After entering the rainy season, hot and humid weather will provide favorable conditions for the occurrence and spread of fruit tree diseases and insect pests. Therefore, the majority of fruit farmers should strengthen orchard management. details as follows:
1. Clear the ditch in time to drain water.
Fruit farmers should listen to the weather forecast and clean up the drainage ditch in time so that the rainwater is discharged in time. Always maintain a certain degree of humidity and air permeability in the soil to prevent problems such as cracking of the soil caused by rapid changes in drought and flood. Orchards with difficulty in natural drainage should implement forced drainage by pumps in advance to avoid orchards suffering from hypoxia in soil due to excessive water accumulation and post-disaster high temperatures, and plant root death.
2. Clean up the orchard in time.
The heavy rain is often accompanied by wind. The orchard should be cleaned in time after the rain, mainly to remove broken branches, fallen leaves, fallen fruits, and rotten fruits, and concentrated treatment to reduce the source of infection. Pruning the branches of the fruit tree, immediately correcting the deviated and fallen tree body, and properly removing some leaves and fruits of the fruit tree with severe root injury to reduce transpiration and reduce the load.
3. Prevent diseases and insect pests in time.
Due to the erosion of heavy rain, the leaves are damaged to varying degrees, and the high temperature and high humidity environment is likely to cause disease outbreaks. Therefore, comprehensive control of diseases and insect pests must be strengthened. Focus on the prevention and treatment of grape downy mildew, white rot, anthracnose; peach brown rot, anthracnose, bacterial perforation, peach worm; pear black spot disease, pear worm, and other fruit tree diseases and insect pests. In addition, each orchard can be top-dressed with compound fertilizer after rain to enhance tree vigor according to the actual production. For orchards that have not been bagged, they should be bagged in time after replenishment.
