摘要
针对皖南酸性红黄壤的酸和瘠特点 ,采用田间试验方法研究了白云石对皖南酸性红黄壤的改土效果。结果表明 :皖南酸性红黄壤上施用白云石能改善小麦生长发育状况 ,显著提高小麦的产量。白云石施用量以 110 0～ 16 0 0kg/hm2
Focusing on the soils with acid condition and low fertility in southern Anhui, the field trial was conducted in order to study the effect of the dolomite application on the wheat growth. The results indicated that the dolomite could promote wheat growth, and increase yield significantly. The highest wheat yield and the best benefit could produce as the amount of dolomite application was 1100-1600kg/hm 2.
