Ulimi Wothirira ndi Kudyetsa Mvula
Pali njira ziwiri zazikulu zomwe alimi ndi alimi amagwiritsira ntchito madzi a ulimi kulima mbewu:

ulimi wodyetsedwa ndi mvula
kuthirira
Ulimi wothira mvula ndi njira yachilengedwe yogwiritsira ntchito madzi m'nthaka kudzera mu mvula yachindunji. Kudalira mvula sikungathe kuipitsa chakudya, koma kusowa kwa madzi kungachitike mvula ikachepa. Kumbali ina, madzi opangidwa amawonjezera chiopsezo cha kuipitsidwa.

chithunzi cha ma sprinkler othirira minda
Kuthirira ndi njira yopangira madzi m'nthaka kudzera m'mapaipi osiyanasiyana, mapampu ndi njira zopopera. Kuthirira nthawi zambiri kumagwiritsidwa ntchito m'malo omwe mvula imagwa mosakhazikika kapena nthawi youma kapena chilala chomwe chikuyembekezeka. Pali mitundu yambiri ya njira zothirira momwe madzi amagawidwa mofanana m'munda wonse. Madzi othirira amatha kuchokera pansi panthaka, akasupe kapena zitsime, madzi pamwamba, mitsinje, nyanja kapena malo osungiramo madzi, kapena ngakhale magwero ena monga madzi otayidwa kapena madzi ochotsedwa mchere. Chifukwa chake, ndikofunikira kuti alimi ateteze magwero awo amadzi aulimi kuti achepetse kuipitsidwa. Monga momwe zimakhalira ndi kuchotsa madzi apansi panthaka, ogwiritsa ntchito madzi othirira ayenera kusamala kuti asatulutse madzi apansi panthaka mwachangu kuposa momwe angabwezeretsedwere.

pamwamba pa tsamba

Mitundu ya Njira Zothirira
Pali mitundu yosiyanasiyana ya njira zothirira, kutengera momwe madzi amagawidwira m'minda yonse. Mitundu ina yodziwika bwino ya njira zothirira ndi iyi:

kuthirira pamwamba
Madzi amafalikira pamtunda pogwiritsa ntchito mphamvu yokoka ndipo palibe mapampu amakina omwe amagwiritsidwa ntchito.

kuthirira kwa m'deralo
Madzi amaperekedwa ku chomera chilichonse pa mphamvu yochepa kudzera mu netiweki ya mapaipi.

kuthirira madzi pang'ono
Mtundu wa ulimi wothirira womwe umapereka madontho a madzi ku mizu ya zomera pafupi ndi mizu. Mu ulimi wothirira uwu, madzi amatuluka m'nthaka ndi madzi otuluka m'nthaka.

chopopera madzi
Madzi amaperekedwa kudzera m'ma sprinkler kapena mipeni yopopera mpweya kuchokera pakati pa malo ogwirira ntchito kapena m'ma sprinkler omwe amayendetsedwa ndi ma platforms oyenda.

Kuthirira Pakati Pafupi
Madzi amagawidwa ndi makina opopera madzi omwe amayenda mozungulira pa nsanja zamawilo. Njira imeneyi ndi yofala m'malo otsetsereka ku United States.

Ulimi wothirira woyenda mbali zonse
Madzi amagawidwa kudzera m'mapaipi angapo, iliyonse ili ndi gudumu ndi zida zothira madzi zomwe zingazunguliridwe ndi manja kapena pogwiritsa ntchito makina apadera. Chothira madzi chimasuntha mtunda winawake pamunda kenako chimafunika kulumikizidwanso ku mtunda wina. Dongosololi nthawi zambiri limakhala lotsika mtengo koma limafuna ntchito yambiri kuposa machitidwe ena.

Ulimi wothirira wachiwiri
Pokweza tebulo la madzi, madzi amafalikira pamtunda kudzera mu njira ya malo opopera madzi, ngalande, zipata ndi ngalande. Mtundu uwu wa ulimi wothirira umagwira ntchito bwino kwambiri m'madera omwe madzi amakhala ambiri.

kuthirira ndi manja
