In order to obtain the success of the artificially cultivated Astragalus membranaceus and the high yield and high efficiency, the first one is to keep the ecological requirements of Astragalus membranaceus feeding. I. Advantages of the ecological breeding of Astragalus membranaceus Using the ecological breeding method to raise Astragalus has high density, high yield, and high efficiency. Each square meter can produce 6-8 kg of astragalus, the yield per mu can reach 3-5 million. This method of breeding astragalus is not only easy to achieve success, but also less labor, low cost, high efficiency, but also can get the same taste as wild astragalus. Second, the conditions of the ecological breeding Huangpi (1) water source pollution-free, suitable size of natural ponds, and pond water must be fresh and dry all year round. (2) It is best to see ponds in which wild astragalus has been grown or can raise (have) other fish. (3) The pond must be able to enter water, drain water, and prevent escape. Third, the method of ecological breeding Huangpi (1) election pond. According to the requirements of selecting ponds, ponds that are too large (above 50 mu), difficult to manage, and unable to escape should not be used. Generally, a pond with 0.2 mu to 6 mu is better. About 1-2 acres is best. (2) The whole pond. Well-chosen ponds should be properly trimmed. Through sorting, it is possible to improve water quality, facilitate feeding and management, and facilitate the growth of Scutellaria baicalensis. The finishing is mainly the removal of rancid sludge and garbage around the pond. (3) Clear pond. Use 10 kg to 20 kg of fresh lime per acre, and pour evenly into the whole pool before stocking. (4) Stocking. Clear ponds are stocked after 20 days. About 10 grams of seedlings are stocked with 50-80 kg per acre. Artificially cultivated seedlings can be fed directly to the pond. When you are stocking for the first time, you must choose the same size seed. Later, seedlings can no longer be seeded by natural breeding. The types of bait are quail, fly maggots, small fish, and astragalus feeds. (5) Management. It is mainly anti-escape. When the rainfall is heavy, it must be drained in time. Use a wire fence for the inlet and outlet. In addition, due to high stocking density, we must pay more attention to anti-theft and phytotoxicity. (6) Prevent disease. Eco-cultured jaundice is generally not susceptible to disease. Dozens of oysters are stocked per acre and most diseases can be prevented. (7) Fishing. The method of cage trapping is mainly used. At night, it is caged and caged in the morning. The implementation of catching up and keeping small, annual breeding, one-time restocking, benefit each year. Macheng City Special Aquatic Research Institute supplies high-quality, high-yielding sorghum seedlings for 56 years at 56 yuan per kilogram, spawning quail, 80 yuan per kilogram.
