Kumpoto kwa dziko lapansi, Canada ndi yotchuka chifukwa cha malo ake aakulu ndi malo okongola achilengedwe. Komabe, m’dziko lino, ulimi wowonjezera kutentha ukulemba mutu watsopano waulimi mwabata koma mosonkhezera, kukhala ngale yonyezimira pa chitukuko cha ulimi wamakono.
1. Kuphatikizika koyenera kwa chilengedwe chapadera chachilengedwe ndi greenhouses
Canada ili ndi zachilengedwe zambiri, ndipo mpweya wabwino ndi madzi abwino ndi maziko abwino kwambiri a ulimi. Ngakhale nyengo yozizira, uwu wakhala mwayi kwa ulimi wowonjezera kutentha kusonyeza luso lawo. Nyumba zosungiramo zomera ku Canada zili ngati madoko ofunda, zoteteza mbewu ku kuzizira. Ngakhale kuti kuwala kwadzuwa kumakhala kochepa kwambiri m'nyengo yozizira ya ku Canada, nthawi yokwanira ya dzuwa imatengedwa ndi wowonjezera kutentha ndikusandulika kukhala mphamvu yokulitsa mbewu. Panthawi imodzimodziyo, malo akuluakulu pano amapereka malo okwanira kuti amange nyumba yaikulu yotenthetsa kutentha, popanda kuganiza kwa danga, zomwe zimapangitsa kuti nyumbayi ikhale yasayansi komanso yololera.
2. Ukadaulo wopitilira muyeso wowonjezera kutentha ndi zida zatsopano
Kulowa mu greenhouse yaku Canada kuli ngati kulowa mu labotale yodzaza ndiukadaulo wapamwamba kwambiri. Nyumba zobiriwira pano zimagwiritsa ntchito zida zomangira zapamwamba kwambiri ndipo zimakhala ndi ntchito yabwino yotchinjiriza, zomwe zingachepetse kutaya kutentha m'malo ozizira akunja. Makina owongolera kutentha ndi olondola kwambiri. Kaya ndi usiku wozizira kapena usana wotentha pang'ono, kutentha kwa wowonjezera kutentha kumasungidwa pamalo abwino kwambiri kuti mbewu zikule.
Njira yothirira ndi yapadera. Mothandizidwa ndi luso lamakono la sensa, chinyezi cha nthaka ndi zofunikira za madzi a mbeu zitha kuyang'aniridwa mu nthawi yeniyeni, potero kukwaniritsa ulimi wothirira ndendende. Izi sizimangopewa kuwononga madzi, komanso zimatsimikizira kuti mbewu iliyonse ingapeze madzi okwanira okwanira. Kuphatikiza apo, makina owonjezera a carbon dioxide amawonjezera kuchuluka kwa mpweya woipa mu wowonjezera kutentha munthawi yake komanso moyenera malinga ndi zosowa za photosynthesis ya mbewu, monga kuyatsa "turbocharger" kuti mbewu zikule mwachangu, ndikuwongolera zokolola komanso mtundu wa mbewu.
3. Kubzala mbewu mochuluka komanso kosiyanasiyana komanso kutulutsa kwapamwamba
M'malo obiriwira obiriwira ku Canada, mbewu zosiyanasiyana zimabzalidwa, zomwe zikuwonetsa zowoneka bwino. Zamasamba zatsopano ndizofunikira kwambiri pa greenhouse. Kuchokera ku letesi wonyezimira, nkhaka zowutsa mudyo mpaka tomato wofiira, masambawa amatha kuperekedwa kumsika chaka chonse pansi pa chisamaliro cha wowonjezera kutentha.
Kulima maluwa ndi ntchito yofunika kwambiri mu greenhouses. Ndi malo abwino operekedwa ndi wowonjezera kutentha, mitundu yonse ya maluwa, monga maluwa okongola ndi maluwa okongola ndi oyera, afika pamiyezo yapamwamba kwambiri pamtundu, kukula ndi alumali. Maluwa apamwambawa samangokwaniritsa zofuna za msika wapakhomo zokongoletsa maluwa ndi mphatso, komanso amatumizidwa kumayiko ena ambiri, omwe amakhala ndi malo ofunika kwambiri pamsika wamaluwa wapadziko lonse.
