Taw qhia ntawm CPPU

Forchlorfenuron tseem hu ua CPPU.CAS Nr.yog 68157-60-8.

Chlorophenylurea nyob rau hauv cov nroj tsuag kev loj hlob regulator (CPPU nyob rau hauv cov nroj tsuag kev loj hlob regulator) tuaj yeem txhawb kev faib cell, tsim cov khoom nruab nrog cev thiab cov protein synthesis.Nws tseem tuaj yeem txhim kho photosynthesis thiab tiv thaiv abscission ntawm cov txiv hmab txiv ntoo thiab paj, yog li txhawb cov nroj tsuag kev loj hlob, thaum ntxov maturity, ncua lub senescence ntawm nplooj nyob rau hauv lub tom ntej theem ntawm cov qoob loo thiab nce yield.

 Lub luag haujlwm tseem ceeb ntawm CPPU yog raws li hauv qab no:

1. Txhawb kev loj hlob ntawm qia, nplooj, hauv paus thiab txiv hmab txiv ntoo.Yog tias nws siv rau hauv kev cog qoob loo, nws tuaj yeem ua rau nplooj nplooj hypertrophy thiab nce yield.

2. Txhawb nqa txiv hmab txiv ntoo.Nws tuaj yeem ua rau cov qoob loo ntau ntxiv ntawm cov txiv lws suav (txiv lws suav), eggplant, kua thiab lwm yam txiv hmab txiv ntoo thiab zaub.

3. Ceev cov txiv hmab txiv ntoo thinning.Txiv hmab txiv ntoo thinning yuav ua rau kom cov txiv hmab txiv ntoo tawm los, txhim kho zoo thiab ua kom cov txiv hmab txiv ntoo loj sib xws.

4. Ceev defoliation.Rau paj rwb thiab soybeans, defoliation ua rau sau yooj yim dua.

5. Ua kom muaj suab thaj hauv beet, qab zib, thiab lwm yam.

Thaum siv CPPU, xyuam xim rau cov ntsiab lus hauv qab no:

a.Thaum siv rau cov ceg tsis muaj zog ntawm cov laus, tsis muaj zog, cov nroj tsuag muaj kab mob los yog cov txiv hmab txiv ntoo tsis muaj zog, cov txiv hmab txiv ntoo loj yuav tsis o loj heev;Txhawm rau kom ntseeg tau cov khoom noj uas xav tau rau cov txiv hmab txiv ntoo o, cov txiv hmab txiv ntoo thiab zaub yuav tsum tau siv, thiab cov txiv hmab txiv ntoo yuav tsum tsis txhob ntau dhau.

b.CPPU nyob rau hauv cov nroj tsuag kev loj hlob regulator yog siv rau cov txiv hmab txiv ntoo teeb, tsuas yog rau flowering thiab txiv hmab txiv ntoo ua.Nws yuav tsum tau siv nrog ceev faj ntawm melons thiab watermelons, tshwj xeeb tshaj yog thaum lub concentration siab, nws yog ib qho yooj yim los tsim cov kev mob tshwm sim xws li melon melting, iab saj, thiab tom qab tawg ntawm melon.

c.Cov nyhuv ntawm kev sib xyaw forchlorfenuron nrog gibberellin lossis auxin yog qhov zoo dua li kev siv ib zaug, tab sis nws yuav tsum tau ua raws li kev taw qhia ntawm cov kws tshaj lij lossis nyob rau hauv qhov chaw ntawm thawj qhov kev sim thiab ua qauv qhia.Tsis txhob siv arbitrarily.

d.Yog hais tias lub siab concentration ntawm CPPU cog kev loj hlob regulator tau siv rau txiv hmab txiv ntoo, soluble khoom cov ntsiab lus yuav txo tau, lub acidity yuav nce, thiab cov xim thiab ripening ntawm grapes yuav ncua.

e.Rov ua dua thaum nag los hauv 12 teev tom qab kho.
