南方喀斯特地区草地的放牧利用技术规程

Technical Rules of Grazing Utilization of Grassland in Karst Area in Southern China

中国南方喀斯特地区的自然地理特征造就了其独特的生境,其出露或埋藏的基岩主要为可溶性岩(碳酸盐岩、硫酸盐岩、卤岩等),在水的化学溶蚀作用下,地表渗漏严重,地表水匮乏。且成土速率慢,土层较薄,保水能力较差,地表土壤多为中性至弱碱性。这对牧草和家畜生产都提出了相应的要求。为了规范中国南方喀斯特地区家庭牧场生产,本规程对该地区草地放牧利用策略、放牧时期、放牧留茬高度、放牧次数和放牧利用方法等提出了具体要求和规定。该生产技术规程对中国南方喀斯特地区草地放牧管理具有重要的现实指导意义。

The natural geographical features of karst area in southern China has created its unique habitat, which bedrock exposed or buried are most soluble, such as carbonate rock, sulfate salt rocks, halogen rock, etc. And the surface water is scarcity under the chemical corrosion and the leakage of water. And the soil develops slowly and thin in depth, the surface soil is neutral to weak alkaline. So the grass and livestock production were put forward the corresponding requirements. Therefore, these rules make the concrete requirements and provisions on meadow in the region of grazing strategy, grazing period and grazing stubble height, number of grazing and grazing method. Which are guiding the grassland grazing management in karst area in southern China.
