Lub tuam txhab hydroponic zaub hauv Brazil uas kuaj pom pH thiab conductivity ntawm cov tshuaj nyob rau hauv lub peristaltic twj tso kua mis los xyuas kom meej tias cov concentration ntawm cov tshuaj uas yuav tsum tau thaum lub sij hawm zaub loj hlob nyob rau hauv qhov tsim nyog ntau yam.Rau cov zaub hydroponic, qhov haum pH feem ntau yog nyob nruab nrab ntawm 5.5-6.5, pH tus nqi qis dhau yuav ua rau tsis zoo ntawm cov hlau ions nyob rau hauv cov zaub mov absorption, cuam tshuam rau cov zaub mov absorption. Thaum pH tus nqi siab dhau lawm yuav ua rau muaj ntau cov nroj tsuag kev loj hlob inhibitory tshuaj nyob rau hauv cov zaub mov, cuam tshuam qhov kev loj hlob ntawm cov zaub.Cov kev tswj kev tswj ntau yog feem ntau ntawm 1.5ms / cm thiab 2.5ms / cm, nyob rau hauv no ntau yam, lub conductivity muaj peev xwm cuam tshuam cov concentration ntawm ions nyob rau hauv cov tshuaj, los xyuas kom meej qhov kev loj hlob ntawm hydroponic zaub. Lub sij hawm loj hlob ntev, xws li lettuce, celery thiab lwm yam, nws yog qhov tsim nyog los tswj cov conductivity ntawm 1.5ms / cm thiab 2.0ms / cm; rau cov zaub nrog lub sij hawm loj hlob luv, xws li Suav cabbage, spinach thiab lwm yam, nws yog tsim nyog los tswj cov conductivity ntawm 2.0ms / cm thiab 2.5ms / cm.
Kev siv cov khoom siv:
pHG-2081 Kev lag luam pH ntsuas
DDG-2090 Kev lag luam EC meter
pH-8012 Kev lag luam pH sensor
DDG-0.01 digital EC sensor
Lub tuam txhab zaub hydroponic hauv Brazil tau txhim kho cov khoom noj khoom haus sib npaug ntawm cov zaub thiab nce nws cov khoom tsim los ntawm kev txhim kho pH thiab conductivity. Nws tau txhawb cov neeg siv khoom hydroponic project thiab ua tiav "kev ua haujlwm ntse thiab kev txhim kho kom ruaj khov".
