Soil cultivation is an important measure to determine the yield and quality of ginger. The soil is suitable for the growth of ginger and the high yield. The roots of ginger need to grow in a dark, humid environment, and stop growing when they see light. Therefore, the soil should be cultivated with the growth of ginger. If the soil is not timely, the roots of ginger are exposed to the air, which will seriously affect the quality and yield of ginger.

For the cultivation of ginger, it should be adapted to local conditions, and it is appropriate to use soil for 3 times.

For the first time, the soil had 3 to 5 tillers in the roots of ginger, but it started when it was not exposed to the surface. The soil was about 2 cm thick. At this time, only use a small pot or hook and other agricultural tools, and the ridge soil (usually ridge width 25~30 cm) on both sides of the ginger planting ditch is drawn down the ridge to the planting ditch and watered. This not only prevents the growth of weeds, but also facilitates the expansion of the roots of ginger. The first soil should not be too thick, otherwise it will easily affect the permeability of the soil, causing the growth of ginger sprouts to be blocked, the tillering of roots and stems, the growth slow, and the yield and quality are affected.

The second soil should be carried out 20 days after the first soiling, and the soil thickness is 2~3 cm. At this time, the ridge soil on both sides of the ginger planting ditch can be placed into the ginger planting ditch with a small pot or a hook. The soil should not be too thick, otherwise it will easily cause the growth of ginger roots and affect the yield.

The third cultivation is also called “Da Pei”, which is carried out 15 days after the second cultivation, and the thickness is 7-8 cm. At this time, all the soil on the original ridge should be transplanted into the planting ditch, so that the original ditch of ginger grows into a ridge, and the original ridge becomes a ditch. This time, the cultivation of soil is very important and is the key to determining the growth and development of the roots of ginger. If the soil is shallow, the ginger is short and thick; if the soil is thick, the ginger is slender. Later, if ginger buds are found, they should be cultivated in time to ensure the normal growth of the roots of ginger.

Each time the soil is to be combined with fertilization and watering, it should be fertilized first and then soiled. Before the first and second soil cultivation, 5 kg of compound fertilizer and 40 kg of bio-organic fertilizer can be applied per acre, and the plant base should be applied at a distance of about 15 cm from the base of the plant. The compound fertilizer should not be applied to the base of the plant to avoid burning seedlings. After the application, soil and watering. The last time the soil should be fertilized, the amount of fertilization should be increased. At this time, it is the fastest growing period of ginger roots. It requires a large amount of fertilizer, and can apply 50 kg of compound fertilizer and 75 kg of bio-organic fertilizer per acre.
