1. Micro-irrigation system planning and layout, data collection and sorting
Including terrain data, soil data, meteorological data, water source data, crop planting data and environmental data (road, electricity, etc.).
, The layout of the first hub location
Combined with the water source project, the principles are convenient management and low investment.
, Selection of Irrigators
Irrigators should meet:) The flow rate meets the design requirements) Reliable operation and not easy to clog) Neat performance specifications and small manufacturing errors) Simple structure and low price.
2. Layout of the pipeline system
The pipelines of the micro-irrigation system are generally divided into three levels: trunk pipe, branch pipe and capillary pipe. When laying out, the trunk, branch and capillary pipes are required to be as perpendicular to each other as possible to ensure that the length of the pipe is and minimal head loss.
Under normal circumstances, the water outlet capillary pipe in the protected area is generally required to be parallel to the planting direction, and the branch pipe is perpendicular to the planting direction. Capillary pipes, drip irrigation tapes, and micro-spray tapes all have laying length limits that need to be considered.
3. Characteristics of the small tube outflow water-saving irrigation system for fruit trees
Energy saving, less clogging problems, and simple water quality purification. The diameter of the flow channel of the small tube emitter is larger than the diameter of the flow channel or orifice of the drip irrigation emitter. Much more, and the use of large flow outflow solves the problem of drip irrigation system emitters being easily clogged. Therefore, it is generally sufficient to install a mesh filter at the head of the system (the filter media of the drip irrigation system filter requires a mesh). If you use well water with good water quality for irrigation or pool irrigation with good water quality, you don't need to install a filter. At the same time, due to the large mesh size of the filter and the small water head loss, it not only reduces energy consumption, but also prolongs the flushing cycle
Fertilization is convenient. When fertilizing fruit trees, the fertilizer liquid can be injected into the pipeline and enters the soil in the root zone of the crops along with the irrigation water. The fertilizer can also be spread evenly in the seepage ditch to dissolve and enter the soil with the water. Especially when applying organic fertilizers, various organic fertilizers can be mixed into the soil under the seepage ditch and matured under suitable water, heat and air conditions to fully exert the fertilizer effect and solve the problem of drip irrigation not being able to apply organic fertilizers.
Water-saving small tube outflow irrigation is a local irrigation technology that only moistens part of the soil in the active layer of crop roots on both sides of the seepage ditch. The water utilization rate is high, and water is transported and distributed through a pipe network, so there is no leakage loss. . According to tests in Beijing's Haidian District, it can save more than % of water compared to surface irrigation.
Strong adaptability and can be applied to various terrains, soils, various fruit trees, etc.
Simple operation and convenient management.
