- 摘要:
- 通过对鞍山市 724个不同地区和不同土壤利用类型耕地土壤样品有机质、全氮、碱解氮、有效磷、速效钾等 5项土壤养分测试与统计分析, 按照评价指标体系, 对鞍山耕地土壤肥力现状进行科学合理的评价。评价结果表明, 鞍山市耕地土壤有机质、全氮整体上属于稍缺水平, 碱解氮和速效磷属于丰富水平, 速效钾属于中等水平。 在农业生产上应增施有机肥, 适当增施氮肥, 减少磷肥的施用量, 钾肥可保持现有施肥水平。
- Abstract:
- Through to the Anshan 724 different areas and the different soil use type farming soil sample organic matter, theentire nitrogen, the alkaline hydrolysis nitrogen, the effective phosphorus, the fast-acting potassium and so on 5 item ofsoil nutrient test and the statistical analysis, according to the appraisal target system, carries on the science reasonable ap-praisal to Anshan farming soil fertility present situation.The appraisal result indicated that, in Anshan farming soil ulmin,the entire nitrogen whole belongs lacks the level slightly, the alkaline hydrolysis nitrogen and the fast-acting phosphorusbelong to the rich level, the fast-acting potassium belongs to the medium level.Should increase in the agriculturalproduc-tion executes organically fat, increases suitably executes the nitrogenous fertilizer, reduces the phosphate fertilizer the em-ployment quantity , the potassium fertilizer may maintain existing applies fertilizer the level.
