Center pivot sprinkler (qee zaum hu ua central pivot irrigation), kuj hu ua hluav taws xob ncig sprinkler, pointer hom sprinkler thiab lwm yam, yog ib txoj kev ntawm cov qoob loo irrigation nyob rau hauv uas cov khoom rotates ib ncig ntawm ib tug pivot thiab cov qoob loo yog watered nrog sprinklers.Qhov nruab nrab-pivot irrigation systems tau txais txiaj ntsig vim lawv muaj peev xwm siv dej kom zoo thiab ua kom zoo rau kev ua liaj ua teb.Cov tshuab ua haujlwm tau zoo heev ntawm thaj av loj.
Tsim nyog qoob loos: alfalfa, pob kws, nplej, qos yaj ywm, qab zib beet, cereals thiab lwm yam nyiaj ntsuab qoob loo.
Lub nruab nrab txhawb nqa ncej kawg ntawm lub sprinkler yog tsau, thiab tus so ntawm lub sprinkler txav nyob ib ncig ntawm lub taag kawg tsav los ntawm lub cev muaj zog.Los ntawm qhov kev sib tshuam ntawm qhov kawg ntawm Central ceg ncej, cov dej ntws los ntawm tus dej los yog qhov dej thiab xa mus rau cov yeeb nkab dej ntawm lub tshuab nqus dej, thiab tom qab ntawd xa mus rau qhov chaw los ntawm lub tshuab nqus dej kom paub txog kev siv dej tsis siv neeg.
Ib cheeb tsam ncig ntawm qhov pivot yog irrigated, feem ntau tsim ib ncig ntawm cov qoob loo thaum saib los ntawm saum toj no.
Center-pivot irrigation siv tsawg zog tshaj li ntau lwm txoj kev irrigation nto, xws li furrow irrigation.
Nws kuj muaj cov nqi zog qis dua li cov txheej txheem hauv av uas yuav tsum tau khawb cov kab.
Tsis tas li ntawd, qhov nruab nrab-pivot irrigation tuaj yeem txo cov av tillage.
Nws pab txo cov dej ntws thiab av yaig uas tuaj yeem tshwm sim nrog cov dej hauv av.
Tsawg tillage kuj txhawb ntau cov khoom siv organic thiab cov qoob loo residue kom decompose rov qab rau hauv av.Nws kuj txo cov av compaction.
Qhov nruab nrab pivots feem ntau tsawg dua 500 meters (1,600 ft) ntev (lub vojvoog vojvoog) nrog qhov loj tshaj plaws yog tus qauv 400-meter (1⁄4 mi) tshuab, uas npog txog 50 hectares (125 acres) av.
