Xyoo 2023, kev lag luam phosphorus daj hauv tebchaws tau poob qis ua ntej thiab tom qab ntawd nce siab, thiab tus nqi ntawm qhov chaw tau siab tshaj plaws hauv tsib xyoos dhau los, nrog rau tus nqi nruab nrab ntawm 25,158 yuan / ton txij lub Ib Hlis mus txog rau lub Cuaj Hli, poob qis 25.31% piv rau xyoo tas los (33,682 yuan / ton); Qhov qis tshaj plaws ntawm lub xyoo yog 18,500 yuan / ton thaum nruab nrab Lub Tsib Hlis, thiab qhov siab tshaj plaws yog 31,500 yuan / ton thaum ntxov Lub Ib Hlis.

Txij lub Ib Hlis mus txog rau lub Cuaj Hlis, tus nqi lag luam ntawm cov phosphorus daj yog tsav los ntawm kev hloov pauv tas mus li ntawm cov nqi logic thiab cov khoom siv thiab kev thov logic. Piv nrog rau lub sijhawm tib yam hauv xyoo 2022, tus nqi thiab kev thov ntawm cov phosphorus daj yog ob qho tib si tsis zoo thiab tsis zoo, tus nqi ntawm cov phosphorus daj tau poob qis, thiab cov nyiaj tau los tau txo qis heev. Tshwj xeeb, tus nqi ntawm cov phosphorus daj hauv thawj ib nrab ntawm lub xyoo txij lub Ib Hlis mus txog nruab nrab Lub Tsib Hlis feem ntau poob qis; Hauv thawj ib nrab ntawm lub xyoo, kev lag luam hauv tsev neeg tau poob siab, qee lub tuam txhab downstream muaj cov khoom muag ntau, cov tuam txhab lag luam tsis zoo, kev txaus siab rau kev yuav khoom phosphorus daj tsis siab, thiab kev rov qab los ntawm cov tuam txhab phosphorus daj yog sai dua li kev rov qab los ntawm kev thov, muaj lub xeev ntawm kev muab khoom ntau dhau, cov tuam txhab tsim cov phosphorus daj raug kev nyuaj siab, thiab cov khoom lag luam hauv kev lag luam maj mam nce. Cov khoom siv raw phosphate ore, coke, graphite electrodes thiab lwm yam nqi poob qis, nkag mus rau lub sijhawm ntub tom qab tus nqi hluav taws xob txiav, tus nqi ntawm kev sib tham tsis zoo, ua rau tus nqi phosphorus daj tseem tsom mus rau qis qis, cov nyiaj tau los ntawm kev lag luam txo qis heev. Thaum kawg ntawm lub Tsib Hlis, tus nqi tau poob qis thiab pib maj mam rov qab los, feem ntau yog vim tus nqi ntawm cov phosphorus daj tseem pheej poob qis, qee lub tuam txhab tus nqi nce siab, xaiv kom tsis txhob tsim khoom thiab txo kev tsim khoom, kev tsim cov phosphorus daj tau txo qis heev, ua rau kev siv cov khoom lag luam ntawm kev lag luam phosphorus daj, thiab cov tuam txhab muaj kev ntseeg siab rau tus nqi. Sab nqi kuj tau tsis txhob poob qis thiab ruaj khov, qee cov khoom siv raw muaj qhov rov qab los, sab nqi tau nce kev txhawb nqa, qee qhov kev txiav txim siab txawv teb chaws xws li glyphosate tau nce, cov nyiaj tau los ntawm cov tuam txhab loj, cov khoom pib ua haujlwm siab, thiab qhov kev thov rau kev lag luam phosphorus daj ruaj khov, ua rau kev lag luam phosphorus daj nyob rau hauv qhov xwm txheej nruj ntawm kev muab khoom, thiab tus nqi tau tig mus txuas ntxiv nce. Nrog rau kev nce qeeb ntawm cov tuam txhab, cov khoom lag luam phosphorus daj txuas ntxiv mus sib sau ua ke, kev muab khoom lag luam phosphorus daj tam sim no txaus, kev thov qis qis, kev muab khoom ntau dhau ua rau tus nqi siab nyuaj rau tswj, nws nyuaj rau nce siab heev hauv lub sijhawm luv luv.

Cov laj thawj tseem ceeb rau qhov sib txawv ntawm kev ua lag luam phosphorus daj txij lub Ib Hlis mus txog rau lub Cuaj Hli yog: qhov kev ua si ntau zaus ntawm sab saud thiab sab hauv qab los ntawm kev tsis sib npaug ntawm kev muab khoom thiab kev thov, tus nqi raw khoom nce siab, thiab kev hloov pauv hauv txoj cai.

Nws xav tias tus nqi ntawm kev ua lag luam phosphorus daj hauv lub quarter thib plaub yuav txuas ntxiv mus hloov pauv, thiab thaum Lub Kaum Hli, cov tuam txhab phosphorus daj yuav tos thiab saib kev ua lag luam, tab sis qhov kev thov tsis muaj zog, lossis tseem muaj qhov ua tau poob qis. Kev faib hluav taws xob tom ntej hauv Yunnan tseem xav tias yuav nce ntxiv, thiab tus nqi hluav taws xob hauv lub caij qhuav yuav nce siab, thiab tus nqi yuav txhawb nqa kev ua lag luam phosphorus daj. Sab kev thov tseem tsis muaj zog, thiab cov lag luam phosphoric acid, phosphorus trichloride thiab glyphosate qis dua txias, thiab tsis muaj kev txhawb nqa zoo rau kev thov.
