DCPTA txhawb nqa cov qos yaj ywm kom loj, ua kom cov hmoov txhuv nplej siab, thiab txhim kho kev lag luam. Nws cov txheej txheem tseem ceeb nyob hauv kev tswj hwm kev faib cov khoom siv photosynthetic thiab txhawb nqa cov pa roj carbon metabolic efficiency.
Txhawb Tuber Enlargement: Los ntawm kev txhim kho nplooj nplooj photosynthetic efficiency thiab nce kev thauj thiab tsub zuj zuj ntawm cov khoom photosynthetic nyob rau hauv tubers, DCPTA ho ntxiv dag zog rau "qhov chaw-rau-sab" thauj muaj peev xwm. Qhov no ua rau sai tuber cell faib thiab nthuav, yog li ua kom cov tubers ib tsob nroj thiab txhim kho tuber uniformity.
Nce Starch Cov ntsiab lus: Cov nroj tsuag loj hlob regulator upregulates cov kev ua ntawm starch synthesis ntsig txog enzymes nyob rau hauv lub tubers - xws li ADP-glucose pyrophosphorylase - pab txhawb kev hloov pauv ntawm carbohydrates rau hauv cov hmoov txhuv nplej siab. Cov txiaj ntsig ntsuas tau qhia tias cov ntsiab lus ntawm cov hmoov txhuv nplej siab tuaj yeem nce ntau dua 10%.
Txhim khu kev lag luam: DCPTA txhim kho tuber daim tawv nqaij smoothness thiab morphological sib xws, thaum txo qhov tshwm sim ntawm cov tubers malformed (xws li, tawg tubers los yog saw tubers). Thaum ua ke nrog kev tswj dej thiab chiv kom zoo, kev lag luam tuaj yeem txhawb nqa los ntawm 15-20%.
Pom zoo daim ntawv thov raws tu qauv:
Foliar Spray Concentration: Thaum lub sij hawm thawj theem ntawm tuber o (los ntawm kev tsim cov paj mus rau paj), thov ib tug ** 20-25 mg/L DCPTA tov ** los ntawm foliar tshuaj tsuag ib zaug txhua 7-10 hnub, rau tag nrho ntawm 2-3 daim ntawv thov sib law liag.
Tank-Mixing Cov Lus Qhia: Rau kev sib koom ua ke - txhawb nqa cov khoom qhuav qhuav thiab kev noj zaub mov zoo - DCPTA tuaj yeem sib xyaw nrog 0.3% monopotassium phosphate lossis chelated kab kawm ** rau kev thov ib txhij.
Kev Ceeb Toom: Tsis txhob siv rau lub sijhawm kub lossis lub hnub ci hnyav kom tiv thaiv kom tsis txhob muaj cov tshuaj tsuag sai sai, uas tuaj yeem cuam tshuam kev nqus dej. Tsis tas li ntawd, ua tib zoo tswj kev siv cov chiv nitrogen kom tsis txhob muaj kev loj hlob ntau dhau (kab thiab nplooj nplooj overgrowth).
