Ukulima kuyisayensi njengoba kuyindlela yokuphila.Ukuhlaziya umhlabathi, okungenye yezinto ezibaluleke kakhulu kule sayensi, kunendima ebalulekile okufanele iyidlale.Ake singene siqonde ukuthi kungani kubaluleke kangaka.
Ukubaluleka Kokuhlaziywa Kwenhlabathi Kwezolimo
Ukuhlaziya umhlabathi kuyingxenye ebalulekile yokusebenza kwezolimo, okunomthelela ngqo ekukhuleni kwezitshalo kanye nokukhiqiza.Ngokuqonda ukwakheka komhlabathi, abalimi bangenza izinqumo ezinolwazi ukuze baqinisekise isivuno esiyimpumelelo.
Ukubhekisisa: Kuyini Ukuhlaziywa Kwenhlabathi?
Ukuhlaziywa kwenhlabathi, emnyombweni wawo, ukuhlola amasampula omhlabathi ukuze kutholwe izici zawo ezingokomzimba, amakhemikhali, kanye nezebhayoloji.
Izinhlobo Zokuhlaziya Umhlabathi
Kunezinhlobo ezintathu eziyinhloko zokuhlaziywa kwenhlabathi - amakhemikhali, ngokomzimba, kanye nemvelo.
1. Ukuhlaziywa Kwamakhemikhali
Ukuhlaziywa kwamakhemikhali kuhlola imisoco yenhlabathi kanye namazinga e-pH, okuvumela abalimi ukuthi balungise ukufakwa kukamanyolo ukuze kukhule kahle izitshalo.
2. Ukuhlaziya Umzimba
Ukuhlaziya okubonakalayo kubandakanya ukuhlola ukuthungwa kwenhlabathi kanye nokwakheka, okuthinta ukugcinwa kwamanzi kanye nokungena kwezimpande.
3. Ukuhlaziywa Kwezinto Eziphilayo
Ukuhlaziywa kwebhayoloji kuhlola ama-microorganisms enhlabathini, adlala indima enkulu ekuboleni kwezinto eziphilayo kanye nokujikeleza kwezakhi.
4. Izizathu Eziyinhloko Zokwenziwa Ukuhlaziywa Kwenhlabathi
Ukuqonda izici zomhlabathi kusiza ngezindlela eziningi.
5. Ukulawulwa Kokondleka Kwezitshalo kanye Nomanyolo
Ukuhlaziya umhlabathi uqondisa abalimi ekulawuleni umanyolo kanye nokwenza ngcono ukondliwa kwezitshalo ngokuhlonza ukushoda kwezakhi kanye nokusiza ukuhlanganisa ukufakwa kukamanyolo.
6. Izifo Nokulawula Izinambuzane
Ngokuhlaziya inhlabathi, abalimi bangakwazi ukubona izinto eziphilayo ezibangela izifo emhlabathini, okuvumela izifo ezingcono nokulawulwa kwezinambuzane.
7. Ukuguguleka Komhlaba kanye Nokongiwa
Isiza emizamweni yokongiwa kwenhlabathi ngokusiza abalimi baqonde amandla okuguguleka komhlabathi wabo futhi bathathe izinyathelo zokukunqanda.
Kungani sidinga ukubona inhlabathi yokulima?
Lokhu kungenxa yesidingo sokuhlinzekwa kwezidingo Ukungalingani kanye nokuvundisa okungenangqondo phakathi kwenhlabathi nomanyolo ekukhiqizweni kwezolimo zesimanje.
Kuyadingeka ukuthi umlimi asebenzise umtshina wenhlabathi okala ukunemba kwenhlabathi kanye nokulungisa ukukhiqizwa kwezolimo..
Kungani kukhona ukungalingani phakathi kokuqukethwe kwezakhi zomhlabathi nokuvundisa?
Impendulo isekutheni izilimo ezihlukene zikhipha imisoco ehlukene enhlabathini, ngaleyo ndlela ziqede imisoco ethile yomhlabathi.
