NgokweNational Centers for Environmental Forecasting yase-US, umhlaka-3 Julayi bekuwusuku olushisa kakhulu emlandweni womhlaba, izinga lokushisa elivamile emhlabeni lingaphezu kuka-17 degrees Celsius ngokokuqala ngqá, lafinyelela ku-17.01 degrees Celsius. Nokho, irekhodi lahlala isikhathi esingaphansi kwamahora angu-24, laphinde lagqashuka ngoJulayi 4, lafinyelela ku-17.18°C. Ezinsukwini ezimbili nje kamuva, ngo-July 6, izinga lokushisa embulungeni yonke laphinde laqopha umlando, lephula amarekhodi ka-July 4 no-5. Izinga lokushisa elivamile lembulunga yonke elingamamitha amabili ngaphezu komhlaba lifinyelela ku-17,23°C.
Umthelela wokushisa okuphezulu emkhiqizweni wezolimo
Isimo sezulu sokushisa okuphezulu sinomthelela omkhulu ekukhiqizeni kwezolimo. Amazinga okushisa aphezulu emini azovimbela i-photosynthesis yezitshalo futhi anciphise ukuhlanganiswa nokuqoqwa koshukela, kanti ebusuku kuzosheshisa ukuphefumula kwezitshalo futhi kudle imisoco eminingi evela ezitshalweni, ngaleyo ndlela kunciphise isivuno nekhwalithi yezitshalo.
Izinga lokushisa eliphezulu lizosheshisa nokuhwamuka kwamanzi ezitshalweni. Inani elikhulu lamanzi lisetshenziselwa ukuphefumula nokushisa, licekele phansi ibhalansi yamanzi esitshalweni, okwenza isitshalo sibune futhi some. Uma singaniselwanga ngesikhathi, lesi sitshalo sizolahlekelwa amanzi kalula, some futhi sife.
Izinyathelo zokuphendula
Ukusebenzisa amanzi ukulungisa izinga lokushisa elivamile lezitshalo inketho elula kakhulu. Ngakolunye uhlangothi, ingakwazi ukuxazulula inkinga yokunisela, futhi ngesikhathi esifanayo, ingakwazi ukulungisa izinga lokushisa futhi inikeze indawo efanelekayo yokukhula kwezitshalo.
1. Izitshalo zasenyakatho
Kunezindawo eziningi ezinkulu zamapulazi angenalutho enyakatho, futhi akufanelekile ukusebenzisa i-shading noma ukuchelela okwenziwayo ukupholisa. Lapho izitshalo ezivulelekile njengommbila, ubhontshisi wesoya, nokotini zihlangabezana namazinga okushisa aphezulu phakathi nezikhathi zokukhula ezibucayi, kufanele ziniselwe ngendlela efanele ukuze kwehlise izinga lokushisa eliphansi futhi kukhuthaze ukumuncwa kwamanzi ukuze kuvinjelwe umonakalo obangelwa ukuphefumula okukhulu kwamanzi kunokumuncwa kwezimpande.
Ezindaweni ezisenyakatho lapho ikhwalithi yamanzi icacile, amaphampu amanzi ahlanzekile e-centrifugal angasetshenziswa ukusiza ukuchelela kwezolimo. Iphampu yokuzilungisa inomthamo omkhulu wokugcina amanzi emgodini kanye nezinga eliphezulu elithwala umthwalo we-inlet yamanzi kanye nama-flange wokuphuma. Ingathembela ekuzilungiseleleni kwayo okuphakeme ehlobo lapho ilanga libalele. ukusebenza, ingakwazi ukwethula ngokushesha amanzi omfula ensimini, isize ukuthuthukisa isimo sezulu sendawo, futhi ivikele izitshalo emazingeni okushisa aphezulu.

2.Izitshalo zaseNingizimu
Eningizimu, irayisi nama-yam yizilimo eziyinhloko ehlobo. Lezi yizitshalo ezidinga ukuchelela endaweni enkulu. Akwenzeki ukusebenzisa ukupholisa i-greenhouse kulezi zitshalo, futhi zingalungiswa kuphela ngamanzi. Lapho uhlangabezana namazinga okushisa aphezulu, ungasebenzisa indlela yokunisela amanzi angajulile njalo, ukuchelela emini kanye nokukhipha amanzi ebusuku, okunganciphisa ngempumelelo izinga lokushisa ensimini futhi kuthuthukise insimu ye-microclimate.
Indawo elinywayo eningizimu ihlakazekile futhi imifula ngokuvamile iqukethe udaka namatshe. Ngokusobala akufanelekile ukusebenzisa iphampu yamanzi ehlanzekile. Singakhetha iphampu ye-centrifugal ye-self-priming indle. Uma kuqhathaniswa nephampu yamanzi ahlanzekile, inomklamo obanzi wesiteshi sokugeleza futhi inekhono eliqinile lokudlula indle. Kufanele kukhethwe. I-304 stainless steel welded shaft ingathuthukisa ngempumelelo ukukhuthazela futhi ivumelane nezimo zokusebenza zasekuseni nakusihlwa ensimini. Emini, amanzi omfula angeniswa ukuze asize ukupholisa futhi agcwalise umthombo wamanzi odingekayo ekukhuleni. Ebusuku, amanzi amaningi kakhulu ensimini akhishwa ngepompo ukuze kugwenywe ukufa kwezimpande zezitshalo ngenxa yokuntuleka komoya-mpilo.
Eminyakeni yamuva, izinguquko ezimbi kakhulu zesimo sezulu ziye zaqhubeka zithinta ukukhiqizwa nokuphila. Kokubili isomiso nezikhukhula kuye kwenzeka kaningi. Iqhaza lamaphampu amanzi seligqame kakhulu. Bangakwazi ukukhipha amanzi ngokushesha futhi banikeze ukuchelela okusheshayo ukuvikela ezolimo kanye nokwenza ngcono ukusebenza kahle kokulima.
