Reasons for the decline of cherry blossoms: 1. Insufficient soil nutrients The flowering of Sakura consumes more water and nutrients, and the nutrients in its site soil will be lost due to various reasons, and the nutrient will be insufficient, resulting in malnutrition of cherry trees and weakening. 2. Soil impervious to trampling and irrational paving cause soil compaction, poor ventilation, poor air permeability, and inhibition of root growth. Most of the cherry trees along the road in the park are subject to human trampling, as well as excavation and filling. The soil compaction causes some of the roots to die, and the tree vigor also weakens. 3. Poor soil texture Piled under the cherry tree, cement, lime, slag, household waste, etc. will deteriorate the physical and chemical properties of the soil. Sloping the sewage, putting the sewage underground passage around the roots of Sakura, etc. will also cause soil contamination. In addition, severe air pollution can also affect the growth of cherry trees. 4. Diseases and Insect Hazards When the cherry tree reaches old age, its ability to resist pests and diseases declines. Once a pest or disease occurs, its tree potential weakens. 5. Mechanical injury and artificial damage Cherry trees on roadsides, scenic areas, and special gardens are often subject to car and other mechanical trauma. Some tourists take pictures on their trunks, break branches, and other acts will affect the healthy growth of cherry blossoms. Based on the analysis of the causes of the debilitating cherry blossoms, identify the dominant factors that cause debilitation. Generally, we must first look at its site conditions to observe and inspect the soil for nutrients, ventilation, air permeability, and whether it is polluted, and whether the leaves, branches, and roots of the cherry tree are damaged (natural and artificial) and polluted. Pests and diseases have occurred and the main causes have been identified. If cherry trees are weakened due to various reasons, effective measures should be taken to remedy the disease and perform comprehensive rejuvenation in a step-by-step manner.
Low-Pressure Auto Parts
This classification mainly includes the aluminum low-pressure casting Machinery Parts using in auto area.
From the part, we can easily find that the parts have a lot of features of big cavities, so the part will have big potential risk of mold release problem, if so, the part may happen to be deform, sticking to the mold etc, especially when the part sticking to the mold, if no clear in time, while next shot, the mold may be destroyed while clamping.
