Abstract:

To achieve efficient radish production based on the integration of agricultural machinery and agronomy in the Liupan Mountain area of Ningxia, this study took Chunguan Qingcui No. 2 as the test material, with different powder ridge depths (20, 30, 40 cm), sowing methods(traditional manual sowing, seed rope sowing, and air suction sowing), and sowing depths (1.5, 2.0, 2.5 cm) as experimental factors. A three-factor, three-level quadratic regression orthogonal experiment was designed to analyze the effects of different factors on the comprehensive index of soil environment, radish germination rate and yield. The results showed that among all factors, sowing depth had a significant effect at p<0.01 level on both the comprehensive index of soil environment and radish yield, sowing method exerted a significant effect at p<0.01 level on the comprehensive index of soil environment, and yield and germination rate of radish, powder ridge depth had a significant effect at p<0.01 level on the germination rate of radish. The interaction between powder ridge depth and sowing depth, as well as the interaction between powder ridge depth and sowing method, had significant effects at p<0.05 level on the comprehensive index of soil environment, yield, and germination rate of radish. However, the interaction between sowing depth and sowing method had no significant effect on these indicators. Through comprehensive analysis, the optimal parameter combination was determined as follows: powder ridge depth of 30 cm, seed rope sowing, and sowing depth of 2.0 cm. Under this combination, the comprehensive index of soil environment was 14.91, the germination rate of radish was 92.13%, and the yield of radish was 81.15 t·hm-2. The results of this study can provide a reference for improving local radish yield and promoting the standardized, mechanized, and efficient development of the radish industry.
