1. Selecting ginger seeds to promote early growth: Choose old ginger with full ginger pieces, bright skin color, fresh and tender meat, hard texture, 1 ~ 2 strong buds, 50-75g weight and no disease as the planting ginger. Soak ginger in 500 times solution of 50% carbendazim for disinfection before sowing. After disinfection, ginger should be aired for 2-3 days. When the surface of ginger is shiny, it can be piled up, covered with straw and germinated at a temperature of 20-25℃. When the ginger buds grow to 1 cm, they can be planted.

2, timely sowing, reasonable close planting: good irrigation conditions, high temperature, no germination, sowing in the shocking season; Without irrigation conditions and low temperature, it is necessary to accelerate germination, and sow in Tomb-Sweeping Day or Grain Rain season. Rake and ditch to make a high and narrow compartment with a width of 1.2m and a width of 30cm. Three planting ditches are evenly arranged in each compartment. After the decomposed base fertilizer is applied and mixed with the soil, it is planted and cultivated according to the plant spacing of 15- 18cm, and the soil is covered by 7- 10cm. 8000-9000 plants can be planted per mu. This method can enhance soil permeability, raise soil temperature, and prevent water accumulation and root rot in areas with flat terrain and high groundwater level.
