The seeds of the whole ginger planted in the sun were planted on a sunny day in a leeward, sunny, dry and warm place. It is rolled out every day from 8 to 9 am and recovered at 4 to 5 pm. The next day when the sun is noon, the ginger seeds are turned one at a time and continuously dried for 3 to 5 days. The ginger seeds are dry, white, and slightly wrinkled, indicating that the sun has dried.
Germination was performed after germination. Germination can promote germination of young ginger buds as soon as possible, and the emergence of seedlings is fast and orderly, which is a very important technical measure. Regardless of the germination method, ginger must first be preheated. That is, on the last day of ginger drying, ginger seeds should be collected and collected in the afternoon, placed in the room for 3 to 4 days, and the hay is placed on the lid. Grass curtains, keeping the temperature at 11°C～16°C, promote the transformation and decomposition of nutrients in the ginger, and then move to the germination site for germination. There are two commonly used germination methods. One is impotence germination. Yangshuo is going to dig in the sunny windward area, east-west direction, depth 60 cm, width 1 to 1.2 meters, depending on how much the length of ginger. The bottom of the bed is 10 cm thick wheat straw. Put a ginger seed one by one, put the buds upward on the wheat straw, and then spread a layer of 15 cm thick straw. Cover it with a plastic film and cover the grass at night. During germination, the starting temperature should be maintained at about 20°C, then gradually increased to 28°C, and the maximum should not exceed 30°C; the humidity should be maintained at 75% to 80%. After 7 to 8 days, when the ginger buds sprouted and expanded, they began to release air and gradually cooled to 20°C. In this way, the young shoots elicited under the condition of variable temperature were hypertrophied and robust. After 20 to 25 days, the ginger shoots can be sown when 0.5 cm long. The second is the greenhouse germination. After the sun-dried ginger seeds are piled in the greenhouse by referring to the above method, the same plastic film is covered on the top, the humidity and the temperature are controlled to be positive, and the ginger buds can be released after about 20 days.
After the stalks of ginger buds are released, the whole block is first selected and then the buds are picked. Must use fat ginger, disable lean ginger. 0.5 kilograms of whole ginger, 10 to 12 kang, is appropriate, leaving only one strong bud per piece. In general, before the beginning of summer in the valley after the rain, when the 5 cm ground temperature is stable above 15°C, it can be planted.
