Detailed Explanation of Key Techniques for Summer Management of Citrus Orchards
From the perspective of the phenological stages of citrus growth and development, summer occurs during the young fruit stage (second physiological fruit drop period) through the summer shoot emergence period. Citrus fruits enter the expansion stage, requiring larger amounts of fertilizer and water. This coincides with the hot and humid season, which is also the peak period for citrus pests and diseases.

Key Points of Summer Citrus Pest and Disease Control Techniques
Summer's high temperature and high humidity make it the season with the highest incidence of citrus pests and diseases in the entire year. If pest and disease control is inadequate during this period, it will seriously affect the cultivation of young citrus branches and shoots, affect the development of young fruit on bearing trees, and even trigger massive fruit drop. Therefore, it is essential to effectively strengthen summer

Detailed Explanation of Key Techniques for Autumn Management of Apple Trees
The peak period of flower bud differentiation in apple trees occurs in autumn. Doing a good job of autumn management of apple trees can lay a solid foundation for high, stable and high-quality yields in the following year. Fertilizer and water management For non-bearing trees, 0.15-0.25 kg of diammonium phosphate can be applied per tree; for large bearing trees, according to the planned yield for the following year, 0.7 kg of pure nitrogen and 0.7 kg of available phosphorus can be applied per 100 kg of fruit. Topdressing for young trees can significantly increase the sprouting rate in the following year. For large trees in full bearing period, applying fertilizer in autumn year after year, under the same amount and types of fertilizer, compared with topdressing in early summer, can increase the yield by about 50 kg per tree.
