High yield method of mixed culture of fish and lotus root in format pond

The technology of mixed culture of fish and lotus root in the format pond is to divide the hardened lotus root pond into small squares of 2 square meters to 4 square meters, and planting lotus root in the grid, the average yield of lotus root per mu is 5000 kg, the yield of fish is 400kg ~ 450kg, and the net benefit is more than 10,000 yuan per mu. This technology can make use of barren pits, barren beaches, river beaches and scattered corners to build mixed culture of pond fish and lotus root, which has the characteristics of small investment, low cost, quick effect and high benefit, and is suitable for the development of thousands of rural households. It can not only increase economic income, but also improve market supply and enrich the vegetable basket of urban and rural residents, so it has a very broad promotion prospect.

First, the technical principle divides the lotus root pond into several small squares, which greatly increases the area of the hard wall in the pond, while the whipping of lotus root is the result that the expansion begins to accumulate nutrition when it encounters the hard wall, and the area of the hard wall increases greatly, and the yield of lotus root increases naturally.
