Qos Yaj Ywm yog cov qoob loo zoo uas yuav muaj nyob hauv daim teb tshwj tsis yog lawv yuav tshwm sim hauv xyoo thaum lawv tsis xav nyob ntawd, thov cov lus nug - koj yuav ua li cas thiaj li tshem tau lawv?
Spud Ntse (SS): Yuav ua li cas yog volunteer qos yaj ywm?
Gavin Graham (GG): XNUMX Lab tus kiv cua tos koj rau Webtalk! Nws yog tiag tiag tsis yooj yim sua kom tshem tawm tag nrho cov tub thaum lub sij hawm peb cov kev sau qoob loo, nyob ntawm koj qhov loj me, lossis koj cov qoob loo zoo li cas. Qee qhov kev kwv yees yog tias koj tuaj yeem tso tawm txog 10 feem pua ntawm cov qe hauv daim teb. Yog li cov raj no yuav tau mus nyob hauv lub teb thiab cov uas tuaj yeem loj tuaj thaum lub xyoo tom ntej thiab ua cov nyom lossis ua nroj nyob rau xyoo tom qab xyoo hloov, thiab txawm tias yuav sib tw ncaj qha rau cov qoob loo tom ntej no.
Los yog lwm tus, ua tus tswv cuab hloov chaw rau qee qhov ntawm lwm cov kab tsuag lossis kab mob uas peb tab tom soj ntsuam hauv kev tsim cov qos yaj ywm. Qhov no tuaj yeem ua tus choj ua cov kis cov teeb meem nyob ib puag ncig thiab pab lawv nthuav tawm hauv thaj chaw lossis hauv thaj chaw peb sab. Yog li, nws tseem ceeb heev uas yuav tau sim saib kev tswj.
Yog koj tso cov ntawd volunteers kom loj hlob rau lub voj voog tag nrho lossis tag nrho lub caij, lawv tuaj yeem tsim cov tub ntxhais hluas, thiab tom qab ntawd koj lub voj voog yuav cia li rov ua dua. Yog li, nws yog ib qho tseem ceeb uas yuav tau sim tswj cov neeg ntawd thaum koj xub pom lawv thiab sim txwv lawv txoj kev sib kis thiab txwv lawv lub peev xwm coj los muab kev cuam tshuam rau koj tom qab ntawm txoj kev.
SS: Vim li cas lawv tuaj yeem tshem tawm nyuaj?
GG: Volunteer potatoes are not an easy weed to control. They are can be pretty difficult, depending on what your crop rotation looks like and what your following crops are. One of the issues is that these volunteers muaj tus qauv zoo nkauj dav dav. Lawv zoo li tshwm sim nyob rau ntau lub sijhawm thaum lub caij. Thiab qhov no yog tiag tiag tswj los ntawm qhov tob npaum li cas cov tubers nyob rau hauv koj cov av profile.
Raws li kev tswj hwm mus, tsis muaj ib qho kev tswj xyuas tiag tiag lossis cov txheej txheem uas yuav ua haujlwm rau txhua tus. Koj yeej xav tau kev sib koom ua ke ntau lub tswv yim los sim ua ntej ntawm cov nroj tsuag no thiab kev tiv thaiv yog lub hauv paus ntawm txhua yam. volunteer qos yaj ywm tswj kev pab cuam.
Erin Burns (EB): XNUMX Lab tus kiv cua tos koj rau Webtalk! Lawv yog ib tug tsiaj nyaum nyob rau hauv lawv tus kheej nrog rau qhov loj cia cia piv rau ib co ntawm lwm yam nroj tsuag nrog ntau me me noob. Thiab lawv tsuas muaj peev xwm loj hlob sai heev thiab ua rau muaj kev puas tsuaj rau cov qoob loo uas lawv tau sib tw nrog. Thiab tom qab ntawd tshwj xeeb hauv pob kws, thiab hauv ntau lwm cov qoob loo, tsis muaj cov tshuaj tua kab mob uas yuav tswj tau tag nrho. volunteers. Thaum kawg, lub hom phiaj yog kom txo tus naj npawb ntawm cov ntxhais tubers uas tau tsim.
SS: Koj tuaj yeem tshem lawv tawm nrog kev ua agronomic?
GG: Los ntawm a volunteer kev xav, noj qos yaj ywm tawm ntawm thaj teb ntau dua qhov koj yuav zoo dua. Thiab kom ua tau li ntawd, qhov ntawd yog qhov uas koj yuav tsum muaj kev coj ua kom ntseeg tau tias muaj kev sib xws, cov qoob loo zoo, kom koj tuaj yeem tau txais txiaj ntsig zoo tshaj plaws ntawm thaj teb li sai tau. Yog li ntawd los ntawm koj cov noob sib nrug, koj cov noob tswj, ua kom paub tseeb tias koj tau txais cov noob noj qab haus huv, muab txoj cai fertility nyob rau hauv qhov profile loj uas koj tab tom nrhiav, txo cov kev cuam tshuam no.
