摘要:
通过夏玉米施加聚丙烯酰胺（PAM）的大田实验，确定了PAM的改土、增产效应。研究表明，PAM施用量为0.75～1.25 g/m2 时可使土壤容重平均下降0.068 g/cm3，团聚体总量（>0.25 mm）平均增加30.2%，同时，PAM增产效果显著，增产幅度为11.7%～18.3%。
Abstract:
After the study of adding polyacrylamide to summer maize in farmland, the effect of Polyacrylamide(PAM) on soil and yield is obvious. The result shows when the concentration of PAM is between 0.75~1.25 g/m2, the bulk density of soil can decrease at the rate of 0.068 g/cm3 and the pore degree of soil is increased. PAM can increase the amount of soil aggregate(0.25mm) at the rate of 30.2%. That is PAM has a better effect on soil improvement. PAM can also increase yield significantly at the rate of 11.7~18.3%.
