An experimental device for aquatic plants

Abstract

The invention relates to an experimental device for aquatic plants. The experimental device is composed of a raw water bucket, a water suction pump, a plant rack, water storage buckets, plant buckets and filtrate tanks. The water storage buckets are placed in the uppermost layer of the plant rack, the plant buckets are placed in the middle layer, and the filtrate tanks are placed in the bottom layer. Water in the raw water bucket is required to be pumped into the water storage buckets at the scale mark position with the pump so as to control flow rate. Under the condition of the controllable flow rate, the influence of the water flow rate on growth of the aquatic plants is researched. The experimental device is low in cost and convenient to operate, convenience is brought to laboratory users, the growth of the aquatic plants at different flow rates is researched conveniently, and our laboratory environment can be beautified.

Description

technical field [0001] The present invention relates to the experimental field of aquatic plants. In particular, it refers to an experimental device for aquatic plants. The advantages of the device are: the device is easy to operate, it is convenient to uniformly control the water inlet, water outlet, and its flow rate, and the device has the advantages of low cost, clean and hygienic, strong ornamental value, environmental protection and no pollution. Background technique [0002] The eutrophication of lakes is the most important water pollution problem facing the world today. With the rapid development of urbanization and industry, as well as the extensive use of chemical fertilizers and pesticides in agriculture, the process of eutrophication in lakes is accelerating, which has seriously affected water bodies. The poor water quality and environment lead to the decline of the lake's self-regulating function and the imbalance of the water ecosystem. Therefore, the eutroph...

Problems solved by technology

However, this method is difficult to study the growth of submerged water plants at different flow rates due to the uncontrollable flow rate.

[0004] The Chinese patent discloses an experimental device, an experimental system and an experimental method for aquatic plants (the patent number is: CN103371098A). More than two rotating mechanisms must be arranged in the described experimental cylinder, and the rotating mechanisms include: two groups The motor is connected to the fan blades through a coupling, and the motor in each bucket must be fixed by a bracket. The experimental device is complicated to set up and inconvenient to operate.
