Embodiment Construction

[0016] Such as Figure 1-2 As shown, a sediment collection device in a rice-fishing interaction system includes a pipe A 1 and a pipe B 4; the upper and lower ends of the pipe A 1 are open, and the upper end of the pipe A 1 is provided with a first handle 2 and a second handle. Two handles 3; the upper end of the B pipe 4 is open and the lower end is closed, and the upper end of the B pipe 4 is provided with a scale 5; the diameter of the B pipe 4 is smaller than the diameter of the A pipe 1.

[0017] Both the first handle 2 and the second handle 3 are semicircular rings, fixed on both sides of the A tube 1 .

[0018] The first handle 2 and the second handle 3 are nylon braided ropes.

[0019] The materials of the A pipe 1 and the B pipe 4 are both PVC pipes.

[0020] The A tube 1 has a diameter of 30 mm and a tube length of 100 cm; the B tube 4 has a diameter of 25 mm and a tube length of 115 cm.

[0021] The distance between the first handle 2 and the second handle 3 is 2...

Abstract

The invention relates to a sediment collection device in a rice-fish interaction system and belongs to the field of fishery ecological environment research of aquatic science. The sediment collection device comprises a pipe A and a pipe B. The upper and lower ends of the pipe A are open and a first pull handle and a second pull handle are arranged on the upper end of the pipe A. The upper end of the pipe B is open and the lower end of the pipe B is closed. The upper end of the pipe B is provided with scales. The diameter of the pipe B is less than that of the pipe A. The sediment collection device realizes accurate acquisition of sediments of paddy rice having effective planting depth of 12-15 cm, can be operated simply and fast and realizes accurate acquisition of sediments at fixed depth.

Description

technical field [0001] The invention relates to a sediment collection device in a rice-fish interaction system, which belongs to the research field of fishery ecological environment in the discipline of fishery. Background technique [0002] The rice-fish interaction system is a compound agricultural production method that combines rice planting and aquaculture. Ecologically speaking, it is a rice-fish symbiotic ecosystem with rice and fish as the dominant organisms formed after the introduction of fish populations into the rice field ecosystem. my country has a long history of rice-fishing interbreeding, but its development level is low. The main technical difficulty is that the absolute productivity of the system is not accurately quantified to determine the comprehensive stocking quantity and final yield of aquatic products. Therefore, carrying out basic research on material circulation, reasonable ratio, environmental benefits, and economic benefits in the rice-fish int...