Uma kusetshenziswa uhlobo olulodwa kuphela lomanyolo ukuze kugcwaliswe kabusha, akunakwenzeka ukubuyisela ngokuphelele ibhalansi yezakhi zomhlabathi.Ezolimo zesimanje
futhi ibhekana nezinkinga ezifana nokusetshenziswa kukamanyolo ongafanele noma ukusetshenziswa kukamanyolo ngokweqile.Izenzo ezinjalo azigcini nje ngokuholela ekumoshweni
kodwa futhi nomthelela ekungcolisweni kwemvelo futhi okungenzeka, ukwehla kwesivuno sezitshalo.Ukuvundisa ngokweqile kungabangela ukucinana kwenhlabathi
futhi kube nomthelela omkhulu ekusimameni kwethu kwezolimo esikhathini esizayo.
Ngakho singakwazi yini ukushintsha lesi simo?Kumelwe uhlole umhlabathi.Ngoba ingasisiza ukuba sithole imininingwane yenhlabathi.Akukhona kuphela ukutholwa kokuqukethwe kwe-nitrogen, i-phosphorus, i-potassium, izinto eziphilayo, izinga lokushisa lomhlabathi kanye nomswakama, inani le-PH nokunye ukutholwa kwedatha yenkomba nakho kubalulekile.
Ukuqapha izici ezifana nezinga lokushisa lomhlabathi kanye nomswakama kubalulekile empilweni yezitshalo.Uma okuqukethwe kwamanzi enhlabathini kwehla kakhulu, i-photosynthesis - inqubo enika amandla ukukhula kwezitshalo - ingathinteka kabi.Ukuntuleka kwamanzi kakhulu kungaholela ngisho nasekufeni kwezitshalo.
Isamba esiphelele sesikhala esingenalutho senhlabathi sihlala singashintshi, amanzi nomoya kugcwala lesi sikhala.Uma amazinga amanzi ephansi kakhulu, izimpande zezitshalo ziyehluleka ukumunca inani elidingekayo lamanzi.Inqubo yokuphefumula ibangela izitshalo ukuba zilahlekelwe amanzi amaningi, okungase kuholele ekuphelelweni amanzi emzimbeni nasekufeni okulandelayo.Ukuntuleka kwamanzi nakho kungaqinisa inhlabathi futhi kubangele ukuqhekeka, kulimaze isakhiwo nokuvunda kwayo.
Phansiumhlabathi umswakama kanye nomswakamaamazinga angakhinyabeza kakhulu ukukhula okuvamile nokuthuthuka kwezitshalo.Nokho, amanzi amaningi ngokweqile ayingozi ngokufanayo.Uma inhlabathi inamanzi kakhulu, umoya uthatha ingxenye encane yesikhala esingenalutho senhlabathi.Lokhu kuphoqa izimpande zesitshalo ukuthi zishintshele ekuphefumuleni kwe-anaerobic, inqubo ekhiqiza utshwala.Le nto inobuthi ezimpandeni futhi ingabangela ukubola kwezimpande futhi, ezimweni ezimbi kakhulu, ukufa kwezitshalo.
Ukuhlaziywa Kwenhlabathi Kukuthinta Kanjani Ukukhiqiza Kwezolimo
1. Isivuno Esithuthukisiwe Nekhwalithi
Ngokusebenzisa umsoco onembile, ukuhlaziya umhlabathi kungathuthukisa isivuno nekhwalithi yezitshalo.
2. Impilo Yenhlabathi Ethuthukisiwe
Impilo yomhlabathi ibalulekile ekukhiqizeni isikhathi eside kwezolimo.Ukuhlaziya umhlabathi kungakhomba izinkinga futhi kusize abalimi ukuthi bathathe izinyathelo zokuthuthukisa impilo yomhlabathi.
3. Ukulima Okusimeme Nokugcinwa Kwemvelo
Ngokuvumela ukufakwa kukamanyolo okunembayo nokukhuthaza ukongiwa kwenhlabathi, ukuhlaziya umhlabathi kusekela ukulima okusimeme nokongiwa kwemvelo.
