Abstract:
The paper discusses the techniques of mechanical sowing and fertilization for sugarbeet by layers. With the use of this techniques in the some condition, the growing force in the early growing stages of sugarbeet obviously increases. Compared with sugarbeet seeds of which are mixed with fertilisers, when seeded, plant height, leaf number, leaf area and LAI of this kind of sugarbeet all increase. The variation coefficients of plant distance for the sugarbeet much less than that of the drilling sugarbeet. The yield increases over 15%, and the sugar content slightly increases.
Key words:
