The method comprises the steps of paving a stainless steel wire mesh, a gravel layer, a quartz sand layer, a dirt bed, a fertilizer layer and a mud layer at the bottom of a culture pond; planting lotus root seeds in the mud layer; pumping out water in the culture pond, and pumping clean water into the culture pond; putting young black shrimps into the culture pond; putting shrimp feed with 1mm-grain size into the culture pond three times a day during the first to the second month of black shrimp putting; putting the shrimp feed with 3mm-grain size into the culture pond four times a day during the third month to the fifth month of black shrimp putting; putting the shrimp feed with 3mm-grain size into the culture pond five times a day during the sixth month of black shrimp putting. According to the method provided by the invention, the black shrimp farming and the lotus root farming are combined, the use ratio of the culture pond is improved, and compared with separate farming, the usage amounts of a fertilizer and the feed are greatly saved, and by utilizing the method disclosed by the invention, the cultured lotus roots are fertile, white and tender, and fragrant and sweet in mouthfeel, moreover, the black shrimps are rich in nutrition and delicious in taste.

Description

technical field [0001] The invention relates to a method for cultivating freshwater shrimp in lotus ponds. Background technique [0002] Lotus root, also known as lotus root, is slightly sweet and brittle. It can be eaten raw or cooked, and its value is quite high. It can be used as a nourishing medicine. Lotus root likes relatively stable still water, avoids running water with great fluctuations and strong waves, and requires sufficient sunshine. The lotus root has higher requirements on the soil. The soil quality should be clay loam rich in organic matter, and weakly acidic. Excessive acidity is not conducive to the growth of lotus root. Too loose soil is likely to cause short distance between lotus root nodes, rough skin and flesh, and poor quality. Freshwater prawn is one of the freshwater prawns that people often eat. It is not only delicious in quality, but also rich in nutrition. At present, the culture in my country is monoculture, which not only has low economic v...
