Abstract：To know the current soil nutrient status in pear orchards in Beijing area , the soil pH and min-eral nutrient in 51 typical pear orchards were investigated .The results showed that the pear orchards with soil pH value of 6.5~7.5 only occupied 56.60%.And the soil pH in other 43.40%pear orchards was too low or too high.The soil organic matter content in 54.90%pear orchards ranged from 1.00%to 2.00%, and that in 29 .41%pear orchards was less than 1 .00%.46 .16%pear orchards had lower total nitrogen content in soil . But the soil available P and K contents were relatively higher .30 .19%pear orchards had excessive soil avail-able zinc .96 .22% pear orchards had higher exchangeable calcium content .The exchangeable magnesium content in 94 .34% pear orchards was above medium level .However , the soil available iron content in 84 .91%pear orchards was too low .Therefore , adjusting the soil pH value , applying organic fertilizer incorpo-rated with nitrogen fertilizer , adding iron fertilizer and decreasing zinc fertilizer were the emphases of soil nu-trient management in future in pear orchards in Beijing .
