Embodiment Construction

[0018] Get above-mentioned plastic capillary, burial depth 40cm (40cm apart from ground), and pad film under the plastic capillary, film width is 30cm, the plastic capillary of the present invention is with the method well known to those of ordinary skill in the art and the other method of seepage irrigation. The matching parts can be connected to complete the seepage irrigation project.

[0019] After testing, the optimal technical parameters of the seepage irrigation project provided by the present invention are:

[0020] 1. The dry and branch pipes are in the shape of "Feng", the diameter of the branch pipe is 63mm, the spacing is 90m, the inner diameter of the infiltration capillary is 8mm, the spacing is 1.5m, and the buried depth is 40cm.

[0021] 2. The capillary specific flow rate of infiltration irrigation is 2-10l / m·h.

[0022] 3. The operating pressure difference of the capillary orifice for infiltration irrigation is ≤20%, and the flow rate difference is ≤10%.

Abstract

The present invention relates to a water-saving infiltrating irrigation method which can be extensively used in gardening and farmland, and is characteriized by that its capillary tube is made into the form of opened jet-flow plastic tube and the plastic film is laid under it.

Description

technical field [0001] The invention relates to the field of water-saving irrigation, in particular to a method for water-saving and yield-increasing farmland seepage irrigation. Background technique [0002] Infiltration irrigation is an irrigation method that uses an underground pipe system to introduce irrigation water into the field and moisten the root soil through the pipe wall holes. Experiments have proved that infiltration irrigation has the advantages of water saving, energy saving, soil structure maintenance and field management, but there are also problems such as easy clogging of seepage holes, uneven irrigation and high cost, so it is not easy to promote in actual production and application. Due to these technical difficulties, Europe, America and Japan have focused their water-saving research on commercial crops cultivated in facilities in recent years, and focused on sprinkler irrigation, micro-irrigation, and drip irrigation. At present, the rubber and plas...
