Which Type of Pond Liner is Best

The two types of geomembrane for breeding have their own advantages. The two main functions of the two kinds of geomembrane are anti-seepage. If only from the perspective of anti-leakage, their effect is the same. They are often required to have more functions when people use them. Also to the function of anti-seepage, other functions determine their use places. Let me explain to you what are the differences between the selection of anti-seepage geomembrane for aquaculture and fish ponds. How to choose geomembrane when it is applied in anti-seepage of the lotus pond and anti-seepage of the fish pond?

Geomembrane For Fish Pond Liner

Most people choose to use composite geomembrane for the anti-seepage membrane of the lotus pond liner. The two sides are non-woven fabrics and the middle is the white flexible geomembrane. The non-woven fabrics on both sides protect the middle flexible geomembrane. The key to preventing water leakage in the lotus pond in the middle of the geomembrane, the non-woven geotextile on both sides is to prevent humans and animals from destroying the flexible membrane in the middle and also prevent the lotus root from damaging the flexible membrane during the growth process. That is to say, the composite geomembrane can prevent the lotus root from penetrating and continuing to grow downward, so the lotus root is protected against Most people who will choose composite geomembrane.

Geomembrane For Fish Pond Liner

Fish pond anti-seepage people use Earth Shield geomembrane, also called fish pond anti-seepage membrane. Its structure is a single-layer high-density polyethylene geomembrane. There is no two-sided non-woven fabric. Why should we choose this one? Because non-woven geotextile is made of 100% virgin materials. The toxic substances that are not completely volatilized in the non-woven fabric can cause serious damage to the fish. Also, the smooth surface of the Earth Shield geomembrane can prevent the fish from escaping in the rainy season, especially like lobster, Crabs, soft-shelled turtles, loach, rice eels, and other fish that are good at escape.

Nowadays, fish pond breeding often encounters conditions such as long-term drought and low rainfall, lowering the groundwater level, and large water permeability of the fish pond soil, which will cause the fish pond to leak. Nowadays, most farmers have laid anti-seepage geomembrane on the bottom of fish ponds. Let’s analyze its necessity. The application of the anti-seepage earth shield geomembrane for fish pond breeding has solved the problem of anti-seepage in fish pond breeding very well. We remind the majority of fish pond breeding professionals that it is necessary to lay anti-seepage geomembrane for fish pond breeding:

After fishing in the winter, a reasonable plan is to first drain the pool water, dig out debris and silt, and dry it for 1 winter to 20 days, and spread a layer of 15-20 cm thick clay on the bottom and slope of the pool, and then use machinery rolled or compacted. Then lay a layer of 0.5 mm thick impermeable membrane as an impermeable protective layer, measure the relevant dimensions according to the shape of the fish pond, and then cut and splice the impermeable membrane according to the actual situation. The overlap width of the seam between the membrane and the membrane is usually not less than 15 cm. After the impermeable membrane is laid, try to reduce walking and moving things on the membrane surface. Anything that can damage the impermeable membrane should not be placed on the membrane or carried on the membrane. , To avoid accidental damage to the film. Then sow some grass seeds on the slope protection and install turf slope protection to prevent rain erosion.

Another role is also very important! For farmers. It’s cheap and convenient. Although it is selling this, it is important. Because farmers are very hard, it is not easy to do some breeding, and they will face various risks. As a necessity, it is recommended to use an impermeable membrane to make a pond. Because you take cement and make prefabricated things, will the materials be cheated? What is the quality, and how to correct it if you miss it? If there is a problem with the initial investment, what should I do later? Using this anti-seepage membrane to make a pond is effective and convenient. If you don’t want to do aquaculture, you can change other things, but you can make a cement pond. What should you do? Damn it? Move away?

I borrowed an algorithm from others about lotus root ponds: the development of shallow water lotus root planting over the past few years has resulted in considerable technological maturity and benefits, but the threshold for intervention is too high. The cost of building one mu of cement ponds is between 20,000 and 25,000 yuan, which is unbearable for ordinary farmers and entrepreneurs. Also, the country’s land protection policy generally does not allow construction and construction that destroy the cultivated layer on the cultivated land. Although the construction of cement pools is for agricultural production, due to the different understanding and implementation of policies, many constructions have been blocked, even fined or demolished. There is also the lease of land for planting lotus roots. After the lease term expires, if the lessor requests re-cultivation, the high re-cultivation fees, and construction waste will also be difficult to bear. Also, an impermeable membrane with a little thickness will have a long service life.
