Description

A farmer-level practical standard micro-irrigation system

technical field

The utility model relates to the technical field of water-saving irrigation, in particular to an irrigation system suitable for planting vegetables or economic crops in open fields and sunlight plastic greenhouses, covering an area of 10 mu to 100 mu, using different water sources, and being convenient for selection, installation, maintenance and management. Farmer-level standard micro-irrigation (including micro-sprinkler and drip irrigation) systems.

Background technique

Micro-irrigation (including micro-sprinkler irrigation and drip irrigation) is one of the most advanced irrigation technologies today. Micro-sprinkler irrigation is different from sprinkler irrigation. For densely planted crops, it can be used for full-scale sprinkler irrigation, and for sparse plants, it can be used for partial irrigation; drip irrigation emitters (drippers) have a smaller flow rate, and generally only partial irrigation can be performed. Micro-irrigation has significant advantages such as saving water, increasing production, saving labor, saving time, saving land, and irrigating according to crop needs. It is the preferred irrigation technology for developing efficient and water-saving irrigation in countries around the world today. The micro-irrigation system is generally composed of four parts: water source project, head hub, water transmission and distribution pipe network and sprinkler. The micro-irrigation system can use rivers, lakes, reservoirs, ponds, ditches and well springs with water quality that meet the requirements as water sources; the head hub is generally Including water pumps, power machines, control valves, safety valves, water purification devices, fertilization devices, measurement and protection devices, etc.; the water transmission and distribution network includes trunks, branches, capillaries, water supply valves (bolts) and pipeline connectors, etc.; Different from the outflow form, it is divided into two categories: drippers and micro-sprinklers. They are generally placed on the surface, and some drippers can be buried underground for irrigation.

Because the micro-irrigation system requires specialized technical design, and requires a high level of investment and operation management. Most of the micro-irrigation systems in my country are built in farms, orchards or large-scale vegetable bases with a certain scale, and their construction, operation management and planting modes must be implemented according to unified planning and design. Small-scale (for example, less than 100 mu, hereinafter referred to as "farmer-level") planting mode of economic crops, as well as small-scale open fields, sunlight plastic greenhouses, etc., have not yet developed corresponding systems that are convenient for users to choose and install applications.
