摘　　要：在冬季广州地区,对粤选1号匍匐翦股颖喷施氮肥、氮-铁肥,研究不同叶面肥对其生长、色泽及耐低温能力的影响。结果表明:喷施氮肥,能有效加快植株生长,增强其耐低温胁迫能力,但叶绿素含量未明显上升;喷施氮-铁肥,叶绿素含量显著上升,叶色变深,但植株生长速度降低,耐低温能力未增强。With Agrostis stolonifera L. cv. Yuexuan No. 1 as the test material, the effects of different foliar fertilizers on the growth, color and low temperature tolerance of Agrostis stolonfera L. cv. Yuexuan No. 1 were studied. The results showed that spraying nitrogenous fertilizer could improve the growth and cold tolerance of Agrostis stolonifera L. cv. Yuexuan No. 1. However, chlorophyll content of the leaves was not increased significantly. Spraying nitrogenous fertilizer and iron fertilizer at the same time could deepen leaves＇ color because the chlorophyll content increased, however, the growth and low temperature tolerance of Agrostis stolonifera L. cv. Yuexuan No. 1 were not increased.
