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。
The results of field experiment and laboratory analysis for 8 consecutive years show that the organic-inorganic fertilizer application is more than the two effects of single application and the organic-inorganic fertilizer is better than the two combined application of nitrogen and nitrogen, the corresponding value is positive, Poor, most of the negative response, and nitrogen and phosphorus fertilizer application shows a certain yield advantage. Organic and inorganic fertilizer with obvious fertilizer effect, of which organic manure and nitrogen and phosphorus with the best allocation of phosphorus on the available phosphorus increased, no fertilizer and applied nitrogen fertilizer little or no change in soil nutrients.
