威优64在我区种植以来,1985年统计面积在17万亩左右,平均亩产450多公斤,部分田块达600多公斤,一般比常规晚稻每亩增产100—150公斤。为了弄清它的生育特性,指导大面积生产,自1984年起,连续三年对威优64进行了较系统的观察。地点设在汉川县农科所、应山县农科所。常规一般育秧技术与大面积相同。二段育秧采用温室人工寄插。
Since Weiyou 64 was planted in our district, the statistical area in 1985 was about 170,000 mu, with an average yield of over 450kg per mu and more than 600kg on some plots. Generally, the yield was 100-150kg per mu than conventional late rice. In order to clarify its fertility characteristics and guide the large-scale production, Weiyi 64 has been systematically observed for three consecutive years since 1984. The location is located in Hanchuan County Agricultural Science Institute, Ying Shanxian Institute of Agriculture. Conventional general seedling technology and large area the same. Two sections of seedlings using greenhouse artificial post.
