Is oily lettuce lettuce leaves? Oily lettuce is not lettuce leaves

Oily wheat cabbage is a kind of green leafy vegetable that has swept the market in recent years, it is a variant of lettuce, there are two types of pointed leaves and round leaves, the leaf color is bright and tender green, the stems and leaves are edible, it still maintains crisp green and fragrant after stir-frying, and can also be used as a soup, which is quite popular in the market. The cultivation of oilseed and wheat rape has the following three characteristics: one is that the pests and diseases are light, so pesticides are rarely used, it is a safe and healthy vegetable, and the second is that the requirements for the growth environment are not strict, the growth period is short, the cultivation is easy, and it can be cultivated regardless of the tube shed or the open field. It has a unique flavor, contains a lot of vitamins and a lot of calcium, iron, protein, fat, vitamin A, VB1, VB2 and other nutrients.

Absolutely not, there are two kinds of lettuce, one is a leaf shape that is very similar to lettuce leaves, and the other leaf shape is different, but it is a different thing from lettuce leaves.

It doesn't seem to be, but my mother bought lettuce leaves yesterday and came back, and I feel that the taste is different.

What a coincidence. I also thought about this question today after researching it, and it wasn't.

Oily lettuce is not lettuce leaves. Oilseed lettuce is a variety of lettuce leaves, with a smooth surface, long lanceolate, a refreshing taste, and a lot of dietary fiber and water. The surface of lettuce leaves is uneven, inverted-lanceolate, oval or elliptic, inverted-lanceolate, with an acutely pointed and rounded apex, containing a large amount of carotene.

The leaves of lettuce are relatively slender, while the leaves of lettuce are a little wider. The leaves of lettuce are relatively rough to eat, and the lettuce is relatively delicate; Oilseed lettuce contains a lot of vitamins and nutrients such as calcium, iron, protein, fat, vitamin A, VB1, VB2, etc., and the nutritional value is slightly higher than that of lettuce leaves.

Oilseed lettuce, lettuce of the Asteraceae family.

The leaves of rape are long lanceolate, and its appearance is a bit like the "head" of lettuce, the leaves are slender and flat, and the bamboo shoots are thin and short. Its properties are heat-resistant, cold-resistant, adaptable, cold-resistant, moisture-loving, resistant to diseases and pests, sweet and brittle quality, less fiber, and the growth temperature is 20 25, which is distributed in China.

Lettuce leaves are native to temperate regions such as China, India, and Japan. Asteraceae lettuce, an annual herbaceous plant with wrinkled leaves. Rich in vitamins and carotene, people usually only eat the stems when eating lettuce, but in fact, lettuce leaves are more nutritious.

The differences between lettuce and lettuce leaves are as follows:1. Different varieties. Although lettuce and lettuce leaves are both a type of lettuce, lettuce belongs to leaf lettuce, and lettuce leaves are the leaves of stem lettuce, so these two vegetables are completely two different varieties, which is also the biggest difference between lettuce and lettuce leaves.

2. The shape is different. There are many differences between lettuce and lettuce leaves in the leaves, and the lettuce is not only thin, but also particularly long, which is very similar to the slightly part of the leaves on the tip of lettuce, which is lanceolate, while the leaves of lettuce are only very thin, and its length is not as long as the leaves of lettuce.

3. The taste is different. There is also a big difference between the taste of lettuce and lettuce, and the taste of lettuce is crisp, tender, fragrant, and refreshing, especially oyster sauce and lettuce, which I like to eat the most. In comparison, the taste of lettuce leaves is much inferior, not only is it not fragrant or crispy, but it also has a bit of astringent and bitter taste, so few people generally eat lettuce leaves, just eat the stems of lettuce.

Even if you eat it, it is occasionally used to make soup.

1. The shape is different

The leaves are slender and smooth; The leaves of lettuce are wider, the meridians on the leaf surface are prominent, so they appear uneven, and the leaves are not as long as those of lettuce.

2. Different varieties.

Lettuce is a kind of lettuce and lettuce leaves, but lettuce belongs to leaf lettuce, and lettuce leaves are the leaves of stem lettuce, and lettuce leaves have a number of different varieties, such as round-leaved lettuce, sharp-leaved shoots and purple-leaved shoots are all important components of it, but oily lettuce does not have these varieties.

3. The taste is different.

If you miss the best time to eat, the leaves will begin to age, and the bitter and astringent taste will be stronger, but the stem of lettuce will taste more crisp.

4. Different ways to eat.

Oily wheat cabbage can be eaten raw, cold, or cooked before eating, and it is also very suitable for stir-fried or stewed soup. The flesh of lettuce is relatively tender, and the stems and leaves can not only be eaten raw, but also fried or pickled.

The head of the vegetable is much smaller than the head of the lettuce, and the leaves are basically the same! I used to buy vegetables as lettuce, but when I looked at the size of the head, I knew it was different!

The leaves of lettuce are slender; The canola leaves are round and thick!

The diameter of the lettuce is thick and large! And the diameter of the lettuce is only a little bit!

The leaves of lettuce are much greener than lettuce leaves!

Canola and lettuce are not the same type of vegetables, and the parts of the leaves on the top of the lettuce are very similar.

Canola can't be squeezed for oil, the thing that can be squeezed for oil is rapeseed, which is its seed.

Botanically speaking, lettuce belongs to the lettuce for stems in lettuce. Lettuce can be eaten cold, cooked and pickled, and is cultivated throughout the country. Lettuce stems are not a very nutritious vegetable.

However, lettuce leaves are much more nutritious than lettuce stems. Lettuce contains fat, carotene, B1, B2, calcium, phosphorus, iron, etc., which are relatively high in vegetables. According to the shape and color of the leaves, lettuce can be divided into three types: round-leaved shoots, sharp-leaved shoots and purple-leaved shoots.

