Cov Ntaub Ntawv Thov ntawm Hydroponics Kev Lag Luam hauv Brazil

Ib lub tuam txhab zaub hydroponic hauv Brazil uas ntes tau pH thiab conductivity ntawm cov tshuaj hauv lub twj tso kua mis peristaltic kom ntseeg tau tias qhov concentration ntawm cov tshuaj lom neeg xav tau thaum lub sijhawm loj hlob zaub yog nyob rau hauv qhov ntau thiab tsawg tsim nyog. Rau cov zaub hydroponic, qhov pH tsim nyog feem ntau yog ntawm 5.5-6.5, pH tus nqi qis dhau yuav ua rau cov hlau ions yaj tsis zoo hauv cov tshuaj nutrient, cuam tshuam rau kev nqus cov as-ham los ntawm zaub; thaum pH tus nqi siab dhau yuav ua rau muaj ntau cov nroj tsuag loj hlob inhibitory hauv cov tshuaj nutrient, cuam tshuam rau kev loj hlob ib txwm ntawm cov zaub. Qhov ntau thiab tsawg tswj conductivity feem ntau yog ntawm 1.5ms / cm thiab 2.5ms / cm, thaum lub sijhawm no, conductivity tuaj yeem cuam tshuam qhov concentration ntawm ions hauv cov tshuaj, kom ntseeg tau tias kev loj hlob ib txwm ntawm cov zaub hydroponic. Qhov ntau thiab tsawg tswj conductivity tshwj xeeb yuav tsum tau txiav txim siab raws li ntau hom zaub, theem kev loj hlob thiab cov xwm txheej ib puag ncig. Feem ntau, rau cov zaub uas muaj lub sijhawm loj hlob ntev, xws li zaub xas lav, celery thiab lwm yam, nws yog qhov tsim nyog dua los tswj conductivity ntawm 1.5ms / cm thiab 2.0ms / cm; rau cov zaub uas muaj lub sijhawm luv luv loj hlob, xws li zaub qhwv Suav, zaub paj ntsuab thiab lwm yam, nws yog qhov tsim nyog dua los tswj qhov conductivity ntawm 2.0ms / cm thiab 2.5ms / cm.
