Ngokuqhutshwa isu likazwelonke "lokulwela ukufinyelela inani eliphakeme lokukhishwa kwe-carbon dioxide ngo-2030 nokulwela ukuzuza ukungathathi hlangothi kwe-carbon ngo-2060", i-green and low-carbon ibe umgomo wokuthuthukiswa kwazo zonke izigaba zokuphila. Umgomo wekhabhoni embaxambili uqhuba izindawo ezintsha zemboni yotshani enezinga lezigidigidi eziyi-100 (ukuchotshozwa kotshani nokubuyela emishinini yasensimini, imishini ye-biomass pellet).

Utshani bezitshalo olwake lwathathwa njengodoti wezolimo, ngesibusiso sobuchwepheshe bezolimo, hlobo luni lomphumela omlingo owenzekile ekuguquleni indawo yokulima ukusuka emthonjeni wekhabhoni kuya kusinki wekhabhoni. "Izinguquko eziyishumi nambili".

Umgomo "we-Dual carbon" uqhuba ukusetshenziswa okuphelele kotshani emakethe yezinga lezigidigidi eziyi-100

Ngaphansi komgomo “wekhabhoni ekabili”, ukuthuthukiswa kokusetshenziswa okuphelele kotshani kungashiwo ukuthi kuyachuma. Ngokwesibikezelo se-Prospective Industry Research Institute, ngokuthuthuka okuqhubekayo kwezinga lokusetshenziswa kokulahlwa kwemfucuza yotshani ezweni lami kanye nokuthuthuka okuqhubekayo kobuchwepheshe, ubukhulu bemakethe bemboni yokuhlanza imfucuza yotshani buzogcina inkambiso yokukhula okuqhubekayo esikhathini esizayo. Kulindeleke ukuthi ngo-2026, yonke imboni izokhula Usayizi wemakethe uzofinyelela ku-347.5 billion yuan.

Eminyakeni yakamuva, iDolobha laseQingdao libambelele emqondweni "wokuqeda okuthathu" kokulungiswa komhlaba wonke, ukusetshenziswa okugcwele, nokuguqulwa okuphelele. Iqhubekile ihlola ubuchwepheshe obuphelele bokusetshenziswa kotshani bezitshalo obufana nomanyolo, okuphakelayo, uphethiloli, izinto eziyisisekelo, nezinto ezingavuthiwe, futhi kancane kancane yakha ifomu elingaphindaphindwa. Imodeli yemboni, yandisa indlela yokusebenzisa utshani ukuthuthukisa imboni yabalimi abacebile.

Imodeli entsha “yomjikelezo wokutshala nokuzalanisa” inweba indlela yokuba abalimi bakhulise imali engenayo

I-Qingdao Holstein Dairy Cattle Breeding Co., Ltd., enezinga elikhulu lokuzalanisa eLaixi City, njengendawo esekela ipulazi, inkampani idlulisele cishe amahektha ayi-1,000 amasimu okuhlola ukuze kutshalwe ukolweni, ummbila nezinye izitshalo. Lezi ziqu zezitshalo zingenye yemithombo ebalulekile yokudla kwezinkomo zobisi.

Izinhlanga zihlanganiswa ngaphandle kwensimu bese ziguqulwa zibe ukudla kwenkomo yobisi ngenqubo yokuvutshelwa. Indle yesisele ekhiqizwa izinkomo zobisi izongena ohlelweni lokujikeleza kwezolimo. Ngemva kokuhlukana koketshezi oluqinile, uketshezi lungena echibini le-oxidation ukuze luvutshelwe futhi lubole, futhi ukunqwabelana okuqinile kuyavutshelwa. Ngemva kokungena esitshalweni sokucubungula umanyolo, ekugcineni uzosetshenziswa njengomanyolo wemvelo wokunisela endaweni yokutshala. Umjikelezo onjalo womjikelezo awugcini nje ngokuvikela imvelo, kodwa futhi unciphisa izindleko zokukhiqiza, futhi uqaphela intuthuko eluhlaza nokusimeme kwezolimo.

