放牧生态系统中的组织物质循环及其在牧场管理中的应用

综述了组织物质循环的理论及其在牧场管理中的应用。放牧过程中牧地草丛内的物流和能流循环是维持放牧生态系统平衡的重要基础,进行牧地草丛中植物组织循环,特别是其生长和萎蔫死亡的动态分析,为草地的有效利用提供了理论依据。文中对于牧地草丛内及刈牧过程中的组织物质循环,连续放牧及间断放牧条件下的组织物质循环进行了重点分析论述。建议在中国各类型草地上应用组织物质循环理论开展放牧管理研究,以推动草地管理理论和实践的发展。

Tissue Turnover in the Grazing Sward and Grazing Management

The flux of tissue and energy in the grazing sward maintains the balance of this system, while the analysis of the tissue turnover in grazing sward, such as the process of growth and senescence in the sward, provides the basic information for effective pasture utiliaztion. This paper summarized the tissue turnover in the grazing sward and grazing management. The process of tissue turnover in grazing sward, the effects of defoliation on tissue turonver, and the tissue turnover under continuous and intermittent grazing systems were discribed.
