With the decline of the outside temperature and the reduction of ventilation, the incidence of downy mildew of cucumber is approaching. Through investigations, vegetable farmers have generally reflected the difficulty in preventing and controlling cucumber downy mildew in recent years. The farmers’ friends had a clearer understanding of the symptoms of downy mildew, and they were able to prescribe the right medicine, but why couldn't they cure it? This is mainly because the condition of the disease is not well understood. To control the occurrence of a certain disease, we must start with controlling the conditions of the disease. The important environmental factors affecting the incidence of cucumber downy mildew are temperature and air humidity, among which air humidity is the most important condition. Here, the point of view to be elaborated is: First of all, we must do a good job of ecological control against downy mildew. Cucumber downy mildew ecological control technologies are: First, to reduce the humidity in the production of greenhouses as the center measures. Water supply under the membrane is used as much as possible to prevent flooding. Flood water is supplied by sunny days and water can not be poured on cloudy and rainy days. Second, strengthen ventilation, temperature and humidity control. At 8 to 13 o'clock in the morning, the greenhouse is heated up, so that the temperature in the greenhouse quickly rises from 10 to 13°C to 25 to 30°C. When the temperature exceeds 33°C, the relative humidity gradually decreases to about 75%. At 13 to 18 o'clock in the afternoon, large slits were opened to reduce the temperature and humidity. The temperature in the shed was maintained at about 25°C, and the relative humidity was lower than 80%. It was not suitable for downy mildew. From 18 to 0, the relative humidity in the shed gradually increased to 80%, and the temperature gradually decreased to 15 to 20°C. The bacteria developed slowly. From 0 midnight to 8 am the next morning, the relative humidity in the shed can reach more than 90%, but due to the temperature dropped to 10 ~ 13 °C, this time is not suitable for infection. In the morning, put 15 minutes of wind first, lower the high air humidity, and put 15 minutes of wind before closing the shed in the afternoon. At this time, the temperature is maintained at about 20°C. Third, high temperature shed. Use sunny weather, seal the greenhouse, raise the temperature at the growing point of the cucumber to 45°C, keep it warm for 2 hours, and then reduce the temperature and increase the temperature, and strengthen the management; or after the first shed, repeat it again every 4 days. 10 to 15 days and then once again, you can also control the development of the disease. However, we must pay attention to the need to maintain as high soil moisture as possible during high temperature sheds. The shed must be watered the next day. The next day, the shed should be effective; the next day, the shed should also be filled with water once, and the temperature must be measured. Observe it once in a minute. Fourth, nutrition prevention. Increase phosphorus and potassium fertilizers to increase plant resistance. After the melons, the bottom leaves were used to reduce the nutrient consumption. After the melon period, 24 to 25 leaves were picked and the vegetative growth was controlled. In the late growth period, the growth is weak, nutrition is insufficient, the nitrogen and sugar content in the plant is decreased, and downy mildew is easily induced; the foliar nitrogen fertilizer can be used to supplement nutrients, and the ratio of nitrogen sugar liquid is 1 part of white sugar and 0.5 part of urea. 100 parts of water were sprayed at intervals of 5 days and sprayed consecutively for 5 times; if downy mildew had already occurred, 58% of toxic manganese zinc or 65% of mancozeb 500 to 600 times of spray could be sprayed in the nitrogen-sugar nutrient solution. It is best to spray at 3 to 4 o'clock in the afternoon to spray on the leaves. The use of chemical control options: Na Nongfu, Anke, decanoyl morpholine, extinction, frost urea manganese zinc, fast deterrence, Jin Lei Duo Mier, Amisida. In addition, while controlling downy mildew, we must pay attention to the simultaneous occurrence of bacterial angular spot.

Franctional Co2 Laser for scar removal(Co2 Laser Machine)




Treatment Principle


This product is due to small size,light weight ,easy to carry,suitable for mobile protable treatment, Co2 laser divergence angel small, good direction,high energy density through focused ,up to several kilowatts per square cemtimeter of power.
