Problems solved by technology

Navel oranges are prone to diseases and insect pests during the planting process. The common ones are mites, scales, leaf miners, and anthracnose, which lead to a decrease in yield. Fruit farmers generally use chemicals to control diseases and insect pests, which not only does not conform to the green, healthy and safe consumption concept of consumers , also pollutes the environment, therefore, the green method of preventing and controlling pests and diseases has broad development prospects

[0003] In addition, during the process of planting navel oranges, there is a common problem of yellowing leaves and fruit drop during the period of rapid expansion of navel oranges. In serious cases, a large number of fruit drop and small hard fruits are produced, and the premature aging of the tree becomes smaller, and the yield and quality decrease.

These are related to insufficient soil fertility and unbalanced nutrients in fertilizers, so that soil nutrients are not suitable for good growth and fruiting of navel orange trees.
