Kev ua tau zoo thiab kev ua haujlwm ntawm Chlormequat chloride (CCC) siv hauv cov qoob loo loj hlob

Chlormequat chloride (CCC) yog ib qho antagonist ntawm gibberellins.Nws lub luag haujlwm tseem ceeb yog inhibit biosynthesis ntawm gibberellins.Nws tuaj yeem inhibit cell elongation tsis cuam tshuam rau cell division, inhibit qhov kev loj hlob ntawm stems thiab nplooj tsis cuam tshuam rau kev loj hlob ntawm kev sib deev hauv nruab nrog cev, yog li ua tiav kev tswj hwm. ntawm elongation, tiv taus chaw thiab nce yield.

Yog li dab tsi yog cov haujlwm thiab kev ua haujlwm ntawm Chlormequat chloride (CCC)? Chlormequat chloride (CCC) siv tau li cas rau hauv ntau cov qoob loo? Peb yuav tsum xyuam xim rau dab tsi thaum siv Chlormequat chloride (CCC)?

Kev ua tau zoo thiab kev ua haujlwm ntawm Chlormequat chloride (CCC)
(1) Chlormequat chloride (CCC) txo qhov "kub noj" kev puas tsuaj rau cov noob
Chlormequat chloride (CCC) siv rau hauv kev cog qoob loo.
Thaum qhov kub ntawm cov noob nplej siab tshaj 40 ° C rau ntau tshaj 12 teev, thawj zaug ntxuav lawv nrog dej huv, thiab tom qab ntawd tsau cov noob nrog 250mg / Lchlormequat chloride (CCC) kua rau 48 teev. Cov kua yuav tsum submerge cov noob. Tom qab ntxuav cov tshuaj, germinating ntawm 30 ℃ tuaj yeem txo qhov kev puas tsuaj los ntawm "siv cua sov".

(2) Chlormequat chloride (CCC) los cog cov noob muaj zog
Chlormequat chloride (CCC) siv hauv pob kws loj hlob.
Soak cov noob nrog 0.3% ~ 0.5% tshuaj tov rau 6 teev, daws: noob = 1:0.8, qhuav thiab sow, tsuag cov noob nrog 2% ~ 3% Chlormequat chloride (CCC) tov rau noob hnav khaub ncaws, thiab sow rau 12 teev. , tab sis cov yub muaj zog, lub hauv paus system yog tsim, tillers muaj ntau, thiab cov tawm los yog nce li ntawm 12%.

Txau 0.15% ~ 0.25% tshuaj tov nyob rau thaum ntxov ntawm tillering, nrog ib tug tshuaj ntim ntawm 50kg/667㎡ (qhov concentration yuav tsum tsis txhob siab dua, txwv tsis pub lub taub hau thiab maturity yuav ncua), uas yuav ua rau cov nplej nplej luv luv. thiab muaj zog, nce tillering, thiab nce yield los ntawm 6.7% ~ 20.1%.

Dilute cov noob 80 mus rau 100 zaug nrog 50% dej thiab tsau rau 6 teev. Nws yog advisable kom submerge cov noob nrog cov kua. Qhuav nyob rau hauv ntxoov ntxoo thiab ces sow. Qhov no yuav ua rau cov nroj tsuag luv luv thiab muaj zog, nrog cov hauv paus hniav zoo, cov pob qij qis, tsis muaj taub hau, pob ntseg loj thiab tag nrho cov nplej, thiab cov txiaj ntsig tseem ceeb nce ntxiv. Nyob rau hauv lub caij nplooj ntoos hlav, siv 0.2% ~ 0.3% tshuaj tov thiab tshuaj tsuag 50kg Chlormequat chloride (CCC) txhua 667 square meters. Nws tuaj yeem ua lub luag haujlwm hauv squatting seedlings, tiv thaiv ntsev-alkali thiab drought, thiab nce tawm los ntawm li 20%.

(3) Chlormequat chloride (CCC) inhibits qia thiab nplooj loj hlob, tiv thaiv chaw nyob, thiab nce yield.
Chlormequat chloride (CCC) siv rau hauv kev cog qoob loo.
Txau Chlormequat chloride (CCC) thaum kawg ntawm tillers thiab qhov pib ntawm kev sib koom ua ke tuaj yeem cuam tshuam qhov elongation ntawm internodes ntawm qis qis 1 mus rau 3 ntawm cov qia, uas yog qhov zoo heev los tiv thaiv cov nplej lodging thiab nce pob ntseg. Yog hais tias 1 000 ~ 2 000 mg / Lchlormequat chloride (CCC) yog txau thaum lub sij hawm sib koom ua ke, nws yuav inhibit qhov elongation ntawm internode thiab tseem cuam tshuam rau kev loj hlob ntawm pob ntseg, uas ua rau txo yield.
