| 摘 要： | 为了解沈阳市玉米主产区土壤养分状况及其与玉米产量水平之间的关系，于2004～2005年对沈阳市不同肥力水平的玉米主要产区的土壤有机质和有效磷含量及其与玉米产量水平之间的关系进行分析。结果表明，沈阳市玉米主产区土壤有机质含量总体处于中低水平，有效磷含量总体处于较高水平；玉米的产量水平与有机质和有效磷含量之间表现出了极显著的正相关关系。由此提出增施有机肥，实行有机无机肥配施以及建立适应目前农业生产需要的土壤磷素丰缺指标是发挥玉米增产潜力的必要手段。

| Abstract: | In order to explore the relationship between the status of soil nutrition and yield levels on the maize cropping land of Shenyang, the detailed survey sampling was made in 2004- 2005 in different fertility soils of maize around Shenyang , analyzing the correlation between soil organic matter, available P concentration and maize yield. Results showed that on the whole, the soil organic matter concentration was in the lower or medium level and the soil available P concentration was in higher level. It was re- vealed that the yield level of maize, soil organic matter and available P content manifest the remarkable positive correlationship . So we can conclude that it is an effective measure to exeit the maize production increasing potential with increasing manure fertilizer input, putting into practice that fertilizing the manure and chemical fertilizer and estabilishing the proper soil phosphorous criterion. |
