Problems solved by technology

In the case of such a high water utilization rate, if the humidity of drip irrigation has reached the level required by the plants, continuing to water will cause a waste of water
In view of the above technical problems, if it is detected manually, the workload will be very large

Abstract

The invention discloses a drip irrigation system of saline land and a control method thereof. The drip irrigation system comprises desalination equipment, drip irrigation equipment and a control cabinet. Clean water in a clean water pond of the desalination equipment is extracted by a water pump and filtered to be conveyed into a main pipe and then to all branch pipes and dripped out of drip emitters for irrigating plants. The control cabinet is connected with a first-stage infrared module in an infrared communication mode. The first-stage infrared module is electrically connected with a first-stage valve which is arranged at a water outlet end of the water pump. The first-stage infrared module is connected with multiple second-stage infrared modules in an infrared communication mode. All the infrared communication modules are in a one-to-one correspondence with all the branch pipes and electrically connected with second-stage valves of all the branch pipes. The second-stage infrared modules can shut down or open up the second-stage valves.All the branch pipes are provided with third-stage infrared emitters in a one-to-one correspondence with the drip emitters. The third-stage infrared emitters are electrically connected with humidity sensors of soil for the drip emitters. The drip irrigation system of saline land and the control method thereof fulfill the irrigation purpose without wasting water.

Description

technical field [0001] The invention relates to the technical field of saline-alkali soil irrigation, in particular to a control method of a saline-alkali soil drip irrigation system. Background technique [0002] Saline-alkali soil is a general term for saline soil and alkaline soil, and its soil salt content is too high (over 0.3%), which makes crops low-yield or unable to grow. Since most of the soluble salts in the saline-alkali soil are sodium salts, the soil is sticky, the soil colloid is dispersed and emulsified, the aeration is poor, it swells and becomes muddy when exposed to water, and shrinks hard when it loses water, which seriously affects the germination of crop seeds and the normal development of crops. In addition, soil sodium ions Too much alkaline reaction will directly damage plant tissue, and the root system of crops is also easy to rot, affecting the transformation of nutrients, so that phosphate fertilizers and trace elements cannot be dissolved and bec...
