Rapid and Efficient Softening Cultivation Techniques for Ginger Sprouts

Edible Gardening 0 views
In recent years, we have achieved success in cultivating softened ginger sprouts by adopting measures such as keeping them indoors away from light and controlling temperature and humidity. This method has a short production cycle; the sprouts can be harvested 40 to 45 days after the ginger seed is placed in the bed. Moreover, as long as temperature, humidity and ventilation are kept within suitable ranges, production can be carried out all year round. The rapid and efficient cultivation techniques for softened ginger sprouts are described below: 1. Seed selection Select white-fleshed ginger seeds with a high sprouting rate, plump buds, suitable size, good color and no pests or diseases. To increase the sprouting rate, it is best to divide the whole piece of ginger by each bud and sow them separately. According to trials

In recent years, we have achieved success in cultivating softened ginger sprouts by adopting measures such as keeping them indoors away from light and controlling temperature and humidity. This method has a short production cycle; the sprouts can be harvested 40 to 45 days after the ginger seed is placed in the bed. Moreover, as long as temperature, humidity and ventilation are kept within suitable ranges, production can be carried out all year round. The rapid and efficient cultivation techniques for softened ginger sprouts are described below:

1. Seed selection Select white-fleshed ginger seeds with a high sprouting rate, plump buds, suitable size, good color and no pests or diseases. To increase the sprouting rate, it is best to divide the whole piece of ginger by each bud and sow them separately. According to trials, with this sowing method, each kilogram of ginger seed can produce more than 32 sprouts.

2. Sprout promotion Immediately dip the ginger pieces separated by bud in a layer of plant ash for disinfection, then choose a sunny day to dry them in the sun for 1 to 2 days, turning them 1 to 2 times. Then stack the ginger seeds indoors (generally the stack height should not exceed 10 cm), spray an appropriate amount of water, and cover with fine sand, etc., to keep warm and moist. Keep the temperature inside the stack at around 25°C. Once most of the ginger has sprouted but has not yet rooted, it can be sown.

3. Seed arrangement Arrange cement boards with a layer spacing of 50 cm, and build a surrounding wall with bricks as the base bed. Use fertile fine sand with good moisture retention as the bed soil. Spread a 4 to 5 cm thick layer of fine sand on the bottom of the bed and level it, then arrange the ginger seeds neatly with the buds facing up, generally 20 to 25 kg of ginger seeds per square meter. After arranging the ginger seeds, cover with a 5 cm thick layer of fine sand.

4. Watering Water immediately after planting the ginger seeds, with the amount of water sufficient to soak through the sandy soil of the sprouting bed. When most of the ginger sprouts emerge, based on the dryness and moisture of the bed soil, water a second time, with the amount of water sufficient to soak through the sandy soil. In short, throughout the entire growth period, the bed soil must be kept moist but not waterlogged, and the indoor air humidity should be kept at 80% to 90%. In addition, after watering, be sure to use fine sandy soil to thoroughly cover the ginger pieces exposed on the sand around the edges and on top of the sprouting bed, and the thickness of the fine sand above the ginger seeds should not be less than 5 cm.

5. Temperature regulation The suitable temperature for ginger sprout growth is 23 to 30°C. To promote more sprouting and faster sprouting, before the ginger sprouts emerge, the bed temperature should be kept at 25 to 28°C; after the ginger sprouts emerge, keep it at 28 to 30°C before the seedlings are 30 cm tall, and thereafter keep it at around 25°C. When the temperature is low, add film, straw or other coverings to increase warmth; when the temperature is high, take measures such as opening doors and windows and spraying water on the ground and into the air to lower the temperature.

6. Harvesting Generally, harvesting is most suitable 40 to 45 days after the ginger seeds are placed in the bed, when the sprout seedlings are about 30 cm tall. Harvesting method: use a short-handled iron shovel to take out the ginger pieces, then snap off the sprout seedlings from the ginger pieces.

7. Processing Remove the fibrous roots from each snapped-off ginger sprout one by one, then cut off the top sprout portion beyond 30 cm of the ginger sprout seedling. Finally, wash the soil off the ginger sprout seedlings, use a cylindrical ring cutter with a diameter of 1 cm to encircle the ginger sprout seedling and rotate the cutter to cut off the ginger sprout seedling, making a semi-finished product with a rhizome diameter of 1 cm and a length of 2.5 cm. After pickling in acetic acid brine, it becomes the finished product.
