How to make orchids survive the winter in the open air

With the development of orchid industry, many orchids are planted in Ailan, and there are many orchids in the open air all over the country, but some growers, especially in remote rural areas, are restricted by economic conditions, so they can only use soil methods to build sheds (shelves) to shade orchids. According to the planting area, the shade shed (frame) shade net equation is different. It is best to choose a vertical column to build a shed (frame) with a cross pole, and it is most appropriate to cover the surface of the scaffolding with branches and brooms. Cover the broom according to the percentage of sunlight needed. Although this method takes more materials and more man-hours, it can be changed every 5 to 6 years. The advantage of this scaffolding is that the cover of a branch broom insulates the orchid from direct contact with the air. Despite the frosty weather, no matter how big the frost is, the orchid leaves will not be affected by frost. Do not use the shed (shelf) if you encounter Daming frost, the frost period is as long as more than a month, it will smack the orchid leaves and smack the whole nest to death. In the snow freezing season in nine cold days, orchids are both beaten by frost and frozen by snow. In that case, the damage to orchids is even greater. The orchid leaves withered and shrunk, and the bud suffered frost damage. After the bud was frozen, it withered and died, and the flowering rate was greatly reduced.

The second is to choose the bamboo arc canopy film method: this method should be naughty. Fine bamboo is selected to be carved into bamboo slices with a width of 4cm. The length of the film depends on the width of the blue box. The two ends of the bamboo are inserted into the soil on both sides of the orchid box, and then according to the length of the orchid box, a piece of bamboo or a not too thick bamboo pole is placed on the frame and fixed with a thin rope, then covered with a thin film as long as the orchid box, and the parts draped out on both sides are opened against the wind, leaving air gaps in all directions can also be fixed with ropes. No matter how big the frost and snow is in this film shed, the orchid will not be affected by frost. In the whole frost and snow condensation season, according to the ratio of rainy and sunny days, the dryness of the soil can be opened and watered with film, and according to the length of time covered by the film, the orchid can be exposed to fresh air and enjoy the warm sunshine in cold weather. This way is to be more complicated and patient. Once a year.

For this reason, if you choose the second way, you should set up the curved scaffolding as soon as possible. Cover the film to prevent frost when there is a bright frost. And then wait for the frozen snow to fall on nine cold days to temporarily avoid being in a hurry to avoid freezing the orchids!

The author uses both methods. The three boxes of orchids made of firebrick above the bungalow are made of vertical columns, and the garden is covered with thin film with bamboo arc scaffolding. As soon as we entered the frost day after Frosts Descent, depending on the frost, we covered the orchids with a film to prevent frost and keep warm. Therefore, in recent years, the leaves of Lanmiao orchid have not been damaged by frost, the leaves of orchid are green and beautiful, and the flowers are beautiful.
