Abstract:

Taking ‘Bairizi’ radish as test material, the effects of 25 different plant and row spacing treatments on the main agronomic traits, yield, and quality of ‘Bairizi’ radish were studied to screen out the suitable plant and row spacing, and lay a foundation for the high yield and quality planting of ‘Bairizi’ radish. The results showed that with the increase of planting row spacing, the transverse diameter, fleshy root weight, and lignin content of ‘Bairizi’ radish showed an increasing trend; the vitamin C content showed an ‘S’ type increasing trend; the yield, finished product ratio, and soluble protein content showed an increasing trend first and then decreasing trend, and the skin thickness showed a decreasing trend first and then increasing trend. It was found that compared with single plant and row spacing planting, suitable plant and row spacing configuration could significantly improve the quality of ' Bairizi ' radish. Under the treatment of 30 cm large row spacing + 12 cm small row spacing + 15 cm plant spacing, the yield, finished product ratio, and soluble solid content of ‘Bairizi’ radish were the highest; the lignin, vitamin C, and soluble protein contents were moderate, and the sensory score was high. The plant spacing arrangement of 30 cm large row spacing + 12 cm small row spacing + 15 cm plant spacing was a more reasonable planting method for ‘Bairizi’ radish.
