Before and after the rain, it is the best season for ginger planting in the north. Doing a good job of preparations before planting is conducive to achieving a bumper harvest. The following introduces the preparation work that should be done before sowing ginger.
1. Sun-dried ginger
Take out the ginger seeds from the storage cellar 20 days before the suitable sowing period, wash off the soil on the ginger block with clean water, spread it flat on a straw mat or on a clean ground for 1 to 2 days, and put it indoors in the evening to prevent nighttime damage. freeze. Sun-dried ginger can increase the temperature of the ginger block and promote the decomposition of internal nutrients, thereby speeding up the germination speed and preventing the ginger block from rotting. After ginger seeds are air-dried for 1 to 2 days, they will be stacked indoors for 2 to 3 days, and grass curtains are covered on the ginger pile to promote nutrient decomposition.
Second, choose ginger species
When selecting seeds, you should choose healthy ginger blocks that are large, plump, bright in skin color, free from rot, unfrozen, hard in texture, and free from pests and diseases. Be sure to eliminate those thin and weak, brown and soft flesh. Sick ginger block.
Three, seedbed accelerating germination
It is often used for inducing germination in the yang border or in the greenhouse. Prepare a germination bed with 10 cm thick wheat straw on the bottom of the bed. Place the ginger seeds one by one with the bud eyes up on the wheat straw, and then spread a layer of 15 cm thick wet wheat straw, cover it with plastic film, and then cover the grass thatch at night. During the germination period, keep it at about 20°C, and then gradually increase to 28°C, and the highest should not exceed 30°C. The humidity should be maintained at 75% to 80%. After 7 to 8 days, when the ginger buds germinate and swell, they will start to release the air, and the temperature will gradually decrease to 20°C, so that the young buds that are urged under the condition of changing temperature will be enlarged and strong. When the ginger bud is 0.5 cm long, it is the suitable time for sowing.
Fourth, ginger seeds divided into pieces
After the ginger buds are ready, first select the whole piece, and then select the buds to break. A whole piece of ginger weighing 500 grams can be broken into 10 to 12 pieces, and it is better to leave 1 to 2 strong buds per piece. In the north, it can be planted after the rain and before the beginning of summer when the ground temperature of 5 cm is stable above 15 ℃.
