Chifukwa chiyani alimi akuluakulu a mbatata aku Kenya amabzala chikasu kuti ateteze mbewu zawo

Yendetsani kumadera olima mbatata ngati Narok, Nyandarua, Nakuru and Meru ndipo muwona china chodabwitsa: minda yachikasu yonyezimira ya canola ikuphuka komwe mbatata nthawi ina idalipo. Ngakhale zitha kuwoneka ngati kukongola, mbewu yagolide iyi ikugwira ntchito yayikulu kumbuyo - makamaka kwa alimi omwe akuvutika ndi kuchepa kwa zokolola za mbatata chifukwa cha tizirombo ndi matenda osatha.

Mdani wambatata nambala 1: Matenda oyambitsidwa ndi nthaka

Mbatata zaku Ireland ndizowopsa kwambiri matenda oyambitsidwa ndi nthaka ngati Rhizoctonia solani, Verticillium dahliae ndi nematodes - owukira osawoneka omwe amawononga mizu, amachepetsa kukula kwa tuber ndi zokolola za slash. M'kupita kwa nthawi, kubzala mbatata mosalekeza (monocropping) kumapangitsa vutoli kukhala lokulirapo, chifukwa matenda amakula nyengo ndi nyengo.

Koma canola - msuweni wa kabichi ndi kale (Brassicaceae (Cruciferae) banja) - zikutsimikizira kukhala a osintha masewera.

Chitetezo chachilengedwe cha Canola: Biofumigation

Mizu ya canola ikakula, imatulutsa zinthu zomwe zimadziwika kuti glucosinolates. Izi zimagawanika kukhala biofumigants zachilengedwe - zinthu zomwe zimakhala ngati zofewa, zopha tizilombo m'nthaka.

Ma biofumigants awa awonetsedwa kuti:

• Kupondereza rhizoctonia, chifukwa cha black scurf ndi tsinde
• Chepetsani kuchuluka kwa anthu nematode, zomwe zimawononga mizu ya mbatata
• Kuswa moyo wa Verticillium ndikufuna tizilombo toyambitsa matenda

Chotsatira? Dothi labwino ndi mbewu za mbatata zathanzi.

"Tikukonzekera kuzungulira ndi Canola"

"Ndikukonzekera kutembenuza mbatata yanga ndi canola," akutero Mose, mlimi wa mbatata ku Mau Narok. “Takhala ndi vuto la matenda komanso udzu wouma khosi.

Dongosolo lake likuwonetsa machitidwe ambiri: Canola/Rapeseed (brassica napus) kukhala a wokondedwa wokondedwa kulima mbatata bwino kudzera kasinthasintha.

Momwe kasinthasintha kumagwirira ntchito

Mukatembenuza mbatata ndi canola, mumaphwanya njira yomwe tizilombo toyambitsa matenda timadalira kuti tipulumuke. Mizu ya Canola imakumba mozama, mpweya m'nthaka ndi kulimbikitsa organic kanthu. Mbewu ikafa ndikuwola, imasiya zakudya monga sulfure ndi boroni - zofunika kuti mbatata kukula.

M'malo mobzalanso m'malo "otopa" odzaza ndi matenda, alimi tsopano akukonzanso minda yawo - ndipo mbewu za mbatata zomwe zimatsatira zikuwonetsa kukula kwamphamvu, zizindikiro zochepa za matenda ndi zokolola zabwino.

Agronomic thandizo

Agronomists akhala akufufuza izi mozama. Malingana ndi mayesero a m'munda ndi zochitika za alimi:

• Zokolola za mbatata kuwonjezeka kwambiri pambuyo pa kuzungulira kwa canola.
• Alipo kufunikira kochepa kwa fungicides ndi nematicides, kuchepetsa ndalama zolowetsamo.
• Mbewu zimatuluka mofanana ndi kuchepa kwa mizu ndi zoyeretsa tubers pa nthawi yokolola.

Ngakhale kuthamanga kwa udzu kumatsitsidwa, makamaka kwa ryegrass ndi brome udzu, amene nthawi zambiri samva mankhwala ophera udzu.

Alimi a mbatata, zindikirani

Ngati mukukula mbatata ndikulimbana ndi matenda kapena tizilombo toyambitsa matenda, kuzungulira ndi canola kungakhale koyenera. kukonza kosavuta komanso kwanzeru kwambiri kupezeka. Nazi mwachidule momwe mungayambitsire:

• Kukula canola mu nyengo yopuma kapena pakati pa kasinthasintha wa phala.
• Siyani maluwa kwathunthu ndi kulilima, kapena kututa mbewu ndi mafuta.
• Tsatirani ndi mbeu yanu ya mbatata nyengo yotsatira phindu lalikulu.

malingaliro Final

Canola si duwa lowala lachikasu m'munda - ndi chida champhamvu chamoyo pobwezeretsa bwino nthaka yanu ndikuteteza mbatata yanu kwa adani osawoneka. Pamene alimi ku Kenya akukumbatira ulimi wanzeru panyengo, canola mofulumira akukhala chimodzi mwa zida zanzeru kwambiri pomenyera nkhondo mbatata zathanzi, zolimba.

Ndiye nthawi ina mukadzawona minda yachikasu yonyezimira, kumbukirani: ndi yokongola kwambiri - ikumenyera ma spuds abwinoko!
