Izinkomba eziningi eziqondisweni zokukhula kwezitshalo (PGR) ezisetshenziswa ukotini zibhekisela ku-isopropyl chloride (MC), okuwuphawu lokuhweba olubhaliswe ne-EPA yi-BASF ngo-1980 ngaphansi kwegama lokuhweba elithi Pix.I-Mepiquat nemikhiqizo ehlobene cishe cishe i-PGR esetshenziswa ukotini, futhi ngenxa yomlando wayo omude, i-Pix igama elivamile elishiwo lokuxoxa ngokusetshenziswa kwe-PGR ukotini.
Ukotini ungenye yezitshalo ezibaluleke kakhulu e-United States futhi umkhiqizo omkhulu embonini yemfashini, ukunakekelwa komuntu siqu kanye nobuhle, ukubala ezimbalwa.Uma ukotini usuvuniwe, cishe awukho ukungcola, okwenza ukotini ube yisitshalo esikhangayo nesizuzisa kakhulu.
Ukotini usulinywe iminyaka engaphezu kwezinkulungwane ezinhlanu, futhi kuze kube muva nje, izindlela zokulima zesimanje sezithathe indawo yokukha ngesandla nokulima amahhashi.Imishini eseqophelweni eliphezulu kanye nokunye ukuthuthuka kwezobuchwepheshe (njengokulima okunembayo) kwenza abalimi bakhule futhi bavune ukotini ngendlela ephumelelayo.
I-Mast Farms LLC ipulazi lezizukulwane eziningi eliphethwe wumndeni elitshala ukotini empumalanga ye-Mississippi.Izitshalo zikakotini zivame ukusebenza kahle emhlabathini oyisihlabathi ovundile ojulile, ongenamanzi, ovundile one-pH ephakathi kuka-5.5 no-7.5.Izitshalo eziningi zamarowu e-Mississippi (ukotini, ummbila, nobhontshisi wesoya) zenzeka emhlabathini oyisicaba futhi ojulile we-alluvial ku-delta, okulungele ukulima ngemishini.
Intuthuko yezobuchwepheshe ezinhlotsheni zikakotini ezishintshwe izakhi yenze ukuphathwa nokukhiqizwa kukakotini kwaba lula, futhi lokhu kuthuthuka kuseyisizathu esibalulekile sokwanda okuqhubekayo kwezivuno.Ukushintsha ukukhula kukakotini sekuyingxenye ebalulekile yokukhiqiza ukotini, ngoba uma kulawulwa kahle, kungathinta isivuno.
Okubalulekile ekulawuleni ukukhula ukwazi ukuthi isitshalo sidingani esigabeni ngasinye sokukhula ukuze sifinyelele umgomo wokugcina wesivuno esiphezulu nekhwalithi.Isinyathelo esilandelayo ukwenza konke okusemandleni ukuhlangabezana nalezi zidingo.Izilawuli zokukhula kwezitshalo zingakhuthaza ukuvuthwa kwangaphambi kwesikhathi kwezitshalo, zigcine isikwele kanye ne-boll, zandise ukumuncwa kwezakhi, futhi ziqondise umsoco kanye nokukhula kokuzala, ngaleyo ndlela zandise isivuno kanye nekhwalithi ye-lint.
Inani lezilawuli zokukhula kwezitshalo zokwenziwa ezitholakala kubalimi bakakotini liyakhula.I-Pix iyinto esetshenziswa kakhulu ngenxa yekhono layo lokunciphisa ukumila kukakotini futhi igcizelele ukuthuthukiswa kwe-boll.
Ukuze wazi kahle ukuthi i-Pix ingafakwa nini futhi kuphi ezinkundleni zabo zikakotini, ithimba le-Mast Farms lishayele indiza eyi-AeroVironment Quantix Mapper ukuze liqoqe idatha efike ngesikhathi nenembile.U-Lowell Mullet, Umphathi Wobulungu be-Mast Farms LLC, uthe: “Lokhu kushibhe kakhulu kunokusebenzisa izithombe ezigxilile, kodwa kusivumela ukuthi senze umsebenzi wenziwe ngokushesha okukhulu.
Ngemva kokuthwebula isithombe, ithimba le-Mast Farm lasebenzisa i-Pix4Dfields ukuze lisicubungule ukuze likhiqize imephu ye-NDVI bese lidala imephu yendawo.
ULowell uthe: “Le ndawo ihlanganisa amahektha angama-517.Kusukela ekuqaleni kwendiza kuya lapho ngikwazi ukunikeza isifutho, kuthatha cishe amahora amabili, kuya ngosayizi wamaphikseli ngesikhathi sokucubungula. "“Ngisemhlabeni ongu-517 acres.I-20.4 Gb yedatha yaqoqwa ku-inthanethi, futhi kuthathe cishe imizuzu engama-45 ukucutshungulwa.”
Ezifundweni eziningi, kutholwe ukuthi i-NDVI iyinkomba engaguquki yenkomba yendawo yamaqabunga kanye ne-biomass yezitshalo.Ngakho-ke, i-NDVI noma ezinye izinkomba zingaba ithuluzi elikahle lokuhlukanisa ukukhula kwezitshalo kuyo yonke insimu.
Ngokusebenzisa i-NDVI ekhiqizwe e-Pix4Dfields, ipulazi lensiza lingasebenzisa ithuluzi lokuklama ku-Pix4Dfields ukuhlukanisa izindawo eziphakeme neziphansi zezitshalo.Ithuluzi lihlukanisa insimu ibe amazinga ohlaza amathathu ahlukene.Skrina indawo yendawo ukuze unqume ukuphakama kwe-node ratio (HNR).Lesi yisinyathelo esibalulekile ekunqumeni izinga le-PGR elisetshenziswa endaweni ngayinye.
Ekugcineni, sebenzisa ithuluzi lokuhlukanisa ukuze udale incwadi kadokotela.Ngokusho kwe-HNR, isilinganiso sabelwe indawo ngayinye enezitshalo.I-Hagie STS 16 ifakwe i-Raven Sidekick, ngakho i-Pix ingajovwa ngokuqondile ku-boom ngesikhathi sokufafaza.Ngakho-ke, amanani esistimu yomjovo anikezwe indawo ngayinye angu-8, 12, kanye no-16 oz/acre ngokulandelanayo.Ukuze uqedele incwadi kadokotela, thekelisa ifayela bese ulilayisha emshinini wokufafaza ukuze ulisebenzise.
I-Mast Farms isebenzisa izifutho ze-Quantix Mapper, i-Pix4Dfields kanye ne-STS 16 ukuze kufakwe i-Pix ngokushesha nangempumelelo ezinsimini zikakotini.
