Kuyini ngenkasa? izinhlobo ngenkasa

Kuyini ngenkasa? Lona omunye ubuchwepheshe ezibaluleke kakhulu asetshenziswa kwezolimo. Zonke izitshalo zidinga amanzi adingekayo-photosynthesis, ngazo ukukhiqiza udaba eziphilayo sikhule, ukuthuthukisa futhi ekugcineni izithelo. Ngaphandle amanzi anikeza ukuphila ngeke kube khona isidalwa esiphilayo olulodwa emhlabeni.

Kuyini ngenkasa?

Yonke-ecosystem, kuhlanganise nezilwane, izitshalo, futhi abantu ngeke esasizobhujiswa uma ongawamukeli nesilinganiso esifanele samanzi. Yingakho abalimi bathintwa ngaso sonke isikhathi kusetshenziswe inqubo ukuthambisa yokufakelwa. Kuyini ngenkasa? Lona wokwethula amanzi anikeza ukuphila izitshalo ezikhulayo. Le ndlela kubalulekile ikakhulukazi lapho kukhona imvula kancane.

Izinhlobo ngenkasa izinhlelo

Kunezinhlobo eziningi uchelela, ezisetshenziswa abalimi, kuye ngokuthi isivuno ezikhulayo imvelo. Izindlela ezivame kakhulu yilezi:

1. Okusobala ukuthambisa, esebenzisa amandla adonsela phansi ukusabalalisa amanzi zinqamule insimu. notshwala Water kusukela endaweni ephakeme phansi ukuze uthole wonke amasiko. Uma lezi emithambekeni zidalwe ngemishini, bese le ndlela kuyinto kunalokho isikhathi. Isibonelo Classic of ukuchelela phezu kwenhlabathi kukhona inkambu erayisi eMpumalanga Asia.

2. ngenkasa yenziwe yaba yasendaweni wenziwa esebenzisa uhlelo ipayipi ukuze amanzi afakwe uzungeze inkundla. Leli fomu lihlanganisa drip irrigation eyenzeka enikezela umswakama izimpande isitshalo ngqo. Subsurface ngenkasa siqukethe izindlela amanzi ngenkasa basakaza ngaphansi kwamanzi emhlabathini. Uyini ngenkasa ukuvuza? Lolu hlobo luyehluka kuye ngokuthi komhlaba ukujula. Lapho izinga labo kakhulu ngaphansi kwamanzi, apharathasi ejection angaluboni ngaphansi kwamanzi kwenhlabathi, ngokuvamile indawo impande izitshalo.

3. Siyini ngenkasa emasimini ukufafaza ekhanda? Lolu hlobo ezifanayo kuya yokufafaza inisele utshani. Irrigation ipayipi wuhlelo Umfutho amanzi ukuhlakazwa ezilimweni. Ukuhluka zalesi simiso ingafaka rotary ethela, zinqunywa umbuthano.

4. Lo simende central - kungolunye uhlobo ngenkasa, esebenzisa isifutho kungenziwa rotated, ukushintsha isiqondiso sayo. Yokufafaza ogibele amathrekhi mechanical ukuthi ukuhambisa kubo nxazonke ngakho wenza amanzi spray iyunifomu ezilimweni.

Ukusetshenziswa ngenkasa izinhlelo

Uyini ukunisela amasimu ukuthi isetshenziselwa? Le ndlela uchelela, esebenzisa eziklanyelwe uhlelo amanzi ngqo izitshalo. Le ndlela isetshenziswa ukusiza zikhula izitshalo kanye nokugcinwa lobuchwepheshe ebukeka. Ukusetshenziswa ngenkasa izinhlelo kusiza ukuvikela izitshalo kusuka frost, sivimbela ukukhula ukhula wokudla emasimini iphinde ivimbele inhlabathi ukuhlanganisa. Ngokomlando, ukuthi ngenkasa yikona okwaba mhlobiso wezolimo iminyaka engaphezu 5000 iminyaka futhi kuyinto indlela evame ukunakekelwa isitshalo emiphakathini eminingi namanje.

Amanzi - ama-Irreplaceable loyimvelo

Umqondo eziyisisekelo kusetshenziswa isimiso sokunisela ngenkasa yokufakelwa ukuthi izitshalo fed okunengqondo enele umthamo wamanzi. Ukuze kulondolozwe lolu ezibalulekile loyimvelo isidingo ukusebenzisa lezo zindlela ukuze usize unciphise ukulahlekelwa yayo futhi ngeke umsindise isikhathi, imali, ekuvimbeleni ukukhula ukhula nokukhuphula izinga ukukhula kwezitshalo, izitshalo kanye nezimbali. Ukunisela izitshalo kubalulekile kuwo wonke umhlaba, njengoba inhloso yayo emhlabeni wonke ukunikeza kwenani labantu emhlabeni njalo agcwaliswa amasheya ukudla.

izimo zemvelo njengesici esibangela i-nokufaneleka yezindlela ezihlukahlukene ngenkasa

Lezi zihlanganisa uhlobo umhlabathi, khona nemithambeka, isimo sezulu, izinga lamanzi nokutholakala. Ngokwesibonelo, nenhlabathi sandy abe umswakama okuqukethwe ongaphakeme kanye eliphezulu filtration isilinganiso. Ngakho-ke, kudingeka njalo kodwa ezincane ngenkasa ukungenelela. On loam noma ubumba nenhlabathi nge ongaphakeme Ukungena ezingeni ingasetshenziswa zonke izindlela eyaziwa uchelela, ezivame ukusetshenziswa ukuchelela phezu kwenhlabathi. Irrigation kanye ngenkasa ukuvuza luncanyelwa emazweni ezitshekile, ngoba isicelo sabo kudinga ebusweni cishe ngokuphelele flat. Wenza okuhlukile is irayisi wanda ngezinga masimu ezitshekile amazwe. Umoya kungaphazamisa sishaye amanzi Sprinkler. Ngo ezinomoya kakhulu izindlela drip irrigation eyenzeka kanye ebusweni ezwakala. Ukusentshenziswa kwamanzi kahle liphakeme ngoba ukufafaza kanye drip irrigation eyenzeka, kunokuba babe ukuthambisa ebusweni, ngoba lezi izindlela ayethanda lapho amanzi buyivelakancane.

