我省西部地区有宜牧草原2600多万亩。素有产量高,草质好而弛名中外,是我省发展畜牧业的重要物质基础。但由于多年来经营管理不善毁草开荒,过牧等原因造成草原沙化、碱化、退化现象十分严重。为改变这种状况,促进畜牧业的发展,1981年下达本项课题为省重点科研项目,由省畜牧研究所与省齐齐哈尔种畜场共同承担。项目从1981年开始,至1984年结束,要求建立人工草场和改良天然草场各5000.0亩,计1万亩。产量指标人工草场
There are more than 2600 mu of grassland in the western region of our province. Known for high yield, good grass and relaxation at home and abroad, is the development of animal husbandry in our province an important material basis. However, desertification, alkalization and degradation of grasslands are very serious due to bad management and wasteland wasteland and animal husbandry over the years. In order to change this situation and promote the development of animal husbandry, this project was issued in 1981 as a key scientific research project of the province, which is jointly undertaken by the Provincial Institute of Animal Husbandry and the provincial Qiqihar Stallion Farm. The project started in 1981 and ended in 1984, requiring the establishment of artificial grassland and improvement of natural grassland of 5000.0 mu and 10,000 mu respectively.
