对晚籼稻的同一品种在不同年份(即纵向数据)和不同品种在同一年份(即横向数据)的全生育期与产量的关系进行研究,得出早熟品种的纵向数据与横向数据的的分析结果一致,当全生育期为110.1~115.7天时,产量随着全生育期的延长而递减;中迟熟品种的纵向数据与横向数据的的分析结果也一致,当全生育期为115.5~120.7天时,产量随着全生育期的延长而递增。在应用上,要选用最佳生育期的晚籼稻品种,以夺取稳产和高产。
The relationship between yield and yield of the same variety of late indica rice in different years (ie, longitudinal data) and different varieties in the same year (ie, horizontal data) was studied, and the analysis results of longitudinal data and lateral data of early maturing varieties The results showed that when the whole growth period was 110.1-115.7 days, the yield decreased with the extension of the whole growth period. The analysis results of the longitudinal data and horizontal data of the middle-late maturing varieties were also consistent. When the full-growth period was 115.5-120.7 days, Yield increases with full-term growth. In the application, to choose the best growing season indica rice varieties, in order to seize stable and high yield.
