Problems solved by technology

However, the structure and pipeline layout of the pressureless irrigation device are relatively complicated, the construction is inconvenient, the cost is high, and it is difficult to popularize on a large scale.
In addition, in the pressureless irrigation device, part of the irrigation water is lost in the form of continuous evaporation, so the utilization rate of irrigation water will be significantly reduced. water

Abstract

A pressureless irrigation apparatus, which contacts the soil (12) so as to irrigate the plants growing therein. The pressureless irrigation apparatus comprises: a water passing layer (21) laid inside the soil (12), the water passing layer being connected to a water pipe (23) so as to connect to the irrigation water; several through-holes (211) being provided on the top of the water passing layer (21); a water storage column (22) buried under the soil (12), the water storage column being in contact with the irrigation water through the through-holes (211), the material of the water storage column (22) being a water-absorbing material; and a control system (24) and a water supply valve (25) being electrically connected to the control system, the water supply valve (25) being provided between the water passing layer (21) and the water pipe (23), and the control system (24) controlling the opening and closing of the water supply valve (25) by means of monitoring the moisture of the soil (12), so as to control whether the irrigation water flows into the water passing layer (21). The pressureless irrigation apparatus improves irrigation uniformity, increases the utilization efficiency of the irrigation water, and reduces the cost of the apparatus.

Description

technical field [0001] The invention belongs to the technical field of irrigation, and in particular relates to a pressureless irrigation device. Background technique [0002] At present, the more mature methods for soil irrigation are generally divided into negative pressure irrigation and non-pressure irrigation. Negative pressure irrigation means that the elevation of the irrigation water source is lower than the elevation of the emitter, and the water supply head is negative during operation; while non-pressure irrigation is an irrigation method in which the elevation of the irrigation water source is equal to the elevation of the emitter. Although negative pressure irrigation is the most efficient irrigation method so far because it utilizes the water potential energy difference and capillary action of soil, plants, and the atmosphere to irrigate, it also has many shortcomings. It is very difficult to implement negative pressure irrigation. There are very strict requir...
