Soft-shelled turtles, frogs and fishes ecological rice planting and breeding method

Abstract

The invention discloses a new soft-shelled turtles, frogs and fishes ecological rice planting and breeding method, which comprises the following steps: (1) ditching a farmland, and forming an upper water outlet and a lower water outlet in the ditch; wherein the ridge is 0.8 m high, and an adhesive layer is laid in the ridge; (2) after the farmland is built, irrigating water in the farmland by 0.6m deep, putting crucian carps, carps, soft-shelled turtles and frogs into the farmland; (3) when rice seedlings are transplanted in the next year, after water in the farmland is drained to the depth of 2 cm, performing ploughing for rice seedling transplanting, putting fishes into ditches, and applying rape seed cakes; (4) after transplanting rice seedlings for half a month, irrigating water in the farmland to a depth of 5cm, and putting small grass carps into the farmland; (5) gradually increasing the water level in the growth process of the seedlings so as to ensure that the fishes in the farmland swim sufficiently; (6) when the unhulled rice is about to ripen, draining water, opening an upper water outlet to dry the field, putting the fish into ditches, and collecting the unhulled rice;and (7) after the rice is harvested, irrigating water in the farmland for 0.6 m deep, and putting grass carps, spotted silver carps and silver carps into the farmland to breed to the next year. A three-dimensional integrated insect prevention and weeding system is formed, and 900 jin of ecological rice is produced 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 frogfish. Background technique [0002] In today’s era, people’s requirements for food safety and quality are getting higher and higher. Traditional rice planting relies on chemical fertilizers and chemical pesticides to increase yields. The problem of pesticide residues and heavy metals is serious, and food safety issues may exist, which does not meet people’s requirements for food. Claim. [0003] The Chinese invention patent application with application number CN201810417609.7 discloses an ecological breeding method of rice-turtle-fish co-cultivation mode, including the following steps: (1) rice field transformation; (2) selection of aquatic polyculture varieties and rice seeds :Aquatic product species selection: aquatic product selection of soft-shelled turtle, snail, crucian carp, g...

Problems solved by technology

But this invention does not illustrate that by the method of this invention, the yield per mu of the obtained rice is not much, although the overall economic benefit has been improved, but the yield per mu of rice has not been improved, and there are still relatively large defects.
