水稻三系杂种配制成功在生产上应用,这是我国农业科学技术的一项重大成果。如何充分运用此项成果为农业生产服务,是需要探讨的一个课题。1976年我省大面积试种三系杂种(下称杂优稻),其效果在不同地区、不同造别间是有差异的,究竟增产效果怎样?优势有多大?发展前途如何?应作研究。为此,我们对1976年我省试种杂优稻的情况进行了调查,现把材料整理分析如下。
Three-line hybrid rice preparation in the successful application of production, which is China’s agricultural science and technology a major achievement. How to make full use of this achievement to serve agricultural production is an issue to be explored. In 1976, a large area of our province planted three-line hybrids (hereinafter referred to as “gifted rice”) with different effects in different regions and different establishments. What is the effect of increasing yield, what is the advantage and what is the development prospect? . For this reason, we conducted a survey on the trial of hybrid rice in 1976 in our province. Now we analyze the materials as follows.
