Abstract:

In order to provide the data foundation for the demonstration of the straw stalk sandy soil ameliorating materials, the pot experiments used to inquire into the interacted function of the straw stalk and Bentonite and PAM (Polyacrylamide) were designed. The results indicate that it obviously raises the content of the soil cation exchange capacity and the contents of the soil organic matter and humus. The best formula respectively improves the content of the soil cation exchange capacity and the contents of the soil organic matter and humus by 36%, 28%, 25% compared with the contrast in 60 days.
