Chemisation imfuyo: amatyala njengokwamkelekileyo ngokungenabulungisa isicelo yayo

Imichiza kwezolimo - le yenye yezona ndlela isebenzayo ukwenza kube ngakumbi iindleko-olusebenzayo. Ukusetyenziswa kwemichiza yenza kube lula ngeendleko liphantsi ukufezekisa iziphumo eziphakamileyo, nokuba ukulinywa kwezityalo ezahlukeneyo okanye imveliso imfuyo.

Inkolelo yokuba ukusetyenziswa kweekhemikhali imfuyo - kukusetyenziswa hormone, amachiza okanye machiza yingozi ukwanda ngokukhawuleza ubunzima inyama, olungachanekanga. isilwanyana ikakhulu chemicalisation ijolise izifo ekuthinteleni kunye nezondlo isilwanyana. Ngoko ke, inkoliso ongeziweyo ukutya lijolise ekwandiseni icandelo nezo ifidi - oko kukuthi, ukuba zongezwa okanye kuhlelwe iiproteni, okanye izakhiwo asidi acid. components ezifanayo afumaneka ifomula usana ezininzi okanye iimveliso ukutya lwezonyango, ukuze sikwazi ukuthetha ngokuzithemba malunga nokhuseleko lwabo. ukusebenzisa yabo kwandisa ngokubalulekileyo nokukhawulezisa ukukhula ubunzima inyama, ukunciphisa kakhulu iindleko ukutya, ngoko akukho nje ngokupheleleyo kufanelekile, kodwa inqweneleka kakhulu.

Kwakhona kubalulekile kakhulu ukuya kushishino ngokutya okunesondlo ezifana wefula nagwele. Ngokuba iinkomo lwemfuyo ukusetyenziswa kwazo kubaluleke kakhulu: usetyenziso ithani Igwele ivumela ukwandisa imveliso yehagu ku buziikhilogram ezimakhulu asixhenxe, nokuba inyama yenkukhu - up to iitoni ezimbini, kwaye ke akukho ezinobungozi kwimpilo yomnye umntu, kodwa ibe inani izondlo ezibalulekileyo .

Ukongeza ukwandisa ixabiso lesondlo ukutya kunye nemfuyo nokusetyenziswa kwemichiza ingabhekiswa ukhuseleko lwabo ngexesha ebusika. Oku kunokuba nje kuphela izinto kusetyenziswa kwisigcinakaliso ukuze kungonakali efula, kodwa nazo zonke iintlobo iindlela ukhuseleko ngokwasemzimbeni evela iimeko zangaphandle, umzekelo, iifilim okanye kwizikhongozeli ezahlukeneyo izinto polymeric.

Uhlobo elandelayo imichiza esetyenziswa lulimo izilwanyana - ngamachiza zonyango lwezilwanyana kwaye kuthetha ukuba ijongane usulelo. Xa uluhlu kwazo kuquka kuphela amachiza ekujongwe ukuba ukunyanga izifo ezikhoyo, okanye ezisetyenziswa zokuthintela zazo (umz, ukuthintela helminthiasis), kodwa kwakhona zonke iintlobo izibulali. Oku kuquka umlinganiselo ethandwayo ngakumbi nokuthintelwa kwezifo zemfuyo, ezifana nokusebenzisa imithi, leyo ngaxeshanye ukukhuthaza ukukhula izilwanyana nokuqinisekisa ukhuseleko olukhulu kwenyama. Kakade ke, ngaxa ethile kunokuba luncedo, kodwa ekugqibeleni kube buhlungu kuphela imfuyo, kuba ukusebenzisa njalo-ntsholongwane kukhokelela kukuba iintsholongwane ukumelana ezininzi kubo, kwaye amathuba nezifo ezinzulu uya kwandisa kuphela, yaye indlela yokulwa ngayo rhoqo limited. Ukongeza, ezi izinto singene imveliso yokugqibela, nto leyo kakhulu ayikhuselekanga ukutyiwa ngabantu. Okufanayo - hormone kwi 80s lwekhulu yokugqibela, waqalisa ukusetyenziswa kwazo kakhulu makanyebeleze ngaphezu abaphengululi abaninzi badla ukucacisa ukukhawulezisa ngequbuliso kule inani labantu okuye kwenzeka kule 80-90s - mhlawumbi ngaphambi okanye emva kokuba ubude avareji abantu abatsha akuzange kube enkulu kangaka.

Emva koko waqalisa bendelisele iingcambu yonke kunye nebiotechnology lulimo yezilwanyana, kodwa ngenxa Uphononongo lwakutsha nje ukhuseleko usebenzisa iimveliso transgenic ekondlweni yabantu ngabanye izazinzulu Bambuza ke biotechnology isicelo ngononophelo. Nangona kunjalo, ukusetyenziswa iikhemikhali lulimo izilwanyana kwi ngokusetyenziswa ngokugqithisileyo kwaye ezingafanelekanga beziyobisi kungaba umonakalo bokuba, kodwa ngeengozi yeMfuzo ayaziwa, ngaphezu koko, abaninzi imibuzo.
