我县地处桂南,有水田35万亩,平均每人不足7分,是个人多田少的县。要提高粮食总产,就得靠提高单位面积产最,而发展杂交水稻,是提高单位面积产量的有效措施。从1978年起,我县每年种植杂交水稻面积达20多万亩,占水稻面积的40—50%,单 My county is located in Guinan, a paddy field of 350000 acres, an average of less than 7 points per person, is a few individual Tada less county. If we want to increase the total output of grain, we must rely on the improvement of the unit area yield, and developing hybrid rice is an effective measure to increase the yield per unit area. Since 1978, the county has planted more than 200,000 mu of hybrid rice each year, accounting for 40-50% of the rice area.
