Embodiment 1

[0017] Embodiment 1: a kind of method of cultivating Macrobrachium rosenbergii in the lotus pond, comprises the following steps:

[0018] (1) Apply base fertilizer: lotus pond every 600m 2 Apply 2700kg of decomposed manure as the base fertilizer. After leveling the bottom of the pool, put it into the water at a ratio of 1:1 to the volume and mix it evenly with an iron rake. Keep the silt of 40cm in the cultivation layer, and wait for ten days for the mud to harden;

[0019] (2) Planting lotus root: every 600m 2 Plant 145kg of lotus root seeds, evenly implant in the soil, and inject water with a depth of 40cm in the pool;

[0020] (3) Shrimp stocking: 2 weeks before stocking shrimps, put quicklime into the water for disinfection, the dosage is 150kg / 600m 2 ; Shrimp seedlings were soaked in 1% peracetic acid solution for 20 minutes before putting them in. 2 27,000 macrobrachium rosenbergii seedlings were invested;

[0021] (4) Feeding: Feeding palatable pellet feed twice a d...

Embodiment 3

[0032] Embodiment 3: a kind of method of cultivating Macrobrachium rosenbergii in the lotus pond, comprises the following steps:

[0033] (1) Apply base fertilizer: lotus pond every 620m 2 Apply 2800kg of decomposed manure as the base fertilizer. After leveling the bottom of the pond, put it into the water at a ratio of 1:1 to the volume and mix it evenly with an iron rake. Keep the silt of 45cm in the cultivation layer, and wait for ten days for the mud to harden;

[0034] (2) Planting lotus root: every 620m 2 Plant 150kg of lotus root seeds, evenly implant in the soil, and inject water with a depth of 45cm in the pond;

[0035] (3) Shrimp stocking: 2 weeks before stocking shrimps, put quicklime into the water for disinfection, the dosage is 150kg / 600m 2 ; Shrimp seedlings were soaked in 1% peracetic acid solution for 20 minutes before putting them in. 2 28,000 macrobrachium rosenbergii seedlings were invested;

Abstract

The invention discloses a method for culturing Macrobrachium rosenbergii in a lotus root pond. The method comprises the steps of basal dressing, lotus root planting, Macrobrachium rosenbergii putting, bait feeding and topdressing. According to the method, the growing environment needed by lotus roots and the Macrobrachium rosenbergii is fully utilized, the lotus roots and the Macrobrachium rosenbergii both adapt to a weak acidic growing environment, and therefore the lotus roots and the Macrobrachium rosenbergii supplement each other in the mixed culture process; meanwhile, the Macrobrachium rosenbergii group can help form mud with appropriate tightness to adapt to growing of the lotus roots; meanwhile, the lotus roots need to breathe air to grow, the air is transmitted through holes in the lotus roots, and therefore the requirements are met while enough oxygen content is supplemented to the Macrobrachium rosenbergii group, acidic fertilizer rich in organic matter is applied in the mud, therefore, the rhizomes of the lotus roots are fat and fleshy, the lotus root flesh is thick and solid, the lotus root shape is thick, and the quality is high; the Macrobrachium rosenbergii is caught on the middle third of October, the shells are thin, the bodies are fat, the flesh quality is fresh and tender, the taste is delicious, the nutrition is rich, and 100 g of the Macrobrachium rosenbergii flesh contains 35.4 g of protein and 0.6 g of fat.

Description

technical field [0001] The invention relates to the field of planting and breeding, in particular to a method for cultivating Macrobrachium rosenbergii 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 cultivatin...