Oilseed wheat cabbage is a chrysanthemum, which is a sharp leaf type leaf with young shoots and young leaves as products, and the leaves are long lanceolate, and its appearance is a bit like the "head" of lettuce, the leaves are slender and flat, and the bamboo shoots are thin and short.

From the perspective of blood relationship, oily lettuce belongs to a variant of leaf lettuce - long-leaf lettuce, which is similar to the familiar lettuce, so it is also known as cow lettuce. Its color is green and strong. Disease resistance, strong adaptability, crisp and tender texture, extremely tender taste, fragrant, known as "phoenix tail".

The surface of the lettuce leaves is smooth, and the surface of the lettuce leaves is uneven, but the lettuce belongs to a variety of leaf lettuce and is the romaine lettuce.

1. The difference between lettuce and lettuce leaves: In terms of appearance, lettuce and lettuce leaves are still very different. The leaves of lettuce are slender and the surface is relatively smooth, while the lettuce leaves are relatively wide, and there are many meridians protruding from the surface, which is relatively uneven, and the lettuce leaves are not as long as those of lettuce.

2. Lettuce and lettuce leaves are both lettuce plants, but lettuce is a variant of leaf lettuce - long-leaf lettuce, which has higher nutritional value than stem lettuce; Lettuce leaves, on the other hand, are the leaves of stem lettuce, so lettuce leaves are only one component of stem lettuce.

3. The taste of oily wheat cabbage is more delicate and crisp, while the lettuce leaves are not so refreshing, there may be a little astringency, and the taste is not as good as oily lettuce.

4. There is also a difference between lettuce and lettuce leaves in terms of nutritional value. Oilseed lettuce contains more dietary fiber and vitamins, which has a good effect on moisturizing the intestines, detoxifying and nourishing the skin; Lettuce leaves, on the other hand, contain a lot of carotene, which is good for relieving eye fatigue and preventing night blindness.

Oily lettuce is not a leaf of lettuce. Lettuce is a lettuce of the Asteraceae family, and lettuce leaves are the leaves of lettuce. Because it is a kind of sharp leaf in lettuce, there are not many varieties, and the most used pure sesame oil and wheat cabbage is introduced from abroad.

China's research on oilseed and wheat rape started late, and there are no particularly good varieties.

The germination temperature of rapeseed is 15 20, and in order to emerge neatly, it is best to carry out germination treatment before sowing. Put the seeds into a mesh bag, soak them in water together with the mesh bag for 5 or 6 hours, take them out, drain the water, wrap them in a wet towel or gauze, etc., and promote germination at room temperature in the season when the temperature is suitable.

The root system of oilseed wheat is shallow, the absorption capacity is weak, the leaf area is large, and the water consumption is large, so it likes moisture and avoids dryness. After planting, water enough rooting water, according to the weather conditions, in case of continuous sunny days, 2 3 days after should be watered once to slow the seedlings, at any time to pay attention to the situation of the seedlings; After slowing the seedlings, combined with cultivating and loosening the soil, the root system can be promoted.

1. The difference between long-leaf lettuce and lettuce 1. Difference between varieties Although lettuce and lettuce are both lettuce plants, lettuce has a long history of planting, and we often ate it when we were children, and it is one of the most common vegetables in our impression. Oilseed lettuce is a popular vegetable in recent years, it is a variety of leaf lettuce, called long-leaf lettuce, because of the longer leaves, high nutritional value, more popular in the market, has gradually replaced lettuce. 2. The difference in appearance is very easy to distinguish from the appearance, their leaves are still different, oilseed lettuce is long-leaved lettuce, so its leaves are relatively slender, and the surface is relatively smooth, and the color is blue-green.

The leaves of lettuce are relatively wide, and there are many meridians on the surface that are protruding and uneven, and the leaves are not as long as those of oily lettuce, and the color is dark green. But their stems are the opposite, with the stem of lettuce being short and thin and generally not edible, while the stem of lettuce is long and thick and edible. 3. The taste difference is that the taste of lettuce is more delicate and crisp, while lettuce is not so refreshing, and there is a trace of bitterness, if you miss the best time to eat, the leaves will age, these bitterness will be stronger, and the taste of the stem of lettuce is crisp.

4. Nutritional differences: Oily lettuce and lack of coarse lettuce also have a certain difference in nutrition, oily lettuce is rich in dietary fiber, vitamins and other nutrients, which is higher than lettuce, and has the effect of intestinal laxative, detoxification and beauty. Lettuce, on the other hand, contains a lot of carotene, which can relieve eye fatigue and has a good effect on preventing night blindness. 2. How to choose lettuce 1, look at the leaves Lettuce leaves should be green and tender, not dry and yellow Fuhong Town, under normal circumstances, if the leaves of lettuce are very green, it can mean that the lettuce is very fresh, fresh lettuce has more water and a good taste, so freshness is the first element of good lettuce.

2. The lettuce is fresh and has a lot of water, and it should have a certain hardness when it is held, and when it feels a little soft, it means that it has lost too much water for so long, that is, it is not fresh enough. 3. Look at the cross-section lettuce is divided into two kinds, one skin is very thick, and the other skin is very thin, which can be seen through the cross-section. Normally, the skin is thin and there is a clear distinction between the skin and the flesh, and this lettuce tastes very crispy when it is fresh, and the skin does not take up too much weight.

4. Look at the color of the lettuce meat and whether it is hollow Some lettuce looks very good, especially when it is fresh, but it can't stand up to scrutiny. If you look at the meat of lettuce, you will find that some of them are dark green and some are blue-yellow, and this green food is naturally green and dark, which needs to be noted.
