不同时期施肥对农菁6号无芒雀麦种子生产性能的影响

Effects of Fertilization Period on Seed Yield of Bromus inermis of Nongjing No.6

采用单因素随机区组设计,研究了不同时期施肥对无芒雀麦(Bromus inermis)种子生产性能的影响。结果表明:不同时期施肥处理间差异显著(P<0.05),以返青期和抽穗期施肥的种子产量最高(平均达到906.6 kg.hm-2)。因此,在返青期或抽穗期施肥是提高无芒雀麦种子产量的有效途径之一。

The seed productivity of Bromus inermis of Nongjing No. 6 with fertilization at different stages were studied with the single-factor random block design. It was indicated that there were significant differences in seed yield among the different treatments （P〈0.01） and the seed yield for fertilizing ranked the highest with 906.6 kg·hm^2 at green-turning stage and heading stage. Therefore, fertilization at green-turning stage or heading stage was one of the best way to increase seed yield of Bromus inermis.
