Circulating adjustable crop water irrigating system and method

Abstract

The embodiment of the invention discloses a circulating adjustable crop water irrigating system and method. The system comprises a water-soil interlayer unit, a power supply unit, a data collecting and analyzing module and an atomization and drop-irrigation module, wherein the water-soil interlayer unit is used for carrying out layering in crop planting soil and forming a direct water culture space for a plant root in a crop root, and the atomization and drop-irrigation module is controlled to work according to results, of water content detection data of a soft soil layer and water level datain the water-soil interlayer unit, analyzed by the data collecting and analyzing module. According to the irrigating method, a crop planting region with transpiration gradient is firstly formed, an irrigating water channel is formed, water flow in the irrigating water channel is maintained by virtue of a water supply system so as to realize water culture internal circulation, the water level in the irrigating water channel is controlled in real time, and combined irrigation is carried out in a drop irrigation manner, and moisture in the soil in the crop planting region naturally infiltrates into the irrigating water channel so as to form drop irrigation external circulation, so that irrigation of crops is efficiently realized, and a transpiration effect of plants is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of greenhouse crop planting, and in particular to a cycle-adjustable crop water irrigation system and method. Background technique [0002] The existing automatic irrigation system for greenhouses generally irrigates evenly, but in fact, the soil moisture distribution in the greenhouse is uneven. The soil near the sides of the scaffold has more moisture infiltration outside the greenhouse and the flow of water droplets on the greenhouse film, so the soil outside the greenhouse The humidity is high, and the middle of the greenhouse is relatively dry. [0003] And because the transpiration of different crops is different, traditional sensors can only monitor the temperature and humidity changes in the overall crop growth space, and cannot realize different watering controls for different plants. In snowy weather, waterlogging is easy to occur in the greenhouse, and the moisture in th...

Problems solved by technology

[0005] Therefore, the embodiment of the present invention provides a cycle-adjustable water irrigation system and method for crops, which can effectively solve the problem that traditional sensors can only monitor the temperature and humidity changes in the overall crop growth space due to the different transpiration effects of different crops. , it is impossible to achieve different watering control for different plants, and at the same time, the hollow interior space of the greenhouse is relatively closed, so in rainy and snowy weather, it is easy to cause waterlogging in the greenhouse, and the moisture in the soil cannot be quickly drained manually. In the rainy weather, it is easy to have the problem of root rot
