本研究应用土壤养分状况系统研究法对赣东北红壤试验区八种代表性土壤进行了pH、有机质、全氮、全磷、缓效性钾、活性酸以及11种大、中、微量元素速效含量的实验室分析,进行了对磷、钾、硫、铜、锌等元素的吸附试验和温室栽培试验。在掌握土壤供肥能力及其对养分的吸附固定能力基础上,综合评价土壤养分状况,确定盆栽试验不同施肥处理,进一步探明了各种土壤的养分限制因子及其对产量影响的程度。 In this study, soil organic matter status was used to study the effects of pH, organic matter, total nitrogen, total phosphorus, slow-acting potassium, active acids, and the contents of 11 large, medium and trace elements in eight representative soils of the northeastern Jiangxi red soil region Of the laboratory analysis of phosphorus, potassium, sulfur, copper, zinc and other elements of the adsorption test and greenhouse cultivation experiments. On the basis of grasping soil fertility and its ability to adsorb and fix nutrients, soil nutrient status was comprehensively evaluated, and different fertilization treatments in pot experiment were determined, and the limiting factors of nutrients and the degree of impact on yield were further ascertained.
