Ginger has different growth characteristics and characteristics of sucking fertilizer in its different growth stages. In addition to applying the base fertilizer, it should also be topdressed in stages to meet the nutrient requirements of ginger growth. Under moderate fertility conditions, 25 to 30 kg of nitrogen, 8 to 10 kg of phosphorus, and 30 to 35 kg of potassium per acre are applied in three times of topdressing.
1. At the seedling stage, the plant growth is small, and the fertilizer is not much, but the seedling period is very long. In order to make the seedling grow robust, usually the seedling height is about 30 cm and there are 1 or 2 small branches, the first top dressing is carried out. It is called "small top dressing" or "strong seedling fertilizer". 15 to 20 kg of ammonium sulfate can be applied per acre.
2, before and after the fall, is the turning point of ginger growth, but also the turning point of absorption of nutrients. Therefore, before and after the fall, the ginger should be removed or the ginger shed should be removed for the second top dressing. This top dressing plays an important role in promoting root enlargement and obtaining high yield. This top dressing requires the combination of farmyard manure with quick-acting fertilizer and quick-acting fertilizer. It can apply 70-80 kg of cake fertilizer per mu, or 3000 kg of decomposed high-quality manure, plus 15-20 kg of compound fertilizer or ammonium sulfate. On the north side of the ginger seedling, a fertilization ditch is opened about 15 cm from the base of the plant, and the fertilizer is applied into the ditch to mix the soil and the fertilizer, and then the soil is sealed.
3. In the first ten days of September, when the ginger carp has 6-8 branches, it is also the period of rapid expansion of the rhizome. According to the general growth of the plant, the compound fertilizer or ammonium sulphate can be applied in an amount of 20-25 kg per acre; The ginger field with good soil fertility and strong plant growth can also be applied less or not as appropriate, so that the stems and leaves are long and the rhizome enlargement is affected.
