Freshwater fish paddy field cultivation techniques

The cultivation of fish, shrimp, crab and other special aquatic products in paddy fields can not only produce 400-500 kilograms of pollution-free high-quality rice per acre, but also increase the collection of special aquatic products such as fish, shrimps and crabs by more than 50 kilograms, and increase economic income by more than 1,000 yuan. Farming of shrimps and crabs in paddy fields creates a three-dimensional symbiotic, benign cycle ecological environment. Paddy fields provide a good habitat for fish, crabs and crabs, and rich natural foods. In addition, organic fertilizers and bio-pesticides are used for paddy field cultivation. Fertilizers and pesticides not only reduce costs, but also reduce pollution, which is conducive to farmland environmental protection and people's health. The development of paddy fields has broad prospects.
1. Estimated investment per mu (1) 450 yuan for field project (2) 150 yuan for escape prevention and anti-stealing facilities (3) 700 yuan for crab, shrimp, and fish fry (4) 200 yuan for bait, fertilizer, and medicine (5) Salary for personnel, Total tax and fee 300 yuan to invest 1800 yuan
2. Analysis of profit per acre (1) Production of fish, shrimp, crab and other aquatic products 60 kg, of which special water 50 kg (2) Production value Special aquatic products 50 kg 60 = 3,000 yuan Fish 10 kg 5 = 50 yuan Subtotal 3050 yuan (3 ) Profit 3050-1800 = 1250 yuan
3, the main technologies and measures:
One is the selection of paddy fields, which is infiltration and drainage, and drainage is convenient. The second is to do a good job in the construction of field projects, and excavate the ditch, field ditch and holding pool. The area of ​​farming ditch accounts for about 25% of the total paddy field area. Built to prevent escape and steal facilities; Fourth, a reasonable stocking of seedlings, a mu loose deduction crab 1000, 10,000 shrimp seedlings, 30 species of fish; Fifth, the bait feed, adhere to the "meat combination, green combination" The sixth principle is water quality regulation, and the persistence of constant exchange of new water; seventh is the prevention of rice diseases as the main priority; (1) selection of disease-resistant, insect-resistant, and lodging-resistant rice varieties; (2) a good job of disinfecting seeds for seed soaking; (3) Seedlings, seedlings, planting, expansion, and sparse planting; (4) seedlings are planted before delivery; and (5) timely field curing; (6) drug control, biological and low-toxicity pesticides, spray method, and medicine hand Change the water.

In order to make full use of Goji resources in Ningxia and deeply exploit the medicinal health care value, this year, the company started the deep-processing projects of high purity Goji polysaccharide and black Goji Anthocyanin, which have been identified as the Model processing enterprises of Chinese Goji Berry by the local government.
