摘　　要：[目的]了解吉林省梨树主产区果园土壤养分状况。[方法]对52个有代表性的梨园土壤p H和矿质养分含量进行调查分析。[结果]5个县市梨园土壤的p H范围分别为5.60~6.45、4.93~6.75、5.51~6.46、4.55~6.20、5.16~6.47,有机质含量范围分别为1.58%~3.38%、1.62%~2.68%、1.79%~5.47%、1.73%~3.14%、2.03%~3.74%,碱解氮、有效磷、速效钾含量范围分别为80.85~102.01、42.33~101.55、150.19~313.26 mg/kg,交换钙和交换镁、有效锌含量较高,有效铜、有效铁、有效锰含量普遍较适宜。[结论]吉林省部分县市土壤酸化较严重,有机质含量较适宜,能保证梨树正常生长,同时应控制钙、镁、锌肥的使用。[Objective] The research aimed to study soil nutrient status in present main producing areas of Jilin. [Method]p H and mineral nutrient contents of 52 representative soil were investigated and analyzed. [Result] The range of p H in pear orchards of five counties was 5. 60-6. 45,4. 93- 6. 75,5. 51- 6. 46,4. 55- 6. 20 and 5. 16- 6. 47. The range of organic matter content was 1. 58%- 3. 38%,1. 62%- 2. 68%,1. 79%- 5. 47%,1. 73%- 3. 14% and 2. 03- 3. 74%. The range of N,P,K content was 80. 85- 102. 01,42. 33- 101. 55 and 150. 19-313. 26,respectively. The exchangeable contents of Ca,Mg and Zn were effectively high. Available Cu,Fe and Mn content were generally appropriate. [Conclusion] Organic matter content is more appropriate,but soil acidification occurred in some counties. And the application of calcium,magnesium and zinc fertilizer shall be controlled.
