Txhawm rau txhawb cov txiv hmab txiv ntoo thaum ntxov ripening thiab nce cov teeb meem qhuav tsub zuj zuj ntawm pawg hauv qab no ntawm cov nroj tsuag kev loj hlob regulators tuaj yeem xaiv

1. Ethephon

Muaj nuj nqi: Tso tawm ethylene, ncaj qha txhawb cov txiv hmab txiv ntoo ripening, xim kev loj hlob, thiab softening, li no ho shortening lub maturation lub sij hawm. Nyob rau tib lub sijhawm, nws txhim kho kev hloov pauv ntawm cov khoom siv photosynthetic rau cov txiv hmab txiv ntoo, indirectly boosting qhuav teeb tsub zuj zuj.

Cov qoob loo siv tau: Climacteric txiv hmab txiv ntoo xws li txiv tsawb, txiv lws suav, citrus, mangoes, loquats, thiab lwm yam.
Daim ntawv thov Concentration: ** Feem ntau siv raws li 0.1% -0.3% tov ntawm txiv hmab txiv ntoo txau los yog dipping; yuav tsum tau saib xyuas kom tsis txhob muaj phytotoxicity (piv txwv li, txiv hmab txiv ntoo poob los yog browning los ntawm ntau ntau concentration).


2. Triacontanol

Muaj nuj nqi: Txhim kho cov photosynthesis, nce chlorophyll cov ntsiab lus, thiab txhawb nqa amylase kev ua haujlwm, yog li txhawb nqa cov khoom qhuav thiab ua rau cov qoob loo ua ntej.
Daim ntawv thov: Foliar spray ntawm qhov concentration ntawm 0.5 ppm (piv txwv li, 0.5 mg/L). Rau kev pom zoo, siv ib zaug thaum lub sij hawm pib flowering theem thiab ib zaug thaum lub sij hawm tag nrho Bloom theem.

3. Diethyl aminoethyl hexanoate (DA-6)

Muaj nuj nqi: Ua kom cov photosynthetic nce, txhim kho cov pa roj carbon thiab nitrogen metabolism, thiab qeeb senescence; txhawb nqa thaum ntxov ripening, yield nce, thiab kev txhim kho zoo. Nws yog qhov tsim nyog rau kev siv thoob plaws tag nrho lub voj voog loj hlob thiab tseem siv tau zoo nyob rau hauv qhov kub thiab txias.
Pom zoo Concentration: 10–20 mg/L; Siv los ntawm kev txau 2-3 zaug thaum lub sij hawm cov txiv hmab txiv ntoo hluas thiab cov txiv hmab txiv ntoo expansion theem.

4. Brassinolide

Muaj nuj nqi: Txhawb nqa cell elongation thiab faib, ua kom cov txiv hmab txiv ntoo thiab cov txiv hmab txiv ntoo hnyav, thiab txhim kho cov txiv hmab txiv ntoo uniformity thiab xim; accelerates maturation los ntawm 25% -40%.
Kev Siv Lub Sijhawm: Siv los ntawm kev txau thaum lub sijhawm pib tawg paj, theem cov txiv hmab txiv ntoo hluas, thiab cov txiv hmab txiv ntoo nthuav dav.


5. Forchlorfenuron (KT-30, CPPU)

Muaj nuj nqi: Txawm hais tias feem ntau paub txog kev txhawb nqa cov txiv hmab txiv ntoo loj thiab khaws cov paj thiab txiv hmab txiv ntoo, nws tuaj yeem cuam tshuam ncaj qha rau thaum ntxov ripening thiab kev txhim kho zoo los ntawm kev txhawb nqa ntawm tes faib thiab tswj kev faib cov khoom qhuav. (Faj seeb: Daim ntawv thov ntau dhau tuaj yeem ncua kev tsim xim.)
