Hello, Plaese I need help to know the reason was Adobe Stock rejected my pic.


Too blurry, probably because the camera was too close to your subject.
Next time use a tripod and check your depth-of-field.

Also, Stock's database contains 21+ million flowers. This will be a tough sell due to fierce competition from other contributors in this category.
Choosing profitable subjects to shoot is probably the biggest challenge for new Stock Photographers.
