2. Ginger likes warm and humid environmental conditions and is not resistant to low temperature frost. Germination begins above 16℃, the suitable temperature for seedling growth is 20-25℃, the suitable temperature for stem and leaf growth is 25-28℃, and the growth stops below 15℃. Therefore, the planting time of ginger is generally from late April to early May, and mid-March is suitable for low-heat valley areas. It can be cultivated by accelerating germination or using plastic film.

3. Temperature: Ginger is native to tropical China and East Indies, and likes temperature. The growth of roots (ginger slices) needs high temperature. It can germinate above 16 ~ 18℃, and ginger grows rapidly at 20 ~ 27℃. The average monthly temperature is 24 ~ 29℃, which is most suitable for rhizome meristem growth. When the temperature is lower than 15℃, the growth will stop, and when it reaches 40℃, the germination will not be hindered. However, below 10℃, ginger pieces are easy to rot.

4, light: ginger is resistant to shade but not to strong sunshine, and the requirements for the length of sunshine are not strict. Therefore, when planting, we should build a shade shed or use intercropping crops for proper shade to avoid strong sunlight.

5. Moisture: The root system of ginger is underdeveloped, and its drought resistance and waterlogging tolerance are poor, so the requirements for moisture are particularly particular. Too dry or too wet soil during the growing period is not conducive to the growth and expansion of ginger slices, and it is easy to cause diseases and rot.

6. Soil nutrition: Ginger likes fertile and loose loam or sandy loam, and it does not grow well in low-lying areas with heavy viscosity and high water content, and does not grow well in poor land with poor water retention. Ginger needs potassium fertilizer the most, followed by nitrogen fertilizer and phosphorus fertilizer the least.
