One harm: excessive fertilization will cause imbalance of nutrients in the tree. There is an antagonistic effect between the nutrient segregants, that is, the presence of a certain nutrient segregant can inhibit the activity of another or a plurality of nutrient segregants, thereby affecting the absorption of the tree body. For example, the application of nitrogen fertilizer in acidic soil should not be too much, otherwise it will be difficult for crops to absorb calcium ions. Excessive application of calcium fertilizer can induce crops suffering from zinc, boron, iron, magnesium and manganese deficiency. Excessive potassium use will also affect the absorption of calcium and magnesium ions by fruit trees.
Two harms: excessive fertilization is easy to cause fruit tree poisoning. Due to the application of a large amount of fertilizer, the concentration of the soil solution is increased, so that the roots absorb the water and the inorganic salts, which causes the aboveground parts to wilting. If not remedied in time, the tree will die due to the inability to absorb water.
Three harms: affect the quality of the fruit. In the late stage of fruit growth, if a large amount of nitrogen fertilizer is applied, the sugar content of the fruit will be reduced, the hardness will be lowered, the coloring will be poor, and storage will be imperfect, thereby reducing the commercial value.

LED lamp is a light emitting diode (LED) as the light source of the lamp, with high efficiency, energy saving, environmental protection, long life and so on. LED table lamp uses LED as light source, soft light, no glare, suitable for long-term reading and work. Compared with ordinary desk lamps, LED desk lamps have higher energy efficiency, power consumption is only 20% to 30% of ordinary desk lamps, and the service life is far longer than ordinary desk lamps, up to 50,000 hours under normal use.
The advantages of LED table lamps include high efficiency and energy saving, environmental protection, long life, no strobe, and high color rendering index. It uses blue light isolation technology, which can effectively prevent myopia and protect eye health. In addition, the LED table lamp also has a multi-level dimming function, which can adjust the brightness according to different environments and needs, and improve the comfort of use .
When purchasing LED table lamps, it is recommended to choose products with soft light and high color rendering index according to the use scenario to protect eye health. At the same time, pay attention to the selection of well-known brands and products through national certification to ensure safety and quality. In addition, you can also pay attention to the dimming function, material and design of the lamp to ensure that it is coordinated with the home style and increase the beauty .