Palinso minda ya zipatso, monga mabulosi okoma ndi owawasa, sitiroberi atsopano ndi otsekemera ndi zipatso zina za mabulosi, zomwe zimakula bwino m'nyumba zobiriwira. Chifukwa cha kuwongolera kwa chilengedwe cha wowonjezera kutentha, kuchuluka kwa shuga kwa zipatso kumakhala kokwanira, kukoma kumakhala kokoma kwambiri, ndipo zakudya zimasungidwa bwino.
4. Mchitidwe wozama wa lingaliro lachitukuko chokhazikika
Canadian greenhouse Agriculture ndi katswiri wodalirika wa chitukuko chokhazikika. Pankhani yogwiritsira ntchito mphamvu, nyumba zambiri zobiriwira zayamba kugwiritsa ntchito kwambiri mphamvu zoyera, monga mphamvu ya geothermal ndi mphamvu ya dzuwa. Monga gwero lokhazikika la mphamvu, mphamvu ya geothermal imapereka kutentha kosalekeza ku nyumba zobiriwira kudzera m'makina osinthana ndi geothermal, kuchepetsa kudalira mafuta achilengedwe. Ma solar akuwonetsanso mphamvu zawo ku Canada dzuwa, kutembenuza mphamvu ya dzuwa kukhala mphamvu yamagetsi kuyendetsa zida zosiyanasiyana m'malo obiriwira.
Ponena za kayendetsedwe ka kayendetsedwe ka madzi, kuwonjezera pa ndondomeko yothirira bwino kuti achepetse zinyalala, kusonkhanitsa madzi a mvula ndi makina obwezeretsanso agwiritsidwanso ntchito kwambiri. Madzi a mvula omwe amasonkhanitsidwa amayeretsedwa ndikugwiritsidwanso ntchito m'thirira, zomwe zimapangitsa kuti madzi agwiritsidwe ntchito bwino komanso amachepetsa kuthamanga kwa madzi achilengedwe. Chitsanzo chachitukuko chokhazikikachi sichimangotsimikizira chitukuko chokhazikika cha ulimi wowonjezera kutentha kwa Canada, komanso chimapereka chitsanzo chabwino kwambiri cha ulimi wapadziko lonse lapansi kuti athane ndi kusintha kwa nyengo ndi kusowa kwa zinthu.
5. Zothandizira zabwino pazachuma ndi anthu
Ulimi wowonjezera kutentha ku Canada uli ndi phindu lalikulu komanso labwino pachuma cha dziko komanso anthu. Pazachuma, kukwera mtengo kwa zinthu zaulimi wowonjezera kutentha kwadzetsa ndalama zambiri pazaulimi. Zogulitsa zaulimi zapamwambazi zimakhala zopikisana kwambiri m'misika yapanyumba ndi yakunja, ndipo mphamvu zawo zogulira kunja zikuchulukirachulukira. Panthawi imodzimodziyo, ulimi wowonjezera kutentha kwayendetsa chitukuko cha mafakitale okhudzana, monga kupanga zida zaulimi, kufufuza ndi chitukuko cha mbewu, feteleza ndi mankhwala ophera tizilombo, ndi zina zotero, zomwe zimapanga mafakitale akuluakulu komanso athunthu.
Pa chikhalidwe cha anthu, ulimi wowonjezera kutentha wapanga mwayi wochuluka wa ntchito. Kuyambira pakumanga ndi kukonza nyumba zobiriwira mpaka kubzala, kutola, kulongedza ndi kugulitsa mbewu, pamafunika antchito ambiri. Izi zimapereka ntchito zokhazikika kwa okhala m'deralo, kuwongolera kuchuluka kwa ndalama zomwe amapeza, komanso kumalimbikitsa chitukuko ndi bata la anthu amderalo.
Ulimi wowonjezera kutentha ku Canada, wokhala ndi maubwino ake apadera, umaphatikiza zinthu zambiri monga chilengedwe, ukadaulo, ndi chitukuko chokhazikika, kukhala chitsanzo chaulimi wamakono. Sizinangowonjezera mphamvu pakukula kwaulimi ku Canada, komanso zapereka chidziwitso chofunikira komanso chilimbikitso cha chitukuko chamtsogolo chaulimi wapadziko lonse lapansi.
