Polyacrylamide, musanganiswa unoshanduka-shanduka, wakawana mashandisirwo akakosha muminda yakasiyana-siyana. Munyaya yekuchengetwa kwehove, polyacrylamide yave chishandiso chakakosha chekuvandudza kunaka kwemvura nekusimudzira kukura kwakanaka kwehove neshrimp. Muchinyorwa chino, tinoongorora mashandisirwo akasiyana-siyana epolyacrylamide mukurima hove neshrimp, tichiratidza mabhenefiti ayo uye mipiro yayo mukuita kwekuchengetedza hove munzvimbo dzinogara kwenguva refu.
Chikamu 1: Kunzwisisa PAM nekukosha kwayo mukurima gungwa
Polyacrylamide ipolymer inonyungudika mumvura inoita colloidal suspensions. Hunhu hwayo hwemakemikari hwakasiyana hunoita kuti ive sarudzo yakanaka yekurapa mvura uye kushandiswa kwezvakatipoteredza. Mukurima hove, kuchengetedza mhando yepamusoro yemvura kwakakosha pakugara zvakanaka uye kukura kwehove neshrimp.
Chikamu 2: Kutarisirwa Kwemhando Yemvura
Polyacrylamide inoita basa rakakosha mukutarisira kunaka kwemvura mukurima hove neshrimp. Semushonga unobatanidza hove, inobvisa zvinobudirira zvidimbu zvakasungirirwa, turbidity, uye organic matter mumvura. Nekuwedzera kuchena kwemvura uye kuderedza zvinhu zvakasungirirwa, polyacrylamide inobatsira kugadzira nharaunda inobatsira hupenyu hwemumvura hune hutano.
Chikamu 3: Kudzora Zvinovaka Muviri uye Kudzivirira Maruva eAlgal
Zvinovaka muviri zvakawandisa, zvakaita senitrogen nephosphorus, zvinogona kukonzera kuumbwa kwemvura yakawanda uye kutumbuka kwealgal mu aquaculture systems. Polyacrylamide inoshanda semushonga unokwevera, ichibatsira kubvisa zvinovaka muviri zvakawandisa mumvura. Izvi zvinobatsira kudzivirira kukura kwealgal, kuchengetedza ecosystem yakaringana uye kuderedza njodzi yekupera kweoxygen.
Chikamu 4: Kushanda Nesimba Kwekudya Uye Kukurudzira Kukura
PAMinogona kushandiswawo sechikafu chinowedzera mukurima hove neshrimp. Inovandudza kugaya chikafu nekupinza chikafu, ichivandudza kushandiswa kwezvinovaka muviri uye ichikurudzira kukura. Nekuwedzera kushanda zvakanaka kwechikafu, polyacrylamide inobatsira pahutano hwese nekukura kwezvisikwa zvemumvura.
Chikamu 5: Maitiro Ekurima Mvura Anogara Mumvura
Kushandiswa kwepolyacrylamide kunoenderana nemisimboti yekurimwa kwemvura inochengetedza nharaunda. Kushandiswa kwayo kunoderedza kuvimba nemakemikari anokuvadza uye kunoderedza kukanganisa kwezvakatipoteredza kunokonzerwa nekusachena kwemvura. Pamusoro pezvo, nekuvandudza mamiriro emvura uye kukurudzira kukura kwakanaka, polyacrylamide inotsigira kubudirira kwemabasa ekurimwa kwemvura.
Chikamu 6: Kushandiswa Kwemutoro uye Mitemo
Kunyange hazvo kushandiswa kwepolyacrylamide mukupfuya hove kuchipa mabhenefiti akawanda, zvakakosha kuve nechokwadi chekuti kushandiswa kwayo kwakakodzera. Kutevedzera nhungamiro nemitemo kwakakodzera kwakakosha kudzivirira chero migumisiro yakaipa panharaunda nehupenyu hwemumvura. Kushandiswa kwakakodzera, pamwe chete nedzimwe nzira dzekutarisira kupfuya hove, kunovimbisa kugara zvakanaka kwehove, shrimp, uye kugara kwenguva refu kwenzira dzekurima.
Polyacrylamide inobuda senzira inoshanda uye inoshanda yekugadzirisa kunaka kwemvura uye kukurudzira kukura kwakanaka mukurima hove neshrimp. Mashandisirwo ayo mukutarisira kunaka kwemvura, kudzora zvinovaka muviri, uye kushanda zvakanaka kwekudya kwemhuka zvinobatsira mukuchengetedza hove dzemumvura. Nekushandisa mabhenefiti epolyacrylamide, nyanzvi dzekurima hove dzinogona kugadzira masisitimu anobudirira uye anongwarira zvakatipoteredza, zvichiita kuti zvipenyu zvemumvura zvive zvakanaka uye remangwana reindasitiri iyi.
