Problems solved by technology

[0002] Crayfish, also known as Procambarus clarkii, red crayfish and freshwater crayfish, are freshwater economical shrimps. They are widely welcomed by people because of their delicious meat. Crayfish have become an important economic breeding species in China in recent years, and the market price is getting higher and higher. High, the demand is increasing, which drives the development of artificial breeding. At present, there are few crayfish in paddy fields. Due to improper use of breeding methods, the output of lobsters is small, the meat quality is poor, and the survival rate is low. At the same time, artificial feeding has a lot of feed, which not only increases the cost of breeding, but also deteriorates the quality of lobsters, and cannot be sold at a good price. Some farmers use too many pesticides and fertilizers, which not only reduces the quality of lobsters, but also pollutes water resources and soil. , not conducive to sustainable development

Embodiment 1

[0015] A method for cultivating rice and shrimp, comprising the steps of:

[0016] (1) Select paddy fields: paddy fields with good water quality, sufficient water volume, no pollution sources around, strong water retention capacity, convenient drainage and irrigation, and not subject to flooding should be selected. Set up filtering and anti-escape nets, excavate a circular shrimp breeding ditch around the inner side of the paddy field ridge, the ditch is 1.6 meters wide and 0.8 m deep, and excavate a field ditch in the middle of the field. The field ditch is 1.5 meters wide and 0.5 meters deep, and the circular shrimp ditch The area of ​​Hetianjian ditch accounts for about 10% of the paddy field area;

[0017] (2) Ditch cleaning and disinfection: 15 days before the shrimp release, the circular ditch and field ditch must be cleaned, the floating soil should be removed, and the collapsed ditch wall should be repaired. Use 50 kg of quicklime for each mu of paddy field circular sh...

Embodiment 2

[0023] A method for cultivating rice and shrimp, comprising the steps of:

[0024] (1) Select paddy fields: paddy fields with good water quality, sufficient water volume, no pollution sources around, strong water retention capacity, convenient drainage and irrigation, and not subject to flooding should be selected. Set up filtering and anti-escape nets, excavate a circular shrimp breeding ditch around the inner side of the paddy field ridge, the ditch is 2 meters wide and 1.1m deep, and excavate a field ditch in the middle of the field. The field ditch is 1.8 meters wide and 0.7 meters deep, and the circular shrimp ditch The area of ​​Hetianjian ditch accounts for about 12% of the paddy field area;

[0025] (2) Ditch cleaning and disinfection: 17 days before the shrimp release, the circular ditch and the field ditch must be cleaned, the floating soil should be removed, and the collapsed ditch walls should be repaired. Use 60 kg of quicklime for each mu of paddy field circular ...

Embodiment 3

[0031] A method for cultivating rice and shrimp, comprising the steps of:

[0032] (1) Select paddy fields: paddy fields with good water quality, sufficient water volume, no pollution sources around, strong water retention capacity, convenient drainage and irrigation, and not subject to flooding should be selected. Set up filtering and anti-escape nets, excavate a circular shrimp breeding ditch around the inner side of the paddy field ridge, the ditch is 1.8 meters wide and 1 m deep, and excavate the field ditch in the middle of the field. The field ditch is 1.7 meters wide and 0.6 meters deep. The field ditch area accounts for about 11% of the paddy field area;

[0033] (2) Ditch cleaning and disinfection: 16 days before the shrimp release, the circular ditch and field ditch must be cleaned, the floating soil should be removed, and the collapsed ditch wall should be repaired. Use 55 kg of quicklime for each mu of paddy field circular shrimp ditch, or use other drugs to thorou...
