我县试种杂交水稻,是从1976年开始的,当时种植面积611亩。以后逐年扩大,1978年曾发展到17万9千亩,占二晚面积的70％。但1979年又缩减到9万3千余亩。由于大面积推广杂交水稻,促进了我县粮食生产的发展。总的来说,大家对杂交水稻反映是好的,绝大多数人认为杂交稻具有产量高,适应性广,耐肥抗倒,抗旱能力强,节省种子等优点。但也有些相反的看法,认为杂交水稻是:远看三层楼,穗大不钩头,满满一箩谷,一手提着走。我们认为这种说法是不全面的。因为这不是杂交稻本身的问题,而是由于种子不纯,栽培不当,管理不善所造成的结果。
I County trial hybrid rice, is from 1976 onwards, when the planting area of 611 acres. Since then, it has been expanded year by year. In 1978, it had grown to 179,000 mu, accounting for 70% of the area of the second night. However, it was reduced to more than 93,000 acres in 1979. As a large area to promote hybrid rice, and promote the development of grain production in our county. In general, everyone is good about hybrid rice. Most people think that hybrid rice has the advantages of high yield, wide adaptability, resistance to fertility and lodging, drought resistance and seed saving. However, there are also some contradictions that hybrid rice is: three-story building from afar, big spike, filled with a valley, with one hand and walked. We think this argument is not comprehensive. Because this is not the problem of hybrid rice itself, but the result of impure, poorly cultivated and mismanaged seeds.
