1、 Curing method

1. Soil: Kaempferia like to grow in mild, humid and water friendly soil. Loose and fertile sandy soil is generally the best

2. Moisture: it likes to be wet. After planting, it should be watered in time to wet the soil layer. However, there should be no ponding, and drainage and waterlogging should be carried out in order to make it grow better

3. Nutrients: before planting, sprinkle some phosphate fertilizer on the soil in the soil layer, and then turn over the whole soil layer. After planting, it can absorb nutrients better

4. Light: like the place with sufficient and mild light, and sufficient light makes its branches and leaves vigorous and strong. However, in summer, the light cannot be strong, and the strong light can sunburn its branches and leaves

2、 Breeding skills

1. Pruning: the withered and yellow branches and leaves shall be cut off from time to time, and the cut branches and leaves shall be removed to avoid absorbing nutrients from the soil, so as to prevent the growth of other branches and leaves from being hindered

2. Reproduction: Shannai generally selects tubers for reproduction, selects strong tubers and air them, and selects dry places for indoor storage. Then plant the tubers in nutrient soil and spray some water. In about seven days, you will see small buds grow

3、 Diagnosis and treatment problems

1. Leaf spot: leaf spot usually occurs after planting, which can be avoided under the protection of planting. Spray some antibacterial agents in the soil layer, and timely discharge the accumulated water when there is rain can be avoided

2. Rodent damage: kaempferi is easy to cause rodent damage, especially at night. Rats will come out and eat kaempferi and its roots. At this time, you can put some mouse clips, sticky stickers and rat poison in the field to trap and kill the rats. After the trapping and killing, you should clean up the rats in time to avoid the rats rotting in the ground and affecting the growth of Shannai

4、 Other issues

1. How to spend the winter: dry it in the air in winter and store it indoors in a dry place. When storing, first spread a layer of sand on the ground and then place it on the ground. In this way, the storage time will be longer

2. Edible or not: Shannai is edible. The tuber of Shannai is Shajiang, which can be used as seasoning
