University City, Pennsylvania — Cov nplej caij ntuj no feem ntau cog rau ntawm cov liaj teb qaib hauv thaj av Mid-Atlantic ntawm Tebchaws Meskas rau kev tsim cov nplej thiab cov quav ciab. Cov nplej no siv ua zaub mov rau tsiaj, thiab cov quav ciab siv ua chaw pw. Kev sivcov tshuaj tswj kev loj hlobtuaj yeem ua rau cov qoob loo ntau ntxiv los ntawm kev tswj kev loj hlob ntsug thiab txo qhov kev pheej hmoo ntawm kev pw, ib qho mob uas ua rau cov qoob loo tsawg dua. Txawm li cas los xij, cov nyhuv ntawm cov neeg tswj kev loj hlob ntawm cov qoob loo thiab qhov zoo ntawm cov quav nyab tseem tsis meej. Yog li ntawd, ib pab pawg tshawb fawb los ntawm Pennsylvania State University tau ua ib txoj kev tshawb fawb los soj ntsuam cov teebmeem ntawmkev sib xyaw ua ke ntawm cov tshuaj tswj kev loj hlobnrog rau cov nqi siv chiv nitrogen sib txawv. Kev tshawb fawb no tau ua nyob rau hauv kev sim ua teb nplej lub caij ntuj no ntawm Russell E. Larson Agricultural Research Center ntawm Pennsylvania State University.
"Cov neeg ua liaj ua teb tsis xav kom cov nplej loj hlob dhau thiab ua rau cov nplej puas tsuaj, yog li ntau tus neeg ua liaj ua teb tau siv cov tshuaj tswj kev loj hlob ntawm cov nroj tsuag ntev lawm," Daniela Carrijo, tus xibfwb qhia txog kev tsim cov nplej thiab kev nthuav dav hauv College of Agricultural Sciences ntawm Pennsylvania State University hais. "Peb paub tias cov tshuaj tswj kev loj hlob ntawm cov nroj tsuag tuaj yeem txo qhov kev pheej hmoo ntawm kev ua rau cov nplej loj hlob thiab ua rau cov nplej ntau ntxiv, tab sis cov neeg ua liaj ua teb thiab qee tus neeg koom tes xav paub lawv qhov cuam tshuam rau cov qoob loo thiab cov quav nyab zoo. Qhov no yog ib qhov project uas muaj txiaj ntsig zoo, thiab peb tau sim cov khoom siv feem ntau hu ua tricyclazole ethyl ester los txiav txim siab nws qhov cuam tshuam rau cov qoob loo thiab cov quav nyab zoo, uas tseem ceeb rau cov liaj teb sib xyaw ua ke."
Tau ntau tshaj ob xyoos, cov kws tshawb fawb tau sim cuaj qhov kev sib xyaw ua ke ntawm peb qhov kev siv chiv nitrogen thiab peb qhov kev kho tricyclazole ethyl ester. Lawv pom tias tricyclazole ethyl ester txo qhov siab ntawm cov nroj tsuag tab sis tsis ua rau cov qia tuab dua. Ob qhov kev kho tricyclazole ethyl ester ua rau cov qoob loo tsawg dua 8%, thaum ib qho kev kho tsuas yog txo cov qoob loo tsawg dua 5%, txawm hais tias qhov sib txawv no tsis tseem ceeb. Lawv kuj pom tias tricyclazole ethyl ester tsis hloov pauv qhov zoo ntawm cov qoob loo lossis kev nqus dej - txhais tau tias nws tsis cuam tshuam rau lub peev xwm ntawm cov qoob loo kom khaws dej, yog li cov qoob loo tseem tuaj yeem siv ua chaw pw rau tsiaj. Cov kws tshawb fawb tau tshaj tawm tias tsis pom muaj kev pw hauv ib qho ntawm cov phiaj xwm sim, thiab kev siv chiv nitrogen ntau ntxiv ua rau cov protein ntawm cov noob qoob loo zoo dua.
"Peb cov txiaj ntsig tsis sib xws - peb pom tias tricyclazole ethyl ester yuav txo qhov ntau ntawm cov quav ciab me ntsis, tab sis tsis cuam tshuam rau qhov zoo ntawm cov quav ciab lossis cov qoob loo," Carrijo hais. "Cov neeg ua liaj ua teb siv tricyclazole ethyl ester yuav tsum xav txog qhov zoo thiab qhov tsis zoo: nws yuav pab txo qhov chaw nyob (yog tias qhov no yog teeb meem), tab sis yuav txo qhov ntau ntawm cov quav ciab me ntsis. Qhov kev pauv pauv no tseem ceeb heev yog tias cov quav ciab yog cov khoom lag luam tseem ceeb ntawm kev ua liaj ua teb thiab siv ua chaw pw."

Tam sim no nws yog ib tug kws tshawb fawb tom qab kawm tiav qib siab hauv University of Wisconsin-Madison. Ronald Hoover, tus thawj coj laus hauv Department of Plant Science, kuj tau koom nrog txoj kev tshawb fawb no.
