Embodiment 1

[0024] Choose fields with clean water quality, sufficient water sources, convenient drainage and irrigation, good water and fertilizer retention performance, and not affected by drought or flood. Excavate the fish ditch with a depth of 65cm and a width of 85cm in the shape of a "ten". Excavate Yudang, the depth is 1.3 meters, the area accounts for 6.3% of the paddy field area, and it is rectangular. Yugou is connected with Yudang. The ridges are increased to 60cm and widened to 50cm. Set the water inlet and outlet at the corresponding corners of the paddy field.

[0025] 10 days after the seedlings are planted, the seedlings are released after the seedlings turn green. The seedlings are put in according to the ratio of grass carp, carp and crucian carp at a ratio of 1:1:1. Soak for 5 minutes to disinfect the fish body. 15 kg per mu, 50-100 g / tail per fish.

[0026] Breeding: artificial feeding of rapeseed, bran or compound feed every day; in the early stage of rice growth...

[0029] Choose fields with clean water quality, sufficient water sources, convenient drainage and irrigation, good water and fertilizer retention performance, and not affected by drought or flood. Excavate the fish ditch with a depth of 50cm and a width of 50cm, in the shape of "Tian". Excavate Yudang, the depth is 1 meter, the area accounts for 5% of the rice field area, and it is rectangular. Yugou is connected with Yudang. The ridges are increased to 50cm and widened to 40cm. Set the water inlet and outlet at the corresponding corners of the paddy field.

[0030] 12 days after the seedlings are planted, the seedlings are released after the seedlings turn green. The seedlings are put in according to the ratio of the number of grass carp, carp and crucian carp at 1:1:1. Soak for 3 minutes to disinfect the fish body. Put 20 kg per mu, 50-100 g / tail per fish.

Abstract

The invention belongs to the technical field of agricultural ecology and particularly relates to a method for raising fishes in a paddy field. The method comprises the following steps: A, selecting a piece of paddy field: selecting the field with clean water, sufficient water source, convenient irrigation and drainage, good water and fertility retention performance and no drought and flood influence; B, rearranging the piece of paddy field: digging a fish ditch with the depth of 50-80cm and the width of 50-100cm; digging a fish pit with the depth of 1-1.5m and the area accounting for 5-8% of that of the paddy field; connecting the fish ditch with the fish pit; heightening and reinforcing a ridge; forming a water inlet and a water outlet in the corresponding corners of the paddy field; C, raising the fishes: starting to throw fingerlings after rice seedlings turn green 7-15 days after seedling transplantation, wherein the fingerlings are thrown according to a quantity ratio of grass carp to common carp to golden carp of 1 to 1 to 1 and 10-20kg of the fingerlings are thrown per mu; and D, performing raising management. The method is easy to implement and high in fish yield per mu.

Description

technical field [0001] The invention belongs to the technical field of agricultural ecology, and in particular relates to a method for raising fish in paddy fields. Background technique [0002] China is the first country in the world to carry out freshwater fish farming. The oracle bone inscription unearthed from the Yinxu site in Anyang, Henan Province has a record of "fishing in the garden, November", which shows that the earliest pond fish farming in China has a history of more than 3,000 years. Rice field fish farming is an important part of freshwater fish farming. It refers to a production form that uses the shallow water environment of rice fields supplemented by artificial measures to grow rice and fish to improve the production efficiency of rice fields. Rice-fish farming in China has a long history and practical experience that continues to this day. However, in today's industrialized world, the development of fish farming in rice fields has been relatively slow...
