Cov roj teeb uas tsis muaj mercury pov tseg tsis tas yuav rov siv dua thiab kho tus kheej nrog, lawv puas tuaj yeem tsaws tag nrho nrog lub neej khib nyiab? Chen Bai xyoo, qib tsib ntawm Youfu West Street, Hauv kuv tus kheej, tsis lees paub qhov kev xav no. Lub 5th Nanjing Cov Hluas "Science", tuav los ntawm Pawg Neeg Saib Xyuas Hauv Nroog, tuav ib daim ntawv me me hauv qhov kev tshwm sim, thiab cov menyuam yaus tau sau ntau yam txaus siab. Cov roj teeb pov tseg puas "tsawg kawg"? Chen Bai, nco ntsoov tias tus kws qhia ntawv tau hais hauv chav kawm txuj ci: ib lub roj teeb yog rot hauv av, uas tuaj yeem ua rau 1 square meter av mus tas li siv tus nqi; ib lub pob roj teeb tuaj yeem ua rau 600 tons ntawm dej paug.

Yog li ntawd, nws yeej ib txwm ntseeg tias lub roj teeb pov tseg muaj kev phom sij rau ib puag ncig. Tab sis thaum nws tab tom saib cov ntawv xov xwm, nws pom tias qee cov kws tshaj lij ntseeg tias qhov kev phom sij ntawm cov roj teeb pov tseg tsawg tsawg, thiab txawm tias cov neeg ua haujlwm hais tias cov roj teeb tsis muaj pov tseg tsis tas yuav rov ua dua thiab cuam tshuam nrog lawv, tuaj yeem pov cov khib nyiab hauv tsev. Rau cov kev xav zoo li no, Chen Bai tsis lees paub, thiab los ntawm kev sim.

"Kuv xav kawm txog cov noob germination los ntawm cov roj teeb pov tseg, cia ntau tus neeg nkag siab txog kev puas tsuaj ntawm cov roj teeb pov tseg. "Kev sim ua pov thawj tias lub roj teeb uas tsis muaj mercury tseem ua rau muaj kev phom sij rau Chen Bai xyoo: qhov kev loj hlob ntawm mung taum noob hauv cov dej ntshiab yog 100%, nyob rau hauv qee cov noob taum ntsuab germination tus nqi nyob rau hauv cov kua leaching uas sau tias "tsis tshua muaj mercury zinc manganese", nyob rau hauv ib yam ntawm cov germination tus nqi ntawm mung taum noob nyob rau hauv lub roj teeb 0 yog mercury leaching. 100%, tab sis cov noob hauv kev ntxuav yog lig, thiab cov noob germination yuav nres kev loj hlob, thiab thaum kawg pwm, necrosis. Qhov no tuaj yeem txiav txim siab tias cov roj teeb uas muaj mercury tsawg thiab tsis muaj mercury tsis muaj teeb meem rau kev loj hlob thiab kev loj hlob ntawm mung taum noob.

Los ntawm kev sim, thov nug tus kws qhia ntawv, nrhiav cov ntaub ntawv tseem ceeb, Chen Bai ntseeg tias txhua nqe lus uas tau hais ntau dhau los lossis ua rau lub roj teeb muaj teeb meem yog qhov tsis muaj tseeb. "Peb muaj kev nkag siab qee yam ntawm kev phom sij ntawm cov roj teeb uas siv, tab sis tsis muaj kev ua haujlwm. "Tus" Science Little Dr.

"Lub Koom Haum Koom Tes tau tshuaj xyuas 74 cov ntaub ntawv zoo, uas suav nrog ntau yam kev qhuab qhia xws li haiv neeg, lub neej, thiab tsiaj txhu. Nws tau tshaj tawm tias cov neeg ua si uas muaj kev ua tau zoo hauv cov ntawv me me no thiab cov lus teb yuav tau txais lub npe hu ua 5th Nanjing Juvenile "Science Little Dr."
