Taking lotus root as an example, the traditional practice is generally: 20-30 kg of high-nitrogen-potassium compound fertilizer is applied at the beginning of vertical leaf stage (with 3-5 leaves). Fertilizer 15-25 kg. In some cultivation areas, based on the application of organic fertilizer, nitrogen and potassium fertilizers are topdressed once every 10-15 days after planting, and a total of topdressing is performed 7 times, and the amount of each fertilizer is 10%-15% of the total; Each application of basal fertilizer and top dressing is about 50%. Among them, the amount of fertilizer used to collect lotus seeds and picking lotus root flour was significantly higher than that of only picking fresh lotus root. In addition, we also do this for aquatic vegetables such as oysters and clams. This method of topdressing nitrogen and potassium fertilizers is consistent with the nutrition laws of aquatic vegetables and is conducive to high quality and high yield of crops.
