This book not only describes the Chinese system of cold high-latitude forage collection, preservation, identification, breeding, propagating, and the achievements of many studies and experiments, but also discusses the alpine grasslands region and distribution of scientific management, and further covers the industrialization of the grass industry.
The development of the grass industry in the past happened mostly in mid-latitude areas as the center, with north and south expansion in two ways. Extensive scientific literature is available for these areas. The boreal region, including the Heilongjiang region, is not fully studied. The construction of China's agricultural system in the Heilongjiang region has its advantages. Local food production has become increasingly important at the same time, and there are various concerns on the ecology of natural and cultivated grassland.
Summary in Chinese:
草 业的发展过去多以中纬度地带为中心，向南北两方面扩张。大量科学文献也以这些地区为主。而寒温带，如黑龙江所在的位置，研究得不太充分。我们都知道，在中 国农业系统建设中，黑龙江地区具有后发优势。该地粮食生产显得越来越重要的同时，其天然草原和栽培草地，自然引起生态和生产诸方面的关注。
