How to fertilize lotus root planting? Please give guidance on planting lotus root can refer to the following methods for fertilization: The growth and development of lotus root can be divided into three stages: germination stage, vigorous stage and lotus node stage. The germination stage starts from plant germination to leaf emergence. After leaf establishment, lotus root grows new roots, mainly depending on the nutrients stored by lotus root; during the flourishing period, from leaf establishment to lotus formation, the nutrient demand is large, which is the key period for topdressing; during the lotus formation period, from lotus formation to harvest, lotus root and lotus seed develop synchronously, nutrient absorption decreases, and most nutrients in stems and leaves are transferred to lotus root and lotus seed. Therefore, a total of three fertilizer applications. Before planting lotus roots, the base fertilizer will be turned into the field, and 2000~3000 kg of decomposed high-quality farm manure and 40~50 kg of general compound fertilizer will be applied per mu. There are two topdressing. The first time is leaf setting fertilizer, when 3~5 leaves appear in the field, apply 25~ 30kg nitrogen and phosphorus compound fertilizer per mu; the second time is full of leaves, apply 30~ 35kg nitrogen and potassium compound fertilizer per mu. In addition, shallow water lotus field and deep water lotus field fertilization is not the same, shallow water field can be applied compound fertilizer, but also can be applied simple chemical fertilizer. Drain water before application, fertilize in shallow water, and restore water layer two days after application.
