Abstract
The relationship between temperature change and days of sugarbeet seedling emergence was studied by 5 different sowing date treatments under a natural condition in Harbin area. The results showed that: The earlier sowing date, the sooner seedling emergence of sugarbeet, and the days of sugarbeet seedling emergence were decreasing with delaying the sowing date. For seedling germination rate was as treatment1 treatment2 treatment3 treatment4 treatment5. The seedling germination rate of earlier sowing date was better than that of latter sowing date. With delaying the sowing date, the average daily temperature and days of sugarbeet seedling emergence presented power function equation(y =251.1723x-1.3093), the average soil temperature and days of sugarbeet seedling emergence presented exponential equation(y=57.5499e-0.1624x'). The equations could predict the days of seedling emergence with average daily temperature or soil temperature, and provide indicator basis for choosing suitable sowing date and for cultivation of sugarbeet.
