杂交水稻是建国以来我国南方水稻生产继单改双、高改矮之后的又一次重大改革。但是,我省目前杂交稻的发展速度不很平衡,而且各地增产幅度也不一。究其原因,虽然是多方面的,但其中一个重要原因是气候适应性没解决好。所以,如何根据我省各地的气侯特点,采取相应的适应性措施,趋利避害,使杂交优势得以更好地发挥,增产效益更为明显,达到高产稳产,是一个需要研究的问题。 Hybrid rice is another major reform since the founding of the People’s Republic of China. However, at present, the development speed of hybrid rice in our province is not very balanced, and the yield of hybrid rice in different areas is also different. The reason for this is that although it is multifaceted, one of the important reasons is that climate adaptation has not been solved well. Therefore, according to the characteristics of climate in different parts of our province, it is necessary to adopt corresponding adaptive measures to reduce risks and gain advantages in hybridization so that the yield advantage is more obvious and high and stable.
