When do rapeseed flowers bloom? What are their benefits and effects?
Rapeseed flowers are cool in nature and sweet in taste, and have the benefits of invigorating blood and resolving stasis, and of detoxifying and reducing swelling. So when do rapeseed flowers bloom? What benefits and effects do rapeseed flowers have? Let's find out together.
1. When do rapeseed flowers bloom?
1. Flowering period
It begins to bloom around March and April each year. But in some places it is earlier, and in others a little later. In different years, the blooming time also differs. Generally, rapeseed flowers begin to bloom about three months after planting. Their flowering period lasts about thirty days. There are also many factors that affect how early or late they bloom.
The first is the temperature factor. The faster the temperature rises, the earlier the blooming time will be. Under normal circumstances, they begin to bloom as early as the end of February, bloom most vigorously in mid-March, and wither around the end of March to before Qingming. But if there is sustained low temperature in spring, then rapeseed flowers may not bloom until mid-March.
2. Blooming times in different regions
(1) Latitude and longitude factors
Rapeseed flowers are distributed extremely widely in our country, so according to differences in the planting region, and differences in latitude and land-sea position, rapeseed flowers are divided into two major regions: spring rapeseed and winter rapeseed. Therefore, in terms of blooming time, generally from the end of December each year all the way to the end of April of the following year, rapeseed flowers can be seen in different places.
In southern Taiwan, China, blooming rapeseed flowers can be enjoyed as early as the end of December, and in a warm winter the flowering period comes even earlier. From January to February, rapeseed flowers mainly bloom in Yunnan, Guangdong, Guangxi and other regions, and in March and April the Sichuan Basin and areas north of the Wuyi Mountains enter the flowering period.
(2) Vertical altitude factors
Altitude also has varying degrees of influence on their blooming. This factor is especially obvious in the western regions of our country; flowers bloom all over the river valley areas, entering the flowering period every July and August. However, because of the existence of the Qinghai-Tibet Plateau, the situation has changed somewhat. What should have been cold in the north and warm in the south has become hot in the north and cold in the south, so the phenomenon appears that the Junggar Basin blooms in June, while Tibet and Qinghai do not bloom until July and August.
2. The benefits and effects of rapeseed flowers
1. Rapeseed pollen has the effect of comprehensively supplementing nutrition: rapeseed flower pollen is not only the source of life for the plant; it can be said that rapeseed pollen is a “miniature nutritional treasure house.” Expert experimental data show that the protein content of every hundred grams of pollen can reach as high as 25-30 grams, including more than a dozen amino acids, and in a free state, extremely easy for the human body to absorb.
2. Rapeseed pollen has the effect of delaying aging: rapeseed pollen not only contains nutrients, but also contains nucleic acids and certain hormones, auxins, antibiotics and so on that delay human aging. Taking pollen can effectively delay aging.
3. Rapeseed pollen has the effect of caring for and beautifying the skin: rapeseed flower pollen is a nutritional beauty cosmetic. Components in the pollen such as VE, superoxide dismutase (SOD) and selenium can moisturize and nourish the skin, and restore the skin's elasticity and smoothness.
4. Rapeseed pollen has the effect of protecting the prostate: experiments show that rapeseed pollen has a significant effect on chronic prostatitis, and can prevent prostate enlargement and prostate dysfunction.
