Comprehensive ecological planting and breeding method for crayfishes, soft-shelled turtles, fishes and ducks in rice field

Abstract

The invention relates to a comprehensive ecological planting and breeding method for crayfishes, soft-shelled turtles, fishes and ducks in a rice field, and belongs to the technical field of agricultural breeding and planting. The comprehensive ecological planting and breeding method comprises four stages of rice field preparation, rice field fish and crayfish polyculture, rice, soft-shelled turtle and fish co-culture and rice harvesting and duck stocking. In the first stage, an annular ditch is dug around the rice field, and a fish collecting pit is formed in one side of the annular ditch; food tables are uniformly distributed in the annular groove; anti-escape walls are arranged on the periphery of the rice field on the outer side of the annular ditch; a surrounding net is arranged on the periphery of the fish collecting pit; then cleaning and disinfecting, aquatic plant transplanting, and water fertilizing are carried out; and then breeding operation is carried out from the second stage to the fourth stage. According to the comprehensive ecological planting and breeding method for the crayfishes, the soft-shelled turtles, the fishes and the ducks in the rice field, the space-time resources of the rice field are fully utilized, produced agricultural products are diversified, the space-time resources of the rice field in the next half year are fully utilized on the basis of rice and the crayfishes, the yield of high-quality agricultural products such as soft-shelled turtles, fishes and ducks is increased, and the economic benefit is 2-3 times that of an original rice and crayfish planting and breeding mode.

Description

technical field [0001] The invention belongs to the technical field of agricultural breeding and planting, and in particular relates to a comprehensive ecological breeding method for shrimps, soft-shelled turtles, fish and ducks in paddy fields. Background technique [0002] At present, my country's comprehensive rice-fishery breeding mode mainly includes rice shrimp, rice soft-shelled turtle, rice crab, rice fish, rice loach, etc., and the rice-fish breeding mode is the main one, accounting for more than 50% of the rice-fishery comprehensive farming area. Since 2015, the market price of freshwater crayfish in my country has increased steadily. Driven by the market's pursuit of profit, the scale of crayfish farming in my country has rapidly expanded. In 2019, the total farming area reached 19.26 million mu, and the annual output reached 2.09 million tons. Balance, the seasonal supply of commercial shrimp is obviously oversupply, the overall price of commercial shrimp is decli...

Problems solved by technology

[0003] In order to solve the problems of difficult control of seedling density, low utilization rate of space-time resources in paddy fields, low efficiency of biological control of diseases and insect pests, and side effects of returning full amount of straw to the field in the traditional rice and shrimp farming mode, the present invention provides a paddy field shrimp, soft-shelled turtle, fish, etc. , comprehensive ecological breeding method for ducks
