Uguquko "olunomdla" kwizolimo ezichanekileyo: Indlela izinzwa ze-pH zamanzi ezikhuthaza ngayo ukulima kwanamhlanje

Isishwankathelo: Kwixesha lotshintsho oluvela kwezolimo zemveli ukuya kwezolimo ezichanekileyo nezikrelekrele, izinzwa ze-pH zomgangatho wamanzi ziyaguquka zisuka kwizixhobo zelebhu ezingaziwayo ziye kwi "iingcongconi zokungcamla ezikrelekrele" zentsimi. Ngokujonga i-pH yamanzi okunkcenkceshela ngexesha langempela, zikhusela ukukhula kwesityalo kwaye zibe yinxalenye ebalulekileyo kulawulo lwamanzi kunye nezichumiso zesayensi.

I. Imvelaphi yetyala: Ingxaki ye "Tomato Valley"

Kwisiseko semiboniso yezolimo sanamhlanje se-"Green Source" eMpuma China, kwakukho i-greenhouse yeglasi yanamhlanje engama-500 eehektare eyayijolise ekukhuliseni iitumato zecherry ezikumgangatho ophezulu, ezaziwa ngokuba yi-"Tomato Valley." Umphathi wefama, uMnu. Wang, wayehlala ekhathazwa yingxaki: ukukhula kwezityalo okungalinganiyo, kunye nokutyheli kwamagqabi kunye nokukhula okuncinci kwezinye iindawo, kunye nokusebenza kakuhle kwesichumiso.

Emva kophando lokuqala, izinambuzane, izifo, kunye nokunqongophala kwezondlo kwasuswa. Ekugqibeleni ingqwalasela yatshintshela emanzini okunkcenkceshela. Umthombo wamanzi wawuvela kumlambo okufutshane waza waqokelela amanzi emvula, kwaye ixabiso le-pH yawo latshintsha ngenxa yotshintsho lwemozulu kunye nokusingqongileyo. Bacinga ukuba i-pH yamanzi engaguqukiyo yayichaphazela ukufumaneka kwesichumiso, nto leyo eyakhokelela kwiingxaki ezibonwe.

II. Isisombululo: Ukusebenzisa Inkqubo yokubeka iliso kwi-pH ekrelekrele

Ukusombulula le ngxaki ngokuqinisekileyo, isiseko se-"Green Source" sazisa saza sasebenzisa inkqubo yokujonga amanzi okunkcenkceshela ekrelekrele esekelwe kwiisensa ze-pH zomgangatho wamanzi ezikwi-intanethi.

1. Ukwakhiwa kwenkqubo:
   • IiSensors ze-pH ezikwi-Intanethi: Zifakwe ngqo kumbhobho ophambili wokungenisa amanzi okunkcenkceshela nakwindawo yokuphuma kwitanki yokuxuba isichumiso kwigreenhouse nganye. Ezi sensors zisebenza ngokomgaqo wendlela ye-electrode, zivumela ukufunyanwa kwe-pH yamanzi rhoqo, ngexesha langempela.
   • Imodyuli yokuFumana idatha kunye nokuThunyelwa kwayo: Iguqula imiqondiso ye-analog evela kwiisensa ibe yimiqondiso yedijithali kwaye izithumele ngaphandle kwentambo kwiqonga lolawulo eliphakathi ngetekhnoloji ye-Intanethi yezinto (IoT).
   • Iqonga loLawulo oluPhakathi oluhlakaniphileyo: Inkqubo yesoftware esekwe kwilifu enoxanduva lokufumana, ukugcina, ukubonisa, nokuhlalutya idatha ye-pH, kunye nokuseta imida yolawulo.
   • Inkqubo Yokulungisa Ngokuzenzekelayo (Ukhetho): Iqhagamshelwe kwiqonga, ilawula ngokuzenzekelayo ukufakwa kwesisombululo se-asidi encinci (umz., i-phosphoric acid) okanye i-alkali (umz., i-potassium hydroxide) ukuze ilungise ngokuchanekileyo i-pH xa amaxabiso edlula kuluhlu.
2. Ukuhamba komsebenzi:
   • Ukubeka esweni ngexesha langempela: I-pH yamanzi okunkcenkceshela ibanjwa ngexesha langempela ziisensors ngaphambi kokuba ingene kwinkqubo yokunkcenkceshela ngokuthontsiza.
   • Ii-Threshold Alarms: Uluhlu lwe-pH olufanelekileyo lokukhula kwetamatisi yecherry (5.5-6.5) lubekwe kwiqonga lolawulo eliphakathi. Ukuba i-pH yehla ngaphantsi kwe-5.5 okanye inyuka ngaphezulu kwe-6.5, inkqubo ithumela isilumkiso kubaphathi nge-app yeselula okanye ikhompyutha ngoko nangoko.
   • Uhlalutyo lweDatha: Eli qonga livelisa iitshathi zeendlela ze-pH, linceda abaphathi ukuba bahlalutye iipatheni kunye nezizathu zokuguquguquka kwe-pH.
   • Uhlengahlengiso Oluzenzekelayo/olwenziwa ngesandla: Inkqubo ingasetwa kwimo ezenzekelayo ngokupheleleyo, yongeza i-asidi okanye i-alkali ukuze ilungelelanise ngokuchanekileyo i-pH kwixabiso ekujoliswe kulo (umz., 6.0). Okanye, abaphathi banokuyivula ngesandla inkqubo yohlengahlengiso bekude xa befumana isilumkiso.

