Description

TECHNICAL FIELD

[0001] The present application relates to the field of crayfish culture, and particularly relates to a device for culturing crayfish in rice field in off-season. BACKGROUND

[0002] Crayfish is one of the main aquatic products for integrated rice-fish culture in China, and the culture area has been increasing in recent years. At present, the culture area of crayfish in China is mainly concentrated in the middle and lower reaches of the Yangtze River, and the five traditional culture provinces of Hubei, Anhui, Hunan, Jiangsu and Jiangxi still occupy an absolute dominant position. However, the culture mode, stocking and catching time of crayfish in these regions are relatively synchronous, resulting in obvious seasonal fluctuations in the supply of crayfish market, mainly showing over-supply and low price in summer and autumn, and under-supply and high price in winter and spring. Therefore, the off-season culture of crayfish has great market prospects. Guangxi is located in Lingnan and has prominent subtropical climate conditions, and the air temperature is within the growth and breeding range of crayfish all year round. The minimum temperature in winter is about 10℃, and the duration is not long, which can ensure the normal feeding and growth of crayfish, and has the climate advantage of off-season culture.

[0003] Although the temperature in Guangxi in winter and spring is not very low and has little effect on the normal feeding and growth of crayfish, crayfish is a burrowing animal and prefers to build nests in the relatively cold climate. On the one hand, the dikes can provide a limited hole-digging site, which affects the breeding efficiency; on the other hand, the hole-digging of crayfish can damage the dikes. At present, the culture in Guangxi mainly refers to the mode in Hubei, and a surrounding ditch is dug around the four sides to widen the dikes with the soil of the surrounding ditch for the needs of hole-digging of crayfish in off-season culture. However, more than 80% of the rice fields in Guangxi are mountainous and hilly areas, and the plough layer is thin, which is not suitable for ditch digging. At the same time, by the end of March, the rice field is drained for the preparation of planting early rice, and a large number of crayfish will dig holes in the rice field to escape from catching. During the growth of rice seedlings, crayfish will gnaw the roots of rice, which will damage the rice seedlings and cause a reduction in grain yield. If there are too many crayfish, the rice yield will be zero. In addition, the catching of crayfish in rice field usually mainly relies on manual catching, that is, laying traps in the field. On the one hand, the overall weight of the trap is large, and it is time-consuming and laborious to catch. In winter and spring, the water temperature is low, which is not suitable for manual catching. SUMMARY

[0004] In view of the problems in the prior art, the present application provides a device for culturing crayfish in rice field in off-season, which reduces the hole-digging of crayfish in dikes and the probability of hole-digging of crayfish in rice field when the rice field is drained for the preparation of planting early rice at the end of the culture period, and also realizes automatic catching.
