天山北坡山地草甸牧草生产量结构的研究

Biomass structure of mountain meadow forage on the northern slopes of the Tianshan Mountains

对天山北坡山地草甸主要牧草进行生物量测定,研究其不同生长高度的生物量变化及茎、叶、花穗的生物量分布格局,探讨牧草生长发育动态变化规律,了解山地草甸牧草生产量结构,为提高牧草利用率及合理部署草场放牧提供指导。

The biomass was determined for major forage species of mountain meadows on the northern slopes of the Tianshan Mountains, as well as the change in biomass with height of plant growth and the biomass distribution of leaf, stem and flower spikes. Patterns of forage growth and development are discussed. This study has been done to provide a guide to improving forage utilization and rational grazing.
