Problems solved by technology

However, due to serious water pollution, the quality of wild crayfish has been seriously affected; at the same time, overfishing of wild resources and backward artificial breeding techniques have caused the degradation of germplasm resources and the decline in production
In order to meet the market demand, more and more people began to try ecological farming, but the current rice field farming methods and models are improper, and the crayfish produced are generally small in size, poor in color and have many diseases, which makes the survival rate of crayfish Both production and production are affected, and farmers cannot be guaranteed to obtain corresponding economic benefits

Embodiment 1

[0016] (1) Renovation and construction of paddy fields: select the paddy fields where crayfish are cultivated, excavate circular shrimp ditches along the inner side of the paddy fields, use the soil dug out of the circular ditches to reinforce, heighten and widen the ridges, and set up escape nets on the ridges.

[0017] (2) Disinfection of paddy fields: One month before the shrimp seedlings are put in, water is poured into the circular ditch. When the water depth in the circular ditch reaches 50-60cm, use quicklime to disinfect and clear the field. The dosage of quicklime is 100kg / mu, 14-16 After two days, continue to enter the water until the water depth in the paddy field reaches 10-20cm.

[0018] (3) Planting aquatic plants: transplanting aquatic plants in paddy fields and circular ditch. The water depth in the circular ditch is required to be 0.6 meters for the transplanting of aquatic plants in the circular ditch. After 3-5 days, continue to enter the water. The transplan...

[0025] (1) Renovation and construction of paddy fields: select the paddy fields where crayfish are cultivated, excavate circular shrimp ditches along the inner side of the paddy fields, use the soil dug out of the circular ditches to reinforce, heighten and widen the ridges, and set up escape nets on the ridges.

[0026] (2) Disinfection of paddy fields: One month before the shrimp seedlings are put in, water is poured into the circular ditch. When the water depth in the circular ditch reaches 50-60cm, it is disinfected and cleaned with quicklime. The dosage of quicklime is 80kg / mu, 14-16 After two days, continue to enter the water until the water depth in the paddy field reaches 10-20cm.

[0027] (3) Planting aquatic plants: transplanting aquatic plants in paddy fields and circular ditch. The water depth in the circular ditch is required to be 0.8 meters for transplanting aquatic plants in circular ditch. Continue to enter water after 3-5 days. The water depth in paddy field i...

Abstract

The invention discloses an ecological rice-lobster co-culture method. By employing the method disclosed by the invention, end product lobsters of two crops and rice of one crop can be harvested per year, lobster-rice continuous cropping and lobster-rice mixed cropping are organically combined; artificial compounded feeds are employed at different growth stages, so that the requirements of lobsterson nutrients at a rapid growth stage are met, the utilization efficiency of nutritional ingredients of the feeds is also increased, and pollution to culture water caused by remnant feeds and manure is reduced; the planting of rice implements a one-row-planted one-row-emptied mode, and thus, sufficient space and places are provided for the lobsters to enter a rice field for exercise, look for foodand eliminate weeds and insect pests; and meanwhile, a border effect is fully utilized, so that the growth of the rice is promoted, the pesticide application of the rice field is reduced, the planting cost is reduced, and green rice is produced.

Description

technical field [0001] The invention relates to the field of crayfish culture, in particular to a method for ecological co-culture of rice and shrimp. Background technique [0002] Crayfish breeds fast, has a short breeding cycle, and at the same time has delicious meat, rich nutrition, large market demand, broad development prospects, high economic benefits, and widely exists in freshwater ponds in my country. However, due to serious water pollution, the quality of wild crayfish has been seriously affected; at the same time, overfishing of wild resources and backward artificial breeding techniques have caused the degradation of germplasm resources and the decline in production. In order to meet the market demand, more and more people began to try ecological farming, but the current rice field farming methods and models are improper, and the crayfish produced are generally small in size, poor in color and have many diseases, which makes the survival rate of crayfish Both pr...
