White shrimp special fertilizer tips

The special organic bio-fertilizers for Penaeus vannamei are jointly developed by Zhejiang Zhefeng Chemical Fertilizer Trace Elements Co., Ltd., Zhejiang University and Zhejiang Academy of Agricultural Sciences. The product is made of high-quality chicken manure, cow dung, rapeseed cake, fish meal and other raw material fermentation processing, can quickly fertilize water quality, adjust the pH of the pool water, improve the water environment, before the release of Penaeus vannamei juvenile shrimp breeding and breeding process And regulate the quality of water quality organic fertilizer. The organic fertilizer is only suitable for freshwater farming.
How to use: (1) Before releasing the seedlings, apply 20-40 kg of water to the shrimp ponds with water depth of 1 meter per acre to fertilize the water body. (2) Normally applying topdressing fertilizer is based on the principle that the transparency of the pool water is maintained at 30-40 cm. The fertilizer amount per mu is about 10 kg per time. (3) The frequency of topdressing depends on the temperature, water quality, and fertility and transparency of shrimp ponds. It is usually applied 5–7 days. (4) The time for topdressing is suitable for sunny mornings. Dissolve in the appropriate amount of water first, then pour it in the shrimp pond and open the aerator at the same time.

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.
