采用适当的农业管理措施,就能提高植胶土壤的肥力。最重要的措施是施用混合肥,即施含有氮(主要是氨态氮或硝态氮)、磷(主要是磷矿粉)、钾(氯化钾)和镁(硫镁矾)的化合物。连续施用这些肥料会影响土壤的化学组分。为了评定土壤的养分状况,作了土壤常规测定,测定项目是土壤 pH、有机碳、全氮、酸提取的阳离子(钾、钙、镁、锰)、全磷、可交换阳离子(钾、钙、镁)、可溶性磷和阳离子交换量。本文根据若干大田长期农业试验的
Using proper agricultural management practices can increase the fertility of the plasticized soil. The most important measure is the application of a compound fertilizer, a compound containing nitrogen (mainly ammonia nitrogen or nitrate nitrogen), phosphorus (mainly rock phosphate), potassium (potassium chloride) and magnesium (periclase). The continuous application of these fertilizers affects the chemical composition of the soil. In order to evaluate the soil nutrient status, soil routine determination was made. The determination items were soil pH, organic carbon, total nitrogen, acid extracted cations (potassium, calcium, magnesium and manganese), total phosphorus, exchangeable cations (potassium, Magnesium), soluble phosphorus and cation exchange capacity. This article is based on a number of field long-term agricultural experiments
