Problems solved by technology

Although the latter one can breed three crops per year, it needs to heat the water for two months, which consumes a lot of energy.

Embodiment Construction

[0006] Breeding equipment: a large pond and two small ponds (one of which is used for water exchange and preheating) constitute a group of breeding ponds, and the outside of the breeding ponds is covered with a greenhouse.

[0007] The depth of the small pond is the same as that of the large pond but the area is 1 / 3 of the large pond, and the bottom of the small pond is higher than the water surface of the large pond and is connected by pipelines.

[0008] Breeding procedure: Put 300,000 to 400,000 prawn larvae / (mu·meter water depth) in a small pond at the beginning of March every year, in which the water in the pond has been warmed up to 23±1°C, and the other small pond is used to store water for water change. The pool water was warmed to 23±1°C.

[0009] When the water temperature in the breeding pond can reach 22-23°C without heating, usually in mid-March, stop heating the breeding water.

[0010] At the beginning of April, the prawns in the small pond and the water body a...

Abstract

The invention provides a multi-crop greenhouse prawn cultivation method. Prawns are harvested after being cultivated for three months in a culture pond and a next crop pf prawns are continuously cultivated after harvest. A large tank and a small tank are in a group and the size of the small tank is one third of that of the large tank. The cultivation process comprises that the prawns are cultivated in three crops between March and September, every crop of the prawns are cultivated in the small pond in the first month and are cultivated in the large tank in the later two months, a later crop of prawns are cultivated in the small pond in the first mouth when the previous crop of prawns are cultivated at the beginning of the third month, the cultivation density in the small tank is from 30 to 40 million larvae every (mu. meter water depth), and water inside the tanks are warmed after half month in March. Compared with the prior art, consumed time and water consumption are reduced by two ninths, and the energy consumption is reduced by eleven twelfth.

Description

technical field [0001] The invention relates to a method for cultivating prawns in multiple crops in a greenhouse. Background technique [0002] With the continuous improvement of market demand, shrimp farming has also entered the stage of factoryization. Shrimp farming in greenhouses is a way of industrial farming. The cement ponds for cultivating prawns are covered with greenhouses, so that the prawn farming ponds are in a basically stable environment, so as to improve their growth environment and reduce the chance of disease. The greenhouse prawn farming technology currently used is the multi-crop method in one more pond, that is, multiple crops of prawns are cultivated in the same pond in a year, so that the output of prawns per unit area is increased, and the farming production efficiency is increased. The multi-crop culture method in one pond is usually to breed two crops between April and September every year, and each crop is three months. There are also three crop...
