| 摘 要： | 采用抽样调查收集的农田施肥数据,结合耕层土壤养分状况,分析了阜平县主要粮食作物的农田施肥状况和养分结构.结果表明:阜平县农田养分补充主要依赖化学肥料,有机肥施用量很小;且普遍"重氮轻磷",氮磷比例严重失衡;磷素养分供应不足,不但阻碍氮素养分的利用效率,也严重制约玉米产量的进一步提高.今后农田施肥,应当重视施用有机肥,控制氮素化肥用量,增加磷素养分比例,适当补施钾肥.

| Abstract: | Collecting fertilization data by spot check,combining with the nutrient qualilty of the furrow soil,we analyzed the fertilization and nutrient structure on the food crop farmland of Fuping County.The result shows that the nutrient supply on the farmland of Fuping County is mainly depending on fertilizer,and rarely on organic fertilizer,at the same time the proportion of nitrogen and phosphorus is quite unbalance.Lack of phosphorus not only counterwork the utilizing of nitrogen but also restrict the improvement of maize output.For the future we should attach importance to organic fertilizer on farmland,control the dosage of nitrogen fertilizer,increase the proportion of phosphorus and add kalium fertilizer properly. |
