Maumboni ambiri okhudza kukula kwa mbewu (PGR) omwe amagwiritsidwa ntchito mu thonje amatchula isopropyl chloride (MC), chomwe ndi chizindikiro cholembetsedwa ndi EPA ndi BASF mu 1980 pansi pa dzina la malonda Pix.Mepiquat ndi zinthu zina zofananira ndizo pafupifupi PGR yomwe imagwiritsidwa ntchito mu thonje, ndipo chifukwa cha mbiri yakale, Pix ndi nthawi yotchulidwa pokambirana za kugwiritsa ntchito PGR mu thonje.
Thonje ndi imodzi mwa mbewu zofunika kwambiri ku United States ndipo ndi chinthu chachikulu m'makampani opanga mafashoni, chisamaliro chamunthu komanso kukongola, kungotchulapo zochepa.thonje likakololedwa, sipakhala zotayika, zomwe zimapangitsa thonje kukhala mbewu yokongola komanso yopindulitsa.
Thonje wakhala akulimidwa kwa zaka zoposa 5,000, ndipo mpaka posachedwapa, njira zaulimi zamakono zalowa m’malo mwa kuthyola ndi kulima akavalo.Makina apamwamba komanso kupita patsogolo kwaukadaulo (monga ulimi wolondola) kumathandiza alimi kulima ndi kukolola thonje bwino.
Mast Farms LLC ndi famu ya mabanja yamibadwo yambiri yomwe imalima thonje kummawa kwa Mississippi.Zomera za thonje zimakonda kuchita bwino mu dothi lakuya, lotayidwa bwino, lachonde lamchenga lokhala ndi pH pakati pa 5.5 ndi 7.5.Mbewu zambiri zam'mizere ku Mississippi (thonje, chimanga, ndi soya) zimachitika mu dothi lathyathyathya komanso lozama kwambiri mu delta, zomwe zimathandizira ulimi wamakina.
Kupita patsogolo kwaukadaulo mumitundu ya thonje yosinthidwa ma genetic kwapangitsa kuti kasamalidwe ka thonje kakhale kosavuta, ndipo kupita patsogoloku ndikadali chifukwa chofunikira chakuchulukirachulukira kwa zokolola.Kusintha kukula kwa thonje kwakhala chinthu chofunika kwambiri pakupanga thonje, chifukwa ngati kuyendetsedwa bwino, kungakhudze zokolola.
Chofunikira pakuwongolera kukula ndikudziwa zomwe mbewu imafunikira pagawo lililonse lachitukuko kuti ikwaniritse cholinga chachikulu cha zokolola zapamwamba komanso zabwino.Chotsatira ndikuchita zonse zotheka kukwaniritsa zosowazi.Zowongolera zakukula kwa mbewu zimatha kulimbikitsa kukhwima kwa mbewu, kukhala ndi masikweya awiri, kukulitsa kuyamwa kwa michere, ndikuwongolera kadyedwe ndi kakulidwe ka uchembere, potero kumawonjezera zokolola ndi mtundu wa lint.
Chiwerengero cha zowongolera zopangira kukula kwa mbewu zomwe amalima thonje zikuchulukirachulukira.Pix ndiye chinthu chomwe chimagwiritsidwa ntchito kwambiri chifukwa chotha kuchepetsa kukula kwa thonje ndikugogomezera kukula kwa boll.
Pofuna kudziwa nthawi komanso malo omwe angagwiritsire ntchito Pix ku minda yawo ya thonje, gulu la Mast Farms linayendetsa ndege ya AeroVironment Quantix Mapper kuti itengere nthawi yake komanso yolondola.Lowell Mullet, Woyang'anira Umembala wa Mast Farms LLC, adati: "Izi ndizotsika mtengo kuposa kugwiritsa ntchito zithunzi zamapiko osasunthika, koma zimatilola kuti ntchitoyi ichitike mwachangu kwambiri.
Atajambula chithunzichi, gulu la Mast Farm linagwiritsa ntchito Pix4Dfields kuti lizikonza kuti lipange mapu a NDVI ndikupanga mapu a zone.
Lowell anati: “Derali lili ndi maekala 517.Kuyambira pachiyambi cha ndege mpaka pamene ndingathe kulembera mu sprayer, zimatenga pafupifupi maola awiri, kutengera kukula kwa ma pixel panthawi yokonza. ""Ndili pamtunda wa maekala 517.20.4 Gb ya data idasonkhanitsidwa pa intaneti, ndipo zidatenga pafupifupi mphindi 45 kuti zitheke. "
M'maphunziro ambiri, zapezeka kuti NDVI ndi chizindikiro chokhazikika cha tsamba lamasamba ndi biomass ya mbewu.Chifukwa chake, NDVI kapena ma indices ena atha kukhala chida choyenera kugawira kusiyana kwa kukula kwa mbewu m'munda wonse.
Pogwiritsa ntchito NDVI yopangidwa ku Pix4Dfields, famu ya mast ingagwiritse ntchito chida choyang'anira malo ku Pix4Dfields kuyika madera apamwamba ndi apansi a zomera.Chidacho chimagawanitsa mundawo m'magawo atatu a zomera.Yang'anani dera laderalo kuti mudziwe kutalika kwa chiŵerengero cha node (HNR).Ili ndi gawo lofunikira pakuzindikira kuchuluka kwa PGR komwe kumagwiritsidwa ntchito m'dera lililonse.
Pomaliza, gwiritsani ntchito chida chogawa kuti mupange mankhwala.Malinga ndi HNR, mtengowo umaperekedwa kudera lililonse la zomera.Hagie STS 16 ili ndi Raven Sidekick, kotero Pix imatha kubayidwa mwachindunji mu boom popopera mbewu mankhwalawa.Chifukwa chake, mitengo ya jakisoni yoperekedwa kugawo lililonse ndi 8, 12, ndi 16 oz/ekala motsatana.Kuti mumalize kulemba, tumizani fayiloyo ndikuyiyika mu makina opopera kuti mugwiritse ntchito.
Mast Farms amagwiritsa ntchito makina opopera a Quantix Mapper, Pix4Dfields ndi STS 16 kuti agwiritse ntchito Pix m'minda ya thonje mwachangu komanso moyenera.
