First, the material method
1. The test site is set at the special farm of Xinjiamiao Temple in Weiyang District. The test pond is made of 2 concrete embankment impervious basins. The area of ​​each pond is 11 mu. The average depth of fish pond is 2 meters in production season, and the pond sludge is 30 centimeters. The water source is groundwater. Pump water injection and drainage, each pond is equipped with a 3-kilowatt aerator.
2. The fish stocks were cleared using the quick-lime dry pond. On March 10, 2001, the seedlings for the production and breeding were put into use. Totally 1900 fish tails (totaling 271.8 kg), specifications 210 g/tail, 1000 catfish (50 kg), 50 g/tail.
3. The formulation and feeding of bait began to acclimate with pellets on March 20th. After one week, the acclimation effect was found to be unsatisfactory. Instead, it was fed in fish ponds and fed three times a day. Two months later, the growth of catfish was found. Fast, the growth of flower buds is slow, and afterwards, the flour, oil dregs, and bran are mixed and ground in time. The fabrics are stirred into a lump together with water, another feeding point is added, and a small amount of granular material is added. Four principles are set to ensure that fish do not eat well. The flower buds floating under the surface of the water rushed under the surface of the water. It would be better for the carp to float on the water to catch food.
4. Fish disease prevention adheres to the principle of “prevention from prevention and prevention from over-regulation.†In addition to the disinfection of fingerlings, from May to September, 20 kg of quicklime is used twice a month to splash water on the whole pool to prevent bacterial diseases. In fish disease prevention work, no dead fish accident occurred.
5, water quality regulation and control of water quality, increase oxygen, disease prevention and other management links. From April onwards, as the water temperature gradually rises, new water is added at any time. With an aerator, the dissolved oxygen is kept above 4 mg/l. And the use of colorimetric detection of water quality, ammonia nitrogen is not more than 0.2 mg / l or less, always ensure that the water quality is excellent, the transparency of the pool water is maintained at about 30 to 35 cm. Take a tour of the pond in the evening and check the growth every 30 days.
Second, the test results
1, the results September 10 fish out of the pond, the total output of 17866 kg, mu average output of 812 kg. Among them, the production of flower pods was 10,279 kg, the yield per mu was 66.4 kg, the trout production was 6,126 kg, and the mu yield was 278.5 kg.
2. The total output value of the product was RMB 114,300, of which, Huayuan was 60,000 yuan, carp 49,000 yuan, and Baizhu 0.53 million yuan; the total cost was 100,000 yuan and total net income was 14,300 yuan.
Third, summary and discussion
1. In recent years, the business of fish head hot pot in Xi’an, Shaanxi Province has been hot, and the price of flower pots is relatively high. It is one of the better breeding methods to actively explore new ways for ponds or reservoirs to cultivate flower buds.
2. Although the primary cultivation of flower buds in the special breeding ponds of the Xinjiamiao Temple has achieved preliminary research, it is mainly due to the fact that the size of the calyx outlet ponds is too small, mainly the density of the calyx. According to the current farming methods, 467.2 kilograms per mu are produced per mu, which is 470 to 500 if calculated according to the weight of 1 kilogram. From the current acre 800 can be adjusted to 500, the pattern for the calyx 500, specifications 250 ~ 500 g / tail, 1000 catfish, specifications 50 g / tail, appropriate adjustment of cauliflower stocking density, to improve the calyx Out of pond specifications.
