What about "fish farming in rice fields", which is on fire all over the country?

The larger the pond area, the higher the requirements for aquaculture technology, not to mention small rice fields. ? Fish farming in rice fields? It is a complicated and tedious process, and many farmers are unwilling to participate or quit. If they want to raise fish, there are many rivers, ponds and other water bodies in rural areas, and the scale of raising fish in paddy fields is much larger, which is more convenient for investment and development, and the technical and practical difficulties are much smaller.

Although? Fish farming in rice fields? Can increase fish yield, increase rice yield, improve soil fertility and improve soil structure in paddy fields. However, the requirements of aquaculture technology are high, and it is also greatly disturbed by the external environment. So in the past few years, it has been thriving and bustling. Fish farming in rice fields? In recent years, it has gradually died out and disappeared in some places.

There is no way to solve the water problem. In fact, this idea of raising fish in rice fields is very beautiful at first, but in practice, it does encounter many problems. The first problem to be solved is water source. The water system in the south is indeed relatively developed, but this does not mean that farmers can allocate water resources at will. In the south, the water source of many rice fields is directly extracted from ditches or surrounding ponds, and these water sources can only be used when rice grows.

If you want to raise fish in rice fields, the requirements for water quality and water quantity in rice fields are bound to be high. But most of the water sources in the surrounding ponds are quite turbid, and the fish will die of lack of oxygen. So if you really want to raise fish in paddy fields, you must change the water regularly, especially frequently, and at the same time, you must master the depth of the water. This kind of operation is very difficult, which is not only particularly hard for farmers, but also has no way to control it accurately. If you raise fish in rice fields, another big problem you need to face is pests. Planting rice on a large scale is really easy to attract pests. Although the bait in rice can eat a small amount of pests, it is not enough. If pesticides are used, the impact on children is very great, but if pesticides are not used, rice must be tested.
