1, to apply base fertilizer. According to ginger, the nutrient requirement is mainly in the middle and late period. The production of basal fertilizer with organic fertilizer as the main ingredient is the key technology for high yield of ginger. Before sowing, 500-600 kilograms of chicken manure is to be sown in combination with high-quality compost per acre. When the next seedlings per acre to ditch (points) 75-100 kg cake fertilizer, nitrogen, phosphorus, potassium fertilizer 50 kg or 15 kg of urea, superphosphate 30 kg, 20 kg of potassium sulfate. For soils lacking trace elements, 1-2 kg of zinc sulfate and 0.5-1 kg of 0.05-0.1% borax are added per mus of the base fertilizer.
2, to give light "strong seedling fertilizer." The seedling stage has a small amount of plant growth and requires little fertilizer, but the seedlings have a long growth period. In order to promote the growth of the seedlings, the seedlings usually grow at a height of about 30 cm and grow 1-2 branches for the first time. The topdressing fertilizer is dominated by nitrogen fertilizer. Apply ammonium sulfate or diammonium phosphate 20 kg per acre. If the sowing date is too early and the seedling period is longer, the above fertilizer can be used in combination with pouring water 2-3 times.
3, to re-apply "fork fertilizer." Before and after the beginning of autumn, Ginger entered the growth transition period, the plant growth accelerated, and began to accumulate large amounts of nutrients. Therefore, in order to increase the demand for fertilizer and water, in order to ensure high yield of ginger, combined with cultivating and weeding before and after the beginning of autumn, we will re-apply once a manure-based fertilizer to promote the healthy growth of the plant, and prepare enough nutrients for root enlargement. Generally, 60-80 kilograms of crushed cakes are used per mu, 250-300 kilograms of chicken manure is decomposed, 50-80 kilograms of compound fertilizer or 10 kilograms of urea, 25 kilograms of diammonium phosphate, and 25 kilograms of potassium sulfate are applied to the side of the plants. A small ditch (a hole) is opened at the centimeter, and the fertilizer is sprinkled into it, and then the soil is covered and poured.
4, to cleverly apply "inflated fertilizer." When the white dew to the equinox plant grows 6-8 branches, the ginger enters the rhizome rapidly expanding. This time, according to the growth of the plant, it is necessary to apply a strong ginger fertilizer. Generally 25-30 kg of compound fertilizer per acre or ammonium sulfate, potassium sulfate, 2-3 kg each. For adequate soil fertility and vigorous plant growth, little or no nitrogen fertilizer should be applied to prevent stems and leaves from becoming long and affecting rhizome enlargement.
5. Apply foliar fertilizer. For soils lacking boron, zinc, and other trace elements, seedling stage, split period, and rhizome enlargement period, a top dressing of 1-2 kg of zinc sulfate and 0.05-1.
