Yield performance: From 2003 to 2005, it participated in and passed the seventh-cycle summer soybean regional trial in Guangxi, with a three-year average yield of 139.16 kg per mu, an increase of 6.4% over the control Guixia No. 1.

Key cultivation techniques: For pure stands, the density per mu should be 13,000-18,000 plants, and for intercropping or relay intercropping about 10,000 plants per mu is suitable. Cultivate and weed, earth up, and apply seedling fertilizer as a topdressing: generally apply 5 kg urea + 10 kg potassium chloride per mu, or 5 kg urea + 15 kg compound fertilizer. If plant growth is poor, apply another topdressing at the flowering and podding stage.

Approval opinion: After review, this variety meets the Guangxi soybean variety approval standards and has passed approval. It can be planted as a summer soybean throughout the region.
