| 摘 要： | 为明确番茄的氮肥利用特性,从而为因种施肥和提高氮肥利用效率提供依据。以吉林省市场上常见的25个番茄品种为试材,对其氮肥吸收利用率(RE)、氮肥生理利用率(PE)、氮肥农学利用率(AE)和氮肥偏生产力(PFP)的差异进行比较。结果表明,不同番茄品种的RE、PE、AE、PFP均存在显著差异。聚类分析显示,产量和氮肥利用效率(NUE)较高的番茄品种有朝研219、佳粉19、倍盈、赛欧1号和瑞琦1号。相关分析表明,提高氮收获指数,有利于产量和NUE的提高。

| Abstract: | In order to understand the characteristic of nitrogen use and provide guidance for fertilization in accordance with varieties and high nitrogen use efficiency.25 cultivars of tomato widely used in Jilin province were employed to evaluate their nitrogen use efficiencies(NUE) by indices of agronomic efficiency(AE),recovery efficiency(RE),physiological efficiency(PE),and partial factor productivity(PFP).The results showed that there were significant genotypic differences of N use efficiencies in terms of RE,PE... |
