Feed selection of soil yuan for culture

The diet of Tuyuan is very miscellaneous and its feed sources are wide. Feed includes plant feed and animal feed. Among them, plant feed can be divided into green feed, cereal feed and cake (meal) feed, which is the main feed for breeding soil element.

Vegetal feed green feed lettuce, cabbage, rape, pumpkin, loofah, wax gourd, watermelon peel, potato, carrot, all kinds of wild vegetables, grass, leaves, crop stems and leaves, and apple, pear and other fruit peel can be used as feed for Eupolyphaga, of which mulberry leaves, dandelion, lettuce, pumpkin, carrot and so on are the most commonly eaten green feed for Eupolyphaga. Grain feed has wheat bran, rice bran, sorghum, corn, etc., these are also the main feed for feeding earth element at present. Among them, wheat bran is the main one, which can be fed raw in general. If it is fried, steamed and cooked, it has a slight fragrance, and the earth element is more fond of eating and the feeding effect is better. Cake (meal) feed such as bean cake, bean curd residue, peanut cake, sesame cake, rapeseed cake, etc. This kind of feed is rich in protein, although it is not the main feed, but it is not optional. Cake meal feed has a greater role in promoting the yield of Eupolyphaga. Animal feeds include fish meal, bone meal, silkworm chrysalis powder, small fish, shrimp and all kinds of animal debris, earthworms and so on. Adding this kind of feed can promote the rapid growth of soil element and shorten the breeding cycle. It is a very good feed. Common feed formula larvae feed bran 65%, bean cake or soybean powder 20%, green feed 10%, fish meal or bone meal 5%. The feed of three-year-old soil element is wheat bran 40%, corn flour 10%, bean cake or peanut cake 5%, green feed 40%, fish meal or bone meal 5%. 30 percent of wheat bran, 10 percent of corn flour, 10 percent of cake, 45 percent of green feed and 5 percent of fish meal of soil element over nine instars. In a word, the feed of Tuyuan is varied, and the formula should be mastered flexibly. Only reasonable collocation and scientific formula can lay a good nutrition foundation for the growth and development of soil element, and achieve high yield and high efficiency in the future.
