A Tidal Mangrove Seedling Irrigation System

Abstract

The invention discloses a tidal mangrove seedling raising irrigation system, which comprises a seedling bed, a water inlet pump, a timing switch, a water inlet pipe, a timing valve, a drainage pipe, aliquid level sensor, a circulating pool and a salinity measuring device; the seedling bed has an accommodating space with an upward opening; the water inlet pipe is connected with a water inlet of the water inlet pump, and a water outlet of the water inlet pump is connected with the seedling bed; the seedling bed is connected with the water inlet of the timing valve, and the water outlet of the timing valve is connected with the drainage pipe; the water inlet pump is electrically connected with the timing switch and the liquid level sensor, the timing valve is electrically connected with theliquid level sensor. The tidal irrigation system starts flooding irrigation automatically at regular intervals and drains automatically after carrying out flooding irrigation for a fixed time. A salinity probe of a salinity sensor can be maintained continuously in the middle of the circulating pool so that the salinity of the water can be measured stably. The irrigation system is used for seedling raising irrigation of mangrove plants.

Description

technical field [0001] The invention relates to an irrigation system for agriculture and forestry, in particular to a tidal irrigation system for raising seedlings of mangroves. Background technique [0002] Agriculture and forestry irrigation methods include drip irrigation, sprinkler irrigation, and flood irrigation. Mangroves grow in the upper part of the tropical and subtropical low-energy coastal intertidal zone and are flooded by periodic tides. Therefore, flood irrigation is usually used in the process of artificial seedling cultivation of mangrove saplings. Its seedling survival rate. The existing flood irrigation technology requires manual participation in the drainage work of flood irrigation, and the operator has long labor hours and high work intensity. In addition, because mangrove plants have lived in seawater for a long time, they have adapted to the salinity of seawater. Some mangrove plants even need a certain concentration of salt to grow normally. Therefo...

AI Technical Summary

Problems solved by technology

Existing salinity meters mainly measure salinity through the conductivity of water, but temperature has an impact on the conductivity of water, while the temperature of the water surface in contact with the atmosphere and the area of ​​the pool near the wall of the pool varies greatly, and the temperature in the middle of the pool more stable
