Introduction: 4,000 pounds per mu, can only grow in the dark, but it is called "gold in vegetables", and it is listed after winter
Leeks are a very common vegetable in our daily lives.
This is also a very popular vegetable among farmers, because it is not only nutritious and delicious to eat, but it also has a characteristic, that is, unlike most vegetables: leeks are planted that can be harvested many times at a time.
Leeks are also known as "lazy vegetables" in the folk, because they are relatively simple to grow, extensive management, and its regeneration ability is very strong, and it will grow after cutting a stubble for a period of time.
And in the folk there is a vegetable, it is the "brother" of leeks, but the planting process can not see the light, can only grow in a dark environment, but its origin is not small, in ancient times is a tribute dish, but also known as "gold in the dish".
After the winter, this dish is on the market again, do you love to eat it? It's leeks!
Don't look at the appearance rate of leeks in the market is relatively high, especially after the winter, it has become a regular customer in the vegetable market, but its price has not been cheap, usually sold to 5-10 yuan a catty, if it is around the Spring Festival, the price is higher, it is simply more expensive than meat.
The cultivation and consumption of leeks in China has a very long history, it is said that as early as the Han Dynasty, some people have been planted and eaten, and folklore is also related to Zhuge Liang.
One year Zhuge Liang led his army to fight, passing by a place and finding that there was a landslide in front of him and he could not move forward. So they stopped, and the soldiers found a yellow-colored wild vegetable on the side of the road and told Zhuge Liang the news.
After Zhuge Liang came to check it out, he found that this was a field of leeks, and these yellow wild vegetables were the leeks buried under the stone. At that time, I picked it to make vegetables and ate it, and found it very delicious, so I began to grow leeks from then on.
So how are leeks grown? Why is it so much more expensive than leeks?
Leeks are actually the same vegetable as leeks, but the method of cultivation is different. Leeks are leeks that have been softened and then allowed to grow in a dull environment.
Because it has been growing in the dark and does not see sunlight, it has not formed chlorophyll during growth, which also causes its color to be yellow, not green like leeks.
Don't look at this unique lightless environment to grow leeks, its status is not low, in ancient times there is also the "emperor of leeks" reputation, also referred to as "leek emperor".
This is because compared with leeks, leeks are not only excellent in terms of nutrition, but also taste better. Because its leaves are softer, it tastes softer.
At the same time, leeks have a spicy taste, but the leek emperor is different, not only does not have a spicy taste, but also a little sweet, the aroma is more intense. Even many people who do not like to eat leeks are also in love with the leek emperor.
Don't look at the leek emperor looks very ordinary, the appearance is not high, but in ancient times it was very precious. At that time, ordinary people could not afford to eat leeks, because the price was expensive, and even the relatives of the emperor loved to eat leeks, and they also regarded it as a tribute dish of the imperial court.
This is not only because the leek emperor is nutritious and delicious, but also because "Jiu Huang" and "leek yellow" are homophonous, so that it has won the favor of the emperors.
It is said that in ancient times, leeks were not sold on pounds, but on "saving children" for sale, that is, using straw paper cut into one-inch wide and narrow strips of paper to wrap leeks, and the diameter of this leek was a little thicker than that of adult fingers. But at that time, it was necessary to sell for ten yuan a saving, which was very expensive at that time.
The price of leeks in ancient times was expensive, and it had a lot to do with the cultivation technology at that time. Because the previous cultivation of leeks is not as simple as today, the leeks should be planted for two years, and they cannot be cut once during these two years, in order to accumulate enough nutrients in the roots of the leeks.
Cut them off before winter, then dig out the rhizomes and transplant them indoors. After that, it is softened by sand covering and simulates the dark growth environment of leeks. However, the covered sand must be dry, and if there is water leek, it is easy to rot.
The planting cycle is long and the planting cost is high, which is also the reason why the price of leeks in ancient times is expensive.
However, after the 1960s and 1970s, the cultivation method of leeks has made great progress, and the southern region is generally directly covered with bamboo tubes, tile tubes, etc., while the northern regions have low winter temperatures, which are planted indoors in greenhouses.
The cultivation of leeks, at present, is basically to dig the roots of leeks, transplant it and then put a sleeve on it, the current plastic film sleeve is more common.
After passing through the sleeve, the leek grows quickly, and it can generally be cut once in 12-15 days. And leeks and leeks, after cutting can continue to grow, general management of leeks, planting an average of 3 stubble, that is, on average about 15 days to cut once.
After the harvest, the land can continue to start the next batch of production work, and so on. And it is worth mentioning that the regeneration ability of leeks is strong, which is also doomed to its production is not low. Generally, the average yield of leeks per mu of land can reach more than 4,000 jin, and if the purchase price of about 5 yuan a catty is followed, the annual output value of about 20,000 yuan per mu is about 20,000 yuan.
However, at present, there are more leeks, and there are not many farmers who grow leeks, but its demand is very large, especially the leeks around the Spring Festival, which is in short supply, which is also the reason for the high price of leeks.
Conclusion
In fact, the cultivation of leeks is not difficult, but many farmers dare not try it easily. Only because leek also has a disadvantage, that is, it is not tolerant of storage. When it is long enough to harvest season, it must be harvested immediately, otherwise it will be elderly.
And the cut leek is not resistant to storage, must be sold in time, otherwise it will begin to rot after a day, thus affecting its appearance, it is estimated that this is also the reason why many farmers dare not plant leeks.
Friends, do you like to eat leeks? After entering the winter, leeks have begun to be listed, and we should remind everyone that there is a difference between leeks and garlic yellows, which are two different vegetables, of which the appearance is not as long as garlic yellow, and leeks are not as pure yellow as garlic yellow, but yellow is faintly green.
