为了改变生产者在冬小麦基肥施用上的盲目性和随意性,解决因施肥不当造成的小麦产量难以提高的问题,采用大田试验方法,在典型地块开展了生产者常用的几种复（混）合肥基施对小麦的影响对比试验研究。结果表明,2种含有N、P、K三元素的复（混）合肥,较其他处理极显著提高了小麦产量和效益,其中N、P2O5、K2O配比为18-18-6的配方肥每公顷基施525kg、675kg,其产量、效益差异均不显著,但均比配比为15-20-5的配方肥增产达极显著,效益达显著;得出N、P2O5、K2O配比为18-18-6的配方肥比较适合永年县小麦土壤,适宜用量为每公顷基施525～675kg。

In order to alter the producer’s blindness to the base fertilizer application of winter wheat, resolve the low yield of wheat caused by irrational fertilizer application, a field trial with a cv.‘Liangxing 99’was carried out for comparing the effects of several common types of compound （mixed） fertilizer on winter wheat. It is found that 2 types of compound （mixed） fertilizer containing N, P and K increased wheat yield and economic benefits significantly compared with the other types. The compound （mixed） formula fertilizers with the N：P2O5：K2O ratio of 18：18：6 increased wheat yield and economic benefits significantly compared with the compound fertilizer with the N：P2O5：K2O ratio of 15：20：5, but insignificant differences in grain yield and economic benefits were found between the rates of 525 kg/hm2 and 675 kg/hm2 in the two compound fertilizers. Hence, the compound （mixed） fertilizer with the N：P2O5：K2O ratio of 18：18：6 was well suitable to Yongnian soil and wheat, and its proper applied rate was 525-675 kg/hm2.
