Paddy field leech mixed-culture method

Abstract

The invention discloses a paddy field leech mixed-culture method which includes the steps of paddy field selection, rice inserting planting, leech fry throwing, raising management, paddy field fertilization and the like. Based on an existing leech culture technology, a green environment-friendly leech culture technology combined with rice planting is provided, effective measures are taken according to local conditions without occupying extra land resources, the existing culture technology and methods are integrated, a culture management mode integrating rice planting and leech culture is built by the aid of the ecology principle, leech culture cost is obviously reduced, the economic benefit of unit land area is greatly improved, and the quality and the yield of leeches are ensured.
