Problems solved by technology

The common problems in the navel orange planting process are that the navel oranges have different degrees of leaf yellowing and fruit drop during the period of rapid fruit expansion. The leaves lose green and yellow, resulting in a large number of fruit drop and small hard fruit. Reduced, less pulp juice, too sour taste, difficult to drink, etc.

These problems are mainly due to insufficient soil fertility or too random fertilization, uncoordinated fertilizer nutrient ratio, and poor fertilizer efficiency, resulting in soil nutrients that are not suitable for the good growth results of navel orange trees.
