Strawberries: Europe's "queen Of Fruits"

Besides "the first cup of milk tea in the fall", did you reach the "first strawberry in winter"? If you can't catch up, don't miss this wave in winter / spring.

You may not know that the strawberries you are eating right now are actually summer fruits. Shui Lingling, bright red, like a small strawberry lantern, bite, soft and juicy, sweet and sour, with a strong fruity aroma, has a reputation in Europe as "the Queen of Fruits". In fact, strawberries love a warm and cool climate, and the optimal temperature is 15-25 degrees Celsius. The "Queen of Fruit" is also very delicate: neither too hot nor too cold, too low or too high temperature does not hinder its development, and if it drops below minus 8 degrees, it makes it "sweet". Therefore, the strawberry harvest season should fall at the end of spring and the beginning of summer.

Strawberries are rich in vitamin C, fiber, potassium, salicylic acid, tannins and other organic acids and flavonoids, have a good antioxidant effect, protect skin and hair, and aid weight loss. Dietary fiber and tannin acid contained in strawberries prevent the absorption of carcinogens. Traditional Chinese medicine believes that strawberries have a sweet and cool character, moisturize the lungs and increase body fluids, rejuvenate the spleen and stomach, have diuretic and anti-swelling properties, suppress heat and carry away summer heat.

That's right, your favorite strawberry is actually an imported variety. It is one of the largest fruity pineapple strawberries. It was introduced in the early 1900s, but has only over 100 years of history. In the decades after strawberry cultivation, it was essentially a holistic method of growing outdoors and little attention was paid to commercialization. Back then, strawberries were just a luxury, it was difficult to eat strawberries in summer, let alone strawberries in winter. When you enter the fruit store this winter, the strawberries will not fade away and will be displayed in a prominent place. Strawberry cakes, strawberry croissants, strawberry drinks and many other "blueberry" products rank first in the dessert shop.

So how did strawberries, originally summer fruit, become available all year round and even become a "winter limitation"? In fact, it's all thanks to greenhouse technology. Modern greenhouse technology requires little or no artificial heating or even artificial conditions to provide a cold-resistant and heat-retaining environment for temperature-loving plants during the normal growing season. And Shiwen strawberries are one of the lucky ones to "stay inside".

Having found a suitable home for strawberries, it is cold, you need to put on a "winter coat": to achieve the ideal growth temperature of strawberries, it will sometimes be like a nesting doll, a greenhouse. covered with the middle barn, the middle barn is covered with a small barn and an additional layer is added.Mulch, tightly wrap the strawberry seedlings. This is not putting strawberry seedlings in a greenhouse and making a plastic foil bag. Strawberries grown in greenhouses usually require strong disease resistant, low temperature and good cold resistant varieties such as plain Japanese red surface, American sweet Charlie and others. If the wrong variety is chosen and the temperature is not well controlled, tender strawberry seedlings may only end up with the pearl sinking and the jade bursting.

The Fruit Princess is not only delicate when growing, but also untouchable when picked. Therefore, strawberry packaging is now used to cover fruit with foam sleeves or to use boxes with holes to separate strawberries for cushioning and buffering, all to reduce damage from external forces during transport. In addition, refrigerators, canned chemicals, air-conditioned refrigerated trucks, etc. can be used to keep it fresh. There are eighteen types of martial arts. Just to have fresh strawberries in front of you.

Or are you worried if the big sweet strawberries will get sprayed with pesticides? In fact, you can be sure that the strawberries grown in the greenhouse during the off-season are safe and hygienic. Improvements in seedling technology have made strawberry seedlings "soft and pendulous, thin and timid and out of control". You can also "see, hear and ask" during the selection process. The appearance is fresh and intact, no peculiar smell, no insect damage. And the redder the strawberry, the more it matures.

If you are still not in the mood, you can wash the strawberries you buy. Rinse with clean water to remove surface contamination, then add baking soda to defrost it. Baking soda solution removes pesticide residues to some extent. After careful care
