Abstract: Guanyang County is located in the alpine mountainous area of northern Guangxi. By vigorously promoting the cultivation mode of "one season of high-quality rice + reclaimed rice", it can effectively use the temperature and light resources, improve the multiple cropping index, and increase the grain output. In order to increase rice yield, improved varieties are the key. Through the comparison experiment of regeneration of new high-quality rice varieties, new varieties of high-quality rice, such as Wantaiyou Meizhan rice, Wantaiyou 3158, were selected to provide technical support for local large-scale promotion in the future.