Thaum koj nkag mus rau hauv qhov sau qoob loo ntawm koj cov qoob loo qos yaj ywm, nco ntsoov tias koj cov chaw sau qoob thiab chaw nrawm tau teeb tsa kom raug. Sim ua kom paub tseeb tias koj qhov siab tshaj plaws cov khoom lag luam uas thim rov qab mus rau hauv lub thoob rau khaws cia, tsis txhob ua rau nchuav hauv lub tshav pob, nco ntsoov tias koj cov tub tau tag nrho tawm ntawm cov qia yog li lawv tsis tau ntes rau ntawm cov hmab thiab mus los ntawm koj cov qoob loo li ntawd. Thiab qhov ntawd ua qhov kev xaiv desiccant tsim nyog yog tias qhov tseem ceeb. Tom qab ntawd lwm qhov kev xaiv yog ib qho infield sprouting inhibitor, peb tau yeej tau dhau ntawm qhov ntawd. Tab sis nws yog ib yam dab tsi los xav txog yog tias koj cov kev lag luam yuav tso cai ntawd.
EB: Ntawm no, tshwj xeeb tshaj yog nyob rau hauv Michigan, peb tau tso siab rau peb cov huab cua txias los tua ib co ntawm cov no volunteers, thiab qhov ntawd tsuas yog tsis tshwm sim ntxiv lawm. Yog li, lawv yuav dhau los ua teeb meem yav tom ntej yog tias koj tsis muaj qhov teeb meem no. Yog li, cov kev tshawb fawb ntawm MSU (Michigan State University) tau pom tias feem ntau cov qos yaj ywm cultivars uas peb loj hlob ntawm no hauv Michigan, tawg tom qab txog ib hnub ntawm qhov raug rau 27 F los yog tsuas yog -2.8 C. Qhov ntawd yog hais txog ib hnub, muab los yog noj. ob peb teev.
SS: Yuav ua li cas koj tshem tawm lawv nyob rau hauv cov zaub mov ua teb? Pob kws teb?
GG: Roundup yog qhov kev kho mob zoo tshaj plaws rau kev tswj kom pom thiab cov ntxhais tuber tawm los. Kuv xav tias Roundup yog qhov kev xaiv khov kho uas peb muaj hauv kev sim. Callisto muaj qee cov regrowth, tab sis muaj qee qhov kev tswj tau zoo ntawm tus ntxhais lub tub. Yog li, rau kev cog pob kws, lossis qee qhov ntawm lwm cov qoob loo uas Callisto muaj daim ntawv lo rau, Kuv xav tias qhov no yog qhov kev xaiv zoo. MCPA amine tsis yog qhov tau txais txiaj ntsig tiag tiag. Tsiv mus rau Pixxaro thiab Trophy puas tau txhim kho qhov pom tau zoo tshaj plaws, tab sis lawv tsis tshua txhim kho thaum kawg cov hmoov av.
Tab sis qhov muaj zog tshaj plaws kom deb li deb raws li qhov kev xav ua kom pom, Infinity, Refine thiab Refine + MCPA yog qhov zoo tshaj plaws raws li kev pom ntawm mus, tab sis me ntsis ntxiv qhov kev txo qis hauv cov tuber yields. Tab sis kev ncaj ncees, txhua yam ntawm cov tshuaj ntsuab tshuaj ntsuab yeej tsis muaj zog npaum li Roundup lossis Callisto tau nyob hauv kev sim siab.
EB: Yog li, qee qhov kev txiav txim siab los ntawm cov kev tshawb fawb uas peb tau ua hauv pob kws yog, tag nrho, ntxiv ntawm atrazine rau cov HPPD inhibitors - yog li, nws yog pawg 27, thoob plaws lub rooj tsavxwm - txhim kho. volunteer qos tswj, raws li qhov loj ntawm volunteer qos yaj ywm nce peb qhov kawg tswj txo...Thiab tom qab ntawd thaum kawg, dab tsi koj yuav siv los tswj volunteers, koj yuav tsum nco ntsoov tias koj cov qoob loo yav tom ntej yog dab tsi los xyuas kom meej tias koj nyob hauv cov kev txwv kev sib hloov.
Yog xav paub ntxiv nyob rau hauv volunteer qos yaj ywm saib peb lub vev xaib kawg ntawm nws.
