Description

Continuous low pressure irrigation system is collected to big-arch shelter rainwater

Technical Field

The utility model relates to an agricultural water-saving irrigation technical field, concretely relates to continuous low pressure irrigation system is collected to big-arch shelter rainwater.

Background

At the southeast edge of the cloud noble plateau in Guangxi, the northwest relief is high, the southeast relief is low, the rainfall distribution is very uneven, the south and the north are more, the east and the middle are second, the west rainfall distribution is least in the west, and the drought disaster is caused by unique geographic environment and climate factors, so that the yield of the grains is reduced, and the income of farmers is reduced. Water resources are precious, especially in water-deficient areas with insufficient rainwater, and in these areas, agricultural irrigation needs to be carried out strictly in accordance with the principle of water-saving irrigation so as to avoid damaging the environment. The original wild irrigation is not suitable for modern requirements, and the refined management becomes a development direction. In recent years, water-saving irrigation is taken as the key point of Guangxi agriculture in Guangxi, and efficient water-saving irrigation is promoted.

The current water-saving irrigation mode is the technology of canal seepage-proofing lining, sprinkling irrigation, drip irrigation and the like. The water-saving effect of different irrigation technologies is different, and the channel seepage-proofing technology mainly utilizes various technical measures and engineering measures to prevent water in a channel from leaking and losing, reduce the waste of water resources and increase the utilization rate of the water. Thereby achieving the purpose of saving water. The utilization coefficient of the traditional earth canal water storage is generally 0.4-0.5 difference and is only about 0.3, namely, most of water leaks and is evaporated and lost. The spray irrigation is an irrigation mode that pressurized water is sprayed into the air through mechanical components such as pipelines, spray heads and the like, and is dispersed into water drops which are uniformly dropped on the ground, and the spray irrigation can be combined with pesticide spraying and liquid fertilizer spraying, so that the spray irrigation method is an ideal irrigation method. It is widely used as an advanced mechanized, semi-mechanized irrigation mode. However, compared with ground irrigation, the investment of sprinkling irrigation is high, and the sprinkling irrigation is greatly influenced by wind and air humidity. When the wind speed is 5.5-7.9m/s, namely more than four-grade wind, water drops can be blown away, the irrigation uniformity is greatly reduced, and the drift loss is increased. When the air humidity is too low, evaporation loss increases. Clogging of the emitter is the most important problem in current drip tube applications, and in severe cases, the whole system cannot work normally or even is scrapped. The cause of the blockage may be a physical factor, or a chemical factor. Such as silt, organic matter or microorganisms in the water, and chemical precipitates.
