One, rice paddy loach how much profit is an acre of land?
1. Input costs
Mainly for seedling and feed inputs, novice farmers should choose specifications for the 3-5 centimeters about the inch seedling is appropriate, at present, the loach inch seedling acre of field needs about 3500 yuan. Feed mainly choose protein content in 36% or more of the floating fish feed, currently breeding a catty loach feed cost is about 4.5 yuan, mu production is generally more than 2,000 pounds, feed costs need 9,000 yuan. Normal epidemic prevention and disinfection and water conditioning supplies need about 500 yuan, water and electricity maintenance, etc. need about 500 yuan. The total **** cost of raising an acre of loach is about 13,500 yuan.
2. Harvest Profit
The loach can generally yield more than 2000 pounds per mu, calculated on the basis of 2000 pounds, then, at the current average wholesale price of 11 yuan market price, you can earn 22,000 yuan. After deducting the total cost of breeding, a mu of loach can earn about 8500 yuan. The breeding cycle of loach inch seedling is about 100 days, and most areas of the country can breed two seasons a year, so a mu of loach can earn about 17,000 yuan a year. At the same time, as farmers continue to improve their breeding techniques, and now more and more self-propagation or purchase of splash seedling breeding, breeding loach splash seedling investment will be less, breeding efficiency will be higher.
Second, the method of rice paddy loach farming
1.field construction
Selecting the field area of about 1.5 acres is appropriate. The paddy field needs to be constructed with ridges, and plastic film buried on the inside of the ridges to prevent them from escaping by drilling holes. The inlet and outlet of the two blocking nets, the outer side of the available polyethylene mesh, the inner side of the metal mesh. The field dug a moderate size of fish slip, fish slip can be square, round or irregular shape.
2. seed stocking
Rotational farming is generally in the early rice harvest, 3-4 days in the sun, per mu of rice bran, rapeseed cake about 130 kilograms, the next day per mu of rotting organic manure 250 kilograms of manure, exposure to sunlight for 4-5 days to make it decay and decomposition, and then water storage, put loach seed; part-time farming is generally in the rice seedling stocking, single season rice stocking Loach species, single-season rice stocking time is appropriate after the first cultivation, double-season rice stocking time, generally in the late rice transplanting, generally about 25,000 seedlings per mu.
3. Feed feeding
Mudskipper seedling stocking, the first month of feeding animal feed and plant feed half of the mixed feed, once a day, each feeding amount of mudskipper total body weight of 3-4%, 1 month later, every 15 days fertilizer 1 time, each time per mu of fermented organic fertilizer about 100 kilograms, and also feeding rice bran, bean cake, and soya bean cake. At the same time feeding rice bran, soybean cake, rapeseed cake, silkworm pupae and other feeds, later you can fertilize the bait in the set of fish pits, which is conducive to the centralized capture.
4. Daily management
Frequent inspection of anti-escape facilities, the water level should be adjusted according to the growth of rice or loach needs at the right time, in the rice tillering before the water level needs to be shallow; rice nodulation period, you can appropriately deepen the water level; in the heavy rains, special attention should be paid to prevent the loach escaped from the field.
China's southern region of the paddy field area, and sufficient water, the most suitable for breeding loach, which can save the area of the waters, but also does not affect the food planting, two birds with one stone, is a more efficient model of loach breeding.
