| 摘 要： | 采用盆栽试验,研究了氮锌配施对玉米干物质积累、生长性状及产量的影响,结果表明,氮肥和锌肥都能增加玉米的干物质积累、株高、穗长、穗粗、穗粒数、百粒重及产量,且除穗长外氮肥的作用大于锌肥;氮锌配施效应大于单施氮肥或锌肥,氮锌交互效应为正,N1Zn1是最佳处理组合;综合考虑玉米生物产量、子粒产量、经济效益及环境污染,以施N1... |

| Abstract: | Effect of combined application of N and Zn on dry material accumulation,growth traits and yield in maize were studied by pot experiment,the results showed that the dry material accumulation,plant height,ear length,ear diameter,kernel number,kernel weight and yield could be increased by N and Zn fertilizers,as well as the role of N was greater than Zn except ear length;Effect of combined application of N and Zn was greater than single of N or Zn,interactive effects of N and Zn were positive,and N1Zn1 was the... |
| Keywords: | combined application of N and Zn maize dry material accumulation growth traits yield |
