A kind of turtle frog fish ecological paddy planting method

Abstract

The invention discloses a new method for planting and raising soft-shelled turtle frog fish ecological rice, which comprises the following steps: (1) Digging a ditch in the farmland, on which an upper water outlet and a lower water outlet are arranged; the field ridge is 0.8m high, and a rubber layer is laid in the field ridge; 2) After the farmland is built, the water in the farmland is closed to a depth of 0.6m, and crucian carp, carp, soft-shelled turtle and frogs are put in; Put it into the ditch and apply rapeseed; (4) half a month after transplanting the seedlings, close the water in the farmland to a depth of 5cm, and put small grass carp in the farmland; (5) gradually increase the water level during the growth of the seedlings to ensure that (6) Water is released when the rice is about to mature, and the upper water outlet is opened to dry the field, and the fish go down the ditch to harvest the rice; (7) After the rice is harvested, the water in the farmland is closed to a depth of 0.6m, and large Grass carp, silver carp and silver carp are cultured until next year. The invention forms a three-dimensional integrated pest control and weeding system, which can mass-produce 900 catties of ecological rice per mu.

Description

technical field [0001] The invention relates to the field of comprehensive agricultural planting and breeding, and specifically relates to a new method for ecological rice planting and breeding of soft-shelled turtles and frog fish. Background technique [0002] In today's era, people have higher and higher requirements for food safety and quality, while traditional rice planting relies on chemical fertilizers and chemical pesticides to increase production. The problem of pesticide residues and heavy metals is serious, and there may be food safety problems, which do not meet people's expectations for food. Require. [0003] The Chinese invention patent application with the application number CN201810417609.7 discloses a rice-turtle-fish co-cropping ecological breeding method, including the following steps: (1) paddy field transformation; (2) selection of aquatic polyculture species and rice species : Aquatic product selection: select soft-shelled turtle, snail, crucian carp...
