Rice, crayfish and lotus symbiosis mode

Abstract

The invention provides a rice, crayfish and lotus symbiosis mode. Ridges with the width of 2.0 m and the height of 1.0 m to 1.5 m are built around a rice, crayfish and lotus base; lotus root surrounding ditches with the width of 4.0 m and the depth of 0.8 m are dug in the surrounding ridges, water drainage pipes are arranged on one sides of the surrounding ridges, water inlet pipes are arranged onthe other sides of the surrounding ridges, ridges with the width of 0.5 m and the height of 0.5 m are built around the interiors of the lotus root surrounding ditches, and rice fields are arranged inthe ridges; in March, April and May every year, 40-50 kg of young crayfishes are put into each mu of rice, crayfish and lotus base; 200-300 lotus root seedlings are planted in each mu of lotus root surrounding ditches in March and April every year; after large commercial crayfishes are caught and sold in June every year, water is added to plant rice seedlings, the crayfishes are returned into thelotus root surrounding ditches to continue to be bred, and a large number of commercial crayfishes and seed crayfishes can be caught and sold in July, August and September every year; and fruit treesor landscape trees can be planted on the surrounding ridges. The rice, crayfish and lotus symbiosis mode has the beneficial effects that the acre yield is increased, land resources per inch are reasonably used, and the personal safety of deep-water operation farmers is ensured.

Description

technical field [0001] The invention belongs to the field of agricultural planting and breeding, and in particular relates to a symbiotic model of rice, shrimp and lotus. Background technique [0002] At present, rice planting and crayfish farming in rural areas are combined. The method is the rice-shrimp co-cropping model. This rice-shrimp co-cropping model has been widely promoted in rural areas, and the economic benefits are much higher than the previous simple rice planting or simple shrimp farming. However, there are still many shortcomings in the rice-shrimp co-cropping model, such as the waste of field resources, and in the rice-shrimp co-cropping, the ditches around the fields are dug relatively deep, mostly at a depth of more than 1 meter, and farmers often have problems in launching into the water. The harm of personal safety aspect occurs, and there is no feasible technical solution for this defect at present. Contents of the invention [0003] After years of e...

This rice-shrimp co-cropping model has been widely promoted in rural areas, and the economic benefits are much higher than the previous simple rice planting or simple shrimp farming. However, there are still many defects in the rice-shrimp co-cropping model, such as the waste of field resources, and in the rice-shrimp co-cropping, the ditches around the fields are dug relatively deep, mostly at a depth of more than 1 meter, and farmers often have problems when they go into the water. Hazards to personal safety occur, and there is currently no feasible technical solution to this defect
