Sidee loo horumarin karaa midabka miraha?

Inta lagu jiro habka isbeddelka midabka miraha, chlorophyll si tartiib tartiib ah ayuu u burburaa wuxuuna u baaba'aa ficilka hydrolases; Heerarka carotenoidku wax yar baa kordha, halka anthocyanins laga soo saaro tiro badan oo si joogto ah u urura.

Marka midhaha bislaado, midabkeeda dhulka waxaa ugu horayn go'aamiya carotenoids (oo ay weheliyaan qaar ka haraaga, chlorophyll aan dhammaystirnayn), halka anthocyanins ay go'aamiyaan midabka dusha sare. Sidaa darteed, furaha kor u qaadista midabaynta miraha waxay ku jirtaa kor u qaadida uruurinta carotenoids iyo anthocyanins.

I. Sidee loo kordhin karaa ururinta carotenoid?

Carotenoids waa pigments photosynthetic oo laga helo chloroplasts (xubnaha sawir-qaadista ee dhirta). Kordhinta maadada chloroplast iyo kor u qaadida waxqabadka photosynthetic ee caleemaha iyo midhaha da'da yar waxay kor u qaadi kartaa heerarka carotenoid ee midhaha soo koraya.

II. Sidee loo horumarin karaa wax soo saarka anthocyanin?

Anthocyanins waa midabada biyaha ku milma. Soosaarkoodu waxa uu bilaabmaa marka ururinta sonkorta ee midhaha ay gaadho heer aad u xun, oo ay la socoto soo saarista hormoono gaar ah oo endogenous - gaar ahaan abscisic acid iyo ethylene. Intaa waxaa dheer, soo-gaadhista iftiinka iyo isu-dheellitirka walxaha macdanta ee unugyada ayaa ah arrimo muhiim ah oo saameeya wax soo saarka anthocyanin.

III. Tallaabooyinkee ayaa la qaadi karaa si kor loogu qaado midabaynta miraha?

1. Hagaajinta xaaladaha iftiinka

Cufnaanta beerashada macquulka ah: Joogto fogaanta ku habboon ee u dhaxaysa dhirta iyo safafka si aad u kordhiso bedka caleenta iftiinka;

Goynta saxda ah: Samee qaab-dhismeedka furan ee laamo isku dhejis ah si loo hagaajiyo dhexgalka iftiinka gudaha saqafka;

Ka saarida caleenta, rogrogmida midhaha, iyo milicsiga mulching: Kordhi tirada iftiinka gaadhaya midhaha iyo khudaarta si kor loogu qaado midabaynta.

2. Dheelitirka nafaqada

Bacriminta macquulka ah: Si cilmiyaysan u mari bacriminta si aad u hubiso nafaqo dheeli tiran. Tani waxay kor u qaadaysaa firfircoonida dhirta, waxay wanaajisaa waxtarka photosynthetic, waxayna kor u qaadaa ururinta sonkorta, taas oo buuxinaysa shuruudaha looga baahan yahay isku-darka anthocyanin. Guud ahaan, heerarka nitrogen iyo fosfooraska hooseeya oo ay weheliyaan heerarka potassium sare waxay door bidaan midabaynta; Intaa waxaa dheer, kabitaan foliar ah oo leh kalsiyum, magnesium, iyo walxaha dhifka ah ee dhulka ayaa sii kordhin kara horumarka midabka. Nafaqada Dheeraadka ah: Codsiga foliar ee sukrose, gulukoos, ama galactose waxay kor u qaadi kartaa midabaynta miraha. Intaa waxaa dheer, buufinta foliar ee ay ku jiraan walxaha sida chitin, chitosan, chitooligosaccharides, anthocyanins, carotenoids, bakteeriyada photosynthetic, methyl jasmonate, glutamic acid, molybdenum-amino acid complexes, ama tryptophan waxay kicin karaan samaynta anthocyanin waxayna caawin karaan midabaynta miraha.

3. Nidaaminta iyada oo loo marayo Nidaamiyeyaasha Kobaca Dhirta

Nidaamiyeyaasha sida caadiga ah loo isticmaalo kor u qaadista midabka miraha iyo bislaanshaha waxaa ka mid ah abscisic acid (ABA), 6-BA, iyo ethephon, iyadoo ethephon ay tahay tan ugu badan ee la isticmaalo.
