Observing a plant in a row during the cold dew season?

There were five ginkgo trees in front of our school, about the same thickness and height, probably older than my father's age. I love ginkgo trees, especially the ginkgo trees in autumn and the yellow ginkgo leaves in autumn.

Autumn is coming, the green ginkgo biloba leaves begin to turn yellow, especially in the cold dew and frost season, the ginkgo biloba gradually turns from green to yellow, and then from yellow to golden. At this time, the ginkgo biloba decorates the ginkgo tree with a golden color, a high height and a particularly beautiful. The autumn wind is coming, and the ginkgo biloba leaves begin to fall, from the stars to the fluttering, about a month or more.

A piece of golden yellow ginkgo biloba leaves fluttering in the wind, like a beautiful little fan, fanning away the heat of summer, the coolness of autumn, and the cold of winter. The ginkgo tree and the ginkgo biloba are a family, just like a mother and a child, without the permission of the big tree, the leaves will not fall down on their own. I think that the ginkgo biloba leaves that fall down should also have living beings.

This year, they left their mothers in tears, and next year they will surely return to their mother's arms in another way with a cute smile.

Ginkgo biloba also has high medicinal properties. One of the medicines my grandmother took was "Ginkgo Biloba Leaf", which can improve cardiovascular and cerebrovascular circulation and prevent arteriosclerosis. My grandfather also packed a lot of ginkgo biloba leaves and made a ginkgo leaf pillow.

Ginkgo biloba autumn is a landscape, but the falling ginkgo leaves make people feel sour and reluctant.

The cold dew is not considered a cold frost, and the sky has changed. There are many plants still alive in Hanlu. I feel like observing a plant. Didn't look. We are northern. The poplar leaves are all on the ground.

What can be grown in each different period is different, and the suitable things are also different, these are related to the change of weather, so what vegetables can be grown in the cold and dew season? What vegetables are better to grow before and after the cold dew?

1. Cabbage. Native to northern China, it is a leafy vegetable of the Brassica genus in the cruciferous family, usually referring to Chinese cabbage; It also includes bok choy as well as the cultivated variant of cabbage, known as "cabbage" or "cabbage". It is introduced to the south and cultivated in all parts of the north and south.

In the 19th century, it was introduced to Japan, Europe and the United States. Cabbage is eaten with tender leaf balls, rosette leaves or flower stems. The cultivation area and consumption are the first among all types of vegetables in China.

In the planting process, if you want to grow well, you can apply some fertile leaf foliar fertilizer.

2. Spinach. Also known as Persian vegetables, red root vegetables, parrot vegetables, etc., it belongs to the genus Spinach of the Chenopinoa family, an annual herbaceous plant. The plant can be up to 1 m tall, with conical, reddish-tingting, less white, halberd-shaped to ovate, bright green, entire-edged or with a few tooth-like lobes.

There are many types of spinach, which can be divided into two varieties, thorny and thornless, according to the seed form. Spinach is native to Iran and is commonly cultivated in China as one of the most common vegetables.

The mucus protein in yam also has the effect of lowering blood sugar, and mannan can improve glucose metabolism and improve insulin sensitivity, so yam is a good dietary product for diabetics.

Taro is flat and sweet, has the function of regulating and replenishing qi, eliminating carbuncle and dispersing knots, is used for dietary therapy, can treat the lack of middle qi, and can replenish the liver and stomach for a long time, add lean marrow, and enrich the skin.

Elderly people with habitual constipation eat taro and can smooth their stools. The calorie content of taro is not high, and obese people can use it to replace some staple foods of cereals.

The cold dew is close to the Double Ninth Festival, when the chrysanthemum is in full bloom, and the chrysanthemum is the most representative flower in the cold dew season, and its traces can be seen everywhere.

In order to remove autumn dryness, there is drinking in some areas"Chrysanthemum wine"customs. Chrysanthemum wine is made from chrysanthemum with glutinous rice and koji, which is known as in ancient times"Changhuai Xun sue longevity wine"Its taste is cool and sweet, and it has the effects of nourishing the liver, brightening the eyes, strengthening the brain, and delaying aging.

Climbing the mountain and appreciating the chrysanthemums have become the grace of this season. This custom, along with ascending, gradually shifted to the Chung Yeung Festival.
