摘要
分蘖是草坪草的重要特征之一,直接影响草坪草的耐践踏性及坪用价值。从草坪草分蘖类型、形成过程及分蘖形态特征等方面阐述了草坪草的分蘖特征,并从生长素、细胞分裂素等内源激素及碳水化合物,氮素等营养物质的类型和含量分析探讨了影响草坪草分蘖的调控机理。以期为草坪草分蘖调控机制的进一步研究及针对性地提出养护对策提供参考。
Tillering is one of the most important features of turfgrass,it directly influences the tramp resistance and use value of the turf.This paper demonstrates the turfgrass tillering characteristics based on the types of turfgrass tillering,the forming process and the morphological characteristics of tillering.It was also analyzed and discussed about the control mechanism of turfgrass tillering,based on the influences of the endogenous hormones,such as auxin,cytokinins,etc,and the type of nutrient component and content of carbohydrates and nitrogen,etc.It is expected to provide references to further researches on the control mechanism of turfgrass tilleing and turfgrass management.
