Abstract

Abstract: Field plots observations indicate that applying polyacrylamide to soil can reduce surface runoff by 18.4%～46.8%,decrease soil erosion by 13%～55%,and increase soil organic matter,alkali-hydrolyzable nitrogen,available phosphate,available potassium in different degrees compared with not application.In addition,applying polyacrylamide can also increase corn yield by 540.5kg·ha^-1,and net income by 240.5ha.

Key words: lysosome, pollution, biomarker, lysosomal membrane stability, neutral red retention time.
