Abstract
[Objective]The objective is to evaluate soil nutrient situation.[Method]Eight agrochemical indexes of top layer soil content analysis of 499 samples were analyzed by conventional method.[Result]Top layer soil nutrient was as follows in Guide County: organic matter 19.71 g/kg,total nitrogen 1.54 g/kg, total phosphorus 1.70 g/kg, available nitrogen 111 mg/kg, effective phosphorus 41 mg/kg, available potassium 249 mg/kg, slowly available potassium 1 029 mg/kg,pH 7.97.On the whole,nutrient level of available nitrogen,available potassium, and slowly available potassium of Guide County soil was high.Content of effective phosphorus, organic matter was at medium level compared with abundance and deficiency index.[Conclusion]The research can offer based data for the cultivated land fertility evaluation and soil testing and fertilizer recommendation.关键词
