Planting time of ginger

Sow before and after Tomb-Sweeping Day or in Grain Rain. The sowing row spacing is 35-40 cm, the plant spacing is 26-30 cm, the ditch depth is 10-20 cm, and the seeds used per mu are about 500 kg.

Sowing method:

Use 1, 15 kg urea and 25 kg compound fertilizer as seed fertilizer per mu, and put the fertilizer into the ditch and mix it evenly with the soil.

2. Pour bottom water about 1 hour before sowing to make the soil moist.

3. Put the ginger slices horizontally in the ditch, keep the buds in the same direction, gently press them into the mud by hand, and cover them with wet fine soil, about 5 cm.

Precautions:

Ginger is a shade-loving plant, which is not resistant to high temperature and strong light. It should be shaded in summer to promote growth.

Ginger is neither drought-tolerant nor waterlogging-tolerant, and has strict requirements on water content. It is wise to keep the soil moist during the growing period. During the high temperature in summer, it is best to water it in time, especially in the morning and evening. In rainy days, the accumulated water in the field should be removed in time to reduce the occurrence of ginger plague. In order to prevent the roots from sticking out of the ground, the epidermis from thickening and the quality from getting worse, it is necessary to cultivate the soil. Generally, it is combined with watering and fertilization for 2-3 times, about 3 cm each time.

The main diseases are rot and spot disease. Rot disease generally begins in July and peaks in August-September. When the diseased plants are found, they should be pulled out in time, the soil with germs should be dug out, lime should be sprinkled in the diseased holes, and clean sterile soil should be used for landfill. Spraying 50% chlorothalonil solution 800 times at the initial stage of spot disease, and spraying every 7 ~ 10 days/time. The main pests are ginger moth and ginger maggot, and trichlorfon or phoxim is sprayed on the leaves for control.

The underground rhizome of Dioscorea zingiberensis is usually excavated after the plants wither completely in autumn and winter, and the best harvesting period is from the end of/kloc-0 to the middle of February, and the rhizome is usually excavated every 2 to 3 years.
