Description

Technical Field

[0001] The invention relates to the field of integrated irrigation of fertilizer and water in agriculture, forestry and garden pipe networks, and in particular to underground drip irrigation, and is a core component of underground pipe network irrigation. Background Art

[0002] The entire growth and development process of plants is closely related to fertilizer and water. As one of the elements of plant growth environment besides light, temperature, soil and air, fertilizer and water are related to the biological yield and quality of plants. Timely and good fertilizer and water supply can not only maintain appropriate soil moisture, but also meet its growth needs in different growth periods. In agricultural production, most agricultural land, especially mountainous areas, do not have agricultural irrigation facilities installed, and the water supply of crops mainly depends on natural precipitation. It often happens that crops cannot get effective water supply when they need water, and their growth is hindered. In severe cases, they wilt or even die, resulting in reduced production or crop failure. Improving the environmental conditions for plant growth is related to yield and quality, which has attracted people's great attention. In the production process, people have made many attempts to improve the plant growth environment and achieved good results. Irrigation facilities are born in agricultural production, and the improvement and update are accelerating. For example, in the north, drip irrigation belt technology has been widely used to solve irrigation problems; in tree and gardening, drip irrigation and sprinkler irrigation technologies are widely promoted to solve irrigation problems. The use of facility irrigation not only effectively solves the problem of plant fertilizer and water supply, but also greatly improves irrigation efficiency and saves production costs; at the same time, it promotes the scale operation of plant cultivation. With the continuous improvement of irrigation technology, irrigation methods have become diversified. Irrigation has evolved from relying on manpower to pipe network supply, from traditional ditch irrigation to precise point supply, and from qualitative irrigation to quantitative irrigation, showing a development trend of more, faster, better and cheaper. From the working principle of irrigation, the diverter, as the core component of the irrigation system, has a different water discharge principle from drip irrigation (or drip tape); drip irrigation and drip tape use the water pressure of the irrigation pipe network to transmit irrigation water to the destination. The drip head is one water outlet point, which is directly connected to the pipe network. The amount of water output is proportional to the diameter of the drip head and the water pressure. The water discharge effect is achieved by consuming the kinetic energy of the irrigation water. Due to the influence of one water outlet point, the water outlet diameter is small and easy to cause blockage; the diverter also uses the water pressure of the irrigation pipe network to transmit irrigation water to the destination, and can divert irrigation water into 2, 3, 4-n water outlet points. It makes full use of the kinetic energy of the irrigation water in the pipe network to achieve the water discharge effect. Because there are multiple water outlet points, the water outlet diameter is large and not easy to cause blockage. Especially when installing an underground irrigation pipe network system on fragmented cultivated land (the soil matrix is ​​broken and cannot hold gravity water), the water seepage device configured in the system can prevent irrigation water from directly wetting the soil below for a short time, prolong the time of wetting upward and around, and increase the contact area between the water supply point and the soil. When the soil is short of water, the fertilizer water will be quickly absorbed by the surrounding soil and quickly transport the water upward and around, and the irrigation water-saving effect is significant. From the perspective of soil types suitable for irrigation systems, ground irrigation systems are suitable for all soil types. Underground irrigation is suitable for loose sandy loam soil. In heavy soil, it is affected by the small wetting area of ​​the water supply point. It is suitable for point irrigation of plants with low planting density, and the effect is good; but it is not ideal for crops with high planting density.From the perspective of the effect of irrigation, the surface irrigation water needs to soak the soil to a certain depth before it can reach the main root distribution layer of the plant, and then be absorbed by the plant to relieve the drought; while the underground irrigation system has its water supply point located in the soil at a certain depth, the irrigation water can quickly penetrate upward and around, and the main root system of the plant is distributed around the water supply point, the irrigation effect is fast, and the fertilizer and water utilization rate is high. From the perspective of the impact on large-scale operations, the ground irrigation system has its facilities located on the ground, which affects mechanized operations. For example, when the soil is mechanized and plowed, it will damage the pipe network, causing the pipe network to be unable to function again; if drip irrigation belts are used for irrigation, changing them every year will increase the workload and cause waste; while the underground pipe network irrigation can well overcome these problems faced by the ground pipe network irrigation, but because the pipe burial depth is not deep enough, the use of heavy agricultural machinery will also cause damage to the pipe network, which is suitable for light agricultural machinery farming. From the perspective of the cost of using the irrigation pipe network system, the ground irrigation pipe network system has a short service life because its facilities are exposed all year round, and the pipe network is prone to aging and damage, but the system is fast to establish and the cost is low; and the establishment of an underground pipe network irrigation system requires more work such as digging pipe trenches and leveling the land, as well as adding some necessary facilities, compared with the ground network construction, and the one-time investment is larger, but the service life after completion is longer. In summary, ground irrigation and underground irrigation have their own advantages and disadvantages. Plants with low planting density in loose sandy loam and clay soil are suitable for installing underground pipe network irrigation systems; while other situations are suitable for installing ground pipe network systems. At the same time, the underground pipe network irrigation system can well integrate modern information technology, and can continuously upgrade the system and develop in the direction of automated and intelligent irrigation, thereby greatly improving irrigation efficiency and quality.
