Method for rebuilding field facilities for integrated rice and fish cultivation

The invention discloses a method for rebuilding field facilities for integrated rice and fish cultivation. The method mainly comprises the modification of ridges through thin film and light brick andthe change of a water inlet device and a drainage device so that the water level in rice fields can be kept at 30 cm above, water inlet and drainage in the rice fields remain unobstructed, the rice fields possess certain flood control ability, and aquatic animals grown in the rice fields can be prevented from escaping. The rice fieldsmodified by the method can greatly improve the living space of aquatic animals, and the yield of aquatic products per acre can reach more than 80kg, and the economic benefits are obviously improved. 本发明公开了种用于稻渔综合种养的田间设施改造方法，主要包括利用薄膜和轻质砖对田埂的改造以及对进水装置和排水装置的改变使得稻田内的水位能够保持在30cm以上，且进水和排水保持通畅还能够具备定防洪能力，避免稻田内养殖的水生动物逃逸的目的。采用本发明的方法改造的稻田能够大大提高水生动物的活动空间，且所养殖的水生产品亩产量能够达到80kg以上，经济效益明显提高。
