水稻是我国主要粮食作物,在我国的分布范围很广,北至黑龙江的漠河,南至海南岛,西至西藏高原,东至沿海各省,都有水稻栽培。由于各地区的自然条件和生产条件不同,形成了我国水稻栽培制度的多样化,为今后因地制宜发展水稻生产奠定良好的基础。水稻在我国的栽培历史也很久,约4600年以上。我国劳动人民经过长期的水稻栽培和选种,培育出大量的适应各地区各种栽培制度的品种类型,为今后进一步创造新品种提供丰富的品种资源。把良种和高产结合起来,解决我国水稻栽培上所存在的问题,促进水稻生产的发展,是我国农业生产上的一项重要任务。
Rice is a staple food crop in China. Its distribution in our country is very wide. From the north to the Mohe in Heilongjiang Province, to the Hainan Island in the south, to the Tibetan Plateau in the west and to the coastal provinces in the east, there is rice cultivation. Due to the different natural conditions and production conditions in various regions, the diversification of rice cultivation system in our country has been formed, laying a good foundation for the future development of rice production according to local conditions. Rice cultivation in our country has a long history, about 4600 years. After long-term rice cultivation and seed selection, working people of our country have cultivated a large number of varieties suitable for various cultivation systems in various regions and have provided rich variety resources for further creation of new varieties in the future. It is an important task for China’s agricultural production to combine improved varieties with high yields, solve the problems existing in rice cultivation in our country and promote the development of rice production.
