Multifunctional water-flooded culture device and operation method

Abstract

The invention relates to a multifunctional water-flooded culture device and an operation method thereof, which are used for simulating the water-flooded environment of aquatic plants. The device comprises an outer barrel, an inner barrel, a supporting unit, a liquid level marking unit and a water inlet and drainage unit, wherein the inner barrel is of a hollow structure with an top opening and thelower part of the inner barrel is arranged in an inner cavity of the outer barrel, the top of the outer barrel and the outer wall of the inner barrel are well sealed, sand and soil are arranged in the inner cavity of the inner barrel, a lower plate is detachably arranged in the inner cavity of the inner barrel, the top of the lower plate is fixedly connected with a straight rod, a floating ball is slidably arranged on the straight rod, the straight rod, the lower plate and the floating ball form the liquid level marking unit, and a scale mark is arranged on the outer wall of the inner barrel;a through hole is formed in the outer wall of the lower part of the inner barrel, a supporting unit for supporting the plants is arranged on the inner side of the inner barrel, the water inlet and drainage unit is arranged between the outer barrel and the inner barrel, the water directly enters the inner barrel under the action of the water inlet and drainage unit, and the water in the inner barrel is discharged through the outer barrel. The device can conveniently achieve the flooding simulation of the aquatic plants.

Description

technical field [0001] The invention relates to the technical field of aquatic plant cultivation, in particular to a multifunctional water-flooding cultivation device and an operation method. Background technique [0002] Wetland is an important part of ecosystem, and flooding is an important environmental factor of wetland ecosystem. Flooding has an important impact on the growth and stress resistance of wetland plants. At the same time, the depth, time, frequency and intensity of flooding all have an important impact on the biodiversity and ecosystem functions of wetlands. However, due to the lack of relevant devices and the cumbersome operation of artificially simulating flooding, research on the impact of flooding on wetland plant growth has been hindered and limited. Therefore, there is a need for a multifunctional water-flooding culture device, which can carry out water-flooding treatment to aquatic plants according to experimental requirements.
