Kuwala kowala kumakhudza kwambiri ntchito za bumblebees. Ichi ndi chimodzi mwa zotsatira za kafukufuku wa ulimi wa “Fossil-free Tomato with LED” wochitidwa ndi Delphy Improvement Center, Groen Agro Control ndi Wageningen University’s Greenhouse Horticulture and Research Unit.
Maphunziro a chikhalidwe samayesa kokha mphamvu ya nyali, komanso ndi kusintha kwa nthawi yowonekera, ndipo adaphunzira zotsatira za kuwonjezeka kwa kuwonekera ndi mawotchi otsika mtengo. “Njira yozizira yatha tidasunga nthawi yowonekera kuyambira 10pm mpaka 4pm. Chifukwa chake, maola otsika mtengo ausiku amakhala owonekera kwambiri chifukwa cha masana, omwe nthawi zambiri amakhala okwera mtengo,” akufotokoza motero Stein Jochems wa Delphy.
Chotsatira cha njira yowonetsetsayi ndikuti kudulira mungu wambiri kuyenera kuchitika panja usiku. “Dzuwa likayamba kuwala, maluwawo ayamba kale kutseka. Izi zikutanthauza kuti nthawi yomwe njuchi zimatha kutulutsa mungu dzuwa ndi dzuwa ndi yaifupi,” akutero Jochems. Ngakhale njuchi zowoneka bwino masana zinali zokangalika, amayembekeza kuti njuchi zokwanira zitha kuperekedwa usiku wowala.
Ziwerengero zokhazikika sizikudziwikabe
Kaya kufuna kowonjezerako kumabweretsa maluwa abwinoko zimadalira timagulu tomwe takololedwa. Wofufuzayo akuti mphesazo zidayikidwa nthawi yamdima kwambiri ndipo posachedwapa zidzatengedwa. "Pakadali pano, manambala owerengera akuwonetsa kusiyana pang'ono pakati pa sipekitiramu yotakata kapena yokhazikika pokomera sipekitiramu yotakata." M'mbuyomu, zidapezeka kuti ma bumblebees amasiya mabokosi kale ndi mawonekedwe ambiri.
* Werenganinso: Kuunikira kocheperako kwa LED kumapereka mwayi pamsika wamakono wamagetsi
Pamene mawonekedwe ena akuwonetsa malo abwinoko, a Jochems amanena kuti ntchito zothandiza zikhoza kuganiziridwa. 'Kuphatikiza pa kukhala whim, microclimate yozungulira maluwa ndi yofunika kubzala. M'tsogolomu, ndizosangalatsa kugwira ntchito ndi chipika cha pollinator, kuunikira kwa maola angapo ndi gawo lapamwamba la zobiriwira ndi blues ndikutumiza ku nyengo yowuma kuzungulira gulu la maluwa.'
Kafukufuku wa kulima adzapitirira mpaka kumapeto kwa nyengo yakukula, ndi chimodzi mwa zolinga za chaka chino ndikugwiritsa ntchito njira yowunikira kwambiri. "Zonse za chikwama ndi zokolola," wofufuzayo akutsindika.
