Known as the "vegetable queen" who feeds pigs, the turtle has a relatively high fiber content. High calcium content and calcium-phosphorus ratio. So I chose it as the main course. From the point of view of traditional Chinese medicine, sweet potato leaves are soft, not bitter, easy to feel full, and can also promote gastrointestinal peristalsis and prevent constipation. Conducive to the good excretion of soft-shelled turtle.

In addition, the composition of sweet potato leaves was analyzed: according to laboratory analysis, the crude protein content of stem tip was 21.1%-15.1%of dry weight, which was equivalent to that of pig beef. Protein of stem, leaf and shoot tip is 2.7%, carotene 5580 international unit/100g, vitamin C 4 1.07mg/kg, calcium 74mg/kg, iron 4mg/kg, vitamin b 1 3mg/kg and nicotinic acid 6-/kloc. According to the detection of China College of Preventive Medicine, compared with celery, Chinese cabbage, spinach, Chinese cabbage, rape, leek, cucumber, eggplant, carrot and tomato, among the 14 nutrients, protein, fat, calorie, cellulose carbohydrate, calcium, iron, phosphorus, carotene, vitamin C and vitamin.

2. Cabbage (Cabbage, Cabbage)

This dish is quite nutritious, containing a lot of vitamin C, cellulose, carbohydrates and various minerals. In addition, cabbage also contains vitamin U, which many players will choose as one of the staple foods. I usually increase the content of Chinese cabbage in winter. Moreover, this dish has a good effect on the formation of turtle dung and is more suitable for young turtles.

Step 3: carrots

Carrots are rich in carotene (carotene can regulate the stomach and enhance the appetite of turtles), which is rich in nutrition and is known as "Little Ginseng". Carrots are rich in sugar, fat, volatile oil, carotene, vitamin A, vitamin B 1, vitamin B2, anthocyanin, calcium, iron and other nutrients. However, as the food for turtles, the main problem is that the proportion of calcium and phosphorus in carrots is not high, and they can only be used as side dishes. Because the oxalic acid content of cooked carrots is much less than that of raw carrots, it is recommended to dry them for turtles after cooking.

4. Purple cabbage (purple cabbage)

It is also a nutritious vegetable, which is usually sold in large supermarkets. According to the determination, every 100g of fresh vegetables contains 0. 1 1mg of carotene, 0.04mg of vitamin B 10.04 of vitamin B2, 39mg of vitamin C, 0.3mg of nicotinic acid, 4% of sugar and 65438 of protein. I usually choose one or two leaves as a side dish.

5. oil wheat vegetables

The first thing to say is that this is a strange dish, which is the favorite dish of merchants and the dish that players sneer at most. Many players think it has no nutritional value, and merchants use it only because it is palatable. However, if you carefully observe the composition of oil-wheat vegetables, you will find that oil-wheat vegetables contain a lot of vitamins and a lot of nutrients such as calcium, iron, protein, fat, vitamin A, VB 1, VB2, etc. But the fiber content is low and the water content is high, so it is good to choose a small part as a side dish, not as a staple food.

6. Lettuce; lettuce

This is also a dish that merchants like to use very much, and players are the most scornful. Many players think that it has no nutritional value, and the reason why merchants use it is nothing more than palatability. But if you look at the ingredients of lettuce carefully, it is also low in fiber content and high in water content, so you can only choose a small part as a side dish, not as a staple food.

7. Chinese cabbage

This is a very common dish in our daily life. In terms of composition, its calcium-phosphorus ratio is more than 2: 1, which is still good, but it has high water content and low fiber content, and can only be used as a side dish in a small amount.

8.pumpkin

Pumpkin suggestion is the same as carrot. Generally turtles like to eat, so be careful not to overdo it. This kind of food also includes sweet potatoes.

9. Flammulina velutipes

This is also a nutritious vegetable. In particular, the content of vitamin B is very high and its nutritional value is excellent, so it can be used as a side dish.

Vegetables that can be mixed with a small amount are: cauliflower leaves, rape, Chinese cabbage, fungus, lettuce leaves, celery leaves, chrysanthemum, Chinese kale, shepherd's purse, radish leaves, green pepper leaves, shepherd's purse, Shanghai green vegetables, oil wheat leaves, spinach leaves, tender bamboo shoots leaves and tender corn leaves. ...
