Problems solved by technology

Although the country has been advocating the development of modern irrigation agriculture for many years, the current water-saving irrigation technologies for farmland are mostly water-saving technologies such as pipe irrigation and sprinkler irrigation. The application of this technology requires a large one-time investment, high maintenance costs, and a high degree of mechanization. , poor operation and other defects. Among them, sprinkler irrigation is greatly affected by the climate, and it loses more in the air, and it only moistens the surface of the soil, while the deep layer is not moist enough.

Embodiment 1

[0043] The raw material components and weight percentages of the micro-irrigation tape are:

[0044] Polyethylene particles 55% (w / w); antioxidant 9% (w / w); EVA particles 17% (w / w); toner 3% (w / w), defoamer 7% (w / w); toughening agent 9% (w / w); put the above ingredients into the container according to the proportion, stir evenly, enter the mold cavity to melt and plasticize at 130-150°C, extrude through the mold, and cool. Pulled by the tractor, the product is rolled into the winder to form the product. The diameter of the drip irrigation belt is 30mm, the wall thickness is 0.15mm, and the aperture is 0.6mm.

Embodiment 2

[0046] The raw material components and weight percentages of the micro-irrigation tape are:

[0047] Polyethylene particles 65% (w / w); antioxidant 8% (w / w); EVA particles 12% (w / w); toner 2% (w / w), defoamer 6% (w / w); toughening agent 7% (w / w); put the above ingredients into the container according to the proportion, stir evenly, enter the mold cavity to melt and plasticize at 130-150°C, extrude through the mold, and cool. Pulled by the tractor, the product is rolled into the winder to form the product. The diameter of the drip irrigation belt is 45mm, the wall thickness is 0.3mm, and the hole diameter is 0.8mm.

Embodiment 3

[0049] Such as figure 1 As shown, in a certain greenhouse (60 meters × 7 meters), a micro-irrigation belt 9 is laid every 0.6 meters, and the water is directly supplied by the water pump 3. 32mm, the water enters the filter 6 through the water delivery pipe 2, enters the main pipe 7, and has a diameter of 6mm; then enters the branch pipe 8, and finally transports the water to the micro-irrigation belt 9 to irrigate the crops. The above specific implementation methods are also applicable to farmland irrigation.

[0050] The technical parameters of the micro-irrigation tape: folding diameter X: 30-70mm; wall thickness Y: 0.1-0.3 mm; micropore diameter Z distribution range: 0.5-0.8mm; drip hole spacing S: 20-40 cm; working pressure: ≤0.02 MPa; burst pressure: ≥0.7 MPa.

Abstract

The invention discloses a novel micro-irrigation belt and a preparation method and an application thereof. The entire novel micro-irrigation belt is a belt-shaped pipe body; the outer surface of the belt-shaped pipe body has a convex-concave structure; and the side wall of the belt-shaped pipe body is provided with a plurality of micro holes. The micro-irrigation belt comprises the following raw material components in percentage by weight: 75-90 percent of polyethylene particles, 5-10 percent of an antioxidant, 5-7 percent of EVA (Ethylene Vinylacetate) particles, 1-3 percent of a toner, 4-9 percent of an antifoaming agent and 2-6 percent of a toughening agent. In application to agricultural irrigation, the micro-irrigation belts are paved in a field at the intervals of 0.5-1 meter, are connected with a water pump through a filter, and are connected with the filter through a pipeline. The micro-irrigation belt disclosed by the invention has the advantages of reasonable formula, wide raw material source, simple production process, good anti-ageing effect and high anti-blocking performance. The surface of the micro-irrigation belt is uneven, micro holes of the micro-irrigation belt are distributed uniformly, and the micro-irrigation belt is elastic, so that high anti-ageing performance, high anti-bonding performance, uniform water dripping and high anti-blocking performance are realized, and the micro-irrigation belt is suitable for an irrigation system in which a modern cultivating way is adopted.

Description

technical field [0001] The invention relates to micro-irrigation technology, in particular to a novel micro-irrigation tape and its preparation method and application. Background technique [0002] At present, most of the irrigation areas in my country adopt relatively backward traditional surface irrigation technology. The phenomenon of flood irrigation is quite common, and the efficiency of irrigation water utilization is extremely low. The average irrigation water utilization coefficient is only 0.4, while developed countries can reach 0.7-0.8. The water use efficiency is only 1kg / m 3 , while developed countries are all at 2.0kg / m 3 above. Although the country has been advocating the development of modern irrigation agriculture for many years, the current water-saving irrigation technologies for farmland are mostly water-saving technologies such as pipe irrigation and sprinkler irrigation. The application of this technology requires a large one-time investment, high ma...
