Method for simultaneously producing rice grains and ctenopharyngodon idellus

Abstract

The invention belongs to the field of ecological aquaculture and relates to a method for simultaneously producing rice grains and ctenopharyngodon idellus. The method comprises the steps: (1) selecting a rice field; (2) constructing fish ditches and fish pits; (3) carrying out disinfecting treatment; (4) carrying out pre-fertilization; (5) carrying out rice seedling transplanting; (6) arranging culture trays and culture dishes: selecting the culture trays, of which bottoms have frames and are sealed with the frames, filling up the culture trays with a base fertilizer, placing the culture trays in the rice field in a manner that the culture trays are located above the fish ditches and are arranged above the fish ditches at intervals of 3 to 5 meters, arranging turntables on the ground aside the fish pits, erecting the turntables, arranging the culture dishes at the periphery of each turntable, sufficiently applying a base fertilizer into the culture dishes; (7) planting forage: planting zea Mexicana in the culture trays and the culture dishes; (8) carrying out fingerling stocking; (9) feeding the ctenopharyngodon idellus; (10) carrying out weeding and deinsectization on the rice field; and (11) carrying out rice harvesting. According to the method, on the premise of not affecting the growth of rice, the growing environment of the ctenopharyngodon idellus is optimized, and the yield of the ctenopharyngodon idellus is increased.

Description

technical field [0001] The invention belongs to the field of ecological aquaculture and relates to a method for simultaneously producing rice and grass carp. Background technique [0002] Grass carp is one of the unique "four major fish" in my country. It is a typical herbivorous fish. It is rich in nutrition, high in protein, and has the characteristics of fast growth, strong adaptability and high yield. It is the main food for people. protein. In 2009, the national grass carp aquaculture output was 4.08 million tons, accounting for more than 40% of the total output of the "four major fishes", and its industrial status is very important. [0003] The traditional method of feeding grass carp is to raise them in fish ponds. As we all know, in the process of aquaculture, a large amount of ammonia, nitrogen, phosphorus and other substances will be produced in the water body due to the excretion of aquatic organisms and the decomposition of residual bait. If it is removed in ti...

The disadvantages of artificial breeding products in this way are high fat, poor taste, and reduced umami taste

[0004] At present, there is a method of using rice fields to raise fish, but it is not perfect, and it cannot perfectly combine the habits of rice and grass carp. For example, grass carp is not suitable for growing in an environment with too much silt, and weeding or insecticide will affect fish. Growth. In addition, after grass carp eats terrestrial grass, its growth rate is much faster than that of edible aquatic plants. If grass carp is planted and then cut to feed fish, it will take time and effort, and land will be occupied
