Astragalus breeding refers to the capture of natural seedlings or artificially propagated seedlings, which are placed in specialized tanks for cultivation. As the yellow peony meat is delicious and nutritious, the market price has risen steadily. With fewer and fewer natural resources, the cultivation of astragalus has received more and more attention from people and has become a shortcut for farmers to get rid of poverty and become rich. The national heat of astragalus breeding gradually warms up. At present, there are still certain risks in the breeding of Astragalus, and seedlings, diseases, and feed are still the three major factors that hinder the large-scale development of Astragalus. Although the artificial propagation of Astragalus has been successful, due to the existence of reversal of Astragalus, it is difficult for males and females to distinguish between them, and the amount of spawning of females is not large (200-600 capsules per tail); hatching methods are very unique and it is difficult to carry out large-scale production. , will not get into batches of seed. The eel's slippery and fleeing, especially in the absence of feed, thunderstorms, or deterioration of water quality, are likely to cause a large number of escapes. When escaping, the head quickly moves upward along the shallow water, or the entire body is pulled out. If there is a brick or concrete block around it, it can hook up with the tail and jump out. If there is a hole or drainage channel in the pool embankment, the drainage hole If it is not stopped, the eel is more likely to escape; when it is serious, the eel, which has been raised, can escape from one, leaving it to be an important cause of failure. Therefore, when culturing jaundice, we must attach great importance to the prevention and escape of work. In addition, the preparation of feed is also very important, and the amount of culture should be determined based on the amount of feed. In short, the cultivation of Astragalus membranaceus is driven by the market price, and will be more and more appreciated by people. However, due to the fact that the breeding technology is not mature enough, farmers need to be cautiously engaged.
First, the source of the quail species The source of the quail species is the first problem to be solved in the culture of the jaundice. Currently, the pod species have the following sources.
(i) Captured directly from the wild from April to October each year can be caught in rice fields and shallow water ditches using cricket cages. In particular, there are more jaundice out of hot weather or after thunderstorms, and more in the evening than in the daytime. At 9-10pm in the evening, the cricket cage can be placed at the activity site of Huanghua. When the crickets come out for feeding, they enter the cage by mistake, and because the cage has a barb, it is difficult to get out after entering. At dawn, the cages are taken back and the individuals are sold for large and small for breeding. The fleas captured by this method are healthy without injury, and have a high survival rate. Another method is to turn on the lighting at night and follow the side of the trenches to find out the squid, and catch them with a catch clip or catch them by hand (the middle finger and the ring finger match). At the time of capture, do not injure as many individuals as possible. If the species is not stocked immediately, it can be raised in a container filled with a small amount of water, changing the water once a day, and changing the water 2 or 3 times a day during hot days.
(2) Purchasing Sentence Purchase In the market, we must choose a robust, non-injured jaundice. Astragalus membranaceus caught with hooks has internal injuries in the throat or body surface and is prone to hydromycosis; some do not eat, and the survival rate is low, and they cannot be used as fleas. The emasculated, emaciated jaundice can not be used as fleas. Generally can be divided into three species: the first body color yellow and mixed with large spots, this species grow faster; the second body color yellow, this type of growth in general; third body color Ash, fine spots, the growth is not fast. The three species should be kept separately. The multiplier for the production of quail per kilogram is 1:5-6; the first is 1:3-4; the third is 1:1-2. The species size is preferably 30 to 50 tails per kilogram, the specification is too small, the survival rate is low, and it cannot be listed in the same year; the specification is too large, the meat increase multiple is low, the unit net output is not high, and the economic efficiency is low.
(3) Breeding of semi-artificial seedlings At the end of each year, from the artificially cultivated astragalus, individuals with a strong physique, a tail weight of 100-200 g, and a body with a yellow and shiny appearance are selected and concentrated in an organic-rich loam pool. Overwintering, natural spawning in the spring of the year. When the water temperature in the pool is above 15°C, it is necessary to strengthen the feeding and feeding of this group of carp. During the breeding period, we must pay close attention to the eggs we produce and the hatched seedlings. We find that the eggs can be removed and hatched separately. It is found that the seedlings should be removed in time and stocked in different pools in order to avoid eating too much and eating together. In the cultivation pond, zooplankton may be first cultivated with organic manure such as chicken manure, and then the seedlings will be put in, so that the seedlings will rely on zooplankton for growth. If there is insufficient zooplankton, it can assist in feeding some cooked egg yolk. When young cubs start eating, they gradually disperse their activities. To collect young quail, we can use horse dung, cow dung, and pig dung to mix the soil beforehand in the living waters of the Yellow Seabream to make a blocky distribution of fertilizer and water in the water. A lot of silkworms can grow in the fertilizer and water areas, and the young cubs after eating can be grown. These fertilizers will be automatically drilled into the water, which can be captured with a small net and placed in a larval rearing tank. When the larvae grow to 3-5 cm in the cultivating pool, they can be bred with very finely chopped squid, small scads, and squid. Artificially cultivated quail species generally do not need to be bred when they grow into a cricket, and the growth of eating is better than that of wild quail species. If natural eggs of Scutellaria baicalensis are collected, they should be collected in the deep-water areas of rice fields where they appear. The collection time is usually in the evening or early morning after the thunderstorm, and it is from May to September in the middle and lower reaches of the Yangtze River. Before the oviposition, the females are spawned. First spit bubble nests, commonly known as foam yellow pods. Seeing the bubble means that the females are about to lay eggs. Once the eggs are produced, they can be picked up and transferred to a special incubation pond for hatching.
(d) The artificial propagation of seedlings will be artificially cultivated by artificially propagated seedlings. Seedling cultivation pond should use small cement pool, pool depth of 30 to 40 cm, the upper edge of the ground should be more than 20 cm above the ground to prevent the flooding pool caused by fleeing seedlings. The pool should be set in, drain outlet; and covered with plastic mesh cloth. The pool area is generally not more than 10 square meters. Add 5 centimeters to the bottom of the pond. Per square meter plus cow dung or pig manure 0.5 to 1 kilograms, water depth 10 to 20 cm, the best impregnation silkworm into the pool, the roots of the pool stocking roots must be rich in water hyacinth. 5 to 7 days after the emergence of the seedlings can enter the pool to grow, put 100 to 200 per square meter seedlings. It is best to use silkworms for opening feeds, feed zooplankton, or use animal feed such as minced fish. Astragalus has a habit of eating gluttony and it is important to avoid polyculture when stocking. Usually pay attention to water quality management, often adding new water. After 1 month of feeding, the young can generally grow to about 8 cm. At the end of the year, about 100 tails per square meter can be produced; each tail can reach 15 centimeters in length. About 3 grams of body weight; then you can turn into a breeding pond.
