2 Choose seeds. Ginger varieties will be different in the north and south, so it is necessary to choose suitable seeds to grow ginger according to local planting habits. Select fine varieties of high-quality ginger slices as seeds, and the selected ginger seeds must have full bud eyes, no diseases and insect pests, and no rotten ginger. There are two strong ginger buds on each ginger. Generally speaking, the bigger the ginger, the better the yield. In order to save seeds, it is best to prepare ginger seeds and cut them with a knife. Seed wounds can be wrapped with fresh plant ash or lime powder. Sun-dry the selected ginger seeds, then soak them in 800 times solution and gibberellin aqueous solution, or soak them in Bordeaux aqueous solution for about 15 minutes. Disinfect the seeds, take them out and put them in wet sand at about 25 degrees to keep them moist and promote germination. Ginger seeds can be covered with plastic film to keep moisture. Generally, ginger germinates after 6-8 days.
After planting, base fertilizer must be applied. Generally speaking, an acre of land uses an average of 3000 kilograms of organic fertilizer and 30 kilograms of potassium fertilizer. The first fertilization was when the ginger seedlings grew to 25 cm. In rural areas, feces are mixed with water, or 20 kilograms of urea is sprayed with water. When autumn is about to enter, the second fertilization will be carried out in early September. The main purpose of this period is to make tubers grow. Fertilizer is mainly compound fertilizer and potash fertilizer, and the fertilizer application amount is 45 kg and 30 kg respectively. The last fertilization is performed when the tuber is slightly thicker than the third thumb, that is, one month after the second fertilization.
Observe the growth of ginger regularly, and deal with diseases and insect pests with special drugs in time.
