Embodiment Construction
[0028] The specific embodiment of the present invention is further described below:
[0029] A kind of ecological cultivation method of freshwater shrimp and water celery of the present invention is completed according to the following steps:
[0030]Take 12-15kg shrimp fry as an example:
[0031] 1) Pond conditions: Each pond uses an ordinary earthen pond of 3 to 5 mu, the slope ratio is 1:3 to 1:4, the dissolved oxygen is above 5mg / L, and the pH is 7.0 to 8.5. The vinyl double-layer dense mesh is tightly sealed to prevent the escape of shrimp seedlings and the invasion of harmful organisms. Around the pond, a ring ditch and a central ditch with a width and depth of 0.8 to 2 meters are excavated. The excavated soil is used for Reinforce the pond, the pond is 1.5 meters high, compacted and tamped firmly, no seepage and no leakage, the silt at the bottom of the pond does not exceed 10cm, the bottom is a slope structure towards the drainage, each pond is equipped with a water p...
