黄海稻区是指辽宁省的东南沿海东起丹东,西到大连的狭长地带。该稻区水田面积约为10万hm~2,是辽宁省的主要稻区之一。由于其特定的地理位置和气候条件,生产上应用的水稻品种与其它稻区迥然不同。 品种定向,从广义上理解,应该包含品种引、选、繁、育到应用的方向,既涉及长远建设又涉及及近期安排。为了改变水稻品种多、乱、杂的现象,搞好品种定向是使水稻优质高产的关键之一。
Yellow rice area refers to the southeast coast of Liaoning Province from east Dandong, west to Dalian strip. The rice paddy field has an area of about 100,000 hm ~ 2 and is one of the major rice planting areas in Liaoning Province. Due to their specific geographical location and climatic conditions, rice varieties used in production are quite different from other rice areas. Variety orientation, understood in a broad sense, should include the direction of variety selection, selection, propagation and application, both in the long-term construction and in the near future. In order to change the variety of rice varieties, chaos and miscellaneous phenomena, improving variety orientation is one of the keys to high quality and high yield rice.
