The invention relates to an ecological paddy-field soft-shelled turtle culture method, which comprises the steps of paddy field selection and preparation, soft-shelled turtle fry stocking, feeding and daily management and common soft-shelled turtle disease prevention and control. During the paddy field selection and preparation, a paddy field which is in a low-lying terrain, has a good water source condition and smooth water flow and is convenient to drain and irrigate is required; a soft-shelled turtle trench is excavated in the paddy field, the upper width of the soft-shelled turtle trench is 3m, the bottom width and the depth of the soft-shelled turtle trench are 1.5m, the length of the soft-shelled turtle trench is determined according to the area of the paddy field and the length is preferably to account for approximately 20 percent of the total area of the paddy field; and a sand beach is built in the center of the paddy field, the length of the sand beach is 5m, the width of the sand beach is 1m and the sand beach is 0.8m higher than normal water level. The invention provides an ecological three-dimensional rice planting and soft-shelled turtle culture technical operation line, which is mainly based on rice planting and takes soft-shelled turtle culture as auxiliary. On one hand, the paddy field provides a good place for the growth of the soft-shelled turtles. On the other hand, the excrement of the soft-shelled turtles and food debris are used as organic fertilizers for rice. When the rice absorbs the fertilizers and grows, an effect of purifying an impoundment is taken, the soft-shelled turtles can loose soil in the paddy field and catch injurious insects, the quality of the soft-shelled turtles is effectively improved and the economic benefit is improved.
