Abstract

Abstract:

In order to explore the suitable planting environment and density of fruit radish, this study took fruit radish as the test object, and considered two factors of planting environment and planting density. Under the maximum recommended planting density of 111110 plants/hm², three planting environments, thick earth wall solar greenhouse, arch shed and open field, were marked as R₁, G₁ and L₁, respectively. Three planting densities of 111110, 55555 and 27777 plants/hm² were set under open-air planting conditions, which were marked as L₁, L₂ and L₃, respectively. The growth, yield and quality of fruit radish were investigated. The results showed that under different planting environments, compared with L₁, the leaf area, leaf fresh and dry weight, root fresh and dry weight, yield and soluble sugar content of R₁ and G₁ treatments increased, while the contents of soluble solids and vitamin C decreased. The root fresh and dry weight, yield and soluble sugar content of G₁ treatment were the highest, which were 924 g, 28.8 g, 102.67 t/hm² and 3.34%, respectively, and increased by 52.98%, 43.95%, 52.99% and 16.38%, respectively, compared with L₁. Under open-air planting conditions, with the increase of planting density, leaf area, fresh and dry weight of leaves, yield and soluble sugar content increased first and then decreased, vitamin C decreased, and soluble solids content decreased first and then increased. The yield and soluble sugar content of L₂ treatment were the highest, which were 93.55 t/hm² and 3.64%, respectively. The yield were 39.4% and 99.04% higher than those of L₁ and L₃ treatment, respectively, and soluble sugar content increased by 26.83% and 7.06%, respectively. In summary, the fruit green radish grows best under the arch shed planting, and the suitable field planting density is 55555 plants/hm².
