How to make orchids spend the summer safely

Hot summer is a very difficult season for many plants, for orchids, summer has a great impact on its growth, a little carelessness will cause orchid disease, and even death. So if you want the orchid to be able to spend the summer safely, you need to pay attention to several maintenance points that the editor has arranged for you.

Orchid

First, sunshade: the summer sun is shining, and orchids are semi-shaded plants, which can not stand exposure, so orchids must have shading facilities and turn direct light into scattered light. Generally, sunshade net can be used. It is better to set the sunshade net to be active and roll up. Choose the sunshade net (double layer) with a shading rate of 70% to 80%. If you encounter a low temperature on a cloudy day, you can roll up the sunshade net for ventilation, so as to facilitate the growth of bluegrass.

Second, ventilation: high temperature in summer, rolling heat waves on the road, Greenhouse Effect highlights, if orchids do not pay attention to ventilation, it is easy to produce diseases or seedlings. The measures are: first of all, we should pay attention to ventilation to achieve air convection; secondly, we can use electric fan ventilation. Generally use small power, adjustable wind direction of the electric fan or small ceiling fan ventilation, so that the small block ventilation, breeze gently, blue leaves can shake from time to time.

Third, moisturizing: high temperature season, due to large evaporation, orchids easy to scorch head, disease, moisturizing is particularly important. How to create a microclimate for orchid cultivation? according to the experience of orchid friends, we should gradually promote the basic standardization of orchid cultivation, constantly improve the conditions of orchid cultivation, strive to achieve orchid cultivation on flower racks, unify orchid pots, unify plant materials, and unify humidification, so as to achieve the basic norms of management. in this way, the moisturizing effect of orchid cultivation will be better. Specific practice: you can set up a water tray under the flower rack, the height is generally 10mur15cm, and the orchid pot is about 5cm from the water surface. A drainage switch is arranged under the water tray to facilitate the exchange of water. Small aeration pump can also be used to humidify the water. Add anti-disease drugs to the pan water, such as carbendazim, topiramate and so on. In this way, it can not only increase humidity, but also prevent disease, but also play a cooling effect, killing more than one stone. It is appropriate to change the pan water every half a month or so, such as spraying water on the ground, it can basically meet the humidity needs of orchids.

Fourth, disease prevention: high temperature season, disease prevention principle: give priority to prevention, the combination of prevention and control. Should achieve the place of raising orchids, pots, foliar spraying to prevent disease. Carbendazim, topiramate, chlorothalonil and other drugs can be used. In the process of planting: (1) the orchid basin should be clean. Spray and wash commonly used antiviral drugs to prevent germs from breeding on the orchid basin; (2) the place should be disinfected. To the balcony raise orchid place, want to spray medicine regularly to prevent disease; (3) orchid leaf should spray medicine. Especially for one to two weeks of high temperature and humidity, foliar spray should be used in time to prevent disease, drugs should be used in rotation, and bluegrass with disease should be isolated in time to avoid cross-infection.
