| 摘 要： | 利用“3414”肥料试验,研究了江汉平原棉麦套种方式下小麦对养分的利用效率.结果表明,江汉平原小麦NPK配施增产效果最好,增产量和增产率分别为1 838.7 kg/hm2和79.3％,每千克养分可增产小麦6.7kg；NP、NK、PK配施,以NP配施的产量最高,NK配施的产量次之,PK配施的产量最低,研究区域N是影响小麦产量的重要因子. |

| Abstract: | The nutrient use efficiency of wheat in cotton-wheat interplanting system in Jianghan plain was studied using ’3414’ fertilizers tests.When N,P,and K fertilizers were applied evenly,wheat had best yield-increasing effect,the production increased and increasing rate were up to 1 838.7 kg/hm2 and 79.3% respectively.Among the combined application treatments of N and P,N and K,P and K,the yield of wheat was highest in N and P combined application treatment,then N and K,the lowest was P and K.N fertilizer was the most important factor affecting wheat yield in Jianghan plain. |
| Keywords: | Jianghan plain wheat ’3414’ fertilizer experiment nutrient use efficiency |
