Ofufuza a Clemson amapatsa alimi chida chatsopano chothana ndi udzu wokwera mtengo

Malangizowo amachokera kwa Matt Cutull, pulofesa wothandizira wa sayansi ya udzu ku Clemson Coastal Research and Education Center.Cutulle ndi ofufuza ena a zaulimi adapereka njira za "kusamalira udzu wophatikizika" pamsonkhano waposachedwa ku Clemson Madron Convention Center ndi Student Organic Farm.
Udzu umapikisana ndi mbewu pazakudya zam'nthaka, zomwe zimapangitsa $32 biliyoni pakuwonongeka kwa mbewu pachaka, adatero Cutulle.Kusamalira bwino udzu kumayamba pamene alimi awona nthawi yopanda udzu, nthawi yovuta kwambiri m'nyengo ya kukula pamene namsongole amawononga kwambiri mbewu, akutero.
"Nthawiyi imatha kusiyana kwambiri malinga ndi mbewu, momwe imakulira (mbewu kapena kuziika), komanso mitundu ya namsongole yomwe ilipo," adatero Cutulle."Nthawi yofunika kwambiri yopanda udzu ikhala milungu isanu ndi umodzi, koma izi zithanso kusiyanasiyana kutengera mbewu ndi udzu womwe ulipo."
Nthawi Yopanda Udzu Waudzu ndi nthawi yolima pamene kusunga mbewu mopanda udzu ndikofunikira kuti alimi azitha kukolola kwambiri.Pambuyo pa nthawi yovutayi, alimi ayenera kuyang'ana kwambiri kupewa kubzala udzu.Alimi angachite zimenezi posiya njerezo kuti zimere kenako n’kuzipha, kapenanso zingalepheretse kumera n’kudikirira kuti mbewuzo zife kapena kudyedwa ndi nyama zodya mbewu.
Njira imodzi ndiyo kutenthetsa kwa dzuwa, komwe kumaphatikizapo kugwiritsa ntchito kutentha kwadzuwa pofuna kuwononga tizilombo towononga nthaka.Izi zimatheka pophimba nthaka ndi phula la pulasitiki looneka bwino m’nyengo yotentha pamene nthaka idzakhala padzuwa kwa milungu isanu ndi umodzi.The pulasitiki tarp kutentha pamwamba wosanjikiza dothi 12 mpaka 18 mainchesi wokhuthala ndi kupha tizirombo zosiyanasiyana kuphatikizapo udzu, zomera tizilombo toyambitsa matenda, nematodes ndi tizilombo.
Kutsekemera kwa nthaka kungathandizenso kuti nthaka ikhale ndi thanzi labwino mwa kufulumizitsa kuwonongeka kwa zinthu zachilengedwe ndikuwonjezera kupezeka kwa nayitrogeni ndi zakudya zina ku zomera zomwe zikukula, komanso kusintha mopindulitsa madera a nthaka (mabakiteriya ndi bowa omwe amakhudza thanzi la nthaka ndipo pamapeto pake pa thanzi la zomera) .
Anaerobic nthaka disinsection ndi sanali mankhwala m'malo ntchito fumigants ndipo angagwiritsidwe ntchito kulamulira osiyanasiyana tizilombo tochokera nthaka ndi nematodes.Izi ndi njira zitatu zomwe zimaphatikizapo kuwonjezera gwero la carbon kunthaka lomwe limapereka zakudya ku tizilombo topindulitsa ta nthaka.Nthaka imathiriridwa mpaka kuthirira ndikukutidwa ndi mulch wa pulasitiki kwa milungu ingapo.Pothira mphutsi, mpweya wa m’nthaka umachepa ndipo zinthu zapoizoni zimapha tizilombo toyambitsa matenda tochokera m’nthaka.
Kugwiritsa ntchito mbewu zovundikira kumayambiriro kwa nyengo kuletsa udzu kungakhale kothandiza, koma kupha ndikofunikira, akutero Jeff Zender, wotsogolera pulogalamu ya Clemson yaulimi wokhazikika.
“Alimi amasamba nthawi zambiri samabzala mbewu zotchinga chifukwa cha kasamalidwe kabwino, kuphatikizapo nthawi yabwino yobzala mbewu zotchingira m’munda kuti zimera bwino,” adatero Zender.“Ukapanda kubzala pa nthawi yoyenera, ukhoza kukhala wopanda mafuta okwanira, ndiye ukaugudubuza, sungathe kupondereza udzu.Nthawi ndiyofunika kwambiri. "
Mbewu zophimba bwino kwambiri ndi kapezi clover, dzinja rye, dzinja balere, masika balere, masika oats, buckwheat, mapira, hemp, black oats, vetch, nandolo ndi dzinja tirigu.
Pali maudzu ambiri oletsa udzu pamsika masiku ano.Kuti mumve zambiri za kuletsa udzu pobzala ndi kumiza, onani Clemson Home and Garden Information Center 1253 ndi/kapena HGIC 1604.
Cutulle ndi ena ku Clemson Coastal REC, pamodzi ndi ofufuza a Clemson's student organic farm, akuyang'ana njira zina zowononga udzu, kuphatikizapo kugwiritsa ntchito nayitrogeni wamadzimadzi kuti aziundana namsongole asanawaphe ndi kugubuduza mbewu zophimba ndi chogudubuza.Anakonza otsika kutentha udzu.
"Alimi ayenera kumvetsetsa udzu - chizindikiritso, biology, ndi zina zotero - kuti athe kusamalira minda yawo ndikupewa mavuto a udzu m'mbewu zawo," adatero.
Alimi ndi wamaluwa amatha kuzindikira udzu pogwiritsa ntchito tsamba la Clemson Weed ID ndi Biology lopangidwa ndi wothandizira labu la Coastal REC Marcellus Washington.
