In recent times, localities are not high temperature or heavy rain. How to manage greenhouse vegetables under this weather condition? 1. Discharge in time to reduce the humidity in the field. After the rainfall, if there is a large amount of water in the field or when rainwater is poured into the shed, the water in the field should be removed or extracted in time to reduce the humidity in the field. The land is conveniently located, using well water to water after the rain, breaking the soil canopy and reducing the impact of rain. 2. Draw the appropriate tillage and break the soil compaction. After the weather turns fine after the rain, proper cultivating according to the soil moisture is beneficial to breaking the soil compaction and enhancing the permeability of the soil. At the same time, the weeding work in the field is completed. For the seedling plot with short colonization time, this operation Particularly important. 3. Strengthen root maintenance and pay attention to the adjustment of plant growth after rain. Open-air vegetables are affected by rainfall, strong winds, etc. Some plants with slings fall off should be slinged in time after rain to restore plant growth. Plants that have been protected from rainwater and irrigated into the shed are timely regulated according to plant growth. When the plant appears to be prolonged after the rain, it should be timely controlled to control the temperature or control the water to control the growth of the plant. The rooting work is the focus of post-rain management. After the rainwater invades the field, the root of the plant is the most influential. For weak plants, rooting can be used or rooted with functional fertilizers to promote the recovery of root growth and absorption. Appropriate spraying of foliar fertilizer is also an important measure to help plant growth, and attention should be paid to spraying. 4. Disease prevention and treatment. After the summer rain, the field humidity is high and the temperature is high. The vegetables in the protected area are prone to disease. It is necessary to reduce the humidity in the shed, enhance the growth of the plant and classify to prevent different diseases, spray the medicinal agent and foliar fertilizer in time, kill the bacteria in time, and do the disease well.

Respiratory disease is a common disease, frequently-occurring disease, the main lesion in the trachea, bronchi, lung and chest, lesions are more cough, chest pain, respiratory effects, severe breathing difficulties, hypoxia, and even respiratory failure and death. Due to air pollution, smoking and other factors, The chronic obstructive pulmonary disease is increasing including chronic bronchitis, emphysema, pulmonary heart disease, bronchial asthma, lung cancer, pulmonary diffuse interstitial fibrosis, and pulmonary infection the morbidity and mortality of the disease at home and abroad . Therefore, anti-respiratory disease drugs are also more and more attention paid by researchers. Respiratory disease have the symptoms of cough, sputum, hemoptysis, chest pain, shortness of breath and other symptoms of lack of specificity, often clinicians mistaken by people for colds, bronchitis, and severe pneumonia, tuberculosis or lung cancer and other diseases delayed diagnosis; Respiratory tract infection, to be developed to emphysema, pulmonary heart disease, respiratory failure was taken seriously, but it was too late, its pathology and physiological function has been difficult to reverse. As with other systemic diseases, careful and detailed medical history and physical examination are the basis for the diagnosis of respiratory diseases, and should be combined with routine laboratory tests and other special findings to conduct a comprehensive and comprehensive analysis. Currently the most clinical application of anti-respiratory disease drugs have the following four categories: 1. Antihistamines 2. Cough medicine 3. Bronchodilator 4. Expectorant 5. Anti-asthma drugs.
