海南省临高县蔗区土壤主要养分状况分析研究与对策

Practices and Analytic Study of the Main Nutrient Conditions of Soil in the Sugarcane Production Area of Lin'gao in Hainan

对临高县蔗区土壤养分状况进行了分析研究,测定了土壤有机质、全氮、全磷、全钾、碱解氮、有效磷、速效钾、pH值、交换性钙镁等指标。经研究,发现了该蔗区土壤含氮水平过高,缺磷、钾,交换性钙镁含量超标等问题。针对存在问题,根据当地甘蔗生产实际,提出了相应对策。

The paper studied the nutrient conditions of soils in the sugarcane production area of Lin＇gao in Hainan. The indexes of organic matters, total nitrogen, total phosphorus, total potassium, alkali-hydrolyzable nitrogen, available phosphorus, available potassium, pH value, exchangeable calcium and magnesium etc. were detected. It is discovered that Lin＇gao was rich in nitrogen, deficient in phosphorus and potassium, excessive in exchangeable calcium and magnesium, etc. Countermeasures were presented accordingly.
