为了摸索杂交水稻春播夏制高产的规律,认真总结经验教训,进一步挖掘制种的潜力,1980～1982年,我们结合高产县的经验,对杂交水稻春播夏制的几个主要技术问题,进行了调查、分析,并形成了一些看法,现提出来与大家共同商讨。一、关于提高种子纯度、保证种子质量问题种子的纯度是关系到杂交水稻命运和前途的大问题。几年来,我区在杂交水稻“三系”生产中,由于对“在保纯中发展,在提纯中提高”注意不够,杂株
In order to explore the law of high-yielding hybrid rice spring sowing summer, earnestly sum up experiences and lessons to further tap the potential of seed production, from 1980 to 1982, we combined with the experience of high-yielding hybrid rice spring sowing of several major technical issues were carried out Investigation, analysis, and formed a number of views, are put forward to discuss with everyone. First, on improving the purity of the seed to ensure the quality of the seed The purity of the seed is related to the fate and future of hybrid rice big problem. Over the past few years, our district in the “three lines” of hybrid rice production, due to the “development in the pure, purification to improve” attention is not enough,
