Imvula Yokusanhlamvu, isikhathi selanga sesi-6 sangomhla zingama-24 (njalo ngo-Ephreli 19 kuya kumhla zingama-21), isikhathi sokugcina selanga sasentwasahlobo. Uma kuza Imvula Yokusanhlamvu, kusho ukuthi isimo sezulu esibandayo siphelile, izinga lokushisa likhuphuka ngokushesha, okuyinzuzo ekukhuleni kwezitshalo zokusanhlamvu.
Inani elifanele lemvula lizoletha isivuno esikhulu sezitshalo. Ezikhathini zasendulo imvula izala amacereal ayi-100 ukusho ukuthi ikhombisa ukubaluleka kwesimo sezulu sezolimo samanje. Ezindaweni ezimaphakathi neziphansi zoMfula Ophuzi, imvula yokusanhlamvu ayikhombisi nje ukubaluleka kwezolimo kuphela kodwa futhi ikhombisa ukuthi "imvula yasentwasahlobo ibaluleke njengamafutha".
Kungani imvula yasentwasahlobo ibaluleke kangaka? Yayihlobene nesimo sezulu. Kuyabanda futhi komile ebusika futhi imvula iyancipha, ngisho nasezindaweni ezisenyakatho, iningi lemvula liphenduka iqhwa, elingakwazi ukumuncwa kwezitshalo, okuholela esomiso sentwasahlobo esibi kakhulu. Isimo sezulu sidlala indima ebalulekile emandulo. Ukushoda kwemvula eningi kuzodala ukukhula okubi kwezitshalo kanye nokuncipha kwesivuno. Amanzi aseyivelakancane kwezolimo, esinye sezizathu yisimo sezulu, esinye isizathu wukuntuleka kwethu kwemithombo yamanzi. Ukunqamula izingqinamba zemithombo yamanzi kwezolimo, sidinga ukuthuthukisa ezolimo ngenkasa okonga amanzi.Inkasa yokonga amanzi yindlela yokunisela eyenza isivuno sibe sikhulu inani lezitshalo ngeyunithi ngayinye yamanzi okunisela ukuze kwandiswe isivuno noma inzuzo inani elincane lamanzi asetshenzisiwe. Izinyathelo eziyinhloko yilezi: ukuvimbela ukugeleza kwesiteshi, ukuchelela ngamapayipi anengcindezi encane, ukuchelela ngokuchelela, ukuchelela okuncane kanye nezinhlelo zokulawula ukuchelela.
Ukuvimbela ukuphuma kwe-canal
Ukulethwa kwamanzi ngamashaneli kuyindlela eyinhloko yokulethwa kwamanzi yokunisela emapulazini eChina. Inezinzuzo zokulethwa kwamanzi ngokushesha, izinkathi zonyaka ezinhle zokukhiqiza ezolimo, nokongiwa komhlaba. Njengamanje kungenye yezinyathelo eziyinhloko zokuchelela ukonga amanzi e-China.
AmanziIpayipi
Ukulethwa kwamanzi ngamapayipi ukusetshenziswa kwamapayipi ukuthumela amanzi ngokuqondile ensimini ukuze kuniselwe ukunciphisa ukuvuza kwamanzi kanye nokulahlekelwa ukuhwamuka ohlelweni lokuthuthwa kwamanzi emiseleni evulekile.Uma kuqhathaniswa nokulethwa kwamanzi emiseleni, ukulethwa kwamanzi ngamapayipi kunezinzuzo zokulethwa kwamanzi ngokushesha. , ukonga amanzi, ukonga umhlaba, kanye nokwanda kokukhiqizwa.
