The cultivation of Astragalus mongolicus is also one of the special aquaculture operations, and the income derived from economic activities is higher than that of fish farming. Therefore, in rural aquaculture, the number of households raising Astragalus mongolicus has been expanding in recent years, but there are also many farmers in raising astragalus roots. It is a failure. There are many reasons for checking it. However, there are eight main types of technical problems. Indiscriminate purchase of so-called “artificially-breeded†seed or many other so-called “high-quality†seedlings cultivated and cultivated outdoors, is actually a collection of wild seed species, and these seedlings are not scientific due to temporary conservation and multi-linkage storage and transportation. Operation, the mortality rate in culture is between 90% and 100%, so when buying seedlings, we must carefully examine and identify. Unless the varieties are viewed from the outside, there are deep yellow spots, large red spots, light yellow spots, and fine spots of green spots. Only the first two species are selected to have a faster growth rate, and artificial breeding can achieve the desired economic benefits. The size of polyculture in the same pool in the size of polyculture, small crickets did not dare to fight for food and physical weakness or even death. When there is not enough food, the big quail swallows the small quail so that it grows in size. Although the larvae grow fast, the total pond production is low. The water in the pool is too deep because of the absence of fleas in the body of the scutellaria. It cannot float freely in different water layers to expose the surface to breathe air. The water in the pool is too deep, and the jaundice needs to swim to the surface frequently to breathe and consume a lot of physical energy, which affects the growth of normal life. The pond should have a depth of 5-20 cm depending on the size of the carcass, and the cages should be filled with the entire cage to provide good habitat and breathing conditions for the yellow praying mantis. Dianchi Shi manure fertilizer Dianchi pool water is small, Shi manure is very easy to damage the water quality, induced disease, so "improved water quality" is worth the candle. Ignoring the cultivation of aquatic plants can reduce the temperature of the yellow peony sunstroke and purify water quality. Dianchi without aquatic grasses cannot create a good ecological environment. It is also difficult for aquaculture to succeed, or it is difficult to achieve high yields and high profits. Feeders of vegetarian foods use wheat bran, vegetable cake, bean dregs, rice, green vegetables and other vegetarian foods to feed jaundice. When they are severely hungry and lack food, the jaundice will devour a small amount, but nutrition can not meet the needs of the activities of jaundice. Not to mention growth and weight gain, it has long caused the jaundice to gradually become thin and die. Astragalus is a ferocious benthic carnivorous fish, should be fed animal feed or full-priced compound feed. Frequent restocking is often caused by farmers without bait due to bait, often changing feed types. Astragalus feed should have a certain degree of stability, suddenly change the type of feed, jaundice is difficult to adapt and refuse to eat, will affect the normal production growth.
