High-yield planting technology of ginger

As a very important seasoning, raw vegetables play a key role both in home kitchens and hotel restaurants. At the same time, it can also be eaten alone as a vegetable and has important medicinal value. Ginger's spicy taste and unique aroma can be incorporated into dishes to make them taste more delicious and rich. Let’s learn about the high-yield cultivation technology of ginger.

1. Site selection and fertilization

The root system of ginger is relatively fragile, so it is suitable to be planted in areas with deep soil, good water retention and air permeability, and convenient drainage and irrigation. It is required to deep plow 25-30 cm in winter and then repeatedly harrow before sowing. When making the ridges, more than 5,000 kg of farmyard manure and poultry manure were applied as base fertilizer. Ginger fields should be rotated every 2-5 years.

2. Seed selection and germination

Choose ginger that is plump, unscathed, yellow, and free of pests and diseases and is harvested before the frost of the previous year and stored in the winter as seeds. One month before sowing, place the selected ginger seeds in a sunny place to dry, turn them over once at noon every day, move them indoors in the afternoon, stack them for 3-4 days, and then dry them again. Repeat this 3-5 times. There are three methods for germination: first, hang the ginger seeds on the stove and smoke them with firewood; second, surround the ginger seeds with fermented cow and pig manure, cover them with a film, and use the temperature of the cow and pig manure (25-28 degrees) to germinate; third, cover the ginger seeds with a quilt or film and keep the temperature at 23-25 ​​degrees. When the ginger sprouts grow to 1 cm, take them out and divide them into small pieces of about 50 grams, keep one strong sprout and cut off the rest. If you find too much shredded ginger or ginger pieces with red circles, do not use them. When breaking ginger, if you find that the young sprouts turn black and change color, they must be removed.

3. Sow seeds at the right time

When the local temperature stabilizes at around 12-15 degrees, it is time to sow seeds, usually between Qingming and Guyu. The ridges are laid in an east-west direction with a row spacing of 50-55 cm and a plant spacing of 20-23 cm. 220-250 kg of ginger seeds are required per mu. When sowing, the ginger sprouts should face south with the buds upwards, and then be covered with soil, fertilizer and wood ash to a thickness of about 3 cm, spray with herbicide , and then cover with film. Water 3-4 days after sowing. In order to block the sunlight, soybeans are planted at the bottom of each row of furrows and increase income at the same time.

4. Field management

When the seedlings are 7-10 cm tall, apply fertilizer to promote seedling growth, and apply 30 kg of compound fertilizer per mu. After 15 days, apply seedling-strengthening fertilizer, 40 kg of fermented soybean meal fertilizer per mu. Apply seedling-promoting fertilizer around the summer solstice, with 40 kg of urea per mu. Apply fertilizer according to the condition of the seedlings during the Great Heat and the End of Heat. Before and after planting, when the seedlings are 13-17 cm tall and have 1-2 tillers, the soybeans are growing tall enough to be shaded. Around the beginning of summer, soybeans should be harvested immediately after they mature. Dig out the mother ginger, hoe shallowly, remove the tillers, and keep one strong seedling for each ginger seed. Then apply 50 kg of compound fertilizer, build up hard soil about 20 cm high, and irrigate according to the dryness and wetness of the ground. 4-5 days before the beginning of autumn, remove the tops of the ginger plants in the morning before the dew dries up, and do so every other week thereafter.

The main disease of ginger is ginger blight, also known as rot disease. Prevention methods include: avoiding waterlogging in the ginger field, using mature farmyard manure, treating ginger seeds with Bordeaux mixture or carbendazim for 10 minutes before sowing, and spraying with 600 times diluted 50% Mancozeb or 1000 times diluted 50% Mancozeb in the early stage of the disease. Ginger borer, also known as heart borer, causes the stems and leaves of ginger to gradually turn yellow and die. The prevention and control method is: use 1.5-2 kg of 2.5% dichlorvos powder per mu, mix it with 45-60 kg of fine soil, and spread it in the field before the dew dries. Can be captured manually if necessary.

5. Watering

Ginger enters its vigorous growth period and water consumption increases. At this time, water should be applied every 7-10 days to keep the ground moist. Watering can also lower ground temperature. Watering should be done in the morning and evening, avoiding the high temperature period at noon.

6. Harvest

Ginger is not cold-resistant and should be harvested before the frost in mid-to-late October. Water 3-5 days before harvest to make the soil moist for easy digging. After harvesting, the above-ground stems are cut off from the base of the stems and can be stored without drying. The storage temperature is controlled at around 15 degrees and the humidity is maintained at around 65%. Make sure the ginger is stored at a constant temperature and harvested before frost to protect it from freezing.

The above is an introduction to the key points of high-yield ginger cultivation techniques. As a common condiment , ginger has always had a relatively large market demand, but if you want to achieve high yields, it is important to learn comprehensive cultivation techniques.
