【摘要】：在国家大力建设饲草料产业体系的背景下,对我国西南地区通过牧草产业发挥水热资源禀赋的研究有重要意义。黑麦草是我国西南地区种植量最大、种植面积最广的牧草。采用面板随机前沿模型,对2011-2014年我国西南地区72户农户黑麦草的种植技术效率和科技进步贡献份额进行了测算。结果表明:近年来,我国西南地区农户种植黑麦草的技术效率不断上升,2014年黑麦草种植技术效率在0.8~0.9的农户占47.22%,技术效率在0.9以上的农户占44.44%。黑麦草种植技术效率在不同区域差别较大,在奶业发达的优势区域,技术效率较高;而在奶业发展缓慢的地区,技术效率较低。黑麦草科技进步贡献份额达到了53.78%。因此,国家政策应该进一步支持和鼓励黑麦草生产技术的创新,政府应该着力加大促进黑麦草贮藏和加工技术的研发和推广,支持种养一体化,加大黑麦草经济价值通过家畜家禽高效转化途径的研究和技术推广力度。
[Abstract]:Under the background of the construction of forage industry system in our country, it is of great significance to study the endowment of water and heat resources through forage industry in Southwest China. Ryegrass is the most widely cultivated forage in southwest China. Based on the panel stochastic frontier model, 72 ryegrass farmers in Southwest China from 2011 to 2014 were used to measure the technical efficiency of ryegrass planting and the contribution of scientific and technological progress. The results showed that in recent years, the technical efficiency of ryegrass cultivation among farmers in southwest China was increasing. In 2014, the ryegrass planting efficiency was 0.80. 9% among farmers, and 44.44% among those with technical efficiency of 0. 9%. The technical efficiency of ryegrass cultivation varies greatly in different regions, and is relatively high in the areas where the dairy industry is developed, but low in the areas where the dairy industry is slow to develop. Ryegrass contributed 53.78% of its share of scientific and technological progress. Therefore, national policies should further support and encourage innovation in ryegrass production technologies, and governments should focus on promoting R & D and promotion of ryegrass storage and processing technologies, and support integration of breeding and breeding. To increase the economic value of ryegrass through livestock and poultry efficient transformation of research and technical extension.
