“Sudou 9”is a new variety improved through the sexual hybridization in Donghai County Agricultural Science Research Institute, pedigree method applied. This variety has the following character early maturity, high yield, high quality, lodging resistance, disease resistance, strong adverse-resistance, wide adaptability, etc. Having participated in the experiment planting in Jiangsu Province from 2008 to 2010, it had an average yield of 184.8 kg / 667m 2, with a 3.6% increase over Xu dou 13. Its production increased significantly in 2010. The average yield in 2011 was 177.5 kg/667m 2, with a 6.7% increase over Xudou 13. In March 2012, it was examined and approved by Jiangsu Provincial Agricultural Variety Examination and Approval Committee, suitable for summer soybean planting in Huaibei area, Jiangsu Province. To explore suitable sowing date, the best planting density and reasonable fertilizer rate, cultivation experiments were made. The result showed that the best sowing period is early to mid-June, the sooner the better in this scope. The best density is 14000 plants / 667m 2, with an advisable basal manure amount of 20 kg/667m 2 of 45% compound fertilizer containing nitrogen, phosphorus and potassium.
