It has outstanding features of high quality, high yield, drought resistance, and disease resistance. Hanzhong Institute of Agricultural Sciences introduced Qingshu 9 from Dingxi County in Gansu Province in 2010. Through years of experiments and demonstrations, the average yield of Qingshu can reach up to 53.14 t/hm^2 with the maximum yield to 63.77 t/hm^2.展开更多

" In this paper,the high yield and efficient cultivation techniques of rice under the rice-fish intergrowth model in Chengdu was introduced from the aspects of selecting good paddy fields for fishing,using appropriate rice varieties,soaking disinfection,timely sowing and nurturing strong seedlings,reasonable close planting,reasonable fertilization,scientific water management,scientific pest control and rice harvests.展开更多
