Mixed culture method of rice, lotus roots and fishes and shrimps

Abstract

The invention discloses a mixed culture method of rice, lotus roots and fishes and shrimps. The method comprises the following steps of: (1) applying base fertilizer; (2) planting the lotus roots; (3)growing the rice; (3) releasing the shrimps; (4) releasing the fishes; (5) putting bait; and (6) performing topdressing. According to the mixed culture method of the rice, lotus roots and fishes andshrimps, a required growth environment of the lotus roots and fishes and shrimps is utilized fully, the soil can be loosened when the shrimps crawl, and since the fishes like digging mud for food, sothat formation of viscous and moderately loose soil and mud which are suitable for the growth of the lotus roots is facilitated when mixed cultivation is conducted; meanwhile, since air breathing is needed for the growth of the lotus roots, enough-content oxygen supplementation for the fishes and shrimps and the air breathing requirement can be achieved at the same time by means of transmission through holes in the lotus roots; farming of the fishes and shrimps and the growth of the lotus roots complement each other, and acidic fertilizer rich in organic matter is applied to the soil cooperatively, so that the lotus roots have stout and strong rhizomes, thick lotus root pulp, a thick and solid lotus root shape and high quality; in addition, floating-body rice is put in a pool of the lotusroots, so that the pool of the lotus roots is utilized fully.

Description

technical field [0001] The invention relates to the field of planting and breeding, in particular to a mixed breeding method of rice, lotus root and fish and shrimp. 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. [0003] The single planting method that adopts aspect the lotus root cultivation at present, only plant lotus root in the pond, ca...

Too loose soil is likely to cause short distance between lotus root nodes, thick skin and flesh, and poor quality

[0003] At present, a single planting method is adopted in the cultivation of lotus root, and only lotus root is planted in the pond, which leads to insufficient utilization of the pond and low economic benefits
