Embodiment 1

[0028] The paddy field polyculture method of a kind of crayfish and Procambarus clarkii that the present invention proposes comprises the following steps:

[0029] A. Select a rice field with a length of 667 meters and a width of 15 meters, rich in water sources, no pollution in water quality, convenient irrigation and drainage, far away from surrounding farmlands, and free from the influence of fertilization and spraying of highly toxic pesticides as a polyculture rice field. Water outlet, water outlet, trim the field surface of the polyculture rice field, make the field surface of the polyculture rice field incline 4° from the water inlet to the water outlet, and set a 55-mesh mesh at the water inlet to filter the water; Excavate a ring-shaped ditch at 2.2m from the field ridge, and connect the ring-shaped ditch with the water inlet and outlet. The ring-shaped ditch is 1.7m deep, 0.55m wide at the bottom, and the angle between the two walls and the bottom is 65°; Excavate a ...

Embodiment 2

[0037] The paddy field polyculture method of a kind of crayfish and Procambarus clarkii that the present invention proposes comprises the following steps:

[0038] A. Select a rice field with a length of 667 meters and a width of 20 meters, rich in water sources, no pollution in water quality, convenient irrigation and drainage, far away from surrounding farmland, and free from the influence of fertilization and spraying of highly toxic pesticides as a polyculture rice field. Water outlet, water outlet, trim the field surface of the polyculture rice field, make the field surface of the polyculture rice field tilt 6° from the water inlet to the water outlet, and set a 65-mesh mesh at the water inlet to filter the water; Excavate a circular ditch at 1.8m from the field ridge, and connect the circular ditch with the water inlet and outlet. The circular ditch is 1.3m deep, 0.65m wide at the bottom, and the angle between the two walls and the bottom is 55°; Excavate a field ditch c...

Embodiment 3

[0046] The paddy field polyculture method of a kind of crayfish and Procambarus clarkii that the present invention proposes comprises the following steps:

[0047] A. Select a rice field with a length of 667 meters and a width of 18 meters, rich in water sources, no pollution in water quality, convenient irrigation and drainage, far away from surrounding farmland, and free from the influence of fertilization and spraying of highly toxic pesticides as a polyculture rice field. Water outlet, water outlet, trim the field surface of the polyculture rice field, make the field surface of the polyculture rice field tilt 5° from the water inlet to the water outlet, and set a 58-mesh mesh at the water inlet to filter the water; Excavate an annular ditch at 2.1m from the field ridge, and connect the annular ditch with the water inlet and outlet. The annular ditch is 1.5m deep, 0.63m wide at the bottom, and the angle between the two walls and the bottom is 58°; Excavate a field ditch con...

Abstract

The invention discloses a tor-brevifilis and procambarus-clarkii rice field mixed aquaculture method. The tor-brevifilis and procambarus-clarkii rice field mixed aquaculture method includes the steps of arranging a rice field, digging annular furrows and field furrows, building field ridges, and arranging protective devices; in February, planting water plants in a layered mode, and putting snails; carrying out disinfection and fertilizing after the mixed aquaculture rice field is cleared, and breeding young procambarus clarkiis at the time one week after fertilizing, wherein the breeding density ranges from 15,000 per mu to 20,000 per mu, and the breeding time is early May; in late-May, breeding tor brevifilises, wherein the density ranges from 1,300 per mu to 1,700 per mu; respectively feeding the tor brevifilises and the procambarus clarkiis, wherein the feeding time of the procambarus clarkiis is sixteen o'clock to eighteen o'clock, the everyday feeding amount is 2% to 3% of the weight of all the procambarus clarkiis, and the everyday feeding amount of the tor brevifilises is 4% to 7% of the weight of all the tor brevifilises; managing the water quality. The tor-brevifilis and procambarus-clarkii rice field mixed aquaculture method is easy to operate and control, the attack rate of the tor brevifilises and the attack rate of the procambarus clarkiis are reduced, the survival rate of the tor brevifilises and the survival rate of the procambarus clarkiis are increased, growing is rapid, and the economic benefits of farmers are high.

Description

technical field [0001] The invention relates to the field of culture technology, in particular to a method for polyculture of clamfish and Procambarus clarkii in rice fields. Background technique [0002] Osteophytes belong to Osteostichthyes, Cyprinidae, Cyprinidae, Subfamily Cyprinidae, Osteophytes, and Osteophytes subgenus. They are widely distributed in the Lancang River, Yuan River, Yangtze River, Pearl River and other water systems in my country. They are only seen in Vietnam abroad. of the Red River system. The growth rate of the petaled fish is average. The body length of 1 winter age fish is 19-19.5 cm; the body length of 2 winter age fish is 27.6 cm; the body length of 3 winter age fish is 33.8-34.6 cm; 0.5-1 kg, up to 8 kg, is a large and medium-sized freshwater economic fish in the production area. [0003] Different types of fish in different waters have different feeding methods and feeding habits, and even the same fish have different feeding methods and feed...
