After a severe storm, the honeysuckle plants tilted to varying degrees, or even fell down, with broken branches and fallen leaves all over the place. The leaves and flower buds on the tree were also injured more seriously. These injuries reduce the assimilation of the plants and weaken the tree vigor, and it is difficult to restore the tree vigor to the seriously damaged plants within 2-3 years.
Heavy rainfall can cause water accumulation and rooting in the orchard, causing root rot and even dead trees. At the same time, high air humidity after continuous heavy rainfall, coupled with the high temperature in the June and July flood seasons, will cause various diseases. In order to minimize the loss of honeysuckle production, the following aspects of management must be done after a severe storm:
Waterlogging: Drainage ditches should be dug in time to restore soil aeration and prevent suffocation of roots that can cause fallen leaves and buds and weaken tree vigor.
Centering: The fallen and sloping trees must be centered and fixed within 3 days. It should be lifted slowly when straightening. It is not possible to break the big roots to make the tree stand upright. It is best to use three wooden poles to support the triangle to prevent the wind from falling down when the root system is not fully restored.
Pruning: For drooping branches that are broken but not lost, they should be immediately placed at the appropriate branch (preferably cut at the split). The splits of the broken branches should also be cut at appropriate branches to make the cut smooth and facilitate healing. The rainy season is full of moisture, so we should pay special attention to summer shears for honeysuckle, and we must cut every branch, mainly sparse. Residual branches and leaves should be cleared out of the orchard in time to reduce the source of diseases and insects.
Fertilization: Fertilization should be based on nitrogen and phosphate fertilizers to promote vegetative growth. Apply 15-20 kg of compound fertilizer per mu, spread a shallow trench and spread it on the soil next to the plant, or spray 300 times potassium dihydrogen phosphate and 200 times urea solution.
Defloration: Pick flowers in time, take full advantage of the opportunity after the rain and pick the branches and buds in time, increase income as much as possible, and reduce losses.
Disease prevention: After severe storms and rains, the wounds have high humidity and bacteria can easily invade. Therefore, when it is sunny, spray insecticides immediately.
