1、 Planting time

Galangal is usually sown in spring, usually around the spring equinox or Qingming. The time should not be later than the beginning of summer, otherwise the high temperature will affect the seed germination, and it may rot due to diseases and pests

2、 Land selection

Shajiang is suitable for growing in soft and hydrophobic soil. It is drought resistant and barren resistant, so it does not require much soil fertility. If there is a certain base fertilizer in the soil, it is also conducive to its growth. The soil should not be too hard, otherwise it will affect seed germination. Before planting, loosen the soil, break up or throw away the large soil blocks

3、 Seed selection and sowing

Choose the seeds with appropriate size and relatively hard texture. Such seeds are more mature and the germination rate will be higher. It should be dried for a week after seed collection and 1-2 days before sowing, which can effectively promote germination. Plant the bud eyes of Shajiang on both sides and cover them with fine soil. If large areas are planted, the density should not be too large, but can be arranged in product shape

4、 Subsequent maintenance

In order to ensure the normal growth of seeds, moderate watering and fertilization are essential. Because it is afraid of moisture, it is only watered when it is dry. If the basin soil is too damp, ventilation is needed to accelerate water evaporation. It is easy to get sick in the seedling stage. A little compound fertilizer can be applied, and the amount of fertilizer should not be too much to prevent burning the root. When autumn enters the growth period, you can apply more phosphorus and potassium fertilizer and less nitrogen fertilizer
