Mixing breeding method of fish and duck in paddy field

Abstract

The invention discloses a mixing breeding method of fish and ducks in a paddy field and relates to a comprehensive utilizing method of planting and breeding, which comprises the following steps: (1) preparing the paddy field, ditching a ditch with the depth of 50-120cm and the width of 30-120cm in the paddy field and digging a pit with the depth of at least 120cm, the width of at least 180cm and the length adapted to the length of the south end of the paddy field at the south end of the paddy field, wherein a pit opening is as high as the bottom surface of the ditch; filling water till water height is 10-30cm above than the surface of the paddy field; (2) three days after seedlings are planted in the paddy field, breeding 15 to 18 ducklings per mu at the breeding time between sunrise and sunset each day; (3) five days after the seedlings are planted in the paddy field, breeding 50-150 kilograms of fish fries per mu once; (4) before harvest, draining the water in the paddy field, leading all fishes to enter the pit and acquiring the fishes; (5) after the fishes are acquired, breeding a duck every day; after rice is harvested, keeping breeding the duck every day and feeding rice grains left in the field; and after the rice grains are eaten up by the duck, acquiring the duck. The invention improves the utilization benefits of the farmland and increases the economic income of farmers.

Description

technical field [0001] The invention relates to a method for comprehensive utilization of planting and breeding, in particular to a breeding method for mixing ducks and fish in paddy fields. Background technique [0002] At present, with the acceleration of industrialization, the per capita cultivated land in rural areas tends to decrease. It is difficult to increase the income of farmers with the single use of cultivated land. When farmers plant rice, a large number of flying insects or flying insect larvae will breed in the rice fields, and these flying insects or flying insect larvae will eat rice seedlings and affect the harvest. In this regard, farmers mainly rely on pesticides to kill. On the one hand, the use of pesticides requires costs, and on the other hand, the use of pesticides will pollute rice and affect the health of eaters. Contents of the invention [0003] In view of the above problems, the present invention provides an ecological comprehensive breeding...