UZhao Lixin, umqondisi we-Institute of Agricultural Environment and Sustainable Development of the Chinese Academy of Agricultural Sciences, uthe enye yezindlela zokufinyelela isiqongo sekhabhoni kanye nokungathathi hlangothi kwekhabhoni ezindaweni zezwe zami zezolimo nezasemaphandleni ukuthuthukisa izinga lomhlabathi nokwandisa ikhono lamapulazi nezindawo ezinotshani lokudla ikhabhoni nokwandisa usinki. Kuhlanganisa ukulima ukulima, ukubuyisela utshani ensimini, ukufakwa kukamanyolo wemvelo, ukutshala utshani bokwenziwa, kanye nokulingana kwefolishi nemfuyo, ukuthuthukisa izinto eziphilayo zasemapulazini nasezindaweni ezinotshani kungakhuphula ikhono lokumuncwa kwegesi ebamba ukushisa kanye nokulungiswa kwe-carbon dioxide, nokudlulisa indawo yokulima isuka emthonjeni wekhabhoni iye kusinki yesikhutha. Ngokwezilinganiso zochwepheshe, ngokwezidingo zamanje zokulinganisa zamazwe ngamazwe, ngaphandle kokumuncwa kwe-carbon dioxide izitshalo, ukudliwa kwekhabhoni endaweni yokulima kanye nenhlabathi enotshani ezweni lami kungamathani ayizigidi eziyi-1.2 nezingu-49 zesikhutha, ngokulandelana.

U-Li Tuanwen, inhloko ye-Qingdao Jiaozhou Yufeng Agricultural Materials Co., Ltd., uthe ngokuthembela esidingweni se-silage embonini yezilwane zasemanzini yasendaweni yase-Qingdao, ngaphezu kwebhizinisi lokuqala lezinto zezolimo, ngo-2019 baqala ukuguqula nokuzama ukukhulisa amaphrojekthi ezolimo aluhlaza ngokuhlinzeka ngezinsizakalo zenhlalo. Njengoba ihileleke emkhakheni wokucubungula nokucubungula nokusetshenziswa kotshani, “uma sithatha isilaji njengesibonelo, inkomo idinga amathani angaphezu kuka-10 ngonyaka, futhi ipulazi lezinkomo eliphakathi kufanele lithenge amathani ayinkulungwane eyodwa kuya kwezimbili ngesikhathi esisodwa.” U-Li Tuanwen uthe, ukwanda kwamanje kwaminyaka yonke kwe-silage yotshani Cishe u-30%, wonke asetshenziswa amapulazi ezinkomo endawo. Ngonyaka odlule, imali yokuthengisa yaleli bhizinisi iyodwa ifinyelele cishe ama-yuan ayizigidi ezingu-3, ​​futhi amathemba asemahle.

Ngakho-ke, bethule iphrojekthi entsha kamanyolo ukuze kusetshenziswe utshani ngokuphelele kulo nyaka, benethemba lokuqhubeka nokulungisa ukwakheka kwebhizinisi labo eliyinhloko, okuhloswe ngalo ukuqondisa kwezolimo eziluhlaza kanye nekhabhoni ephansi, nokuhlanganisa nohlelo lwezimboni lwezolimo olusezingeni eliphezulu.

Umshini we-biomass pellet usheshisa ukusetshenziswa okuphelele kwezisetshenziswa zotshani, uqaphela ukuthengiswa kanye nokusetshenziswa kwezinsiza zotshani, futhi ubaluleke kakhulu ekongeni amandla, ukwehlisa ukungcoliswa komhlaba, ukukhulisa imali engenayo yabalimi, kanye nokusheshisa ukwakhiwa komphakathi owonga izinsiza nohambisana nemvelo.
