How to promote orchid blossom
First, light. Illumination is the main factor that promotes budding of orchid plants. The intensity of light varies greatly depending on the type of orchid. When a typical flower bud is forming, if the orchid plant is placed under a bright light, the color of the red, dark red, and yellow will increase. When a green or white flower blooms, the orchid plant should reduce the light intensity as early as possible to ensure that the flower color is more elegant, and then give more light after the flower is finished. Ordinary orchids take 2 to 3 hours of light. The leaves are soft and green, indicating that the light is normal. The leaves are dark green and soft, indicating the need for increased light, and the leaves are yellowish, meaning that the light is reduced.
Second, the temperature. To promote orchid flowering, it is necessary to make the temperature between day and night be about ten degrees Celsius, that is, 18 to 21 degrees Celsius during the day and 7 to 10 degrees Celsius at night, the best growth, more flowering. The high temperature at night will make the orchid plant leaves soft and flower buds fall off. Low temperatures can cause axillary buds and long spots on leaves. During flowering, the plants are exposed to low temperature and brown spots appear on flowers.
Third, watering. How much watering is also the main condition of orchid blossoming, the moisture should be controlled well. More water will make the orchids longer and less probable. The proper moisture is one of the methods to promote opening. However, lack of water, easy to work folder phenomenon will occur.
For the treatment of diseases of the respiratory system:
Diseases and conditions of the respiratory system fall into two categories: Viruses such as influenza, bacterial pneumonia and the new enterovirus respiratory virus that has been diagnosed in children; and chronic diseases, such as asthma and chronic obstructive pulmonary disease (COPD). According to Dr. Neal Chaisson, who practices pulmonary medicine at the Cleveland Clinic, there is not much that can be done for viral infections but to let them run their course. "Antibiotics are not effective in treating viruses and the best thing to do is just rest," he said.
COPD is the intersection of three related conditions - chronic bronchitis, chronic asthma and emphysema, Chaisson told Live Science. It is a progressive disease that makes it increasingly difficult for sufferers to breath.
Asthma is a chronic inflammation of the lung airways that causes coughing, wheezing, chest tightness or shortness of breath, according to Tonya Winders, president of the Allergy & Asthma Network. These signs and symptoms may be worse when a person is exposed to their triggers, which can include air pollution, tobacco smoke, factory fumes, cleaning solvents, infections, pollens, foods, cold air, exercise, chemicals and medications.
Lung cancer is often associated with smoking, but the disease can affect non-smokers as well. Every year, about 16,000 to 24,000 Americans die of lung cancer, even though they have never smoked, according to the American Cancer Society. Like all cancers, lung cancer is caused by the uncontrolled growth of abnormal cells.
