Background

Crayfish, also known as procambarus clarkia, red crayfish or freshwater crayfish, is a freshwater economic shrimp, is popular with people because of delicious meat taste, and has become an important economic breeding variety in China in recent years because of eating impurities, high growth speed and strong adaptability. In recent years, as wild resources are sharply reduced and the market demand is continuously increased, the artificial breeding of the crayfishes is popularized in a large area, and the breeding mode and the breeding technology are continuously improved. The method for breeding the freshwater crayfishes in the rice field is an operation mode which utilizes the shallow water environment of the rice field and is assisted by artificial measures to breed rice and shrimp so as to improve the unit area benefit of the rice field. The crayfish enters the rice field, so that the rice cultivation cost can be reduced, and the rice cultivation benefit can be increased. The paddy field is a comprehensive ecological system, and the fertilizer applied to the rice cultivation also provides excellent natural conditions for the growth of other animals and plants in the paddy field while meeting the growth and development of the rice, so that the pure paddy cultivation field needs to weed and kill insects regularly by using medicines. Generally, the pesticide is applied for 5-7 times in the whole rice cultivation period, so that the rice cultivation cost is increased, and the pesticide residue of rice products is caused. After the crayfishes are bred, the crayfishes have super strong adaptability and wide feeding property, all animals and plants except rice in a rice field can be utilized, the invalid consumption of nutrient components caused by the growth of weeds is avoided, the attack of plant diseases and insect pests is reduced, and the medicine cost is greatly saved; frequent foraging activities of the crayfish can break the 'attached algae' on the soil surface of the rice field and seal and fix the oxide layer, so that the decomposition of the fertilizer is accelerated, the soil ventilation is increased, the soil moisture content of the rice field can be improved, the rice yield is promoted, and the benefit is improved. The crayfish is bred in the rice field, the shrimp breeding yield can be increased, and the comprehensive benefit is improved. Therefore, crayfish is cultivated in the rice field, on one hand, the traditional cultivation mode of the rice planting area is changed, and on the premise that the grain planting area is not reduced, the utilization rate of the land is improved, and the output benefit of the rice field is improved; on the other hand, the method utilizes the shrimps to prey on the insects in the rice field, maintains the ecological environment of the rice field and realizes the purposes of shrimp culture and shrimp culture in the rice field.

The existing methods for co-culturing rice and shrimps are more, and the co-culturing is carried out by adopting a mode of opening shrimp ditches in a rice field and constructing escape-proof nets or walls around the rice field. This kind of mode is because the net or the wall of preventing escaping erects on the paddy field, influences daily planting and breeding work, and the net or the wall of preventing escaping that expose also easily suffers destruction in addition, directly influences the effect of preventing escaping. In addition, the shrimp ditches are directly excavated and used according to common ditches, so that the communication between the rice field and the shrimp ditches is inconvenient, and the shrimp ditches are inconvenient to salvage and clear in the breeding process. The problems all affect the breeding efficiency of the rice shrimps directly or indirectly, and prevent the rice shrimp from breeding to achieve the best virtuous cycle of 'breeding the shrimps in the rice field and breeding the rice in the shrimps'.