4. Ikusasa Lokuhlaziywa Kwenhlabathi Kwezolimo
Njengoba ubuchwepheshe bezolimo buthuthuka, kanjalo nokuhlaziya umhlabathi.Ngokukhula kokunemba kwezolimo kanye nedatha enkulu, ukuhlaziya umhlabathi kuzobe kunembe kakhudlwana
futhi ifinyeleleke, ibe nesandla ekusaseni elisimeme lokulima.
Manje, ngicabanga ukuthi ukuzwisisile ukubaluleka kokuswakama komhlabathi.Mayelana nokukhula kwezitshalo.Hhayi kuphela umswakama.Izinga lokushisa elifanele libalulekile.Izinga lokushisa elifanele lomhlabathi lingcono ekukhuleni kwezitshalo.Amazinga okushisa aphansi kakhulu noma aphezulu kakhulu awakukhuthazi ukukhula kwezitshalo.Imbewu yesitshalo kufanele imiliswe endaweni efanelekile yokushisa kwenhlabathi.Ngaphakathi kwezinga lokushisa elithile, izinga lokushisa lomhlabathi liphezulu, ukukhula kwezitshalo ngokushesha okukhulu.Izitshalo ezehlukene zinezidingo ezihlukene zokushisa.Ukuqapha izinga lokushisa lomhlabathi kwenza izitshalo zikhule ezingeni lokushisa elifanele ukwandisa isivuno.
Ukushisa komswakama womhlabathi kudlala indima ebalulekile ekukhuleni kwezitshalo.Ukuhlola okuvamile kubalulekile.Izinga lokushisa lomhlabathi kanye nenzwa yomswakama iyithuluzi eliphezulu lokuthola izinga lokushisa kanye nomswakama.Iizinga lokushisa kanye nomswakama inzwaisebenzisa izinga lokushisa elihlanganisiwe kanye ne-humidity probe njengento yokulinganisa.Izimpawu zokushisa nomswakama ziqoqwa futhi zicutshungulwe ngokuhlunga kwe-voltage stabilizing, i-amplification yokusebenza, ukulungiswa okungaqondile, ukuguqulwa kwe-V / I, ama-circuits okuvikela amanje kanye ne-reverse.
Okukhiphayo kwesignali yamanje noma ye-voltage iguqulwa ibe ukuhlobana okuqondile kwezinga lokushisa kanye nomswakama.Ukukhishwa kwe-485 noma 232 kuyatholakala futhi nge-chip yokulawula enkulu.Esilinganisweni sokushisa kwenhlabathi kanye nomswakama, i-probe kufanele ifakwe ijule ngangokunokwenzeka enhlabathini, futhi i-probe kufanele igcinwe cishe ngo-1cm kude nenhlabathi ukuze ukukala kube nembe kakhulu.
Izinto eziningi zizosebenzisa ukunemba kokulinganisa, iphenya igobolondofuthi kunethonya elikhulu kumphumela wokuvikela kanye nokungena komoya kwemojula ye-PCB.Izindlu zokuhlunga zensimbi engagqwali zingavikela ukusebenza kahle kwe-PCB.Izindlu zenzwa ye-HENGKO nezinzwa zomswakama zihlala isikhathi eside, zivikela ngokuphepha nangempumelelo amamojula e-PCB emonakalweni, inzuzo enkulu yokuvikela uthuli, i-anti-corrosion futhi ingangeni manzi.Kufika ezingeni lokuvikela le-IP65, imojuli yenzwa yomswakama ingavikelwa ngempumelelo othulini, ukungcola kwezinhlayiyana kanye ne-oxidation yamakhemikhali amaningi, ukuze kuqinisekiswe ukusebenza kwayo okujwayelekile okuzinzile kwesikhathi eside, eduze nempilo yethiyori yenzwa.
Isiphetho
Ukuqonda umhlabathi ngokuwuhlaziya kubalulekile ukuze ukulima kube yimpumelelo.
Njengoba ikusasa lezolimo lihlangana kakhulu nobuchwepheshe, ukuhlaziya umhlabathi kuzoba bucayi kakhulu kunangaphambili.
