1. Indiscriminate purchase of seed. At present, the artificial propagation technology of jaundice in China has not yet reached the level of mass production. Many so-called “artificial breeding†or other so-called “high-quality†seedlings purchased by farmers in other places are actually collected wild seed species. The holding and multi-link storage and transportation operations are unscientific, and the mortality rate can reach 90% to 100% for breeding. Therefore, be sure to carefully identify when purchasing seedlings. In general, artificially cultivated jaundice should purchase high-quality seeds locally.
2. Unmatched variety. From the aspect of appearance, there are many types such as deep yellow spot, red spot, light yellow spot, and fine green spot. Only the first two kinds of scutellaria have the faster growth rate, and artificial breeding can achieve the desired economic benefits.
3. Size polyculture. In the same pool (cage), the size of the yellow crickets is polytrophic, and the young crickets do not dare to compete for food and the physique gradually weakens or even dies. When there is not enough food, jaundice can eat each other. Therefore, when the size of astragalus polyculture, although the speed of rapid growth, but the overall output is too low.
4. Pool water is too deep. Because the body structure of Astragalus is flawless, it cannot float in different water layers, and it must expose the surface of the air 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 strength, which affects the growth of normal life. According to the size of the carcass, the depth of the carcass should range from 5 to 20 cm. The cages should be filled with water and weeds should be filled with the entire cage to provide good habitat and breathing conditions for the eel.
5. Indiscriminate application of manure. Dianchi Lake has a small body of water, and manure fertilizer can easily damage water quality and induce disease.
6. Ignore the cultivation of aquatic plants. Aquatic grass can provide heat preservation and cooling for Astragalus membranaceus, purify water quality, and provide excellent hiding places for Astragalus membranaceus. Dianchi without aquatic plants cannot create a good ecological environment. It is also difficult to cultivate jaundice and it is difficult to achieve high yields and high benefits.
7. Partial "prime" lack of "deterrence." Some farmers use wheat bran, vegetable cakes, bean dregs, rice, green vegetables and other plant foods to feed the yellow peony, jaundice is severely hungry, and it will be swallowed when there is a lack of bait. However, its nutrition can not meet the needs of the life activities of jaundice, let alone On growing weight gain, jaundice will gradually become thin and die. Astragalus is a ferocious, fleshy, flesh-eating fish that should be fed animal feed or full-priced compound feed.
8. Frequent refueling. Breeders often have unsafe food because they are caught in the east, often changing feed types. Astragalus eat a certain degree of fixed bait, suddenly change the type of bait, jaundice is difficult to adapt and refuse to eat, except to change the feeding, will affect normal life. If you need to change the variety of bait should be fed with the original feed, and gradually reduce the proportion of the original bait, while increasing the proportion of new bait to adjust.
