【摘要】 20 0 0年和 2 0 0 2年对河北农户冬小麦和玉米施用肥料品种结构的调查结果表明 ,施肥中普遍存在重冬小麦而轻夏玉米的现象。冬小麦基肥主要是磷酸二铵 ,追肥主要是尿素 ;夏玉米追肥用量高于基肥 ,主要品种是尿素 ;磷酸二铵和三元复合肥则是基肥的主要品种。提高河北省冬小麦、夏玉米的肥料利用率 ,一方面要指导农民科学施肥 ,平衡区域施肥量 ;另一方面化肥企业也应针对不同农作物的特点 ,开发、生产适宜的肥料品种更多还原

【Abstract】 Based on the investigation on Hebei farmers in 2000 and 2002, consumption structure of fertilizer varieties are analyzed on winter wheat and maize. The results show a preferential input of fertilizers on wheat than on maize. To winter wheat, the main basal fertilizer is DAP and top dressing urea. To maize, the main basal fertilizers are DAP and compound fertilizers, and its top dressing is urea, too. For raising fertilizer efficiency on wheat and maize, balance fertilization is necessary and the producers must supply suitable varieties for different crops.更多还原
