我县从19 83年开始试种杂交早稻威优35和威优98,三年来亩产在500公斤左右,每亩大田用种量3—3.5公斤,全生育期120—125天。由于生育期偏长,用种量偏多,致使杂交早稻难于推广。为了把杂交早稻尽快普及应用到生产上去,实现早稻高产,我们在1986年进行了杂交早稻威优49旱秧省种高产 In 1983, we experimented on the hybrid rice “Weiyou 35” and “Weiyou 98”. In the past three years, the yield per mu was about 500 kilograms. The yield per acre was 3-3.5 kilograms and the whole growth period was 120-125 days. Due to the long growth period, the use of too much, resulting hybrid rice is difficult to promote. In order to popularize the early hybrid rice applied to the production as soon as possible to achieve high yield of early rice, we carried out in 1986 hybrid rice Weiyou 49 drought seedlings planted high yield
