Artificial breeding of Astragalus has always been a hot topic for farmers. For the ideal breeding effect, the following six points must be noted. I. Temporary rearing and selection of seedlings should be strictly controlled. The majority of farmers are affected by the price difference between autumn and winter and the spring and summer peak seasons. They believe that “Huang Biao’s life†has blindly built a large number of temporary acquisitions of astragalus, due to lack of basic breeding techniques. The acquired Huang Biao died in large numbers in the short term. The main reason for this was that most of the acquired yellow locusts were injured and they were infected with pool infections that caused the hydromycosis. At the same time, long-term, high-density transport, a considerable number have all had a fever, coupled with pesticide poisoning and electro-trapping of astragalus mixed in, making farmers at a loss. The correct method is to first observe the color of the captured or acquired skin, test its strength, and inspect the wound. The healthy skin of the jaundice body is bright and smooth, the mucus is uniform, and there is no injury or residue. The head, tail, and anus are normal. Swollen, mucous shedding, anal swelling, or traumatic jaundice will all be eliminated; then "normal" sputum will be placed in 3%-5% saline solution for 3-5 minutes to disinfect the seedlings, where it shoots out of the basin or sinks to the pelvic floor. For love activities, the yellow cricket that is caught by the hand should be eliminated. The yellow cricket that can swim freely in the pot can be used. Second, maintain a good permeability to the ground Many farmers adopt a roof or a closed cement pond to raise earthworms, impeding the permeability of the earth's gas. The construction of Dianchi Lake should be able to prevent escape, water injection and proper water seepage. In order to facilitate the geothermal exchange, the bottom of the pool should be covered with bricks instead of fully plastering cement mortar. Third, to prevent the size of the same pool of mixed oysters because of eating small evil, the pool area should not be too large, otherwise feeding, disinfection, water change and other management inconvenience, more importantly, the pool is too large to reach é³The seedlings are fed in batches in stages, which can easily lead to large eating, especially in the case of insufficient feed, resulting in serious losses. Fourth, to create a good water quality and environmental water, some farmers only pay attention to changing the water, neglecting the pH of water and water, resulting in many pathogenic factors. The water for raising fish should be kept on the basis of "fat, live, tender, and cool". The pH must be maintained at a pH of 6-8. Test strips can be used for testing. If the value is less than 6, apply lime to the tank; if it is greater than 8, sprinkle vinegar solution or dilute hydrochloric acid solution to the tank for adjustment. When changing the water, pay attention to the temperature of the water. The difference between the water temperature and the temperature of the water in the pool should not exceed 3 degrees. Otherwise, the yellow locust is susceptible to colds. Fifth, attention to summer temperatures and dissolved oxygen to regulate the summer temperatures hot, high temperatures, easy to damage the ecological environment of Dianchi Lake, leading to the death of fever caused by yellow fever. Therefore, rich aquatic plants should be cultivated on the Dianchi Lake to facilitate shading and provide a hidden environment. It is beneficial to clean the water and effectively increase the oxygen in the water body by stocking a suitable amount of loach in the Dianchi Lake (accounting for 10% to 15% of the weight of the carp). Also should change the water frequently, the water temperature should be controlled below 30 degrees, and in the summer it should be covered with a shade net. Six, pay attention to scientific feeding methods Many farmers do not understand the food of Astragalus, blindly fed rice, bran, wheat bran, the results of the Astragalus eat less or do not eat at all. Astragalus feed should be used in combination with insect feed larvae, fly maggots, mealworms, etc., animal viscera, waste and self-mixed feed fish meal, flour, cocoon, soybean meal and other plant feeds. Huang Xie, who had just entered the pool, should do a good job training food, feed active insect diet first, and then gradually add other feed to achieve gradual, in order to enable the rapid growth of Astragalus.
