(4) arrange water chestnut before the arrival of high temperature season in late July, start water to arrange water chestnut. Cut off the small water chestnut discs with a diameter of less than 20cm just out of the water in time, and be careful not to hurt the large water chestnut plates that have entered the flowering stage, and straighten the chaotic water chestnut plates that have been overturned by wind or animals to ensure smooth flowering result.

During the daytime when the weather is calm, soft-shelled turtles often lie on the sunny bank to bask in the sun (being commonly called as basking in the back), utilize the ultraviolet rays in the sunlight to kill the pathogenic bacteria on the body surface, promote the healing of the injured body surface, increase body temperature by basking in the back, and promote The food is digested, and the balcony is a place for the soft-shelled turtle to bask.

The harvest of Nanhu water chestnut is selected mid-term picking (generally when gathering for the 3rd-5th time), has the characteristic characteristic of Nanhu water chestnut variety, and fruit is fully ripe, can sink into the bottom of water rapidly through water selection, and fruit is big, full and full , the fruit shape is correct, and there is no obvious damage by diseases and insect pests as a kind of water chestnut. Kinds of water chestnuts should be stored in net bags in water to ensure safe overwintering.

When water temperature rises to more than 20 DEG C, start throwing and feeding bait, regularly will throw something and feed bait and be placed on the feed table close to the water surface, water temperature is different, and the number of times of throwing something and feeding is different, such as, high temperature season (such as summer) can be e...

Abstract

The invention relates to the field of aquaculture, in particular to an ecological soft-shelled turtle breeding method. The method includes the steps of selecting a shallow pond or a river bend or a low-lying paddy field to serve as a soft-shelled turtle breeding pond; arranging escape prevention fencing walls on the periphery of the breeding pond, wherein the breeding pond is provided with a water inlet and a water outlet, the water inlet is higher than the water surface, the water outlet is lower than the bottom of the pond, and escape prevention nets are arranged on the water inlet and the water outlet respectively; arranging a fodder platform and a sunbathing platform on the breeding pond, wherein a sunshade is arranged above the fodder platform; planting trapa acornis in the breeding pond, wherein the planting area of the trapa acornis is half to three fourths the area of the breeding pond; breeding young soft-shelled turtles in the breeding pond after the turtles are disinfected, enabling the water temperatures to rise to be above 20 DEG C, and regularly throwing fodder to the soft-shelled turtles so that the soft-shelled turtles can be bred. According to the ecological soft-shelled turtle breeding method, the soft-shelled turtles and the trapa acornis grow in the same breeding pond, the body color of the bred soft-shelled turtles is especially black and bright, the meat of the bred soft-shelled turtles is firmer, and quality is obviously improved.
