No Matt Cutull ka ʻōlelo aʻo, ke kaukaʻi kumu o ka ʻepekema mea kanu ma ka Clemson Coastal Research and Education Center.Ua hōʻike ʻo Cutulle a me nā mea noiʻi mahiʻai ʻē aʻe i nā ʻenehana "hoʻokele weed hoʻohui" i kahi papa hana hou ma Clemson Madron Convention Center a me Student Organic Farm.
E hoʻokūkū nā nāhelehele me nā mea kanu no nā meaʻai o ka lepo, e hoʻolilo ana i $32 biliona i ka lilo o nā mea kanu i kēlā me kēia makahiki, wahi a Cutulle.Hoʻomaka ka hoʻomalu ʻana i ka mauʻu i ka wā e ʻike ai ka poʻe mahiʻai i kahi manawa ʻole o ka mauʻu, he manawa koʻikoʻi i ka wā ulu i ka wā e ulu ai ka mauʻu i ka nui o ka pau ʻana o ka hua, wahi āna.
"Hiki ke ʻano like ʻole kēia manawa ma muli o ka mea kanu, ke ʻano o kona ulu ʻana (hua a hoʻololi ʻia paha), a me nā ʻano o nā mauʻu i kēia manawa," wahi a Cutulle."ʻEono pule ka manawa kī ʻole o ka weed-free conservative, akā eia hou, hiki ke ʻokoʻa kēia ma muli o ka mea kanu a me nā mauʻu i kēia manawa."
ʻO ka Critical Weed Free Period kahi wahi i ka wā ulu i ka mālama ʻana i kahi mea kanu me ka ʻole o ka mauʻu he mea koʻikoʻi no nā mea kanu e hoʻonui i ka hiki ke hoʻohua.Ma hope o kēia wā koʻikoʻi, pono nā mea kanu i ka pale ʻana i ka lūlū hua.Hiki i nā mahiʻai ke hana i kēia ma ka hoʻokuʻu ʻana i nā ʻanoʻano e ulu a pepehi iā lākou, a i ʻole hiki iā lākou ke pale i ka ulu ʻana a kali i ka make ʻana o nā hua a i ʻole e ʻai ʻia e nā holoholona ʻai hua.
ʻO kekahi ʻano hana ʻo ia ka hoʻohana ʻana i ka wela i hana ʻia e ka lā e hoʻomalu i nā mea ʻino i lawe ʻia e ka lepo.Hoʻokō ʻia kēia ma ka uhi ʻana i ka lepo me kahi tarp plastik maʻemaʻe i nā kau wela ke ʻike ʻia ka lepo i ka lā pololei a hiki i ʻeono pule.Hoʻomaʻamaʻa ka tarp plastik i ka papa luna o ka lepo 12 a 18 ʻīniha ka mānoanoa a pepehi i nā ʻano mea ʻino like ʻole me ka mauʻu, nā mea kanu pathogens, nā nematodes a me nā inike.
Hiki i ka insolation lepo ke hoʻomaikaʻi i ke olakino o ka lepo ma o ka wikiwiki ʻana i ka decomposition o nā mea organik a me ka hoʻonui ʻana i ka loaʻa ʻana o ka nitrogen a me nā meaʻai ʻē aʻe i ka ulu ʻana i nā mea kanu, a me ka hoʻololi pono ʻana i nā kaiāulu microbial lepo (bacteria a me nā fungi e hoʻopilikia i ke olakino o ka lepo a hope loa i ke olakino mea kanu) .
ʻO ka disinsection lepo anaerobic kahi mea ʻokoʻa ʻole kemika i ka hoʻohana ʻana i nā fumigants a hiki ke hoʻohana ʻia e hoʻomalu i kahi ākea o nā pathogens a me nā nematodes.He ʻekolu ʻanuʻu kēia e pili ana i ka hoʻohui ʻana i kahi kumu kalapona i ka lepo e hāʻawi ai i nā meaʻai i nā microbes lepo pono.Hoʻopili ʻia ka lepo i ka saturation a uhi ʻia me ka mulch plastic no kekahi mau pule.I ka wā deworming, pau ka oxygen i loko o ka lepo a make nā mea ʻawaʻawa i nā pathogens e lawe ʻia i ka lepo.
ʻO ka hoʻohana ʻana i nā mea kanu uhi i ka hoʻomaka ʻana o ke kau e hoʻopau i ka mauʻu hiki ke kōkua, akā ʻo ka pepehi ʻana ke kī, wahi a Jeff Zender, ka luna o ka papahana o Clemson no ka mahiʻai hoʻomau.
"ʻAʻole kanu nā mea kanu i nā mea kanu uhi ma muli o nā pilikia hoʻokele, me ka manawa kūpono e kanu ai i nā mea kanu uhi no ka biomass maikaʻi loa," wahi a Zender.“Inā ʻaʻole ʻoe kanu i ka manawa kūpono, ʻaʻole lawa ka biomass iā ʻoe, no laila ke ʻōwili ʻoe, ʻaʻole ia e ʻoi aku ka maikaʻi o ke kāohi ʻana i ka mauʻu.ʻO ka manawa ka mea nui. "
ʻO nā mea kanu uhi kūleʻa loa, ʻo ia ka crimson clover, winter rye, winter barley, spring barley, spring oats, buckwheat, millet, hemp, black oats, vetch, peas and winter wheat.
Nui nā mulches hoʻopau weed ma ka mākeke i kēia lā.No ka ʻike e pili ana i ka hoʻomalu ʻana i ka mauʻu ma ke kanu ʻana a me ka mulching, e ʻike iā Clemson Home and Garden Information Center 1253 a/a i ʻole HGIC 1604.
Ke ʻimi nei ʻo Cutulle a me nā mea ʻē aʻe ma Clemson Coastal REC, a me nā mea noiʻi ma ka mahiʻai organik haumāna haumāna o Clemson, i nā hoʻolālā hoʻokele weed ʻē aʻe, me ka hoʻohana ʻana i ka nitrogen wai e hoʻokuʻu i nā mauʻu ma mua o ka pepehi ʻana iā lākou a me ka ʻōwili ʻana i nā mea kanu me ka roller.Hoʻonohonoho ʻia ka hoʻomalu weed haʻahaʻa wela.
"Pono ka poʻe mahiʻai e hoʻomaopopo i ka mauʻu - ka ʻike, ka biology, etc.
Hiki i nā mahiʻai a me nā māla ke ʻike i ka mauʻu me ka hoʻohana ʻana i ka Clemson Weed ID a me ka pūnaewele Biology i hana ʻia e ke kākoʻo lab Coastal REC ʻo Marcellus Washington.
ʻO Clemson News ke kumu o nā moʻolelo a me nā nūhou e pili ana i ka hana hou, ka noiʻi a me ka holomua o ka ʻohana Clemson.
