Embodiment 1

[0024] A kind of method of co-production of shrimp and rice, specifically comprises the following steps:

[0025] (1) Paddy field preparation: In January, the paddy field was divided into 50 mu as a unit, and an "L" shaped field edge shrimp ditch was dug along the outer edge of the field ridge. The depth of the ditch was 1.2 meters, the width of the ditch was 4 meters, and the slope ratio was 1:1.5. It is 0.6 meters above the field surface, and the top is 2 meters wide. The escape net is set up on the ridge; freeze-dry, air-dry and disinfect the shrimp ditch and rice field. Plant a bunch of aquatic plants alternately at intervals of 4 meters, 2 Elodea and 3 Hydrilla verticillium as a bunch of aquatic plants, distributed in a star shape.

[0026] (2) Shrimp feeding: From March to mid-April, after the aquatic plants take root and germinate, gradually add water to submerge the end of the aquatic plants by 15 cm, and then put high-quality shrimp seedlings in the shrimp ditch and r...

Embodiment 2

[0039] A kind of method of co-production of shrimp and rice, specifically comprises the following steps:

[0040] (1) Paddy field preparation: In February, the paddy field was divided into 50 mu as a single unit, and a "one" type of field edge shrimp ditch was excavated along the outer edge of the field ridge. The ditch was 1 meter deep, 4 meters wide, and the slope ratio was 1:1.5. It is 0.7 meters above the surface of the field, and the top is 2 meters wide. Escape nets are set up on the ridge; freeze-dry, air-dry and disinfect the shrimp ditch and paddy field. Plant a bunch of aquatic plants alternately every 3 meters, 2 Elodea plants and 3 Hydrilla verticillium plants form a bunch of water plants, distributed in a star shape.

[0041] (2) Shrimp feeding: From March to mid-April, after the aquatic plants take root and germinate, gradually add water to submerge the ends of the aquatic plants by 15 cm, and then put high-quality shrimp seedlings in the shrimp ditch and rice fi...

Embodiment 3

[0054] A kind of method of co-production of shrimp and rice, specifically comprises the following steps:

[0055] (1) Paddy field preparation: From January to February, the paddy field will be divided into 50 mu as a unit, and "L" shaped field side shrimp ditch will be excavated along the outer edge of the field ridge, with a depth of 1 to 1.2 meters and a width of 4 meters. 1:1.5, the ridge is 0.8 meters higher than the field surface, the top is 3 meters wide, and the escape net is set up on the ridge; freeze-dry, air-dry and disinfect the shrimp ditch and rice field, and plant Elodea and Hydrilla verticillium on the shrimp 10-15 days after disinfection. In the ditch and the paddy field, a bunch of waterweed is alternately planted every 5 meters, and 2 Elodea and 3 Hydrilla verticillium are a bunch of waterweed, distributed in a star shape.

[0056] (2) Shrimp feeding: From March to mid-April, after the aquatic plants take root and germinate, gradually add water to submerge t...

Abstract

The invention discloses an integrated lobster-rice farming method, which includes the following steps of: (1) lobster cultivation; (2) lobster seedling release; (3) lobster seedling management; (4) first season lobster catching; (5) rice-lobster farming; (6) second season lobster catching; (7) reserved lobster seedings; (8) rice harvest; (9) lobster wintering. The invention relates to the breedingof fresh-water lobster cultivation with rice planting. The whole process does not use chemical fertilizers, chemical pesticides and hormones to produce ecological, high-quality lobsters and rice. Theeconomic benefit of fresh-water lobster cultivation with rice planting combined model is five thousand yuan more than fresh water alone, and two thousand yuan more than rice cultivation per mu, and fully realizes the green, compound, high-potency and scale of the agricultural industry.

Description

technical field [0001] The invention relates to the technical field of aquatic product cultivation, in particular to a method for co-cultivation of shrimp and rice. Background technique [0002] Crayfish, also known as Procambarus clarkii, is native to North America and was brought into my country from Japan in the 1930s, where it has been in a spontaneous wild state for a long time. Crayfish has swept the country with its unique food culture and consumption patterns. It has grown from the field to the big stage of the urban economy and has become an important aquaculture species in my country's freshwater aquaculture. Its rapid development is unstoppable. Agriculture is the foundation of national economic development. In recent years, with the development of science and technology and policy innovation, my country's agricultural economic benefits have continued to increase. However, the excessive pursuit of economic benefits has greatly increased the amount of chemical fer...