Kuye uhlobo isiko

Ngaphandle kweqiniso lokuthi wokunisela anjalo, kufanele kuphawulwe ukuthi isici esibalulekile nokufaneleka uhlelo kuncike uhlobo kwezitshalo. Ngokwesibonelo, ukuchelela phezu kwenhlabathi ingase isetshenziselwe zonke izinhlobo zezilimo. Ngenxa okusezingeni eliphezulu ukutshalwa kwezimali ngayinye ehektheleni ukuvuza Sprinkler futhi ikakhulukazi esetshenziselwa ezibizayo lezimpahla izitshalo ezifana imifino nemithi yezithelo. Drip irrigation eyenzeka ilungele ukuchelela izitshalo ngabanye noma izihlahla lapha zihlanganisa irowu izitshalo ezifana imifino kanye umoba. Futhi blizkorastuschih izitshalo (isib irayisi), le ndlela asifanele.

Uhlobo ubuchwepheshe kanye nesipiliyoni sangaphambilini sohlelo ukuthambisa

uhlobo lobuchwephese kuthinta ukukhetha wokunisela indlela. Ukuvuza futhi Sprinkler kukhona ngokomthetho izindlela eziyinkimbinkimbi. Ukuthengwa imishini kudinga capital investment ezinkulu. Yabadobi ngenkasa izinhlelo engahileli ukusetshenziswa imishini eyinkimbinkimbi ukuze (amaphampu ngaphandle) yokwakha nokunakekela. Khetha indlela ukuthambisa lincike isiko wamukela ngaphakathi esifundeni noma izwe. Ukusebenzisa indlela ezazingaziwa kungaholela yezinkinga ezingalindelekile. Ukugcina imishini kungenzeka eziyinkinga bese izindleko - okusezingeni eliphezulu kuqhathaniswa nezinzuzo. Ngezinye izikhathi, kuba lula kakhulu yokuthuthukisa bendabuko ngenkasa indlela kuka ukwethula entsha ngokuphelele hhayi ihlolwe endaweni ethile.

zabasebenzi, izindleko nezinzuzo

Ukuchelela phezu kwenhlabathi - kuyinqubo isikhathi esiningi uma kuqhathaniswa imvula amaconsi njengoba kudinga eqondile endaweni yokululama, njalo kanye nasezingeni eliphezulu of inhlangano abalimi ukusebenza ohlelweni. Ngaphambi kokukhetha indlela uchelela, nezilinganiso kufanele wengeze izindleko kanye inzuzo kukho okutholakalayo.

Irrigation njengoba yigama lezokwelapha

Uyini ukunisela womphimbo nomlomo? Le nqubo ukuhlanzwa lula ukuvuvukala, ezifana umphimbo obuhlungu. Lokhu kususa amagciwane kobuso crypts ka amalaka, okuyinto enomthelela Ukuwavula kancane kancane kwegazi enempilo endaweni, umphumela ofanayo ibangelwa ngenkasa womphimbo. Kuyini futhi kungani udinga khona? Massage umphumela kunciphisa ukuvuvukala futhi kusiza ukutheleleka ukushiya umzimba. Uma nisela emphinjeni wakhe ekuqaleni kwalesi sifo, okunye ukwelashwa kuyoba ngempumelelo ngaphezulu.

Kuyini wamathumbu ngenkasa? Lena ngenye yama-decontamination indlela Kwenziwa esasikhipha ukuba emathunjini inqwaba isixazululo ahlanze pheshana gastro-emathunjini ngu ushevu ngaphambi kokuba amuncwa wumzimba. Ekuqaleni ngenkasa wamathumbu besihloselwe ukusetshenziswa njengoba kulungiselelwa preoperative, futhi phambi endoscopic noma izinqubo radiographic. Inqubo iphephile ngokuphelele. Le ndlela zokuhlanjululwa akuyona kungavunyelwe ngesikhathi sokukhulelwa.

Iqhaza uchelela ezifundeni lasendulo

Ukunisela ngenkasa kuye kwehlisa nendima enkulu ezikhathini zasendulo. Ikakhulukazi ezindaweni lapho imvula kwakungenele ukuthuthukiswa egcwele izitshalo. ngenkasa zisetshenziswa kwenziwa ethafeni yaseMesophothamiya. Izitshalo bazithela njalo ngesikhathi ekhula ngokugqugquzela amanzi ngokusebenzisa encane iziteshi uhlelo. Kuyini ngenkasa eGibhithe lasendulo? Lonke umnotho isimo kwakuxhomeke Nile amanzi notshwala. Iningi indawo ekuniseleni by imishini eyinkimbinkimbi wadala ngokusebenzisa umsebenzi onzima futhi zobunjiniyela. AbaseGibhithe lasendulo wayekwenza ngenkasa esizalweni somfula usebenzisa emfuleni ochithekile.
