专用肥对春小麦产量及经济性状的影响

对春小麦专用肥在不同肥力的土壤上进行了试验研究。结果表明,春小麦施用专用肥具有明显增产效果,分别比对照增产12.13%～30.18%和17.87%～39.57%。专用肥配施硝酸铵增产效果更佳。在目前生产条件下,春小麦专用肥以比例合适的氮磷二元复合肥较为合理。

Effect of Wheat Special Fertilizer on the Grain Yield and Economic Character of Spring Wheat

The experiment of the wheat special fertilizer is carried out on the different soils. The results showed that applying the fertilizer to spring wheat had obvious effects on increasing yield and can increase yield 12.13%-30.18% and 17.87%-39.57%. The special fertilizer applied together with NH4NO3 had better effect. Under the present production condition,the wheat special fertilizer with N and P should be made.
