Abstract

The invention discloses a predacious diving beetle breeding site which comprises a paddy field planting area 1, an annular ditch 2, an anti-escape shed 3 and a ridge 4. The paddy field planting area 1has the area of 300-1000 m<2>, the annular ditch 2 is 0.5-1.0 m wide and 0.3-0.5 m deep, the anti-escape shed 3 is 3.2-3.7 m high, and the ridge 4 is 1-2 m wide and 0.5-0.8 m high. The invention further discloses a predacious diving beetle breeding method. The method includes the steps of establishing the predacious diving beetle breeding site, cleaning the annular ditch, conducting disinfecting,water injecting and fertilizer applying and planting aquatic plants in the beginning of April, stocking breeding predacious diving beetles in the last ten days of April, conducting plowing in the last ten days of May, planting rice seedlings in the beginning of June, putting the breeding predacious diving beetles in the annular ditch and then starting to feed the breeding predacious diving beetles, and regularly changing water. The traditional paddy field planting mode is changed, and the comprehensive productivity level of a paddy field is improved; the predacious diving beetles stocked in the paddy field have weeding, pest removing and fertility increasing effects, production cost is saved, water quality conditions are improved, and pollution is reduced.

Description

technical field [0001] The invention belongs to the field of comprehensive breeding of fish and rice, and in particular relates to a method for cultivating dragon lice. Background technique [0002] Dragon lice are Insecta, Coleoptera, Carnivorous suborder, Dragon Liceidae ( Dytiscidae ) is a general term for this type of insects. There are more than 4,000 known species in the world, and more than 230 species have been recorded in China, which are distributed all over the country. In my country, the yellow margin dragon ( Cybister japonicus Sharp ) is the most common, and other common ones include Japanese sucker louse, three-spotted dragon louse, golden dragon louse, black dragon louse, black dragon louse, and oriental three-spotted dragon louse. [0003] The main value of dragon lice is that it can be used as medicine and food. Its edible part exceeds 80%, the protein content in the body is as high as 23.8%, the fat content is only 3.6%, and the ash content is 9.2%. ...
