为了缓和双抢的劳力矛盾,以及向丘陵山区扩种双季稻,增加粮食产量,我们从1987年起开始试验用早稻种子和晚稻种子按比例掺合同播同插、栽植一季、收割两季的“早晚稻两季混栽”方法,经2年试验,取得成功。1988年用50—70%的湘早籼1号、湘早籼3号、威优49种子掺合30—50%的威优6号 In order to ease the double-grab labor conflicts and to expand double-cropping rice and increase grain yield in hilly areas, we started experimenting with early sowing seeds and late rice sowing seeds in proportion to sowing and sowing the same seeding line in 1987 and planting two seasons of “ Morning and evening rice mixed planting season ”method, after 2 years of testing, success. In 1988, 50-70% of Xiangsanxian 1, Xiangzaoxian 3 and Weiyou 49 were blended with 30-50% Weiyou 6
