该文选用5个特种稻品种分期播种，分析气候因子对其产量性状和色素含量的影响，结果表明：结实率、单株产量、每穗粒数等产量性状和色素含量都显著或极显著地受到播期影响；多数特种稻品种作晚稻种植可提高产量，改善外观品质，提高经济效益。
In this paper, five special rice varieties were sown in stages to analyze the effects of climatic factors on their yield traits and pigment contents. The results showed that the yield traits and pigment contents such as seed setting rate, yield per plant, grain number per spike were all significantly or extremely significantly Affected by sowing date; most special rice varieties for late rice planting can increase yield, improve the appearance of quality, improve economic efficiency.
