Open ground shade from rain and dew

In areas where there is basically no frost and little continuous rain in the south, orchid seedlings can be planted and domesticated in the open field. Sunshade and rain shielding arches should be set up when planting seedlings. From midsummer to mid-autumn, due to the scorching sun, there should be a sunshade net that can block 60% of the light, and keep it in full sunshine the rest of the time. If there is continuous rain, it should be covered with plastic film at any time to protect it from rain. At ordinary times, according to the need, timely water supply, fertilization and spraying. It is necessary to prevent frost during the frost period. This kind of extensive management is similar to the wild condition, the survival rate can be as high as 95%, the germination rate is more than 2%, the growth is gratifying, and there are few diseases and insect pests.
