Abstract
On the carbonate meadow soil contains sand in Liurao area, 3 trial treament such as routine chemical fertilizer, 50% straws return to field plus routine chemical fertilizer, 100% straws return to field plus routine chemical fertilizer were designed to study the effects of straws return to field on growth, development and yield of maize. The results showed that compared to the routine chemical fertilizer, straws return to field could not lessen the resistance of lodging and chlorophy1l content, advanced LAI, and 50% straws return to field increased the yield of maize. There were insignificant difference between 100% straws return to field and the routine chemical fertilizer.
