Abstract
Effects of spraying leaves with a boron fertilizer solution of varied concentrations on the growth of roots and plant as well as the productivity of a low-yield Liuku 2081 tartary buckwheat were studied.With the spraying, the contents of ammonium nutrients and organic matters in the rhizosphere soil significantly decreased, while those of available phosphorus and potassium as well as the total length, surface area, volume and mean diameter of the roots and the plant yield increased significantly.At the applied boron concentration of 24 mg·L-1, the tartary buckwheat yield peaked to nearly double that of control.Significant correlations were observed between the length and the surface area and volume of the roots, between the surface area and the volume of the roots, and between the counts of the main stems and the branches on the plant.
