This year's Huaihua blooms warmly, just because the temperature is high and more rainwater

A rain sent a hint of coolness to the hot Taiyuan, and the locust flowers that opened the branches filled the ground. In hot weather, such scenes make people feel refreshing and comfortable. It is said that "May locust flowers", but this year, August is more than half, but the branches of locust trees are still flowers. Why? The Huaihua is so prosperous, but why can't you smell the strong incense of Huaihua? Xie Xinggang, Chief of the Tree Research Office of Taiyuan Garden Science and Technology Innovation Service Center, answered.

The branches of the Chinese locust are enthusiastically on the locust.

Chinese locust blooms in summer

"May Huaihua incense", many people think that Huaihua is opened in May, but why is it in July and August this year, and Huaihua is still so enthusiastic? This will start with the type of locust tree.

There are many family members of locust trees. Common ones are Chinese locust, dragon claw locusts, locust, fragrant locust, and Mao Yanghuai.

Dragon claw locust, wins in the shape, like the flying dragon circling in the air, the small branches are like a willow, and the branches are like a strong man in the north. From July to August, the fruiting period is August to October.

The name of the locust is due to the thorn thorn on the branches. The locust was native to North America and was introduced into China at the end of the 18th century, so it was called Hu locusto. In the early spring and summer of late spring and summer, a string of locust flowers, hanging in the green leaves, white as white as snow, simple and bright, in the air of the countryside, there is a faint fragrance, refreshing. Flower period from April to June, fruiting period from August to September. "May locust flower fragrance" is said to be locusting. The fragrance is strong and the fragrance is full of fragrance.

Fragrant locust is a cultivated variant of locusting, belongs to the trees. Mao Yanghuai belongs to shrubs. Fragrant locust and Mao Yanghuai flowers are rose red. From May to July, the flowering period is long. "Recently, the flowers we saw on the streets of Taiyuan City were opened. It was called Guohuai, and it was also the city tree in Taiyuan. Its flowering period was in summer, June -August." Xie Xinggang introduced. Guohuai is unique to Huaxia in the name of the country. Chinese locust is native to China, also known as China Huai. It is mainly distributed in northern China, Northwest, Northeast my country and other regions. It can grow in the plains and the Loess Plateau at an altitude of 1000 meters. It can even live well in places with few water in mountainous areas. "The tree can be the shade, non -locust is the elm." In the north, Yangliu Yuhuai can be said to be the most common indigenous trees. The Chinese locusts of the butterfly -shaped flower family belong to the leaves and trees. The national locust -like compound leaves, oblong, dark green, gradually pointed at the top. When germination in spring, the round and small tender green leaves are extremely eye -catching on the dark branches. In summer, the locust flowers are covered with branches, and the trees fall are colorful, sending refreshing to the fiery summer. In the midsummer where the fragrance was gradually less, the Chinese locust opened the yellow and white bouquet, which was complicated and fine, but it was not imposing.

Although it has been autumn, the locust tree is still colorful.

High temperature and precipitation, promote the opening of locust flowers

Yellow and white flowers, clusters of clusters, pieces, hanging between dense green leaves, different styles. Especially after the rain, the green leaves of the Chinese locust are brighter, and a bunch of light yellow flowers are hidden in the dark green leaves and shake the heart.

In fact, the flowering period of Guohuai is very long, seven or eighty days, from June to August, and the fruiting period is from October to November. "However, this year's Chinese locust has obviously more flowers than in previous years." Xie Xinggang introduced that as a city tree in Taiyuan, Guohuai has been planted in the streets, parks, and communities in Taiyuan City. At present, the Chinese locust in Taiyuan is mostly 30 to 60 years old. The age of this tree is in the adolescents of Guohuai, so it is easy to bloom and spend a large amount.

However, how much Chinese Huai blossoms is closely related to the climate of the year.

The Chinese locust in Taiyuan City generally germinate new leaves in mid -to -late April. The flowering amount of Chinese locust is closely related to its flower bud differentiation. Since entering the summer this year, the temperature in May and June is higher than usual, especially the continuous high temperature weather in late June, which has made Taiyuan earlier. Higher temperature suppress the nutritional growth of Chinese locust, but significantly promotes the differentiation and growth of Chinese locust flower buds.

It is important that there are more precipitation from late June to early July this year, providing sufficient water for the blooming of Chinese locust. Appropriate temperature, sufficient water and other climate conditions have greatly promoted the flowering of Chinese locust.

Various conditions make the Chinese locust bloom this summer, adding a different color to this hot summer. "Of course, the flowers of Chinese locust biography have the law of 'big and small years'. Last year, Guohuai's flowers opened less, which increased significantly this year's flowering volume. It is expected that the number of flowers in Guohuai will decrease next year." Xie Xinggang introduced.

Chinese locust flower has toxins, which can be used for medicine after treatment

Perhaps in the childhood memory of many people, the season of locust blossoms is also the happiest time for children. Standing on the tree, put a bunch of locust flowers into your mouth, full of fragrance. The hard -working mother will make the Huaihua make a variety of foods, so that the whole family will be full. Today, although it has been autumn, the locust blossoms are still blooming. Although the fragrance is not so strong, it still attracts the index finger.

Can Guohuai Huaihua eat it? "Everyone must note that the flowers of Chinese locust cannot be eaten, and the flowers of locusting can be eaten." Xie Xinggang introduced that whether it is Chinese locust or locust, it is commonly known as "locust tree" in life. "So many people confuse the two. In fact, the flowers of Chinese locust have toxins and can not be eaten, but they can be used as medicine after being used to be poisoned. The spiny locust flower is non -toxic, can be eaten, and the taste is sweet and sweet, rich in vitamins and various minerals.

Huaihua's blooming is intoxicating, but people who are allergic to pollen are very distressed.Xie Xinggang said that the pollen of Guohuai may really cause allergic reactions, but the degree of allergies is different based on personal conditions. Therefore, people who are easy to be sensitive to Guohuai pollen must take corresponding protection measures.Reporter Yang Xiaoyanwen/Photo
