A water-saving irrigation method for side seepage irrigation in shallow wells

Abstract

The invention discloses a shallow shaft side infiltrating irrigation water saving irrigation method. Compared with the prior art, the method is high in technical content, low in work amount, low in facility cost, and small in floor space of a main facility, and ground operation is not influenced. Equipment is not needed to move in a production process, and manpower and energy are saved. No pipeline exists underground, and ploughing and turning up soil are not influenced. A self-flowing method is used, and almost not power is needed in an irrigation process. Water is irrigated from the lower part of a plough layer, irrigated water does not infiltrate through a soil surface, so surface soil continuous permeability is maintained, and breath of roots of plants is not interrupted, and development of the plants is not inhibited. The method would not make nutrition be washed away. The surface of soil keeps a dried state all along, and the soil layer is loose, air and optothermal are sufficient, biochemical action is active, and large amount of nutrient contents and carbon dioxide are generated, so plant growth is flourishing. The method keeps the surface of the soil layer dry and loose, and stops underground water evaporation, so water saving effect is more obvious. The method is worthy of popularizing and using.

Description

technical field [0001] The invention relates to an agricultural irrigation implementation technology, in particular to a water-saving irrigation method for shallow well side seepage irrigation. Background technique [0002] In the vast inland areas, due to the drought and lack of rainfall, the development of planting cannot be separated from irrigation. Over the years, people have used unreasonable irrigation methods such as flood irrigation. On the one hand, water resources have been wasted, and on the other hand, groundwater levels have been continuously raised, causing secondary salinization of large areas of land. Later, people gradually introduced water-saving irrigation technologies such as sprinkler irrigation, drip irrigation, and micro-irrigation under mulch, which not only saved water resources, but also reduced the rise of groundwater levels. However, these irrigation technologies have a series of problems such as high facility cost, large space occupation, affec...

Problems solved by technology

However, these irrigation technologies have a series of problems such as high facility cost, large space occupation, affecting field operations, and increasing labor intensity of planting. Farmers are unwilling to accept them, and the process of popularization and utilization is slow.

In response to this situation, it is further recognized that improving water-saving irrigation technologies such as sprinkler irrigation, drip irrigation, and micro-irrigation under mulch that are currently widely used by people can only make progress in improving water saving rates and reducing equipment costs, but cannot eliminate the space they occupy. Large, affecting field operations, increasing labor, increasing energy consumption and other disadvantages

And these drawbacks are just the main obstacles for its difficult popularization and utilization.
