How to cultivate Loach out of season

In the plastic big boron cement pond, the farmers in our town cultivate Loach out of season, especially when the sales price is high during New Year's Day and Spring Festival, the price difference is 3-5 yuan, and the benefit is considerable. Now the culture technology is introduced as follows.

First, the conditions for the construction of pools. Depending on the respective courtyard, the area of the cement pool should be 100-150 square meters. The Loach pond is built on the ground, underground or semi-underground, and has an inlet and outlet with a depth of 1.2-1.5 meters, a drain 30 cm from the bottom of the pool, and anti-escape facilities, with a depth of 0.8-1 m. Before releasing Loach, 20 cm thick mud was put in advance, and the Loach pond was cleaned and disinfected 10-15 days before stocking. After 7 days, add water 20-30 cm, put 0.3-0.5 kg of livestock and poultry manure per square meter, and then add water to 40-50 cm. A few days later, when the water color is yellowish green and the transparency is 15-25 cm.

Second, greenhouse installation. It is built according to the method of setting up the vegetable greenhouse, with single-layer or double-layer structure, bamboo pole can be selected as the material, steel bar structure can be used if conditions permit, and appropriate straw mats or curtains should be prepared to cover the plastic greenhouse for heat preservation in winter.

Third, stocking Loach. Misgurnus anguillicaudatus is usually soaked in 5% salt water for 3-5 minutes before stocking to prevent water mildew and eliminate body surface parasites. The density is about 25 kg per cubic meter of water. With the increase of the stocking amount, the weight of the fish increases, and the water in the pond can be deepened to 0.8-1 m (if you have the conditions, you can keep the micro-running water in the pond, the effect is better). When the Loach enters the pool, it is also necessary to prevent the temperature difference from being too large, so as not to cause the Loach to catch a cold and cause death.

Fourth, feeding and management. Misgurnus anguillicaudatus is omnivorous, with small crustaceans, aquatic insects, snails, earthworms, animal offal, algae, rice bran, bean dregs and so on. When feeding, pay attention to the reasonable collocation of animal and plant bait, and the feeding should be determined. No investment is allowed when the water temperature is higher than 30 ℃ or lower than 10 ℃. In feeding, we should pay attention to fertilization, sprinkle manure into the Loach pond every 4-5 days, 50-100 grams per square meter, keep the transparency of the water 15-25 cm, and change the water in time, and change the water twice a week. 30 cm each time (if there is micro-running water in the pond, it is not necessary to change water frequently, but to prevent the deterioration of water quality). The tanning pool should always be filled with tap water so that there is plenty of water.

Fifth, greenhouse management. According to the requirements of agricultural technology, refer to the key points of vegetable greenhouse management.
