摘要
通过对10多年麦田施肥试验及定位试验资料的处理,分析了不同产量水平的麦田施肥效益:有机肥与化肥配施可显著提高肥效,低产麦田需要的有机肥比例高于高产麦田,中产麦田的综合施肥效益最高。与10年前相比,麦田的需磷比例和磷肥肥效有较大提高。
Through over 10 years of fertilizer application and position-fixed experiment of wheat, fertilizer aplication efficiency in wheat field under different output levels were analyzed. Result showed that the fertilizer use efficiency was greatly improved when organic fertilizer and chemical fertilizer was used together. In low-yielding wheat field, it required more organic fertilizer than that in high-yielding field. The efficiency of comprehensive fertilizer application in the medium yielding field was the best. Compared with that of 10 years ago , phosphorus requirement of wheat and the efficiency of phosphorus fertilizer application have been greatly increased.
