TECHNICAL FIELD
[0001] The utility model relates to a paddy field structure, in particular to a paddy field structure provided with fish pits. BACKGROUND
[0002] In some areas in the south, it is a habit to breed fish in paddy fields, and the traditional breeding mode is to put fry into the paddy field after rice seedlings are planted for a period of time, and fish are caught before or after the harvest of rice. Such planting mode has several problems: first, because fish are bred in the paddy field, chemical pesticides cannot be used to prevent and control pests and diseases, which will result in a low yield of rice. Second, the water level in the paddy field is relatively shallow, and the water temperature is high in summer, which will lead to a decrease in dissolved oxygen, an acceleration of fish metabolism, and an increase in oxygen consumption, thereby affecting the growth of fish and even causing death. Third, fish are caught before the harvest of rice, mainly for water release and field drying, so fish catching operation needs to be carried out before field drying, and because each paddy field is relatively flat, fish may exist in every area, so people need to search every area multiple times to avoid missing fish, which results in a large amount of time and labor being invested in catching fish; in some places, field drying operation is not needed when rice is harvested, which means that water always exists in the paddy field, and fish are caught after the harvest of rice, which is easier because there is no influence of rice, but it is more troublesome when rice is harvested because water always exists in the paddy field, so a fully automatic harvester cannot be used for operation, and only a semi-mechanical harvesting method can be used, which affects the harvesting efficiency of rice. SUMMARY
[0003] The utility model aims at providing a paddy field structure provided with fish pits. By providing fish pits in the paddy field, pesticide spraying and field drying operation can be carried out in the paddy field, and a habitat for fish can be provided in summer to prevent fish from dying, and fish catching operation is also facilitated, and the yield of rice can be improved.
