放牧强度对青藏高原高寒草地牧草生产性能及营养品质影响的研究进展
Research progress on effects of grazing intensity on forage production performance and nutritional quality in alpine grassland on Qinghai-Xizang Plateau
摘要
Abstract
Grazing intensity is a key factor affecting the production performance and nutritional quality of forage in alpine grasslands.Moderate grazing can maintain root health and photosynthetic efficiency,improve vegetation diversity and community stability.Although heavy grazing can improve the nutritional quality of grass in the short term,such as increasing the content of crude protein,crude fat,and crude ash,and reducing the content of neutral detergent fiber and acid detergent fiber,long-term heavy grazing can lead to grassland degradation and decreased grass productivity.This study focuses on exploring the effects of different grazing intensities on the production performance and nutritional quality of alpine grassland forage in Qinghai-Xizang Plateau region,aiming to clarify the appropriate grazing intensity and provide reference for the health and sustainable development of alpine grassland ecosystems.Based on existing research,it is recommended to control the appropriate livestock carrying capacity in the high-altitude grasslands of the Qinghai-Xizang Plateau within the range of 5 to 6 sheep units/hm2.关键词
