua ntawm peroxidase. Tsis tas li ntawd, qhov kev kho mob no ib nrab inhibits kev thauj cov khoom noj los ntawm cov phab ntsa hauv pods mus rau cov noob tsim thiab ncua kev degradation ntawm chlorophyll nyob rau hauv lub pods, yog li ncua lub sij hawm tom qab sau qoob loo ntawm cowpeas.
3. Taum dav
Thaum lub sij hawm kev loj hlob thiab kev loj hlob ntawm cov taum broad, daim ntawv thov ntawm low-concentration cog kev loj hlob regulators tsis tsuas yog txhawb kev loj hlob thiab kev loj hlob tab sis kuj tiv thaiv paj thiab pod abscission, inhibits apical dominance, thiab txhim kho cov nroj tsuag txias kam rau ua thiab chaw nyob, yog li ua tiav lub hom phiaj ntawm nce yield.
Tiv thaiv Abscission
Sodium 1-Naphthyl Acetic Acid (Na-NAA)
Spot-txhaj tshuaj sib xyaw ntawm 10 mg/L Na-NAA thiab 1000 mg/L boric acid ntawm cov ntsiab lus uas buds, paj, los yog pods tab tom mus rau qhov tseem ceeb abscission tuaj yeem txo qis qis thiab nce cov pods tsim. Tom qab daim ntawv thov, qhov nruab nrab ib-ploj yield feem ntau nce los ntawm 15-20 kg, thiab maturity yog siab tshaj 5-7 hnub; qhov no yog ib qho yooj yim, siv tau, kev lag luam, thiab kev ntsuas zoo rau kev nce qoob loo. Lub sijhawm zoo tshaj plaws rau kev txau yog nyob rau hnub overcast lossis thaum yav tsaus ntuj ntawm hnub ci; Thaum txau tag nrho cov nroj tsuag, nws yog qhov zoo tshaj plaws los coj cov tshuaj tsuag mus rau hauv qab ntawm nplooj.
Nce yield
Paclobutrazol (Paclo)
Txau 200-300 mg/L Paclobutrazol (Paclo) thaum lub sij hawm taum broad pib flowering mus rau tag nrho-bloom theem ua rau ib tug tseem ceeb nce nyob rau hauv yield. Raws li kev sim ua los ntawm cov koom haum cuam tshuam, daim ntawv thov ntawm Paclobutrazol tuaj yeem txhawb nqa tawm los ntawm 18.5%; Tom qab ntawv thov, cog qhov siab feem ntau txo qis li ntawm 15 cm, ceg tuab nce los ntawm 21.2%, thiab cov pods ib tsob nroj nce 12.6%.
Hais txog cov txheej txheem thov, yuav tsum ua tib zoo saib xyuas lub sijhawm; txau ntxov dhau los yog lig dhau lawm yuav cuam tshuam cov txiaj ntsig ntawm kev kho mob. Rau cov teb uas nthuav tawm kev loj hlob tsis zoo, cov khoom yuav tsum tau siv me ntsis lossis zam tag nrho; conversely, rau cov teb uas qhia ib tug nyiam mus rau qhov chaw nyob, qhov concentration yuav nce mus rau 400 mg/L. Tsis tas li ntawd, tom qab daim ntawv thov, cov neeg cog qoob loo yuav tsum tsis txhob so lawv txoj kev tswj hwm ntawm cov chiv thiab dej - txawm tias cov nplooj tuaj yeem tshwm xim ntsuab - vim tias kev noj zaub mov kom zoo thiab kev tswj hwm noo noo tseem ceeb heev.
Sodium Nitrophenolates
Siv cov tshuaj 6-9 mg/L Sodium Nitrophenolates ib zaug ib zaug thaum lub sij hawm seding theem, puv-bloom theem, thiab pod-teeb theem ntawm broad taum yuav ntxiv dag zog rau seedlings thiab nce yield.
Germination Promotion
Txhawm rau kom ceev cov noob germination ceev thiab nce qhov germination tus nqi - yog li ua kom cov nroj tsuag zoo ib yam thiab ruaj khov - cov noob feem ntau tuaj yeem tsau rau 6 teev hauv ib qho kev daws teeb meem hauv qab no: Gibberellic Acid ntawm 200–300 mg / L, Sodium Nitrophenolates ntawm 6–8 mg/Leth-1-6-Diethyl 2 amino acids ntawm 6–8 mg/Leth-10–1DA amino acid. mg/L. Tag nrho peb txoj kev ua tau zoo ua tiav qhov txiaj ntsig no.
