Potato premature aging refers to a series of "false ripening" phenomena that appear to be mature on the surface, such as falling leaves and dying before the harvest season, but actually do not reach natural physiological maturity. The occurrence of premature aging will seriously affect the later production.
Causes of premature aging
Climate reasons. When the temperature is too low in early spring and winter, and the sunlight is too strong, it will cause the potato to age prematurely and affect its growth.
Causes of phytotoxicity. Spraying high-concentration regulators, etc., will have hidden premature aging. If farmers do not find it, they will miss the opportunity.
Strengthen management
Remove old leaves. Timely removal of old leaves, dead leaves and diseased leaves can not only reduce nutrient consumption, but also effectively control the spread and spread of diseases.
Pay attention to moisture. If the soil is too dry in the middle and late stages, add water in time. If the soil is too wet, it should be drained in time to avoid excessive leaf surface consumption of nutrients, or aggravation of disease.

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
Image depth : PA 2 mm
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.
