Embodiment 1

[0034] A field protection land in a farm in Fengxian, Shanghai was selected, and cauliflower was cultivated in a plastic greenhouse. Before the cauliflower was planted, the ridge itself had divided the field into rectangular small ridges. Use tap water as irrigation water source. Lay common commercially available PVC main pipes and branch pipes (such as figure 1 and figure 2 shown in 3), branch pipes have been perforated according to the distance of about 30cm of cauliflower in the field, and connected with water seepage objects (such as figure 1 and figure 2 Shown in 4) sealed connection. Cover all the topsoil after paving, so that the seepage system is 20cm below the topsoil.

[0035] The water seepage object adopted is a two-stage pottery rod with a length of 3.5 cm, an upper diameter of 2 cm, and a lower diameter of 1.5 cm. One end of the larger diameter of the pottery rod contacts the soil, and the smaller diameter end is inserted into the water pipe. The pottery r...

Embodiment 2

[0041] A villa garden in a community in Thames Town, Songjiang, Shanghai, with an area of ​​about 400 square meters. Arrange PVC water pipes according to the planting layout of plant landscaping, set water seepage objects near the plants, generally at a distance of 30cm on one side, do not set them in the gaps of some plants, and set them densely around the big trees. All buried in the soil layer 30-40cm. The seepage object adopts 500g / m filter with reverse filtration effect 2 polyethylene geotextile. The geotextile is first clamped with a plastic sleeve that is compatible with the hole on the water pipe. The inner wall of the sleeve is provided with a protrusion, which can pinch the geotextile strip to limit its water output, and then insert it into the water pipe together.

[0042] The water source uses tap water, and the water source can be opened according to the weather and rainwater conditions during use. Generally, the water demand of plants can be guaranteed for abou...

Abstract

The invention relates to a method for filtration irrigation. The anti-blockage automatic filtration irrigation method of the invention is that water is transported to the soil of the plant root by the water seepage matter which touches the water source. By using the anti-blockage automatic filtration irrigation method, obtaining materials is easy, processing and installation are simple, and investment is small; compared with the prior art, the blockage phenomenon does not happen, and the difficult problem which can not be solved all the time in the technical field is solved. In the method forfiltration irrigation, water transportation to the soil of the plant root by the water seepage matter leads the water yield to be even and stable as well as be controlled easily, the water can be saved more, thus being in favor of growth and development of plants.

Description

technical field [0001] The invention relates to a kind of plant irrigation, that is, a method of infiltration irrigation. Background technique [0002] Irrigation is generally divided into furrow irrigation, border irrigation, sprinkler irrigation, drip irrigation, infiltration irrigation, watering and so on. [0003] (1) The furrow irrigation method is to open furrows and irrigate between rows between ridges. [0004] (2) The border irrigation method is to introduce irrigation water into the furrow, so that the water flow gradually penetrates into the soil. [0005] (3) Sprinkler irrigation and drip irrigation are new irrigation methods developed in recent years. Sprinkler irrigation is to send the pressurized water formed by the pressure of the water pump or the natural drop to the field through the pressure pipe, and then spray it into the air through the nozzle to form fine water droplets, which are evenly sprinkled on the farmland to achieve the purpose of irrigation....
