Yuav txhim kho cov xim txiv hmab txiv ntoo li cas?

Thaum lub sij hawm tus txheej txheem ntawm cov txiv hmab txiv ntoo hloov xim, chlorophyll maj mam lov thiab disappears nyob rau hauv qhov kev txiav txim ntawm hydrolases; qib carotenoid nce me ntsis, thaum anthocyanins raug tsim nyob rau hauv ntau qhov ntau thiab sib sau tsis tu ncua.

Raws li cov txiv hmab txiv ntoo ripens, nws cov xim hauv av feem ntau txiav txim siab los ntawm carotenoids (nrog rau qee qhov seem, tsis tiav degraded chlorophyll), thaum anthocyanins txiav txim siab xim xim. Yog li ntawd, tus yuam sij rau kev txhim kho cov txiv hmab txiv ntoo xim yog nyob rau hauv boosting lub tsub zuj zuj ntawm carotenoids thiab anthocyanins.

I. Yuav ua li cas kom carotenoid tsub zuj zuj?

Carotenoids yog cov xim photosynthetic pom nyob rau hauv chloroplasts (cov nroj tsuag cov kab mob photosynthetic). Ua kom cov ntsiab lus chloroplast nce ntxiv thiab txhim kho cov photosynthetic kev ua tau zoo ntawm nplooj thiab cov txiv hmab txiv ntoo hluas tuaj yeem txhawb nqa qib carotenoid hauv cov txiv hmab txiv ntoo.

II. Yuav ua li cas thiaj li tsim tau anthocyanin?

Anthocyanins yog dej-soluble pigments. Lawv cov synthesis pib thaum cov piam thaj hauv cov txiv hmab txiv ntoo nce mus txog qhov tseem ceeb, nrog rau kev tsim cov tshuaj endogenous tshwj xeeb - tshwj xeeb tshaj yog abscisic acid thiab ethylene. Tsis tas li ntawd, lub teeb raug thiab qhov sib npaug ntawm cov ntxhia hauv lub cev yog qhov tseem ceeb cuam tshuam rau kev tsim cov tshuaj anthocyanin.

III. Yuav ntsuas dab tsi los txhawb cov xim txiv hmab txiv ntoo?

1. Txhim kho lub teeb pom kev zoo

Kev cog qoob loo kom ceev: Khaws qhov sib nrug ntawm cov nroj tsuag thiab kab kom ua kom cov nplooj saum npoo kom pom qhov kaj;

Pruning kom zoo: Tsim kom muaj lub hauv paus qhib ntawm cov ceg ntoo kom txhim kho lub teeb nkag mus rau hauv cov ntoo;

Cov nplooj tshem tawm, hloov cov txiv hmab txiv ntoo, thiab kev cuam tshuam mulching: Ua kom lub teeb ncav cuag cov txiv hmab txiv ntoo thiab zaub kom muaj xim.

2. Sib npaug khoom noj khoom haus

Rational fertilization: Siv chiv scientifically kom muaj kev noj qab haus huv zoo. Qhov no boosts cog vigor, txhim kho photosynthetic efficiency, thiab txhawb cov piam thaj tsub zuj zuj, yog li ua tau raws li tej yam kev mob uas yuav tsum tau rau anthocyanin synthesis. Feem ntau, tsawg nitrogen thiab phosphorus theem ua ke nrog cov poov tshuaj ntau txaus nyiam xim; Tsis tas li ntawd, foliar supplementation nrog calcium, magnesium, thiab cov ntsiab lus tsis tshua muaj hauv ntiaj teb tuaj yeem txhim kho xim kev loj hlob ntxiv. Khoom noj khoom haus ntxiv: Foliar siv sucrose, qabzib, lossis galactose tuaj yeem txhawb cov txiv hmab txiv ntoo xim. Tsis tas li ntawd, cov tshuaj tsuag foliar uas muaj cov tshuaj xws li chitin, chitosan, chitooligosaccharides, anthocyanins, carotenoids, cov kab mob photosynthetic, methyl jasmonate, glutamic acid, molybdenum-amino acid complexes, los yog tryptophan tuaj yeem txhawb kev tsim cov txiv hmab txiv ntoo anthocyanin thiab pab tsim cov xim anthocyanin.

3. Kev tswj ntawm cov nroj tsuag loj hlob Regulators

Feem ntau siv cov regulators los txhawb cov txiv hmab txiv ntoo xim thiab ripening muaj xws li abscisic acid (ABA), 6-BA, thiab ethephon, nrog ethephon yog feem ntau siv.
