1, light to catch Miao Fei, re-apply to compose. Supplementary application of autumn fertilizer in combination with watering in mid-June, 25 kg of urea per mu along the water to promote the growth of ginger seedlings. In the middle and early July, the plastic film was removed and 50 kg of compound fertilizer was applied per mu. Until August 20th, apply 30 kg of potassium sulfate per mu, and timely water after top dressing. In mid-September, according to the growth of ginger seedlings, appropriate topdressing of potash fertilizer or nitrogenous fertilizer, and foliar fertilizer on the shoots, potassium dihydrogen phosphate, sprayed once every 7 to 10 days, and sprayed 3 to 4 times, to prevent and cure diseases. The effect of premature aging prolongs the functional period of the leaves at the late growth stage.
2, science watering. Because ginger prefers a moist environment, the field must have sufficient moisture. In order to ensure the smooth emergence of ginger, on the basis of soaking the bottom water before sowing, generally do not perform watering before emergence, and must wait until 70% of ginger seedlings are unearthed and then watered. The specific conditions should be flexible according to weather, soil texture and soil moisture status. grasp. If the first water is poured late, the ginger seedlings will suffer drought and the buds will easily dry out. Because the plastic film has a good role in the preservation of seedlings, seedlings should not be too hard watering, and the small water poured into the film is appropriate. Watering in the morning is good for morning and evening. Do not water at noon. At the same time, pay attention to timely drainage after the rain. Before and after the beginning of the autumn, the ginger needs more water to enter the vigorous growing season. In this period, the water is poured for 4 to 5 days to keep the soil moist. In order to ensure that the clay is less sticky after harvest, it is convenient for storage. The last water can be poured 3-4 days before harvest. After the application of branching fertilizer, according to the growth of ginger, the soil should be 2-3 times in time to ensure that the growth does not reveal the soil surface and promote the rapid growth of ginger.
