First, choose a good seedlings. Choose high-quality seedlings that are free of pests and diseases, have robust growth, have a well-developed root system, and have short internodes and no dehydration. Second, the root treatment. Cut rot roots, dried and dehydrated roots, and roots before planting. Rotten root cut to bare white so far. Even a good part of the roots needs to be cut off slightly, and its main role is to control the root-causing bacteria and stimulate the sprouting of new roots. Third, digging pit seedlings. Year ago, dig a planting pit or ditch. Apply enough organic manure to fill in the soil and then water it. When planting, raise the seedlings while filling the soil so that the root system is in full contact with the soil to prevent seedlings from hanging. The earth around the trunk should be solid and down-studded, and the seedlings of the middle anvil should be dwarfed. Fourth, timely watering. After the seedlings are planted, they should be immediately irrigated with water to ensure the water supply to the seedlings. Fifth, science will be dry. After the seedlings are planted, they are usually cut short at full shoots of 60-70 cm depending on the height of the seedlings, and then painted with bio-oil or paint to prevent draining. Six, weeding weeding. Weeding and weeding of the seedlings in time will play a role in loosening the soil, raising the temperature, and maintaining the sensation. Seven, catch fertilizer late. After the seedlings are resuscitated, the roots have just been active. At this time, topdressing chemical fertilizers will easily burn the roots and cause dead seedlings. Chemical fertilizers should be chased later.

When human beings have experienced disasters, we know that life and health are so precious.

When the blue sky becomes gray, we realize that fresh air is so precious. Oxygen is the guarantee
of human survival.
• Benefits of Oxygen:
Inhalation of oxygen can improve the level of arterial blood oxygen partial pressure and oxygen
saturation of the body, in addition to promote the metabolism of the body, and is also one of the very
important methods for auxiliary treatment of a variety of diseases. Oxygen inhalation can make the
oxygen in the human tissue more abundant, cells will get sufficient oxygen supply after the
metabolism will be more active, normal people will have a refreshed, memory improved, spirit feeling.
Patients with chronic heart and lung diseases, long-term oxygen inhalation can delay the aggravation
of the disease, at the same time, but also can relieve the symptoms of chest tightness, wheezing and
dyspnea of patients. Especially when working under great pressure, they are prone to dizziness,

dizziness and restlessness.
