摘要:

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。

Abstract: 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.
