Orchid planting and cultivation: the cultivation and Management of Orchid in August

In August, we must pay attention to the management of orchids, actively deal with autumn tigers, and prevent heat and cool down. although there are two seasons of the Beginning of Autumn and the End of Heat in August, the monthly average temperature is similar to that of July, and the weather is extremely hot, which is the second high temperature month of the year. For orchid farmers: the Beginning of Autumn must not be careless in season and should actively deal with autumn tigers. Once the temperature in the orchid room exceeds 30 ℃, ventilation should be strengthened to cool down. Timely watering to avoid dryness of diamond shells. In the golden autumn, the sky is high and cloudy, the sun is bright, and the water evaporation is large. The basin soil is easy to dry from the bottom of the basin, forming rhombus dryness, affecting the development of flower buds and endangering the root of orchid. A variety of measures can be taken, such as water curtain humidification, water basin humidification, ground water spraying, humidifier humidification and so on, to create a dry air relative humidity of 40% during the day. In addition, people who raise orchids need to be diligent in observing the dry and wet condition of the basin soil. if they find that the basin soil is too dry, they should pour water at the right time to keep the soil moist and not stained, and avoid being too dry.

Proceed from the reality, let the orchid receive more light. After the middle of August, the degree of shade should be reduced as much as possible according to the environment of orchid culture. Except for proper shade in courtyard and roof platform, orchids can receive sufficient light in other places, especially in the whole pot. In the evening, the orchid room sliding window should be opened as far as possible, so that bluegrass can be fully ventilated to maximize the temperature difference between day and night.

Fertilization promotes health and buds. In the middle and last ten days of this month, the strong seedlings of bluegrass should be fertilized in time, and the root application of organic fertilizer and foliar spraying fertilizer can be carried out alternately. This month, bluegrass begins to give birth to buds, commonly known as Xiaopailing, to properly increase the application of phosphorus and potassium fertilizer, in order to promote strong buds and ensure the growth of autumn buds, and lay a good foundation for the breeding of strong buds in early spring next year. Fertilizer application should be carried out in the evening. In order to prevent fertilizer damage, it should be watered in time the next morning.

Actively deal with extreme weather and control diseases and insect pests. There are many rainy and rainy weather in many areas this month, and outdoor orchid cultivation should strengthen orchid rooms. This month, diseases and insect pests are rampant in the overcast and humid climate, and there is a high incidence of soft rot, stem rot, and other diseases and insect pests. We should continue to do a good job in the prevention and control of diseases and insect pests. Spraying medicine should be carried out in the evening on a sunny day, not only to spray orchid leaves, orchid pots, but also to spray the whole orchid shed, so that the fruit is better.
