Ginger is a common seasoning vegetable used in people's lives. Its main varieties include young ginger, old ginger, sand ginger, yellow ginger, etc. The ginger planting area in China is also quite extensive. Let's learn how to grow ginger together.
1. Ginger seed treatment
To plant ginger, first select healthy ginger pieces with 1-2 small buds as ginger seeds. Then soak them in a solution of fungicide to disinfect the wounds. After soaking, take out the ginger seeds and place them in a germination box to promote germination and encourage the growth of strong buds.
2. Planting time
Ginger prefers a warm and humid environment and loose, fertile soil. It is usually planted from the end of April to the beginning of May each year. It has poor cold resistance and the optimal growth temperature is 25℃.
3. Apply base fertilizer by digging trenches
Generally, the ginger furrows should be prepared a month in advance, with a furrow spacing (row spacing) of 65-70 cm, usually around 67 cm. Before planting ginger, a base fertilizer should be applied to the bottom of the furrows. This base fertilizer mainly consists of compound fertilizer and organic fertilizer .
4. Apply fertilizer appropriately
When ginger seedlings reach 25 cm in height, the first top dressing can be applied by spraying a solution of urea diluted in water. The second top dressing should be applied in early September when the ginger tubers are developing, primarily using compound fertilizer plus potassium fertilizer. This second top dressing aims to promote rapid tuber enlargement. The final top dressing should be applied one month after the second top dressing, using the same fertilizer but halved, also to further promote tuber development.
5. Pest and disease control
Ginger is susceptible to diseases and pests such as rot, spot disease, ginger borer, and ginger maggots, all of which can affect its growth and yield. Summer is the peak season for these diseases and pests. When diseased plants are discovered, they and the surrounding soil should be removed promptly, and quicklime should be applied to the soil to prevent the spread of pathogens. Pesticides should also be sprayed in a timely manner.
