Environment friendly pond composite efficient plantation and cultivation method for soft shelled turtle-vegetable-rice

Abstract

The invention discloses an environment friendly pond composite efficient plantation and cultivation method for soft shelled turtle-vegetable-rice. The method is based on cycle economics and ecological principles, combining nutrition physiological and environmental adaptability characteristics of soft shelled turtles, aquatic vegetables and rice and without occupying land resource, two different agricultural production techniques of soft shelled turtle breeding and aquatic vegetable and rice plantation are combined through ingenious ecological designs to realize harmonization of efficient utilization of aquaculture pond space, significant promotion in economic benefits, improved aquaculture environment and aquatic product quality. In this method, the breeding parameters of Trionyx sinensis, aquatic vegetable and rice are based on comparative experiments, which can realize the normal growth of the three, and obtain better economic benefit; at the same time, aquatic vegetables and rice can purify water, reduce water nutrient salt load, regulate water temperature, improve the aquaculture environment, thereby the frequency of changing water is reduced and the quality and safety of aquatic products are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an environment-friendly pond turtle-vegetable-rice compound high-efficiency breeding method. Background technique [0002] Soft shelled turtle, commonly known as soft-shelled turtle, water fish, turtle and tortoise, etc., is an oviparous reptile that lives amphibiously on land and water. It is an important aquaculture species in my country. Because of its delicious meat, rich nutrition, high edible and medicinal value, it is very popular among consumers. In recent decades, due to overfishing, deterioration of the living environment, and loss of habitat habitat, the wild natural population of soft-shelled turtles has shown a sharp decline. In order to meet the growing dietary needs of the common people, artificial breeding of soft-shelled turtles has developed rapidly in the past two decades. [0003] At present, my country's soft-shelled turtle breeding mainly a...

Problems solved by technology

There are the following main problems in the traditional cultivation method of pond turtles with high density, high bait feeding rate and high water exchange rate: 1) the survival rate is low, the breeding cost is high, the breeding space is fully utilized, and the comprehensive economic benefit is low; 2) breeding The environment is poor, there are many diseases in the breeding species, and the fishery medicine is frequently used, so it is difficult to guarantee the quality and safety of aquatic products; 3) The amount of water exchange is large, and the waste of water resources is serious; 4) The nutrient load of the breeding water is high, and the arbitrary discharge of breeding wastewater has a negative serious pollution

To improve water quality and sediment conditions by changing water and dredging, at the cost of polluting the environment, it will be difficult to maintain a production method that simply pursues high density and high output; Quality requirements are also increasing, and aquatic products whose quality and safety cannot be guaranteed will be eliminated by the market
