As preferably, described water tank is positioned at described honeycomb duct below, and honeycomb duct and water tank corresponding position are provided with discharge orifice, and the cross section in described honeycomb duct and annular water guide road is all recessed arc.This is provided with and is beneficial to flowing of water body, the better effects if that makes to collect rainwater.
As preferably, the water inlet end of described salt discharging pipe and sprinkler pipe is respectively equipped with a magnetic valve, in described stone sand bed and plantation layer, be respectively equipped with a pH value detector, in described plantation layer, be provided with a moisture detector, described magnetic valve, pH value detector and moisture detector are all connected with an electric control gear.This setting can be carried out pH value detection to stone sand bed and plantation layer, also can carry out Humidity Detection to plantation layer, and then opening and closing by electric control gear controlled quentity controlled variable magnetic valve, reach the object of automatic control, without artificial interference, more time saving and energy saving, and control accuracy is high, effective, be more conducive to the growth of plant.
In sum, the utlity model has following advantage: annular water storage tank and water tank can be collected rainwater, have saved water resource, and the rainwater of collecting is rationally utilized; Salt discharging pipe water yield is large, and sprinkler pipe watering evenly, is conducive to the absorption of plant; Setting ring is avoided salt discharging pipe deformation; Watertight composition can avoid saline and alkaline in salt-soda soil around to infiltrate in improvement planting soil and affect planting site with water; Honeycomb duct exceeds salt-soda soil, edge, can avoid in the time of the rainy day saline and alkaline in salt-soda soil, edge to flow into plantation layer with water, also can avoid the water on surface, salt-soda soil to flow in water tank, the water quality that impact is irrigated.