Ukuchelela nge-sprinkler
Ukuchelela nge-sprinkler ukusebenzisa amapayipi ukuthumela amanzi anomfutho endaweni yokuchelela, futhi awahlakaze abe amaconsi amanzi amancane ngokusebenzisa izifafazi, bese uwafafaza ngokulinganayo ensimini ukuze unisele izitshalo. Izinzuzo zayo eziyinhloko yilezi: umphumela obalulekile wokonga amanzi, ukwanda kwesivuno esikhulu, ukuchelela ngendlela efanayo, nokungaqini kwenhlabathi. Kwehlisa kakhulu izindleko zokuchelela kubalimi, okuhambisana nokusheshisa ukufezwa kwemishini yezolimo, ukuthuthukiswa kwezimboni, kanye nokuthuthukiswa kwesimanje.
Isifutho esincane
I-Micro-sprinkling iwuhlobo olusanda kuthuthukiswa lokuchelela ngokuchelela, olulondoloza amanzi futhi lufuthwe ngokulinganayo ezitshalweni kunokuchelela okujwayelekile kokuchela. Futhi inganwetshwa ibe uhlelo oluzenzakalelayo lokulawula, oluhlanganiswe nokusetshenziswa komanyolo wamakhemikhali ukuze kuthuthukiswe ukusebenza kahle kukamanyolo.
Ukunisela ngamaconsi
Ukuchelela nge-drip ukusetshenziswa kwamapayipi epulasitiki ukuthumela amanzi ezimpandeni zezitshalo ngokusebenzisa ama-orifices noma ama-drippers ku-capillary enobubanzi obungaba ngu-16 mm ukuchelela kwendawo. Kuyindlela ephumelela kakhulu yokonga amanzi ezindaweni ezomile nezintula amanzi, futhi izinga lokusebenzisa amanzi lingafinyelela ku-95%. Uma kuqhathaniswa ne-sprinkler irrigation, ukuchelela nge-drip kunomphumela ophezulu wokonga amanzi kanye nokwandisa isivuno. Ngaso leso sikhathi, ingahlanganiswa nokuvundisa ibe ngaphezu kokuphindwe kabili ukusebenza kahle kukamanyolo.
Nakuba amanzi engumthombo wakho konke futhi edlala indima ebalulekile ekukhuleni kwezitshalo, amanzi amaningi okunisela awanele. Amanzi amaningi azoholela ekungeneni kwe-oxygen encibilikisiwe esixazululweni senhlabathi. Amaseli ezimpande azokwenza ukuphefumula kwe-anaerobic futhi akhiqize utshwala. Inomthelela onobuthi kumaseli ezimpande, futhi ekugcineni ibangele ukubola kwezimpande ukuthi kuthinte ukukhula nokuvuthwa. Ukuze uvimbele lokhu ukuthi kungenzeki ezitshalweni kwezinye izindlu zokugcina izithombo, ungasetha ama-transmitters okushisa nomswakama amaningi ezindaweni ezingaguquki ku-greenhouse ukuze usungule Isistimu yokuqapha izinga lokushisa lokushisa kanye nomswakama we-IoT, futhi iguqule idatha elinganisiwe ngokucubungula Dlulisa idatha kuplatifomu yedatha yokuqapha eku-inthanethi ngenethiwekhi ye-GPRS. Inkundla yokudlulisa idatha yokuqapha eku-inthanethi ibona ukwamukela idatha, ukuhlunga, ukugcinwa, ukucutshungulwa, ukuhlaziya izibalo, futhi inikeza imisebenzi yesikhathi sangempela yemibuzo yedatha. Umsebenzisi angafika ngesikhathi ngokusekelwe ezingeni lokushisa lesikhathi sangempela kanye nedatha yomswakama wenzwa yokushisa nomswakama Ukusebenza ngaphakathi kwe-greenhouse kuwusizo olukhulu ekukhuleni kwezitshalo.
I-HENGKO inethimba lensizakalo yezobuchwepheshe ukuze inikeze isiqondiso sochwepheshe ukuze isize amakhasimende athole izisombululo zesevisi ye-IoT ezifanele neziphelele zokushisa nomswakama. Ngaphandle kwalokho, Kunochungechunge oluhlukahlukene lokushisa nomswakama ozikhethele lona, lungahlangabezana nezidingo zokulinganisa zezinqubo ezidingekayo zezimboni nokulawulwa kwemvelo.
