Mankhwala apakati

Mankhwala ophera tizilombo ndi njira yofunika kwambiri popangira ulimi, yomwe imagwira ntchito yofunika kwambiri pakuwongolera matenda, tizirombo ndi udzu, kukhazikika komanso kukonza zokolola.

Ngakhale zimakhudzidwa ndi mtengo wazinthu zaulimi, malo obzala, nyengo, kuwerengera ndi zinthu zina, kugulitsa mankhwala ophera tizilombo kudzawonetsa kusinthasintha kwapachaka chaka ndi chaka, koma kufunikira kukadali kolimba.

Malinga ndi kafukufuku wochokera ku National Bureau of Statistics, kupanga mankhwala ophera tizilombo padziko lonse lapansi kwawonetsa kuchepa kuyambira 2017.
Mu 2017, zotsatira za mankhwala ophera tizilombo zidatsika mpaka matani 2.941 miliyoni, koma mu 2018 zidagwera matani 2.083 miliyoni. Mu 2019, kutulutsa kwa mankhwala ophera tizilombo kunasiya kutsika ndikukwera mpaka matani 2.2539 miliyoni, kukwera ndi 1.4 peresenti pachaka.

M'zaka zaposachedwa, ndalama zogulitsa mankhwala ku China zakhala zikuchulukirachulukira.
Mu 2018, chifukwa cha chitukuko cha mankhwala ophera tizilombo komanso kukwera kwamitengo yazinthu, komanso kukwera kwa kufunikira kwa mankhwala ophera tizilombo mu mbewu zandalama monga thonje ndi zomangamanga, ndalama zogulitsa pamsika zidali pafupifupi 329 biliyoni ya yuan.
Akuti kukula kwa msika waulimi waku China kukuyembekezeka kukwera mu 2020.

Mankhwala ophera tizilombo osiyanasiyana amafunikira mitundu yosiyanasiyana yapakati popanga.
Chopangidwa pokonza zopangira zaulimi ndi njira yapakatikati yomwe imaphatikiza zinthu ziwiri kapena kupitilira apo.
Mu mankhwala amatha kumveka ngati synergist, amadziwikanso kuti organic intermediates.
Poyambirira amatanthauza kugwiritsa ntchito phula la malasha kapena mafuta amafuta ngati zida zopangira zokometsera, utoto, utomoni, mankhwala, mapulasitiki, ma accelerator amphira ndi zinthu zina zama mankhwala, opangidwa popanga zinthu zapakatikati.

The kaphatikizidwe wa intermediates zambiri ikuchitika mu riyakitala, ndi kwaiye intermediates anapatukana ndi kuyeretsedwa, kawirikawiri ndi luso m'zigawo.
Mankhwala ophera tizilombo ndi chloroform m'zigawo ndi mankhwala ogwira ntchito wamba unit ntchito, chikhalidwe ntchito ndondomeko zambiri utenga distillation ndime, mtundu wa ntchito ndondomeko zovuta, otsika m'zigawo bwino, kugwiritsa ntchito mphamvu ndi kwakukulu, choncho ndi kuzama kwa magawano pakati pa anthu ntchito ndi Kupita patsogolo kwaukadaulo wopanga, mabizinesi ambiri amayamba kukweza zaukadaulo, ndikusankha njira yogwira ntchito.
