DCPTA txhawb nqa tillering thiab pob ntseg tsim nyob rau hauv barley, nce txhiab-grain hnyav, thiab txhim kho cov nplej zoo. Nws yog ib qho kev nyab xeeb thiab muaj txiaj ntsig zoo cog kev loj hlob regulator haum rau kev tswj barley kev loj hlob thoob plaws nws tag nrho cov kev loj hlob voj voog.
Mechanism ntawm Action thiab Core Effects
1. Txhawb nqa Tillering thiab pob ntseg tsim: Los ntawm kev ua kom muaj kev qhia ntawm cov noob muaj feem xyuam rau kev faib ntawm tes, DCPTA ua kom cov tillers nce ntau thiab cov pob ntseg zoo hauv barley. Thaum siv los ntawm cov tshuaj tsuag foliar thaum lub sij hawm sib koom ua ke thaum ntxov, nws txhim kho qhov tseem ceeb ntawm basal qia internodes, txhawb nqa qis-txoj hauj lwm tillers los txhim kho pob ntseg zoo; qhov no tuaj yeem ua rau muaj qhov nce ntawm pob ntseg-cov kabmob ntau dua 15%.
2. Ua Ntau txhiab-Nplooj Nyhav: DCPTA boosts lub photosynthetic tus nqi ntawm tus chij nplooj, ncua nplooj senescence, thiab ncua lub sij hawm sau qoob loo. Nyob rau tib lub sijhawm, nws pab txhawb kev hloov pauv ntawm carbohydrates rau cov nplej, txhim kho cov qoob loo plumpness thiab ntau txhiab-grain hnyav; Cov ntaub ntawv sim qhia tias qhov hnyav nce li ntawm 8% mus rau 12%.
3. Kev Txhim Kho Zoo: Ua raws li kev thov ntawm DCPTA, cov ntsiab lus ntawm cov khoom noj khoom haus-xws li cov protein thiab β-glucan-hauv cov nplej nplej tau nce ntxiv. Raws li qhov tshwm sim, tus nqi ntawm chalkiness (opaque kernels) txo qis, yog li txhim kho kev lag luam ntawm cov qoob loo.
Txhim khu kev ntxhov siab: Nyob rau hauv cov xwm txheej ntawm qhov kub thiab txias, DCPTA pab tswj cov nroj tsuag cov dej sib npaug thiab txhawb kev ua haujlwm ntawm cov enzymes antioxidant (xws li SOD thiab POD). Qhov no mitigates oxidative puas thiab pab kom ruaj khov yields.
Pom zoo daim ntawv thov raws tu qauv
Lub Sijhawm Zoo Tshaj Plaws: Thov ntawm foliar txau ib zaug thaum lub sijhawm * peak tillering theem * thiab ib zaug thaum lub sijhawm * booting theem * kom ua kom lub pob ntseg tsim thiab kev loj hlob.
Daim Ntawv Thov Kev Cuam Tshuam: Cov lus pom zoo rau kev txau cov nplooj yog **20-30 mg/L** (los yog ppm); tsis txhob ntau tshaj 50 mg/L, vim qhov no yuav ua rau kev loj hlob inhibition.
Tank-Mixing Cov Lus Qhia: Rau cov txiaj ntsig zoo, DCPTA tuaj yeem sib xyaw thiab txau ua ke nrog 0.2% monopotassium phosphate lossis nrog cov chiv micronutrient uas muaj zinc thiab boron. Qhov kev sib xyaw ua ke no txhim kho photosynthetic efficiency thiab cov as-ham uptake.
Kev nyab xeeb: DCPTA tsis muaj tshuaj lom thiab tawm tsis muaj teeb meem seem; nws yog ib puag ncig tus phooj ywg thiab nyab xeeb rau tib neeg thiab tsiaj txhu. Nws yog sib xws nrog feem ntau fungicides thiab insecticides, yog li txhim kho kev ua hauj lwm efficiency.
