AI Technical Summary

Problems solved by technology

Since the 1990s, my country's fruit production and area have been ranked first in the world, but fruit and vegetable products have high moisture content and are easy to rot. Inappropriate and insufficient storage and processing capacity, etc., the rot loss rate caused by fruit reaches 30%, and vegetables reach 30%-40%. Fruit rot greatly shortens the shelf supply period and causes economic losses.
