全国杂交水稻生产的发展已进入了第三个高峰期。主要标志是种植面积达到了1.5亿亩以上,在今后的三年内将突破两亿亩,比上一个高峰期扩大一倍,亩产要突破450公斤,比上一个高峰期提高50公斤。在全国杂交水稻大发展的同时,我省杂交水稻生产水平提高很快,1987年1200多万亩杂交水稻。平均亩产可达250公斤。人们在生产实践中日加深刻认识到,发展杂交水稻是促进粮食持续稳步增长的重大措施。目前杂交水稻生产已达较高水平,进一步发挥其增产潜力,难度虽大,但很有可能。纵观杂交水稻不断深化的技术,在我省应把握住以下主攻点:
The development of the national hybrid rice production has entered its third peak. The main symbol is that the acreage has reached more than 150 million mu and will exceed 200 million mu in the next three years, doubling the previous peak. The output of mu should exceed 450 kg, an increase of 50 kg from the previous peak. In the great development of hybrid rice in the country at the same time, the province’s hybrid rice production increased rapidly in 1987, more than 1,200 acres of hybrid rice. The average yield of 250 kg. In the production practice, people in Japan and Japan have profoundly realized that the development of hybrid rice is a major measure to promote the steady and steady growth of grain. At present, the production of hybrid rice has reached a high level, to further enhance its potential yield, although the difficulty is large, but is likely. Throughout the deepening hybrid rice technology, in our province should grasp the following main points:
