Pre-winter fertilization should be dominated by farmyard fertilizers and compound fertilizers, with no or less nitrogen fertilizer applied. If the nitrogen fertilizer is applied excessively, the seedling branches will be prosperous, the degree of lignification will be low, and the cold resistance will be reduced. Fertilizer should be applied to the lateral roots of seedlings.
Tree trunk white: catch the sunny weather with lime plus lime sulfur on the branches of white, can reduce the seedling sunny side due to the large temperature difference between day and night and the damage, but also can kill the winter of bacteria and eggs, in one fell swoop Got it.
Main trunk "clothing": For seedlings that are not tolerant to cold, use a straw rope to wrap dry or wrap straw and some of the main branches with straw so that the seedlings wear "cotton" before winter to prevent freezing.
Scrape the skin and apply medicine: In the early winter, remove the diseased skin and worm skin from the trunk, branch and branch branches of the seedlings, and burn them centrally or deeply to destroy the pathogenic bacteria and eggs that overwinter in the bark. Depth of skin scraping is preferably yellowish-green on the skin. Apply 40% of Formamide WP to 50-100 times or 5 to 10 Baume Degree Lithosulfide to protect wounds.
Set the impediment to the wind: In order to resist and reduce the cold and dry gale may cause damage to the nursery stock, erect the windbreak wall in the upper direction of the nursery before winter. The height of the windbreak exceeds the height of the tree. In addition, the wind wall should be fixed with wooden sticks, bamboo poles, etc. to prevent it from being blown by strong winds.
Water control and antifreeze: After entering the winter, strict control of water is required. In addition to being particularly arid, water irrigation is generally not required. Because if the water content of the tree is too large, once the low temperature is encountered, the tree will swell and swell, causing cracking of the bark and death of the seedlings.
Spraying and Killing: After seedlings defoliation, 5 Baume Mildioliths plus 200 times sodium pentachlorophenol are sprayed to eliminate overwintering germs and eggs.
When human beings have experienced disasters, we know that life and health are so precious.

• 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,
