The autumn management of pomegranate trees should be paid attention to, otherwise the tree weakness will directly affect the fruit set rate of the next year.
First, autumn Shi base fertilizer
After harvesting in autumn, the base fertilizer should be applied immediately to restore the tree potential. The base fertilizer is mainly organic fertilizer, and a small amount of new high-fat membrane is mixed to make the fertilizer effect play an early role.
Second, pay attention to winter shears
The pomegranate tree should cultivate three main branches, and the winter is moderately short, so that it extends in the original direction. The main branch and the auxiliary main branch should pay attention to pulling the branch and opening the angle to make it a natural happy shape. Plastic trimming will inevitably cause wounds. If it is not closed in time, it will crack and pollute, creating an environment for the breeding of pests and diseases. Therefore, it is necessary to apply a wounded anti-corrosion film to the wound and promote wound healing.
Third, Qingyuan
After harvesting the fruit, thoroughly clear the garden, and burn the dead branches, fallen leaves, weeds and trimmed branches. Scraping all the decaying winters Before the advent of the cold winter, the protective agent "protecting the tree generals" sprays the upper part of the tree body to prevent disease and reduce freezing damage.
