摘  要:
在辽宁省辽中县盐化草甸型水稻土上设置田间定位试验。经5年观测结果表明,施用肥料特别是有机无机肥配合施用,兼有提高土壤肥力水平和加强作物营养的双重功效,水稻产量由不施肥处理的 3 495kg·hm-2提高到 7 350kg·hm-2。在配施组合中,以施猪圈粪 1.5t.hm-2,化肥 N 75~ 90kg·hm-2, P2O5 30~ 45kg·hm-2为最佳。

摘  要:
Five-year location terts in saline meadow rice soil in Liaozhong County of Liaoning Province were made. The results showed that fertilizers, especially the combination of organic and chemical fertilizers increased soil productivity and improved plant nutrition. Experimental data indicated that rice yield increased from 3495kg·hm-2 of no fertilizer treatment to 7350kg·hm-2 of the fertilizer treatment. Among the fertilizers combinations, the combination of pig pen manure 1.5t·hm-2, chemical N 75-90kg·hm-2 and PRO, 30 - 45kg·hm-2 is the most suitable.
