法库县无公害项目区土壤养分状况评价与施肥建议

Evaluation of Soil Nutritional Status and Fertilization Recommendations in Pollution-free Agricultural Project Area of Faku County

为充分了解法库县项目区的土壤肥力状况,对全县3866.7hm2无公害生产基地的土壤进行采样,并分析其营养状况。统计结果显示:项目区土壤有效氮、速效磷含量大部分偏高,有机质含量大多处于中等偏高水平,速效钾含量中等偏高;土壤养分变化较大,含量分布不平衡,尤其是速效磷、速效钾和有机质表现得尤为明显。

In order to fully understand the soil fertility status of the project area,combined with biological characteristics of crops,pollution-free production base of 5.8 million mu of soil has been sampled and analyzed on their nutritional status,including effective soil nitrogen,available phosphorus,potassium and organic matter. The experiment findings show that there is a large content of available nitrogen and available phosphorus in the tested soil,most of the organic matter and available potassium are at a medium-high level,there is a major change in the composition of the soil contents,and their distribution is uneven,especially in the case of available phosphorus,potassium and organic matter.
