摘要: 本文采用田间试验研究了氮磷钾锌肥施用对鄂北岗地小麦产量及产量性状的影响。结果表明：在P < 0.05水平上，氮磷钾锌肥配合施用明显提高了小麦株高、穗长、有效穗和穗粒数，增加了各时期干物质积累量，进而增加产量。鄂麦170和郑麦9023产量均以NPKZn处理最高，分别达到527.82和518.04 kg/667m2，鄂麦170施用氮、磷、钾和锌肥的增产率分别是40.81%、16.26%、11.14%和9.70%，郑麦9023施用氮、磷、钾和锌肥的增产率分别是47.47%、16.38%、17.92%和18.16%。
Abstract: A field experiment was conducted from 2016 to 2017 in highland area in northern Hubei Province. The objective of the research was to investigate the effects of nitrogen (N), phosphorus (P), potassium (K) and zinc (Zn) fertilizer on yield trait of Emai 170 and Zhengmai 9023. The results showed that the combination application of N, P, K and Zn (NPKZn) increased plant height, spike length, effective spike and grain number per spike of wheat significantly (P < 0.05). The amount of dry matter accumulation in each period was also increased. The yield of NPKZn treatment was the highest among the 6 fertilizer treatments with 527.82 kg/667m2 for Email 170 and 518.04 kg/667m2 for Zhengmai 9023. Compared with -N, -P, -K and -Zn treatment, yield of NPKZn was improved 40.81%, 16.26%, 11.14%, 9.70% for Emai 170 and 47.47%, 16.38%, 17.92%, 18.16% for Zhengmai 9023.
