连续施用有机肥与化肥对黄绵土的培肥效应
- Title:
- Effect of Sustained Applying Organic Matter and Chemical Fertilizer on Improving Fertility of Loessal Soil
- 摘要:
- 连续8年的田间试验及室内分析结果表明：有机无机肥配施增产效应大于两者分别单施效应，有机肥与氮肥配施效果较好，联应值为正值，与磷肥配施效果较差，多数是负联应，与氮磷肥配施显示一定的增产优势。有机无机配施有明显的增肥效应，其中有机肥与氮磷配施效果最佳，施磷上壤有效磷增加，不施肥及单施氮肥土壤养分变化甚微或呈下降趋势。
- Abstract:
- The sustained 8 years field experiments and laboratory analysis shows the increasingyield effect of organic matter mixed with chemical fertilizer is higher than that of organic matter or chemical fertilizer,and organic matter effect mixed with N is high, its mixed with P is low,its mixed with N and P is very high.Organic matter mixed with chemical fertilizer may improve soil fertility with best effect as it mixed with N and P.Soil available P is increased as applying P and soil nutrient change is not obvious or its content is decreased gradually as only applying nitrogen.
