Problems solved by technology

In other words, an irrigation cycle of intermittent irrigation can be composed of three time periods: waterlogging stress period (AE), normal irrigation period (ED) and drought stress period (DA'), so each irrigation cycle will be repeated once Alternative drought and flood stress, which is obviously unfavorable to the growth of crops
[0007] In addition, since crops absorb water continuously every moment, it can be seen that the existing intermittent irrigation method is not an irrigation method that meets the characteristics of crops.

example 1

[0108] 1. Choose light calcium carbonate as the filler, and use the surface treatment agent AEO with a weight percentage of 8:100 to the filler to pretreat the filler.

[0109] 2. Blend and granulate the pretreated filler and PE resin at a weight ratio of 60:40.

[0110] 3. Put the prepared granules into the pipe production line, and make preformed pipes with the required caliber through extrusion, cooling, sizing, drawing and other processes.

[0111] 4. Lead the preformed tube into a continuous high-temperature extraction machine, and use the extract solution composed of water and sodium dodecylbenzenesulfonate with a weight percentage of 100:1 to carry out continuous extraction at a temperature of 85 ° C, and make a micro-water volume after cooling Continuous irrigation pipe.

[0112] It has been measured that the water yield of the micro-water continuous irrigation pipe is 170ml / m·h, which is a high-water-yield micro-water continuous irrigation pipe, and is suitable for m...

example 2

[0115] The only difference from the procedure described in Example 1 is that the pretreated filler and PE resin are blended and granulated at a weight ratio of 40:60.

[0116] It has been determined that the water yield of the micro-water continuous irrigation pipe produced by this method is 80ml / m·h, which is a low-water-volume continuous micro-water irrigation pipe, and is suitable for micro-water continuous irrigation of crops with low water demand.

example 3

[0118] Reduce the amount of surface treatment agent AEO in the above case 1 to 2% (that is, the weight percentage with filler is 2:100).

[0119] It is determined that the micro-water volume continuous irrigation pipe produced by the method has a small micropore diameter, and the distribution range of the pore diameter is reduced to 10-300nm. As the diameter of the water outlet channel becomes smaller, when the pressure is 2 meters, the water output per unit time of the micro-water continuous irrigation pipe drops to 20-30ml / m·h, and a higher water source pressure is required to increase the water output. Therefore, this micro-water continuous irrigation pipe is suitable for the situation that tap water is used as the water source and the high pressure of the water source is used for irrigation, such as family garden irrigation and the like.

Abstract

The invention provides a method for manufacturing a continuous micro water amount irrigation pipe, a continuous micro water amount irrigation pipe manufactured by the method, a method for irrigating by using the continuous micro water amount irrigation pipe, and application of the continuous micro water amount irrigation pipe to agricultural irrigation. The method for manufacturing the continuous micro water amount irrigation pipe comprises the following steps: preprocessing filling materials; mixing the preprocessed filling materials with high-pressure polyethylene resin by preset ratio of parts by weight to manufacture filling granule materials; manufacturing the filling granule materials into a preformed pipe; leading the preformed pipe into a high-temperature extraction machine to be continuously extracted to manufacture the continuous micro water amount irrigation pipe. The method can be used for manufacturing the continuous micro water amount irrigation pipe of which the pipe wall is provided with micro holes. After the continuous micro water amount irrigation pipe is filled with water, the water can leak out of the micro holes, the water yield is accurate and can be adjusted, and the continuous irrigation by the micro water amount through the way of continuous water supply for 24 hours is realized for crops in a full life circle way.

Description

technical field [0001] The invention relates to the field of irrigation, in particular to a continuous irrigation pipe with a small amount of water and a manufacturing method thereof, a method for using the continuous irrigation pipe with a small amount of water for irrigation, and an application of the continuous irrigation pipe with a small amount of water in agricultural irrigation. Background technique [0002] The history of irrigation technology is almost as long as the history of human agricultural civilization. In the course of thousands of years of development, there are four commonly used irrigation methods, namely: ground irrigation (including flood irrigation methods such as canal irrigation and border irrigation), drip irrigation, and sprinkler irrigation. and percolation. The common feature of these four irrigation methods is that they all belong to intermittent irrigation. The operation method is basically to stop for a period of time (several hours or several...
