Shallow-water lotus root planting method

Abstract

The invention discloses a shallow-water lotus root planting method. The method comprises the following steps of field selection, wherein a planting field is selected; lotus seed selection; field preparation and fertilizer application, wherein base fertilizer is applied before field preparation, after the base fertilizer is applied, deep plowing is carried out to turn the base fertilizer into soil, then leveling and thorough furrowing are carried out, and shallow water is introduced for retting; planting and close planting; staged topdressing, wherein tiller fertilizer is applied, application time is 30-40 d after lotus root planting, urea is applied by the ratio of 150-225 kg / hm<2>, thoroughly-decomposed manure is applied by the ratio of 22.5 t / hm<2>, lotus root yielding fertilizer is applied, and according to application time, when vertical leaves grow in the field full, ridgepole leaves come out of some plants, lotus roots begin to be yielded underground; urea is applied by the ratio of 300 kg / hm<2>, and calcium superphosphate is applied by the ratio of 300-375 kg / hm<2>; water level management, wherein during the earlier stage of growth, the water level is 5-10 cm, during the middle stage of growth, water is irrigated until the water depth is 15-25 cm, and during the late development stage, the water level is gradually lowered to 10-15 cm. The yield of shallow-water lotus roots can be effectively increased, and the quality of the shallow-water lotus roots can be effectively improved.
