Embodiment 1

[0024] A kind of cultivation method of rice crab symbiosis, comprises the following steps:

[0025] Step 1: Set up ditches with a depth of 30 cm and a width of 70 cm along the inner wall of the paddy field ridge, and then dig out a plurality of flow ditches with a depth of 65 cm and a width of 20 cm evenly in the paddy field. 18% of the area of ​​the paddy field. There is a water delivery port on the ditch. The water delivery port is connected to both ends of each flow channel. A diversion pipe for water flowing out of the rice field is provided between adjacent flow channels. Isolation net for crab escaping, the diversion pipe is 20~30cm away from the ditch, and the ditch is equipped with an isolation fence to prevent rice field crabs from escaping;

[0026] Step 2: Spread quicklime on the surface of the paddy field 10-15 days before transplanting, the amount of quicklime is 500kg / hm², and apply farmyard manure to the paddy field 10-12 days after spreading the quicklime, the ...

[0031] A kind of cultivation method of rice crab symbiosis, comprises the following steps:

[0032] Step 1: Set up ditches with a depth of 35 cm and a width of 60 cm along the inner wall of the paddy field ridge, and then dig out a plurality of flow ditches with a depth of 70 cm and a width of 15 cm evenly in the paddy field. 15% of the paddy field area, there is a water delivery port on the ditch, and the water delivery port is connected to both ends of each flow ditch. There is a diversion pipe for water flowing out of the paddy field between the adjacent flow ditch, and the diversion pipe is provided to prevent the paddy field. Isolation net for crab escaping, the diversion pipe is 20~30cm away from the ditch, and the ditch is equipped with an isolation fence to prevent rice field crabs from escaping;

[0033]Step 2: Spread quicklime on the surface of the paddy field 10-15 days before transplanting, the amount of quicklime is 600kg / hm², and apply farmyard manure to the padd...

Abstract

The invention discloses a culture method for rice and crab symbiosis in the field of ecological aquaculture. The culture method comprises the following steps that 1, a rice field water inlet-outlet channel and an isolation net are arranged; 2, rice field processing is performed before rice seedling transplantation; 3, a crab hiding place is arranged; 4, juvenile crabs are put and processed; 5, daily rice field management is performed. Water, rice, crabs and water hyacinths are integrated into a mutual relevant body by arranging the rice field water inlet-outlet channel, the crab hiding place and the isolation net, then performing rice field disinfection treatment before rice seedling transplantation and putting a proper quantity of juvenile crabs and water hyacinths, growth of rice and crabs is promoted, and the rice field yield per unit area is remarkably improved.

Description

technical field [0001] The invention relates to the field of ecological aquaculture, in particular to a rice-crab symbiotic breeding method. Background technique [0002] Rice is native to China and has a planting history of more than 7,000 years in my country. The fruit of rice is paddy. After the paddy (grain) is shelled, it is called rice, fragrant rice, and rice. Because rice can be eaten in a variety of ways, such as rice, rice porridge, rice cakes, rice cakes, rice wine, etc., it is also nutritious. , The characteristics of fragrant and sweet smell make nearly half of the world's population feed on rice. [0003] However, due to the extensive use of chemical fertilizers and pesticides in the rice production process, the rice field environment is generally polluted, which poses a huge threat to the high yield and safe production of rice. The use of a large number of agricultural chemical products has also caused the destruction of biodiversity in rice fields, the accu...
