Nkhani - Ndi Mavuto Obisika Otani a Greenhouses?

Greenhousesndi mbali yofunika kwambiri ya ulimi wamakono. Iwo amapereka achilengedwe cholamulidwazomwe zimathandiza kuti mbewu zikule bwino, mosasamala kanthu za nyengo yakunja. Ngakhale kuti zimabweretsa zopindulitsa zambiri, nyumba zobiriwira zimakhalanso ndi zinthu zosiyanasiyana zachilengedwe komanso zachuma. Mavutowa sangawonekere msanga, koma pamene ulimi wowonjezera kutentha ukukula, zikuwonekera kwambiri. Ndiye, ndi zovuta zotani zobisika ndi greenhouses?

1. Kugwiritsa Ntchito Mphamvu ndi Carbon Footprint

Kuti mbewu zizikhala zofunda, nyumba zobiriwira nthawi zambiri zimafunikira mphamvu zambiri, makamaka m'nyengo yozizira. Makina otenthetsera omwe amagwiritsidwa ntchito m'malo obiriwira amawononga gasi wambiri kapena malasha, zomwe zimapangitsa kuti mpweya uwonjezeke. Pamene zotsatira za kusintha kwa nyengo zikuwonekera kwambiri, kuyendetsa mphamvu zogwiritsira ntchito magetsi m'nyumba zosungiramo zomera zakhala vuto lalikulu. Kuchepetsa kugwiritsa ntchito mphamvu ndikusintha magwero amphamvu oyeretsa ndikofunikira. Makampani ngati Chengfei Greenhouseakufufuza matekinoloje osagwiritsa ntchito mphamvu kwambiri kuti akankhire bizinesiyo kuti ikhale yokhazikika.

2. Kugwiritsa Ntchito Madzi ndi Kuwonongeka kwa Zida

Mbewu mu greenhouses zimafunika kuthirira nthawi zonse kuti mukhale ndi chinyezi choyenera, chomwe chingakhale cholemetsa chachikulu pamadzi, makamaka m'madera omwe akukumana ndi kusowa kwa madzi. M’madera amene madzi ndi ochepa, kumwa kumeneku kungawonjezere vutolo. Chifukwa chake, kuwongolera kasamalidwe ka madzi muulimi wowonjezera kutentha ndikofunikira kuti tithane ndi vuto lamadzi padziko lonse lapansi.

3. Kuwonongeka Kwachilengedwe ndi Kuwonongeka Kwachilengedwe

Ngakhale mbewu m'ma greenhouses zimakula mwachangu chifukwa cha zinthu zomwe zimayendetsedwa, kukula kwamtunduwu kumatha kukhala ndi zotsatira zoyipa pazozungulira. Nthawi zina, ulimi wa monoculture m'malo obiriwira obiriwira umachepetsa zamoyo zosiyanasiyana ndikusokoneza zachilengedwe. Ngati mapangidwe ndi kasamalidwe ka greenhouses sizimaganiziridwa ndi chilengedwe, zitha kuthandizira kuwononga chilengedwe kwanthawi yayitali.

4. Kugwiritsa Ntchito Mankhwala ndi Feteleza

Pofuna kuthana ndi tizirombo ndi matenda omwe amakhudza mbewu zobiriwira, mankhwala ophera tizilombo ndi feteleza amagwiritsidwa ntchito nthawi zambiri. Ngakhale kuti mankhwalawa ndi othandiza popewera kuwonongeka, kugwiritsidwa ntchito kwa nthawi yaitali kungayambitse kuwonongeka kwa nthaka, kuipitsidwa ndi madzi, ndi zina za chilengedwe. Kudalira mankhwala pofuna kuteteza mbewu kuyenera kusinthidwa ndi njira zaulimi zokhazikika.

5. Nkhani Zogwiritsa Ntchito Malo

Pamene teknoloji ya greenhouses ikupita patsogolo, nyumba zosungiramo zomera zazikulu zikutenga malo ambiri, makamaka m'madera omwe alibe malo ochepa. Kumanga nyumba zosungiramo zomerazi kungawononge malo olimapo kapena malo achilengedwe, zomwe zingabweretse kuwononga nkhalango ndi kusokoneza zachilengedwe. Kuyang'ana pakati pa kukula kwaulimi ndi kuteteza chilengedwe ndikofunikira kuti pakhale ulimi wokhazikika.

6. Kusintha ku Kusintha kwa Nyengo

Kusintha kwanyengo kumabweretsa zovuta zatsopano pakugwira ntchito kwa greenhouse. Zochitika zanyengo yoopsa, monga mafunde a kutentha ndi mphepo yamkuntho, zikuchulukirachulukira ndipo zikuchulukirachulukira. Izi zimawonjezera kukakamiza kwa zomanga za greenhouses ndi kuthekera kwawo kukhalabe ndikukula kokhazikika. Ma greenhouses amayenera kupangidwa poganizira za nyengo yamtsogolo, kuti athe kupirira kusinthaku.

7. High Initial Investment

Kumanga nyumba yotenthetsera kutentha kumafuna ndalama zambiri zoyambira, kuphatikizapo ndalama zogulira zitsulo, magalasi oonekera kapena zovundikira zapulasitiki, ndi makina othirira okha. Kwa alimi ang'onoang'ono, mtengo wapamwambawu ukhoza kukhala wotsika kwambiri. Chotsatira chake, ulimi wowonjezera kutentha sungakhale wotheka kwa aliyense, makamaka m'madera omwe alibe chuma.

Ngakhale nyumba zobiriwira zimagwira ntchito yofunika kwambiri paulimi wamakono, ndikofunikira kuzindikira ndikuthana ndi zovuta zomwe zimabweretsa. Kuchokera pakugwiritsa ntchito mphamvu mpaka kugwiritsa ntchito zinthu, komanso kuwononga zachilengedwe mpaka kukwera mtengo, mavutowa akuwonekera kwambiri pamene ulimi wowonjezera kutentha ukukula. Tsogolo la ulimi wowonjezera kutentha lidzadalira momwe timalinganiza kupanga kwakukulu ndi kusunga chilengedwe.

Takulandilani kukambilananso nafe.
