1994年龙山县种子公司在县商品粮基地新城乡的新城村八组杨成双家的责任田进行了优Ⅰ46(优ⅠA×密阳46)制种高产攻关。通过几项新技术措施的实施,获得了成功。经县有关单位验收,制种面积800平方米,实际产量为483公斤,平均每667平方米产量达402.5公斤,异交结实率高达70.7％。其高产技术如下:
In 1994, Longshan County Seed Company conducted the high-yielding seed production plan of You Ⅰ46 × 46 in Yangcheng Shuangjialou’s responsibility field in Xincheng Village, Xincheng Township, County Commercial Grain Base. Through the implementation of several new technical measures, success has been achieved. The acceptance by the relevant county units, seed production area of 800 square meters, the actual yield of 483 kilograms, an average yield of 402.5 kilograms per 667 square meters, outcrossing rate as high as 70.7%. Its high-yielding technologies are as follows:
