Phunziro: Kulima kwachilengedwe kumakulitsa kusiyanasiyana kwa mbewu ndi 230%

Pazaka khumi zoyeserera kwakanthawi, gulu lofufuza, lotsogozedwa ndi malo oyenerera ku Switzerland pakufufuza zaulimi, Agroscope, adazindikira mwatsatanetsatane momwe machitidwe anayi olimilira olima amakhudzira chilengedwe, zokolola komanso chuma.

Zotsatira zake zidasindikizidwa posachedwa mu nyuzipepala ya "Science Advances". Nayi chidule cha zofunikira kwambiri kuchokera kulumikizano wa Agroscope:

• Njira zolimidwa zolimidwa mwachilengedwe zimakhala zabwino kuwirikiza kawiri zachilengedwe monga kulima wamba.
• Munda womwe umalimidwa molingana ndi malangizo amtundu wa organic umawonetsa mitundu ingapo ya 230 ya mitengo pamwamba pazomera kuposa yomwe imalimidwa moyenera.
• Maperesenti 90 enanso anyongolotsi anapezeka m'nthaka m'malo olimidwa mwinanso ma 150% ena m'minda popanda kugwiritsa ntchito mapulawo.
• Poyerekeza ndi dothi lolimidwa kawirikawiri, kuchepa kwa mapula ndi mitundu iwiri yolimidwa bwino kumachita bwino ndi 46 mpaka 93% yocheperako.

Zotheka kukonza zokolola

"Achilles chidendene" cha ulimi wam'madzi umadziwonetsera wokha potengera zokolola, malinga ndi omwe adalemba kafukufukuyu: "Kuyesera kwanthawi yayitali kumatsimikizira kuti ulimi wamtundu (wolimidwa komanso wosaphimbidwa) umakhala wopanda phindu. Zokololazo zinali zocheperako 22% poyerekeza ndi njira wamba zopangira ndi khasu. Chimodzi mwa zifukwa izi ndikuletsa feteleza wopangira ndi mankhwala opangira mankhwala. "

Zotsatirazi zitha kusinthidwa, mwachitsanzo, ndikuchulukitsa kwamitengo yosagonjetsedwa komanso kuteteza mbewu.

Bmafuta okwanira "oyenera"

Ponseponse, akatswiri akuti: Komabe, malinga ndi momwe zinthu zimayendera, ulimi wamasamba ndi njira yosungira nthaka yopanda ulimi ndizoyenerana bwino ndi zokolola komanso chilengedwe. "

Pakafukufukuyu, njira zinayi zolimira kuminda yakunja kwa Zurich zidafaniziridwa: ulimi wamba wokhala ndi khasu, ulimi wamba wopanda khasu (no-till), ulimi wolima ndi pulawo komanso wolima wochepetsedwa.
