Astragalus and loach high-yielding nesting techniques

Astragalus and loach are delicious and nutritious, and they are the best in freshwater fish. In recent years, due to artificial overfishing, pesticide poisoning, and environmental pollution, the resources of natural wild yellow locust and muddy grass have decreased, and the market is in short supply. Therefore, the development of artificial breeding of yellow earthworms and loach has broad prospects. After eight years of research and practice, the Huangqi and Muddy project team at the Mingte Fisheries Research Institute in Macheng City has used the compound feed to feed the yellow cockroach, and the yellow cockroach grows quickly and sets up the loach in the yellow cocoon breeding pond. The benefits are high, and its high-yielding farming techniques are as follows:
First, it is recommended to build a pond that raises yellow peony and a loach in the muddy pond. Choose a pool that can be sheltered from the wind, a quiet environment, and a convenient water source. Cement ponds and earthen ponds can be used. Reservoirs can also be used in reservoirs, ponds, gutters, and rivers. Cage culture. The size of the area is generally 20 to 100 square meters, too big to manage. If cement ponds are used for raising earthworms and earthworms, debasing treatment must be carried out before releasing the seedlings, in order to store yellow seedlings and muddy seedlings. If earthworms are used to raise earthworms and mud, the soil is hard and the bottom of the pond must be compacted. The shape of the rearing pond is determined by the topography. The square can be round, the pool is 0.7-1 meters deep. Whether it is a cement pond or an earth pond, it must be filled with a mud layer at the bottom of the pond, 30 cm thick, containing the organic matter. More fertilizer is better, and it is beneficial for the scutellaria and loach to dig caves. Pay attention to the installation of the inlet when building the pool, overflow, water depth is maintained at 10-15 cm. Water inlets and overflow ports are tied with bar nets to prevent yellow locust and mud lice from fleeing. About 10 days before planting, thoroughly disinfect with lime, and drain water and inject fresh water 3-4 days before planting.
Second, it is crucial to choose the best seedlings for yellow buckwheat and loach seedlings to cultivate yellow buckwheat and loach seedlings. Huangpi seedlings are best cultivated by artificial cultivation of the deep yellow or large brown cantharidin varieties, can not use variegated seedlings and untrained seedlings, but can not believe "super big bang" "Thailand big bang" . The seedlings of Scutellaria baicalensis should be 50-80 pieces per kilogram, which is too small for poor food intake and low survival rate. The stocking density is generally 1 to 1.5 kg per square meter. After 20 days of stocking, the nymphs are stocked with 1/10 of the loach seedlings, and the loach seedlings should be cultured artificially. The survival rate of artificial breeding is high.
Third, feed the compound feed First install the feed table, feed table with a plastic or plastic board will do, the area according to the size of the pool, lower than the water surface 5 cm. Then the seedlings of Scutellaria baicalensis should be put in the first three to six days, so that the Scutellaria baicalensis should be suitable for the environment. The feed should be fed from the 4th to the 7th day. It is best to feed the feed at around 7:00 pm every day. At this time, the feed intake of Scutellaria baicalensis is the highest. Artificial rearing of jaundice is mainly based on feed, and some pupa, locust, and mealworm are properly fed. Artificially trained jaundice, compound feeds and quail are the favorite feeds. The compound feed can use the Yangtze River brand Astragalus full-priced feed or Dajiang Group's Astragalus compound feed, and can also be self-aligned. The formula is: 21% of fishmeal, 19% of cake, 37% of energy feed, and 12% of dried fruit (dry) Minerals 1%, yeast 5%, multivitamins 2%, binder 3%. Artificially cultivated dark yellow large-spotted miao seedlings were fed with this compound feed, and the fed amount was 3-5% of the weight of the scutellaria baicalensis. Feed 1 to 2 times a day (depending on the weather and water temperature). Using the principle of timing, quantitative, 20 grams of astragalus seedlings a year can grow to 200-300 grams, high breeding efficiency. Loach in the pond is mainly eaten by the feces of the yellow crickets and the uneaten jaundice feed. The loach naturally reproduces quickly. When the ratio of the pond loach is more than 1/10, wheat bran can be fed once a day.
IV. Feeding management The growth season for yellow cockroaches and loach is from April to November, and the peak season is from May to September. During this period, the management must be “difficult” and “fine”. Solve; Observe carefully the growth dynamics of the pond's jaundice and loach so that appropriate measures can be taken in time. The habit of jaundice and loach is nocturnal. Keep the water in the pool fresh and the pH between pH 6.5-7.5. The water level is suitable.
Fifth, prevent rickets and prevent rickets. Once the onset of jaundice, the treatment effect is often unsatisfactory. There must be no disease to prevent it first, and there must be a way to prevent it from becoming ill and prevent it from being healed. Can't believe in the lie that "Huang Xi was not sick". Frequent use of 1-2ppm bleach Quanchiposa, regular use of copper sulfate, scorpion disease, squid to stop disinfection of the whole pool to prevent disease, annual spring and autumn with crystal trichlorfon repellent, in the aphid culture pond sets Mudworms can also reduce jaundice diseases. Because muddy grasshoppers are in culture ponds, they like to move up and down, and also eat away the sundries in water bodies, which can purify water and increase oxygen.
