摘 要: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 *** addition,applying polyacrylamide can also increase corn yield by 540 5kg·ha -1 ,and net income by 240 5ha.
