Abstract

The invention relates to a corn field water-saving irrigation system. The corn field water-saving irrigation system comprises a water tower, a water pump, an output main pipeline, conveying branch pipes, spray pipes and sprayers. The water pump is connected with the multiple conveying branch pipes, and each conveying branch pipe is provided with a branch valve which is independently controlled. The conveying branch pipes are fixed along the ground through hoops and positioning piles; protection boxes are arranged on the outer sides of the conveying branch pipes, wireless transmitters and soil moisture sensors are arranged in the protection boxes, and detection ends of the soil moisture sensors are inserted into the ground. A plurality of relay transceivers are arranged on the corn field; soil humidity data sensed by the soil moisture sensors are sent to the nearby relay transceivers through the wireless transmitters; and the multiple relay transceivers transmit the data in a relay mode, finally send the data to a data integrated controller and transmit the data to a control background through the data integrated controller, and the control background adjusts opening, closing and opening degrees of the branch valves of the conveying branch pipes and the power of the water pump according to a preset program so as to achieve the purpose of water-saving irrigation.

Description

technical field [0001] The invention relates to farmland irrigation facilities, in particular to a cornfield water-saving irrigation system and irrigation method. Background technique [0002] In the north of our country, the rainfall is relatively small, which is not suitable for rice cultivation. Corn has better drought resistance and is the main crop grown by farmers in the north. Corn can be used for food processing and feed processing, and is an important food crop. Although corn has good drought resistance, it also needs to be irrigated during the important part of corn growth. A corn plant consumes about 2kg of water per day during the flowering period, 3-4 cubic meters per mu per day, and 250-350 cubic meters of water during the entire growth period. Different breeding corns have different water needs. The period from 10 days before tassering to 10 days after tassering is the most water-requiring and most sensitive period in the life of corn, which is called the ...
