Amaranth is a common vegetable variety in our life. Amaranth stuffing dumplings are believed to be eaten by many friends. Amaranth is very common in rural fields. It can be sold not only at home but also at home. And the leek can be planted in spring, summer and autumn, with good benefits. If you grow amaranth in the fall, it is usually planted before and after the fall, which is the latest. The following small series will tell you about the precautions for planting amaranth in the fall. Let's learn together.
1. The amount of seeding before and after the autumn is twice as large as that of spring.
Because the weather becomes colder after the autumn, although the amaranth has a high cold tolerance, it will grow slowly and the root growth will be slow when it is in a low temperature environment for a long time. The less the root system, the easier it is to freeze to death in winter, so increasing the amount of seeding can increase the root amount of amaranth and reduce the chance of freezing roots in winter.
2, prevention of grass damage
After the autumn, the air temperature and humidity are very suitable for the growth of weeds. The growth of weeds can easily affect the growth of amaranth. Therefore, after planting amaranth, weeds should be removed in time to prevent excessive weeds from affecting the growth of amaranth.
In spring sowing, summer sowing and autumn sowing, it is best to plant leeks in spring. In the spring of March, when the ground temperature is between 5-10 degrees, the surface is relatively moist, sowing the leeks is easy to germinate. At this time, the weeds have not grown, so the leeks can grow up before the weeds grow. Effectively avoid grass damage. So I suggest that everyone plant as much as possible in the spring.
The above is the precautions about the cultivation of leeks in the fall of Hui Nong. Recently, the price of vegetables has risen. Whether it is for sale or for eating by yourself, it is a good choice to plant some leeks in the ground.

Clinical PW A detection
Port wine stains ( PWS ) is always a birthmark . It is caused by a vascular anomaly. PA imaging could provide real-time information about the thickness of the skin and diameter. depth, distribution of blood vessel , which provide significant help with clinical diagnosis and treatment.
PAI VS. OCT

OCT 0.4 mm
Functional identification : With optical fingerprint characteristics ,P A could specificity imaging blood vessels , eliminates the interference of hair follicle, sebaceous glands.
The clinical testing has been carried out in 301 and guangzhou military general hospital , testing and statistic all kinds of PWS lesions in patients with vasculal parameters , in order to establish the classification and quantitative treatment of PWS.
