Abstract

The present invention discloses a method for cultivating river crabs in a lotus root pool. The method comprises the following steps of: applying a base fertilizer, planting lotus roots, releasing crabs, feeding baits and carrying out topdressing. According to the method disclosed by the prevent invention, a growth environment needed by the lotus roots and the river crabs is sufficiently utilized; when the river crabs creep, soil can be loosened, so that sticky and properly tight soil can be formed in a poly-culture process, and the growth of the lotus roots is adapted; meanwhile, the lotus roots need to breathe air to grow, and the air is transmitted through holes in the lotus roots, so that the enough oxygen amount can be supplemented to the river crabs and the requirements are met; and the culture of the river crabs and the growth of the lotus roots are complementary, and an acidic fertilizer with abundant organic matters is applied into the soil, so that roots and stalks of the lotus roots are strong, lotus root pulp is thick, the shapes of the lotus roots are thick and strong and the quality of the lotus roots is high.

Description

technical field [0001] The invention relates to the field of planting and breeding, in particular to a method for cultivating river crabs in lotus ponds. Background technique [0002] Lotus root, also known as lotus root, is the plump underground stem of lotus. The lotus root is slightly sweet and crisp. It can be eaten raw or cooked, and it is of high value 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. Contents of the invention [0003] Purpose of the invention: the purpose of the invention is to provide a method for cultivating river crabs ...
