摘    要:国家科技部对未来15年畜牧业发展技术提出战略政策。指出要加大草原保护力度,合理开发1333.3万hm^2南方草山草坡及4000万hm^2农牧交错带。据此,农田草地系统耦合将成为我国家庭承包经营制农业的主要生产方式,尤其是农牧交错带和我国南方地区。分析农田草地系统耦合生产模式,管理核心是减少农田和草地系统营养物质的外流损失。生产的关键技术有草田轮作技术,农田作物秸秆再利用技术,家畜宿营技术和全日制放牧技术。

关 键 词:农田  草地  系统耦合

Abstract:The Chinese Ministry of Science and Technology has put forward development strategy policy for the pastoral livestock industry for the next 15 years in China. This policy includes strengthening the protection of natural grassland in northern China. High yield pasture is to be developed on 13.3 million hectares in southern China and 40 million hectares in the agro-pastoral transition zone. Therefore, integrated crop and pasture systems will become the major production way in the rural area of China, particularly in the agro-pastoral transition zone and southern rural areas. This type of system pattern has been analyzed. The core of management is to reduce nutrient loss. Key production techniques include forage and crop rotation, straw utilization, livestock night penning, and all day grazing. In addition, key techniques also include hay and silage making, and livestock production optimization.
Keywords:crop  pasture  system integration
