Effects of Different Ridge and Planting Distances on the Yield of Eshu No.9

The experiments on the combination of different ridge and spacing distances of Eshu No.9 were conducted to explore the optimal ridge and spacing distance. The results showed that the yields of different ridge and spacing distance were significantly different. The optimal combination of ridge and spacing distance of Eshu No.9 in Xianning city were 80 cm and21 cm respectively, and the yield could reach 42 828.1 kg / hm2.
