我省杂交水稻常年种植面积在1000万亩左右,制种面积7～8万亩,生产种子1200万kg上下,由于制种过程中层层严格把关。因此,我省的杂交水稻种子质量特别是种子纯度在全国享有较高声誉。但从抽检的情况看,种子发芽率和净度的合格率还不尽人意,本文针对我省种子的质量现状进行分析,找出存在问题的原因,寻求解决的对策措施,以提高种子质量。 The perennial planting area of ​​hybrid rice in our province is about 10 million mu and the seed production area is 7-8 million mu. The production of seeds is about 12 million kg. Due to the strict control of layers during the seed production process, Therefore, the quality of hybrid rice seeds in our province, especially the purity of seeds, enjoys a high reputation throughout the country. However, from the sampling situation, the seed germination rate and the purity of the pass rate is not satisfactory, this paper analyzes the quality of seeds in our province to find out the reasons for the problems, to find solutions to improve seed quality.
