Poyendetsedwa ndi ndondomeko ya dziko "kuyesetsa kuti afike pachimake cha mpweya woipa wa carbon dioxide pofika chaka cha 2030 ndi kuyesetsa kukwaniritsa kusalowerera ndale kwa carbon ndi 2060", zobiriwira ndi zochepa za carbon zakhala cholinga cha chitukuko cha anthu osiyanasiyana. Cholinga cha kaboni wapawiri chimayendetsa malo atsopano opangira udzu wa 100 biliyoni (kuphwanya udzu ndikubwerera kumakina akumunda, makina a biomass pellet).

Udzu wa mbewu womwe kale unkawoneka ngati zinyalala zaulimi, kudzera m'dalitso laukadaulo waulimi, ndi mtundu wanji wamatsenga womwe wachitika pakusintha kwaminda kuchokera kugwero la kaboni kupita kukuya kwa kaboni. "Zosintha khumi ndi ziwiri".

Cholinga cha "Dual carbon" chimapangitsa kuti udzu ugwiritse ntchito bwino pamsika wa 100 biliyoni.

Pansi pa cholinga cha "dual carbon", chitukuko cha kagwiritsidwe ntchito kake ka udzu tinganene kuti chikuyenda bwino. Malinga ndi kuneneratu kwa Prospective Industry Research Institute, ndikusintha kosalekeza kwa kagwiritsidwe ntchito ka zinyalala m'dziko langa komanso kupita patsogolo kwaukadaulo, kukula kwa msika wamakampani opangira zinyalala kusungitsa kukula kwachuma. m'tsogolo. Zikuyembekezeka kuti pofika chaka cha 2026, makampani onse adzakula Kukula kwa msika kudzafika 347.5 biliyoni yuan.

M'zaka zaposachedwa, mzinda wa Qingdao watsatira lingaliro la "kumaliza katatu" kokonzanso padziko lonse lapansi, kugwiritsidwa ntchito kwathunthu, komanso kutembenuka kwathunthu. Yakhala ikuwunika mosalekeza ukadaulo wogwiritsa ntchito udzu wa mbewu monga feteleza, chakudya, mafuta, zinthu zoyambira, ndi zopangira, ndipo pang'onopang'ono idapanga mawonekedwe omwe angabwerezedwe. Makampani, kulitsa njira yogwiritsira ntchito udzu kuti atukule makampani olemera alimi.

Njira yatsopano ya "kubzala ndi kuswana" imakulitsa njira kuti alimi awonjezere ndalama

Qingdao Holstein Dairy Cattle Breeding Co., Ltd., yomwe ili ndi sikelo yayikulu kwambiri yoweta ku Laixi City, ngati malo osamalira ziweto, kampaniyo yasamutsa pafupifupi maekala 1,000 aminda yoyesera kuti ilime tirigu, chimanga ndi mbewu zina. Mapesi a mbewu awa ndi amodzi mwa magwero ofunikira a ng'ombe zamkaka.

Mapesi amamangidwa m'mitolo kuchokera m'munda ndikusandutsidwa chakudya cha ng'ombe za mkaka kudzera mu nayonso mphamvu. Chimbudzi cha silaji chopangidwa ndi ng'ombe zamkaka chidzalowa m'dongosolo laulimi wobiriwira. Pambuyo pa kupatukana kwamadzi olimba, madziwo amalowa mu dziwe la okosijeni kuti afufuze ndikuwola, ndipo kusonkhanitsa kolimba kumafufuzidwa. Mukalowa m'fakitale yopangira feteleza, pamapeto pake idzagwiritsidwa ntchito ngati feteleza wa organic wothirira pamalo obzala. Kuzungulira kotereku sikumangoteteza chilengedwe, komanso kumachepetsa ndalama zopangira, ndikuzindikira chitukuko chobiriwira komanso chokhazikika chaulimi.

Zhao Lixin, mkulu wa Institute of Agricultural Environment and Sustainable Development of the Chinese Academy of Agricultural Sciences, ananena kuti njira imodzi yopezera nsonga ya mpweya ndi kusaloŵerera m’malo a carbon m’madera a zaulimi ndi akumidzi m’dziko langa ndi kukonza nthaka yabwino ndi kuonjezera luso. wa minda ndi udzu kuti atenge kaboni ndikuwonjezera masinki. Kuphatikizira kulima, kubweza udzu kumunda, kugwiritsa ntchito feteleza wachilengedwe, kubzala udzu wopangira, komanso kudyetsa ziweto, kuwongolera minda yaudzu ndi udzu kumatha kukulitsa luso la kuyamwa kwa mpweya wowonjezera kutentha ndi kukonza mpweya wa carbon dioxide, ndikusamutsa minda kuchokera gwero la carbon ku sink ya carbon. Malinga ndi kuyerekezera kwa akatswiri, malinga ndi zomwe zikuchitika padziko lonse lapansi muyeso, kupatula kuyamwa kwa carbon dioxide ndi zomera, kuchotsedwa kwa mpweya wa minda ndi udzu m'dziko langa ndi 1.2 ndi matani 49 miliyoni a carbon dioxide, motero.

Li Tuanwen, wamkulu wa Qingdao Jiaozhou Yufeng Agricultural Materials Co., Ltd., adati kudalira kufunikira kwa silage m'makampani am'madzi am'deralo a Qingdao, kuwonjezera pa bizinesi yoyambirira yaulimi, mu 2019 adayamba kusintha ndikuyesera kukulitsa zobiriwira. ntchito zaulimi popereka chithandizo cha anthu. Pochita nawo ntchito yokonza ndi kukonza ndi kugwiritsiridwa ntchito kwa udzu, “mwachitsanzo, ng’ombe imafunika matani oposa 10 pachaka, ndipo famu ya ng’ombe yapakatikati imayenera kuitanitsa matani chikwi chimodzi kapena ziŵiri panthawi imodzi.” Li Tuanwen adati, kuwonjezeka kwapachaka kwa silage ya udzu Pafupifupi 30%, zonsezi zimagwiritsidwa ntchito ndi minda ya ng'ombe. Chaka chatha, ndalama zogulitsa za bizinesi iyi yokha zidafika pafupifupi 3 miliyoni yuan, ndipo ziyembekezo zikadali zabwino.

Chifukwa chake, akhazikitsa pulojekiti yatsopano ya feteleza yogwiritsa ntchito udzu mokwanira chaka chino, akuyembekeza kuti asintha mosalekeza momwe bizinesi yawo yayikulu ikuyendera, potsata njira yaulimi wobiriwira komanso wopanda mpweya wa kaboni, ndikuphatikiza munjira zamafakitale apamwamba kwambiri. .

Makina a biomass pellet amafulumizitsa kugwiritsidwa ntchito mokwanira kwa udzu, amazindikira kugulitsa ndi kugwiritsa ntchito udzu, ndipo ndiwofunikira kwambiri pakupulumutsa mphamvu, kuchepetsa kuipitsidwa, kuchulukitsa ndalama za alimi, ndikufulumizitsa ntchito yomanga njira yopulumutsira zinthu ndi chilengedwe- anthu ochezeka.
