于2010年测定了杭州市桐庐县514个油菜地土壤肥力。结果表明，桐庐县油菜地土壤的有机质含量为16.8～30.0 g?kg-1，平均23.3 g?kg-1，土壤全氮含量为0.93～2.34 g?kg-1，平均1.73 g?kg-1；碱解氮、速效磷和速效钾含量分别为（18.7～268.0），（0.6～133.1）和（1～238）mg?kg-1，平均含量分别为82.7，15.7和63.6 mg?kg-1。桐庐县油菜地土壤碱解氮和速效钾缺乏面积分别占总面积的68.1％和69.3％，速效磷缺乏面积占总面积的46.7％。油菜产量与土壤碱解氮含量极显著正相关（r＝0.851**，n＝15），与速效磷含量显著正相关（r＝0.553*，n＝15），而与土壤有机质、全氮和速效钾含量无显著相关性。

Soil fertility of 514 soil samples in the rapeseed production district in Tonglu County was investigated in 2010.The results showed that the contents of organic matter ranged from 16.9 to 30.0 g?kg-1 , with an average of 23.3 g?kg-1 .The contents of total N were 0.93~2.34 g?kg-1 , and the average was 1.73 g?kg-1 .The contents of available N, P and K were 18.7~268.0 mg?kg-1 , 0.6~133.1 mg?kg-1 and 1~238 mg?kg-1 , respectively, with the average of 82.7, 15.7 and 63.6 mg?kg-1 , respectively.Based on the available N, P and K content, nutrient deficiency area accounted for 68.1%, 46.7%, and 69.3%, respectively, of the total rapeseed fields in the present study.Rapeseed yield was significantly correlated with soil available N contents (r=0.851**, n=15) and soil available P (r=0.553*, n=15).But no significant relationship was found within the contents of organic matter , total N and available K with rapeseed yield .
