为研究豫北优质小麦施肥参数,采用“X”动态优化施肥试验设计,开展优质麦磷肥最佳施用量控制试验,试验结果表明随着施磷量的增加小麦产量增加,当亩施P2O5为8 kg时,小麦产量达到最高,之后随着施磷量的增加,小麦产量呈下降趋势。研究表明亩施纯N、P_2O_5、K_2O分别为12、8、6 kg/亩,能满足优质麦新麦26的优化施肥的需要。
In order to study the fertilization parameters of high quality wheat in the north of Henan Province, the optimum fertilization experiment of high quality wheat phosphate fertilizer was carried out by using “X” dynamic optimized fertilization experiment design. The results showed that with the increase of phosphorus application, At 8 kg, wheat yield reached the highest level, and then the wheat yield decreased with the increase of phosphorus application. The results showed that N, P_2O_5 and K_2O were 12, 8 and 6 kg / mu, respectively, which could meet the needs of optimal fertilization of high quality wheat and wheat.
