Betaine (kunyanya glycine betaine), semushonga unokurudzira kukura kwezvirimwa, ine mhedzisiro yakakura mukuvandudza kusimba kwezvirimwa (sekusanaya kwemvura, kusamira kwemunyu, uye kusamira kwechando). Nezvekushandiswa kwayo mukudzivirira kutsemuka kwemichero, tsvakiridzo nemaitiro zvakaratidza kuti ine mhedzisiro yakati, kunyanya nekudzora mashandiro emuviri wezvirimwa kuderedza kutsemuka kwemichero.

Maitiro makuru ekuita kwe betaine mukudzivirira kuputika kwemichero:
1. Osmotic regulation effect
Betaine chinhu chakakosha chinodzora osmotic mumasero emiti chinobatsira kuchengetedza osmotic balance. Munguva yekukura kwemichero nekukurumidza kana panosangana nekuchinja kukuru kwehuwandu hwemvura (senge mvura inonaya kamwe kamwe mushure mekusanaya kwemvura), betaine inogona kudzikamisa kumanikidzwa kwemasero osmotic, kuderedza kusawirirana pakati pekukura kwemuchero wemichero uye kukura kweganda kunokonzerwa nekunwa mvura nekukurumidza, uye nokudaro kuderedza njodzi yekutsemuka kwemichero.
2. Kuvandudza kugadzikana kwemembrane yesero
Betaine inogona kuchengetedza chimiro uye mashandiro emasero, kuderedza kukuvara kwemasero kunokonzerwa nematambudziko (akadai sekupisa kwakanyanya uye kusanaya kwemvura), kuwedzera kusimba uye kuwedzera kwemakanda emichero, uye kuita kuti makanda emichero akwanise kutsungirira kuchinja kwekumanikidzwa kwemukati.
3. Dziviriro yeAntioxidant
Kutsemuka kwemichero kunowanzobatanidzwa nekushushikana kwe oxidative. Betaine inogona kuwedzera mashandiro ema enzymes e antioxidant (akadai seSOD, POD, CAT) mumiti, kubvisa huwandu hwakawanda hwe reactive oxygen species (ROS), kuderedza kukuvara kwe oxidative mumasero, uye kuchengetedza hutano hwemasero emichero.
4. Kurudzira kutorwa kwecalcium uye kutakurwa kwayo
Calcium chinhu chakakosha pamadziro emasero mumakanda emichero, uye kushomeka kwecalcium kunogona kukonzera makanda emichero asina kusimba. Betaine inogona kuvandudza kupenya kwemasero, kukurudzira kutakurwa nekuunganidzwa kwemaion ecalcium kuenda kumakanda emichero, uye kuwedzera simba reganda remichero.
5. Kudzora kuenzana kwemahormone
Zvichikanganisa zvakananga kugadzirwa uye kuburitswa kwezviratidzo zvemahormone emukati (akadai seABA ne ethylene) mumiti, zvichinonotsa kukwegura kwemakanda emichero, uye kuchengetedza kukura kwemakanda emichero.

Mhedzisiro chaiyo yekushandisa:
1. Zvirimwa zvinoshanda:

Inoshandiswa zvakanyanya pazvirimwa zvemichero zviri nyore kutsemuka zvakaita semazambiringa, macheri, madomasi, citrus, uye madate, kunyanya pamhando dzinobatwa nemvura dzakadai seSunshine Rose grapes nemacheri.
2. Kudzivirira kutsemuka:
Kuedza kwemunda kwakaratidza kuti kushandiswa kwe betaine (0.1% ~ 0.3% yakawanda) kunogona kuderedza kutsemuka kwemichero ne20% ~ 40%, uye mhedzisiro yacho inosiyana zvichienderana nerudzi rwezvirimwa, mamiriro ekunze, uye matanho ekutarisira.
Kana ikashandiswa pamwe chete ne calcium fertilizers (yakadai se sugar alcohol calcium uye amino acid calcium), mhedzisiro yacho iri nani, zvichiita kuti pave ne "permeation regulation" mbiri dzinodzivirira "permeation regulation" + structural strength".

Mazano ekushandisa:
Nguva yekushandisa: Pfapfaidza kaviri kana katatu mazuva ese manomwe kusvika gumi kubva pakutanga kwekuzvimba kwemuchero kusvika panguva yekuchinja kweruvara.
Kudzivirira matambudziko asati aitika:

Kupfapfaidza mazuva matatu kusvika mashanu mvura isati yanaya kana kuti kusanaya kwemvura nguva dzose kunofungidzirwa kuti kuchawedzera kugona kwekudzivirira matambudziko.

Kuwanda kunokurudzirwa pakupfapfaidza mashizha: 0.1%~0.3% (kureva 1-3 gramu/rita remvura) kudzivirira kushushikana kwemunyu pamashizha kunokonzerwa nekuwanda kwemvura.
Kudiridza midzi: 0.05%~0.1%, zvichienderana nekutarisira mvura.
Chirongwa chekubatanidza:
Fetereza yeBetaine+calcium (yakadai se calcium ine shuga): inowedzera kusimba kweganda.
Fetereza yeBetaine+boron: inokurudzira kunyudzwa kwecalcium mumuviri uye inoderedza matambudziko emuviri.
Betaine + sora remugungwa: rinowedzera simba rekudzivirira kushushikana.

Zvinhu zvinoda kutariswa:
Kutarisira mvura ndiyo hwaro hwezvinhu zvinotevera:Betaine haigone kutsiva kudiridza kwesainzi! Zvakakosha kuchengetedza hunyoro hwakagadzikana muvhu (senge kuisa purasitiki, kudiridza nemadonhwe) uye kudzivirira kuchinjana kwemvura nekukurumidza.
Kuenzana kwezvekudya:Iva nechokwadi chekuti potassium, calcium, boron nezvimwe zvinhu zvirimo zvine mwero, uye usashandise fetereza yenitrogen nenzira yakarerekera.
Kuenderana kwezvakatipoteredza: Betaine haina chepfu, yakachengeteka kunharaunda nemichero, uye yakakodzera kudyara miti yakasvibira.

Pfupiso:
Betaine inobudirira kusimbisa kusimba kwemichero kuburikidza nenzira dzakasiyana-siyana dzakadai sekutonga kwe osmotic, kugadzikana kwe membrane, kushanda kwe antioxidant, uye kukurudzira kunyudzwa kwe calcium. Sechiyero chekuwedzera, zvakakosha kusanganisa matanho akakwana akadai sekutarisira mvura uye kutonga kwezvinovaka muviri kuti kuderedze zvakanyanya mwero wekupwanyika kwemichero.

Mukushandisa kwakakodzera, zvinokurudzirwa kupfapfaidza zvishoma kakawanda panguva yekuzvimba kwemichero, uye kukoshesa kusanganiswa kwe calcium ne boron fertilizers kuti uwane mhedzisiro yakanaka yekudzivirira kutsemuka kwemichero.
