Planting method for zinc-supplementing lotus roots

Abstract

The invention mainly relates to the technical field of aquaculture, and discloses a planting method for zinc-supplementing lotus roots. The method comprises a leaf standing period, a lotus rooting period and a harvesting period. The method is simple, and is convenient to operate; the yield of lotus roots reaches 3462 kg / mu; the zinc content reaches 3.47 mg / 100g; and the yield and the quality of the lotus roots are improved. Manganese sulfate is applied to a lotus root field during the leaf standing period, so that the growth of the root systems of the lotus roots is promoted, the absorption capacity of nutrients is improved, the growth of the lotus leaves and the accumulation of organic components are accelerated, and the content of organic zinc in the lotus roots is increased; bacillus natto powder is applied to the lotus root field twice during the lotus rooting period, so that the content of microorganisms in the lotus root field is increased, the absorption and conversion of the nutrient components by the lotus roots are promoted, the accumulation of starch and the organic zinc in the lotus roots is increased, the sweetness and crispness of the lotus roots are increased, and the fertilizer utilization rate is improved; and water content is reduced before harvesting, and an acetic acid solution is sprayed, so that red-brown rusty spots of the lotus roots are reduced, the absorption of the zinc element in soil by the lotus root field can be promoted, and the sweetness and crispness of the lotus root can be increased.
