Embodiment Construction

[0022] A kind of Procambarus clarkii, fish, water celery polyculture rotation method, comprises the following steps:

[0023] (1) Fifteen days before stocking Procambarus clarkii and fish, aquatic plants were planted in the fish pond, and the aquatic plants accounted for about 50% of the water surface of the pond. Elodea and other aquatic plants were selected in this embodiment.

[0024] In the first ten days of March, 500 / kg Procambarus clarkii seedlings were stocked at 70 kg / 667㎡, in mid-March, 8 silver carp and bighead carp were stocked at 350 kg / 667㎡, and 10 carp / kg crucian carp were stocked at 35 kg / 667㎡;

[0025] (2) According to the total weight of Procambarus clarkii to be fed as the formula feed standard, the daily feeding amount accounts for 7% of the total weight of Procambarus clarkii, and the total bait is fed twice a day at around 9:00 in the morning 20%-30% of the total bait amount, 70%-80% of the total bait amount fed around 17:00 in the afternoon, and the prot...

Abstract

The invention discloses a mixed culturing and rotation method of procambrus clarkii, fishes and water cresses, comprising the following steps of: (1) stocking the young procambrus clarkii in the first ten-day period of March and stocking chubs, variegated carps and crucian carps in the middle ten days of March; (2) feeding 5-8% of feed to the procambrus clarkii in every day based on the total weight of the procambrus clarkii; (3) taking out all the aquatic products from the pond at the end of April and pumping the water in the pond; (4) removing the excessive sludge, keeping the sludge at the thickness about 0.3m, and flattening the bottom of the pond and digging a water discharge trench; (5) spreading seed stems of the water cresses with the length around 3cm into the pond and transplanting when the water cresses are more than 20 cm. In the method in the invention, the characteristics that the water cresses have strong fertilizer absorbing capability to reduce organic matters in the pond are used on one hand, and the characteristics that the aquatic organisms are rich after the water cresses are harvested are used on the other hand, and the residual leaves of the water cresses are the natural baits for the procambrus clarkii and fishes so as to reduce the feed amount, decrease the production cost and have obvious yield increasing effect and synergy.

Description

technical field [0001] The invention relates to aquatic products and vegetables, in particular to a polyculture rotation method for aquatic products and vegetables. Background technique [0002] With the improvement of people's living standards, the consumption of aquatic products has also increased, and the contradiction between aquatic products and planting has become more and more prominent. Therefore, how to realize the sufficient supply of aquatic products under the condition of limited cultivated land has become the goal pursued by people. [0003] In recent years, people have used polyculture technology to effectively increase the unit breeding output of water bodies, but in winter, when aquatic products are in a dormant state, water bodies are still not fully utilized. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a polyculture rotation method of Procambarus clarkii, fish, and water celery. In any seas...
