Requirements for growth conditions of ginger

Jiang is native to tropical rainy forest areas and requires a wet and warm environment. The suitable temperature during the growth period is 22-28 ℃. It is not resistant to cold, and the aboveground parts die from frost. The underground part can not stand the low temperature of 0 ℃. Also not heat-resistant, such as the temperature is too high, direct sunlight, growth is blocked, so the cultivation should be shaded in summer. Strict requirements for soil moisture, drought resistance is not strong, such as long-term drought, stems and leaves withered, ginger can not be expanded, but if too much Rain Water, poor drainage in the field, will cause excessive growth and ginger rot. The requirements of ginger for nitrogen, phosphorus and potassium fertilizer: potassium is the most, nitrogen is the second, and phosphorus is the least. The required nutrients are not only supplied by base fertilizer, but also need topdressing. Nitrogen fertilizer is the main fertilizer in seedling stage, and organic fertilizer or compound fertilizer containing nitrogen, phosphorus and potassium is needed in the period of rapid expansion of ginger. Ginger bogey continuous cropping. Cultivated in loam or clay loam with more humus, the yield is higher, but the pungent taste is light and the tissue is tender, so it is suitable for collecting tender ginger for vegetable use. If cultivated in sandy loam with less humus, the yield is lower, but it is spicy and spicy, so it is suitable for growing ginger or making ginger powder.
