Abstract

The invention discloses an automatic farmland irrigation and drainage system. The automatic farmland irrigation and drainage system is mainly composed of a main control system 1, a detection unit 2, adrip irrigation device 10, a spray irrigation device 11, an electric three-way valve 12, an irrigation water pipe 13, a water supply system 14 and a water seepage pipe 15. Soil moisture content, airhumidity, wind speed and other conditions can be detected in real time according to crop growth cycle characteristics, an irrigation mode can be automatically selected for crop irrigation; when waterlogging occurs in a farmland, drainage is carried out through underground water seepage measures, and the advantages of various irrigation modes are brought into full play; and meanwhile harm of soil salinization and heavy metal residues is effectively reduced. The automatic farmland irrigation and drainage system can be widely applied to modern agriculture and forestry automatic irrigation and pasture, urban landscaping and other irrigation systems.

Description

technical field [0001] The invention belongs to the field of farmland irrigation, and relates to a farmland automatic irrigation system, in particular to a farmland automatic irrigation and drainage system. Background technique [0002] Anti-drought and drainage of farmland are necessary measures to ensure stable and high yields of crops. Sprinkler irrigation can control the amount of water sprayed and the uniformity of irrigation water, avoiding surface runoff and deep seepage losses that are prone to occur during surface irrigation, thus improving water use efficiency and saving irrigation water . It has the advantages of increasing production, producing labor, saving land, suppressing diseases and insect pests, and facilitating foliar fertilization, but at the same time, there are also shortcomings such as sprinkler irrigation being greatly affected by wind and air humidity and not suitable for crop pollination; although drip irrigation overcomes the shortcomings of sprin...
