Tsis ntev los no, Rizobacter launched Rizoderma, biofungicide rau soybean noob kho hauv Argentina, uas muaj trichoderma harziana uas tswj cov kab mob fungal hauv cov noob thiab av.
Matias Gorski, thoob ntiaj teb biomanager ntawm Rizobacter, piav qhia tias Rizoderma yog tshuaj tua kab mob fungicide tsim los ntawm lub tuam txhab hauv kev koom tes nrog INTA (National Institute of Agricultural Technology) hauv Argentina, uas yuav siv nrog rau cov khoom lag luam inoculant.
Nws tau hais tias "Siv cov khoom no ua ntej tseb tsim cov xwm txheej rau cov taum pauv kom loj hlob hauv ib puag ncig zoo thiab muaj kev tiv thaiv ib puag ncig, yog li ua kom muaj txiaj ntsig zoo thiab txhim kho av ntau lawm," nws hais.
Kev sib xyaw ntawm inoculants nrog biocides yog ib qho kev kho tshiab tshaj plaws siv rau cov taum pauv. Ntau tshaj li xya xyoo ntawm kev sim teb thiab ib lub network ntawm kev sim tau pom tias cov khoom ua tau zoo los yog zoo dua li cov tshuaj rau tib lub hom phiaj. Tsis tas li ntawd, cov kab mob hauv lub inoculum yog qhov sib xws nrog qee cov kab mob fungal uas siv hauv cov noob qoob loo.
Ib qho ntawm qhov zoo ntawm cov kab mob biologic no yog kev sib xyaw ua ke ntawm peb txoj kev ua haujlwm, uas ib txwm thaiv kev rov tshwm sim thiab kev loj hlob ntawm cov kab mob tseem ceeb tshaj plaws cuam tshuam rau cov qoob loo (fusarium wilt, simulacra, fusarium) thiab inhibits qhov muaj peev xwm ntawm cov kab mob tiv thaiv.
Qhov kom zoo dua no ua rau cov khoom lag luam muaj kev xaiv zoo rau cov tuam txhab thiab cov kws tshaj lij, vim tias cov kab mob qis dua tuaj yeem ua tiav tom qab thawj zaug ntawm foliicide, ua rau kev txhim kho daim ntawv thov.
Raws li Rizobacter, Rizoderma ua tau zoo hauv kev sim thiab hauv lub tuam txhab network ntawm kev sim. Thoob ntiaj teb, 23% ntawm cov noob taum pauv tau kho nrog ib qho ntawm cov inoculants tsim los ntawm Rizobacter.
"Peb tau ua haujlwm nrog cov tuam ntxhab los ntawm 48 lub teb chaws thiab tau ua tiav cov txiaj ntsig zoo heev. Txoj kev ua haujlwm no tso cai rau peb los teb rau lawv cov kev xav tau thiab tsim cov thev naus laus zis inoculation uas yog qhov tseem ceeb rau kev tsim khoom, "nws hais.
Tus nqi ntawm daim ntawv thov ntawm inoculants ib hectare yog US $ 4, thaum tus nqi ntawm urea, ib tug industrially tsim nitrogen chiv, yog hais txog US $ 150 mus rau US $ 200 ib hectare. Fermín Mazzini, tus thawj coj ntawm Rizobacter Inoculants Argentina, tau taw qhia tias: "Qhov no qhia tau tias qhov rov qab los ntawm kev nqis peev yog ntau dua 50%. Tsis tas li ntawd, vim muaj kev noj qab haus huv zoo ntawm cov qoob loo, qhov nruab nrab cov qoob loo tuaj yeem nce ntau dua 5%. "
Txhawm rau ua kom tau raws li cov kev xav tau saum toj no, lub tuam txhab tau tsim ib qho inoculant uas tiv taus drought thiab kub kub, uas tuaj yeem ua kom muaj txiaj ntsig ntawm kev kho cov noob nyob rau hauv qhov hnyav hnyav thiab ua rau cov qoob loo nce ntxiv txawm tias nyob hauv thaj chaw muaj kev txwv.
Lub tshuab inoculation hu ua biological induction yog lub tuam txhab cov thev naus laus zis tshaj plaws. Kev siv tshuaj lom neeg muaj peev xwm ua kom muaj cov cim qhia molecular los ua kom cov txheej txheem metabolic ntawm cov kab mob thiab cov nroj tsuag, txhawb kev ua ntej thiab zoo dua nodulation, yog li ua kom muaj peev xwm ntawm nitrogen fixation thiab txhawb kev nqus ntawm cov as-ham uas xav tau los ntawm legumes kom vam meej.
"Peb muab kev ua si tag nrho rau peb lub peev xwm tshiab los muab cov neeg cog qoob loo nrog cov khoom siv kho mob kom ruaj khov dua. Niaj hnub no, thev naus laus zis siv rau thaj chaw yuav tsum muaj peev xwm ua tau raws li cov neeg cog qoob loo qhov kev cia siab rau kev tawm los, thaum tseem tiv thaiv kev noj qab haus huv thiab kev sib npaug ntawm kev ua liaj ua teb ecosystem. ", Matías Gorski xaus lus.
