Description

A water storage and stable water pressure irrigation system

technical field

The utility model relates to the technical field of agricultural water-saving irrigation, in particular to a water storage and stable water pressure irrigation system and an irrigation method.

Background technique

Water is the lifeblood of agricultural production. Most of the farmland in Guangxi is "reliant on the weather". Agricultural production has long faced a shortage of irrigation water. Drought is the most frequent and most serious natural disaster. It has a serious impact on agricultural production. At the same time, agriculture is a large user of water, and the utilization rate of water resources is low. Guangxi's topography and geological conditions are special, the soil is red soil, its water retention capacity is weak, and most crops are planted on dry slopes without irrigation. It seriously hindered the improvement of crop yield and quality. In recent years, Guangxi has taken water-saving irrigation as the key point of Guangxi's agriculture, and implemented high-efficiency water-saving irrigation. Due to topographical reasons, the water supply pressure is often insufficient. Whether it is sprinkler or drip irrigation, there are certain requirements for water pressure. At present, in rocky desertification areas, water is often supplied through the top of the mountain. In places close to the water, the head pressure is often insufficient, and neither sprinkler nor drip irrigation can be carried out.

At present, the commonly used water-saving technologies mainly include different irrigation technologies such as channel anti-seepage, sprinkler irrigation and other technologies, and their water-saving effects are very different. The channel anti-seepage technology mainly uses various technical measures and engineering measures to prevent water in the channel. Leakage loss occurs, reducing the waste of water resources and increasing the utilization rate of water. to save water. The utilization coefficient of traditional earth canal water storage is generally 0.4-0.5, and the difference is only about 0.3, that is to say, most of the water is lost by leakage and evaporation. Sprinkler irrigation is an irrigation method in which water under pressure is sprayed into the air through mechanical components such as pipes and sprinklers, and dispersed into water droplets that fall evenly to the ground. Sprinkler irrigation can also be combined with spraying pesticides and liquid fertilizers, which is an ideal irrigation method. As an advanced mechanized and semi-mechanized irrigation method, it has been widely used. However, compared with surface irrigation, the investment of sprinkler irrigation is higher, and sprinkler irrigation is greatly affected by wind and air humidity. When the wind speed is above Grade 4 wind, the water droplets can be blown away, the irrigation uniformity is greatly reduced, and the drift loss will also increase. When the air humidity is too low, the evaporation loss increases, and there are certain requirements for the head pressure.

The beneficial effects of the present utility model are:

1. The utility model belongs to full pipeline water delivery and local micro-irrigation, which reduces the leakage and loss of water to a minimum, and at the same time, because it can supply the required water in the root zone of crops in a timely manner, there is no problem of loss of peripheral water. , and greatly improve the utilization rate of water.

2. The utility model can be combined with fertilization during irrigation, that is, the chemical fertilizer is dissolved and then injected into the irrigation system. Because the chemical fertilizer and the irrigation water are combined together, the fertilizer nutrients are directly and evenly applied to the root layer of the crops, which truly realizes the synchronization of fertilizer and water, and greatly improves the efficiency of fertilization. The effective utilization rate of fertilizer is improved, and at the same time, due to the small-scale local control, micro-end cap, and less leakage of fertilizer and water, it can save the amount of fertilizer application and reduce pollution.

3. In view of the technical characteristics of micro-irrigation, the water supply method is a continuous, quantitative and slow process per unit time, and due to the function of the water pressure stabilization tank, even in rainy days, the water level of the collection tank exceeds the daily water level. , the water pressure of the irrigation water is constant, the water pressure of the irrigation water will not fluctuate with the water level, but will be stable at the same level for a long time, the water supply and water consumption are balanced. The soil moisture consumed by transpiration can be replenished by micro-irrigation in time.
