The azaleas of Belgium are the famous potted plants imported from abroad in the 1990s. It has become a leader in gift pots due to its variety, rich colors, colorful colors, warm atmosphere and long flowering period. In recent years, the Belgian azalea has played a major role in the domestic Luhua Market and has gradually entered the families of the people with high quality, low cost, and large quantity. Biological characteristics Belgian Rhododendron requires about 12 hours of light every day, avoid direct light, with 60% intensity of natural light is appropriate. The optimum temperature for survival is 0°C-35°C, and the appropriate temperature for breeding is 15°C-25°C. Cultivation substrates require loose, breathable, permeable water. The pH requirement is 5-6. The cultivation medium should be kept moist for long periods of time. Not intolerant to concentrated fertilizer, it requires thin and hard-working facilities. The flowering control technology is timely shaping, and the plasticity time is determined based on the artificially set flowering period and the gestation time required to regulate the variety. The main methods are: short cuts for strong new shoots; playing tips for general new shoots; combining the design to remove the sick and broken branches. About 20-30 days after the application of the growth inhibitor, the plant growth inhibitor can be sprayed when the shoot length reaches about 3 cm, and the plant can be transformed from vegetative growth to reproductive growth, so that the flower bud differentiation is punctual and well-developed. After adjusting the proportion of nutrient components, flower bud differentiation, plant growth is dominated by reproductive growth, and phosphorus and potassium fertilizers are the main nutrient components. The ratio of nitrogen, phosphorus, and potassium in the incubation period is preferably 15:18:18. The use of temperature-control facilities to adjust the flowering period error due to unforeseen environmental impacts, there is inevitably a certain amount of error in flowering control. The adjustment method is to appropriately increase or decrease the temperature to speed up or delay the opening of the flower bud. The suitable temperature for flowering buds is 25°C during the day and 15°C during the night. Most of the Belgian azaleas that circulate in soil-less potted plants use earthless potted plants. The essentials of soilless cultivation lie in the selection of cultivation substrates. The more economical and practical cultivation substrates are: coco peat, peat, expanded perlite, carbonized rice hulls, and cedar shavings. Commonly used ratio (volume ratio): (1) coconut cocoon 1: peat 1; (2) coco cocoon 1: peat 2; perlite 0.3; (3) fir chips 1: peat 2; (4) carbonized rice husk 1 : Peat 1.5; (5) Perlite 1: Peat 3. Common Diseases and Pest Control The physiological lesions in the common diseases of Rhododendron in Belgium are mainly caused by differences in the quality of water between production and sales areas, and in the absence of adequate air temperature during transportation or when the home is indoors. The method of treatment is mainly based on the physiological habits of Belgian rhododendrons with good lighting, pH and temperature of irrigation water. The common diseases that belong to the pathology are: The basic measures for the treatment of gray mold, such as thinning seedlings, lowering humidity, and keeping warm. Drug treatment may be selected from the group consisting of fluocin (1500-fold solution), mancozeb (500-fold solution), quick-acting (150-fold solution), and chlorothalonil (600-fold solution) fungicides. Generally used 2-3 times, interval 7-10 days once, rotation is better. Whitefly, a whitefly, generally harms the roots. The cultivation matrix should be strictly selected and precautions such as exposure or mixing should be used before use. Medications can be treated with Enkeson (500x solution) or Pentachloronitrobenzene (800x solution) during rooting. The general application can be eliminated twice, with an interval of about 10 days. Stalk rot stalk rot usually occurs on seedbeds and the symptoms are the rot of the base of the seedlings. Transplanting seedlings in time is the fundamental method of governance. Drug control with anti-virus (600 times liquid) or Dubok Kelu (600 times liquid) to root, the effect is better. The common insect pests are mainly aphids and red spiders, which are sprayed with aphid (1,500 times liquid) or avermectin (3000 times liquid) for drug control. The general spray can be solved 2 times, once in 7-10 days. China Agricultural Network Editor
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.
