Embodiment 1

[0019] Such as figure 1 Described: the rare fish rice paddy field micro-flow water ecological culture method described in the present embodiment, comprises the following steps:

[0020] ①Paddy field selection: Select a contiguous paddy field with excellent water source, convenient drainage and irrigation, and deep cultivation layer. Because the selected fish species are precious, the water source of the selected paddy field is groundwater, river water or reservoir tail water. The pH value of the water quality is required to be 7, dissolved oxygen >6mg / L, total hardness calculated as calcium carbonate is 89.25mg / L, water temperature is 15°C, organic oxygen consumption <30mg / L, ammonia <0.1mmol / L, sulfide is not allowed;

[0021] ②Paddy field reconstruction: according to the terrain scale of the paddy field, build a 2-meter-wide ridge 1 around the paddy field. The ridge 1 is 1.2m higher than the paddy field. The breeding and management of the rice field, the water inlet 5 and t...

Embodiment 2

[0028] Such as figure 1 Described: the rare fish rice paddy field micro-flow water ecological culture method described in the present embodiment, comprises the following steps:

[0029] ①Paddy field selection: Select contiguous paddy fields with excellent water sources, convenient drainage and irrigation, and deep cultivation layers. Because the selected fish species are precious, the water source of the selected paddy fields is groundwater, river water or reservoir tail water. The pH value of the water quality is required to be 7.8, and the dissolved oxygen >6mg / L, total hardness calculated as calcium carbonate is 123.8mg / l, water temperature is 20°C, organic oxygen consumption <30mg / L, ammonia <0.1mmol / L, sulfide is not allowed;

[0030] ②Paddy field reconstruction: according to the terrain scale of the paddy field, build a 2.5-meter-wide ridge 1 around the paddy field. The ridge 1 is more than 1.2m higher than the paddy field. For feeding and management of fish, water inle...

Embodiment 3

[0037] Such as figure 1 Described: the rare fish rice paddy field micro-flow water ecological culture method described in the present embodiment, comprises the following steps:

[0038] ①Paddy field selection: Select contiguous paddy fields with excellent water sources, convenient drainage and irrigation, and deep cultivation layers. Because the selected fish species are precious, the water source of the selected paddy fields is groundwater, river water or reservoir tail water. The pH value of the water quality is required to be 8.5, and the dissolved oxygen >6mg / L, total hardness calculated as calcium carbonate is 142.8mg / l, water temperature is 15-25°C, organic oxygen consumption <30mg / L, ammonia <0.1mmol / L, sulfide is not allowed;

[0039] ②Paddy field reconstruction: According to the terrain scale of the paddy field, build a 3-meter-wide ridge 1 around the paddy field. The ridge 1 is 1.8m higher than the paddy field. The feeding and management of the rice field, the water...

Abstract

The invention discloses a micro-flowing-water ecological breeding method for rare fishes in a rice field. The breeding method comprises the following steps of (1) selection of the rice field; (2) rice field transformation, wherein an enclosing ridge is built around the rice field, a water inlet and a water outlet are formed in the enclosing ridge of the two opposite corners of the rice field, then, fish ditches of cross-shaped structures are dug in the rice field, and finally, a feeding breeding ditch communicated with the fish ditches is dug in one side of the rice field; (3) rice planting, wherein manual transplanting of rice seedlings is conducted in rice planting areas in the rice field; (4) fry release, wherein 15 days after transplanting of the rice seedlings, fry are stocked in the feeding breeding ditch, and most of fry of sinocyclocheilus graham, schizothorax taliensis, neolissochilus benasi and spinibarbus sinensis bleeker are stocked; (5) feeding management, wherein after the planted rice seedlings turn green, artificial feed needs to be added into the feeding breeding ditch every day; (6) daily management. The allocation of mixedly-bred fry types is reasonable, planning for the rice field is proper, a scientific feeding mode is adopted, the growth speed of the fry is increased, and the yield of rice is also increased, so that the benefit of mixed fish breeding in the rice field is significantly increased.

Description

technical field [0001] The invention belongs to the technical field of comprehensive rice-fish farming, and in particular relates to a micro-flow ecological breeding method for rare fish in paddy fields. Background technique [0002] The golden-threaded barb belongs to the genus Golden-threaded barb of the subfamily Cyprinidae, and it is a national second-class protected animal. It is a rare fish. The market price of Yunnan's "Four Famous Fishes" is 600 yuan / kg. In 2018, it passed the national certification of the first new aquatic species in Yunnan; Soft-finned lip fish belongs to Cypriniformes Cyprinidae Cyprinidae subfamily Xinguang lip fish, commonly known as leopard fish and flower fish, is a rare fish unique to Yunnan and Southeast Asia. It has high ornamental value and practical value. The current market price is 500-600 Yuan / kg, breaking through the artificial propagation technology in recent years, the market prospect is broad; Chinese barb belongs to Cyprinidae Cyp...
