对北仑区各乡镇(街道)土壤样品的分析测定结果表明,北仑区耕地土壤有机质含量较高,土壤速效养分有效磷总体过量,区域间存在很大的不平衡性;全区土壤酸化程度严重,土壤阳离子交换量普遍偏低,保肥能力差。同时,笔者提出了实施酸性土壤改良,降低土壤酸化程度;增施有机肥,培肥地力;推广应用测土配方施肥技术,提高肥料利用率;合理轮作提高土壤养分含量等措施。
The analysis and determination of soil samples from townships (streets) in Beilun district showed that soil organic matter content in cultivated land was high in Beilun district, and total available and available phosphorus in soil was excessive. There was a great imbalance between the areas. Soil acidification was serious in the whole area, Soil cation exchange generally low, poor fattening ability. At the same time, the author put forward some measures such as implementing acid soil improvement, reducing soil acidification degree, increasing organic fertilizers and fertilizing fertilizers, popularizing and applying soil testing and formula fertilizing techniques, improving fertilizer utilization rate, and rational rotation to increase soil nutrient content.
