Symbiotic culture method of shrimp, soft-shelled turtle and rice

Abstract

A symbiotic culture method of shrimps, soft-shelled turtles and rice comprises the following steps: (a) selecting five or more mu rice fields as a feeding pool of shrimps and soft-shelled turtles, ditching on the periphery of the feeding pool and arranging soft-shelled turtle escape-proof devices on the edges of the ditches at the depth ranging from 80 to 120 centimeters, wherein the percentage of the ditches in the feeding pool is ranging from 20% to 30% per mu; (b) sowing rice seeds in June with the density of rice transplanting ranging from 70% to 80% and managing the rice fields in a conventional way after rice transplanting until the rice is harvested in the first ten-day period of November; (c) breeding shrimp species in a free-range manner, particularly putting shrimps with shrimp eggs weighing 1 to 1.5 kilograms per mu in the rice fields in May and putting baby shrimps weighing 5 to 7.5 kilograms per mu in the rice fields in July; (d) breeding soft-shelled turtle species in a free-range manner, particularly putting in 15 to 25 baby soft-shelled turtles weighing 125 grams to 175 grams per mu in the rice fields in April, collecting and enabling the soft-shelled turtles to come into season at the Spring Festival. The symbiotic culture method of shrimps, soft-shelled turtles and rice is a kind of recycling economy and an environmental-friendly cultivation technique in a high-quality and efficient environment. Accordingly, freshwater shrimps are fed in the rice fields, soft-shelled turtles are put in a shrimp feeding pool, the shrimps eat injurious insects in the rice fields, the soft-shelled turtles eat baby shrimps bred by the shrimps and feces of the shrimps are absorbed by the rice. The symbiotic culture method is a high-quality, efficient and clean culture production chain.

Description

technical field [0001] The invention relates to a method for symbiotic culture of shrimp and turtle rice, belonging to the technical field of artificial culture of shrimp and turtle. Background technique [0002] The existing techniques of artificially raising shrimp or soft-shelled turtles are quite mature, but the quality of the shrimp or soft-shelled turtles cultured by different farming techniques is different. At present, it has been developed into mixed farming of shrimp and soft-shelled turtles. This mixed farming technology is mainly It is formulated based on the growth characteristics of shrimp and soft-shelled turtles. For example, soft-shelled turtles mainly crawl on the bottom of the pond, while prawns live in the middle and lower layers of the water body. The mixed culture of shrimp and soft-shelled turtles effectively uses the vertical space of the pond; in terms of feeding habits, soft-shelled turtles only swallow large pellets of feed, Shrimp can eat the resi...

Problems solved by technology

[0003] However, there are differences in specific breeding steps in the existing shrimp and turtle mixed culture methods, that is to say, the quality of mature shrimp and turtles obtained by different culture methods is also different, and the level of this quality is reflected in the survival rate, breeding cost, The size of mature shrimp and turtles, etc.
