Kev tshawb fawb tsis ntev los no los ntawm Teagasc, University College Cork (UCC), Ireland, thiab cov neeg koom tes thoob ntiaj teb qhia tias kev sib txawv ntawm cov nroj tsuag hauv cov nyom nyom muaj txiaj ntsig zoo hauv kev txhim kho cov khoom lag luam ntau dua li siv cov kab mob microbial. Txoj kev tshawb no, coj los ntawm Dr. Fiona Brennan, Tus Thawj Saib Xyuas Kev Tshawb Fawb Senior ntawm Teagasc Environment Research Center, Johnstown Castle, Wexford, tau luam tawm hauv phau ntawv journalNroj tsuag thiab av.
Kev tshawb fawb pom tau hais tias kev sib xyaw cov legumes thiab tshuaj ntsuab rau hauv kev tswj hwm kev tswj hwm tau zoo txhim kho cov khoom noj khoom haus thiab cov qoob loo cog qoob loo piv rau kev siv cov microbial inoculants, tseem hu ua bioinoculants. Cov kev tshawb pom no muab kev nkag siab zoo rau cov neeg ua liaj ua teb txhawm rau txo qis cov khoom siv chiv thaum tswj cov qoob loo siab.
Dr. Brennan qhov kev sim ob xyoos tau soj ntsuam qhov ua tau zoo ntawm yim kev kho mob microbial inoculant, suav nrog cov kab mob thiab cov kab mob arbuscular mycorrhizal fungal (AMF) inoculants. Cov kev kho mob no tau siv rau cov noob los yog noob ntawm peb hom nyom nyom: nyom-tsuas, nyom-clover, thiab rau-hom sib xyaw ntawm nyom, clover, thiab tshuaj ntsuab. Tag nrho cov swards tau txais 100 kilograms ntawm nitrogen ib hectare ib xyoo nyob rau hauv daim ntawv ntawm kev tiv thaiv urea.
Raws li Dr. Israel Ikoyi, tus kws qhia UCC thiab yav dhau los tus kws tshawb fawb postdoctoral nrog Teagasc, txoj kev tshawb fawb pom tias cov khoom sib xyaw (cov nyom-legume thiab nyom-legume-tshuaj ntsuab) ua rau muaj kev noj qab haus huv ntau ntxiv thiab tawm los piv rau cov nyom-tsuas yog swards. Tshwj xeeb, hloov ntawm cov nyom-tsuas yog nyom-legume swards nce yields los ntawm 3932 kilograms ib hectare ib xyoo, thaum nyom-legume-tshuaj ntsuab swards nce yields los ntawm 4693 kilograms ib hectare ib xyoos twg. Cov microbial inoculants ntsuam xyuas tsis cuam tshuam rau kev tawm los.
Cov txiaj ntsig no nce ntxiv qhia tias muaj peev xwm nitrogen chiv txuag ntawm 97-117 kilograms ib hectare ib xyoos twg, sawv cev txo nqi rau cov neeg ua liaj ua teb. Dr. Karen Daly, tus thawj coj ntawm Teagasc Environment Research Department, tau hais txog qhov tseem ceeb ntawm cov pov thawj kev tshawb fawb muaj zog hauv kev taw qhia txog kev txiav txim siab txog kev tswj hwm thaj av.
Zuag qhia tag nrho, kev tshawb fawb qhia tau hais tias kev sib xyaw ntawm cov legumes thiab tshuaj ntsuab rau hauv cov nyom nyom yog ib lub tswv yim zoo dua rau kev txhawb nqa cov qoob loo thiab kev noj zaub mov zoo piv rau kev siv cov kab mob microbial inoculants. Txoj hauv kev no muab cov tswv yim daws teeb meem rau cov neeg ua liaj ua teb tab tom nrhiav kev txhim kho cov khoom tsim tau thiab txo qis kev cia siab rau cov chiv, thaum kawg txhawb kev tswj cov nyom kom ruaj khov.
