Betaine (feem ntau yog glycine betaine), raws li biostimulant hauv kev ua liaj ua teb, muaj cov txiaj ntsig tseem ceeb hauv kev txhim kho cov qoob loo kev ntxhov siab (xws li drought resistance, ntsev, thiab txias tsis kam). Hais txog nws daim ntawv thov hauv kev tiv thaiv cov txiv hmab txiv ntoo tawg, kev tshawb fawb thiab kev coj ua tau pom tias nws muaj qee yam cuam tshuam, feem ntau yog los ntawm kev tswj cov nroj tsuag lub cev kom txo tau cov txiv hmab txiv ntoo tawg.

Lub luag haujlwm tseem ceeb ntawm kev ua ntawm betaine hauv kev tiv thaiv cov txiv hmab txiv ntoo tawg:
1. Osmotic kev tswj cov nyhuv
Betaine yog ib qho tseem ceeb osmotic regulator nyob rau hauv cov nroj tsuag hlwb uas pab tswj osmotic tshuav nyiaj li cas. Thaum lub sij hawm ntawm cov txiv hmab txiv ntoo loj hlob sai los yog thaum ntsib kev hloov pauv hauv cov ntsiab lus dej (xws li nag los nag heev tom qab drought), betaine tuaj yeem ua kom cov cell osmotic siab, txo qhov tsis sib haum ntawm cov txiv hmab txiv ntoo pulp expansion thiab cov tawv nqaij loj hlob los ntawm kev nqus dej sai, thiab yog li txo qhov kev pheej hmoo ntawm cov txiv hmab txiv ntoo tawg.
2. Txhim kho cell membrane stability
Betaine tuaj yeem tiv thaiv cov txheej txheem thiab kev ua haujlwm ntawm cov cell membranes, txo kev puas tsuaj rau cell membranes tshwm sim los ntawm kev nyuaj siab (xws li kub thiab drought), txhim khu lub toughness thiab extensibility ntawm txiv hmab txiv ntoo peels, thiab ua rau cov txiv hmab txiv ntoo peels muaj peev xwm tiv taus kev hloov hauv siab.
3. Antioxidant tiv thaiv
Txiv hmab txiv ntoo tawg yog feem ntau txuam nrog oxidative kev nyuaj siab. Betaine tuaj yeem txhim kho cov haujlwm ntawm cov enzymes antioxidant (xws li SOD, POD, CAT) hauv cov nroj tsuag, tshem tawm cov pa oxygen ntau dhau (ROS), txo cov cellular oxidative puas, thiab tswj kev noj qab haus huv ntawm cov txiv hmab txiv ntoo tev hlwb.
4. Txhawb kev nqus calcium thiab kev thauj mus los
Calcium yog ib qho tseem ceeb ntawm cov phab ntsa ntawm tes hauv cov txiv hmab txiv ntoo tev, thiab calcium deficiency tuaj yeem ua rau cov txiv hmab txiv ntoo tawg yooj yim. Betaine tuaj yeem txhim kho cell membrane permeability, txhawb nqa kev thauj thiab khaws cov calcium ions rau cov txiv hmab txiv ntoo tev, thiab txhim kho lub zog ntawm cov txiv hmab txiv ntoo tev.
5. Hormonal balance tswj
Indirectly cuam tshuam rau synthesis thiab teeb liab transduction ntawm endogenous cov tshuaj hormones (xws li ABA thiab ethylene) nyob rau hauv cov nroj tsuag, ncua kev laus txheej txheem ntawm cov txiv hmab txiv ntoo peels, thiab tswj cov kev loj hlob ntawm txiv hmab txiv ntoo peels.

Daim ntawv thov tiag tiag:
1.Cov qoob loo siv tau:

Nws yog dav siv rau cov qoob loo tawg yooj yim xws li txiv hmab txiv ntoo, cherries, txiv lws suav, citrus, thiab hnub, tshwj xeeb tshaj yog rau cov dej rhiab heev xws li Sunshine Rose grapes thiab cherries.
2. Kev tiv thaiv kev tawg:
Cov kev sim teb tau pom tias foliar daim ntawv thov ntawm betaine (0.1% ~ 0.3% concentration) tuaj yeem txo cov txiv hmab txiv ntoo tawg ntawm 20% ~ 40%, nrog rau cov teebmeem tshwj xeeb txawv nyob ntawm ntau yam qoob loo, huab cua, thiab kev tswj xyuas.
Thaum siv ua ke nrog calcium chiv (xws li qab zib cawv calcium thiab amino acid calcium), cov nyhuv zoo dua, ua kom muaj kev tiv thaiv dual ntawm "txoj cai permeation + kev txhim kho cov qauv".

Cov lus qhia siv:
Lub sijhawm thov tseem ceeb: Txau 2-3 zaug txhua 7-10 hnub txij thaum pib ntawm cov txiv hmab txiv ntoo o mus rau lub sijhawm hloov xim.
Kev tiv thaiv ua ntej kev nyuaj siab:

tshuaj tsuag 3 ~ 5 hnub ua ntej los nag los nag los yog nag xob nag cua txuas ntxiv tau kwv yees los txhim kho lub peev xwm tiv thaiv kev nyuaj siab.

Kev pom zoo kom siv tshuaj tsuag foliar: 0.1% ~ 0.3% (piv txwv li 1-3 grams / liter dej) kom tsis txhob ntsev ntsev ntawm nplooj los ntawm siab concentration.
Hauv paus irrigation: 0.05% ~ 0.1%, synchronized nrog dej tswj.
Cov txheej txheem sib xyaw:
Betaine + calcium fertilizer (xws li qab zib cawv calcium): ua kom tawv nqaij tawv.
Betaine + boron chiv: txhawb kev nqus calcium thiab txo cov kab mob physiological.
Betaine + seaweed extract: synergistically txhim khu kev nyuaj siab.

Cov teeb meem xav tau kev saib xyuas:
Kev tswj dej yog lub hauv paus:Betaine tsis tuaj yeem hloov cov dej hauv kev tshawb fawb! Nws yog ib qho tsim nyog los tswj cov av noo nyob ruaj khov (xws li tso cov yeeb yaj kiab yas, drip irrigation) thiab zam kom tsis txhob ntub dej hloov pauv sai.
Khoom noj khoom haus Balance:Xyuas kom muaj qhov sib npaug ntawm cov poov tshuaj, calcium, boron thiab lwm yam khoom, thiab tsis txhob siv cov chiv nitrogen.
Environmental compatibility: Betaine yog ib txwm tsis muaj tshuaj lom, muaj kev nyab xeeb rau ib puag ncig thiab cov txiv hmab txiv ntoo, thiab tsim nyog rau kev cog qoob loo ntsuab.

Cov ntsiab lus:
Betaine zoo txhim kho cov txiv hmab txiv ntoo tawg los ntawm ntau txoj hauv kev xws li kev tswj osmotic, txhim kho daim nyias nyias, kev ua haujlwm antioxidant, thiab txhawb kev nqus calcium. Raws li kev ntsuas kev pabcuam, nws yog ib qho tsim nyog los muab cov kev ntsuas dav dav xws li kev tswj hwm dej thiab kev tswj hwm kev noj haus kom txo tau cov txiv hmab txiv ntoo tawg.

Hauv kev siv cov tswv yim, nws raug nquahu kom tshuaj tsuag qis qis ntau zaus thaum lub sijhawm cov txiv hmab txiv ntoo o, thiab ua ntej ua ke nrog calcium thiab boron chiv kom ua tiav qhov zoo tshaj plaws tiv thaiv kab mob.
