Uninzi lweereferensi kubalawuli bokukhula kwezityalo (PGR) ezisetyenziswa kwikotoni zibhekisa kwi-isopropyl chloride (MC), uphawu lokuthengisa olubhaliswe ne-EPA yi-BASF kwi-1980 phantsi kwegama lezorhwebo le-Pix.I-Mepiquat kunye neemveliso ezihambelanayo ziphantse zaphela i-PGR esetyenziswa kumqhaphu, kwaye ngenxa yembali yayo ende, i-Pix ligama elikhankanyiweyo eliqhelekileyo lokuxoxa ngokusetyenziswa kwe-PGR kumqhaphu.
Umqhaphu sesinye sezona zityalo zibalulekileyo e-United States kunye nemveliso enkulu kwifashoni, ukhathalelo lomntu kunye namashishini obuhle, ukukhankanya ezimbalwa.Wakuba uvuniwe umqhaphu, akubikho nkcitho, nto leyo eyenza umqhaphu ube sisityalo esinomtsalane nesiluncedo.
Umqhaphu ubulinywa iminyaka engaphezu kwamawaka amahlanu, yaye kude kube kutshanje, iindlela zokulima zale mihla zithabathel’ indawo ukuvunwa ngesandla nokufuya amahashe.Oomatshini abakwizinga eliphezulu kunye nolunye uphuculo lwezobuchwepheshe (ezifana nezolimo ezichanekileyo) zenza abalimi bakhule kwaye bavune umqhaphu ngokufanelekileyo.
Iifama zeMast LLC yifama yosapho enezizukulwana ezininzi ekhulisa umqhaphu empuma yeMississippi.Izityalo zomqhaphu zikholisa ukusebenza kakuhle kumhlaba ovunduvundu obunzulu, otsalwe kakuhle, nochumileyo onesanti evundileyo ene pH ephakathi kwe 5.5 kunye ne 7.5.Uninzi lwezityalo ezikroliweyo e-Mississippi (umqhaphu, umbona, kunye neembotyi zesoya) zenzeka kumhlaba othe tyaba kunye nonzulu we-alluvial kwi-delta, ekhuthaza ulimo olusetyenziswa ngoomatshini.
Ukuqhubela phambili kwezobugcisa kwiintlobo zekotoni eziguqulwe ngokwemfuza zenze ukuba ulawulo lwekotoni kunye nokuveliswa lula lula, kwaye ezi nkqubela zisesona sizathu esibalulekileyo sokunyuka okuqhubekayo kwezivuno.Ukutshintsha ukukhula kwekotoni kuye kwaba yinxalenye ebalulekileyo yemveliso yekotoni, kuba xa ilawulwa ngokufanelekileyo, inokuchaphazela isivuno.
Isitshixo sokulawula ukukhula kukwazi ukuba isityalo sidinga ntoni kwinqanaba ngalinye lophuhliso ukuze sifezekise eyona njongo yesivuno esiphezulu kunye nomgangatho.Inyathelo elilandelayo kukwenza konke okusemandleni ukuhlangabezana nezi mfuno.Izilawuli zokukhula kwezityalo zinokukhuthaza ukukhula kwangoko kwezityalo, zigcine isikwere kunye ne-boll, ukwandisa ukufunxa izondlo, kwaye zilungelelanise isondlo kunye nokukhula kokuzala, ngokwandisa isivuno kunye nomgangatho we-lint.
Inani lezixhobo zokulawula ukukhula kwezityalo zokwenziwa ezifumanekayo kubalimi bomqhaphu liyakhula.I-Pix yeyona nto isetyenziswa kakhulu ngenxa yokukwazi ukunciphisa ukukhula komqhaphu kwaye kugxininise uphuhliso lwe-boll.
Ukuze ukwazi kakuhle ukuba nini kwaye kuphi ukufaka i-Pix kwiindawo zabo zekotoni, iqela leeFama zeMast liqhube i-AeroVironment Quantix Mapper drone ukuqokelela idatha ngexesha elifanelekileyo kunye nechanekileyo.ULowell Mullet, uMphathi woBulungu beMast Farms LLC, uthe: “Oku kunexabiso eliphantsi kunokusebenzisa imifanekiso enamaphiko, kodwa kuyasivumela ukuba wenziwe umsebenzi ngeyona ndlela ikhawulezayo.
Emva kokuthatha umfanekiso, iqela leFama yeMast lisebenzise i-Pix4Dfields ukuyiqhuba ukuze ivelise imephu ye-NDVI emva koko lenze imephu yendawo.
ULowell wathi: “Lo mmandla ugubungela iihektare ezingama-517.Ukusukela ekuqaleni kwenqwelomoya ukuya xa ndikwazi ukumisela kwisitshizi, kuthatha malunga neeyure ezimbini, kuxhomekeke kubungakanani beepikseli ngexesha lokusetyenzwa. ”“Ndikumhlaba oziihektare ezingama-517.I-20.4 Gb yedatha yaqokelelwa kwi-Intanethi, kwaye kuthathe malunga nemizuzu engama-45 ukuqhubekeka.
Kuphononongo oluninzi, kufunyaniswe ukuba i-NDVI sisalathiso esingaguqukiyo sesalathiso sendawo yegqabi kunye ne-biomass yezityalo.Ke ngoko, i-NDVI okanye ezinye ii-indices zinokuba sisixhobo esifanelekileyo sokwahlula ukuhluma kwezityalo kwintsimi yonke.
Ukusebenzisa i-NDVI eveliswe kwii-Pix4Dfields, ifama yemast inokusebenzisa isixhobo socando kwi-Pix4Dfields ukuhlela iindawo eziphezulu nezisezantsi zezityalo.Isixhobo sahlula intsimi ibe ngamanqanaba amathathu ohlaza ahlukeneyo.Khupha indawo yendawo ukujonga ubude ukuya kumlinganiselo we-node (HNR).Eli linyathelo elibalulekileyo ekumiseleni izinga lePGR elisetyenziswa kwindawo nganye.
Ekugqibeleni, sebenzisa isixhobo sokwahlula ukwenza umyalelo.Ngokwe-HNR, umlinganiselo wabelwe indawo nganye yezityalo.IHagie STS 16 ixhotyiswe ngeRaven Sidekick, ngoko ke iPix inokutofwa ngokuthe ngqo kwi-boom ngexesha lokutshiza.Ke ngoko, amaxabiso enkqubo yokutofa anikezelwe kwindawo nganye yi-8, 12, kunye ne-16 oz/acre ngokulandelelanayo.Ukugqiba umyalelo, thumela ngaphandle ifayile kwaye uyilayishe kwisitshizi esweni ukuze isetyenziswe.
Iifama zeMast zisebenzisa iQuantix Mapper, iPix4Dfields kunye nezitshizi ze-STS 16 ukuze zifake ngokukhawuleza nangempumelelo iPix kumasimi ekotoni.
