扬辐籼2号(原代号“381”),系江苏省里下河地区农科所利用~(60)Co—γ射线辐照IR1529—68—3—2选育而成,1989年参加江苏省区试,产量与杂交稻汕优63相当。1990年被破格参加省水稻生产试验,比对照盐籼150增产6.61％;同年在江苏、湖北、安徽三省12个县进行大面积示范,面积达2000多亩,平均亩产569.2kg,高产田块达689.2kg,深受群众欢迎。1991年在以上三省迅速扩大到10万多亩。生产实践证明,扬辐籼2号集高产、抗病、优质于一体,具有良好的综合性状和较好的适应性,并具有一般常规品种难以兼顾的高产基础和稳产性能。现将该品种的栽培特性及生产技术关键介绍如下。 Yangxianxian No.2 (formerly “381”) was bred from IR1529-68-3-2 using ~ (60) Co-γ-ray irradiation by the Lixiahe Agricultural Sciences in Jiangsu Province. In 1989, Provincial test, yield and hybrid rice Shanyou 63 quite. In 1990, he was unsuccessfully participated in the pilot rice production in the province and gained 6.61% more than the control salt indica 150. In the same year, large-scale demonstration was carried out in 12 counties in Jiangsu, Hubei and Anhui provinces with an area of ​​2000 mu and an average yield of 569.2 kg per mu, Up to 689.2kg, welcomed by the masses. In 1991, the above three provinces rapidly expanded to 100,000 mu. Production practice has proved that Yangfu Indica 2 sets high yield, disease resistance, high quality in one, has good overall traits and better adaptability, and has the general conventional varieties difficult to take into account the high yield base and stable performance. Now the varieties of cultivation characteristics and production techniques are described below key.
