采用野外采样、室内化验分析方法,研究了海南省三亚市甘肃敦煌种业杂交玉米繁殖基地土壤养分分布特征。结果表明:该基地土壤呈酸性反应,建议施用生石灰将土壤p H值调节到微酸性;土壤有机质、碱解氮和速效钾普遍缺乏,速效磷中等;交换性钙和交换性镁含量中等,有效铁、锰、铜、锌含量丰富。
Field sampling and laboratory analysis were used to study the soil nutrient distribution characteristics of maize breeding base in Dunhuang, Gansu Province, Sanya City, Hainan Province. The results showed that: the base of soil acid reaction, the proposed application of quicklime p H value to adjust the soil slightly acidic; soil organic matter, available nitrogen and available potassium general lack of available phosphorus moderate; exchangeable calcium and exchangeable magnesium content of moderate, effective Iron, manganese, copper, zinc rich in content.
