Embodiment 1
[0029] Embodiment 1: (see figure 1 ) The paddy field culture method of the alpine area of the present embodiment of the perch gordoi pond, carry out according to the following steps:
[0030] 1. In Bohai Town, Dongning City, Heilongjiang Province, the length is 60m, the width is 30m, and the area is 1800m 2 Three rectangular fish pits with a length of 20m and a width of 2m are set in parallel in the paddy field, each fish pit has a depth of 1.5m and an area of 40m 2 ; The total area of the three fish pits accounts for 6.7% of the paddy field area;
[0031] 2. Transplant clusters of reeds into each fish pit to put in artificial fish nests, and the number of artificial fish nests in each fish pit is 4; the fish nests can provide effective shelters for C.
[0032] 3. Add fermented chicken manure water to the fish pit 15 days after transplanting rice seedlings in the rice field, and then select 45.6 kg of healthy, disease-free, and highly active fingerlings of Snakehead go...
Embodiment 2
[0043] Embodiment 2: (see figure 2 ) The paddy field culture method of the alpine area of the present embodiment of the perch gordoi pond, carry out according to the following steps:
[0044] 1. Set up two fish pits and one fish ditch in the paddy fields of Bohai Town, Dongning City, Heilongjiang Province. The fish pits are connected by a fish ditch in the middle. Among them, the rice field is 60m long, 30m wide and 1800m in area. 2 , the length of two rectangular fish pits is 20m, the width is 2m, the depth of each fish pit is 1.5m, and the area is 40m 2 ; The depth of the fish ditch is 0.5m, the width is 0.5m, and the length is 40m. The total area of 2 fish pits and 1 fish ditch accounts for 5.6% of the paddy field area;
[0045] 2. Transplant clusters of reeds into each fish pit to put in artificial fish nests. The number of artificial fish nests in each fish pit is 3; the artificial fish nests can provide effective shelters for C.
[0046] 3. 10 days after transpl...

Abstract
The invention discloses a rice field culture method suitable for Perccottus glenii in an alpine region, and relates to a rice field fish culture method. The method aims at solving the technical problem that an existing rice field fish culture method cannot meet the rice field culture requirement of the alpine region. The method comprises the steps that fish pits or fish pits and fish ditches are formed in a rice field, aquatic plants are planted in the fish pits to be used for putting artificial fish nests, fermented chicken manure fertilizer water is put into the fish pits firstly after riceseedlings are transplanted in the rice field, then fingerlings are put into the fish pits, and bait is supplemented once every 30 days after the fingerlings are put into the fish pits; after the ricefield is harvested, the water level of the rice field is raised to 18-22 cm above the soil plane, the water level is controlled to 10-20 cm above the soil plane of the rice field before overwintering,and fresh bait is put into the fish pits before the rice field water is frozen; and in the overwintering period, ice surfaces of the fish pits and the fish ditches are kept transparent, bait is thrown again after unfreezing in the second year, and fishing is conducted before rice field turning. Compared with fishing and selling before freezing, the method has the advantages that the total economic benefit is increased by 40%-50%, and the method can be applied to the field of rice field culture in the alpine region.
Description
technical field [0001] The invention relates to a method for raising fish in a paddy field. Background technique [0002] Perccottus glehni (Perccottus glehni) belongs to the family Channaidae and belongs to the genus Perccottus glehni, commonly known as "old man fish". The fish has commodity characteristics such as "delicate meat, delicious taste, unique taste, and few spines". With increasing consumer demand, this fish has become a special breeding object with great potential. [0003] my country has a long history of rice field fish farming and is the first country in the world to develop rice field fish farming. After years of practice, rice field comprehensive planting technology has achieved remarkable results. General paddy field integrated planting and breeding method is to throw fry simultaneously when paddy field transplants seedlings, paddy rice and fry grow synchronously, catch adult fish when harvesting rice and drying the field. This method is suitable for a...
