The reasons for the weak growth of cherry blossoms
1. Insufficient soil nutrition cherry blossom consumes more water and nutrients, and its site soil nutrients will be lost due to a variety of reasons, lack of nutrients, resulting in malnutrition and weakness of cherry trees.
two。 Soil impermeability trampling and unreasonable paving and other man-made causes of soil consolidation, poor ventilation, poor air permeability, inhibit the growth of roots.
Most of the cherry trees along the road in the park are affected by man-made trampling, excavation, filling and so on. Soil consolidation causes part of the root system to die, and the tree potential is also weak.
3. The poor soil texture will worsen the physical and chemical properties of the soil by stacking cement, lime, slag and domestic waste under the cherry trees. Disorderly dumping of sewage and setting the underground passage of sewage around the cherry root system will also lead to soil pollution. In addition, serious air pollution will also affect the growth of cherry trees.
4. Diseases and insect pests harm cherry trees into old age, the ability to resist diseases and insect pests is weakened, once the occurrence of diseases and insect pests, the tree potential will also be weakened.
5. Mechanical injuries and man-made injuries to cherry trees along roadsides, scenic spots and special gardens will often suffer from car and other mechanical injuries, and some visitors' behaviors such as carving names on tree trunks and breaking branches will affect the healthy growth of cherry blossoms.
According to the analysis of the causes of the weakness of cherry blossoms, the main factors causing the weakness were found out. Generally, we first look at the site conditions, observe and test the nutrients, ventilation, air permeability and pollution of the soil, and then see whether the leaves, branches and roots of cherry trees are damaged (both natural and man-made) and polluted. whether there are diseases and insect pests, find out the main causes. If the cherry trees are weak due to a variety of reasons, effective measures should be taken to prescribe the right medicine and carry out comprehensive rejuvenation step by step.