III. Iziphumo zesicelo kunye nexabiso

Emva kweenyanga ezintathu zokusebenzisa le nkqubo, isiseko se-"Green Source" sifumene iingenelo ezibalulekileyo kwezoqoqosho nakwindalo:

1. Ukuphucula Ukusebenza Komgquba, Iindleko Ezincitshisiweyo:
   • Uninzi lwezondlo (ezifana nenitrogen, iphosphorus, ipotassium) zifumaneka lula kwizityalo ezikwindawo eneasidi encinci (pH 5.5-6.5). Ngokulawula ngokuchanekileyo i-pH, ukusebenza kakuhle kokusetyenziswa kwezichumisi kwanda malunga ne-15%, kunciphisa ukusetyenziswa kwezichumisi malunga ne-10% ngelixa kugcinwa isivuno.
2. Impilo yeZityalo ePhucukileyo, Umgangatho oPhucukileyo kunye neSivuno:
   • Ingxaki ezinje "nge-chlorosis yokungabikho kwezondlo" (amagqabi atyheli), eziye zenzeka ngenxa yokuba i-pH ephezulu yavala izondlo ezincinci ezifana ne-iron kunye ne-manganese, nto leyo eyenza ukuba zingafumaneki kwizityalo. Ukukhula kwezityalo kwafana, kwaye amagqabi ajika aba luhlaza olusempilweni.
   • Inqanaba leBrix, incasa, kunye nokungaguquguquki kweetumato zecherry kuphucuke kakhulu. Izinga leziqhamo ezithengiswayo linyuke nge-8%, nto leyo ephucula ngokuthe ngqo imbuyekezo yezoqoqosho.
3. Ulawulo Oluchanekileyo Olusebenzayo, Abasebenzi Abasindisiweyo:
   • Ndatshintsha indlela endala yokufuna iisampulu rhoqo ngesandla kunye novavanyo ngemigca yovavanyo lwe-pH okanye iimitha eziphathwayo. Ndasebenzisa ukubekwa esweni okungajongwanga iiyure ezingama-24/7, ndasindisa kakhulu abasebenzi kwaye ndasusa iimpazamo zabantu.
   • Abaphathi banokujonga imeko yomgangatho wamanzi kuyo yonke inkqubo yokunkcenkceshela nangaliphi na ixesha, naphi na ngeefowuni zabo, nto leyo ephucula kakhulu ukusebenza kakuhle kolawulo.
4. Ukuvaleka kweNkqubo okuThintelweyo, Iindleko zoLondolozo eziNciphisiweyo:
   • I-pH ephezulu kakhulu inokubangela ukuba i-calcium kunye ne-magnesium ions emanzini zinyuke, zenze isikali esivala ii-emitters ezithambileyo. Ukugcina i-pH efanelekileyo kunciphise ukwakheka kwesikali, kwandisa ubomi benkqubo yokunkcenkceshela nge-drip, kwaye kunciphisa amaxesha okugcinwa kunye neendleko.

IV. Imbono yexesha elizayo

Ukusetyenziswa kwezinzwa ze-pH zamanzi kudlulela ngaphaya koku. Kwisicwangciso sezolimo ezikrelekrele zexesha elizayo, kuya kudlala indima ebaluleke ngakumbi:

• Ukuhlanganiswa Okunzulu Neenkqubo Zokuchumisa: Iisensa ze-pH ziya kudibana neesensa ze-EC (Electrical Conductivity) kunye nee-electrodes ezahlukeneyo ezikhetha i-ion (umz., kwi-nitrate, i-potassium) ukwenza "inkqubo epheleleyo yokuxilonga izondlo" yokuchumisa okufunekayo kunye nokunkcenkceshela ngokuchanekileyo.
• Ulawulo Lokuqikelela Olusebenzisa I-AI: Ngokuhlalutya idatha ye-pH yembali, idatha yemozulu, kunye neemodeli zokukhula kwezityalo ezine-algorithms ze-AI, inkqubo inokuqikelela iindlela ze-pH kwaye ingenelele ngokubonakalayo, isuka "kulawulo lwexesha langempela" iye "kulawulo lokuqikelela."
• Ukwandiswa kwezeNdalo zasemanzini kunye nokuJongwa koMhlaba: Le ndlela ifanayo ingasetyenziswa ukulawula umgangatho wamanzi kumachibi eefama kwaye isetyenziswe njengezixhobo zokujonga i-pH yomhlaba ngaphakathi, ukudala inethiwekhi ebanzi yokujonga okusingqongileyo kwezolimo.

Isiphelo:

Ityala lesiseko se-"Green Source" libonisa ngokucacileyo ukuba i-sensor ye-pH yamanzi ethobekileyo yibhulorho edibanisa ulawulo lwemithombo yamanzi kunye nempilo yesondlo sezityalo. Ngokubonelela ngedatha eqhubekayo nechanekileyo, iqhubela phambili "ezolimo ezisekelwe kumava" zendabuko "kwizolimo ezikrelekrele eziqhutywa yidatha," inika inkxaso eqinileyo yobugcisa yokufezekisa ulondolozo lwamanzi, ukunciphisa izichumiso, ukuphucula umgangatho, ukuphucula ukusebenza kakuhle, kunye nophuhliso lwezolimo oluzinzileyo.
