小麦种子田担负着两大任务,一是以尽可能高的繁殖系数,繁殖符合质量标准的优质种子;二是展示该品种的特征特性,以及相应丰产技术下的高产性能和品质性状。因此,与一般生产田不同,在管理上应抓好以下重点: 1.根据品种自身特点合理运用肥水。不同品种,其生理特性、生育特征各不相同,对肥水的需求及使用后的效应各有差异。总的来讲,小麦品种不外乎大穗型、多穗型、中间型三大类。 Wheat seed fields bear two major tasks. One is to breed quality seeds with the highest possible multiplication coefficient. The other is to show the characteristics of the cultivars and the high yield and quality traits under the corresponding high yield techniques. Therefore, different from the general production field, the management should focus on the following key points: 1. Make rational use of fertilizer and water according to the varieties’ own characteristics. Different varieties, their physiological characteristics, reproductive characteristics vary, the demand for fertilizer and the use of different effects. In general, the wheat variety is nothing more than the big panicle type, multi-spike type and intermediate type.
