Sandstone laminated filter manufacturers talk about the application of underground drip irrigation skills

Underground drip irrigation carried out faster, but relatively small area, is limited to cotton irrigation.
 
Underground drip irrigation (SDI) skills and their characteristics
 
SDI is a method of irrigation that absorbs water by applying a water or a mixture of water and fertilizer slowly into the soil in the root zone of the crop after it has been burnt on the ground capillary tube and dispersing the water to the root layer by capillary action or gravity .
 
Compared with other irrigation methods, SDI has the obvious advantages of significant water saving effect, high fertilizer utilization rate, optimization of agricultural product quality and increase of output value. With SDI skills to small flow, low head operations, saving operating costs and energy, system life is relatively long. There is a lack of mainly for the drip blocking questions, in addition, the depth of underground drip capillary tube must be buried in depth, the surface soil is usually more dry or inadequate water supply, so will affect the seed germination and emergence, irrigation uniformity is not easy to control.
 
Underground drip irrigation (SDI) engineering planning should pay attention to the questions
