Nkhaniyi ikufotokoza za kufunika kothirira madzi opopera madzi pa kuthirira kwa madzi osefukira ndi kuthirira kothirira, kumvetsetsa zoyambira monga kuthamanga kwa ntchito komanso kugawa bwino madzi kuti mbewuyo ikolole bwino.
Kuthirira kumawonedwa ngati njira yofunikira pakulima mbewu muulimi.Madzi ogwiritsidwa ntchito pa nthawi yake komanso oyenera kubzala mbewu amabweretsa zokolola zambiri.Madzi ochulukirapo amatha kuwononga, pomwe kuthira madzi ochepa kumachepetsa zokolola.Choncho, m'pofunika kusankha njira yoyenera kutengera pakatisprinkler ulimi wothirirandi kuthirira madzi osefukira kuti apereke zokolola zabwino komanso ndalama.
Kuthirira madzi osefukira ndi imodzi mwa njira zakale kwambiri zogwiritsira ntchito madzi m'munda momwe madzi amaponyedwa kapena kutsanulidwa m'munda waulimi kapena m'munda wa zipatso ndipo amaloledwa kuti alowe pansi kapena kutuluka.Amabwerezedwa ngati pakufunika.Ndizosagwira ntchito kwambiri koma ndizotsika mtengo chifukwa pali ndalama zochepa.Madzi akanakhala ndi mtengo woyenerera, ulimi wothirira woterewu ukanakhala woyamba kupita.Tsoka ilo, chifukwa cha mtengo wotsika wazinthu zamtengo wapatalizi, njirazi zidakalipo.
Vuto lina lalikulu la ulimi wothirira madzi osefukira ndi lakuti madzi sagwiritsidwa ntchito mofanana pa zomera zonse.Zomera zina zimatha kupeza madzi ochulukirapo, ndipo zina zimachepa kwambiri, zomwe zimapangitsa kuti mbewu zisamakule m'munda ndipo zokolola za alimi zimachepa kwambiri.
Kuthirira madzi ndi nkhani yokhudzana ndi ulimi wothirira madzi osefukira.Itha kuletsa kukula kwa mbewu ndikuyichedwetsa mpaka madzi ochulukirapo atuluka kapena auma kuchokera pamizu.
Mthirira wothirira ndi njira yoperekera ulimi wothirira ngati mvula ku mbewu.Popeza madzi saloledwa kuyenda pamwamba pa nthaka, kutaya madzi ndi kugawa kosagwirizana kwa madzi kumathetsedwa.Chifukwa chake, poyerekeza ndi njira zothirira pamtunda, kuthirira kwakukulu kumatheka mu njira yothirira yothirira madzi.
Tikayerekeza ulimi wothirira wothirira ndi kuthirira kusefukira, pafupifupi 20-40% ya madzi amatha kupulumutsidwa ndi 10-30% ya zokolola.
Ubwino wa ulimi wothirira sprinkler ndi motere:
- Mbewu imakula bwino lomwe pamapeto pake imakulitsa mtundu wake.
- Madzi ochepa amafunikira kuposa kuthirira kwa madzi osefukira.
- Kukula kwa mizu kumathamanga kwambiri komanso mwachangu.
- Kumwa feteleza ndikokwera kwambiri kuposa kuthirira kwa madzi osefukira.Pafupifupi 90% ya feteleza amatengedwa ndi mbewu mu ulimi wothirira.
- Zokolola zimachuluka mu ulimi wothirira sprinkler chifukwa cha kugawa mofanana madzi.
- Sprinkler system ndiyosavuta kukhazikitsa komanso yotsika mtengo.
- Nthawi, ntchito, ndi mtengo wokonza zimasungidwa mu ulimi wothirira wothirira.
Malo ochulukirapo omwe amathirira mthirira amatha kubweretsa zokolola zambiri kapena zokolola kuti zikwaniritse zosowa za anthu.Zokolola zambiri zingapangitse alimi kupeza ndalama zambiri.Zikanapereka mwayi wochuluka wa ntchito kwa iwo.Ndalama zawo zowonjezera zimatha kuwapatsa ndalama zambiri kuti apititse patsogolo ntchito zomwe si zaulimi.
Pali ma sprinkler ambiri omwe amapezeka pamsika.Ambiri amapangidwa ndi mkuwa, aluminiyamu, zinki, ndi mapulasitiki a engineering.
Samalani posankha chowaza.Makatalogu ambiri opanga sprinkler amapereka chidziwitso cha magwiridwe antchito ndi mawonekedwe azinthu zawo.Chifukwa chake, ndikofunikira kuphunzira kabukhu kamene kamanena za mtundu ndi kukula kwa chowaza, manja onyamula ndi ulusi wake (wamwamuna kapena wamkazi), kukula kwa nozzle ndi mtundu wake, ngodya ya trajectory, ndi zinthu zina zofunika monga masika achitsulo chosapanga dzimbiri. ndi shaft, ntchito yotheka, etc.
Katundu yemweyo amapereka tebulo la magwiridwe antchito a aliyensemphamvu sprinklerndi ma nozzles osiyanasiyana.Kachitidwe ka sprinkler akufotokozedwa ndi kuchuluka kwa kuthamanga kwake, kutulutsa, mtunda wa kuponyera, kagawidwe kake kagawidwe kakupopera, ndi kuchuluka kwa ntchito.Kuchuluka konyowa konyowa ndi sprinkler kumadalira kuthamanga kwa ntchito, ngodya ya sprinkler trajectory, ndi mapangidwe a nozzle.
Pamene sprinkler ikugwira ntchito motsika kwambiri kuposa momwe wopanga amachitira, kukula kwa dontho kudzakhala kochulukirachulukira madzi amatuluka kuchokera muzokonkha.Izi zidzasokoneza kagawidwe kake ka madzi zomwe zimapangitsa kuchepa kwa zokolola chifukwa cha kusafanana bwino ndikusiya malo owuma m'munda.Pomwe, ngati sprinkler ikugwira ntchito mothamanga kwambiri kuposa momwe wopanga amanenera, kukula kwa dontho kumacheperako ndipo m'mimba mwake wonyowawo udzawonjezeka.Kutengeka kwa mphepo kudzakhala kochulukira pa madontho omwe angapangitse kuti kusagawa bwino kufanane.Chowazacho chiyenera kuyenda pakati pa mphamvu yogwiritsira ntchito monga momwe zasonyezedwera ndi kupanga kuti zigwirizane bwino ndi kugawa bwino ndikupeza zokolola zambiri.
