Shanyou 6 3 is an indica hybrid rice made by Zhenshan 97A and Minghui 63 used by Sanming Prefecture in Fujian Province. Introduced in 1984 in some counties and cities in our province for mid-crop cultivation, and in 1985 in some counties and cities conducted a double-night cultivation experiment. The results showed that Shanyou 63 was superior in yield increasing, and its ecological and economic benefits were superior to those of the current hybrid rice. It is suitable for mid-season and double-night cultivation in our province. In 1985, a total of 36.5 mu of double-night Shanyou 63 were planted in Chenzhou area, with an average yield of 482 kg per mu, an average of 371 kg per mu compared with that of late hybrid rice in that year, an increase of 30%, of which the highest yield was 617 kg. For double-night cultivation of Shanyou six three full growth period 128 ~ 135
