Abstract

Abstract: To investigate the lodging resistance and appropriate planting density, increase yield of tartary buckwheat, the‘Xiqiao 1’cultivar was used to evaluate the effect of different planting densities on stem characteristics, lodging resistance and yield of tartary buckwheat. Results showed that different planting densities significantly effected characters of stem and root. With the increasing of planting density, the light transmittance, the main root length, number of first lateral root and root volume decreased, the plant height, internode length and lodging rate increased, but the yield displayed an acceleration first and then deceleration. The correlation analysis indicated that the characters of stem and root were intimately correlated with plant resistance to lodging. The plant height and internode length were significantly negatively correlated with stem breaking strength, but positively correlated with lodging rate. Therefore, appropriate planting density (9×10⁵-12×10⁵ plant/hm²) reduced the lodging rate, improved the resistance to lodging and increased the population yield, and it deserve applying extends.
