摘　　要：连续2年对北京郊区桃园进行覆草研究。结果表明:果园覆草土壤有机质含量增加41.46%,0～5cm土层土壤温度降低3.2℃;单果增重10.89%,果实产量增加8.93%,可溶性固形物含量增加2.00%,硬度增加10.53%,中、长枝比例提高13.06%,利于果树提高产量。果园覆草是桃树高效生产中的首选模式。A continuous 2 years research of grass cover was conducted in peach orchard in Beijing suburb. The results showed that grass cover increased the soil organic substances by 41.46%, reduced the soil temperature by 3.2 ℃ ,increased average fruit weight by 10.89 % ,fruit production by 8.93%, soluble solid content by 2.00 %, flesh firmness by 10.53 %, middle and long branch by 13.06%. Grass cover might be the first mode effective in the production of peach.
